[pve-devel] [PATCH] enable q35 machine support

[Alexandre DERUMIER]

>>Bus names are 'pcie.$bus'? But we use 'pci.$bus' inside code?

The main bus is a pci express bus.

default q35 chipset devices (ehci,audio,...), pciexpress passthrough use pcie.0


Others "classic" devices (virtio,ide,...) use pci.0|1|2, like before.
they are pci-bridges for this.



Note, It should be possible to plug "classic" devices on pcie.0 
but
I look the libvirt doc , it's not recommanded because:

- pcie.0 is not hotpluggable
- in the future it'll not be possible to connect  pci devices on pcie.0, but only pci-express devices

Bus names are 'pcie.$bus'? But we use 'pci.$bus' inside code?
