[libvirt] starting vm using virsh somewhat fails

Hi all, I have started a vm using virsh create domain.xml and it starts for a second and then its destroyed automatically. When I do xm create -f <xm cfg> it works fine. I don't know if this is relevant but virsh net-list --all Name State Autostart ----------------------------------------- default inactive yes virsh net-start default error: Failed to start network default error: Failed to open file '/etc/sysconfig/system-config-firewall': No such file or directory Can this be the problem? Why do I need /etc/sysconfig/system-config-firewall?
