Hi,
The libvirt.org FAQ says that "virsh edit" is the
recommended way of updating the libvirt xml.
If a change has to be made to many VMs "virsh edit" is
tedious, time-consuming and likely to be prone to careless
errors.
Is there a command line approach to updating multiple
VMs?
How about:
for g in guest1 guest2 guest3 guest4; do
virsh dumpxml --inactive $g
/tmp/g.xml
# do whatever sed/etc commands you
want here
virsh define /tmp/g.xml
done
(or something like that, anyway :-)
The "sed, etc." is a mistake since XML does not have guaranteed format.
I suppose XMLStarlet could be used.

Yeah. sed is just my general purpose "replacement for editing by hand"
token ;-)
Something that is xml-aware would obviously be a much better choice.
