qtest/libqos: Finding the free PCI slots in a qtest instance

[Sheindy Frenkel]

Hi,

I'm trying to find out how I can get the free PCI slots in a qtest code.

I want to assign a PCI device to a qtest-mode VM. If I assign this device to an unavailable address in the qemu process, I get this assertion: PCI: slot x function y not available for z.

However, I couldn't find a function in the qtest API that maintains the free slots list, it seems this error is coming from the qemu process, and qtest can't control it.

Could qtest API expose a function to access the free PCI slots in the guest? is there any existing function that can help maintain this list?

Thanks,

Sheindy
