I think I'm hitting this previous regression, I see this in my libvirt log: kvm_mem_ioeventfd_add: error adding ioeventfd: File exists And a backtrace as seen here https://paste.fedoraproject.org/477562/88144131/ So I merge this tag to try to resolve it, now I get qemu segfaulting bisected to: commit a6d8372bc6764ee279b473d13ff4ecc8acb7a978 Author: Cao jin Date: Sat Nov 5 10:07:21 2016 +0800 hcd-xhci: check & correct param before using it And if I revert that, vhost still fails with: qemu-system-x86_64: /net/gimli/home/alwillia/Work/qemu.git/memory.c:2012: memory_region_del_eventfd: Assertion `i != mr->ioeventfd_nb' failed. So I think this does not fix the previous regression and adds a new one :-\ Thanks, Alex
