Unable to export/import Windows VM

How can we backup and restore windows vm in lxd?

The same way you would with a container:

lxc export <instance> <filename>
lxc import <filename>

I have tried like container and after import the vm start and it brings me recovery state.

Was the VM stopped when you exported it?

hafijaa · May 27, 2021, 12:28pm

yes

Any ideas @monstermunchkin , is this something you can test to see if its reproducible?

I split off this thread into its own topic and assigned it to @monstermunchkin for investigation.

I cannot confirm this.

Here’s what I did:

Install Windows 10 (repacked Win10_21H1_English_x64.iso using distrobuilder) and go through the configuration (keyboard layout, etc.) after the first reboot
Once logged in, shutdown the VM properly
Run lxc export win10
Run lxc import backup.tar.gz win10-restored
Run lxc start win10-restored --console=vga

I boots without any issues.

@hafijaa what storage backend are you using in LXD?

hafijaa · May 30, 2021, 5:54am

ZFS storage

stgraber · May 30, 2021, 7:19pm

@monstermunchkin can you test on zfs if you were using something else?

monstermunchkin · May 31, 2021, 11:27am

Tested it on ZFS. It works just fine.
