hi, all:
i apply this patch, https://git.centos.org/blob/rpms!!qemu-kvm/6078803a0db76660aef491907f795bb23ad33357/SOURCES!kvm-virtio-error-out-if-guest-exceeds-virtqueue-size.patch;jsessionid=124pfc40q9ejezgb0b5qrnv6m#L33 .
but this patch always results in a bug(bug?). a vm always exits with '2016-10-17T07:33:40.393592Z qemu-kvm: Virtqueue size exceeded', if you suspend and resume . (please refer to https://wiki.openstack.org/wiki/Kvm-Pause-Suspend to see the definiton of suspend and resume in openstack). this operation is very commonly used in openstack. i am not sure if this patch is elegant .
what is your opinion?
thanks
