2012 R2 guest hangs at hyper-v logo

Windows Server 2012 R2 Host with GUI.

Windows Server 2012 R2 Guest with GUI.

When the guest is turned on, it gets to the Hyper-V log with the spinning circle and goes no further.  The circle continues to spin.  After rebooting the guest three times, the recovery console comes up.  I can also enter the recovery console using the Windows Server 2012 R2 DVD/ISO. 

ChkDsk says the disk is fine.

SCF /SCANNOW/ /OFFDIR /OFFWINDIR did fix some files but that didn't help.

I have reason to believe the last round of MS updates hosed the guest.  Are there any boot logs I can check to see where boot is failing?

Hello,

I have a question about win server 2012 standard. I check on microsoft page and there is if I want to run many VM's than I must have datacenter. If I want to run up to 6 VM can I do it on standard or i have to buy datacenter. Is there someone who knows the line between Standard and Datacenter.

Thank you

Hyper-V MinimumBandwidthWeight

i have 2x 10Gig cards for iSCSI, 2x10 Gig cards for livemigration and 4x 1Gb cards for everything else.

I have set up 2x teams. one called livemigration on the 10 gig cards and one called converged on the 4x gig cards

I have set up a switch on each team

4x Gig cards as Cluster, Management, VMs and a couple of others. 

2x 10Gig cards as livemigration  only

iscsi not teamed - they're on their own separate vlans (isolated)

i set up the weights on the converged net as 20,20,20,20,20. Minimum flow of 50

on the livemigration i didnt set any weights

if i do "Get-VMNetworkAdapter -ManagementOS -Name * | ft Name, VMName, MinimumBandwidthWeight, BandwidthPercentage, IsManagementOS" i see the livemigration wieght lumped in with the others but its at zero. Does it aggregate the bandwidth as a whole across both of the switches?

Whats the correct way to configure weighting and flowcontrol? Also i see some people still using hypervport instead of dynamic - when should i used hypervport instead of dynamic???

Thanks

AVHD Keeps growing while VM is idle

I have an enviroment for automated testing where I configure 40 VMs (20 Windows 7, and 20 Windows Server 2008 R2) for testing. Each VM is cofigured to use a differentiating VHD out of an template VHD. After some basic configurations is made on the Differentiating VHD we snaphot de VM. This snapshot is the starting point for our tests.

We use the differentiating VHDs to save disk space ( we use around 1/3 of the normal amount we would use with dynamic VHDs). The snapshots are used to get to starting point for our automated tests. We want to Always start from the same point and we test our application several times a day.

Here is the issue:

I've noticed this week that after I revert the snapshots on the VMs, the System Process (PID 4) start having  lot of disk activity on the .AVHD files. In between 100-400 MB/s. It varies a lot. The AVHD. files on the Windows 7 VMs goes from around 500 MB after snapshot restore to 14 GB. This goes on for several munutes. After some time it stops.

The VM is idle and doing nothing. This disk activity is affecting a lot the install times of our application on the VMs. Normal install time is around 1 minute on SSDs, but due to this disk activity it's taking up to 16 minutes. Whe this thing stops, install times goes back to around 1 minute.

Physical server has 192 GB Memory, 2 SSDs in RAID 0 and dual 6c XEON E5-2632 v2 @ 3.5 GHz processors. It's running on Windows Server 2012 R2.

The issue beeing, why does PID 4 do so much activity and increase de AVHD file while the VM is doing nothing?

Hi Hyper V Guru,

I am trying to do inspect on the disk of my VM by right clicking the VM-> select settings -> Select Hard Drive -> and click on the Inspect. However I am encountering the error message: "An Error occurred attempting to connect to the virtual disk management service on computer 'localhost'. Cannot connect to the RPC service on computer 'localhost'. make sure your RPC service is running. what is actually the issue that happen?

Second query: how do I accurately confirm that my VM has no snapshot?

Third Query: if my disk is fixed vhd disk, is it possible to expand it? what are the best procedures and steps of doing this task? what I should notice properly before expanding? will there be any risk of expanding VHD? as this is our production exchange server and very critical, I am really worry of doing this.

Thanks for your attention.

Regards,

Henry

Hi Folks,

I am not a pro/tech but yes do have some very basic IT knowledge.

My situation is I ordered a dedicated server from OVH.ie and installed Windows Hyper-V Server 2012 R2. when i logged into server I encountered Command Line interface which i totally unfamiliar.

Now I want to create a Virtual Machine but know the process and the necessaries server commands to achieve that. Their is a guide that I have found on ovh.ie that shows how to connect with the hyper v server with help of vSphere Client. I am going to share the guild with you guys for reference: https://www.ovh.co.uk/g607.how_to_create_a_vm#system_change_mount_the_image_on_the_virtual_player

Please I urge your kind support as I have been struggling since 10 days! :(

Advice for setting up file sharing with VMs or physical server?

