NET: Registered protocol family 2
The above is the last thing that I ever saw, I tried pci=routeirq etc.. and it wouldn't work.
Just enable "IOAPIC" in the settings for your Centos Guest and you'll find the kernel boots just fine. I wonder if a physical system might stall in this same way if the BIOS has IOAPIC disabled which many people do as a troubleshooting method.
