Hello I have try many diffent combo of configurations to get hyper to run on this but can't seem to get it too run Essintal server 2012 and 2012 R2 with Exchange Server

Server hardware is Amd opertron 4122

2 X AMD 4122 

ASUS  KCMA-D8

ASUS PIKE PIKE 1064E

WD X 2 TB RE4 

SEAGATE ES3 2 TB X 2

I have try diffent configrations for stoage  in raid  mirror out of raid storage spaces  on virtual machine am do 8 gig ram for essintal server 2012 and 16 gig ram for exchange server with fixed  vhdx  disk on storage space have also tried on raid volume mirrored  problem is after loaded exchange it become  super slow the machine run exchange become unable to open network connections

Any suggestions would be great

After several days of testing, I have come to the conclusion that there is a direct connection between the MPIO and iSCSIPrt event messages that I have been seeing on my HyperV Server 2012 R2 when the host starts up a VM that is running domain services.

I understand that in this scenario, (as best as I can explain it) that HyperV in conjunction with the VM AD DS services will attempt to disable write cache flushing on the controller.  I believe this article tells the tale:http://support.microsoft.com/kb/285395

as does this: http://support.microsoft.com/kb/2801713

However, since in this setup the VM's VHDX file is presented to the HyperV host via iSCSI using MPIO, neither the host nor the VM have the ability to disable this capability.  It is completely controlled on the iSCSI Target server (which does in fact have write caching enabled, but it doesn't matter... or it shouldn't matter in my opinion). 

It all starts on the HyperV host with Disk Event 32 (a write cache warning) during boot.  During the boot phase of the VM, and while the host and VM attempt to disable cache, MPIO will loose the path the iSCSI Target and MPIO will attempt to recover it.  The result is a slew of warnings and critical events logged in HyperV.  iSCSIPrt will throw these events (20, 7, 34...).  Event 7 being the most ugly and repetitive.  MPIO has it's own, and of course the initial warning from disk source (event 32).

I have noticed that some tweaking can be make to prevent the path loss in MPIO by adjusting the PDORemovePeriod, and enabling a CustomPathRecoveryTime.  But this will only stop the events logged by MPIO in the path loss.  The iSCSIPrt will continue to post events 20, 7, and 34, while MPIO will then (with adjusted timeouts), just acknowledge all of this temporary loss and say it was able to recover the path.

The only way I have been able to mitigate the iSCSIPrt events is by actually "enabling" write cache in the VM guest (which is in reality disabling flushing).  No longer will iSCSIPrt spew a dozen Event 7 critical messages and the others... MPIO, totally silent.

I still get the event 1539 in the VM guest (running directory services) which acknowledges and warns of not being able to disable write cache... but it couldn't do it before anyway!

So, I guess my question really is... what is the true risk here if I am not able to disable write cache on the hyperv host and VM in this setup.

Based on that article linked above:

"However, Active Directory requests all database updates be completed without caching, which the Hyper-V storage subsystem ensures in order to prevent data loss from a power failure or other unexpected reboot."

since that isn't possible when using a SAN that presents the VMs to HyperV... am I correct in saying, the risk is really on my shoulders then?  hasn't it always been though in a way to make sure things are shutdown appropriately during a power outage.

How can I mitigate this better?  Is there a tool I should be using between these two systems to coordinate the VM shutdowns, and eventually the host shutdowns?  or am I basically needing to do some powershell scripts between the hosts?

Hi, I am trying to connect to ws2012 hyper-v machine from win7 using the server-manager to manage hyper-v. I have no access. First step I tried was installed from the control panel the remote admin tool->hyper-v the ones comes with win7 but it has connection failure.

I found following article in which it says,

http://technet.microsoft.com/en-us/library/jj647785.aspx

"lthough Server Manager was available in Windows Server 2008 R2 and Windows Server 2008, Server Manager was completely redesigned for Windows Server 2012 to support remote, multiserver management, and to help increase the number of servers an administrator can manage. You must use the version of Server Manager in Windows Server 2012 R2 or Windows Server 2012 or that is available as part of the Remote Server Administration Tools. Older versions of Server Manager will not work. To download these tools, see :

• Remote Server Administration Tools for Windows 8.1
• Remote Server Administration Tools for Windows 8"

So I downloaded the Windows 8 version of this tool and attempted to install but it is certainly not installing. So here is the dead-end I am at. When googline there are lot of solutions availabie but each of item are different therefore I feel no wasting time trying each of the suggestion blindly. Question here is is it possible at all to manage hyper-v 2012 with win7 at all?

