The guest is still connected to the VSWITCH and the virtual NIC has been initialized, but ithe guest is not transmitting anything on the interface. The lack of any TX packets indicates that the guest doesn't know what IP address to assign. On an ETHERNET mode vNIC, we would see gratuitous ARP packets on an "ifup". Do you get errors when you manually bring the interface up?
As an aside, I observe that you have the VSWITCH defined "VLAN 1 NATIVE 1". I have said repeatedly, here and elsewhere, use NATIVE NONE. Anyone who thinks they need to transmit untagged frames on a trunk port should discuss that with their switch admins -- you are putting your physical switch at risk. I suspect you're not plugged into a trunk port, and by coding VLAN 1 NATIVE 1, you are forcing all NICs on VLAN 1 to be transmitted without tags. That works because the switch port is actually an access port.
