HI im wanting to setup a study lab containing several windows 2012 r2 servers (mixture of core and full installs) to allow me to study towards my MCSA in server 2012 r2 and then for MCSE.

Physical equpiment, 

1 pc   which is has window 8.1 pro installed from this machine.  This machine i would like  to remote manage and connect through to my Hyper-v server and then into any of the virtual machines. (this machine is more of a gaming pc so not able to run to many vm's from it)

2 pc bought Just for study  8 core processor 1 tb of hhd space 16 gb of ram.

This machine i would like to setup using hyper-v server 2012 r2,  which then i would create a test domain within it also with some clients allowing me to play and undstand the principles im learning.

now im getting conflictiong information regarding the Hyper-v server 2012.

If i set the hyper-v server up as a standalone in a work group.  Would i be able to manage ther VM's within the hyperv server from my external windows 8 pro machine using the remote server management tools or would i need to connect that pc to the domain.

Things I think i can do but not sure.   as im still learning

Could I setup a server 2012 r2 running AD dns and add the hyper-v role then wihtin that create the rest of the domain inside, allowing me from my other phyical machine log on to domain and manage all servers and machines.

Could I set up as i originally suggested, set up hyper-v 2012 server in a workgroup,  then create the domain within the hyper-v server but still connect from my external pc to manage the hyper-v and all the internal VM's within the domain.

I could run a Domain controller on a VM from my other windows 8 machine (within hyper-v or wmware), then on the 2nd machine install the hyper-v server connect it to the domain running from the other machine from what i can see, many people say this is the better option, BEST Practice, but this is only a lab and i dont require resilience.  and i would prefer to have my  as a sever manager via the remote tools.

So what i like to know if you can point me in the right direction either by a guide for someone who has setup a similar to me.

or tell which of the above options is possible or not so i dont waste anytime.

Network, i know i can do this virtually but i already have cisco routers and layer 2 swicthes so i may make the network lab via them.

Thanks in advance  for any help you can give me

Hi,

 I have Dell server with Win 2012 and Hyper-V server role installed. I was about to enable jumbo frames in Guest machines(2012 and 2008 R2) but I can only send frame with MTU 2002 bytes max, from wireshark analysis it seems that frames dont pass the hyper-v switch for some reason. The NIC is Broadcom Nextreme with mtu 9000(hyper- v machines have 9014 so I taught that was the issue but the problem occurs also with lower MTU in Guests). I have setup other servers (IBM and Dell with Intel NIC) and they work fine(have MTU 9014). Can anyone encountered this issue? Thanks.

Hello Everyone.

I would like to LiveMigrate a VM from HostA in AD Forest1 to HostB in AD Forest2.  There is a two-way trust established between the two AD Forests.  Does anyone know if this is possible?  I have not been successful.

I have Microsoft Server 20012 rt as a host machine running Hyper-V. Within Hyper V I have created a VM with the intention to import a previous VM from a External hard drive with USB connection. 

The issue arises with the local host  machine not reading the USB connected hard drive containing the VM file. 

How can I configure the local host VM to view the USB device, so that I can import the VM file?

I am currently copying the file from the external hard drive to the host computer's desktop so that I can access it through windows explorer via the local host. 

Hi Guys,

last night a have seen a strange behavior with a Sophos UTM 9.204020 Linux Guest VM. (This VM is based on SUSE SLES v11? i think)

So i have Setup this in my home lab and experienced the same problem.

----Setup-----

2 External VM Switches

Management OS is on VLAN 4093 with IP 192.168.20.1

The guest network adapter is in Trunk Mode, VLAN Tag (4093) is set in the guest OS with IP 192.168.20.100

Everything works until you kick off a reboot from the guest or hyper-v console, after the reboot you loose the connectivity on the network adapter with the vlan trunk.

If you shutdown the guest and start it everthing works again - this happens only on reboot!!

I have tried diffrent things (static mac, enable disable hardware features (vmq/offloading etc) on the vm network adapter but always the same error.

After some search on the net i have found this article: Link 

This guy has the same problem with another linux vm (based on debian) his workaround was to trigger a powershell script with the eventlog after reboot of the vm, this works for me too but this must be bug?

