Hi guys,

I am using a 3-node WS 2012 R2 Hyper-V cluster. For all virtual machines I enabled resource metering. However, on a random basis Measure-VM stops displaying numbers, it just returns blank fields instead of values...resource metering is still enabled on a VM, but all values are empty. This happens to random VMs, while resource metering for all other VMs keeps working properly.

The only workaround is to disable & enable resource metering, however this resets values which is obviously a problem.

Has anyone had this problem?

I've posted this question a couple of months ago in another forum, but haven't resolved the issue yet. I'm hoping this post could help me troubleshoot this problem once again.

My question is as follows (copied from previous thread):

All my Windows 2012 R2 VMs (that run on a 3-node Windows 2008 R2 Fail-over cluster) are backed up by DPM 2012 R2 (also on Windows 2008 R2) using Saved State instead of Child Partition Snapshot. I've checked the list below (twice), but didn't find anything applicable to these VMs. 

• Backup (Volume Snapshot) Integration Service is disabled or not installed.
• The virtual machine has one or more dynamic disks.
• The virtual machine has one or more non-NTFS based volumes.
• The virtual machine Cluster Resource Group in a cluster setup is offline.
• The virtual machine is not in a running state.
• A ShadowStorage assignment of a volume inside the virtual machine is explicitly set to a different volume other than itself.
• An App-V drive is installed on the virtual machine that creates a non-NTFS volume.

I've set the registry setting SystemRestore\ScopeSnapshots to 0 for each VM, and checked the current state with the diskshadow tool (to make sure it wasn't just an erronous datasource text in DPM). 

Some more information:

• all Windows 2008 R2 servers on this cluster are backed up by DPM using Child Partition Snapshot
• all VMs (VHDs) are located on an HP Lefthand SAN

I'll appreciate any pointers in finding the root cause of this problem!

Just wondering if anyones experienced this?

I have a customer with a 4 Node 2012R2 Hyper-V Cluster.

Sometimes performing a checkpoint will cause a VM to reboot. It's happened to both VM's running windows 2008R2 and 2012R2 with latest versions of integration tools installed.

Anyone ever seen this behaviour?

Thanks

Hey all!

So, I installed Hyper-V 2012 Core on a box, patched it, and then joined it to the domain. If I connect to the server via Hyper-V Manager from either a Windows 8 machine or Server 2012 machine and try to create a VM, it says "There was an unexpected error in configuring the hard disk on [Insert VM Name Here]." I feel like I've tried everything. I can not create the disk manually via the Manager on its own, before or after the VM being created. I can, however, create the disk via PowerShell with out a problem! Via PowerShell, I can create a dynamic VHDX disk every time without an issue.

I was curious if anyone has had this problem and/or knows a solution.

Thanks in advance!

Good morning:

I am seeing a "General access denied" error when attempting to replicate a VM from an on-site 2012 cluster to an off-site 2012 cluster.  Both clusters are Hyper-V 2012, each with their own Replica Broker configured.  Each broker configuration uses Kerberos, constrained delegation (configured to allow each locations hosts to be source and destination on the other), and a unique CSV storage path at each site.  When I right-click a VM and enable replication (from our primary site/cluster), I type the hostname of the replica broker for the destination site, ensure Kerberos port 80, compression enabled, select the VHDXs to replicate, use only the latest recovery point, begin immediately, send over network, and receive the following message:

Enabling replication failed.  Hyper-V failed to enable replication.  Hyper-V failed to enable replication for virtual machine 'virtual machine': General access denied error (0X80070005). (Virtual Machine ID unique ID).

What is very weird is that replication works in the opposite direction.  That is, from our secondary site to our primary site.  I can see the replication progress in Hyper-V Manager on that VM's host.

Hello. I have just enabled Hyper-V on my Windows 8.1 laptop.
Dell Latitude E7440 i7-4600U @ 2.10GHz
I can create a Virtual-Switch but I am unable to create a new Hard Disk or Virtual Machine within Hyper-V. I get the same error for both processes.

Error: The Virtual Machine Management Service encountered an error while configuring the hard disk on virtual machine New Virtual Machine.
Failed to create the virtual hard disk.
The system failed to create C:\Users\user\Documents\Test\New.vhdx .
Failed to create the virtual hard disk
The system failed to create C:\Users\user\Documents\Test\New.vhdx . A Virtual disk support provider for the specified file was not found. (0xC03A0014).
I have ran all Dell Client System updates and all of windows updates.
I have attempted to create a virtual machine on the current SSD and also an external drive. The same error appears.
I have also attempted to create a virtual hard disk via Hyper-v with a Base vhdx, still the same error occurs. I've tested the base image on other laptops of the same model and windows 8.1 without issue.
Any thoughts on how I can fix this?

