Completed CentOS 5.4 perfect install from howtoforge.com (ISPConfig 3). I have ISPConfig 3 deployed with a handful of sites. I installed xen:

yum install xen kernel-xen

i installed the recommended (linuxtopia.org) virtualization packages and started libvirtd

yum install virt-manager libvirt libvirt-python libvirt-python python-virtinst

i have damn small linux .iso in /root

virt-install --name damnsmall --ram 16 --file=/var/lib/xen/images/damnsmall.img --file-size=1 --vnc --cdrom=/root/current.iso

yields the error: ERROR Host does not support any virtualization options

i have also tried this from GNOME (virt-manager) and i cant even add a connection. i read somewhere i need to reboot with the xen kernel--i dont think i want to do that--though, not really sure why. i need to keep ISPConfig untouched.

Thanks in advance, and let me know if you need additional info
