Hi Michael,
To trigger this I just:
1. Boot the VM, command-line:
# ./qemu -drive file=disks/test.img,if=virtio,cache=none,aio=native \
-enable-kvm -m 1G -monitor stdio \
-netdev type=tap,vhost=on,id=guest0,script=qemu-ifup-switch \
-device virtio-net-pci,netdev=guest0 -cpu host
2. Once the VM is fully booted:
QEMU 1.3.50 monitor - type 'help' for more information
(qemu) q
qemu-qmp: /home/lcapitulino/work/src/qmp-unstable/hw/virtio-pci.c:535:
kvm_virtio_pci_irqfd_release: Assertion `ret == 0' failed.
~/work/virt/
Seems to be related with your latest pull request (commit 8e9a8681).
