Hello all,

We see (since a few weeks) that two of our windows guest kvm machines are sometimes hanging (between intervals of 5 a 6 days).

We see at the status graphics on proxmox that disk and network are stopped or crashed (dropped to 0), the guest O.S. is still running (we see CPU usage), no screen output is given, the vm itself seems to be non responsive.

A simple stop/start clear things up, but it's frustrating :)

We use viritio network / disks to speed things up, the latest virtio drivers 0.1-100 are used.

Is there a way to debug this, so we have a clue what's going on, we see nothing the in guest O.S. itself, and nothing in the proxmox logs.

Regards,
Tom