We are a small office (8 users) with a new server on the way.  We are running Server 2003 and CRM 4.0 and will upgrade to Server 2012 Essentials R2.  I would like to run this as a VM and integrate Azure's cloud backup.  The problem --and I'd like to be wrong about this -- is there is no included SQL server with Essentials 2012.  Our old server has SQL server 2005 which I believe was included.  Our database is only 1.6GB so we could use the free version of SQL Server 2014, but it is limited to one CPU.  Our new server is dual CPU, 8 total cores.  My thought is to use P2V and make a virtual machine from my current 2003 server, then run that inside the Hyper-V environment along with 2012 Essentials.

So I have two questions?  Does the Essentials (or Hyper-V) licensing permit me to run any more VMs than the single instance of 2012 Essentials?  And secondly, will the primary 2012 Essentials installation acting as the Hyper-V administrator be able to use Azure to back up both virtual machines?

If I am acting on any incorrect assumptions please correct me.

After adding hyper-v role to 2012r2 all was working fine until last week when VM's stopped and now I can no longer start any of the VM's or new one that I create. 

After much searching it seemed to be a permissions issue but none of the suggested solutions worked. I uninstalled Hyper-V role and added it again, no errors were reported in this process. I then started Hyper-V manager with process monitor tracing VMMS.exe and VMWP.exe and I see registryopenkey error with keys not found and/or access errors and file access errors. 

This happens at Hyper-v manager startup as well as when I try start VM's but the only error in the event log is a error 3040 Can not initialize VM.

Here is a snip of the process monitor for Hyper-V Manager startup:

Am at a total loss, any help appreciated.

Slow Preformance on HyperV VM's with IIS. Not sure what to change. Doesnt apear to be a Disc I/O issue. Seams to really on happen on VM's that are hosting a mostly static Intranet page. Also same thing happens on another VM that hosts an Apache site. both are not very large and VM's run on a Local storage space seperate from the OS and good I/O speed. Host Server gets good network speeds. I have the Host and the VM fully updated.

Host Server is Windows 2012 and Hosts are Windows 2008r2

I've gone thur the Hyper V Preformace Blogs and tried to apply all the hot fixes. but most I downloaded said it did not apply to our machine. So Not sure what the issue is.

Hi.

I got a HP DL380p with 13 SSF Hard Disks and 4 SAS SSD.

SAS SSD will be configure as 2x RAID 1.

Will be deploying a VM running Windows 2012 R2 STD and Oracle.

I need to create four (4) VHDX, spread across the following

(6 Disk) RAID 10 = VHDX 1 (OS) Drive C

(6 Disk) RAID 10 = VHDX 2 (DATA) Drive D

(2 Disk) RAID 1 = VHDX 3 (LOGS) Drive E

(2 Disk) RAID 1 = VHDX 4 (LOGS) Drive F

Questions

1. Can I replicate all 4x VHDX to a second server?

2. Since, my second server will only have 8x 4 TB SAS Disk configured as RAID 6 with a single Logical Volume,

can I have all 4x VHDX stored on the SAME Location.  Let say C Drive only?

3. Can you replicate Pass through Disks?

Thanks,

Paul

We Have Three Hyper-V Host with Shared Cluster.

Hyper-V Host 1= CS1

Hyper-V Host 2 = CS2

Hyper-V Host 3 = CS3

I am successful able to live migrate VM’s from CS1 to CS2 and CS2 to CS1 but unable to live migrate CS1 & CS2 to CS3

Following Error is Recorded at cluster Manager

Event id : 1205

Cluster resource 'Virtual Machine CS-FileServer' of type 'Virtual Machine' in clustered role 'CS-FileServer' failed. The error code was '0x2' ('The system cannot find the file specified.').

Based on the failure policies for the resource and role, the cluster service may try to bring the resource online on this node or move the group to another node of the cluster and then restart it.  Check the resource and group state using Failover Cluster Manager or the Get-ClusterResource Windows PowerShell cmdlet.

hi,

I am trying to setup a VM Replication from non-clustered VM to a clustered server, everything is going smooth but at when it start replication it come with error messag below is snap of the error message

Good Morning everyone, now here is my problem.

