Re: [XenPPC] libvirt & virt-manager/virsh status - working - update

[Christian Ehrhardt <ehrhardt@xxxxxxxxxxxxxxxxxx>]

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:
