We have been experiencing some VM's losing network connectivity sporadically. The VM's stay online for a while then suddenly it acts like it is no longer on the network. Everything appears to be correct. The vNICs are connected and you can get to the console. I can't ping it from outside the host and the VM can't ping it's Def Gateway.
Hardware is 4 HP Gen 8 LFF with Quad port NIC's HP NC364T running ESXi 5 U1 with vCenter Server clustered.
Anyone experience this?
If I vmotion it to another host it comes back online. That's been our temporary solution.
Thanks
