Two questions about the maintenance of the VMs.
1.- If you run the OPTIMIZE-VHD is it necessary to run the SDelete previously?
2.-I have noticed difference compaction run the OPTIMIZE-VHD and perform through the console's HyperV. Any ideas?
Thanks!!!
Is there any way to connect to hyper-v server from WMIC?
any query?
This happens on two Windows Server 2012 Standard machines. When they are rebooted none of the Hyper-V based virtual machines start on their own despite being set to do so. All of them are set to auto start at boot and all of them have to be manually started when the host is rebooted.
I've looked through all other settings and cannot find another place to change startup settings.
Note that I've set a startup delay on all VM's but that didn't seem to do the trick.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!
Best regards,

I'm running a Windows 2012 Server and created a Windows 7 home virtual machine on it. Whenever the virtual machine boots up it will not recognize the network adapter and cannot connect to the internet. The host machine connects just fine. I've also created a virtual switch and double checked the settings for the Virtual Machine and the switch is selected as the network adapter. I don't know why it's not working.
Side note: I tried this earlier with a copy of Windows 7 pro as a test run and everything worked like a charm but I didn't have a extra license so I deleted it and created this one.
Hi All
there is is DHCP guard in VMs , what I understand this feature is used to drops dhcp messages from unauthorized virtual machine pretending to be a dhcp servers...
the question is : how a client knows that server is not authorized and will not listen to it ?
for example: if I have a VMs with DHCP guard enabled ..with a dHCp server called SERver1... another VM called VM-1 create a dhcp server
now a VM in the same network with SErver1 and VM-1 how it will decide to receive IP from Server 1 ?
regards
I am on a Windows 10 Enterprise PC with Hyper-V. I had setup a guest machine with Windows XP and managed to install the Hyper-V Integration Services on the guest PC and turned on all options in the Settings. The problem I have is that everytime I click on the screen I have to do the "Ctrl+Alt+Left Arrow" Combo to release the mouse from the guest machine screen.
I would like to know how can I fix this. I know it can be done since the image I had previously downloaded from modern.ie allows seamless click in and out of the window.
Hello.
I am running a physical server w/ 2012 R2 Datacenter. All updates have been applied as of 12/23/2015.
I have several VMs running under Hyper-V. Some are Win7, one is Win 8.1, and one is now Win10.
I frequently change the DPI settings of the virtual machines via a console session from the Hyper-V Manager in 2012 R2. This works OK for Win7 and Win8.1: after I change the DPI in a Hyper-V console session, users connect via RDP and the DPI change
seems to be preserved most of the time. Sometimes the DPI magically resets itself and then, if the user is over the age of 50, they call me for a DPI reset. I was hoping Win10 would solve this "mystery DPI reset" problem once and for
all.
But when I connect to the Win10 VM via a Hyper-V console session, I don't see a simple DPI setting anymore. Instead there is a slider that taunts: "Change the size of text, apps, and other items:" but I cannot slide it because, even though this is a console session, I see the dreaded text "The display settings can't be changed from a remote session." This is NOT a remote session - this is a CONSOLE session.
Any help or insight would be greatly appreciated.
Hi,
I have a Hyper-V VM. This is set to a VLAN of 2 and given a valid network connection. Likewise with the Hyper-V Virtual Network Manager, there is a VLAN of 2, valid connection, etc.
However, I can't ping the Hyper-V VM from the Hyper-V server (they're in the same domain etc). The result of the ping is always "Destination host unreachable". The VM has a valid IP and DNS entry. I also can't ping from my physical workstation but this is on another domain (does that matter?).
Thanks
Is it possible to use a VM in parallel with the host, simultaneously, by two different users on the same physical machine?
I got to the point where I have a working VM with Windows 10(the host also uses windows 10). I want to use two sets of mice & keyboards separately, one on the VM and another on the host.
Is it possible to assign a usb port only to the VM?
Hello!
I installed an Hyper-V 2012 core with two VM.
The hypervisor is on an 4TB raid and there are two other 1TB raid for backups, snapshots etc.
I saw, that the(4TB) drive was unexpected small (2TB) and via diskpart and a look into the BIOS settings i saw that everything was in legacy/BIOS mode.
I tried to Reinstall the Hyper-V in uefi and hoped that i only have to delete C:, but in the setup of the Hyper-V there where no disks shown, even in diskpart at the repair options.
Whats options do i have now? I need the full disk space, because one vm ist quite big.
Thank you in advance!
Ok, so i have a little Problem with my VMQ Configuration, maybe someone can help me out.
So here it goes, I have:
- 2 CPUs with 18 cores each, HT enabled with gives me 72 logical cores.
- 2 Teams of 2 NICs each in switch independend, dynamic mode.
This is how my current VMQ settings look like:
as you can see, VMs are getting queues.
However, after a restart of the host i get this error in eventvwr:
event id 106, source Hyper-V-VmSwitch
"Available processor sets of the underlying physical NICs belonging to the LBFO team NIC /DEVICE/{74800110-A2A6-4FA7-8582-3C95336CAF72} (Friendly Name: Microsoft Network Adapter Multiplexor Driver #2) on switch 6AF906EE-8945-46E3-B75A-02DCB43D54AC (Friendly
Name: converged_net_vSwitch_10Gb) are not configured correctly. Reason:
The processor sets overlap when LBFO is configured with sum-queue mode."
