Re: [Xen-users] Auto revertable disk

I'd rather not use an LVM master but use vhd COW disks.

However, you've said "destroy it when done work". how do I detect the shutdown?
Or better still, is there a way to run a script before a domain is created?

It looks a bit hacky but I may be able to add something into one of the scripts in /etc/xen.
Are those scripts related to the deprecated xm?  I'd prefer to use what will be current, so that would not suit.

How do I create a Virtual Machine disk that when started the user can do whatever they like however,
when the domain ends (for any reason) the state of the disk is automatically reverted to it's original state.

I think this could be as easy as creating a copy on write VHD of the disk I want to use as the "clean state".
Then before starting the domain, delete the VHD and re-create it, then create the domain.

It's trivial to script this, but if the user was to "restart" then I want it reverted to.  So how do I detect a reboot etc?
