I've been trying to get vMotion working on vCenter 4.0.U1 / ESX 4.0.U1 to no Avail.
I've followed the Guide for manual installation (we use dvSwitches) and all traffic flows correctrly through the Protected/unProtected dvPortGroups/switches.
I enabled the vpxd.cfg settings mentioned in the kb1006701
[http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1006701])
but it doesn't help at all.
I've noticed on the kb (updated Jan 06 2010) that vSphere 4 / ESX 4 / vCenter 4 isn't mentioned. Does that mean that vSphere 4 won't work with vShield Zones and vMotion
