Repost of
http://www.redhat.com/archives/libvir-list/2010-February/msg00177.html
The virsh output is now scaled to show KB/MB as needed, instead of
always bytes.
The public API gained extra status
VIR_DOMAIN_JOB_COMPLETED = 3, /* Job has finished, but isn't cleaned up */
VIR_DOMAIN_JOB_FAILED = 4, /* Job hit error, but isn't cleaned up */
VIR_DOMAIN_JOB_CANCELLED = 6, /* Job was aborted, but isn't cleaned up */
to allow to more easily detecting end of a job, once we allow
for truely async usage
9:56 a.m.
New subject: [libvirt] [PATCH 1/9] Introduce public API for domain async job handling
Introduce a new public API that provides a way to get progress
info on currently running jobs on a virDomainpPtr. APIs that
are initially within scope of this idea are
virDomainMigrate
virDomainMigrateToURI
virDomainSave
virDomainRestore
virDomainCoreDump
These all take a potentially long time and benefit from monitoring.
The virDomainJobInfo struct allows for various pieces of information
to be reported
- Percentage completion
- Time
- Overall data
- Guest memory data
- Guest disk/file data
* include/libvirt/libvirt.h.in: Add virDomainGetJobInfo
* python/generator.py, python/libvirt-override-api.xml,
python/libvirt-override.c: Override for virDomainGetJobInfo API
* python/typewrappers.c, python/typewrappers.h: Introduce wrapper
for unsigned long long type

The unit is more a question, I don't see an use right now, but
it sounds like it can make the API more flexible if we want to use
it for "something else"
Basically looks fine ACK,

I wonder if we should not somehow provide an unit for the items being
measured. Maybe we don't want bytes in the future
The idea here is that the 'mem' and 'file' fields are always in bytes.
The 'data' field units are defined by the type of job being executed,
though effectively they're always bytes too.

New subject: [libvirt] [PATCH 4/9] Add QEMU driver support for job info on migration ops
Introduce support for virDomainGetJobInfo in the QEMU driver. This
allows for monitoring of any API that uses the 'info migrate' monitor
command. ie virDomainMigrate, virDomainSave and virDomainCoreDump
Unfortunately QEMU does not provide a way to monitor incoming migration
so we can't wire up virDomainRestore yet.
The virsh tool gets a new command 'domjobinfo' to query status
* src/qemu/qemu_driver.c: Record virDomainJobInfo and start time
in qemuDomainObjPrivatePtr objects. Add generic shared handler
for calling 'info migrate' with all migration based APIs.
* src/qemu/qemu_monitor_text.c: Fix parsing of 'info migration' reply
* tools/virsh.c: add new 'domjobinfo' command to query progress

Yeah, the public API comment was wrong - we were passing milliseconds out
to the client app, and virsh is processing it as milliseconds.

the request and when it takes effect, probably not a big deal

Migration still starts immediately, we merely have a 1/2 second delay
for detecting its completion. We need to improve this regardless though
since migraiton is supposed to be seemless !

Ah okay :-) so fix for 1/9 accordingly, and well after all my
comment about units in the API was kind of right ...

I would feel a bit better if we could add a flags there for future
extensions, like POSIX kill() ended up with many different semantics
we may have to refine at some point.
