Hyper-V "Failed to import a virtual machine"

≫ Next: Hyper-V - Can not install Integration Services

≪ Previous: Create a new port/ New Virtual network adapter

This feels very much like a repeat of other questions, but I've been through the forums and can't find an answer.

We have two Hyper-V servers: one is Windows Server 2008 R2 with Hyper-v installed (not core, the full server installation) the second is Hyper-V server 2008-R2.

I created a Virtual machine on server 1 (call it VMH1) to upgrade our Dynamics SL installation, so it has SQL Server on it as well. Using the Hyper-V Manager, I shut down the VM and exported the VM. That took about 20 minutes and finished with no errors. I then copied the export files to VMH2, the Hyper-V Server (which took about an hour) and ran the import there. Got the "Import file format error" which seems to have happened frequently with the 2008 RTM version, but everyone agrees was fixed with 2008 R2. The .exp files don't have server names in them.

So, I created a brand-new VM running Windows Server 2008 on VMH1, joined it to the domain, etc, then shut it down and exported it, moved it to VMH2, and imported it successfully. So, there doesn't appear to be anything wrong with the fundamental export-import procedure, I just can't export our actual production VM server to the other VMH.

An additional complication is that since VMH2 is core, there's no GUI, so I am running the Hyper-V manager on VMH1. Can't find any error messages or anyplace where the errors would be written on either server.

What do I do?

Hyper-V - Can not install Integration Services

≪ Previous: Hyper-V "Failed to import a virtual machine"

Hello, people!

Disk2vhd: I used to try to migrate a physical server (SF01) virtual server (SV01).
The SF01 is a Windows Server 2003 Standard Edition SP2.
Physical server (SF02), Windows Server 2008 R2, was installed Hyper-V role.

I created the VM, and set the vhd to SV01. And I started it.

To my surprise! Both in normal startup mode or safe mode with networking. After logging in, there is a

screen for the registration of the license.
If you do not activate the license, a logoff occurs.

I ran the winproductkey both the SF01 as the SV01, and the product key is identical.
And when I try to activate the license for the same product key (Change Product Key option), back to the License Activation screen!

When activating the license of SV01 with the same SF01. It displayed an error!

Another problem:
In safe mode without networking. Can not login (SV01), but I can not install Integration Services.
But, the file C: \ windows \ vmguestsetup.msi.log is mentioned some errors:
Failed to connect to server. Error: 0x8007043C
Failed to connect to server.
MainEngineThread is returning 1601

What are the procedures to properly install the Integration Services?
And also to Activate License?<object height="0" id="fb6b5838-0b89-8fa2-e9bb-09bc3ababd9e" style=";left:0px;top:0px;" type="application/gas-events-cef" width="0"></object>

≪ Previous: Hyper-V - Can not install Integration Services

I have a server runing windows 2008 R2 SP1 with hyper-v role. I have a windows 2008 R2 SP1 guest running that loses network connectivity. I am getting this event message when the issue happens. Event Id 7042

The TCP/IP NetBIOS Helper service was successfully sent a stop control.

The reason specified was: 0x40030011 [Operating System: Network Connectivity (Planned)]

I have disabled the power management option on the network adapter on the hyper-v server and rebooted but I am still getting network connectivity loss. I have tried hotfixes that is supposed to fix the issue but the install says it is not for my computer. Any suggestions on this would be helpful.

Thanks

I have two XP / SP3 vitrual machines, and on each one, after I dismiss the "found new hardware" wizard, and try to install the Integration Services, I receive the "A previous installation og Hyper-V integration services has been detected"

I click OK to "upgrade or repair", and I get the following error message:

My event viewer doesn't seem to have any relevant information.

Ideas?

