Yes you can install in a VM.
To support nested VMs with nova you need this basic config change:
openstack-config --set /etc/nova/nova.conf DEFAULT libvirt_type qemu
There are other caveats to note with nested VMs...
They will be the much slower TCG variety, and note you should
provide lots of memory to the top level guest, as the OpenStack
created guests default to 2GM RAM with no overcommit.
To avoid Folsom issue https://bugzilla.redhat.com/show_bug.cgi?id=858216
you'll need to make this config change:
openstack-config --set /etc/nova/nova.conf DEFAULT libvirt_cpu_mode none
If you're running with libvirt < v0.9.13-66 then you'll need to do
this to avoid https://bugzilla.redhat.com/show_bug.cgi?id=813735
ln -s /usr/libexec/qemu-kvm /usr/bin/qemu-system-x86_64
service libvirtd restart
service openstack-nova-compute restart
thanks,
Pádraig.
