Hey guys, One of our VMware hosts has stopped passing any traffic via a vswitch. We migrated all VMs off this vswitch, to another physical NIC and different vswitch. The failing vswitch has been deleted, the physical switch port configuration has been checked, it has the correct VLANs configured. A new vswitch has been created, but alas still the same fault. I am thinking hardware failure of the NIC (this is the second port of the onboard nic), switch port failure (will have to get somone onsite to check the vlans are working ok) or my ESX host needs a reboot... Has anyone come across something like this before? We are using ESX 3.5, with no HA/DRS. Just a single host with direct attached storage.