Hello all. I've gone in circles on search engines and here trying to find an answer. It's shocking how common this problem is, that it affects servers so should have a very high priority for somebody at MS to look into, and yet notbody has ever found an answer that I can see. Most posts I see are older though so I am hoping July 2013 has some answers :)

In short, I believe the problem may have begun 2 days ago when we replaced the building's only network switch with a new Cisco 2960-S switch. These are simple GbE switches that work out of the box so nothing new has been configured. I do intend to further configure at some point but this was an emergency replacement.

Yet the Hyper-V host (2008 R2) is now showing VMSMP Event ID 28 messages in the System Log at a rate of about 30,000,000 entries per day. Any time I look, there are about 46,000 entries, if I Clear Log and count to 10, refresh and I have between 3000-5000 more entries. I guess 46,000 is the limit before older ones start ot disappear.

The VM's appear to be unaffected, but because I exclusively RDP to just the host machine and use Hyper-V manager to access the VM's, I can't be sure. No users have complained yet.

However my RDP session freuqntly needs a refresh due to disconnect so clearly this problem affects the host.

NIC setup is:

4 physical NIC.

4 VMs

VM1 is the primary AD DC, and shares the NIC with the host. The other 3 NIC's are dedicated to the other 3 VMs.

The 4th VM though is not in use yet, so in theory the 4th physical NIC is free, however I'm afraid to try to use it for VM1 (thus breaking the "share with host" relationship) because being a little fresh on these subjects I"m not sure what that'll do to the IP address of the AD DC, which if I mess that up brings down the network for the users.

Of course I'd rather solve the VMSMP problem but as a workaround, can I just assign the 4th NIC to the VM1? I'm doing this remotely too, so don't want to uncheck "share with mgmt OS" and cut myself off...

Btw, I did try to set static MAC addresses for each VM - no change. This has never worked for anybody in any post/thread I've seen either if that says anything.

Totally lost, please help!

≪ Previous: VMSMP Event ID 28 filling System Log

Hi guys,

I'm looking at drawing up simple network diagrams of the virtualised servers and IP addresses.. To make it easier to remember the IPs of the virtual machines and the hypervisor, which can get confusing at times. Is there any basic starting diagram I could use to give a simple, clear visual representation of the virtualized network, which I could then use as a template for drawing custom network diagrams for my clients.

nb. I dont have visio, but I have photoshop my plan would be to get an image file and just edit this as required.

thanks,

Import and Export of VMs from remote file server won't work for Windows Server 2012

≫ Next: Tape Drive In Child Partition?

≪ Previous: Drawing Network Diagrams For Virtualized Networks.

I have three different Windows Server 2012-based Hyper-V networks currently running. I ran these environments originally on 2008 R2 Hyper-V. I only recently built Windows 8 managmenet workstations to to remote management of these domains. In each of the domains, there is a file server that contains shares to export and import VMs form the Hyper-V hosts. I just noticed that I cannot import or export VMs from the file shares when I remotely administer the Hyper-V hosts.

In the import wizard I can browse through the share and select the VM folder, but when I hit Next in the wizard I get "The folder (the remote file server path) could not be found. You might not have permission to access it."

The export wizard gives more or less the same error, but with an added possibility: with no changes happening on the network during my tests, the export will sometimes run with no error and export to the remote file server, but later on when I test it again it will resume giving access denied errors.

To make remote administration work in in these scenarios the usual fix is to to a constrained delegation on the hyper-v host of the cifs service to the remote file server. I did this on the old 2008 R2 Hyper-V hosts and didn't have any notable issues. I have made the same delegation for the Server 2012 Hyper-V hosts but I do not get the expected good result.

What's strange is that nonoe of the three Server 2012-based networks I am running will do the delegation correctly. I haven't seen any web pages recommending any other settings to make this work. Is there some extra step to make Hyper-V 3.0 do the delegation successfully?

≪ Previous: Tape Drive In Child Partition?

I have been working on documentation on how to install Hyper-V on a HP ProLiant, and have it pretty much finished.. But one thing is baffling me...

