I have several VMs with disk passthrough that refuse to start after doing
[2020-10-09T12:44:33+0200] [ALPM] upgraded libvirt (6.5.0-1 -> 6.5.0-2)with error message
Unable to get devmapper targets for /dev/disk/by-id/ata-Samsung_SSD_860_EVO_1TB_[snip]: Datei oder Verzeichnis nicht gefunden(basically: file not found).
I have found two reports about this, including this one
https://www.reddit.com/r/VFIO/comments/ … devmapper/
which links to this change
https://github.com/archlinux/svntogit-c … d9db127101
but no solution. Except to downgrade to libvirt 6.5.0-1.
Is there a "correct" solution to this and can somebody please detail that solution?
I am assuming, that this is some kind of access rights problem. I am running qemu as unpriviliged user.
What i tried so far
Adding the devices to cgroup_device_acl in qemu.conf. This will yield the "Success" in the error message as seen in https://github.com/archlinux/svntogit-c … d9db127101
Adding the qemu user to to the disk group.
Thanks in advance, going to downgrade (and pin) now ...

Wow, that was fast. Thanks.
So i assume there will be a 6.5.0-x where this is resolved?
Marking as solved.
