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.

For PCI compliance and self-certification, we'd like to know if our Windows Server 2012 (not R2) Hyper-V hosts would include any memory data from hosted VMs in a memory dump file?

While we store zero cardholder data to disk, it's certainly held in volatile physical memory on the host while our storefront VMs are running.  So, in the event the host crashes and writes a dump file, would it contain any memory data from the VMs that were running at the time of the crash?

Thanks.

We have a group of 2012r2 hyper-v servers, some of them in a failover cluster, some of them standalone.

I have a couple developers I want to give permission to open the hyper-v manager to restart their servers.  I have given them permissions through GPO that allows them to RDP and open hyper-v manager to manage the non-clustered hyper-v servers, but the same permissions won't work on the clustered hyper-v servers, they get an error saying they don't have permission to connect to the servers.

I have a security group called 'dev_admin', and on the OU for the hyper-v servers I have a GPO that is giving dev_admin rights for Log in Locally, log in through terminal services, and under restricted groups have put dev_admin into the remote desktop users, and Hyper-v administrators, and to test I even put them into the builtin\administrator group for local admin rights (I don't want to use this except to test, but still no joy)

BTW the iscsi SAN machine is also in the same OU, so all the servers are getting the same GPO settings.

What am I missing?

I have a Hyper - V host that hosts 3 VM Servers.  Two of the servers have multiple checkpoints and a "Now" Checkpoint.  Everything is running well, but disk space is starting to concern me.  I would like to merge the current configuration (Now) into the .VHDX file and remove all of the .AVHDX files.  My understanding is that deleting the checkpoints will do this automatically, and that this can be done without shutting down the VM, but I am not sure in what order that should be done.  Oldest to newest?  Newest to oldest? or by some other method.

I have not been able to find documentation on how to accomplish this.

I'm trying to install the evaluation version of MS System Center 2012 Virtual Machine Manager and get the following error at the end of the installation (see screen shot).

I did download install winrm 5.1 separately after looking at KB2742275 however that didn't help.  One requirement  MS has is being joined to a domain.  Is there any way to install this without a domain controller present?

Thanks

Im looking to convert one of my physical servers (server 2003 SPK2) to a VM to host on my hyper-V server (Server 2012 R2)

Is there a server backup software that can image the entire disk (1 physical disk 2 partitions) then restore the image to the Hyper-v server?

I am running hyper-v on server 2012 R2.  Calling myself clever, I thought I would bridge two NICs on my host and then attach me Hyper-V switch to that.

Well, hyper-v doesn't see the network bridge.  It only sees the NICs in the host.

Does Hyper-V support connecting to a bridged NIC?

Thanks

I found these alternatives:

http://lifehacker.com/5714966/five-best-virtual-machine-applications

Which of them should I use if I am willing to pay and speed and performance is important? Isn't the already integrated Hyper-V a virtual machine application also, so I don't really need any external virtual machine application?

Hello,

I am trying to simulate a replacement of VMware ESX on Hyper V running on server 2016.
In my lab, I have two physical servers with the hyper V role installed, the failover cluster manager role and the Hyper V replica broker role. Storage is presented via iSCSI target on Qnap NAS.

Here are my questions.
How do I configure the DRS function? What allows that function?
I attempted to configure Replication, and I received an error that I could not replicate virtual machine to the same cluster.
Suggestions Please

Hello,

I have a Windows Server 2016 Standard running Hyper-V Role with four VM’s installed.

I have read a lot about not putting Antivirus on the host machine for all sorts of reasons and it’s isolated and rarely gets logged into and only by me. I don’t do any browsing or downloading on it. After the horror stories, I’ve decided to leave it Antivirus free.

The Guests are a different matter, I have four licenses of ESET File Security and just want to confirm I should install this Antivirus within the guest OS’s

The VM’s are backed up regularly on and off site by Altaro VM Backup software.

Your thoughts are welcomed…

Thanks

Dave

Hi,

i have a server HP DL580 G7 running on RAID 50 with 8 1TB drives.

the server had Server 2016 DC installed and the HyperV role.

now everytime i want to copy a HyperV client on this server the server crashes with the blue screen " DPC Watchdog Violation "

what can this causing and how to solve?

Hi Team,

We have 2 domain controller running on high end physical servers,i think we are wasting the resource by just running domain controller on these servers ,so we planned upgrade the memory of both those servers and run Hyper V on both this server so that we can create virtualize most of our physical server,i want to create cluster of both this server.

My question is can i leave the domain controller on this servers as it is and just install the Hyper V service and start using it ,is this recommended,if not what is the best recommendation?

