[Libvir] [PATCH 6/6] Inactive domain support: xm config backend

This is the main patch. It adds a new 'xm config file' backend driver to libvirt. This basically just scans /etc/xen for config files, reads them and turns them into libvirt XML to create domains. Similarly it can accept libvirt XML and create config files from it. Some important points - It can override /etc/xen with LIBVIRT_XM_CONFIG_DIR env variable - It only re-scans /etc/xen every X seconds & caches parsed config files in-memory to avoid parsing / I/O overhead - Automatically generates a UUID if the config file doesn;t have one - Skips over a blacklist of files from /etc/xen which are known to not be valid config files to avoid too many error messages - Filters list of inactive domains to strip out any which are currently running (acccording to XenD) - Allows changing of VCPUS, memory & max memory config settings and writes changes back out to disk - Can start, create, delete domains from disk Regards, 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 -=|
