Hi,

Since we installed the new version of Data Protection Manager 2012 R2, we get issue messages while backing up Windows Server 2008 R2 or 2012 R2 virtual machines. 

At every backups we will find the followings in Event Viewer:

Hello,

i am having a working environment for storage-migration Hyperv-2012R2-machines to a windows SMB-server.

Now i am also try to do a storage-migration to QNAP-NAS.

This NAS is joined to the windows-domain. I have created a Domain-Security-Group with my 2 HYPER-v-hosts in it. This Group is has Full Control to the Hyper-v folder where the storage-migration goes to.

I receive the following error when doing a storge migration to the QNAP:

What is the difference here with SMB-file share on the windows-machine and is there an option to fix this issue?

Thx

I'm trying to enable Hyper-V Replication from a 2012 Hyper-V core to a 2012 R2 Hyper-V core. This is going across different domains through a WAN connection. I created and successfully enabled certificates on both servers.

Disabled windows firewall on both servers with "Set-NetFirewallProfile -Profile Domain,Private,Public -Enabled False". Replica server is configured with a static public IP. I can establish a connection on 443 from primary server to replica server and view the connection with netstat.

However, I get the "Could not get configuration details of the specified server" from the replication wizard. If I continue through the wizard I eventually end up withEnabling replication failed. Connection with the server was terminated abnormally (0x00002EFE). It fails to establish a connect with the replication server.

The odd thing is that if I run netstat on the primary server during the replication wizard I see no traffic leaving the primary server. Nor do I see traffic leaving the Hyper-V manager computer, which happens to be a vm on the primary server. I do however see traffic between manager computer and primary server during the replication wizard process.

It looks like the primary server never attempts to reach the replication server.

I checked the security logs of primary server and see 4634 Logoff,5058 Other System Events, and 5061 System Integrity entries. There are also 4776, 4624, and 4672 entries. Administrative Events display29310 and 32000 errors from Hyper-V-VMMS.

I'm stuck. I'm tempted to take the replica server and connect it to the same LAN as the primary server and live migrate (shared nothing) the VMs so that I can have both hosts on 2012 R2. But this may not be a solution.

Can anyone clue me in to what I'm missing??

I have a possible idea for you that I know I would find helpful. I understand that certain VM settings can't be changed while the VM is running. I would love to be able to make the change so that next time the VM restarts, it can first have those settings changed for me before starting up again. That way, I could make the change (although it would tell me it couldn't be changed right now), and schedule the computer to restart sometime overnight, so that I don't have to either a) get up at 3am to do it manually or b)work out what powershell command to run which would shut the machine down, make the changes, then start it up again - and hope that I'd done it correctly :-)

I hope this is a useful feature request. Generally very happy with all the improvements you keep making, thanks.

(I didn't find anywhere else I could submit a feature request, so I hope this gets to someone that can use it.)

Hello Hyper-V guys!

I want do deploy a simple Application Server (2 CPUs), where there are some tasks who need to be seperated from OS to OS (So not running on one Host).

I know with a Windows 2012 R2 Windows Server i can set up two Hyper-V VMs.

But i have also a Application that runs on Windows XP (and can't be upgraded) and a Solution in Linux.

If i want to Set up 4 VMs = 2x Windows 2012 R2, 1 XP and 1 Linux on Hyper-V how much Windows-Server 2012 R2 Licenses do i need?

Thank you very much for your help.

Hello

Scenario: I installed Hyper-V Role on Windows Server 2012 R2 x64 Standard(Workgroup) with 2 Ethernet  one for private network with rang 192.168.100.10and another for Public (or better say Internet) 192.168.1.10ComputerName=BASE.

.first virtual machine created and installed as Primary Domain Control (windows server 2012 r2 standard x64) with one vEthernet (192.168.100.2) second Virtual machine created and installed as Certificate Authority (windows server 2012 r2 standard x64) with one vEthernet (192.168.100.3) and third virtual machine created and installed as Kerio Control (firewall) with 2 virtual network (first vEthernet 192.168.100.1 as private and second card 192.168.1.6 as public and internet).all 3 VM joined Domain.all clients (joined Domain)for access to internet goes through Kerio Control.

I have one Static IP (public IP) from ISP for access to server from internet. know for accessing to server computer I had to configure port forwarding for example 192.168.1.10 with port 80.

Question: with this scenario I want to connect to PDC computer with ip 192.168.100.2 by internet.

1.BASE - 192.168.100.10 / 192.168.1.10 (Workgroup)

2.PDC - 192.168.100.2 (Domain) -VM

3.CA - 192.168.100.3 (Domain) -VM

4.Kerio - 192.168.100.1 (Domain) / 192.168.1.6 (internet) -VM

PDC and CA for access to internet use 192.168.100.1 as Default gateway.

I really Appreciate if Someone help me.

What would be the best and most efficient way to complete the following:

I have a Windows 2008 R2 Hyper-v Hosting server, with a Windows Storage Server 2008 ISCSI connected storage drive. I need to move all the Hyper-V images from one ISCSI drive, to another ISCSI drive, as I just purchased another Windows Storage Server 2008 that I setup a ISCSI drive on that I want to store the Hyper-v images on.

Is the best method a export of each virtual server, then delete the current server, and them import them back from the new location?

Having a bit of a problem with a hyper-V environment which does not seem to route network traffic on two different subnets between each other.

If it were a purely physical server with two NICs and a gateway set traffic would automatically be forwarded between the two different subnets.

However when one of those NICs is a hyper-V virtual switch this simple routing no-longer seems to work and no traffic gets forwarded between subnets?

Situation is:

Hyper-V server with two NICs

• NIC 1 = 192.168.0/24 - main Internal company network.
• NIC 2 (hyper-V virtual switch.) = 192.168.1/24 - connects to ADSL internet router

Virtualized Domain Controller.

