| 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.
