From: "Michael S. Tsirkin" <m...@redhat.com> commit 62c96360ae7f2c7a8b029277fbb7cb082fdef7fd virtio-pci: fix level interrupts only helps systems without irqfd: on systems with irqfd support we passed in flag requesting irqfd even when msix is disabled.
As a result, for level interrupts we didn't install an fd handler so unmasking an fd had no effect. Fix this up. Cc: qemu-sta...@nongnu.org Signed-off-by: Michael S.
