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.
