2012 Hyper-V Guests Very Slow to Boot
We have two identical Dell PowerEdge T410's running Windows Server 2012 Standard running as Hyper-V Hosts (and nothing else).
The Hyper-V guests on one of the machines take over 40 minutes to boot. Once booted the VM's seem to perform well. The second T410 is running without any problems.
The Dell has 40Gb RAM and has 12 virtuals, the 5 XP virtuals are running with 1 GB RAM each and the 7 Windows 7 VM's have 2 Gb.
When everything is running, the Dell's task manager says it's using 22.9 of 40Gb RAM and the CPU is ticking over at 1 or 2%.
I've just wiped and re-installed the host with a clean Windows Server 2012 with no improvement.
Dell's technical support has had a quick look and can't see anything wrong with the hardware side of things. The BIOS settings in the problematic machine has exactly the same settings as the BIOS in the machine that is working OK.
The clients on the 'slow' host are all part of a domain with the domain controller on the 'good' host. Tracert and ipconfig all report as expected.
A 'Google' has turned up a couple of articles which seem to only refer to Windows Server 2008 R2, however, the problem only started to appear when I installed Server 2012.
So, in a nutshell, two identical servers, the guests on one are working fine, the guests on the other take over 40 minutes to boot.
Could anyone give me any pointers?

Adding 3rd Node to Hyper-V Cluster with different CPU Class
Hi,
We have a Hyper-V Cluster with 2 BL 465 G7 Nodes which have AMD 6136 2.4GHz 8C Processor. Would there be a problem if I add BL 465 G8 with AMD 6212 2.6GHz 8C Processor. I am unable to get BL 465 G7 with 61xx series processor.

Is Hyper-V Server compliant to FIPS (Federal Information Processing Standard) 140-2 ?
Hi,
I was searching for whether Microsoft Hyper-V Server FIPS (Federal Information Processing Standard) 140-2 compliant? While searching on this topic, I could not find any references for the same.
Appreciate your help.

How can I install a Win 2012 R2 Hyper-V host inside Win 8.1 Hyper-V without resorting to VMWare
Using a Win 8.1 Hyper-V environment , I want to be able to install and test a clients new system environment.
This is a Windows Server 2012 R2 Hyper-V host with two win 2012 R2 VM's running inside it
I get the error message "hyper-v cannot be installed a hypervisor is already running "
I understand from google that it is possible to work around this using VM-Ware, is it possible using the Wn 8.1 Hyper-V or am I forced to migrate to VMWare?
Cheers

Server 2012 r2 guest issues
I am trying to figure out how to resolve this issue. I have a server 2012r2 HyperV box and on there i have a guest that has an extra 25TB VHDX. If i boot the machine with the VHDX attached it just sits on the windows boot screen forever. It boots fine without the drive attached.
I found a work around to get it to boot. If i change the scsi chain location it boots however the disk is "offline" if i try to bring it online it throws Errors

RDSH performance on Hyper-v 2012
Hi,
I want to update a little farm of XenApp & XenServer, to Windows 2012 RDSH VM Under Hyper-V (and failover clustering).
Is it good to mix Windows 2012 RDSH VM with others VM (like: Windows 2012 and Exchange 2013 Client access server, and/or Windows 2012 and BES,...) under Hyper-v 2012?

Server 2012 Gen 2 VM hosted on Server 2012 R2 Hyper-V Host incompatible with Integration Services after Windows update
If you take a Server 2012 R2 Host and update it, and then setup a Server 2012 and 2012 R2 Virtual Machines on it with the latest Integration Services. Setup SR-IOV on both VMs. Everything will be ok in the Integration Services status, but when
you update the Virtual Machines, the Server 2012 R2 will continue to report that it's up to date. But the 2012 will show that it needs it's Integration Services updated, when it's already running the latest Integration Services. I'm not sure which
update it is that is causing the conflict, and don't have the time to install 60 of them 1 by 1 to figure it out.

IMPOSSIBLE to Stop Windows 7 VM in Hyper-V!!!
I'm running HYPER-V on a Windows 2012 box. I have a problem that countless others have found - a Windows 7 VM refuses to shutdown and gets stuck in an everlasting STOPPING state. After several days of searching and research, I found a promising thread that suggests I use a LEGACY NIC in the VM. I was able to successfully remove the BROADCOM NIC from one VM and add a legacy nic. Works flawless now - albeit very slow in shutting down.
I've got one other VM however that I'd like to remove the Broadcom NIC from and add in a legacy NIC. Unfortunately, I CANNOT shut the VM down! No matter what I try, it sticks in the STOPPING state. I've tried the following:
1. Tried to SHUTDOWN straight from the OS interface (START button). Sticks in the STOPPING state.
2. Run PROCESSEXPLORER as administrator; attempt to kill the vmwp.exe process. Will not die - get ACCESS DENIED after 2nd attempt.
3. Tried killing the HYPER-V service and restarting. Does not stop VM.
4. Tried stopping the VM by going directly to the ACTION menu, and using TURN OFF. Sticks in the STOPPING state.
5. Tried rebooting Windows Server 2012 box after all of these actions and the VM shows as RUNNING after a server restart. If I open the VM after a restart it runs fine. I just can't shut it down!
I'd love to be able to change the NIC to a legacy NIC and see if this fixes the problem but for the life of me I CANNOT find a way to stop the VM so I can change settings! You'd think with the number of people exhibiting the problem Microsoft might try to address it - but to date I've not found a solution to STOP the VM so I can change settings. HELP!

