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 can't 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.

I came across this same problem the other day. The problem I had was with a BIOS setting.

In my BIOS, there was an option for "Enable Virtualization", which was disabled by default. I enabled it, and when I booted up my system, I was able to run virt-install with no errors.

udpate: /boot/grub/menu.1st had a new stanza added with the "xen" kernel suffix. Also changed default to 0 in this file.

rebooted and i am at least able to run virt-install.
