get-vm shows integration services version as 0.0

We're running Hyper-V 2016, and have upgraded the VM version of most machines to 8.0, but still have some at 5.0.  There's a mix of generation 1 & generation 2 VMs.

Now, when we run:

get-vm | ft Name, IntegrationServicesVersion

it returns the Integration Services Version as 0.0 for ALL VMs, including the Linux VMs.

In Failover Cluster manager, the Integration Services versions are correct.

A search only returns a single other incident like this, and the fix then was to apply a hotfix that has since been expired/removed.

Solved,
I have solved this now
http://www.netexpertise.eu/en/systems/windows/hyper-v-error-loading-operating-system-after-running-disk2vhd.html

I was selecting the wrong disk

I also had to follow
https://web.archive.org/web/20140831151616/http://www.xtralogic.com/testdisk_rebuild_bootsector.shtml

Hi all,

I need to convert a server 2003 VM from VMDK to VHD, I am currently using StarWind v2v, the conversation goes fine, when I setup the new VM up in hyper-v I get error loading operating system.

1. The VM is set up as a generation 1 VM with IDE no networking,

2. The 2003 os is 32bit SP2 which I found is the minimum for support in hyper-v

3. The host is running 1607 W10, the conversation took place of a different system running 1607 as well.

I have tried

Doing a generation 2 VM

following the below link, which only left me with a raw disk.

how to let hyperV machines see each other through internal IP ?

hi guys, I have about 4 hyperV machines

Host OS - internal nic 10.0.0.1 and one external nic to internet. NAT is configured (automatically using the RRAS setup wizard)

VM Ips : 10.0.0.11, 10.0.0.12, etc...

VM gateway set to 10.0.0.1

the VMs can access internet. the host OS can ping the VM IPs

but VM1, can't ping/telnet VM2, and VM3 and VM4 and vice versa (via computer name or the internal IPs)

. If I remove RRAS from the host OS, the VMs can see each other. but with RRAS (NAT) setup, they can't. is there another setting I have to do in RRAS or HyperV ?

any help is greatly appreciated

Internet connection lost on Hyper-V Virtual Machine after connecting to VPN

November 24, 2016, 8:36 am

Sorry, I am entering the lion's den here and I apologise for my lack of knowledge here.

I am new to a job, and we use HyperV to connect to various customers using different VMs.

For one of our customers, I can go into the VM and from there access external internet sites such as Google, Bing etc.

The connection on the VM appears to use a Local Area Connection to access the internet.

When I'm on the VM, in order to access the customer's corporate system, I have to connect to a VPN, set up in a Cisco VPN application.

The problem I have is that while I can connect to the corporate application, I lose the ability to connect to external URLs.

For one of the problems I'm investigating, I need to be able to access an external URL, and not being able to do so means I have to keep bothering the customer, instead of being able to do the full end-to-end test myself.

It might be that connecting to the VPN loses the internet connection, but I do recall that when in my old job, I could work from home, and connect to work via a VPN using a Cisco VPN client, and access corporate applications, and external URLs at the same time.

However, I don't know enough about VPNs to know if that difference is just down to the way the VPN has been configured by the customer (e.g. disable internet connection).

So I thought I'd ask here for advice.

Any help much appreciated.

Currently I face a problem on my Hyper-V host that is my Windows and Linux VMs IP address will be loss after I restart the VM. I need to manual enter the IP address again every time it restarted. After I found out some articles, most of the articles are mentioned the integration services are outdated and need to be update. Therefore, I have update my Hyper-V hosts also installed the latest integration services to one of my Windows VM and it works fine. For Linux, I installed the Linux integration services 4.0 but after I restart the VM's IP address is still loss. Any idea or anyone had encounter this issue before? 

Thanks and appreciated.

Hi,

I have a Server 2012 R2 plus two windows 10 clients clients. I setup two virtual switches (one external and one internal). I'm planning to use the external on the server machine for internet access and have the server machine act as a router/gateway for the Windows 10 client machine, I'd appreciate any advise help on how to setup this environment the best way?

I'm trying to enable live migration on my Windows 2012 R2 hyper-v server, and it keeps failing. When I try through the GUI, I get an error that says "Error applying Live Migration changes. Failed to modify service settings."

If I try to enable it via the Enable-VMMigration powershel cmdlet, I get the following result:

Enable-VMMigration : Failed to modify service settings. The operation cannot be performed while the virtual machine is in its current state. At line:1 char:1 + Enable-VMMigration + ~~~~~~~~~~~~~~~~~~ + CategoryInfo : InvalidOperation: (Microsoft.HyperV.PowerShell.VMTask:VMTask) [Enable-VMMigration], Virt ualizationOperationFailedException + FullyQualifiedErrorId : InvalidState,Microsoft.HyperV.PowerShell.Commands.EnableVMMigrationCommand

I've removed & reinstalled hyper-v on the server, but with no luck. Any suggestions as to how to resolve this?

Why is the hypervisor running even after Hyper-V is uninstalled ?

Hi,

I'm running into a weird issue on my Lenovo Z51 laptop. Its equipped with an intel i7 processor and is running Windows 10 Pro (Build 14393). I had Hyper-V installed on this laptop with all kinds of VMs running for a while. Then I got a VMware license and decided to uninstall Hyper-V. I uninstalled Hyper-V by going to "Turn Windows Features on or off", unchecking all options under Hyper-V and then rebooting the machine on the prompt.

