So, systemd-machined has this philosophy that machine names are like hostnames and hence should follow the same rules. But we always allowed international characters in domain names. Thus we need to modify the machine name we are passing to systemd. In order to change some machinenames that we will be passing to systemd, we also need to call TerminateMachine at the end of a lifetime of a domain. Even for domains that were started with older libvirt. That can be achieved thanks to virSystemdGetMachineNameByPID(). And because we can change machine names, we can get rid of the inconsistent and pointless escaping of domain names when creating machine names. So this patch modifies the naming in the following way. It creates the name as <drivername>-<id>-<name> where invalid hostname characters are stripped out of the name and if the resulting name is longer, it truncates it to 64 characters. That way we can start domains we couldn't start before. Well, at least on systemd. To make it work all together, the machineName (which is needed only for systemd) is saved in domain's private data. That way the generation is moved to the driver and we don't need to pass various unnecessary arguments to cgroup functions.
