File 6b5c6314-qemu-irqchip.patch of Package libvirt
commit 6b5c6314b2f7a3b54c94a591e6b0dcd13ef1c6ce Author: Ján Tomko <jtomko@redhat.com> Date: Fri Mar 17 08:26:49 2017 +0100 qemu: format kernel_irqchip on the command line Add kernel_irqchip=split/on to the QEMU command line and a capability that looks for it in query-command-line-options output. For the 'split' option, use a version check since it cannot be reasonably probed. https://bugzilla.redhat.com/show_bug.cgi?id=1427005 Index: libvirt-3.3.0/src/qemu/qemu_capabilities.c
