Thanks - this got me past the original issue. What I did is I opened up Flatseal and granted access to all system files for Virtual Machine Manager.
However, now I’m stuck at a different point. I can get past where I choose how much memory, CPU, and disk storage to allocate, but when I get to Step 5 and click Finish,
This happens:
Unable to complete install: 'internal error: process exited while connecting to monitor: 2025-06-22T17:16:36.091623Z qemu-system-x86_64: -blockdev {"driver":"file","filename":"/run/media/myusername/path/to/installers/debian-12.11.0-amd64-netinst.iso","node-name":"libvirt-1-storage","read-only":true}: Could not open '/run/media/myusername/path/to/installers/debian-12.11.0-amd64-netinst.iso': Permission denied'

This message is talking about permission denied, so I checked the file permissions, and I saw that the ISO file is owned by the qemu user:
myusername@fedora:~$ ls -la /run/media/myusername/path/to/installers
total 101472336
drwxr-xr-x. 2 myusername myusername 4096 Jun 16 14:47 .
drwxr-xr-x. 6 myusername myusername 12288 Jul 29 2024 ..
-rw-r--r--. 1 myusername myusername 7547453440 Oct 17 2024 bazzite-gnome-stable.iso
-rw-r--r--. 1 qemu qemu 702545920 Jun 12 17:00 debian-12.11.0-amd64-netinst.iso
I changed it to myusername:
sudo chown myusername:myusername /run/media/myusername/path/to/installers/debian-12.11.0-amd64-netinst.iso
When I tried the same steps again, I got stuck in the same place and rerunning ls
showed that the ISO file’s ownership has reverted back to qemu
.
Any ideas?
Can you expand on this? I’m not sure what this means. Is it like instead of a full fledged password, just a four digit PIN or something? Thanks.
