Disk modifications after rebooting

[anthon]

Hello everyone

I'm switching from ESXI to Proxmox

Everything is ok but I'm missing a function I had on ESXI, having disk changes not persistent after a reboot.
Is there such option with Proxmox, a way to make every disk modifications not persistent after rebooting ?

I'm running Proxmox 4.3-1 with storage on the provisioned LVM

Regards

Hi,

can you explain exact what you exactly mean by disc changes?

Hello Wolfgang

What I mean is your disk got a fixed state you cannot alter or change after activating this option.
Looks like a kind of snapshot that capture all writes to the disk during the session to restore the original state after shutting down or resetting the machine.

Sometimes I need this function for boot-disk to avoid updates made by the OS.
Also for application testing, a new system configuration, a big change somewhere...

The disk is still writable but with this option turned ON, changes are logged and removed after a reset.

Regards,

Anthon

What you describe is just a snapshot, isn't it?

Yes I find it on VMWare docu it is a snapshot feature.
On Proxmox you have rollback manually.

Ok thanks tscganness and wolfgang, i got it now.
It's a snapshot but per disk and not for full VM and it's not implemented in Proxmox.
