Do you have a full duplicate of your /usr/lib/python2.7 inside
/lxc/rootfs? It looks like the connect call is trying to import
something, and now that you're chrooted, it can't find it. The
solution might be to manually import a few more modules beforehand
(putting them into sys.modules means they don't need to come from the
file system), or to add more files to your chroot jail.

For a guess, I would try:

import MySQLdb.connections

above your chroot, and see if that helps.
