Hi all, I've got some problems to make work oVirt. I've installed a Fedora 10 VM the lightest possible (nothing checked, even based) and installed after some packages (wget, sudo, acpid,...) and updated the system.

Hello, I am having an issue with libvirt in my Nimbus cloud setup. When I use the Nimbus VM creation test scripts on a VMM node (using libvirt), the VM is created without a problem. However, when I attempt to create a new VM using Nimbus (which then tries to create the VM on the VMM node), I encounter the following error:

I checked the virt-manager logs, and saw this appearing immediately after I tried to proceed:
