Note: the host is running 7.4 and I compiled with ./configure --prefix=/usr/local --cc=gcc-3.4 --host-cc=gcc-3.4 --kernel-path=/usr/src/linux-headers-2.6.20-16-server/ > The host has a second guest running ubuntu dapper linux 2.6.15-28-686 > qemu -vnc :1 -kernel-kqemu -daemonize -no-reboot -monitor unix:/vservers/qemu/mail1/mail1.sock,server,nowait -boot c -hda /dev/sdc -net nic,vlan=0,macaddr=00:16:3e:00:0f:10 -net tap,vlan=0,ifname=br0-mail1,script=/etc/qemu-ifup-br0 -m 512 Just an idea, if your host is SMP too: try booting the guest kernel with "notsc" param or setting qemu's affinity to a single CPU using taskset. It may help or not :) Cheers, Andrzej
