This causes a good speed up with regards to moving machines around.

This was our dev environment anyway, so it was less of an issue. With a quick bit of work, we moved some guests around, and bumped into the same 32% issue again. So the solution was to disable VAAI on the host, do the vMotion, and then re-enable it if you still want to use it. Vmotion Fails At 20 At this point, we now had a third SAN added to the mix, so we presented new data stores, and went through the process of trying to vMotion quite a lot

At this point VMware decides the migration has timed out, and rolls back. Now test the SVMOTION which will complete without any issues .

Okay, the details don’t exactly match, for example the document mentions that it freezes at 10%, but it had all the hallmarks of what we were seeing. It had to be a fiber or switch issue… Right?
