Default Virtualization With KVM On Ubuntu 11.10

Hi folks, I'm having a problem with this how to;
after I run the vmbuilder command; it dies with:

W: Failure trying to run: chroot /tmp/tmpgV5qi2 mount -t proc proc /proc
, stderr:

Looking at the info the error comes from:

W: Failure trying to run: chroot /tmp/tmpgV5qi2 mount -t proc proc /proc
, stderr:
Traceback (most recent call last):
File "/usr/bin/vmbuilder", line 24, in <module>

raise VMBuilderException, "Process (%s) returned %d. stdout: %s, stderr: %s" % (args.__repr__(), status, mystdout.buf, mystderr.buf)
VMBuilder.exception.VMBuilderException: Process (['/usr/sbin/debootstrap', '--arch=amd64', 'natty', '/tmp/tmpgV5qi2', '']) returned 1. stdout: I: Retrieving Release

Digging up a bit looks like that it can't mount the proc inside the chrooted environment.

Any idea on how to fix this?
