I ran into some of the issues a few times. I am not saying this will fix it if your using the vms to test really it isn't an issue yet. On the 18.04 base stuff try upping the ram to 2GB in the machine and also try redoing the machine with more space like 20GB. I had some of the lockups with my testing on my stuff with not using enough ram and/or giving it enough space. The new way of using a swap file is the issue and not having enough ram will make it expand the swap to compensate for that. Just from my testing I can concur that the 4.15 kernel is leaving older hardware behind but I am still getting support for 10 year old stuff so far. You should try both solutions separate to see if one fixes it.