I get this error for both Team Adapters.
Someone can show me what im doing wrong with the configuration? I dont see them overlapping..
Hello good people of Technet!
I'm having a problem with my Hyper-V Failover cluster and I was hoping someone could help me out...
Please bear with me, as I have had to figure Hyper-V out for myself mostly, I will happily provide any missing information.
To start off, I have set up the following Failover cluster:
Operating System: Hyper-V Server 2012r2 Core edition, Note: Not Server 2012r2, but Hyper-V Server 2012r2.
Number of nodes in the cluster: 2
Number of physical NICs in use on each host: 8
Storage: Dell Equallogic SAN
Storage access: iSCSI
Port Configuration: 2x iSCSI in a NIC Team
4x Virtual switch, each for a different IP range, not shared with the host OS
1x Management NIC, connecting straight into the main LAN
1x Heartbeat NIC
Between the hosts and the SAN are two switches which we wish to separate from the LAN to isolate the traffic on the cluster and traffic from the cluster to the SAN from the main LAN for security reasons and to comply with Microsoft best practices.
The aim is to make the Hyper-V nodes only accessible via the Management NICs from the main LAN.
The following NICs have connections into the LAN:
1x Management NIC on each server
1x Virtual switch providing LAN access for guest VMs on each server, switch is not shared with Management OS.
All other NICs are connected into the switches, and the switches themselves are currently connected to the LAN by a single connection each.
The problem: When the LAN network cable is pulled from the switches in an attempt to isolate traffic, the Hyper-V guest interface for VMs becomes unbearably slow, as if it's having severe network routing issues (a guess). Also, the traffic from one particular
DMZ subnet (possibly all, but this one's the most problematic) will not route properly to another machine on the same subnet, and communication is lost for these particular guest VMs.
Would anyone have any ideas how I might be able to fix this?
I do apologise if this question seems oddly phrased and vague, I'm fairly new to Hyper-V and as mentioned earlier, I would be happy to provide any additional information.
Many thanks,

Hi,
I am very new to Hyper-V so please forgive me if I am asking this in the wrong place.
I installed the Windows 2012 Data Center Edition 6-month trial version, set it up with the Hyper-V role and configured three virtual machines. I decided I wanted to test the Free version of Hyper-V instead so I exported each of those machines to an extra hard drive I installed in my test machine. It only took a few minutes to export each machine.
I then proceeded to install the Hyper-V 2012 Free version in place of Windows 2012 Data Center Edition and have the Hyper-V manager installed and running on a Windows 8 machine I have in my lab. I am able to run the Hyper-V manager and connect to my new server just fine. However, when I attempt to import one of the three machines I had exported previously it starts the process fine, eventually a small window pops up that says "Preparing virtual hard disk destination..." and it seems to be hanging there, even though it only took a few minutes to export this machine it has been stuck on this window for over an hour now.
Does anyone have any idea how to troubleshoot this issue? Or is it normal for this process to take far longer than the initial export?
I appreciate any insight anyone can provide.
Thanks in advance.
I have a Hyper V 2012 DC failover Cluster with about 30 Servers operating on it. A problem arose the other day with where one of the servers changed their mac address. There was licensed software on that server that apparently bound to the MAC address. We of course did not know this at the time, but now the software is unusable the license agreement says you can't transfer the license to a new machine. Tech Support said we would have to purchase another $1K license due to this. Is there a way to go into Windows and find out what the old Mac Address was? I would have to think that Windows would log the issuance of Mac Addresses in Hyper V...especially since it tends to change them all the time. I have looked for hours and can't find anything with the old Mac Address, only the new one.
I would love to know if this is possible, or if I need to bite the bullet on this one and spend the 1K and this time give it a static MAC and keep a good record. Sucks as the tech installing the software never mentioned that the license was hardware or Mac address bound.
Hello,
I'm having an issue where on two of my newly built Hyper-V hosts, guest VMs cannot see the network. I have been able to successfully deploy the hosts using WDS. When I attempt to deploy the guests using WDS, they cannot see the WDS server. I was able to successfully deploy guests using SCVMM, but when run the guests did not have internet access (could not contact DHCP to get an IP address).
I've tried troubleshooting including redeploying the host (both from my capture, and bare from the original installation media) and have ensured it is up to date on Windows Updates. I've tried to find references online of people with the same problem, but their troubleshooting did not help me (my virtual switches appear to be configured correctly the best that I can tell).
The configuration I'm providing below is with two physical network adapters on the host, one connected and one disconnected. I've created an external virtual switch for each, and a virtual network adapter in the guest for each virtual switch.
When I try and PXE boot the guest, it attempts and times out on both virtual network adapters.
Hi all, I have turned on hyper-v in windows 10 then pulled up hyper-v manager, tried to connect to local server. received an error message about component services, to check if it was running and it was not so i started it up. my question is can hyper-v be run in widows 10.
