VPXD.EXE at 100%
After a relaxing 20 days vacation I’m back.
And right on my first day back a weird issue had pop up.
Virtual Center could not be opened, the O.S. was very unresponsible, when checking the processor utilization it was at 100% all the time and the most offender process was vpxd.exe
Getting a little of background of what have happened during my absence I realized the VC has been moved from one cluster to a new one. (it was supposed to happen since we are migrating our environment).
I started wondering if the issues could be because of that change and then I decided to revert it.
After shutdown the VC and register it back to it’s previous host/cluster the O.S just started normally, Virtual Center was working fine again.
But several v-motions tasks (started by DRS) started.
I wait all v-motion tasks to finish and the work load to establish on the new cluster.
At this point I can only guess
When VC started on the new cluster and tried to load balance it’s load through DRS it got kind of crazy with the situation of a new guest has been added to the cluster while it’s off, not just any guest, in fact the problem was because it’s new guest is the virtual center itself, so it went in a kind of loop.
That’s what I did to successfully migrate the VC to the target cluster.
I disabled DRS for the new cluster.
Shutdown VC again
Register it on the new host/cluster
Start the VC again
This time the VC has started properly and I just needed to enable DRS back.
Lesson learned:
When moving your VC to another cluster, first disabled DRS on the target cluster and re-enable it back after the migration.
See you.

Good one indeed. I believe we just had one episode like this one this week where we had to reset the username and password in the vCenter registry and force it with the vpxd. Exercise - p switch
