Package: ganeti Version: 2.15.2-1~bpo8+1 Severity: normal Dear Ganeti maintainers,
I get random freeze on kvm guests in a Jessie Ganeti cluster. Last time it happened 2 times on the same guest at one week of interval. Each time the guest only give ping response but nothing more and it get back to work only after a `gnt-instance reboot`. I did not find trace or error in log files in the guest or in the hosts. I use ganeti and drbd packages from jessie-backports and kvm and kernel packages from jessie archive. The guest is a Debian Wheezy system but it got trouble on Debian Jessie guest too. One month ago I already post a bug report against the linux package about disk lock on some Jessie guests in the same cluster: - https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=870471 In that cases I got something on the guests kernel logs so maybe it's a different issue, maybe not… Any idea of how I can troubleshoot this issue? Is there any log file to see the output of qemu-kvm for each instances? Should I use a kernel and qemu-kvm package from jessie-backports too?