After the reboot, I installed VMware but when I try to start the VMs, it gives me an error that Hyper-V is still running. In the "Turn Windows Features on or off", the box for Hyper-V is unchecked. However, when I look at msinfo32 it still says:

>> "A hypervisor has been detected. Features required for Hyper-V will not be displayed." <<

Coreinfo.exe says the same thing:
Intel(R) Core(TM) i7-5500U CPU @ 2.40GHz
Intel64 Family 6 Model 61 Stepping 4, GenuineIntel
Microcode signature: 00000021
HYPERVISOR      *       Hypervisor is present <---------
VMX             -       Supports Intel hardware-assisted virtualization
EPT             -       Supports Intel extended page tables (SLAT)

I did a lot of hunting and already tried the below assuming some corruption:
"SFC /scannow" & reboot,
"dism /online /Cleanup-Image /RestoreHealth" &  reboot
"bcdedit /set hypervisorlaunchtype off & reboot

None of these worked.

Why does it say the hypervisor is present when I have uninstalled Hyper-V ? What can I do to fix this and run VMware ?

VMs can ping eachother but not host or default gateway

November 28, 2016, 12:59 am

The VM guests can ping each other but they can't ping not the Hyper-V host server or even the router/default gateway. The system was originally setup on a test network with a different router/default gateway where it worked, after being moved to the production network I've hit this issue.

  • All Hyper-V virtual switches have been deleted and recreated.
  • Internal DNS isn't working because one of the VMs is the domain controller (which again can't ping the default gateway)
  • Ipconfig /all only shows the production network default gateway, not the test network gateway
  • There is only one virtual NIC adapter on the Guests after the hyper-v virtual switches were all deleted and production network ones created.
  • The guests are on a dedicated NIC adapter on the host, not sharing with the host
  • Two different host NIC ports and cables tried
  • There was original NIC teaming on the guests, but its been disabled.
  • Domain firewall is disabled
  • No external physical firewall currently in place
  • nvspbind isn't helping, or at least I'm not seeing anything that I should delete there.
  • nvspscrub doesn't seem to work on Windows Server 2016.

So the host can ping the default gateway fine, so can a laptop, if using an external DNS in the IPv4 properties they can even access the internet bypassing the internal DNS.

How does Failover Cluster Manager Choose the adapters to be used?

November 28, 2016, 8:31 pm

I have a 2 node 2012 R2 Hyper-V setup that i am trying to configure Hyper-V HA. The network setup for both nodes are as follows:

Total: (8 x Ports):

4 x Adapters - (Teamed:Production/VM external access) @ 3 x 1Gbps and 1 x 10Gbps

Teaming Mode: Switch Independent 
Load balancing mode: Dynamic 
Stanby adapter: None (All adapters active) 
Network: 192.168.100.x

2 x Adapters - iSCSI (MPIO) @ 10Gbps 
Network: 192.168.115.x

1 x Adapters - Cluster (Managment,VM Migration and replication) @ 10Gbps 
Network: 192.168.100.x

1 x Adapters - Phone Network @ 1Gbps 
Network: 192.168.104.x

The problem is that the failover and cluster manager (FCM) is selecting the Production network for one node and the cluster for the other. I want the cluster network to be dedicated for managing the hyper-v, migrations and replication.

I have configured the adapter order on the nodes as follows:

vEthernet (vSwitch_Production) 
Team_Production 
NIC1 - Production 
NIC2 - Production 
NIC3 - Production 
NIC4 - Production 
NIC5 - Cluster 
NIC6 - iSCSI 
NIC7 - iSCSI 
NIC8 - Phone

Can anyone please comment as to if this network setup will work with Hyper-V HA and, how I can ensure the correct adapters are selected by FCM?

Is there a way to pause replication so merging can complete?

Hello,

I noticed if it has been a long time since replication has occurred, when you resume replication you get a big avhdx file.   Replication looks like it completed but the merge process begins but gets interrupted as the replication occurs again.   The only thing I know to do is to shut down the virtual machine that is having the issue so there is no replication and the merge can complete.   Is there a way to do this without shutting down the VM so you can get rid of the avhdx file?

If I just pause replication - replication and MERGING stops.  I need to stop replication but force the merge.

Hyper-V Manager (RSAT Windows 10) Access denied. Unable to establish communication between '' and ''

Hello Guys, 

I'm having problems when trying to use Hyper-V Manager (RSAT Windows 10) to remotely Manager a Hyper-V 2012 Evaluation Server (Core). I am receiving the message when connecting to the server from my Hyper-V Manager. Access Denied. Unable to establish communication between 'Admin PC' and 'Hyper-V Server'.

Both systems are on the same domain, I have enabled both remote management and remote desktop on the server and I have added the domain account that I am using to remote onto the server into the server's local Administrators group and RemoteDesktopUsers group. I can remote desktop onto the server and administer it however Hyper-V Manager doesn't seem to be working. 

I've done some research and can see that there are a few articles for Windows 8 RSAT for changing the DCOM settings to allow AnonymousUsers to RemoteAccess however I've applied this fix and it's still not working. 

Really stuck with this one now, suggestions? 

Thanks, Bo.

    Hi.

    I Have hyper-v on windows 2012 R2, witch storage pool (4 disk) na 20 TB thin provisioned volume with deduplication.

    On that volume i have one 8TB vhdx file (fixed size). When I try resize that vhdx disk  i got disk queue (on that volume) at about 5-7 with 100% disk activity, and after several minutes i got Event ID 15282 (Filed to resize the virtual disk) and ID 27294.

    Its any possibility to limit disk I/O impact during creating or resizing vhd(x) file ? Because looks like the errors occurred when disk queue becomes too high.
