Nested Virtualization Of Hyper-V 2K8R2

Nested Virtualization Of Hyper-V 2K8R2

[Jim]

Hi,

I've worked with KVM for quite a while now but have come across a 
problem when trying to run some W2K8R2 VMs where I want to also run 
Hyper-V on those VMs - nested virtualization.

I've researched and checked the obvious AMD processor with the enable 
nested flag, running a kvm guest with the nesting support enabled etc. 
which did allow me to add the Hyper-V role to the VM but when it 
reboots, the machine hardware lists a problem with the VM machine bus 
and no hyper-v VMs can be created.

 From what I've read through from lurking on the list and reading the 
archives, I'm not sure whether the problem is that KVM is not ready to 
support Hyper-V yet or if I'm doing it wrong.

I'd be very thankful if someone could say if I'm hoping for too much 
right now or point me where to go to find some details on what I'm  
doing wrong and how to do it right.

Thanks
Jim

What's the error message?

It's likely a kvm bug.

Hi Avi,

There are 2 errors listed on the device manager.

Well, no idea.  It will have to wait until someone takes the time to
debug it.

error compiling committee.c: too many arguments to function

Re: Nested Virtualization Of Hyper-V 2K8R2

[Jim]

OK, this sounds like I am doing it wrong then.

The system is a Quad-Core AMD Opteron(tm) Processor 1354 running Ubuntu 
11.04 server with kernel 2.6.38.

The KVM starts with -enable-nesting and a ps of the running process 
shows this is set.  The Hyper-V role would not install until the 
-enable-nesting was appended to the command line, so I was using this as 
the confirmation nested virtualization was active.

I have tried the VM with 1 vcpu and with 2 vcpu and also with the -no 
options from http://www.linux-kvm.org/page/Bugs.

Is this the Ubuntu version of KVM is too old for what I am trying to do ?

Can you share the qemu command line you used to start the VM?

I also had issues with Hyper-V. But at least the root-domain should boot
up without problems. I also started a Linux guest inside but that got
stuck at some point in the kernel boot process. I havn't debugged that
further yet, though.

Hi Joerg,

Sure, the KVM command is :

This is missing a -cpu parameter. Please try again with adding
'-cpu phenom,-hv'. This is the combination I used during testing and
development.