Thank you,

How to change the default gateway of 2 hyper-v hosts which are part of a failover cluster

Hi guys,

We recently changed our firewall and I have to change the default gateway, and the secondary DNS entry for all the machines that have static addresses on the network.

When I reached the hyper-v nodes (running Windows 2012 which are part of a failover cluster) I asked myself should I do it individually for each host, or on the cluster. It seems like a simple thing to do but I didn't find a way to do these changes so that I do not cause a problem to the cluster and the VMs

Any advise from you hyper-v gurus ? I'm fairly new to the hyper-v world (comming from vmware).

Thanks

Hi
I have a HP DL380G8 Server (32 cpu+ 192GB of RAM)
Windows server 2012 R2 on base and installed 7 Hyper-V machines with windows server 2012 R2 too.
I set all my business on this solution on 7 different Hyper-v servers.
One is AD-DC and DNS and each other server has own tasks.

My problem is after running this solution I have network issues. after about 2 days, some of my other network devices such as Access points stop working!!! or become tooo slow and when I shut down 3-4 of Hyper-V machines (or unplug network cables of server) they start working again (Until plugging cable in).

- I added Hardware of any Hyper-v (4 CPU and 8GB of RAM each one)
- I changed network adapters to Legacy NA 
and still problem remains.
Please Help me. I did a huge risk on my job safety by using Hyper-v.

Regards
Mohsen

Hello, here is my hardware for my Hyper-V host that will be running 4 VM's for 20 users and may max out at 30 - 35 users in the future:

PowerEdge R520
2 -Intel Xeon E5-2420 v2 2.20GHz (24 Total Cores)
64GB RDIMM, 1600MT/s, Low Volt, Dual Rank, x4 Data Width
300GB Raid 1 for the Hyper-V Host (2 -300GB 15k SAS Drives)
1.6TB Raid 5 for the VMs (4 - 600GB 15k SAS Drives)
4 - 1GB NICs (1 NIC for the Host and 3 Teamed NICs for the VMs)

The VM's I will be running (All will be running Windows 2012 R2 Standard GUI):

1 - Domain Controller (Active Directory, DNS, DHCP and File Sharing)
2 - Backup Domain Controller (Active Directory, DNS)
3 - Microsoft SQL 2012 Standard possably 2014 and Microsoft Dynamics GP
4 - Remote Desktop Server - 5 to 10 users (Running Office 2013, Microsoft Dynamics GP Client)

I know this is not an exact science but was looking for a safe configuration to start out with and will tweak once it is in production.  This was just a guess on how I was going to start out:

1 - Domain Controller
CPU 6 Cores
12GB Memory not Dynamic
60GB VHDX Fixed Size, I will also create VHDX Fixed Disk for my Data

2 - Backup Domain Controller
CPU 2 Cores
4GB Memory not Dynamic
60GB VHDX Fixed Size

3 - Microsoft SQL
CPU 8 Cores
32GB Memory not Dynamic
60GB VHDX Fixed Size, I will also create VHDX Fixed Disk for my SQL Data

4 - Remote Desktop Server
CPU 6 Cores
8GB Memory not Dynamic
120GB VHDX Fixed Size

Here's the scenario.

I have 4 Poweredge R710 Servers each with a total of 12 1Gb NICs connected to 2 phyical switches for redundancy. I have 4 of these reserved for ISCSI storage connectivity.

For the remaining 8 NICs previously in a Server 2008 R2 cluster I would have had the following:

Management Team (2 NICS)
Backup Team (2 NICS)
Hyper-V Team (2 NICS)
Live Migration (1 NIC)
Cluster/CSV (1 NIC)

Now I want to upgrade the Hyper-V cluster to Server 2012 R2 using the same hardware and I have read much on converged networks, smb multichannel and new inbuilt NIC teaming.

I understand there are many different ways to design the networking now and therefore for the networking hardware I have available what are other peoples thoughts on the best design.

Should I keep the old style non-converged networking and have underutilized NICS for much of the time or would a converged network design be able to provide better network performance?

Say for example I create a TEAM of 8 x 1gb NICs and split the Management, Backup, Hyper-V, Live-Mig and Cluster/CSV with vNICS and weighted QOS I would see improvements in the networking?

What are your thoughts?

I'm hoping you may be able to help.

Whilst trying to start a new VM on my lab system, I am getting the "Could not initialize memory, not enough disk space" message when I try and use a new drive to store the hard drive for the OS.

This new drive is a logical partition. It seems to function fine within the usual windows tools, can be browsed, appears in disk manager, etc.

I've assigned Full permissions to "NT VIRTUAL MACHINE\Virtual Machines" and "BUILTIN\Hyper-V Administrators"

The machine creates fine, as do the VHDX files and their permissions seem to match existing machines.