How to change the network configuration of a virtual machine from its host machine?
Hello,
The host server is Windows 2008 R2 with Hyper-V,and the OS of the virtual machine on it is Windows 2003.
I don't have the admin account password of the virtual machine, so I can't log in the OS to change the network configuration(IP,mask,gateway).
Now I wonder how to change that from the host server,I find an article about it:
http://blogs.technet.com/b/m2/archive/2010/07/29/how-to-get-the-ip-address-of-a-virtual-machine-from-hyper-v.aspx
This article shows how to get the IP address of the virtual machine,but I want to know if I can change the IP by WMI or other methods.

Hiding the Hyper-V Failover Cluster Quick Migration Option
We have a 4 node Hyper-V 2012 (core) Cluster managed by SCVMM 2012. From time to time we have issues with SCVMM 2012 and our Engineers will use Failover Cluster Manager to manage VMs. This occurs the most when patches are released and we are migrating all of the VMs around to patch the Hyper-V nodes.
One of my frustrations with Failover Cluster Manager is the fact that the Live Migration and Quick Migration options are right next to each other in the context menu of a VM. We have had a few instances where an Engineer accidentally selected Quick Migration causing an outage in production. in one situation it caused database issues when a SQL node was paused and migrated using Quick Migration.
Is there some way to hide, remove or rename the Quick Migration option in the context menu? From time to time we may need it, but if I could hide or rename it, my stress levels would be much lower.

Why are my hyper-V network connections so slow?
Hello,
I have a Dell PowerEdge T620 with Intel I350 gigabit nics. The server and the nics have all the latest firmware and drivers.
I have each VM on its own dedicated network Virtual switch so there is a quad nic in the server and each VM has a dedicated nic.
The VMs say they are connected at 10Gbit.
When I try to copy between 2012 servers (VM to VM or VM to Host) the fastest I get is about 50 MB/s
When I try to copy between 2012 and a 2003 VM to VM I get about 2 MB/s. The 2003 server has the latest integration services installed).
I have only IPV4 enabled. We are not using IPV6 so it is disabled.
The server that they are on has VERY fast arrays (two RAID 50 - different controllers). If I copy from one array to another I can see about 500 plus MB/s

how to enable hyper-v roles on a virutal server 2012
Is there anyway to enable hyper-v role on a virutal 2012 server? I understand that I cannot run a vm on a vm, but I don't need, too. I just need to enable the role for studying.
I am able to run hyper-v 2012 core server (downloaded from MS) and use Hyper-V Managment tool on my windows 7 box to manage it, but this core hyper-v has limited features and I cannot enable the graphic GUI. I use powershell below
install-windowsfeature server-gui-shell
install-windowsfeature server-gui-mgmt-infra
None of ps work, it says no such command "install-windowsfeature"
I may miss syntax somewhere? Thanks.

Import Exported VM
Hi,
I hope I can find answer here. I am using Windows Server 2008 R2 X64 Enterprise. I exported 3 VMs ( they were all valid and working). After I reinstall the host machine and try to import VMs back. I got following error.
Import file format error: D:\Misc\VM Backup\UDAD\UDAD01\Virtual Machines\09DABA3F-65A7-481D-B836-68BC755DE5EF.exp.
I searched internet and find article http://support.microsoft.com/kb/968968, searched ScopeOfResidence in .exp file, but I could not find any values. 2 questions
1. How can I import them?
2. If I have no way to import them, how can I use virtual drives in the export folder to build the machine without losing information in the virtual hard drive. One of my VM has snapshot, How can I get it work.
Any answer will be much appreciated.

Werid Behavior--Cannot import a Ws2008R2 Exported VM into a Ws2012 Hyper-V
I have an exported VH that was made on an Ws2008R2 and I can import it 100% fine into a Similar WS2008R2 Hyper-V environment.
When I try to do the same with a fresh Export from Ws2008R2 into a Ws2012 Hyper-V I get this error " No Virtual machines files found"...
See attached Screenshot...
appreciate any advise on how to troubleshoot this...?
Again, the VM can be 100% success on a similar Ws2008R2 Hyper-V environment. Cannot do a similar import on WS20012 due to the error below.
I can however do a New virtual machine, and point it the *..VHD and that works, but I'm not looking for a work-around, I need to be able to do a clean "import", so all the previous config settings are properly "Restored.
TIA

Hyper-V VM Generation 2 - How to boot from .ISO
Hi guys,
Server OS: Windows Server 2012 R2
I have a VM Gen2 with following settings:
I can boot fine from the same .iso from a Gen1 VM so the .iso is bootable.
I know that the Gen2 VM uses SCSI instead of IDE, but I have no clue regarding how to boot from the .iso..
Any ideas?
Thanks in advance!

