Having a strange issue.... Im working with OS stein and things are going pretty smoothly but when i request an instance to reboot it sits for a while and actually restarts the physical host.. This seems to be only happening with the hosts that im doing PCI pass through with so im guessing it has something to do with this but i dont see anything in the logs anywhere. Im thinking maybe its a bios setting? The strange thing is that if i log in to the instance and perform a reboot from there it reboots just fine with out rebooting the instance...

This is the only thing im seeing in the log..

WARNING nova.virt.libvirt.driver [req-2addcc88-6bdc-4dd5-8f4b-d106bbe5d9ef f349ba76475e4d33b3d5f62c6b352c75 a381d1588dd645ec9b66ae1bb3787a04 - default default] [instance: ef6a9854-5cad-4272-b4b3-36d79f603256] Failed to soft reboot instance. Trying hard reboot.

Any ideas?

I've got the same issue, but only on certain hosts for some reason. Issue was in Rocky as well. A while back someone suggested setting options allow_unsafe_assigned_interrupts=1 to a .conf file in /etc/modprobe.d/. This didn't help me, but sharing in case it helps you.
