To speed up the booting of a bhyve VM I'm using this method :
nohup /usr/sbin/bhyve -S -c sockets=3D2,cores=3D2,threads=3D2 -m 8G -w -H -=
A \
-s 0,hostbridge \
-s
1,virtio-blk,/mnt/zroot2/zroot2/bhyve/img/Linux/Ubuntu2310.img,bootindex=3D=
1
\
-s 11,hda,play=3D/dev/dsp,rec=3D/dev/dsp \
-s 13,virtio-net,tap19 \
-s 14,virtio-9p,sharename=3D/ \
-s 30,xhci,tablet \
-s 31,lpc \
-l bootrom,/usr/local/share/uefi-firmware/BHYVE_UEFI_CODE.fd \
vm0:19</dev/null >/dev/null 2>&1 &
if test -f nohup.out; then rm -r nohup.out
fi
I've installed a ssh server within the vm and I connect to it from FreeBSD
using ssh -Y user@IP ; it's faster. But the project is not completed. I
want to install VirGL to have the graphic acceleration without using the
real GPU of the host inside the VM.

I'm in repeatable build land, working in Linux and developing a FreeBSD=

Which in turn means that every setup step for a FreeBSD image comes with <b=

a pretty high coding and maintenance cost.<br>
<br>
So my question is:<br>
What's the FreeBSD image that has the least number of steps to get the =
<br>
base system up and running? I suppose it's the VM-IMAGES section, but i=
s <br>
this correct?<br>
<br>
Follow-up question:<br>
The startup time needs to be as fast as possible. Sub-second would be <br>
great ("don't disrupt the developer's thought stream").<b=

I see the boot process from a vanilla VM-IMAGES image takes multiple <br>
seconds; can this be sped up to just a few seconds, or do I need to run <br=
