[Qemu-devel] [Bug 1387881] Re: qemu fails to recognize full virtualization

[Chris J Arges]

I can reproduce this in a VM:
1) boot a clean cloud images (uvt-kvm create lp1387881)
2) apt-get install virtinst
3) sudo virt-install --name juju-bootstrap --ram=2048 --vcpus=1 --hvm 
--virt-type=kvm --pxe --boot network,hd --os-variant=ubuntutrusty --graphics 
vnc --noautoconsole --os-type=linux --accelerate --nodisks -d

You'll get the following:

$ sudo virt-install --name juju-bootstrap --ram=2048 --vcpus=1 --hvm 
--virt-type=kvm --pxe --boot network,hd --os-variant=ubuntutrusty --graphics 
vnc --noautoconsole --os-type=linux --accelerate --nodisks -d

  I haven't been able to get much out of libvirt as the kvm instance
  never starts.