• One or two virtualiszed NICs as necessary
  

How then does traffic get routed between these two subnets?  If RRAS has to be configured to do this where is the best place to do it, on the hyper-V host or on the virtualized domain controller?

Thanks,

Hi,

Recently I spotted a strange problem - my task manager displayed memory usage up to more than 90% with no particular reason, as all processes in total were consuming up to just 20-30% of RAM.

After some investigation I noticed that after starting/restarting a guest machine memory usage drops back to normal.

You can see that memory usage drops at the moment I started a VM that wasn't previously running. At some point memory consumption starts to increase and again drops when I perform some start/stop actions with any WM. I got 2 VMs, one is Windows XP Pro and another is Ubuntu Server 12.04, both set up for static 512MB of RAM.

The machine is Windows Server 2008 R2 Std

Did anyone experience something like that? I really don't know what is the reason of such strange behavior.

Cheerz.

Hi,

Im trying to enable VMResourceMetering for all VM's on a Windows Server 2012 R2 hyper-v host.

Using command:

get-vm | enable-VMResourceMetering

Some of the VM's report a failure when I'm running the command while some VM's will be successfully enabled with VMResourceMetering.

Does anyone have an idea why some fail? Is there any requirements for enabling resourcemetering?

Hi!

We have teamed all the 4 NICs on our Win 2008 R2 Hyper-V Servers running on HP Servers and included all the NICs in the Team using HP Teaming Software. The single virtual switch has been assigned to the VMs. Our network switch where the servers are connected is 1 Gbps but the teamed NIC is showing 4Gbps and the virtual switch is showing 10Gbps. Will we get any benefit for teaming?

Thanks.

Issue configuring vlan-id on virtual machines

Hi all,

I seem to be having an unusual problem getting a switch trunk port to recognize the Hyper-V vlan-id tags. 

Here is the problem:

Environment:

• Virtual Machine: Windows Server 2012r2 eval (vhd) configured as a domain controller
• Physical Switch: Cisco Catalyst 3550
• Host/Physical Server: Windows Server 2012 (not R2) Standard
     (no big name parts: motherboard and nic's put together from various sources)

I am following the instructions listed in the Hyper-V: Configure VLANs and VLAN Tagging forum article that I see many linking to...BTW, I am not using NIC teaming.

This all seems simple enough--and it seems that many others are getting this to work...but not for me  :-(

Here is the problem: 

This works:

• Configure the physical switch port as an access port for the specific VLAN (129)
• Configure an 'external' virtual switch (no vlan-id) and attach to the above access port
• Do not configure a vlan-id for the VM

This does not work:

• Configure the physical switch port as a trunk port (with all VLANs allowed)
• Configure an 'external' virtual switch (no vlan-id) and attach to the above trunk port
• Configure vlan-id 129 on the VM

When I do this configuration I am no longer able to access the 129 VLAN.  On the physical switch, I can see that the packets are delivered, however they are untagged (they show as belonging to the native vlan-id 1).  However, I do see that the physical switch recognizes the virtual switch as a peer and trunking is enabled between them.   If I run 'Get-VMNetworkAdapterVlan' in powershell on the host machine, I see that the network adapter for the VM is in Access mode and the Vlanlist (vlan-id?) is 129.

So, it looks like Hyper-V thinks it is tagging the traffic, but the Cisco switch does not see the tags.  This would seem to point to the physical NIC I am using on the host server.  However, I can find no other example in the forums of a NIC not supporting Trunk mode.  Also, the switch recognizes the virtual switch and sets up a trunk session with it.

I feel like I am missing something very obvious here.  Can anyone offer any suggestions?  My goal is to be able to setup multiple VLANs to isolate/route traffic between VMs and the rest of the external network.  This is a test/learning environment so experimentation is welcome ;-)

Thanks,

Alex.

I can't start my VM after i deleted my snapshot.
Before I deleted my snapshot it said merge in process but becouse I ran out of disk space I had to delete the snapshot.
The error I get is
"An error occourred while attempting to change the state of virtual machine.

It still says Merge in Progress and when I click on Cancel merge in progress I get the following error.
"An errror occurred while attempting to cancel the

Our Hyper-V server and VM's were in-place upgraded some time ago from Windows Server 2008 SP2 to Windows Server 2012. We would like to use Dynamic Memory but when I try enabling the feature it is not working at all. I set the VM to start with 512MB and have a minimum of 512MB and a maximum of 4096MB. The VM starts and just comes to a crawl once the OS boots. No value ever appears in the memory demand. The Integration Services are fully updated.

Is there something that did not get set correctly due to the in-place upgrade?

I have this feature working fine on my home network using the free Hyper-V server with these exact settings. Why would this not be working?

I have two laptops each running Windows 8.1

I want to transfer a VM running Server 2012 R2 from one to the other.

Within Hyper-V Manager I shutdown the VM and export it.

Copy the files to the new laptop

Within Hyper-V manager I choose to Import

I can fire up the VM and log in with the Administrator username and password, but there are no installed apps available - eg Visual Studio. Also if I search for Control Panel it doesnt find that either.

Am I missing anything in my process?

An additional piece of information is I dont have network access either from the new VM. I created a new virtual network switch in the Virtual Switch Manager.

Hello,
I'm testing Hyper-V and three virtual machines (512MB of allocated memory) on 2GB of physical memory.
It has run during some hours but suddently, all VM switched to "paused-critical" state. What's the reason? Is it a problem of memory? I know I'm pushing the computer limits but when I turned off one of the VM, I was able to start the others. The machines have run during few seconds and switched again to the "paused-critical" status.
