If I boot from the ISO "CentOS-5.5-i386-bin-DVD.iso" from the CentOS FTP, the instance will hang at the same point as booting the instance from the virtual disk. It is solved by disabling SMP (using just 1 CPU).

This is my KVM commandline:
kvm -daemonize -enable-kvm -smp 8 -smp 8,cores=4 -m 2048 -vnc 0.0.0.0:4 -usb -usbdevice mouse -drive file=/dev/vservers/test10,index=0,media=disk,if=virtio -drive file=/root/iso/CentOS-5.5-i386-bin-DVD.iso,index=0,media=cdrom,if=ide -boot order=d -net nic,vlan=0,macaddr=00:77:95:ab:91:be,model=virtio -net tap,vlan=0,ifname=test10,script=/usr/share/vcluster/ifup.pl,downscript=/usr/share/vcluster/ifdown.pl -net nic,vlan=1,macaddr=00:77:95:e9:05:5c,model=virtio -net tap,vlan=1,ifname=test11,script=/usr/share/vcluster/ifup.pl,downscript=/usr/share/vcluster/ifdown.pl -monitor unix:/tmp/test1,server,nowait -pidfile /tmp/test1.pid

I am running KVM 0.14.0+noroms-0ubuntu4.3 (compiled on 10.04 using source debs) on Ubuntu 10.04 LTS with kernel 2.6.32-33-server. I know this is probably not a supported combination, but since this is the same problem, I thought it might be useful to still answer on this bugreport.

Attached is a VNC screenshot. It is already hanging for about 15 minutes on this point.
