Subject: [Qemu-devel] [PATCH 0/2] virtio-pci: fix abort when fail to allocate ioeventfd
Date: Tue, 13 Mar 2012 18:42:22 +0800 [thread overview]
Message-ID: <20120313103602.8741.71939.stgit@dhcp-8-167.nay.redhat.com> (raw)
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
