[one-users] adding Xen host to KVM cloud

[Steven Timm]

DOCS say I should be able to do

REQUIREMENTS = "HYPERVISOR=\"xen\""

I have done this in my template,

[timm at fcl002 ~/OpenNebula]$ onevm show 177

but VM stays pending forever.

As you see I do have one hypervisor=xen node as shown in
the onehost show virtual machine.

What's happening?