Server has Windows 2012 and Hyper-V installed as the Management OS. In Hyper-V, I have one virtual Windows 2012 server that is domain controller / DHCP / DNS for the network... The Management OS is a domain member server and I am logged in as the Domain Administrator.. I set up remote desktop services on the Management OS, assigning it all of the required roles (Connection Broker etc etc).. Then I create a Personal Desktop Collection (again on the Management OS) using a sysprepped Windows 7 virtual machine in Hyper-V. Then the users then log in to the Management OS IP/hostname from the browser to access their Personal desktop.

I have read that some people set up RDS on one of the virtual machines, and assign the virtual machine all the roles, but I dont understand how this can work as the sysprepped machines are sitting on the Hyper-V server.. But I also understand that no services other than Hyper-V should be running on the Management OS... What is the best way to set this up for a small business where only one/two users will be accessing personal virtual desktops..

thanks,

Windows Server 2012 BSOD caused by vmswitch.sys

≪ Previous: How to connect USB external Harddisk to Hyper-v virtual machine

Hello guys,

Situation is the following. I have 2 Windows Server 2012 with Hyper-V installed. We have approximately 10 VMs on each server and these VMs are replicating in both directions.

We had 2 NICs in teaming (switch independent) connected to 1 switch. Interfaces are in access mode.

On Friday evening we added another switch, where we connected the other 2 NICs of each server, so we decrease the load from the 1st switch. We added these NICs to the team. The switches are connected by trunk port.

Today (Monday) at around 11am (maybe higher network load), both servers got BSOD with 3 minutes difference. One at 11:02, the other at 11:05.

On both servers the cause is listed as vmswitch.sys. I did not find any info on this happening in Google. Here is the output from WinDBG:

Hyper-V on 2012 host compressed drive

August 6, 2013, 8:00 am

≫ Next: Is Hyper -V free for big organization

≪ Previous: Windows Server 2012 BSOD caused by vmswitch.sys

I just noticed that on my 2012 host server, the drive where I have been placing my VM hard drives is compressed. I can imagine that this is not desirable on many levels, so I would like to turn off the compression setting for the drive.

What do I need to watch out for? I am thinking that if I shutdown each VM first, before I turn off compression, it should be fairly safe.

Is hyper -V can host 400 virtual machines?

How is it counted for licenses and fees?

We have vmware but it is too expensive so we want to do comparison between hyper -V and Vmware to see the difference for price and functionality and limitations of VMs.

Hyper V Create VM with custom settings using WMI attach VHD

June 8, 2011, 10:18 am

≫ Next: VSS fails on mounting a virtual copy of a LUN

≪ Previous: Is Hyper -V free for big organization

Does anyone have a complete example of how to create a VM that has custom settings and VHD's attached using WMI from PowerShell? (need to use WMI and not the library from codeplex) I have found a lot of partial scripts that create default vm's without vhd's attached and a lot of broken links pointing to solutions. Have also seen reference that it can be done with AddVirtualSystemResources but have not seen any examples. Here is what I have so far, and thanks in advance!

Create VM with no VHD's, and create VHD but don't know how to connect the VHD or create it during the VM creation steps:

#get the current computer name
$currentname=get-wmiobject Win32_ComputerSystem

$namespace=$currentname.name

#create a VHD
$disk = Get-WmiObject Msvm_ImageManagementService -namespace "root\virtualization" -computername $namespace

$disk.CreateDynamicVirtualHardDisk("$env:systemdrive\nameofvhd.vhd", 20000000000)|out-null
$newvm="Test"
$description="This is the Description"
$path="$env:systemdrive\testvmfolder"

# Create a VM

# Get a new instance of Msvm_VirtualSystemGlobalSettingData

$vsgsdClass = [wmiclass]"root\virtualization:Msvm_VirtualSystemGlobalSettingData"
$vsgsd = $vsgsdClass.CreateInstance()
$vsgsd.ElementName = $newvm
$vsgsd.Description = $description
$vsgsd.ExternalDataRoot = $path