Hyper-V different Domain usage for RD Virtualization Host
Hi,
we have 2 AD-Domains (2012-R2):
management.local and production.local. Our Hyper-V Failover-Cluster (3 phys. machines) is placed in management.local. Our Remote-Desktop-Services are placed in production.local (Connection Broker, RD-Session-Host, ...).
We would like to add our Hyper-V-Failover-Cluster Machines as RD Virtualizations-Hosts to our production.local-RD-Environment.
Is that possible? No trusts between production.local and managment.local.
thanks in advance,

Failed to create the backup of virtual machine
Hi to all sysadmins.
I'm no expert in MS Windows systems and i need help fixing backup issues.
We have two physical machines running Windows Server 2008 R2 Enterprise SP1 as a Hyper-V host for three virtual machines each - domain controller, exchange server, file server, also running Windows Server 2008 R2 Enterprise SP1.
The problem is, since september weekly backups fail each time, on both machines.
Backup is configured as task scheduler job:
WBADMIN START BACKUP -backupTarget:e: -include:D:\vms -vssFull -quiet
Where E is backup disk (155GB free of 600GB), and D:\vms is location, where virtual hard disks and virtual machines are stored.
Backup used to work properly for several weeks. Windows Server Backup shows 24 number of copies, latest available from 28-09-2013.
I do have registered vss writer:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\WindowsServerBackup\Application Support\{66841CD4-6DED-4F4B-8F17-FD23F8DDC3DE}]"Application Identifier"="Hyper-V"Running vssadmin list writers gives me:
Writer name: 'Microsoft Hyper-V VSS Writer'
Writer Id: {66841cd4-6ded-4f4b-8f17-fd23f8ddc3de}
Writer Instance Id: {91a24129-d7fe-4539-98e6-ed008610873a}
State: [5] Waiting for completion
Last error: Retryable error
Following errors occur in event viewer:
Event ID: 10107 (warning)
One or more physical disks are attached to virtual machine 'slx-lu-ex1'. Back up programs that use the Hyper-V VSS writer cannot back up volumes that are attached to virtual machines as physical disks. To avoid potential data loss, use another method to back up the data on the physical disks. If you restore the data on this virtual machine, make sure to check the data of the physical disk for integrity. (Virtual machine ID E7B82301-709C-4002-874C-C235DFB3C71A)
Event ID: 10102 (error)
Failed to create the backup of virtual machine 'slx-lu-fs1'. (Virtual machine ID B1CC6FA8-824D-4E95-AF06-27E3164182EA)
And finally Event ID 521
The backup operation that started at '2013-11-09T22:30:11.707000000Z' has failed because the Volume Shadow Copy Service operation to create a shadow copy of the volumes being backed up failed with following error code '2155348129'. Please review the event details for a solution, and then rerun the backup operation once the issue is resolved.
Also, i'm not the person who configured whole thing, so please advice if it is the proper way of making backups.
According to event ID 10107, machine slx-lu-ex1 does have connected three phisical drives with exchange databases, logs and journaling, but there disks were mounted since beginning.

2012 R2 Hyper-V Cluster advice (Newbie to clusters)
I'm looking for some advice on our first Hyper-V Cluster. We have a new Dell VRTX server with two server blades (M520's), each server has 2 NIC's (1Gb) plus I have installed 2 x quad NIC's in the PCI slots and assigned one NIC to each server.
The VRTX uses shared storage which is managed by the chassis and appears as local drives. With the PERC controller driver installed its designed to work with clusters.
I need some general advice on configuration and setup.
This is what I want to achieve (Please excuse any stupid questions as this is the first time I've done clustering!)
Host Server 01 - Server 2012 R2 installed on RAID 1 local drives
Host Server 02 - Server 2012 R2 installed on RAID 1 local drives
Hyper-V role installed on both, cluster role also installed.
I was planning on Teaming the quad port NIC together for each server to give 4Gb links. (Cisco switches are configured ready for this)
I plan on creating a cluster and then hosting my Windows Server VM's on the cluster. Configured to fail-over to the other cluster host in the event that the one fails for any reason.
Do I need to create a virtual switch for the Team that the VM's can then use? Does this need a static IP?
Would I also configure one of the built-in NIC's with a static IP for managing the host?
I've created a Quorum drive that's 600Mb in size and available to both servers.
Do I also need a CSV drive available to both to store the VM's on?
If one of the VM's is a File Server, where would the data reside? in the FS VM or somewhere else? (Do I need to take this into account when sizing the CSV if that's where the VHDX file will reside...)
Thanks in advance for any support or advice :)
