qemu supports this enlightenment since version 7.10.
From the qemu commit:
Hyper-V specification allows to pass parameters for certain hypercalls
using XMM registers ("XMM Fast Hypercall Input"). When the feature is
in use, it allows for faster hypercalls processing as KVM can avoid
reading guest's memory.

This capability tells us whether given QEMU binary supports the
'-machine xxx,i8042=on/off' toggle used to enable/disable PS/2
controller emulation.
A few facts:
- This option was introduced in QEMU 7.0 and defaults to 'on'
- QEMU versions before 7.0 enabled i8042 controller emulation implicitly
- This option (and i8042 controller emulation itself) is only supported
by descendants of the generic PC machine type (e.g. i440fx, q35, etc.)

Since -netdev user can be disabled during QEMU compilation, we
can't blindly expect it to just be there. We need a capability
that tracks its presence.
For qemu-4.2.0 we are not able to detect the capability so do the
next best thing - assume the capability is there. This is
consistent with our current behaviour where we blindly assume the
capability, anyway.

Check whether the qemu binary supports the vdpa block driver. We can't
rely simply on the existence of the virtio-blk-vhost-vdpa block driver
since the first releases of qemu didn't support fd-passing for this
driver. So we have to check for the 'fdset' feature on the driver
object. This feature will be present in the qemu 8.1.0 release and was
merged to qemu in commit 98b126f5.
