Just an update now that I finished my look around through libvirt xenppc
support.
working
*monitor load
*remove network interface
*remove hard disk
*access serial console
*define existing xen domains from/to xml file (virsh works
virt-manager has no interface for that)
*run/shutdown domains
partially working
*add network device (work but cause a libvirt bug afterwards)
*add hard disk (work but cause a libvirt bug afterwards)
not working
*sometimes xend hangs and only /etc/init.d/xend restart helps,
there are tracebacks in xend.log
*change number of cpu's
*create virtual network (libvirt bug)
BTW - here iss a small howto for getting existing domains that run with
"xm" to get managed by libvirt:
1. start domain(s) with xm create
2. use virsh dumxml DOMAINNAME
3. store the output in a xml file
4. virsh define XMLFILENAME
Now domains appear in virsh and virt-manager (=libvirt) even if they are
off and can be started via that management tools.
Currently I have no plan to debug the few failing scenarios, so atm just
for documentation reasons the xend & libvirt tracebacks that I found:
XEND
Sometimes:
