[ovirt-users] Some VMs in status "not responding" in oVirt interface

Tue Sep 15 19:30:56 UTC 2015

Hi Christian,

I think of a package similar like this:

qemu-debuginfo.x86_64       2:2.1.3-10.fc21

That allows gdb to show information about backtrace symbols. See
comment 12 of https://bugzilla.redhat.com/show_bug.cgi?id=1262251
Makes error search much simpler - especially if qemu hangs.

Markus

Hi Markus,

gdb is available on CentOS 7, but what do you mean by qemu-debug? I Installed qemu-kvm-tools, maybe this is the pendant for CentOS?

qemu-kvm-tools.x86_64 : KVM debugging and diagnostics tools
qemu-kvm-tools-ev.x86_64 : KVM debugging and diagnostics tools
qemu-kvm-tools-rhev.x86_64 : KVM debugging and diagnostics tools

Regards, Christian

Do you have a chance to install qemu-debug? If yes I would try a backtrace.
gdb -p <qemu-pid>

Hello,

I do not want to hijack the thread but maybe my issue is related?

It might have started with ovirt 3.5.3; but I cannot tell for sure.

For me, one vm (foreman) is affected; the second time in 14 days. I can confirm this as I also loose any network connection to the VM and

the ability to connect a console.

Also, the only thing witch 'fixes' the issue is right now 'kill -9 <pid of qemu-kvm process>'

As far as I can tell the VM became unresponsive at around Sep 15 12:30:01; engine logged this at 12:34. Nothing obvious in VDSM logs (see

attached).

Below the engine.log part.

Versions:

ovirt-engine-3.5.4.2-1.el7.centos.noarch

vdsm-4.16.26-0.el7.centos
