I just turned on my Hyper-V, but the screen is completely black.

I can still connect to the different Remote Desktops i have on it, and I can find it by pinging it, but I can't do anything on it directly.

Is there something wrong with it?

please help!

After finding out how to share files and folders between the host and guest operating systems (both Windows Server 2012 R2) through virtual switches, and reading some tutorials online on how to do this, I had created two virtual switches for my guest OS.  One is an external switch (vNET) using my Ethernet connection and the other is an internal switch (vLAN) that has no internet connection and I planned to use to be able to file share between the guest and host OSes.  These have been configured inHyper-V's Virtual Switch Manager, and specifically in the VM's settings too.

However, I've realised that even when vLAN is disabled, vNET is still able to access the network shares, meaning these are publicly visible.

Is there a way I can make network shares only accessible when vLAN is enabled?  I want the internal switch to only be responsible for internal network traffic that shouldn't be visible externally. 

I have a software I install it on real HDD - ok

but

when I trying to install it on VM not install because it want to read the serial number of HDD till even use the physical HDD on VM.

is there any way to make virtual HDD look like real HDD or change the serial of it? (not a volume ID)

I'm trying to create a new VDI pooled image collection using a Windows 7 virtual machine created in SCVMM but VDI no longer sees that virtual machine in the list of virtual machines after I did a sysprep.  One thing I noticed is that I'm unable to use the /mode:vm command in sysprep even after I installed the integration services from Hyper-V when I could swear that it worked just fine on a different VM just yesterday.

I'm honestly not sure that's my problem, I can't find anything online that says when creating a Windows 7 VM for VDI that you NEED to use the /mode:vm command, but I know when it worked on one VM I created I didn't have any problems and was able to create the VM without an issue.

So to summarize, I'm confused on two fronts, do I actually need to use the /mode:vm switch?  And if so why doesn't that work even after installing all windows updates and integration services from Hyper-V?

I'm on a huge time crunch so any assistance would be greatly appreciated.

Hey Guys

Sorry if is a dumb question or there is already a builtin solution for this.

But im looking for a tool, script or something to export my Hyper-V configuration (with hosts, vms, virtual switches) to a visio diagram. The more automated better.

there is such a thing?

Thanks

Hello,

When we use use either Windows RE or a third party image based full system restore into a Guest VM, the data transfer speed is painfully slow. we're talking over an hour for 52GB when it should be around 10 minutes!

here is the setup:

Server 2008 R2 hyper-v

broadcom netextreme ll 1Gbps network adapter - this connects to an iSCSI target which holds the recovery images, the iSCSI target resides on a NAS which has several disks in RAID 0 and also has 1Gbps network adapter. the transfer speed achieved to and from the Host (local disks) and NAS is getting around 100MBps, approx 80-90% of the 1Gbps adapter. this is fairly decent performance for us. the disks in the server and NAS achieve much higher than 160MBps.

second broadcom netextreme ll 1Gbps network adapter which assigned to the virtual switch, and shared with the management adapter - again, transfer speeds using this adapter on the host to the NAS is the same as the other one. the virtual machine's OS VHD file exists on a seperate iSCSI target which is on a seperate physical NAS (performance from host to NAS is fine at around 100MBps)

i offline the iSCSI target so I can attach it to the SCSI controller of the VM guest, i start the guest and perform a recovery, the data transfer speed was around 5MBps regardless of restoring a windows image or a third party image, this is nowhere near what I am expecting.

i enabled flow control on both adapters and the performance has gone up to around 10-15MBps, sometimes spiking at about 20MBps, this is still a long way off what I am expecting.

I believe this has to do with the network adapter on the hyper-v host, there must be a setting which needs adjusting but I am unsure what. if I am looking at transfer speeds to all the locations involved, I am easily getting 80MBps -110MBps depending on what I am transferring to and from various locations, so I am expecting a recovery speed within the VM guest of going a minimum of 80MBps, preferably 100MBps really.

any ideas? many thanks

Hi,

I'm new to Virtual machines.

Once the snapshots have been deleted and merged in HyperV they free up  free up disk space and all other snapshots are now in a single compact VHD, and the performance increases.  Does that mean this single snapshot will build up again in the future and cause the system to slow down? 

Thank you,

Hello,

I have two Windows 2008 x64 servers, running Hyper-V.  I have about 15 VM's on each server.  I manage the VM's all through the Hyper-V Manager.  When I try to connect to Hyper-V Manager and manage my VM's I get "Connecting to Virtual Machine Management Service."  This times out after a few minutes and then the Hyper-V Manager displays:  The operation on computer 'localhost' failed.

This happens about 2-3 weeks after a reboot.  The only fix I have found is to reboot the server, but since these are production servers this is kind of a pain.

Hi!

Is it possible to connect to windows 2008 hyper-v servers through windows 8.1 console? I am getting "This version of hyper-v manager cannot be used to manage servers running hyper-v in windows 2008 or 2008 R2?

Thanks.

I have successfully setup cert based replication between 2 of my clusters on different domains.

I have noticed that the replicated VM's don't have anything selected in the Virtual Switch. How do I get it to pick up the virtual switch based on name? Both clusters have both an "external" and "internal" virtual switch and the VM's (140 of them) have a varying combination of virtual nic's connected to these 2 virtual switches.

