Re: [libvirt] Using libvirt to obtain mac address of virtual domain
Daniel Berteaud wrote:
If you need to get the mac address from bash, you can use this:
virsh dumpxml myguest | grep 'mac address' | cut -d\' -f2
You'll get one mac address per line (one line per NIC on the guest)
An alternate approach which doesn't depend on the specific manner in
which the XML is pretty-printed follows:
virsh dumpxml myguest \
| xmlstarlet sel -t \
-m "/domain/devices/interface[@type='network']/mac" \
-v '@address' \
-n
This does add an external dependency (see http://xmlstar.sf.net/), but I
find XMLStarlet useful in conjunction with libvirt in other cases -- for
instance, for programatically adding or modifying devices within the
domain XML.
