* Got the server start function to the point where all data that we need to sanity check is gathered. It already verifies that the emulator exists, that there is enough RAM and that the server's name matches the name we expect.
# 1. Read the XML definition file and find the backing storage and bridges. Soft error if read fails.
# 2. Make sure the name matches.
# 3. Make sure we have enough free RAM.
# 4. Make sure the emulator exists (can be an issue after migrating from an different gen Anvil!).
# 5.1. Make sure optical drives with mounted data have the disk present. Soft error if not.
# 5.2. Find any backing DRBD devices
# 6. For each DRBD device;
# 6.1. Make sure the backing LV is ACTIVE. Soft error if not.
# 6.2. Check if the drbd resource is up. If not, up it.
# 6.3. Make sure the backing disk is UpToDate. Soft error if not.
# 6.4. Make sure the backing device is 'Connected' or 'Connecting'. Call a connect if not.
# 7. Make sure all bridges exist and soft error if not.
# 8. Start the server.
