I don't think it's entirely surprising given the long revert times we're seeing.
On the contrary I find that surprising.
My understanding is that the MSI tests are I/O bound. But given the long revert times, reverts are not doing much I/O at all so they should not interfere that much with the tests.
However based on some times I looked at this recently the QEmu process spins its heels, seemingly doign nothing. That means it keeps a core fully occupied. But given that the VM hosts have at least 4 cores each that should still not slow down the MSI tests much given that they only have access to two cores anyway.
It seems to me that adding more hardware (to have fewer VMs per host) is the pragmatic way forward.
It would also help to have more people contributing to the TestBot.
