Hi, I'm running a few Debian Lenny host machines with kernel 2.6.26, in production we use kvm-kmod-2.6.31.5 without any problems. Today I tested to change to kvm-kmod-2.6.33 and everything went just fine up to the moment when a guest exited and when it did the kernel started to log thousands of rows about page errors on the host. modprobe -r kvm-intel (and kvm) and modprobe of the 2.6.31.5 version made the problems go away again. Could it be that 2.6.26 is a little too old kernel to run as host for the newer kvm?
