Serial console and kernel parameters (to fix console hanging)

I had to do the following on my image to get the serial console to work:
echo "hvc0:2345:respawn:/sbin/agetty -L 9600 hvc0" >> /mnt/etc/inittab
echo hvc0 >> /mnt/etc/securetty

I also needed to add "console=hvc0 xencons=tty" to my list of kernel parameters:
kernel /boot/vmlinuz root=/dev/xvda1 console=hvc0 xencons=tty

PVH mode

Since the kernel is now new enough it would be good to have Gentoo guests run in PVH mode. All that needs to be done is:

  • enable PCI, XEN_PVHVM and ACPI
  • enable CONFIG_XEN_PVH in the kernel (as well as CONFIG_XEN_PV for now)
  • install that kernel
  • shut down
  • xen shell> virtmode pvh
  • xen shell> boot

No reason why it shouldn't Just Work but if it doesn't, switch back to PV mode.

Could a Gentoo user please give this a try and update the article?
