Simple setup, two host cluster ESXi 6.5. I have 15-20 VMs on host A that I want to vmotion to host B in prep for ESXi patching.
I would say 10 of the VMs vmotion just fine. The other 4 or 5 appeared to vmotion (no errors were generated or anything, shows as 100% completed) but afterward they remained on host A. !
In the web client I right-clicked the header row and added the column 'host' on the VM inventory, sure enough a handful of VMs still remain on host A.
Double-checked for some potential causes, there are no snapshots on these VMs and no ISO mappings.
Went back in and attempted to vmotion one of these stragglers for a second time, now host B is not even showing up in the dialog as an option to migrate to, it only shows 'host A' which is not helpful as it's the host it's already on.
I vmotion it to host A now just for grins. Completes successfully in a millisecond. Stuck in a loop with this... any ideas?
