Hello all,
how can I eliminate question mark from "hanged" VM? ( it happened in shutdown
process via oVirt env. )
Best solution without hypervizor reboot, meaning "power off" , "kill"
or another workaround for that VM .
Will help removing task DB record from oVirt mgmt server - if exists , ofcourse ??
Running gluster 3.7.5 / oVirt 3.5.2 / libvirt-daemon-kvm-1.2.8-16.el7_1.5.x86_64 on
centos 7.1.1503 .
thx a lot.
Pa.
PS: I found similar problem in libvirt library a many years ago ( redhat 5.6 )
https://bugzilla.redhat.com/show_bug.cgi?id=676205
https://bugzilla.redhat.com/show_bug.cgi?id=668438
problem explanation:
http://linux.india365.org/2012/01/libvirt-virsh-cannot-acquire-state-chan...
So it means that this bug was not fixed to this time ??
regs.

This is very interesting, I have seen this error in testing
environment on rhel 7.1 or 7.2.
Can you provide vdsm logs showing the time of the error?

Hello,
some requested outputs
Vdsm generate a huge count of records in time, so I'm not shure if
"hang" time is still included .
Problems occured 17-feb-2016 17:00-18:00 when VM shutdown was requested.
But some performance problems occured a day before ( I'm not shure about
application problem = JAVA = running EBS )
In mail before I attached pointers to bugs with any workaround
killall -9 libvirtd
rm /var/run/libvirtd.pid
/etc/init.d/libvirt-bin restart
which would solve current situation.
Is this workaround safe enought?? Will stay VMs running ???
THX for any help, because I can't reboot hypervizor due huge DB traffic
and no VM migration possibility via oVirt engine. ( mem synchro
overloaded ?? )
Pa.
PS: logs sent directly to RH.