I've been trying to get windows phone 8 emulator working with no luck. This lead me to find out that it's not emulator problem, but hyper-v itself. I installed new VM and when starting it, I'm getting the following error after it attempting to start for about 5 minutes:
"Name" failed to start worker process: Server execution failed (0x80080005)
I've checked cpuid for compatibility with virtualization (vmplayer works ok)

I don't see anything in windows event log, but Hper-V-Worker/Admin log has the following entry:
The Virtual Machine Worker Process has lost its connection to the root\virtualization WMI namespace: General access denied error (0x80070005). As a result, some WMI operations may not function correctly. To correct the problem, try restarting the Windows Management Instrumentation service.

and Hyper-V-VMMS has the same message as above about worker process not starting.

I've tried re-reinstalling hyper-V with no success.

Thanks for any help.

Hi,

I am familiar with the VMWare products - Player, Workstation and ESXI and want to know what the Microsoft equivalents are. The host will be either Windows 7,8, 2012 and the guests will also be those. I am looking into producing VM's to help with product evaluations and development.

I have heard about Hyper-V but I don't understand if this is a client or server system.

Can some explain what are the equivalents of VMWare Workstation, Player and ESXI?

Thanks

So I got two new servers a Dell R620 and a R720 running Hyper-V on Windows 2012 R2 all clients on them are 2012 or 2012 R2.

All NICs are Broadcom NetXtreme, 2 quad port per server, I am currently running 15.6.0.10 drivers with 7.6.15 firmware on the R720 and 16.2.0.4 drivers and 7.8.16 firmware on the R620. No guest NICs are teamed.

In the last 2 weeks I had two guest NICs in hyper-v (with a few days between) on the R620 and 1 on the R720 fail to a point where the NIC cant communicate with the network, getting a 169.x.x.x IP address. I delete the NIC in the Virtual Switch Manager, re-add it and everything is fine again. I don't allow the managing OS to share the network adapter, for the most part, I use 1 NIC per VM.

I recall this happening back with Hyper-V 2008 R2 as well, but generally at the time of a driver update or some sort of change. These Hyper-V hosts have no received any drivers, firmware or Microsoft updates anywhere around the time of these failures.

Any ideas?

Hello All,

I want to expand a 'C:\' boot parition on the VHD [running WIN2008R2].

I see a standard warning message that says - do not edit a virtual hard disk associated with VM that has snapshots.

When I go to the location of this VM (on the CSV volume) , I see two hard disk files.

ABC.VHD

&

ABC_2bas9393_12-32-30-blah-blah.AVHD.

My question is - How do I expand the drive ?

Should I delete all the snapshots and then expand the disk ? [Will I loose all the changes that were made since the begining]

or,

Do I need to first merge .avhd with .vhd ? [what exactly this does ?]

My objective is to - Expand the drive & keep all the snapshosts.

Thanks,

-Ashwin

HI all.

New install of 2008R2 on HP DL-380 G6.  I have created (several) VM's none of which will start.  If I remove the IDE Hard Disk and add a DVD of the OS ISO, it will boot and start the install (although with no HDD). 

It seems like the IDE controller is working ok - it is what the DVD drive is using, but it cannot mount a VHD.  The error indicates a driver is not working (although the DVD on IDE works fine) so something to do with VHD?  I can attach the VHD in disk management, so it does not seem corrupt - again I have tried with both dynamic and fixed VHDs.

Full error is:

I am having difficulty using Hyper-V client on a Dell Precision T5500 Workstation running Windows 8.1. The workstation has 2 Intel Xeon E5506 processors and 12 GB Ram. I have verified that the processors are SLAT-capable.

I have followed the instructions to enable Hyper-V on Windows 8.1. I have restarted my machine several times since I enabled Hyper-V.

When I look at the “Apps by name” screen it shows two Hyper-V management tools: Hyper-V Manager and Hyper-V Virtual Machine Connection. Neither tool allows me to create a new virtual machine. The Hyper-V Manager gives me only one action: Connect to Server. If I connect to the server on my local machine, the only action it gives me is “Remove Server”. In the Virtual Machines box, it has an error message: “Hyper-V encountered an error trying to access an object on computer “localhost” because the object was not found. The object might have been deleted or you might not have permission to perform the task. Verify that the Virtual Machine Management service on the computer is running. …” (I did try running it as administrator with the same results.)

Not only is the Virtual Machine Management Service not running, it is not even listed among the services available. There are 7 Hyper-V services available, but they all look like subordinate services. I tried to start several of these services manually, but they stopped immediately because they were not used. Any idea how to get Hyper-V working?

I'm a little new at this, so bare with me. What I'm looking to do is push Hyper-V Windows 8.1 workstations down to a physical workstation. I understand you can do some of this through RDS, however I'm looking for permanent desktops instead of temporary. I have a 2012 R2 env. along with MDOP, SCCM, and SCVMM.

Is there any documentation/videos out there that can guide me in the right direction on what I'm looking to do. Thanks!

I can RDP into a Hyper-V 2012 R2 server across the local LAN with no problem.

However I'm getting a black screen and timeout disconnect when trying to RDP into the same server across Hamachi VPN. The clients connects and I can authenticate. The active LAN session is terminated after authentication, but the session never fully loads at the remote client.

Inbound firewall rules are identical; outbound rules are set to Allow. In fact I disabled the firewall completely on Server5, but didn't see any improvement.

Here's the basic summary:

Server1: Hyper-V 2012

• Workgroup mode (same workgroup)
• Can RDP through local LAN, Win8.0 client
• Can RDP through Hamachi VPN, Win8.1 client

Server5: Hyper-V 2012 R2

• Workgroup mode (same workgroup)
• Can RDP through local LAN, Win8.0 client
• Can not RDP through Hamachi VPN, Win8.1 client

On Server5 I'm getting this Information-level entry in the Application event for the VPN connection, but not for the LAN connection:
