My HyperV server has two quad ethernet port cards in it and the first 4 are in a Team with the virtual Switch with a static IP, DNS and Gatway.
The other card has two of 4 nics disabled and two of those nics have a static IP without dns or gateway used for iSCSI multi-pathing.
It is not uncommon for me to log into the HyperV box and find that it has "no internet connection" and after a reboot it may be up for a short while but eventually it fails. Also after a while it will lose time and you cannot RDP to it at all! I have to physically login to it and reboot it.
I am including screenshots of me setup to help aid in any information that may be needed to help me figure this out:
Please help me!
Thank You!
Hi
Im currently studying for my 70-640 exam and i have a server built up at home for this. im running Windows server 2008 R2 with Hyper V role installed. i have 2 Virtual servers install that i use for my course.
now the question is this. my home network from my home router runs on the (192.168.0.X 255.255.255.0) network range
but my book specifies that my virtual machines to be run on the (10.0.0.X 255.255.255.0) range
is there any way i can do this. so that the virtual machines can run on the 10.0.0.X range and still talk out the the internet through my home router? which is on the 192.168.0.X ????
i cant seem to get my head round this one on how i can accomplish this
any help would be appreciated
thanks
Hi. Im having an issue in my lab testing out the shared vhdx functionality of 2012 R2.
The hardware is as follows2x HP DL380G5 with 2xHP P800 Smart Array controllers 2x500GB SATA SSD 2x1TB SATA HDD. Ive used Starwind to create 2 Cluster Shared Volumes on which my shared VHDX files are.
The issue im having is that after the creation of shared vhdx files (3-4 hours) any failover change in the vm configuration will result in Error opening handle for initiator. Initiator: {460b2b45-2f5a-485f-b045-60b68b655895}. Hostname: HYPERV1. File: \SQL QUORUM.VHDX:SHAREDVIRTUALDISK.
Error: The request is not supported..
Ive set the ISCSI sync adapters to "dont allow cluster and client communication" and prevented it being registered in dns (nslookup only shows one ip) yet every shared vhdx has this issue.
Can anyone suggest if this is a hardware issue or software ? It is such a timesaver compared to multipath io and iscsi on the guests id like to get it working.
Hi,
I'm having this very strange slow network problems on a Windows 2012 R2 Hyper-V cluster.
In the process of troubleshooting, I've simply the setup to the following:
2 Physical node, with one 4 ports Intel 1Gbps card and on 2 ports Intel 10Gbe card in each node. The nodes are setup in an Hyper-V cluster running Windows 2012 R2.
The 2 10Gbe ports are used for the cluster communications.
2 of the 1Gbps port are connected to a virtual switch (completely separate switches), so I have two Hyper-V virtual switch I can use to connect virtual machines (I removed teaming from the original configuration to make sure that wasn't the problem).
Here is the problem:
If I create a new virtual machine (windows 2012 R2 or Windows 2008 R2 guests - tested both) and connect it to the first virtual switch (let's call it Switch A), If i then copy a file from that virtual machine to another physical host on the network (outside
the cluster), I get a normal 110MB/s transfer rate (no problem here). From the same guest, If I then start a file copy to another virtual machine (outside the cluster to either Hyper-V or VMWare VMs), I barely get 10MB/s!
Here is the bizarre thing: if I now connect the Guest to the other virtual switch (Called it Switch B), the transfer rate are inverted: I get 110MB/s if I copy to any VM, and I get 10MB/s if I copy to any physical server!
So using Switch A, I get great network performance to physical hosts, while crap performance to VMs, while using Switch B, I get the total opposite!
The two ports used are located on the same physical network card (4 ports card), with the same firmware and driver (latest from Intel)!
I'm lost... Anyone has seen this before?!
Thanks,
Stephane

