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 ?