Has anyone else experienced this problem?

I hope this is in the right forum.  I have done a lot of research and searching but havent found anything that specifically answers, in total, what I am wanting to accomplish.  I live in a small town and want to start a Managed Cloud Services for small to small-medium business in my area (2-30 users for each business).  I want to market this to have businesses replace their in-house server(s) to virtual ones I would host in a local Data Center with my own equipment that I would maintain.  I am just starting off so I don't have any clients I do this for currently, but I get asked about this frequently.  I want to run a 2012 R2 Domain Controller and a Hyper-V 2012 R2 server.  The virtual servers I will host are going to be for AD, RDS, FTP, and files.  Software examples that people are going to be using these virtual servers for are Quickbooks, Sage Accounting, Remote Desktop or RemoteApp, custom CRM or small database software, Office 2013, etc.  No Exchange currently but will probably configure something for that in the future (maybe run 1-3 virtually for now if someone asks, but will only do it if the user base is fairly small ~under 10 users).  I only have 1 static IP to work with over a 100Mbps connection up and down.

For hardware, I am figuring something along the lines of this:
(1) 1U, single CPU w/2-4 cores, 8GB, 2x73GB SAS 10k RAID 1, Dual PSU, running Windows Server 2012 R2
Domain Controller
(1) 2U, 2x 8-core Xeon ~2.6Ghz, 80GB RAM, 8x600GB SAS 15k in Raid 10 for Storage (VHDX files, etc), RAID 1 small Basic drives (or USB stick) for OS, Dual PSU, Quad GB Nic which I can use for load balancing/teaming, Hyper-V 2012 R2
Hyper-V Virtual Server
(1) GB Unmanaged Network Switch & (1) Cisco 5510 Firewall

Most of my questions are about the best way to configure this.  I am planning on managing my Hyper-V from the physical Domain Controller server.  Each virtual server will have RDS & (possibly) AD services on a single server.
1)I want to replicate the physical Domain Controller.  Should I get another server or just virtualize the replica in Hyper-V?  I understand that if the Hyper-V goes down, so does my DC replica.
2)Should I use my Domain Controller to manage ALL users on each virtual Server, by creating separate Organizational Units for each business?
3)Should I setup my domain controller with Hyper-V management and then each Virtual Server I setup be a separate domain (Ex. mydomain.local, business1.local, business2.local, etc)?  Each one has no connection to any other, completely seperate.  Or should I do subdomains (business1.mydomain.local).
4)What I have read is that Subdomains are a pain to manage with user rights, etc.  I want to keep each server complete separated from one another over a network connection, I suppose the VLan through Hyper-V options do this?  I dont want wondering users to stumble upon another businesses files (I know they would probably be prompted with a login for that business/domain).
5)For each virtual server, I want to create and have an HTTP subdomain point to that server from my domain name. (Ex: business1.mydomain.com, business2.mydomain.com, etc.)  I want them to be able to have access to only their RemoteApps or be able to type that address in their Remote Desktop program as the host name.  This would be for viewing the RemoteApp login page and RemoteApps for that business over HTTP/S through a browser.
6)If I do not have separate DC's in each virtual and my main DC manages each one, is their a way to connect up each companies RemoteApps using a single site that only shows what they are assigned to based upon their login? (Ex. http://login.mydomain.com which then shows that user what they are assigned on their own virtual server)
7)Since each business will use the same ports for RemoteApp (443) & RDC (3389 unless I change it), how would I setup the subdomains to point to their correct server and not overlap for mess with any of the other servers since its all over 1 static WAN IP for all servers.  Thats why I figured setting up IIS subdomains would solve this.
8)For backups or Hyper-V replication, is it better to have software that backs up the ENTIRE Hyper-V server (Acronis Advanced Backup for Hyper-V) as well as replication or just backups?  Or should I do separate file backup on each virtual with a replica?  Can a replica be a slower server since its just a backup? (Ex. 1x 8 core, 80GB, 8x600GB 10k SAS)
9)For the servers that will be using FTP, can I again rely on the subdomains to determine which server to connect to on port 21 without changing each FTP servers ports?  I just want each business/person to type in the subdomain for their business and it connect up to their assigned FTP directory over port 21.
10)If the physical DC manages DNS for all Virtual servers, can I forward sub domain requests to the proper virtual server so they connect to the correct RemoteApp screen etc.  Again all I have is 1 IP.

I hope all of these questions make sense.  I just want every business to be independent of each other on the Hyper-V, each on their own virtual server, all without changing default ports on each server, each server running RDS, (possibly) AD, (a few) FTP, and all over a common single WAN IP.  Hoping subdomains (possibly managed through IIS on the physical DC) will redirect users to their appropriate virtual server.

Hi.

I have a Hyper-V 2012 cluster with 5 nodes. All HP Blade servers in the same enclosure, on 3PAR FC SAN storage. I wanted to run routine maintenance on the hosts, i.e., Windows Update. So I Live Migrated the VMs off one host at a time, paused it in Failover Cluster Manager, rebooted, unpaused, and failed the roles back manually.

After updating the second host, I decided to fail the roles back when unpausing. The instant one of the VMs moved back to this host, it failed to start, and got a red X in FCM.

The VM had 2 virtual disks. I removed one, leaving only the system disk. When I started it, it ran CHKDSK a couple of times and eventually came back, appearing to be healthy (a miracle!). But I cannot add the second VHDX to the VM. It throws an error:

Hi all,

I find an error in the hyper-v manager.It shows that while bringing up interface eth0,some other host already uses the saMe IP.when i change the IP,the same error occurs.what to do?

Hi..

I am a BMS engineer working with Webtalk.

In hyper V manager I found an error shown below

Diplaying interface eth0:error,some other host already uses the IP address 192.168.1.34  [FAILED]

even after changing it to 192.168.1.35 or similar number,the same error persists.can u suggest a solution?

NOTE:the same trouble for eth1

hi ,

I want to generate graph of total  Hyper-v CSV used space

we use scom and i can get graph of each volume individually.

I want to create a summation graph to know average growth rate

Hi gents,

Yesterday we had a very odd issue during our scheduled SAN maintenance.

We are using Flexpod architecture in our Hyper-v environment, Netapp SAN, Cisco UCS blades and Nexus switches.

Last night when we shutdown the SAN for maintenance all Hyper-v hosts stopped working! even the OS, a few of them with blue screen! (we DO NOT use boot from SAN, each blade has its own disks). However QUORUM was up

Any Idea of what went wrong?

This was also supposed to be fixed in HV 2008R2 with a KB!

This is what I'm getting in eventlog:

http://postimg.org/image/8m0xw0tz7/

I've just installed a new domain. It has one domain controller (Windows Server 2012 R2), SVR0 and one Hyper-V Server (not the Hyper-V role...Hyper-V Server), SVR1. I joined SVR1 to the domain and now I wan to manage it from a Windows 8.1 client. I've installed RSAT on the client and I can open Server Manager no problem. The problem that I am having is that there is no sign of Hyper-V manager anywhere. Server Manager knows that SVR1 is a Hyper-V server but still there are no Hyper-V Manager links anywhere. I was expecting it to show up in the tools menu on Server Manager but it did not. I made sure that Hyper-V management feature is installed on SVR1, but still nothing.

What am I doing wrong?

I have a two node Server 2012 R2 Hyper-v cluster built from SCVMM 2012 R2. I have created a virtual switch that is bound to a LBFO team (8 x 1GB Nics) on each host. Logical Networks are all defined with different VLAN IDs and subnets. I have created different vNics for the parent nodes for different cluster networks as follows:

Management: 10.226.208.128/26 (VLAN 100) - this is the only NIC with a default gateway.
Live-Migration: 172.16.2.128/26 (VLAN660)
Cluster-CSV: 172.16.3.128/26 (VLAN661)

Each of the host vNics that are connected to the virtual switch have VLANID's defined.

However I am seeing some strange behaviour with cluster network traffic being blocked by our perimiter hardware firewall as follows:

100: access-list ACL109 denied tcp DMZ/10.226.208.188(62786) -> LAN/172.16.3.133(3343) hit-cnt 1 first hit [0xba094209, 0x0]

(Here I would expect the TCP 3343 traffic to go from 10.226.208.188 directly to 10.226.208.187 or from 172.16.3.134 to 172.16.3.133).

