Hi Daniel,
libvirt never directly stores its XML files when talking to Xen - it
always uses one of the two Xen formats as the master database instead.
...snipp...
On Xen> 3.0.3 libvirt uses the native Xen APIs, which result in
the
files being stored in /var/lib/xend/domains instead.
So if I change the files in /var/lib/xend/domains manually, the changes
should stick, right? I tried that and occasionally the files revert to
the previous version.
Could it be that the respective VM (or virt-manager?) must not be
running while changing the domain configuration files? Does libvirt or
xen store the domain configuration in memory while the machine/gui is
running and write it back to the configuration file when the machine/gui
shuts down?
Thank,
Arik