Hello.
I'm bit confusing and can't find straight answer for my problem. We have a server with 1 physical CPU with Windows server 2012 Datacenter installed, activated and running Hyper-V. Now that we have installed another Windows server 2012 as guest OS in Hyper-V, how do I assign a license and activate it to the guest os? Or do I need to purchase another Datacenter license for the guest OS?(Well of course it would be better to install standard version...)
The bellow statement is for ESX/ESXi, but from that point of view I undestand that I could run two separate installations of Windows server 2012 in one machine, with only 1 license. Can this be done in Hyper-V as in the scenario that I wrote?
"If you have assigned a single license for Windows Server 2012 Standard to a server running ESX/ESXi, then you may run two instances of Windows Server 2012 Standard at a time. The right to run an instance of Windows Server 2012 in the physical OSE cannot be used in this case since ESX/ESXi runs on the physical OSE (and as a result, Windows Server 2012 cannot be deployed as the operating system on the physical OSE.)"

Hi All
I need to convert Hyperv generation 2 VM's on a Windows 2012 R2 hyperv server so I can export / run them on a Windows 2012 (NOT R2) HyperV server.
Is there anyway as currently they won't boot on a Windows 2012 (non R2) hyperV servers
Thanks

Hi all,
I am using Server 2012 R2 with Hyper-V, HP DL360 G6 Server
The Master OS have a NIC1 to VLAN1 Switch (Also in the Cisco SG300 Switch)
Plus other NIC2 connect to Cisco SG300 28 Switch (Running in L3 Mode), this Cisco then connect to a SonicWALL NSA 2400.
I build some VLAN31 on SonicWALL NSA 2400, and add this to the Cisco SG300 as Truck Port connect Both...
Other Port on the SG300 are untouch, so mean default running mode is Truck mode, and one of it port connect to the NIC2 to the Server ...
Ok, if Hyper-V VM, not enable VLAN in the Hyper-V Management in 2012 R2, it can take the DHCP from the SonicWALL NSA 2400 no problems, can see other LAN (VLAN1) machine well both direction, and go to Internet too.
But, if I setting the VLAN31 on Hyper Manager to some VM, it can take the DHCP and take the IP from SonicWALL for this VALN31, include DNS, GW etc...
But ... it just can ping internet, for example, ping www.yahoo.com it ok, but open IE, enter www.yahoo.com will super super slowly and time out, if running CentOS 6.5 Linux, enter yum update, it total not work, time out, 0.2kb/s etc. But it can ping to www.yahoo.com
no problems...
And If Windows run routert www.yahoo.com, over 10s to see next hub ...
I am double checked SonicWALL NSA2400 Firewall Policy is allow all VLAN and LAN to WAN, and VLAN TO VLAN too..
What is wrong on the Hyper-V VLAN? Do I am setting wrong of my switch port mode (Access/Trunking)?
I am now out of direction what is go on to troubleshooting this.
Thank you.
Hi there
does it possible to join to virtual domain from windows 8.1 host or not ??
I installed windows 8.1 on my system as host windows and then enable windows 8.1 hyper-v and installed windows server 2012 r2 and installed active directory domain service
now I want to join to this domain from my windows 8.1 but I can't . I create a user in active directory users and comupers and do it's DNS but can't complete .
give me this Error that may be the domain name is not correct or the user name or password is incorrect
please help me how can I join to virtual domain from windows 8.1 host in my pc ??
thanks

Hi,
Just found a blog about fixing corrupt VHDs.

Hi!
I have installed Hyper V, and I'd like to convert my vmdk (vmware) to vhd files.
In order to do that, I download this:
http://vmtoolkit.com/blogs/announcements/archive/2006/11/20/vmdk-to-vhd-converter-available.aspx
The result is a file very small (56kb) whereas the size of my virtual hard disk is 8Gb.
Then, I attach this file (vhd) to my VM but the system doesn't boot. Why?
Thanks
Hello,
while I am doing Backups (DPM2012) of my virtual machines, I see the following error:
'VMNAME': The Data Exchange integration service is either not enabled, not running or not initialized. (Virtual machine ID 2C69E8FF-32C2-4489-BE06-FEFFD2DA4C13)
The command get-vmintegrationservices of the VM shows:
VMName Name Enabled PrimaryStatusDescription
VMNAME Time Synchronization True OK
VMNAME Heartbeat True OK
OK
VMNAME Key-Value Pair Exchange True OK
VMNAME Shutdown True OK
VMNAME VSS True No Contact
VMNAME Guest Service Interface False OK
All needed Services are up and running.
When I check the VSS Writers in the VM there are all Writers in stable state with no error
Hyper-V Host is running on Windows Server 2012 R2
Integration Services are up to date (6.3.9600.16384)
VM is Running Windows Server 2008 R2
The backup with DPM of the VM using Hyper-V online backup is successfull.
Does someone know, what these errors try to tell me?
Thanks.

