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):

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

Any idea on how to fix this?

Thanks!

Ok, the kernel was the problem.
It was a custom kernel installed by the hosting provider.
So I apt-get install'ed the distros kernel; upgraded grub; rebooted; and done!