November 20, 2015, 8:20 am

Hi everyone. I currently have a 2008 R2 server full install running Hyper-V VMs (web and AD). The 2008 R2 operating system has folder and printer shares.

I am moving to a new hardware platform running 2012 R2 and would like to know how what best practice is in handling file and printer shares?

  1. Would I just install 2012 R2 (with a GUI), then create the file and printer shares for the users?
  2. Would I install 2012 R2 Hyper-V, then on it create VMs to hold all of the files and folder shares and printer shares? I suspect the VHDx files would group pretty large - I'm around 3TB for all of the office files already.
  3. Or is there another way I should approach this?

I am flexible in putting any # of disks on the network or attached to the physical server.

Thanks!

Hyper-V Replica Broker to multiple CSVs

With some help from the TechNet community and a whole lot of trial and error, I have successful configured my failover cluster and performed a couple of planned failovers. Hooray! However, I have 3 CSVs on my DR cluster and would like to utilize the entire disk space for replication. I have a replica broker on the primary side (not configured) and one on the DR side that points to the primary broker and points to 1 volume on the DR cluster for storage. I just found out that I cannot add additional volumes in the specified servers section by pointing to the same primary server. So do I  (A) make multiple brokers on the primary side with unique names and point them each to a CSV. (B) Delete my volumes and make one big one to facilitate all the replicas? Is there a third or even fourth option I haven't contemplated. Obviously, I would like to keep the setup as simple and efficient as possible. Thank you in advance for any help.

Hyper-V replication 2k8R2->2012R2 possible?

Are there any issues in moving a VHD on 2008 R2 running with a full GUI to a Hyper-V 2012 R2 server (no GUI)? Google comes up with nothing concrete.

Is it best to setup a one-way replication from the 2k8R2 to the 2012R2 box? Or should I just shut down the VM on 2k8R2 and copy the VHD file to the 2012 R2 server, convert it to VHDx on the 2012R2 server, , then bring it up on the 2012 R2 server?

I am experiencing an issue when I removed the Wireless device and then re-installed it on Hyper-V Windows 8.

The error states : "Failed while modifying virtual Ethernet Switch connection settings" followed by "Ethernet port {f...} bind failed unspecified error (0x80004005)"

Is anyone else experiencing this kind of issue?

Hyper-V+RemoteFX+RemoteApp

Heya.

I have a bare-metal Windows Server 2012 r2 machine with a Windows 8.1 Ent guest running in Hyper-V. Without the RemoteFX GPU added to the VM configuration, I can RemoteApp in with no problem. However, when I add the RemoteFX GPU I can RDP in normally (not RemoteApp), however when I try to run the RemoteApp RDP file (that worked fine without the GPU) it shows the "connecting" window for a split second, and then closes.

In the RdpCoreTS event logs there is an entry: "The disconnect reason is 0"

Let me know if there is any more information I can give.

An attempt to initialize VM saved state failed

Hi,

Just put clean install of windows server R2 on machine. Installed the Hyper-V role. When I go to create a new virtual machine using the default locations the process works fine. When I change the default location to a different folder  (i.e. on drive D: instead of drive c:) then although the virtual machine is created, when I START the VM to install the OS I get the message 'An attempt to initialize VM saved state failed'. It appears to be failing to create a saved state. I thought this might be a permissions problem but as far as I can see the permissions are identical on the default folder and the new folder on d:. I have tried recreating a different folder on D: but each time I get the same message.

I have read posts about incompatible snapshots and removing saved state before upgrading to R2 but I am not upgrading. I just want to create a new VM on a different drive.

Would be grateful if anyone has any ideas.

Thanks

VMMS causing all sorts of issues with backups and moving VMs

November 21, 2015, 9:17 am

I have several problems, and they all seem to be related to VMMS.

1) I cannot get a good backup with Backup Exec 2014 on two different machines unless VMMS is recycled. Even then, sometime the backup will fail. One backup is 10 hours and one is 3 hours. The 10 hours one usually fails on the Exchagne 2010 server - it is 1.2TB across 4 VHDXs.

2) I tried to move a VM from one host to another and it would fail. Had to restart VMMS on the destination server before the VM would move

Some things I have done:

1) Fresh install on Windows 2012 R2 on a server, updated, joined to domain, left in default 'Computers' OU.

2) Converted all VHDs to VHDX

3) Re-created all VMs - only reused the VHDX files

4) Converted VHD/VHDX from dynamic to fixed size

All servers are 2012 R2, domain connected, and Hyper-V is the only role. All guest services are up to date. There are no login restrictions.

