did you find the cause for this yet? i'm running into the same error

Sadly I don't. Eventually I went through this and I cannot recall exactly how off the top of my head.

IIRC I had a mismatch in versions, i.e. I had updated the packages but I had the running processes linking older libs. Try restarting the qemu session before saving a domain again.

I see this error, too, when saving virtual machine (OpenSUSE Tumbleweed: qemu 6.1.0-33.1, libvirt 7.8.0-2.1).
I found out that save file is being written to /var/lib/libvirt/qemu/save, but it is removed before throwing exception. There is enough space for that file in filesystem.

I am having this same issue on QEMU emulator version 6.1.0 (openSUSE Tumbleweed). Same stacktrace I think, too.

i didn't manage fixing it yet, but apparently this is caused by a migration blocker when using QXL graphics.
This was reverted in this commit
the next qemu release should fix this, in theory compiling it yourself should too but i don't feel like bothering with that for now so i'll let one of you guys find out :^)

This gist and Qemu bug https://gitlab.com/libvirt/libvirt/-/issues/236 are of the same bug. @X41 could you pick that up as Qemu developer?

sorry about the confusion @Jiivee1 but i'm not a qemu dev 😅
and like i've said, this should be fixed already and rolled out in the next release (which should be mid december at the latest according to this)

EDIT: also i finally made myself compile things myself from git and saving with qxl works again!

Very nice to have found the actual issue, I did not think of looking in libvirt issue.

So what happened in my case was just that Void upgraded libvirt package underneat and I got the fix.

@X41 Thanks for clarification.

I can live by not using qxl for now and I can wait qemu 6.2.0 coming down to my distro. As being an ordinary user it is sometimes hard to figure out where the true bug is.
