I'm not sure what you're referring to, so could you be more specific, so we can work from there and find the right solution?

But I doubt the qemuMonitorOpenUnix bit would disappear with the mentioned libvirt fix. But I will need a fresh and complete daemon log to investigate further, as well as libvirtd.conf and qemu.conf (just in case), so that I can compare to my environment, since I'm not able to reproduce this.

It's indeed odd that you don't see the same behaviour when running qemu as root. As I said, I will need the daemon log and preferably the configs as well to investigate further.
