I had a look at the recent traffic on libvir-list and didn't see anything related so forwarding to libvirt-list and Eric who seems to have touched the file in question in the range. Ian.

maint: prefer enum over int for virstoragefile structs
For internal structs, we might as well be type-safe and let the compiler help us with less typing required on our part (getting rid of casts is always nice). In trying to use enums directly, I noticed two problems in virstoragefile.h that can't be fixed without more invasive refactoring: virStorageSource.format is used as more of a union of multiple enums in storage volume code (so it has to remain an int), and virStorageSourcePoolDef refers to pooltype whose enum is declared in src/conf, but where src/util can't pull in headers from src/conf.
* src/util/virstoragefile.h (virStorageNetHostDef) (virStorageSourcePoolDef, virStorageSource): Use enums instead of int for fields of internal types. * src/qemu/qemu_command.c (qemuParseCommandLine): Cover all values. * src/conf/domain_conf.c (virDomainDiskSourceParse) (virDomainDiskSourceFormat): Simplify clients. * src/qemu/qemu_driver.c (qemuDomainSnapshotCreateSingleDiskActive) (qemuDomainSnapshotPrepareDiskExternalBackingInactive) (qemuDomainSnapshotPrepareDiskExternalOverlayActive) (qemuDomainSnapshotPrepareDiskInternal): Likewise.

maint: shorten 'TypeType' function names
The VIR_ENUM_DECL/VIR_ENUM_IMPL helper macros already append 'Type' to the enum name being converted; it looks silly to have functions with 'TypeType' in their name. Even though some of our enums have to have a 'Type' suffix, the corresponding string conversion functions do not.
* src/conf/secret_conf.h (VIR_ENUM_DECL): Rename virSecretUsageType. * src/conf/storage_conf.h (VIR_ENUM_DECL): Rename virStoragePoolAuthType, virStoragePoolSourceAdapterType, virStoragePartedFsType. * src/conf/domain_conf.c (virDomainDiskDefParseXML) (virDomainFSDefParseXML, virDomainFSDefFormat): Update callers. * src/conf/secret_conf.c (virSecretDefParseUsage) (virSecretDefFormatUsage): Likewise. * src/conf/storage_conf.c (virStoragePoolDefParseAuth) (virStoragePoolDefParseSource, virStoragePoolSourceFormat): Likewise. * src/lxc/lxc_controller.c (virLXCControllerSetupLoopDevices): Likewise. * src/storage/storage_backend_disk.c (virStorageBackendDiskPartFormat): Likewise. * src/util/virstorageencryption.c (virStorageEncryptionSecretParse) (virStorageEncryptionSecretFormat): Likewise. * tools/virsh-secret.c (cmdSecretList): Likewise. * src/libvirt_private.syms (secret_conf.h, storage_conf.h): Export corrected names.

Continuing the work of consistent enum cleanups; this time in virstorageencryption.h.

qemu: Implement virDomain{Get,Set}Time
One caveat though, qemu-ga is expecting time and returning time in nanoseconds. With all the buffering and propagation delay, the time is already wrong once it gets to the qemu-ga, but there's nothing we can do about it.

Introduce virDomain{Get,Set}Time APIs
These APIs allow users to get or set time in a domain, which may come handy if the domain has been resumed just recently and NTP is not configured or hasn't kicked in yet and the guest is running something time critical. In addition, NTP may refuse to re-set the clock if the skew is too big.
In addition, new ACL attribute is introduced 'set_time'.
