I forgot to mention, the host is running debian sid with kernel 2.6.31-1- amd64, and kvm --version reports: QEMU PC emulator version 0.10.50 (qemu-kvm-devel-88) the hosts / and the vm volumes all sit on a lvm volume group, ontop of a md- raid1 mirror of two Seagate 7200.12 500GB SATAII drives. The host is running 7 other guest which all seem to be running smoothly, except both freebsd (pfSense) based guests which seemed to have locked up after this message: ad0: TIMEOUT - WRITE_DMA retrying (1 retry left) LBA=16183439 Though the second freebsd guest didn't seem to use up nearly as much cpu, but it uses up far lower resources than the first. -- Thomas Fjellstrom [email protected] -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
