virtualBox support page talks about a race condition. Is this a race in the
guest kernel or user land? It looks like I boot the kernel just fine. the cpu
spikes around init time.

I have a remote system that boots fine when I use:
qemu -vnc :4 -kernel-kqemu -smp 2 -no-reboot -monitor
unix:/vservers/qemu/cms1/cms1.sock,server,nowait -boot c -hda hda1.img -hdb
swap.img -net nic,vlan=0,macaddr=00:16:3e:00:0f:00 -net
tap,vlan=0,ifname=br0-cms1,script=/etc/qemu-ifup-br0 -m 500
But this is not using kqemu and very slow.
When I boot the following, the guest never gets past the init process.
According to top, the guest qemu system uses 101% of the hosts cpu amd x2 3800.
The guest is ubuntu 7.4 running (postgesql, Apache, and ssh)
qemu -vnc :4 -kernel-kqemu -no-reboot -monitor
unix:/vservers/qemu/cms1/cms1.sock,server,nowait -boot c -hda hda1.img
-hdb swap.img -net nic,vlan=0,macaddr=00:16:3e:00:0f:00 -net
tap,vlan=0,ifname=br0-cms1,script=/etc/qemu-ifup-br0 -m 500
Is there a patch for kqemu 1.3.0pre11 and qemu 0.9 to allow accelerated smp
guests?
Is there a way in the proc file system on the guest to see kqemu if is working?
Is there a plan to create a stand alone qemu-monitor that can be attached to a
running qemu process?
Thank you for your time and a great project,

PS. qemu -smp 2 has 90 day's uptime on the production hardware.
