Hello.
I would like to inform you about a bug that afflicts bhyve that doesn't let
me run more than one virtual machine at the same time. Let's take this
example to understand when it occurs. I launch the first VM using this
script :
#!/bin/sh
#ps ax | grep bhyve | awk '{ print $1; }' | xargs kill -9
setxkbmap it
vms="$(ls /dev/vmm/*)"
vncs="$(ps ax | awk '/vncviewer [0]/{print $6}')"
for vm in $vms; do
session="${vm##*/}"
echo "bhyve session = $session"
echo "vnc session = $vncs"
if ! printf '%s\n' "${vncs}" | grep "${session}"; then
printf 'VNC session not found,destroying
ghost vms\n'
bhyvectl --vm=$session --destroy
else
printf 'Found VNC session %s\n'
"${session},no ghost vms found,not destroying them"
fi
done
vmdisk=`geom disk list | awk '/^Geom name: /{d=$NF} /^ *ident: (NM13N4CZ)/
&& d{print d}'`
echo $vmdisk
vmdisk1=`geom disk list | awk '/^Geom name: /{d=$NF} /^ *ident:
(2015020204055E)/ && d{print d}'`
echo $vmdisk1

echo $vmdisk2

echo $vmdisk3

Windows 11 runs there and it works great. At this point,let's say that I
want to run the VM n. 2 without closing the first one and this time I
choose a Linux vm,that I launch using this script :
#!/bin/sh
setxkbmap it
vms="$(ls /dev/vmm/*)"
vncs="$(ps ax | awk '/vncviewer [0]/{print $6}')"
for vm in $vms; do
session="${vm##*/}"
echo "bhyve session = $session"
echo "vnc session = $vncs"
if ! printf '%s\n' "${vncs}" | grep "${session}"; then
printf 'VNC session not found,destroying
ghost vms\n'
bhyvectl --vm=$session --destroy
else
printf 'Found VNC session %s\n'
"${session},no ghost vms found,not destroying them"
fi

and boom. The first VM crash itself and close giving this error :

This is clearly a bug that should be fixed. Maybe @Corvin Köhne
<c.koehne@beckhoff.com> can help here.