Some of the errors:

Failed to fix-up absolute VHD paths in configuration of virtual machine 'VMNAME': Account restrictions are preventing this user from signing in. For example: blank passwords aren't allowed, sign-in times are limited, or a policy restriction has been enforced. (0x8007052F). (Virtual machine ID D547F8AF-109D-4A06-A312-3B25940BB921)

At the same time in the Application log:
A VSS writer has rejected an event with error 0x800423f3, The writer experienced a transient error.  If the backup process is retried, the error may not reoccur.
. Changes that the writer made to the writer components while handling the event will not be available to the requester. Check the event log for related events from the application hosting the VSS writer.

Operation:
   PrepareForSnapshot Event

Context:
   Execution Context: Writer
   Writer Class Id: {66841cd4-6ded-4f4b-8f17-fd23f8ddc3de}
   Writer Name: Microsoft Hyper-V VSS Writer
   Writer Instance ID: {d5e01751-b485-48eb-bc63-1c512e8db85c}
   Command Line: C:\Windows\system32\vmms.exe
   Process ID: 6624

Nothing of interest in the System log.


If I restart the VMMS service, it will work. This happened at 8:02pm and there are no account login restrictions.

Live Migration corrupts VHDX file - is it possible to repair?

August 8, 2014, 6:31 am

Hi.

I have a Hyper-V 2012 cluster with 5 nodes. All HP Blade servers in the same enclosure, on 3PAR FC SAN storage. I wanted to run routine maintenance on the hosts, i.e., Windows Update. So I Live Migrated the VMs off one host at a time, paused it in Failover Cluster Manager, rebooted, unpaused, and failed the roles back manually.

After updating the second host, I decided to fail the roles back when unpausing. The instant one of the VMs moved back to this host, it failed to start, and got a red X in FCM.

The VM had 2 virtual disks. I removed one, leaving only the system disk. When I started it, it ran CHKDSK a couple of times and eventually came back, appearing to be healthy (a miracle!). But I cannot add the second VHDX to the VM. It throws an error:

SERVERNAME': Attachment 'C:\ClusterStorage\Volume5\SERVERNAME\SERVERNAME-E.vhdx' failed to open because of error: 'The file or directory is corrupted and unreadable.' (7864368). (Virtual machine ID F4F4F4F4-F4F4-F4F4-F4F4-F4F4F4F4F4F4ID and name changed)

I've search everywhere for a solution, followed all the links. There are tools for VHD repair, but I can't find anything for VHDX.

I can't change to VHD format because the Edit Disk wizard throws this same error before it will even read it.

There is nothing wrong with our network or hardware, either. I had just done about 20 Live Migrations before this happened, and they all went just fine.

Anyone have any idea how I can recover this VHDX? Even if you know of a beta product, I'm willing to be a guinea pig!

Virtual SpinRite machine(s)

I am trying to set up a computer to handle multiple VM's, each running SpinRite on a single drive attached to the mother board.

I have that part all working, in the sense that SpinRite starts up and detects the physical disk I've passed through to it from Server 2008 R2. The issue is that SpinRite believes the VM is reporting the disks size incorrectly so it won't run. Do VM's do things to the reporting of passed through disks that could account for this?

VDI solution planning with Windows server 2012 R2

November 23, 2015, 4:07 am

Dear all,

We would like to setup a VDI solution but have a couple of questions, is there any can guide me to a correct way?

We are an educational institute and in our department there are 2 networks, one is public network 147.8.x.x, and the other is a private network 172.16.x.x, the private network serves our student laboratories computers. 

We have 2 AD servers running on 147.8.x.x network, and we have setup 3 additional servers running the RDWeb Access, Connection Broker and Virtualization Host services on the same network.  On the server with Virtualization Host services, we will configure additional NIC for a private network like 172.16.x.x, which we would like to serve the Hyper-V guests on the same server, which we emulate the situation like our student laboratories computers.

We have an existing UNIX-based VPN server, and DHCP server running to allocate IP addresses to computers.  We have searched some information on the Internet and found that some users may install a Windows-based DHCP server on AD to allocate IP addresses for its Hyper-V guests and install a RDS Gateway to either the RDWeb Access or Connection Broker server for Hyper-V Guest access between different networks.   But another solution is to install the DirectAccess RAS/Routing and Remote Access and enable the NAT routing.  May we know on our environment which solution should we choose?  We expect the student will connect through the existing VPN server and then connect our 172.16.x.x's Hyper-V guests, and to connect the Hyper-V guests from our existing student laboratories computers(172.16.x.x).

We would like to know which of the above solution or additional components would better be applied to our case.  Since we already have our own DHCP server running on UNIX side, we may consider to continue using it to allocate DHCP private IPs to Hyper-V guests, if possible.  For the part of Virtual switch, we still not familiar with it.  In case we need to setup a Windows-based DHCP server side the 172.16.x.x network, how can we control the DHCP broadcast to go to the Hyper-V guests only and how to avoid the Windows-based DHCP to allocate IP address to computers out of the Hyper-V guest?

Regards,

Patrick