My company is a small software development house and we test our software on Win 7 or 8 VM's running on standalone (ie not on the domain) VM's. We are running the VM's on WS2012 R2 Hyper V and when we are inside the building we are able to Remote Desktop onto these VM's direct without any problem. The problem comes when we want to RD onto the VM's when working from home via the VPN. When we try to connect to the VM's via RD through the VPN the Remote Desktop Connection fails with the following alert "Remote Desktop can't find the computer '[Computers Name]'. This might mean that '[Computers Name]' does not belong to the specified network. Verify the computer name and domain that you are trying to connect to." The only way I can connect to the VM's is by going onto the host server and access the VM's via Hyper V manager and use it that way.

Now when I try to connect to a VM that is running on the Domain via the VPN I connect without any problems at all.

So my question is why can I connect to standalone VM's via RD without any problems when in the office but when I am at home via VPN I can't but I can connect to VM's on the domain without any problems? What do I need to do to make this work?

Greetings,

I'm having to clean up a mess left by a former co-worker and need to know how to transfer a Server 2012 license.  My former co-worker used one of the Server 2012 license keys on a Hyper-V server, which I was told doesn't need one as long as it is solely used for Hyper-V.  Is there a way to transfer that license to a new install of Server 2012 within Hyper-V or am I SOL?

Thanks in advance!

Matt

I'm just trying to get a definitive answer to the question of can we enable Bitlocker encryption within a VM that's housed on a hyper-V 2012 R2 host?

Some posts I've seen say it can be done and detail the steps, but others suggest that you can only use Bitlocker on data drives within the VM and not boot drives.

Can anyone please clarify the situation for me?

Cheers for now

Hi all,

Few times i have faced anniong issue. All times it was issue with Exchange 2010 VM's (Different Exchange servers from different domains). HyperV 2008 R2 and 2012 R2.

Server lost network connectivity from all other subnets. But in local subnet everithing is Ok. Most of communications is in local subnet but send/receive connectors stops working. After VM reboot everything becomes fine.

MAybe this is not HyperV issue but I saw those problems only vith virtualized Exchanges.

Maybe someone have seen similar issues and can provide solution.

I'm a little confused, but does the Hyper-V Managment Console exclude the number of days a machine has been up for??? 

These machines have been up for more than 4 or 5 days... Is there a way to change this?

Thanks!

Tony

Everyone,

We currently have a Dell R710 server with 4 onboard 1gb nic cards.  I want to team these for we will be running virtual servers off this box, and i would like the added benefit of combining these cards bandwidth as well as load balancing / fail-over if a card fails/etc. 

Can someone help me with getting this going?  I am not sure if what i've done falls into best practices, but here's what i've done so far:

1) I gave each network adapter a static IP (no VLANS in our setup)
2) When I installed Hyper-V, I set up a vEthernet External switch on each network interface.  
3) I'm ready to setup a nic Team, but i'm stumped as to how to do this.

When I go to create the Nic Team, it has the following listed:
vEthernet 1, 2, 3 and 4

It does not list my physical ethernet network adapters.

When I try to create a nic team of the 4 vEthernet adapters, it fails with the error "Operation timed out: TeamNic installation did not complete in a timely manner"

Can someone point me in the right direction of getting this going? 

Thank you! 

Does anyone have a copy of this they can send me please !!

I've got 25 Hyper-V machines running on a Remote Desktop Services server.  The main image was sysprep'd and all subsequent images were created off that (from within Remote Desktop Services).  All images came through as expected, booted up, logged in and half of them are displaying unauthenticated to the LAN.

I have a 4 port NIC setup within Hyper-V to perform Teaming. 

Hyper-V Setup in Server Manager

• Teaming Mode: Switch Independent
  
• Load Balancing Mode: Hyper-V Port
• Standby Adapter: None

It's also set to a specific VLAN of 30.

Hyper-V Virtual Switch Manager:

Connection Type

• External Network / Microsoft Network Adapter Multiplexor Driver #2 (there's an seperate card doing a dfferent function)
• Allow Manager operating system to share this network adapter IS Check Marked

VLAN ID

• Enable virtual LAN identification for management OS IS CHECKMARKED
• VLAN ID : 30

I have no problems at all talking to any network device, pings and tracerts work properly.  I'm using this set of Hyper-V machines as destinations for Zero Client machines; meaning they access these machines through Remote Desktops.  That part works great. 

My issue is accessing a specific application as it seems to time out quite frequently.  The only thing I can point to is the potential LAN displaying Unauthenticated.  Any advice for this issue?
