Comment 11 for bug 682831

OK. so I realize how I incorrectly read the comments in drivers/xen/console/console.c. I had assumed that you should pass 'xencons=hvc' and it would allocate one hvcX device. Instead, I tried:

xencons=hvc0 console=hvc0 and I see:
[ 0.000000] Kernel command line: root=LABEL=uec-rootfs ro xencons=hvc0 console=hvc0
[ 0.000000] console [hvc0] enabled
[ 0.836722] Xen virtual console successfully installed as hvc0

and, I get all the data.

So, I see 2 solutions to this:
a.) change update-grub-legacy-ec2 to add 'xencons=hvc0 console=hvc0' (it already does console=hvc0).
b.) change the kernel default to be hvc0. I haven't verified it, but just from the data above, it would appear that it is defaulting to 'tty1'.
