I'm using Ubuntu 9.10 as a KVM host. On this host there are 3 Debian 5 guests. When I start all the guests everything works fine, but after 1 to 3 days an exception (Kernel panic - not syncing: Fatal exception in interrupt) occurs.
After this error the KVM is dead, using all (100%) of his virtual CPU.

What is causing this fatal crash? Is it the virtual NIC ('vt82c598' in error message)?
