Re: Nested Virtualization Of Hyper-V 2K8R2

[Jim <jim@suresafe.co.uk>]

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 ?