# Get the managment service and define the system from the embedded instance
$vmms = gwmi -namespace root\virtualization Msvm_VirtualSystemManagementService

$result = $vmms.DefineVirtualSystem($vsgsd.GetText(1))

if($result.ReturnValue -eq 4096){
    # A Job was started, and can be tracked using its Msvm_Job instance
    $job = [wmi]$result.Job
    # Wait for job to finish
    while($job.jobstate -lt 7){$job.get()}
    # Return the Job's error code
    return $job.ErrorCode
}
# Otherwise, the method completed
return $result.ReturnValue

VSS fails on mounting a virtual copy of a LUN

August 13, 2013, 3:09 am

≫ Next: How to find out the creator who created snapshot on a Hyper-V host?

≪ Previous: Hyper V Create VM with custom settings using WMI attach VHD

I have a HyperV-Server 2012, there are VMs running with following configuration.

Configuration A:

Windows 2008R2 Server x64.
Exchange Server 2010 SP3.
LUN presented via Virtual Fibre Channel.
MailBox created on a LUN.

Configuration B:

Windows 2012 Server x64.
Exchange Server 2010 SP3.
LUN presented via Virtual Fibre Channel.
MailBox created on a LUN.

We are performing backup tasks related to LUN, like taking snapshot, mounting, restoring etc.

In configuration A we are successfully able to do the above operations, but in configuration B we are facing VSS issues while mounting the snapshot.

Volume Shadow Copy Service error: Error calling a routine on a Shadow Copy Provider {5f466535-9c6c-4b33-be9f-8f3147381cf5}. Routine details Routine ImportSnapshotSet failed with 0x800423f8 [hr = 0x800423f8, An expected disk did not arrive in the system.].

Does anyone has any idea why this issue is being hit only in Windows 2012 Environment?

NOTE: Both the configurations A & B are working fine in VMDirect(VMware). This issue is being faced only in Virtual Fibre Channel(HyperV).

HyperV planned failover fails reversing replication. FQDN is truncated.

August 13, 2013, 7:08 am

≫ Next: Replicate Hyper-v Virtual Servers

≪ Previous: How to find out the creator who created snapshot on a Hyper-V host?

Hi,

I am having an issue with planned failover between two hyper-v hosts

- HostA and HostB are on the same domain
- DNS is all fine both servers can ping each other using FQDN and hostname
- Using kerberos authentication between hosts

I can go to the "other" host fine and manually start the reverse replication fine, it just will not do it automatically as part of the planned failover.The same thing happens regardless of which way I am failing over HostA to HostB or HostB to HostA

A screenshot probably explains it best, notice the second highlighted section is missing the .LOCAL

I have only found one other reference to this issue http://social.technet.microsoft.com/Forums/windowsserver/en-US/af8704b3-6623-40ba-af78-567f69a9eca1/hyperv-2012-replication-planed-failover-failed-to-resolve-the-replica-server#c7a08d0e-479a-40d1-8b64-fac309741e21

Replicate Hyper-v Virtual Servers

August 13, 2013, 8:42 am

≫ Next: Removing for dependencies: kmod-microsoft-hyper-v

≪ Previous: HyperV planned failover fails reversing replication. FQDN is truncated.

Hi.

We currently have a small SAN and a 2 node 2008R2 Hyper-V cluster with a couple of CSV's. Just recently we had a fire in the building and this has made everything sit back and think a little bit more about DR.

Up the road we have another building and a 100mb fibre pipe between the 2. As a quick solution we would like to stand up a single server running Hyper-V with a fair bit of storage. Then replicate the virtual machines here in case of DR.

I would like to know if anyone has done something like this, and if there is a best way to replicate the machines without turning the live ones off. We would only replicate the mission critical ones, as all the others are backed up and tapes off site.

What commands did you use or 3rd party software is recommended?

Or is the simple answer to upgrade to Server 2012 Hyper-V?

many thanks

Olly
