Virtualbox vmboot script

By nature

16. september 2012

Jeg har over en lengre periode brukt følgende script for å automagisk starte VM's ved boot av Ubuntu serveren min. Det stopper også VM's på en grei måte noe jeg gjerne vil beholde.

Men så har det seg slik at dette scriptet starter alle VM's jeg har. Dette synes jeg etterhvert er svært lite intressant da det i utgangspunktet er bare 1 VM jeg må starte ved boot.

Spørsmålet er da, hva skal jeg endre på i scriptet for å oppnå dette?

OBS: Jeg har kopiert og limt inn scriptet fra putty, så ikke sikkert det er 100% komplett, men jeg håper dere ser nok til å kunne hjelpe meg.

Vil det være nok å endre

function startService(){
for v in $ALLVMS; do
if [[ -n $($SU $VBOXMANAGE showvminfo $v) ]]; then
$echocmd "Waiting for VM \"$($SU $VBOXMANAGE list vms | grep $v | awk -F\" '{print $(NF -1)}')\" to power on..." && $SU $VBOXMANAGE startvm $v --type headless 1> /dev/null$
$echocmd "No Saved VMs to start!"
