I am attempting to make use of '-pcidevice' on my system, but have run

KVM-84
You mean both userspace and kernel module built externally?
Yes, I built both from the kvm-84.tar.gz package.

Failed to assign irq for "02:00.0": Input/output error
Perhaps you are assigning a device that shares an IRQ with another device?
any info in dmesg? what's lspci -t show?
dmesg gives:
