[Qemu-devel] [PATCH 0/2] virtio-pci: fix abort when fail to allocate ioeventfd

[Amos Kong]

Boot up guest with 232 virtio-blk disk, qemu will abort for fail to
allocate ioeventfd. This patchset changes kvm_has_many_ioeventfds(),
and check if available ioeventfd exists. If not, virtio-pci will
fallback to userspace, and don't use ioeventfd for io notification.

Amos Kong (2):
      return available ioeventfds count in kvm_has_many_ioeventfds()
      virtio-pci: fallback to userspace when there is no enough available 
ioeventfd
