A customer wanted CentOS, so I tried doing it like I did my Ubuntu
install --- no luck with the grub loading up automatically.
Here is basically what I did ... it works, but I get all these odd
characters in my terminal (if I hit tab, I can guess at the menu items
and successfully make it through the installation process). I need to
clean up this how-to, but here it is...
START INSTALL -----------------------------------------
# cd /data/images/
# truncate -s 200G vm2.img
# cat vm2-device.map
(hd0) /data/images/vm2.img
(cd0) /data/distributions/CentOS-6.5-x86_64-minimal.iso
# bhyvectl --vm=vm2 --destroy
# grub-bhyve -r cd0 -m /data/images/vm2-device.map -M 2048 vm2
grub> linux /isolinux/vmlinuz
grub> initrd /isolinux/initrd.img
grub> boot
# bhyve -c 2 -m 2048M -H -P -A \
-l com1,stdio \
-s 0:0,hostbridge \
-s 1:0,lpc -s 2:0,virtio-net,tap1 \
-s 3,ahci-cd,/data/distributions/CentOS-6.5-x86_64-minimal.iso \
-s 4,virtio-blk,/data/images/vm2.img vm2
END INSTALL -----------------------------------------
Is there something like this that will clean up the output from the
CentOS install program?
grub> GRUB_TERMINAL=console
The boot part is messy (how to I load up the grub.conf from inside the
install image?
START BOOT -----------------------------------------
# grub-bhyve -r hd0,msdos1 -m vm2.map -M 2048 vm2
grub> cat /grub/
Possible files are:
grub.conf splash.xpm.gz menu.lst device.map stage1 stage2

grub> cat /grub/grub.conf

Also, this is making me wonder... am I doing this wrong? I am using
install CD images, are other people using pre-made CentOS images?
I have noticed grub-bhyve requires a space at the end of the line or I
get 'OM' on STDOUT and the line fails. Above, I hit the up-arrow then a
space (
