I have installed two virtual machines(win2k3 32bit and win2k3 64bit ) on Windows Server 2008 RC1 With Hyper-V Technologies (Beta) enterprise. Mouse is getting lost inside VM (using CTRL+ ATL +  LEFT ARROW  comes mouse control control in host OS).

Is there any setting to make mouse works? Insert Integration Serice setup Disk operation succeeds.

I need some recommendations for configuring the hard drive layout when installing Hyper-V Server 2008 RTM (the stand-alone install, not the full Server 2008 or Server Core).

I have a Dell PowerEdge 2950 with 2 Quad processors, RAID card, 6 x 750 GB hard drives, and 32 GB RAM.

When I first thought about setting up the machine, ideally I just want 2 partitions: the parent partition holding the Hyper-V OS install, and then everything else on a large, second partition (VHD's, snapshots, config files, etc.).  Each new VM would just get its own folder.  All of this would physically sit on one huge RAID 5 array using all 6 drives.

The problem is the amount of storage I have.  If I create one large RAID 5 array, it gives me 3.5 TB of disk space.  Then, when I go to install Hyper-V server, it doesn't see one 3.5 TB drive, it breaks it up into one 2.0 TB drive and one 1.5 TB drive.  Is this because there is a 2 TB NTFS partition size limit?  Also, is having one huge RAID 5 array optimal regarding disk contention and reads/writes?

So, basically, my question is: what would be the recommended/best way to divide up the disks I have (6 x 750 GB drives) both physically using RAID 5 as well as logically using partitions?

I initially wanted to set up a 100GB Hyper-V parent partition, and then try to allocate all of the remaining space (~3.4 TB) as a single large partition, but it won't let me do it (again, the 2 TB limit, I think?).

Would dynamic disks/volumes help?

I looked at a bunch of Microsoft documentation on Hyper-V, but none of it seems to address these issues (best practices for partitioning and setting up the actual host server itself).  Does any best practices documentation like this exist yet?


Sorry - I know that is a lot to ask in a single post :)  Any advice would be appreciated.


Thanks in advance.

Have a Windows 2012 Standard Sever with Hyper-v Installed.

Server has dual broadcom Nic and the broadcom Manager.

Virtuals are

Windows Server 2008 Ent ( Eval image with Sp1) 

Windows 7 pro Sp1

none of them can connect to external network

I have re set the new Drivers for the broadcom card and remove and re installed-created the Virtual Switch 

i have only 1 connection so not even teamed up right now. Vary basic.

I can ping the Local Hyper-v Server  and the Hyper-V can ping the Virtual but i can't get out of the server. None of the Threads on the forums seams to work for me.

Very Frustrated, a the moment. This is my test environment and I'm starting to think on Vmware the more this doesn't worl.

please HELP!!

Hello

i have had a strange issue on some 2012R2 VM's (gen2) running on Hyper-V 2012R2, managed via VMM.

The LAN connection inside the VM is suddenly missing, (no the VM has not been migrated)
i can't find anything in the event log on the host or on the VM.

i look like this:

in some cases device manager look's like this:

the issue have occurred on 10-15 vm'es out of 700, and only on 2012R2 not on 2003/2008/2008R2/2012

The VM is still accessible on the network, but the VM itself is not able to reach any resources.

The fix is to uninstall the nic inn device manager, search for new hardware, and reconfigure the IP.

Thank you!

Hi,

In my environment I have 2 Hyper V Hosts, with 2 VM's on Hyper V1, we have configured replication to Hyp V2 Server. Currently both Servers from V1 are replicated to V2 with replication health showing as normal.
We have checked and tested the failover and confirmed as successful. The planned failover is working fine for the Server. But when I try to perform the  'reverse replication direction after failover' its getting failed at the step 'reverse replication direction'. 

As a troubleshooting method we performed the below:
-The replication and planned failover is working fine
-Changed the SPN in AD under machine attributes, so as to communicate with Hyper V hosts
-Confirmed proper communications/ping as available  
-Confirmed the port 80 as opened on both Hyper V hosts
-Port 443 currently closed (do we need to open?)
-Modified the hosts file and added the information of both Hyper V hosts on both Servers

-We have also turned off the Firewall on both Hyper V host Servers and tried the same but still the issue persists

Our previous scenario was like the below:

Initially both Hyper V Host Servers were in workgroup and we faced similar issue while configuring replication.
Hence we have added the same to our domain that is domain.local. Also checked and confirmed that "Primary DNS suffix of this computer" check box as checked.

A quick response is much appreciated, Thank you !!!!!!

I have a Hyper-V Server Core 2012 in a workgroup environment and uses Hyper-V Manager in Windows 8.1 to manage my Hyper-V server.  It was working previously and when I try to connect to it today (it has been a month or two since I last connected to the server using Hyper-V Manager), I got the following error message within Hyper-V Manager: "Access Denied.  Unable to establish communication between '<server name>' and '<win8 computer name>'.  

I had the same problem when I set it up initially but was able to get it to work by changing the access permission using DCOMCNFG.  

What I also realized is when I right click on the Server node on the left pane, the Hyper-V Settings and Inspect Disk option seem to work.

Does anyone has the same issue and had a solution?

Thanks!

I have a desktop setup to remotely manage Hyper-V and it is working fine.

I am trying to setup remote management from my laptop.

The server is failing to ping the laptop using IPV6.

The desktop can ping both the server an the laptop using names and IPV6 option -6

The laptop can ping the desktop and the Hyper-V server using name and IPV6 option -6

Hyper-V server can ping the desktop, but not the laptop using IPV6 option -6  

Everything works fine with IPV4 .

I have checked and rechecked the Hyper-V server Host table and it has what appears to be correct issues for both the desktop and the laptop.

Any other thoughts on what to check?

Thanks!

I have created VHD of Windows Server 2012 and I boot it in Windows Server 2008 r2 hyper-v but it only have black screen.

I have already install the update where suggest by Microsoft that for boot Windows Server 2012 VHD in Windows Server 2008 r2 hyper-v but still not working.

how can solve this problem? please help me! thanks a lot.

have installed windows 2012 R2,  all have been working fine and installed a Hyper-v server which am have install AD, DNS, DHCP which has been working grate.

after install an update on virtual server I rebooted and now am receiving a BSOD system_thread_excption_not_handled (WppRecorder.sys)

and it not allowing me to access anything. 

I have look into the firmware setting on the virtual server  and noticed file type called bootmgfw.efi on the firmware virtual setting.  which details 

Description: Windows Boot Manager

Value: \HD(2,GPTBA6F9016-9039-4EED-95D7-7C9DFDA947F4,77056,66560)\EFI\Microsoft\Boot\bootmgfw.efi

am using a physical hard disk which I have created using virtual disks which is offline and I have other Hyper-v Virtual server which are using the same settings and it working fine.

can anyone help me with this issue?

Many thanks,

I'm trying to get remotefx with hyper-v to work so I can occasionally play from work and so that I can let a bunch of us (me and some friends) play league together when they're at my place without them always needing to bring over their computers

Right now I can't seem to get remotefx to run league of legends at all, I've successfully loaded remotefx onto a windows 8 enterprise guest and installed league of legends and direct x on it, but as soon as the game loads it doesn't even go passed 1 fps.

On the same windows 8 enterprise guest with remotefx I am getting a lot of 80 fps in 3dmark11 tests, so this seems really weird.

The host is using windows server 2012 r2 with gtx 780 and latest video driver installed, guest is windows 8.1 enterprise with remotefx enabled

I've read someone playing league of legends using remotefx in a windows 2008 server from their work, I've tried contacting him but he hasn't responded since I guess he's no longer active on that community where I asked

Hi,

another post with more or less the same issue as numerous other posts, for example:

Mentioned post were of no heklp though. In this setup I have 2 2012R2 Hyper-V boxes in a Failover Cluster and a HP MSA2040 SAN. Within this cluster I have 2 2012R2 guests that are also clustered. They have 2 Synthetic Fibre Channel Adapters, each one connected to another physical port on the host. Quick Migration works any time, Live Migration only once in a while. I get messages like:

'<GuestOS>' Synthetic FibreChannel Port: Failed to finish reserving resources with Error 'Unspecified error' (0x80004005). (Virtual machine ID 8AABB243-7333-4729-A060-120EF8E993A7)

Facts:

• Basic stuff like NPIV support is ofcourse enabled and all HBA's and switches support this;
• MPIO is setup accordingly to HP recommendations;
• The hosts have 2 fibre ports each connected to a seperate fibre switch;
• Guest VM's have 2 Fibre Adapters, each connected to a seperate Virtual SAN;
• Initially I had all WWPN's defined in one host on the SAN, as per a recemondation in one of the mentioned threads I split that up and made a seperate host on the switch for each WWPN set. As the switch only cares about WWPN / WWNN's rather than the aliases they are 'bound' to this did not help;
• Virtual SAN's are equally setup on the hosts, and each matching Virtual SAN is connected to the same Fibre Switch so physical pathing should be ok;
• Zoning is correct; all 4 wwpn's are added to zoning and can access the luns (if not it would not work 'sometimes');
• When I start the live migration, the 'not-active-WWPN-set' is immediately presented at the switches and the switches see the respective WWPN's as active. At that point all 4 WWPN's of the guest are active according to my switches. The switches also recognize these WWPN's as 'NPIV' WWPN's;
• When I stop the guest, and manually switch the addresses of set A and B over and start again, I see all my storage. This again to make sure zoning is ok and all storage is available on all 4 WWPN's;

Now the point of interest: The MSA2040 seems to be rather slow to recognize or 'discover' as HP calls it presented WWPN's. This is the same for physical hosts as well as virtual hosts. Sometimes it takes up to a minute or two before a host is actually discovered by the SAN. Then it presents the configured LUNs to it and that step again takes a while. I think this is the base issue here. When I do a live migration all 4 WWPN's are available but the storage only discovered 2 of them. At the sporadic times Live Migration DOES work, the SAN (ofcourse) discovered the WWPN's and as soon as the LUN's are presented to them, the migration immediately continues as expected.

The same happens when starting a guest with Synthetic Fibre Channel Adapters: Starting such VM immediately presents the WWPN's at switchlevel, then 'stalls' at 10% for about a minute and then continues booting. Sometimes the SAN discovers the WWPN's faster, and as soon as the LUN's are presented the booting continues and everything is ok. However most of the times the SAN is 'too slow' and after a timeout of a minute or so the VM continues booting. This results in the storage not being available in this guest until the SAN discovered the WWPN's.

The same happens with Quick Migration. With Quick Migration there is no requirement for the LUN's to be active and therefore it works. And again when the SAN is quick enough the storage is there immediately when the migration is done, when it's too slow the storage is not available after migration, until the SAN discovered the WWPN's again.

With Live Migration ofcourse there is a requirement that the LUNs are available to all 4 ports at time of migration. Unlike a quick-migration, Live Mgration will not continue when LUN's aren't available.

So I have 2 options here that I think would fix my issue:

• Have the SAN to pickup new presented hosts faster;
• Have Hyper-V to wait longer before a live migration times out.

The first is not an option, HP does not have any settings for this in the MSA2040 (and neither in the P2000 G3 which we have as backup as well in this setup).

So maybe we can increase the Hyper-V live-migration-wait-for-lun-timeout?

The concrete question:

Is there a regkey or something for increasing the 'waiting for storage' timeout on live-migration?

Ofcourse any other 'magical' solution to this issue is welcome :)

Hi Everyone,

It's been 2 days since remote users are unable to work remotely on the server as they used to. In fact, my compagny has 4 differents location in town. Each location has a physical server with Hyper-V Manager installed on it, and the servers are running Win Server 2008 r2. 

