It can, however, open each /dev/vfio/NN group file only once each,

There can be unarguable reasons for PCI hotplug to fail as well
(attempting to plug to a bus that can't support it for one). The
difference here is that it's a failure that we expect to be transitory.

It's a different guest side interface, the H_TPM_COMM hypercall

You're correct. The difference originates at the hardware level. On
x86 the host always "owns" the PMU, and it requires explicit work in
KVM to make it available to the guest. On POWER, the guest owns t

Open Firmware (of which we have a couple of other partial
implementations used for other qemu platforms). U-Boot is somewhere in
between the two, a specific implementation that defines a fair bunch of

PAPR does not (and can't reasonably) use the pxb device. Instead to
allocate devices to different guest NUMA nodes they should be placed
on different vPHBs. Placing them on different PHBs by default allows
NUMA node to be assigned to those PHBs in a straightforward man

Alas, no, we only have 3 on KVM/qemu. Well, possibly you could do (2)
by plugging a bridge device using (3) then a device onto the bridge.
Whole PHB hotplug has never been implemented for qemu/KVM.. but we
probably want to.

easons to keep both updated. For pseries we have neither the impetus
nor the resources to maintain two different machine type variant,
where the only difference is between legacy PCI and weirdly presented
