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: --------------------------------------------------------------------------------------------------------------------------------------------- $ ./nimbus-cloud-client-022/bin/cloud-client.sh --run --name testimage --hours 1 Launching workspace.