I have a hyper-v machine the folder is large and I want to make it smaller.
The is have a partition of 126GB which is more then half empty. and it have a partition that is uneducated. I thought if I to remove this uneducated partition the folder size will get smaller.
Please advice

I would like to make a few 100 vm's available for remote users to access through a Barracuda 480 SSLVPN Appliance. These users will be logging into these vm's on a daily basis. I'm a little unsure about which direction to go. Do I do a virtual machine based or session based deployment? All of the documentation that I have read is very confusing at times. I have a Nvidia K2 installed on my host so I will be applying remotefx on those vm's.

is there advantage of having more than 1 NIC on a Hyper-V host?

I ask because I'm ordering a new server.  The server will have 4-5 VM's

Hi All,

I have a 2 node hyper v cluster running a bunch of virtual machines.

I can successfully connect to the cluster via failover cluster manager with no issues. I have run the validate cluster tool which passes successfully also

When I right click on a node and select 'connect' I get the console window as expected, however it only works on hyper v host 1 not hyper v host 2.

When I also try and connect to the problem host via Hyper-V manager I receive the following:

Any suggestions?

The idea is to move from vmware to hyper-v

i installed a host server with the new server 2016 Datacenter and installed the role hyper-v on it.

questions i have:

1. do i need to create a seperate DC controller to connect al my hyper-v hosts to?
2. in vmware we have vcenter to control all the hosts from one place. does hyper-v have this to?

We have an Okidata ML420 connected to the network via an HP 170 Jet Direct.  It will work for months and then only print part of the print job.   I have to uninstall it and reinstall it.  
The network is Win 2008 R2.  The printer is installed on a Hyper-V VM.  I wasn't using a Print server, previously, but today I set one up.   I'm not physically at the office so I don't know if this will help.

This is a big problem because we do all of our invoicing from this printer.  

Any suggestions will be appreciated.  I'll be at the office Monday.

Consider the following scenario:

Customer wants to deploy a new lab hypervisor running a Intel Kabylake family CPU.  They want to install Server 2016 on it, which supports Kabylake.  However, the guests they want to run on this hypervisor are 2008 R2 and Server 2012 R2, and Kabylake doesn't support those.  Will the guests be unable to obtain Windows updates, as documented in this article?

"The processor is not supported together with the Windows version that you are currently using" error when you scan or download Windows updates

I connected to a random Server 2008 R2 VM on the current lab hypervisor, and ran msinfo32 on that guest.  Sure enough, I can see that an Intel Xeon E5645 CPU has been detected as the system's processor.  So it seems guests are aware of what specific hardware they're running on, and I won't be able to get updates?

Basically, Whenever I run Measure-VM against one of my 2012 R2 servers, I only get data back related to disk usage. CPU, RAM, and Network are all blank. Both the host and the guest are 2012 R2 servers. I attached a picture of the output.

Dear All

Please, can someone assist me? I am trying to wrap my head around how many VM machine I could run on the below CPU, I don't know how you calculate this and it's starting to annoy me somewhat that I don't understand.

Intel Xeon E5-2620v3 (2.40GHz 15MB Cache, 6 Core)

I'm new to this and trying to understand how it all works together. On my machine I have 2 partitions, C & E. On the C drive I installed Windows Server 2012 R2 (named DC2) which will eventually be setup as my primary domain controller. On the E drive I installed Hyper-V 2012 R2 Core (named HV1). As the machine boots it ask which server to start and I select Windows Server. On the Windows Server I added the Hyper-V Manager feature.

When I try to connect to the Hyper-V Server it says , cannot connect to the RPC server on computer 'HV1'. Make sure the service is running. It makes sense to me because I started Windows and not the Hyper-V. How do start both servers or am I not understanding how these these servers work together?

Dear Experts,

Need urgent expert suggestion. Our hyper v cluster formed on SMB as storage is going unstable lately for some reason. Vm's just goes missing out of no where, the cluster behaves erratic, Host communication goes down from VMM but actual host will be running

We had this situation twice earlier and somehow recovered but this is recurring again like once in 10 to 15 days.

Please suggest where else to start looking for reason and if there is any trouble shooting guide to iron out the problem

Thanks and looking forward

Best Regards

Dear EE

I got 2 servers running Hyper-V Server 2012 R2. We'll call them Host1 and 2.

Host 1 has 2 VMs that are replicated to Host2 using Hyper-V replication.

I need to do maintenance on Host1 urgently.

So here are my questions:

1. How can I move the VMs to Host2 with no downtime?
2. Seeing as replication is enabled do I first need to remove replication before moving the VMs to Host2?
