illumos gate

For testing on OmniOS using virtualbox and vagrant from the OmniOS extra repository.

As root (skip the first line if the extra.omnios publisher is already configured, although it won't do any harm to re-assert it)

pkg set-publisher -O https://pkg.omnios.org/r151034/extra extra.omnios
pkg install vagrant virtualbox

As non-root:

mkdir bento
cd bento
vagrant init bento/debian-10.4
vagrant up

Expect this to fail on an AMD box (or on Intel when bhyve or KVM is already running).

Now, as root:

echo set hma_disable = 1 > /etc/system.d/hma
init 6

and try again (as non-root):

cd bento
vagrant up
vagrant ssh
vagrant destroy

Kindly tested for me by Volker A. Brandt on an AMD machine:

"Six-Core AMD Opteron(tm) Processor 8431"

Using OmniOS r151034 with Virtualbox 6.1.12

[20:15:19]  <v_a_b> OK, now everything works as expected.  Summary:  Without hma_disable=1, the VBoxHeadless will dump core.  With hma_disable, the vagrant debian box will come up and work fine:
[20:15:22]  <v_a_b> vagrant@debian-10:~$ uname  -a
[20:15:22]  <v_a_b> Linux debian-10 4.19.0-9-amd64 #1 SMP Debian 4.19.118-2+deb10u1 (2020-06-07) x86_64 GNU/Linux
[20:15:22]  <v_a_b> vagrant@debian-10:~$ uptime
[20:15:22]  <v_a_b>  19:15:04 up 4 min,  1 user,  load average: 0.00, 0.02, 0.00
[20:27:01]  <v_a_b> For giggles, I also tested oracle-8.2 and freebsd-12.1 -- both work fine.
[20:29:44]  <v_a_b> I now have three "VBoxHeadless" procs running, everything is stable.
