Hi,
I am using a Cluster with proxmox 3.4.9
The kernel on the proxmox hosts is 2.6.32-37-pve
I store the vm images in a ceph-hammer cluster
Recently I changed some Linux Machines to virtio-scsi driver from pure virtio driver so I can use the fstrim feature from time to time on the vms.
Now I notice the virtio-scsi vms are crashing randomly, maybe once in a week while the virtio vms are rock-solid and stable
In the crashed machines I can see nothing. The console is black and they are frozen. I also cannot reproduce the issue, not even under high load.
The vms with virtio are running 3.16.0-0.bpo.4-amd64 on debian wheezy. This kernel is needed for trim support
Any ideas what might go on or how I can debug that problem ?
