Subject: [PATCH] qemu: Add zPCI address definition check
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
We should ensure that QEMU supports zPCI when a zPCI address is defined
in XML and otherwise report an error. This patch introduces a generic
validation function qemuDomainDeviceDefValidateAddress() which calls
qemuDomainDeviceDefValidateZPCIAddress() if address type is PCI address.
