Ages ago origCPU in domain private data was introduced to provide backward compatibility when migrating to an old libvirt, which did not support fetching updated CPU definition from QEMU. Thus origCPU will contain the original CPU definition before such update. But only if the update actually changed anything. Let's always fill origCPU with the original definition when starting a domain so that we can rely on it being always set, even if it matches the updated definition. This fixes migration or save operations with custom domain XML after commit v10.1.0-88-g14d3517410, which expected origCPU to be always set to the CPU definition from inactive XML to check features explicitly requested by a user. https://issues.redhat.com/browse/RHEL-30622 Signed-off-by: Jiri Denemark <jdenemar@redhat.com> Tested-by: Han Han <hhan@redhat.com> Reviewed-by: Peter Krempa <pkrempa@redhat.com> |

Libvirt API for virtualization
Libvirt provides a portable, long term stable C API for managing the virtualization technologies provided by many operating systems. It includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER Hypervisor.
For some of these hypervisors, it provides a stateful management daemon which runs on the virtualization host allowing access to the API both by non-privileged local users and remote users.
Layered packages provide bindings of the libvirt C API into other languages including Python, Perl, PHP, Go, Java, OCaml, as well as mappings into object systems such as GObject, CIM and SNMP.
