  Looks like there might be an error with the IPv4 config of the igb0 
interface - those addresses appear to be invalid. Though, that shouldn't 
really matter for a bridged config.

  That looks Ok.

  Can you try a 'lspci -vv' at the Linux shell prompt ? That will show 
if the virtio-net PCI device was at least probed.

  When you did the initial install, was any networking configured ?

later,
