Hyper-V is a native hypervisor; it can create virtual machines on x86-64 systems and supersedes Windows Virtual PC as the hardware virtualization component of the client editions of Windows NT. A server computer running Hyper-V can be configured to expose individual virtual machines to one or more networks. Hyper-V Server supports remote access via Remote Desktop Connection. Administration and configuration of the host OS and the guest virtual machines is generally done over the network.

Is there something I can do when I receive this error (op operating system was loaded) in Hyper-V

I do not know if the system I have imaged was UEFI or not. I also do not understand the SCSI disk term, since it is a regular SATA of which I created the VHD.

I am setting up windows server 2016 for the first time and wanted to know if I wanted to setup additional server AD, hyper-v, other servers to add to a domain etc, would I need to have a separate server for each (physical) or create them as I've seen in videos after installing the initial windows server 2016?

This is for a home production environment?
We have a pfSense 2.3.4 with LAN, WAN, DMZ.
In DMZ subnet, we set up a Network Load Balancing cluster with two web servers in a 2012R2 Hyper-V environment. Their IP are:
DMZ port:
NLB Cluster:
NLB mode: multicast

Inside the DMZ subnet, each host can ping other hosts without a problem. The only stumbling block is, from pfSense, I can NOT ping the NLB cluster even I am able to ping all other servers in DMZ subnet. As the result, the cluster is useless.

In pfSense, I can see there is no ARP table entry for this cluster IP. How come?

I bet the Hyper-V NLB cluster is not new and am wondering if anyone ran into this issue before. Please help.
I am having a probelm with using local usb printers redirected for RDP session. I install the usb printer on the WYSE thin client Win 7 Embedded. The printer works. I then login to the RDP VM using use local resources with RDP session. The redirected printer shows up in the list of printers in the Virtual Machine (Win 10 pro). When selected to print it does not and just gets an error.

I then tried to share the printer on the thin client. I can connect to the printer and install while in the RDP session. It all works fine but as soon as you restart the VM, Thin Client or just logout the printer stops connecting.

Any ideas on using local usb connected printers. While logged into the RDP VM session?
We have a Hyper V VM that is a server 2012R2 box. 64-bit with 4 GB of RAM.

It crashed from what I believe is a memory leak. Not sure how or the best way to monitor for this.

Ideas or experience?


Hi all,

I have an old machine which has server 2003 OS with VMware version Version 1.0.10. Yes, you read it right Version 1.0.10. This hosts an XP machine which has an oracle db on it.

Long story short, I have no admin pw's for the oracle db in order to shutdown cleanly and migrate to a new machine so I was wondering if anyone has been able to convert a VMware VM to a hyper-v machine.

On our new server we are running Win server 2012 R2 with hyper-v and would ideally like to migrate to this so I can backup, monitor and manage.

In an ideal world, I would love to be able to use something like Veeam to back up the XP machine, then restore but the version of Veeam (version 9), doesn't support server 2003.

Any suggestions?

I've inherited a HP server running 2 VM's.   The CPU appears very limited.  I'm wondering if the CPU resource could be better allocated and therefore the whole machine Host+Guests will be a little happier until the whole system can be upgraded.
IMO the server is under spec'd and should be replaced.

Host Details
ProLiant ML350p Gen8
CPU: Xeon CPU E5-2609  Appears as 4 cores  (HT not available on this CPU) (single CPU fitted, 2nd spare socket)
RAM: 64GB  (was 32GB until last week)
DISK: Several RAID-1  SAS 15K  
OS:  SERVER 2012 (R1) Desktop with Hyper-V role

Guest 1 Details
OS:  SERVER 2012 (R1) - Domain Controller

Guest 2 Details
OS:  SERVER 2012 (R1) - File Server, RDS Server (10 concurrent clients), SQL DB, LOB applications

Some screenshots attached.


Is the assigned 3vCPU and 1vCPU about the best compromise for the current hardware?

Is there anything within the Processor or NUMA configuration that could change to "improve" performance of the overall system ?

This physical CPU only has 4 cores.  This CPU was under spec'd from purchase.  Fitting a 2nd CPU now could help.

Thanks for any input

We're trying to resolve a new issue that cropped up when trying to configure DPM 2012 backups for our non-Microsoft VMs. The Linux servers are running RHEL 5.5 networked to the domain hosted on Hyper-V on Server 2012 R2. We had one Linux server which was able to backup when turned off. However, the remaining two servers (LINUXVM and LINUXVM2) failed to do the same. We've restarted the Hyper-V VMs a few times to no success. Migrating the VM to different Hyper-V machines also did not work. I copied the DPM and event logs from the backup and Hyper-V servers. Please assist, thank you!
I am running a Hyper-V VM on my windows server 2012 r2 server.  When I attempt to run the Event viewer or windows backup on the vm, I get an error saying "MMC could not create the snap-in;  The snap-in might not have been installed correctly.  Name: Windows Server Backup".  I of course googled it and have tried several "Fixes" but none have seemed to do the trick.

