Subject: [PATCH] conf: add default USB controller in qemu post-parse callback
|
|
|
|
The parser shouldn't be doing arch-specific things like adding in
|
|
implicit controllers to the config. This should instead be done in the
|
|
hypervisor's post-parse callback.
|
|
|
|
This patch removes the auto-add of a usb controller from the domain
|
|
parser, and puts it into the qemu driver's post-parse callback (just
|
|
as is already done with the auto-add of the pci-root controller). In
|
|
the future, any machine/arch that shouldn't have a default usb
|
|
controller added should just set addDefaultUSB = false in this
|
|
function.
|
|
|
|
We've recently seen that q35 and ARMV7L domains shouldn't get a default USB
|
|
controller, so I've set addDefaultUSB to false for both of those.
|
|
|
|
(cherry picked from commit c66da9d224ffba1d972beaf049c00dbebda4e8ea)
