Hi,
I know it's a little off topic, but
has anyone a good documentation for
the qemu-guest-agent ?
I'm aware of the following entry, but
it is not helpful at all:
http://wiki.qemu.org/Features/QAPI/GuestAgent
I'm looking for documentation on the following
topics:
install the guest-agent into a vm
architecture of the guest agent
building the guest-agent
I tried to build the whole qemu-thing
in a ubuntu 12.04. vm running on ovirt
but I'm not successfull.
I get the following error after invoking "make":
GEN trace/generated-tracers.c
CC hw/virtio/dataplane/vring.o
hw/virtio/dataplane/vring.c In function "vring_pop":
hw/virtio/dataplane/vring.c:400:5: error: "ret" may be used
uninitialized in this function [-Werror=uninitialized]
cc1: all warnings being treated as errors
make: *** [hw/virtio/dataplane/vring.o] Error 1
I would also like to know if you are aware of any prebuild packages
for ubuntu 12.04 (or later) or if there is documentation anywhere
on the net for which distributions you can download a rpm/deb package.
Thank you.

I didn't try that myself.
Good luck,

Hi,
and thanks for your fast reply, but you
are looking in the wrong direction.
I was talking about the _qemu_-guest-agent
not the ovirt-guest-agent.
afaik they are not similar but ovirt seems
to rebuild some of the capabilities which
qemu-guest-agent already has.
(Any reason why this is done btw?)
afaik they share e.g. the ability to
power down the vm.
but qemu-ga also will allow cpu-hotplug
and altering disk layout inside the guest
in the future.
I'm aware of your mentioned repository for
the ovirt-guest-agent and I already reported
that it works good so far (an offical repo would
of course be better).
I didn't find a repo for qemu-ga unfortunately.
Thanks anyway.

I see that it's packaged in Ubuntu:
https://launchpad.net/ubuntu/raring/+package/qemu-guest-agent
https://launchpad.net/ubuntu/raring/+source/qemu/1.4.0+dfsg-1expubuntu4
https://code.launchpad.net/ubuntu/raring/+source/qemu
and for that matter, Debian:

Thanks for the links, so this is at least
some good news.
However no package for ubuntu 12.04
I'll try to use these as backports, maybe that works.

ovirt-guest-agent codebase predates qemu-guest-agent (by several years).
as qemu-guest-agent adds functionality, we try to converge and support
it via qemu-guest-agent as well, which may allow deprecating that
functionality in ovirt-guest-agent in the future (tbd)

Hi Itamar,
thanks for pointing this out.
I didn't know the history of the code base.
It seems that there always will be a difference
in the functionality of qemu- and ovirt-agent.
So my conclusion and advice would be to keep
this duplicated functionality and, if possible,
extend ovirt-guest-agent to be a superset of
functions over qemu-guest-agent, thus avoiding
installation of both agents.
But I don't know if this is possible.
