One of the criteria for vMotion is that "VM and Both ESX hosts must be in same “VMNetwork” port group".  What does the port group mean ? Can I say there are  5 VM port groups in the attachment ?

Thx

"My VM network" is a port group. You want to have the two host on that same network or port group for vmotion to work and communicate between the two host.

Basically it  means that the VMKernel Portgroup for vMotion must be in the same Subnet Network for communications.

e.g. 192.168.0.1 and 192.168.0.2, so both vMotion VMKernel Portgroups on the Servers can communicate.

In your attachment you have 3 VMKernel Portgroups, and 2 Virtual Machine Portgroups, to be honest with you, it's a bit of a mess!

Management Network - vmk0 -  192.168.30.130
Management - vmk1 - 192.168.30.138
VMKernel 3 - vmk3 - 192.168.30.136

Now the question is why the other two ?

Do you need to have two management IP Addresses 192.168.30.130 and 30.138 ?

also it's best to have vMotion on a completely different subnet e.g. 10.10.x.x or 172.16

Talk to me, and we can recommend, what is best.....and get this correct!

If your Networking is rubbish in VMware vSphere, so is VMware vSphere, VMware vSphere is only as good as your networking!