I repeated the same process on a pre-existing logical drive and the machine starts fine.

I've checked memory on the server and it's only 10% used, so it doesn't seem to be the RDP memory problem and the .bin file is created when I start the machine up.

I'm thinking there's something I missed when I created the disk. To do this, I used diskpart in HyperV Server Core command prompt having selected the required disk...

1) create partition logical size=X

2) assign letter = K

3) format fs=ntfs quick

then...

icacls k: /grant "nt virtual.....":(OI)(CI)F

Am I missing something obvious? It does seem specific to the disk.

Hello,

I have a Hyper-V environment consisting of Windows Server 2012 (not R2) hosts at a primary site and at a disaster recovery (DR) site. Failover clustering is in place with Hyper-V replication taking place between the two sites. Each site belongs to a different subnet with a different VLAN scheme so to perform a planned failover successfully IP failover must occur. 

Everything works properly. The problem I have with this is that it is extremely cumbersome to have to manually enter the IP settings for both the primary and replica VMs. I wanted to ask if there was a better way to do this. Other than PowerShell, how would this be done if a hundred or more machines needed to be setup this way?

Thanks

Hi All,

  We have Hyper-v cluster with 6 nodes. Currently I’m facing some issues with hyper-V cluster CSV backup with EMC networker. Current configuration as below.

All the servers are hosted in different data center . we are using vendor backup solution and it’s in different Network segment . we have DEDICATED NETWORK CARD FOR EACH HOST and added the static route for all the hyper-V servers. And hyper-v host can ping to Media server. But when the media server try to backup it’s not starting.

OS =  Windows 2008 R2 Datacenter SP 1

Network configuration :

Separate network card for all the Interfaces.

Management Network : 10.1.100.XXX range all the six servers

Cluster IP  : 10.1.100.XXX

Live migration network : 10.1.3.XXX range all the six servers

HB  network : 10.1.3.XXX range all the six servers

DMZ Network :

VM Network  :

Backup network : 10.1.113.XXX range all the six servers

EMC networker application cannot communicate to hyper-cluster cluster. any idea why? Is it possible to add new backup vlan IP address to Cluster Name?

Thanks,

we have DPM 2012 SP1 backup to VMs on a 3-node Windows Server 2012 R2 SP1 Hyper-V cluster directly to tape for so many months without issues.

However, this month we had a very sad scenario.

The backup starts at 12:00 AM, at around 3:30 AM VMs on two nodes out of 3 failed due to being unable to access storage.

We get events about virtual machine configuration not available for all VMs hosted on these two nodes. After less than two minutes we get events that the VM configuration is again accessible.

during the two minutes of failure, 5 VMs were reported in event viewer as degraded on both nodes. these 5 VMs stayed down after the configuration became accessible.

other VMs on both nodes restarted unexpectedly, however, one 2003 server VM showed Boot failure and another XP VM showed Blue Screen 0xF4

When we arrived on site at 5:00 AM, we started the 5 degraded VMs without issues, and resetting the 2003 and XP VMs worked also.

However, we found the CSV in redirected access for backup, and backup was still running. needless to say the VMs were very slow.

stopping the backup restored the CSV to the online state.

any insights about the cause of this trouble!

PS. we are planning to restart all the nodes and DPM server and try the backup again to see how it goes.

I am running Server 2008 R2 with Hyper-V. All virtual machines are stored on an iSCSI SAN. I have three host servers in a failover cluster.

Yesterday, one of my host machines failed and shut down unexpectedly. Failover occured as expected but the machines which were on that host were shut down uncleanly. One of them was a VM running Server 2012 which runs SCCM 2012.

I got the failed host machine back online and spread my VMs out over the 3 servers again. At this point I had not started my 2012 VM back up.

I tried to boot my server 2012 VM today and it has been stuck on a dark blue server 2012 screen with Please Wait and a spinning circle for 45 minutes at the time of writing this post.

I don't know what's happened to this machine - or why it is stuck. It was shut down cleanly yesterday when the failure occurred. Is there anything I can do to get this VM up and running again?

Edit:

It finally finished booting so I could log on. It took an hour and 6 minutes to get to the login screen. If anyone has any ideas why this might have taken so long (all other VMs are fine and boot quickly) and how to prevent it from happening in the future, I'm all ears!

It's now taking a while to actually login, mind you... stuck on applying user settings... so presumably there's still a problem somewhere.

Hi I am trying to find the best way to migrate from ESXi to Hyper-V with Server 2003 DC with two hard drives. I know I should not snapshot the DC so I guess what's the best way to do this. Here is the one catch I only have on physical host. 

Should I uninstall the VMware tools, shutdown all my servers, export the vm to an OVF, uninstall ESXI, install HyperV, convert the OVF to use with HyperV, import the machine and than boot up?
