CentOS is grub v1 which isn't quite compatible with grub2 (e.g. linux
-> kernel).
grub-bhyve can pick up a config file from the host system: use "-r
host" to force that, and the -d option to change the default path for
grub.conf. No need to redirect input.
Then, in grub.conf on the host, put in the absolute path with the grub
commands e.g.
kernel (hd0,msdos1)/vmlinuz-2.6.32-431.el6.x86_64 ro
root=/dev/mapper/VolGroup-lv_root rd_NO_LUKS LANG=en_US.UTF-8 rd_NO_MD
KEYTABLE=us rd_LVM_LV=VolGroup/lv_swap SYSFONT=latarcyrheb-sun16
crashkernel=auto rd_LVM_LV=VolGroup/lv_root rd_NO_DM
initrd (hd0,msdos1)/initramfs-2.6.32-431.el6.x86_64.img
boot
(the console=ttyS0 isn't needed: grub-bhyve auto-inserts that).
later,
Peter.
