part of the kernel panic

Yesterday I tried to install Gentoo in a KVM VM, using livedvd-amd64-multilib-20121221.iso. This didn't work, because of a kernel panic very early during boot.

This seems to be a known issue, caused by running kvm with "-host cpu", and not having KVM guest options enabled in the kernel config. Booting the same ISO with "-host kvm64" works just fine.

This seems to be a known issue, see https://bugs.launchpad.net/qemu/+bug/1037675 for example. The solution to be able to boot with "-cpu host", is to enable these kernel options, so please enable these in the next livedvd iso:

CONFIG_KVM_CLOCK=y
CONFIG_KVM_GUEST=y
CONFIG_PARAVIRT=y
CONFIG_PARAVIRT_CLOCK=y
