I recently had this problem, but forgot to take a screenshot for the blog, sorry guys.

I was patching an HA/DRS cluster using VUM and none of the VMs would migrate off one specific host. The error it gave was “A general system error occured: Failed to start migration pre-copy Error 0xbad010d. The Esx host failed connect over the VMotion network”.

Immediately I enabled SSH on the troubled host and used vmkping to ping every vmotion interface/ip of all nodes of the cluster. As I was doing this, vmotions started working fine.

I googled it and found this article: http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1013150

Problem is it states it’s fixed in 4.0 Update 2, yet my host is 4.1.

In short, here’s what I did:

and then

and pinged every vmotion IP address for EVERY node in the cluster, including it’s own IP address.

Hope that helps someone!
