Public bug reported:

Impact: this appears to stop vmbuilder from creating a Quantal VM completely.

Evidently the kernel package now looks for /proc/cpuinfo in order to check for PAE support (since PAE support is going away in Quantal). I think this is failing because /proc doesn't exist in the environment that vmbuilder is using.

Tested on a fresh Quantal cloud image, dist-upgraded and python-vm- builder installed from the current Quantal archive. The only catch here is that I did it on a virtual image, but I can't see how that would affect this.

Possible solution: mount /proc inside the chroot?
