vmotion won't work when when vm machine is runing

[michelvaillanco]

Hi,

I am trying to test my VMotion in a lab environment but it doesnt seem to work when the VM machine is runing.

when I shutdown the VM and try to migrant it manually then every thing seems to work just fine. but when the VM is runing and I try the same thing as before then the migration start and after 14% get stack and a general error appear." The vMotion migrations failed because the ESX hosts were not able to connect over the vMotion network. Check the vMotion network settings and physical network configuration"

I need Help,

The error message actually points to the issue. please provide some details about the ESXi hosts' virtual network setup. Basically the vMotion VMkernel ports should be configured with IP addresses in a dedicated subnet (e.g. 192.168.x.x/24) and must not be routed.

Please check below article:

could it be because I am using an nfs storage? that is why the vmotion wont work?

No, vMotion is supported on NFS data stores if it is shared.

Can you try to ping your ESX vMotion network by using "vmkping <ip of vmotion network>" from the ESX host and see if it is pinging.

Thanks,

Please provide brief overview of your ESXi host' virtual network settings, and the physical switch you are using?

In this case there is some problem over your physical network because it could not ping. You need to make sure that both the vMotion nics have connectivity with each other. Also make sure that you have configured vMotion switch properly.
