Do you happen to have a ZFS partition?
I think some changes to some of the bootstrap (pre-loader) code that is
shared with bhyve-load, means it always prefers ZFS over UFS (normally
for booting a real machine, you use a different bootstrap for UFS than
for ZFS, but bhyve-load is a special case.

e the compression setting.
If you want to recompress the entire volume:
1) stop the bhyve
2) snapshot the volume
3) create a new volume, with compression enabled
4) zfs send -e oldvolume@snapshot | zfs recv -F newvolume
5) start the bhyve using the new volume
6) (optional) destroy t
mands, and you will see
the space become free in your zvol.

I would expect the answer is `poudriere image` with a src.conf with many
WITHOUT_* knobs to disable things you don't need to get the image down
in size. There is likely a list of such knobs you could borrow from nanobsd.

There isn't really any difference between a zvol and a thin-provisioned
zvol, unless you run out of space (if you over-provision).

Also consider that 'zfs' commands show size after its calculations of
what the expected raid-z parity space consumption will be, but does not

'Wired' memory, specifically means that it cannot be paged out. It is
not bhyve, it is ZFS.
Please lower your vfs.zfs.arc_max to about 10-12 GB instead of 60+ GB it
is at now.
And you might also want to double your: vfs.zfs.arc_free_target to make
ZFS give up memory more easily.

You might also find the sysctl:

If you read the handbook, it first does an 'ls' on the cd. You have to
load files that actually exist, they might have slightly different names.
The instructions in the handbook were based on how the files were named
on a CentOS 6.5 cd, 6.6 might be slightly different.

This section of the handbook describes the steps required to upgrade
your system to FreeBSD 11-CURRENT:

ol, and does not have the volmode set, and GEOM on
the host is grabbing the disk and locking it, preventing writes
2) The VM was shutdown ungracefully and the file system needs a fsck.
Since you can get into single user mode, this should be doable.

solve this issue, but have not yet. If you system has enough cores to
support using more than 16 per VM, you can modify the file and recompile
the kernel and use as many CPUs as you want, but not much testing has
happened with bigger numbers.

bably not work on 10.1. Since you are compiling a custom kernel, you
should probably build VirtualBox from source to get an exactly matched
kernel module, and see if that solves your issues.

Is the disk for this VM a ZFS zvol?
You might need to set the 'vol mode' to make GEOM not steal the disk.

After the first run, before the second, did you bhyvectl --destroy --vm=blah
and then do the grub-bhyve step again (off the disk instead of the
install image this time)

ere is probably disk performance. If you do
something that is pure CPU, you'll usually get about the same
performance as the host, but virtualized disk is not always nearly as good.

That definitely won't work, bhyveload is very specific to freebsd. A
generic boot system would use some other command, or none at all.

The tap device can also be created automatically by bhyve, make sure you
specify a different tap device for each instance of bhyve.

Just like when the same thing happens on FreeBSD, the issue is that the
console output is not being directed to the serial port.
You must configure the OS as if it was running on a machine with no
video card, only a serial port.

What version of FreeBSD are you using? You might want to try the latest
10.1 RC (or HEAD if you are so included) instead, as they have much
improved bhyve.

would that remove the requirement for UG to boot Linux, if it was booted
