[virtualisation] [issue] Windows 10 image stops loading when .img lies in a different partition

ernesto.pozzoni

Hi, thanks in advance for your support.

• QEMU / KVM + Virtual Machine Manager

• I'd like to store my .img file containing Windows 10 I use for job under /mnt/LCS/ which lies in a different partition, instead of the usual /var/lib/libvirt/images/ which lies in the same main root / of where also there is the virtualisation tools.

• The partition where the image is stored contains the .img only, and there are 2GB left as a free space.

• As a check, a copy of the same image is stored in $HOME/Download/

• Both the mentioned paths have the same user and groups ownership (my user), and the same xrw permissions.

• The integrity of the dedicated partition's file systems looks OK

Outcome

• The image in $HOME/Download/ works regularly.

• The image in /mnt/LCS/ under a different partition stops loading after few seconds, when the Windows splash is already displayed.

FYI, this is what dmesg says. I don't know how much it can be useful.

Any suggestion to help me to sort that out please?

Perhaps some issue with the file system's permissions of the dedicated partition?
Perhaps more free space is necessary in the dedicated partition?
What else?
