No available PCI hotplug slots could be found

I have 9 directories mounted in a debian bookworm VM. Now i get this msg and cant add any more. Never had this issue before. Also used LXD before.

What version?

That sounds a lot like a bug I fixed a couple of months ago.

Incus 6.6, host is ubuntu 24.04. Guest is debian bookworm

Did you add those after boot?

We have 8-10 hotplug PCI slots set up at boot, so you can hotplug that many devices after boot.
If you need more, rebooting the VM will basically set a new baseline so you’ll then be able to add another 8-10 on top of whatever was there after the reboot.

Oh yes i added them after boot. Il just shut it down and add the disks i need. Thx!