On the location that the Remote Desktop Server is based I realized that when various win 7 clients are connected remotely, it is almost impossible for anybody to work.

As I tried to troubleshoot the problem, I noticed that when I shutdown the virtual Server that is holding AD, DNS and DHCP everything come back to normally and when I restart it the network goes down once again.

Please I really need help, I am very desprate. Thanks in advance for all your support.

Best Regards 

Hi,

I'm having issue creating checkpoints for VMs. It was previously working fine until I got into issue trying to backup the server and its Hyper-V guests. Now, every time I try to create checkpoint, I'm getting,

"An error occurred while attempting to checkpoint selected virtual machine(s). Checkpoint operation failed".

Running,

PS E:\WindowsImageBackup> get-winevent -MaxEvents 10 -ProviderName "Microsoft-Windows-Hyper-V-VMMS"

I'm getting a lot of "Cannot load a checkpoint configuration: General access denied error (0x80070005)."

I'm checked file permission and I don't see any issue with file permission. I tried moving the configuration files, snapshots and etc to another path using the "Move" command and the issue retain. By doing so, it would create the folder with the correct permission.

Any help would be greatly appreciated.

Dear All,

I have one Hyper V server that is running Windows 2008 R2 Enterprise. This Hyper V is used for AD and CAS and mailbox of exchange server. I have built 3 VMs inside. For instance, VM1, VM2, and VM3. each of the VM has been given 100GB HDD size and all is fixed disk VHD. The HDD partition size that is used to store the VHD is 700GB size. Currently, each of the VM HDD utilization is less than 50%.

Now, this is the problem. currently, I have been monitoring the HDD size from the hyper v server. I found that though each of the VM is not really fully utilized, the partition that hold the VHD for the 3VMs is keep increasing. Currently it has taken over 600GB, though the total of the 3 VMs VHD size is just about 300GB. it is very strange. when I check on the properties to check the total size of the VHD folders inside the partition, It is shown that only 300 over GB being used.

Kindly advise me on what happen to the partition, which cause the size is keep growing.

thanks for your attention.

Regards,

Henry

Hi

I want to install elastix on Hyper-v 20082 but the following error appear :

"No Valid Devices were found on which to create new file system"

so there is any way to install elastix on Hyper-v 2008R2?

With Regards

I have a Server with Windows Server 2008 (NOT R2) running with the Hyper-V role installed and 8 VMs.

I want to move them to our new server running Hyper-V 2012 R2.

I tried to copy the original files to the 2012 Server and Import them as described in a similar article on this site (not allowed to post a link) but I get following error message (translated from German):

Error while importing.

The VM-Version of the virtual Maschine xxx could not be updated: unknown error 0x80004005

The VM-Version 1.0 of the virtual Maschine is not supported.

Any suggestons / ideas on how to fix this Problem?

Hi

the link here Hyper-v Config seems to indicate the creation of 1 virtual switch but has multiple virtual LANs attached to it. 

firstly, is this correct how I am understanding it?

secondly, I take it there is no way to do this in the GUI since I can't find it, is command line the only way to do this (not that I mind that at all)?

thanks

Steve

I have noticed in Hyper-V 2012R2 when migrating a VM around it leaves behind an empty folder structure. Is there a way cleaning this up automatically after the successful migration?

For instance,

VM located at C:\clusterstorage\FOLDER_A\VM

Moved to C:\clusterstorage\FOLDER_B\VM

But.... The FOLDER_A\VM still exists after a successful migration. This should be deleted to prevent confusion and allow a VM if migrated back to FOLDER_A to reside in a folder called VM and not VM_1.

hello guys

now we have win2k8 r2 with installed hyper-v role.

we had a network adapter with 4 ports and these 4 NICs was installed before adding hyper-v role so we select the these 4 NICs when installing the hyper-v role as usual.

after that, we add other new network adapter with 4 NICs.

the problem that we can't see the new 4 NICs in hyper-v manager to create external connection.

any suggestions ??
