In general, we have anywhere from 6-8 active SVN requests, so having more CPU would probably not hurt, but I don't understand how CPUs work in this environment; I assume that we don't have to match the total 'CPUs used' on the system to the number of actual cores, and can exceed that. If someone can confirm that, I'd bump that number of virtual CPUs to 4 instead of 2.

If not, then I hope Alex (or someone else?) can work with OSUOSL to set up the new VM tomorrow, so that work can begin on the transition this weekend.

As some may have heard, this VM is up and ready. Are we on for migrating
Trac/SVN this weekend. Some users in the community have asked that we
send out a notice of potential downtime, or the time window in which
commits may be lost and should not be attempted.

Thanks,
