How to mount App-VMs from Outside qubes

[Dieter]

Hi,

I tried accessing data on an old qubes (3.2) drive that doesnt boot
anymore(stuck after decryption with a black screen with blinking _)
using this documentation article.

https://www.qubes-os.org/doc/mount-from-other-os/

However after decryption I only see the lvms "qubes_dom0-swap" and
"qubes_dom0-root" 

reading from dom0 is no problem but how can I access the other VMs?

(I accessed the drive via a live linux so I didnt rename the VG)

kind regards,

dieter

mount the dom0 root volume
check for .img files under /var/lib/qubes/

these are loop-mountable volumes

you can dd them to blockdevices, or use as-is.
private volumes should be usable on qubes 4.0 unless they contain
fancy configuration.

if you want to copy them around, beware of them being sparse files.
(== unless you use some copy tooling that can handle sparse files,
they will take a lot more space after copying than before)

Doesn't that depend on the storage pool being used? Your instructions
should be valid for file storage pools.

However with Qubes 4 LVM thin storage pools became the default. You
should be able to find instructions on this forum; there's also [1]
describing how to do it from dom0.

Its a Qubes 3.2 drive.
