vSphere - automatic migrating and errors
I have a mini environment with two hosts esxi 5.5, vCenter 6.0.
for some reason I keep seeing in the status pane an error:
View details:
I am not attempting to migrate any VM. Is it doing that automatically somewhere? Anyway to turn off?
Also, I can manually migrate a VM if I choose the right network, so I'm not sure why this error would be generated.
Where should I check on that?
It's just two hosts

vMotion uses VMKernel Portgroups.
I would check your network, and VMKernel Portgroups which are selected for use with vMotion.
This can be done using VMKPING.
OR, upload screenshots of your networking here.

Hi,
as mentioned, check if you have only one or several vmkernel configured for use with VMotion on each host.
You should have only one vmkernel per host with box "use for VMotion traffic" checked, in your vswitch properties and then vmkernel properties.

The VM's appear to be on the VM Network of the standard switch on the host, not on the Distributed Switch.
The host is trying to use a vMotion Portgroup, which does not communicate with the destination server's vMotion portgroup.
again, troubleshooting, if you cannot easily see the issue, is to use VMKPING and send packets through each VMKernel portgroup.

do you require any additional help to close this questiom?

I've turned DRS off, that fixed the errors.
Now, I can vmotion the VM's between hosts. So I'm not sure why automatic is not working.
Is DRS supposed to use a specific port group for that?
