bhyve/iohyve 2GB RAM limit?

[RoboKaren]

I'm running Ubuntu in a bhyve but I can't seem to set the RAM to more than 2GB and have it reflected in the VM :

Code:

[me@bethel] ~% sudo iohyve getall ubucrashplan
Getting ubucrashplan iohyve properties...
bargs		  -A_-H_-P
boot		   0
con			nmdm2
cpu			2

install		no
loader		 grub-bhyve
name		   ubucrashplan
os			 debian
persist		1
ram			6GB
size		   50G
tap			tap4

and yet in my virtual machine

Code:

me@ubud:~$ sudo lshw

Did you use a 32-bit Ubuntu ISO?

 

[RoboKaren]

Nope, I had thought of that. I had also thought of using 4096, 4096M or 4096MB as alternates to 4G or 4GB or 6G in the RAM settings of iohyve (which doesn't seem to do any sanity checking).

Code:

uname -a

Linux ubud 4.8.0-27-generic #29-Ubuntu SMP Thu Oct 20 21:03:13 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

 

[Sakuru]

1. Which version of FreeNAS are you running?
2. How did you create the VM?
3. Did you change the amount of RAM after creating it?

 

[RoboKaren]

1. U4
2. Using iohyve
3. I had initially set it as 2G then tried to expand it to 4G. Is this not something that's doable?

Something happened in upgrading to 9.10.2. My iohyve VM wouldn't startup with UEFI so I switched to grub-bhyve.

When the VM started back up, it was running with the increased RAM.

I'm not sure if it was something in 9.10.2 that fixed it, or if it was a the UEFI loader switch to GRUB that did it, but in either case I now mysteriously have my missing RAM.
