Re: [Qemu-devel] vt-x support for qemu

[Anand J]

Hi,

I have the following setup. I'm running qemu in software mode, installed
KVM inside qemu. And on top of that I need to run qemu again but with kvm
enabled. But I'm getting the following error when I try to do that.
Can somebody please help me with this?

KVM internal error. Suberror: 1
emulation failure
