Currently the way to do so is to send a patch to modify $MaxActiveVMs, 
and/or $MaxRevertsWhileRunningVMs in testbot/lib/WineTestBot/Config.pm 
to Alexandre.

However the old VM host had an 8 core CPU and the limits are to run at 
most 2 VMs at once, and each VM has only 2 cores (except the build VM 
which had 4). So really there should not have been much contention on 
the cores (which it seems like should be all that matters for these 
tests).

The new VM host has only 4 cores (+hyperthreading). We're still only 
running two VMs at a time but now the build VM only has 2 cores.

We can do a test with $MaxActiveVMs = 1 and $MaxRevertsWhileRunningVMs = 
0 but that would really limit performance.
