[Libvir] PATCH: Fix KVM / QEMU pxe boot config

The XML config for PXE boot is being parsed/formatted incorrectly by the KVM tools. It is using 'net' instead of 'network' for the <boot> tag. I had even made this mistake in the test suite :-) Patch is simple - also fixed a flaw in the test suite code Dan. -- |=- Red Hat, Engineering, Emerging Technologies, Boston. +1 978 392 2496 -=| |=- Perl modules: http://search.cpan.org/~danberr/ -=| |=- Projects: http://freshmeat.net/~danielpb/ -=| |=- GnuPG: 7D3B9505 F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 -=|