I have tried a registry key delete, replace a machine.cfg file, re-install gpedit.

  I need to move existing standalone SB2011 into 2016 Hyper-V server environment. For testing, I created two .vhdx file using Disk2vhd program from production SBS2011. Place them in in \HyperV\Virtual Hard Disks folder and created a new SBS2011 virtual machine using existing .vhdx files. The SBS2011 started successfully without a problem. Now the problems:

(1) I had to assign static IP information to virtual network card manually. I knew this in advance and no problem here.
(2) I also created a few more vhdx files from workstation PCs and created virtual Win10 machines . When I logged into a Windows 10 VM, it recognized mapped drives (F:  G: ... etc) to the SBS2011, but Outlook failed to start.  I remember a comment from EE expert about "need to shut down exchange services when creating VHDX file". But I did not do that this time.
(2) When I opened Services.msc in SBS2011 VM, some of Microsoft Exchange related services failed to start. These services were set to start automatically, but did not start. I started them manually, but Outlook still could not find exchange server.
(3) There were a few additional services that failed to start in virtual SBS2011 when I compare against production/standalone SBS2011.
(4) i read an article about runing "Fix my network" in SBS2011 VM.

I would like to hear from those  experts - who have personally migrated standalone SBS2011 into HyperV environment using VHDX file -

Hello guys,

I´m trying to setup monitoring for my new hyper-v server in Zabbix 3.0...I´ve already found a nice teplate for hyper-v but I miss replication monitoring...any ideas how to monitor hyper v replication?

Thanks for any help

I created a blank virtual machine in hyper-v But when I start the machine it is not getting started. It failed and giving error "virtual machine cant be started because a hyper v component is already running"

Please suggest the  solution i can use to solve this issue?

We have around 150 remote servers have been investigating some random server crashes for some time now without success. Each remote server has a windows 2008 R2 hyper-v running on it and the host server is running server 2012. Both the host OS and hyper-v seem to be crashing at random. We are running HP DL380's G8's of varying ages. Some of the server crashes are generating crash logs, others not. For those that have (to start somewhere) i have download all of the minidumps and put into Bluescreenview. The only ones that generate a dump file all have the same bug check code BUT seems to be very random drivers which leads me to believe for these servers its not a driver problem. Also on the hyper-v we see the same bug check code as the host often which leads me to think its a software package that's common between both Hyper-v and Host.

Questions i have:
1. If it was a software package would i not see the same driver crashing the system each time or could it still be a software package but the software is using multiple drives??
2. Is there anything else i'm missing on the dump files? I have attached these for anyone who wants to have a look. Would be greatly appreciated if anyone can help.

Hopefully someone can offer me some advice here. We have had about 70 server crashes reported in our endpoint management software in the last 14 days which keeps me up at night. Once i fix the host crashing we will investigate the Hyper-V crashes more.

My host was on a trial version and I upgraded to full license .  All my other VMs are starting correctly except my DC  it is showing the attached message . Any ideas what i can do ?  I even tried booting the VM from a ISO same issue , What gives ?Screen-Shot-2017-08-29-at-9.05.10-PM.png
I use Windows Backup program to backup a server. I can tell the backup files are in VHDX format. I found I am able to use Disk Management to "Attach VHD" that kind of VHDX file and it will show up as a virtual disk on the Disk Management. But I found I'm not able to open/explore it since Open / Explore selection are dimmed. Is it normal? I thought all VHDX files can be attached. Please help.
I would like to create a High availability clustering with 2 different servers.

I would like to create a Hiper-V virtualization (with 4-6 machines) to the first server and in the case of failure i would like the 2 machines to move to the other server.
How can i implement this?
we have a hyper V server that was acting weird and taking forever to boot (saying Applying User Settings).  When I removed it from the network it booted fine.  When I had removed the network adapter in it's VM settings and then added it back, the adapter under Device Manager says Microsoft Hyper-V Network Adapter #4 but has a yellow triangle with exclamation point with error code 31.  I've tried just about everything to get this thing back.  Any ideas?  Thank you.
Hi All...

I need to change the serial number for a virtual machine that is running in Hyper-V.  We built two machines from the same ISO and Hyper V assigned it the same serial number.  My vendor uses that serial number in its licensing so I cannot license the second machine as it says it already exists/is licensed.

I've found a lot of articles on changing the GUID but that isn't the Serial number.  I've also read through this article but it just shows you how to query it...not change it.  


Any direction or help anyone could provide would be greatly appreciated...