We have moved from vmware to hyper-V virtualization.
We have windows server 2012 and sql server 2012.
When executing some query on SQL server the CPU time is much greater than CPU time for the same query on the same sql server with the similar resources but on vmware virtualization.
(the query doesn't produce IO, since all data pages are in RAM - so, the problem is CPU)
I have tested the most simple queries as the most complex queries with the same execution plans on both servers. There is always similar difference in cpu time, couple of times slower.
Is there some well known configuration of hyper-v, which is optimal for running sql server on it? What should i check, any idea?
I wanted to perform some long overdue maintenance on a hyper-v host. My setup is two Win2008 R2 Core Hyper-V machines with local disk storage (no san, no virus protection on the hosts). I powered down the Guest OS's, exported them from Virtual1 and copied the to Virtual2. The guest OS came up and worked no problem on Virtual2. Later on in the day I powered down Virtual2. When virtual2 came back up 2 of the 3 guest VM's have disappeared from the management console.
Some items of note...
Anyone have any idea what's going on? I'm kind of baffled as where to even begin looking.
Thanks for any help,

I tried to restore a copy of my VM that I exported a few days ago.
The target host is the same Windows 8.1 Pro computer it was exported from.
I used Import with the Restore option that retains the same VM ID. I want to replace the existing VM with an earlier copy of itself, not make a new VM. But it gave an error saying "The operation failed because a virtual machine with the same identifier already exists."
All I want to do is to wind back the VM to where it was when I exported it, and leave its name and ID the same.
Do I have to delete the current copy of the VM from Hyper-V first?
Dear All,
I have a strange issue with Hyper-V SCVMM 2012 SP1. "Enabled VlanID" is greyed out if I take VM properties in SCVMM 2012 SP1. But at the same time I am able to change it in Hyper-V host! strangely it doesn't happen to all VMs! Any help is appreciated as google doesn't give me any fruitful answer. appreciate your great support.
Regards,
I have a hyper-v Cluster running on Windows 2012 r2. I tried a live Migration from one node of Cluster to another node of the same Cluster. It got stuck by around 65% (if remembered correctly). After 45 minutes nothing has changed so I canceled the Job in the Failover Cluster Manager. The VM went into a Status of "Stopping". After 5 hours it is still in Status "stopping". I haven't found any Information on why it got stuck on the 65% and have just found the error message that the Job got canceled using Failover Cluster Manager events. But nothing saying why it stays in "Stopping" Status. Searched the Internet but I have Trouble finding anything related to the issue I see.
Any ideas?
We have 4-5 people in a software development environment with access to 4 servers, each with 2 quad-core or dual-core cpu's (core-based, before nehalem), and 8gb or 16gb RAM, so I think we have a good amount of power for virtualization. Total, we have a team foundation server, oracle server, web server, 2 virtualization servers, and multiple workstations, some virtualized, some not.
When we started virtualizing about a year ago, for whatever reason, and although everyone has an MSDN sub, we started using VirtualBox instead of Hyper-V. I'm no expert (and that's why I'm here) but I think they operate at different levels of interaction with the hardware, and that VirtualBox is a bad idea for this environment.
Can someone give some good reasons why we should be using Hyper-V? Also is it possible to convert the virtual machines?
And then I would like to know if it's okay to also be virtualizing our web server and oracle server, etc. We have only been virtualizing workstations. I think we really need to make good use of virtualization if we are going to be doing it at all.
Advice welcome also for virtualization best practices, backups, management, infrastructure design, etc. I would like to start with a domain controller, and maybe a Lync server so we can share desktops, etc. Thanks for all input!
