*Hi Andi* *Here is an extract from an installation guide for Essex which describes a bit different approach to the problem solution rather than command line customization:* When running Nova within a vmWare/VirtualBox/etcThe default libvirt-bin provided by the official Ubuntu repository (ver. 0.9.8-2ubuntu17) has a problem with pure software virtualization fallback which doesn’t allow it to run instances within a virtualized machine. However this problem is fixed in the latest version of libvirt which can be installed from the PPA with the following commands
# apt-get install python-software-properties # add-apt-repository ppa:ubuntu-virt/ppa # apt-get update && apt-get upgrade The packages proved to be working have the following versions qemu-common 1.0+noroms-20120330-0ubuntu3 qemu-kvm 1.0+noroms-0ubuntu13 qemu-utils 1.0+noroms-20120330-0ubuntu3 libvirt-bin 0.9.9-3ubuntu1~ppa1 libvirt0 0.9.9-3ubuntu1~ppa1 Also make sure you have the following line in /etc/nova/nova-compute.conf --libvirt_type=qemu You can also try running /usr/bin/qemu-system-x86_64 manually, this might help to troubleshoot the problem. This binary might have some dependencies missing when being improperly packaged. Hope this helps.
