Hi Apologies if this has been answered previously.
I have a working Openstack setup on my VM lab environment running under Virtualbox. The instances launched run very very slowly (specially CentOS, RHEL, Fedora images). I choose KVM as the hypervisor for Openstack compute node so that means running KVM under virtualbox. However, I needed to put libvirt_type=qemu (instead of KVM) in nova.conf as virtualbox doesn't pass VT-X to guest OSs. Is the slowness caused by this? Should I choose something else like Vmware instead of Virtualbox? Any suggestion? Btw, virtualbox vdi files reside on SSD if this helps. thanks -- Maruf
