I'm trying to run Xen on Ubuntu Server 11.10. I tried following the wiki, but it's a bit obsolete, so I tried following a blog post. Everything seemed to be going well, until I ran
virsh version, which shows:
Compiled against library: libvir 0.9.2 Using library: libvir 0.9.2 Using API: Xen 3.0.1 Cannot extract running Xen hypervisor version
Oddly, when I booted, I manually selected the Xen kernel...but then a second Grub menu appeared, requiring I select a "normal" Ubuntu kernel.
Also, when I ran
grep vmx /proc/cpuinfo, it showed my CPU (an Intel Xeon E3-1230) had VT support. But now when I run it, it doesn't show anything, which is weird because Intel's docs explicitly say it has VT support.
How do I determine what went wrong and fix it? Is there an official guide on installing Xen on Ubuntu 11.10?
