Hello All,

I have been building a new server to deploy using Xen. However, seeing that Redhat is moving towards KVM, it would seem beneficial to deply this server using KVM as well. This is a Centos 5.4 x86_64 fresh install.

So here is the scoop:

 * running the xen kernel with 2 vms works great. I have 2 vms- a cobbler
   host and an ldap host.
 * running with non-xen kernel, I can't seem to get anything to work
   right. Using virt-install from the command line, I get the response of
   "Host does not support any virtualization options" yet I know it does.

What am I missing here?

I spent some hours last night searching and came up empty.

What does "xm info" say about caps/capabilities? Do you see hvm supported?

Xen HVM guests require CPU virtualization extensions (Intel VT, AMD-V) to be present and enabled in the BIOS.
