CentOS 5.5 VMをkvmからbhyveに移行して動いた。

loader="grub"
cpu=1
memory=2G
network0_type="virtio-net"
network0_switch="public"
disk0_type="virtio-blk"
disk0_name="disk0.img"
grub_install0="linux /isolinux/vmlinuz acpi=off"
grub_install1="initrd /isolinux/initrd.img"
grub_run0="linux /vmlinuz-2.6.18-194.26.1.el5 ro root=/dev/VolGroup00/LogVol00 acpi=off"
grub_run1="initrd /initrd-2.6.18-194.26.1.el5.img"

grub_run は /boot/grub/grub.conf あたりで確認。カーネル更新時に要変更？

時刻がずれる問題がある？