HYPERVHOST1
vEthernet (Management: 10.226.208.187)
vEthernet (Live-Migration 172.16.2.133)
vEthernet (Cluster-CSV: 172.16.3.133)

HYPERVHOST2
vEthernet (Management: 10.226.208.188)
vEthernet (Live-Migration: 172.16.2.134)
vEthernet (Cluster-CSV: 172.16.3.134)

Any ideas what I am missing here?

Hi Guys,

We have the following setup for our testcase:

- HP ML350 Gen8 Server
- Windows Server 2012 R2 Hyper V role

On that:

- Windows Server 2012 R2 VM Gen2 (also tested with Gen 1, same result)
- Windows Server 2008 R2 VM Gen2

We installed Desktop Experience on the 2012 R2 guest and tested the following website:

http://abowman.com/google-modules/fish/

When we go to this website, we get the following results:

Windows Server 2012 R2 Gen 1: 20-30% CPU
Windows Server 2012 R2 Gen 2: 20-30% CPU

This is on Internet Explorer Only.

Chrome will go to 100% CPU with this website (or any other flash related website)
After this, we added the following parameter to Chrome.exe %disable-gpu %U and the CPU dropped to as little as 20%-30%.

Same results as IE.

On Server 2008 R2 (with RDS enabled) the CPU is normal (0-3%) on the same host (Hyper V, Gen 1 or 2)

So we wanted to test this on our VMWare Platform to test if this was an Hyper V issue or an Win2k12 R2 issue.

Result were strange, every image (Win2k8 R2 or Win2k12 R2) with IE gave no problems.
Chrome with GPU disabled gave an lower result (11% CPU) then Hyper V.
IE was 0 to 4% CPU.

Everything was testen on the same hardware with 2 virtual cores.

We did nothing yet with RemoteFX because we do not have the hardware for it at the moment, but it cannot be that we need to enable RemoteFX card to get some better performance on the guests!

Anyone else experienced this? Is this known? Can't seem to find any information about it!

Flash bug with IE11/Hyper V/Win2K12 R2?

Any help is appreciated!

We've inherited a client with existing hyper-v VM's, one of which is their remote desktop server running server 2012 - this particular VM has 256MB of graphics memory and they run CAD software on it.

Does anyone have any idea how the previous tech managed this? RemoteFX is not enabled, nor is dynamic memory and I've found no way to change or reproduce this, any ideas would be greatly appreciated!

I have a problem where one of my 2008 R2 virtual servers are shutting down unexpected every Friday at more or less the same time. This has happen 2 Fridays in a row now and the time is 13:01:30 and 13:01:10. I did some investigation on the event viewer and it tells me the following: (Error) The previous system shutdown at 01:01:10 PM on ‎2014/‎08/‎01 was unexpected.  Event ID: 6008 which I have goggled and did not find much on this ID?    I also found the following event more or less the same time as the first one: (Critical) The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly. Event ID: 41.  In most posts it looks like if it could be hardware related? But how do I justify this on a virtual machine?

Some Infrastructure background: It is a 2008 R2 virtual server running on 2012 Hyper-V, 2012 server. SCVMM is not configured so all administration is done through Hyper-V manager. The virtual machine is backup up by Symantec backup exec and the Full backup only start at 23:00pm night time. No scheduled shut-downs are configured and all servers are running on UPS power, the virtual server are also configured to boot up automatically after any failure. But in this case the server is completely shut-down and I have to manually start the server up again.

I hope there are somebody who can give some guidance on my problem?

hi Team ,

i recently build 2012 R2 Hyper-v Cluster with three node. Everrything working fine with out any issue . Cluster working also fine. Later i came across one issue when tried to Live migration virtual machine from one host to another . it failed all the time while quick migration is working . i gone through few articles and find it is known issue with hyper-v 2012 R2 where domain functional level is set to 2003 . although they have provided Hotfix but no solution.http://support.microsoft.com/kb/2838043

Please let me know if any one face similar issue and able to resolve by any hotfix. My host are updated .

Thanks
