mandatory citrix server

[gregor]

Good day, two little questions,

I have some machines my students may play on and do whatever they want but I want alle the settings etc back during the night so:

1 I know for sure that I read it somewhere, but how to you make a mandatory file, So the machine will be exact the same after a reboot. I know you should at some rule in a config file but can't find i back

2 Is there a way to stop and start an machine in a script every night at 2 o'clock.

thnx

you can use base images for that. check out the man pages for qemu-img, it will tell you how to create a disk image that only saves the differences from a base image (qemu-img create -b <base image>).

you can then set up cronjobs to reboot the VMs at night... or rather create a script run by cron that does:

#!/bin/bash
qm shutdown -forcestop 1 $1
sleep 1 #for good measure
rm /path/to/your/vms/$1/vm-$1-disk-1.qcow2
qemu-img create -b /path/to/base-image /path/to/your/vms/$1/vm-$1-disk-1.qcow2
qm start $1

please note that this is the most rudimentary form of script. if you call it with a VMID, it will reboot that VM. this script needs a check if the VMID exists and other safety things like that (like... check whether the storage location is writeable and all these nice things youll want to check in a safe script)

PS: what does your question have to do with the thread subject (citrix)?

Thanks for the replay, I'm going to work on that. About your question, another title would be better i guess but I thought that go back to an image was called mandatory
