Networking Issues

[bwiechman]

I recently installed ESX 3.5 and was working with a pair of VMs - one Centos 5, one win2k3.

Both were assigned to the same virtual network with one interface. I originally assigned an IP to the win2k3 VM, but needed to migrate this IP to the Centos VM so I shut down the win2k3 guest OS, and the VM was stopped at this point. However I was unable to assign that IP to my Centos machine because it was determining that particular IP was in use on the network.

I started the win2k3 VM again and assigned it a different IP and left it running.

I was still unable to assign the IP to the Centos machine. Eventually I actually removed the NIC from the win2k3 VM, at which point I could assign the IP address to the Centos.

Was the virtual switch both these guests were attached to responding the the arping request from the Centos machine for some reason?

Hello,

I think you should report this to VMware via your Support Specialist. They will want to fix this, or verify how it can be caused. I have never heard of something like this on a vSwitch.
