dear community, when run "virsh list --all", get below return: Id Name State ---------------------------------- do it have to have a list domains known to libvirt? how? for the same configuration in the same server, i.e. in the same environment, if run "kvm image.extension", whether image.extension is RAW format or qcow2 format, the VM instance can be started ok. but in virt-manager, RAW format image can't be imported and started successfully, but qcow2 format image converted from the same RAW fortmat image can't, why? in both virt-manager importing and running "kvm image.extension" scenarios, after the RAW format VM instance started successfully, the networking access is different from before, e.g. when run "ifconfig", the interface is eth1, while before it is eth0, very confused. thanks, david su <div class="gmail_quote">On Tue, Nov 20, 2012 at 8:23 AM, Richard W.M.

Use 'virsh list --all' to get a list of all domains known to libvirt. <div> Rich. -- Richard Jones, Virtualization Group, Red Hat <a href="http://people.redhat.com/~rjones" target="_blank">http://people.redhat.com/~rjones</a> </div>libguestfs lets you edit virtual machines.
