Try chyves and use UEFI booting. I think you might have hit a grub limit.

For chyves, it is a fork of iohyve so it will be familiar for you. Follow
the documentation for a Windows UEFI install.  You need the UEFI blobs as
well and import them into chyves, see bhyve-firmware in packages. Make sure
you adjust the zvol block size in the default config before creating your
guest or you will wonder where your storage starts to disappear to.

Cheers,

Dear all,

Is there a limit with respect to the size of the virtual drive I can create
for a VM using bhyve? Presumably not but I’m running into problems with a
larger drive.

I am trying to create a 4T Ubuntu machine on a FreeBSD11.1 server using
iohyve. There’s plenty of drive space available so it’s not a drive space
issue. I am able to create a 40G machine without any problems but exactly
the same commands to create a 4000G machine results in a server that won’t
boot past Grub. Is this an iohyve issue perhaps?

Commands used that results in a working Ubuntu server:

iohyve create ubu 40G
iohyve set ubu loader=grub-bhyve os=debian ram=40G cpu=10
iohyve install ubu ubuntu-16.04.3-server-amd64.iso <
ftp://ftp.cuhk.edu.hk/pub/Linux/ubuntu-releases/16.04.3/
ubuntu-16.04.3-server-amd64.iso>

Commands used that results in a broken Ubuntu server:

iohyve create ubu 4000G
iohyve set ubu loader=grub-bhyve os=debian ram=40G cpu=10
iohyve install ubu ubuntu-16.04.3-server-amd64.iso <
ftp://ftp.cuhk.edu.hk/pub/Linux/ubuntu-releases/16.04.3/
ubuntu-16.04.3-server-amd64.iso>

The screen I get in the console when I boot (iohyve start ubu) the 4T
machine is:

                             GNU GRUB  version 2.00

   Minimal BASH-like line editing is supported. For the first word, TAB
   lists possible command completions. Anywhere else TAB lists possible
   device or file completions.


grub>

Does anyone have any ideas? I’ve been at this for hours trying different
configurations. LVM is not selected when installing either of the above
machines as that seems to cause more problems.

Many thanks,
Dylan.
