Subject: nova-compute on VirtualBox with qemu<br>
To: <a href="mailto:openstack-operators@lists.openstack.org">openstack-operators@lists.openstack.org</a><br>
<br>
<br>
I'm using Essex on virtual box, and am having some issues getting<br>
nova-compute to not hate me that much.<br>
The error I'm getting is: libvir: QEMU error : internal error Cannot<br>
find suitable emulator for x86_64<br>
Running the same steps as in [1] seems to reproduce the same behavior.<br>
<br>
The VB guest is 12.04.<br>
<br>
nova-compute.conf has:<br>
[DEFAULT]<br>
libvirt_type=qemu<br>
<br>
I guess my question is - where do i supply libvirt / nova the magical<br>
'disable accel' flags? (i.e. '-machine accel=kvm:tcg', which seem to<br>
make qemu happy).<br>
<br>
<br>
TIA,<br>
