Why do some of my Virtual Machines lose their network connection when they are power cycled?
Posted on 2008-06-23
I have a VMware ESX Server (3.0.2) single host environment and am having some issues with my VM network connectivity. I have a few real (as in, not Virtual) NIC bonded networks set up and for some strange reason, when I power cycle some of my VMs, they lose their network connectivity.
This is indicated in VirtualCenter by showing an IP address of 0.0.0.0. If I go into the configuration for the VM, it shows the "Connected" box for the NIC as unchecked. The fix for this is to check the "Connected" box, switch the network the VM is on to another one temporarily, apply the configuration, and then switch it back to its proper network. The connection to the VM then returns. I have seen this behavior since installing 3.0.2 and never saw this in 2.5.4.
Any idea what's happening here?