Background story:
Sat up a new Hyper-v server (2016)
Installed 2 vm's (win 2016). One DC and on RDS server.
Now servers are automaticlly booting every night at 21.00

Assumed it was Windows update, and since it can't be set to not boot during active hours (they work 22 hours a day), I used sconfig.cmd and sat windows update to manual - temporally .

But servers keep booting.

Found this in event viewer:
The computer has rebooted from a bugcheck.  The bugcheck was: 0x00000018 (0x0000000000000000, 0xffffc98bfc89bc80, 0x0000000000000006, 0xffffffffffffffff). A dump was saved in: C:\Windows\MEMORY.DMP. Report Id: 72adc51c-32be-48f6-9060-c2e9541f4dd1.

attached is newest file from c:/windows/minidump
memory.dmp was 800mb...

one more thing..
To save time I created one virtual harddrive and made 3 copies.
Want them as fixed size, and creating them during creation of vm makes them dynamic.

So, created 2 vm's using 2 of the copies.
3rd copy, was added to one of the vm's as a extra drive.

Now on both server I get errors "The disk signature of disk 3 is equal to the disk signature of disk 1."
Even on the vm with only one disk..

I have two 2012 r2 VM DCs running on a standalone Hyper-V 2016 host.  I set up remote management VIA PowerShell and Hyper-V Management console. I guess over WINRM with CredSSP.  Well everything was working fine (6-8 months or so now).  I all stopped a few weeks ago. I tried to pin it down to a security update but could not.  When I try to start a new PSSession or authenticate on the HVMMC I get an HTTP error code 403.  Everything I have found so far seems to be related to exchange and IIS,  neither of which are on these VM and the host is just Hyper-V it can't run anything else.  Also at the same time I could no longer check point my VM's which is required to work for my Unitrends recovery appliance.  It's like the entire management subsystem is broken.   I am still able to RDP into the host and manage the VMs with PowerShell but that's it...  I looked through application and error logs.  But I didn't see anything that appeared relevant to me...
I have been looking for a reliable solution to back up a Server 2012 R2 Server acting as a hyper-V host with 2 VMs. I see several expensive appliance based solution out there and others. I know data preservation is a top priority, but small offices have limited budgets that just don't allow for big solutions ($1500-2000 appliance then $300-400/mo for a 1 TB backup). I did read that windows server backup can do the job and I have used it successfully on servers. However, never on a Hyper-V host. Does anyone have experience in using it in this manner? I would like to hear your opinions?
Thanks - HBee
Dear all;
I have a problem. I had a server running win 2k8 R2 standard 64bit (6.1 build 7600), installed Hyper-V service
I restored a VM from Acronic backup successfully, but when i run the VM, i can not use the mouse
It said that "Mouse not captured in remote desktop session
searched many times on google. although i installed Integrations service but mouse can not be captured
i send 2 pic about this case; please help me to use mouse in VM
thks all2 pic...1 is notice on VM, 1 is setting on Integration service
Hello Experts,

I am hoping someone can tell what is going on here. I built a new Hyper-V host and migrated a couple of VMs to it from another host. When I went to modify members in the protection group I already had setup for hosts, it only shows Host Component when trying to add the VMs. The other hosts show their VMs. I even created a new protection group, and reinstalled the protection agent. It still does not show the VMs.

Anyone no what's going on?

I've got several VMs on a Hypervisor that are being backed up with Backup Exec. My understanding is that on the VM recovery checkpoints are created, the VHDX is copied to tape and then the checkpoint is deleted. My issue seems to be that, with two of my VMs, those recovery checkpoints are not deleting. If I right-click the checkpoints none of them give me the option to delete them so it needs to be done manually. If I neglect to do this I eventually reach the 50 checkpoint limit and the whole VM will fail to backup.

I'm working on getting a client off their SBS2011 Server and they have only one server. To make it a little more challenging I'm replacing all the drives with SAS drives to optimize performance so this will be a complete reinstall. This has to be done over a weekend so I'm trying to decide the best way to approach this so there is very little downtime. My plan is below and I'd like to know if anyone sees any gotchas.

Existing Server SBS2011 with Hyper V: SBS2011 is the DC for internaldomain.local

I plan on  building a new DC with a new domain name on Hyper-V and using our public domain name (newinternal.contoso.com) in Hyper-V on the current SBS 2011 Server, building out the users (only 15-20), connecting a few PCs to the new domain on the LAN to test. Export the VM to an external drive

Beginning afterhours/weekend copy all the data on the data drive to an external drive. Install the new SAS Drives, RAID 1 for OS, RAID 5 for DATA drives, Install Server 2012r2 with Hyper-V, then importing the New DC into Hyper-V, copy provision vhd data drive and copy all data off the external drive.
