Comment 5 for bug 1826422

ok, so, if I understand correctly, the workaround is:

- set `x-no-kvm-intx=on` and enable MSI in the guest (via regedit or module params)

which may lead to a performance regression (at least under certain circumstances).

Is it therefore preferrable, performance and configuration-wise, to use QEMU 3.1.0, if there are no 4.0.0 feature requirements, until this issue is sorted out?
