This is a new one for us.

Jan 23 15:29:39 QEMU[284972]: virtio-blk failed to set host notifier (-24)

Are we hitting a simple limit here? In the last decade of using proxmox I've never hit this, so I wanted to run it by the community first.

I will give that a try. Do you guys plan on applying the patch?

Hopefully it gets some traction, the work arounds don't seem to work when live migrating the VM. I have to stop/start the VM or use prlimit to change the values manually.
