I had a discussion with some of the devs on IRC in which they said that while linux-vserver has no architecture-dependent code, and so far it's been proven to be platform-agnostic, it hasn't been tested on this platform. They did make it quite clear, however, that they would work to resolve any glitches the platform change might cause. As you say though, it could be a problem. If there's no way of getting an actual copy of the VM OS, though, I think it's probably the best alternative. > > > Some questions: > 1. How many users do you anticipate? I know that I expect to run, at most, about 20 VM's. That number may rise in the coming years, but I doubt it will ever get above 50. The users on those VM's will probably be about 30 to start out, and I doubt the total will pass 100 in the coming years. 2. How many simultaneous users? That will vary quite a bit, but I'm going to guess the peak with the 30 starting users will probably be around 20. 3.
