#------------------------------------------------------------------------------#
#
# Dieses Skript hilt sich das neueste FreeBSD-RAW-Image und startet es mit Bhyve.
# Zu diesem Zweck wird auch ein TAP angelegt, wenn es nicht schon da ist und
# zur Brücke hinzugefügt.

VERSIN="2024021700"
 
RAM="1G"
NIC="tap10"
 
### wenn das NIC bereits in Nutzung ist, wird abgebrochen
ifconfig ${NIC} | grep -F 'Opened by PID ' && (echo "Das für diese VM vorgesehene NIC wird z.Z. benutzt."; exit 11)
 
#------------------------------------------------------------------------------#
 
### neuestes STABLE-Release-Namen auslesen
STABLERELEASE="$(links -dump https://download.freebsd.org/snapshots/VM-IMAGES/ | awk '/STABLE/{sub("/",""); print $1}' | sort -nr | head -n1)"
 
### wenn eine VM mit diesem Namen bereits läuft, dann wird abgebrochen
if [ -e /dev/vmm/FreeBSD-${STABLERELEASE} ] ; then
	echo "Es läuft bereits eine VM mit diesem Namen."
	exit 12
fi
 
### neuestes STABLE-Image saugen
FETCH_IMG="$(links -dump https://download.freebsd.org/snapshots/VM-IMAGES/${STABLERELEASE}/amd64/Latest/ | awk '/[.]raw[.]xz/{print $1}')"
DISKNAME="$(echo "${FETCH_IMG}" | rev | sed 's/[^.]*[.]//' | rev)"
#
#rm -f ${DISKNAME}
if [ -e "${DISKNAME}" ] ; then
	echo "Es gibt noch kein neues Release."
	echo "Es wird das vorhandene gestartet..."
else
	rm -f ${FETCH_IMG}
	fetch https://download.freebsd.org/snapshots/VM-IMAGES/${STABLERELEASE}/amd64/Latest/${FETCH_IMG}
 
	### Image entpacken
	unxz -v ${FETCH_IMG}
fi
 
### Netzwerkanbindung
ifconfig bridge0  || ifconfig bridge create
ifconfig ${NIC} || ifconfig ${NIC} create
ifconfig bridge0 | grep -F "member: ${NIC} " || ifconfig bridge0 addm ${NIC}
 
### NIC mit Default-Route (ins Internet???) ermitteln
INTERNETNIC="$(route get default | awk '/interface:/{print $NF}')"
if [ x = "x${INTERNETNIC}" ] ; then
	echo 'Es ẃurde keine NIC mit Default-Route gefunden!'
	echo 'Die VM wird versuchen sich eine IP-Adresse per DHCP vom Host (per lo0) zu holen.'
	ifconfig bridge0 | grep -F "member: lo0 " || ifconfig bridge0 addm lo0
else
	ifconfig bridge0 | grep -F "member: ${INTERNETNIC} " || ifconfig bridge0 addm ${INTERNETNIC}
fi
 
### VM starten
echo "sh /usr/share/examples/bhyve/vmrun.sh -m ${RAM} -t ${NIC} -d ${DISKNAME} FreeBSD-${STABLERELEASE}"
screen -S FreeBSD-${STABLERELEASE} sh /usr/share/examples/bhyve/vmrun.sh -m ${RAM} -t ${NIC} -d ${DISKNAME} FreeBSD-${STABLERELEASE}
 
### Hinweise zum sauber machen
echo "
ifconfig -a
ifconfig bridge0 deletem ${NIC}
ifconfig ${NIC} destroy
ifconfig bridge0 destroy
"

Device is mounted read-write; resizing will result in temporary write suspension for /.
It's strongly recommended to make a backup before growing the file system.
OK to grow filesystem on /dev/gpt/rootfs, mounted on /, from 5.0GB to 19GB? [yes/no] yes
growfs: no room to allocate last cylinder group; leaving 7.6MB unused
