Hey,
Restarting libvirt service won't crash your VMs.. Might be that during the migration
libvirt got crashed, did you try to restart only vdsm?
Can you attach your vdsm.log? Maybe I'll be able to point this issue to a specific bug
and find the reason for this failure..
Thanks

Hi Yaniv,
the config on all servers were fine (with SSL).
I had to reboot the "old" hypervisors to make migration from new hypervisor
possible (restart of libvirt would crash my VMs ;) ),
was a bit hard as I hadn't any other VM slots were I could migrate to..
Just have this behavior with oVirt 3.0 environment, oVirt3.2 with minimal F18
nodes works fine here.. strange.
Want to give you feedback here as you answered very quickly.
Thanks again!
Cheers,
Sven.

Hi,
check your conf files, if you use secure connection to host you should check
the parameters:
in /etc/conf/vdsm/vdsm.conf - check that "ssl=True" under [var]
in /etc/conf/libvirt/qemu.conf - check for spice_tls =1
and in /etc/conf/libvirt/libvirtd.conf - auth_tcp and listen_tcp are not
declared (under a comment).
to verify, restart vdsm service and run - vdsClient -s 0 getVdsCaps [-s for
secure]. if it returns, the configurations are good.
for unsecure connection:
in libvirtd.conf you should have auth_tcp="none" listen_tcp=1 in
/etc/conf/vdsm/vdsm.conf - check that ssl=False in
/etc/conf/libvirt/qemu.conf - check for spice_tls=0
and again, to verify - vdsClient 0 getVdsCaps , if returns we're fine.
Please attach the results.
If it's not the issue, please attach your vdsm.log to check it more
specifically.
Regards,
Yaniv Bronhaim.
