Good links
Forward kvm host qemu vnc with ssh
$ ssh -L 5900:localhost:5900 <kvm-host-ip> -N
List all guests even not started
# virsh list --all
Guest migration
Dump config
# virsh dumpxml --migratable <guest-name> >guest-name.xml
Restore guest config on new host
# virsh create guest-name.xml
Create guest
# virt-install --name <name> --connect qemu:///system --virt-type kvm --memory 30720 --vcpus 8 --nodisks \ --os-variant opensuse42 --network bridge=br0 --boot=hd --pxe --vnc --vnclisten=localhost --vncport=5900
Attach block device to guest
Create xml config for example vda.xml
<disk type='block' device='disk'>
<driver name='qemu' type='raw' cache='none'/>
<source dev='/dev/sda5'/>
<target dev='vda' bus='virtio'/>
</disk>
Permanently attach block device to already existing domain
# virsh attach-disk <domain-name> vda.xml --persistent
