Console of P2V?

Hey, all. For one, apologies if this isn't quite the right list, I tried to get the right one. But, my problem: I'm firing up a Centos 6.5 box with virt-install, recently converted from a physical (I did a 'dd' to a raw image, and converted it to qcow2), and it boots fine, etc., etc., but I can't get to the console except through vnc; "virsh console" just shows a blank screen. Do I need to tell the kernel to boot in ASCII mode or somesuch? Thanks! -Ken
