[libvirt] PATCH 0/0: Support setting a disk drive serial (number) v2
This is a second version of the patch posted here
http://www.redhat.com/archives/libvir-list/2009-August/msg00341.html
In this version, I make the QEMU driver refuse to run with any serial
that doesn't contain 0-9, a-Z, -, _, since there's no way to escape
special chars in QEMU command line args. Hopefully we can lift this
restriction in a future version of QEMU
I also add a check that serial=s is actually supported by QEMU
