From: Halil Pasic <pa...@linux.vnet.ibm.com> The commit 8dfbaa6ac ("virtio-ccw: introduce ccw specific queue limit") did not touch the sanity check for the vector argument of the method virtio_ccw_notify, despite intended as seen from https://lists.nongnu.org/archive/html/qemu-devel/2015-04/msg02705.html To be able to scale number of virtqueues using the constant this sanity check needs to be altered.
