Some of our really old APIs are missing @flags argument. We introduced their variants with "Flags" suffix and wired some logic into virsh to call the new variant only if necessary. This enables virsh to talk to older daemon which may be lacking new APIs. However, in case of cmdSetmem() we are talking about v0.1.1 (virDomainSetMemory()) vs. v0.9.0 (virDomainSetMemoryFlags()) and in case of cmdSetmaxmem() we are talking about v0.0.3 (virDomainSetMaxMemory()) vs v0.9.0 (virDomainSetMemoryFlags()). Libvirt v0.9.0 was released more than 10 years ago and recently we dropped support for RHEL-7 which has v4.5.0 (released ~3 years ago). Thus it is not really necessary to have support in virsh for such old daemons. Signed-off-by: Michal Privoznik <mprivozn@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.
