Description Vinzenz Feenstra [evilissimo] 2013-12-16 12:05:15 UTC 
The oVirt Guest Agent needs to be packaged for and ported to Ubuntu
Comment 1 Brook Harty 2013-12-16 17:46:00 UTC 
Yes, we need ovirt-agents for Ubuntu 12 LTS and older versions, I've migrated old versions EOL'ed versions of Ubuntu to RHEVM...

If the linux ovirt-agent package can be made to install without dependencies the better.
Comment 2 Sven Kieske 2014-01-08 12:40:23 UTC 
What needs to be done to finish this?
The PPA works quite well for me on ubuntu 12.04. server:
https://launchpad.net/~zhshzhou/+archive/vdsm-ubuntu
Comment 3 Vinzenz Feenstra [evilissimo] 2014-02-17 07:00:08 UTC 
Zhou Zheng Sheng generously built the a new version of the ovirt-guest-agent and pushed it to his PPA account.

https://launchpad.net/~zhshzhou/+archive/vdsm-ubuntu
Comment 4 Sven Kieske 2014-02-17 08:09:19 UTC 
Any plans on getting this into "official" ubuntu /debian repos?
I know there needs something to be done for debian but the old version worked
well on ubuntu.
Comment 5 Jiri Belka 2014-02-17 14:41:37 UTC 
Broken, ovirt-guest-agent_1.0.9.20140216.git5168c4-1ppa1_all.deb

Something is broken because postinstall part did not make successfully /dev/virtio-ports/com.redhat.rhev.vdsm file/symlink.

Because you don't explicitly depend on existing virtio_console module, which is shipped with linux-image-extra-$ver-generic package.

Change control file for packaging the app.

Comment 6 Zhou Zheng Sheng 2014-02-18 04:09:23 UTC 
Actually install the latest linux-generic would also install linux-image-extra-3.11.0-15-generic as a dependency, and on my Ubuntu 13.10, it shows the following.

root@u1310:~# aptitude why linux-image-extra-3.11.0-15-generic
i   linux-generic       Depends linux-image-generic (= 3.11.0.15.16)
i A linux-image-generic Depends linux-image-extra-3.11.0-15-generic

The problem is that previous release of the linux-image-generic does not depend on linux-image-extra-$ver-generic. As I tested ovirt-guest-agent on the latest kernel shipped in Ubuntu, I didn't find this problem because linux-image-extra-3.11.0-15-generic was installed automatically.

I think it's a Ubuntu bug. In previous release of linux-image-extra-$ver-generic, say linux-image-extra-3.11.0-12-generic, if you show its information using aptitude.

root@u1310:~# aptitude show linux-image-extra-3.11.0-12-generic
... blah ...
 You likely do not want to install this package directly. Instead, install the linux-generic meta-package, which will ensure that upgrades work correctly, and that supporting
 packages are also installed.

It implies that linux-image-extra-3.11.0-12-generic should gets installed if linux-generic is installed. So if you install Ubuntu as normal, the virtio_console module should be already installed.
Comment 7 Jiri Belka 2014-02-18 08:48:22 UTC 
I installed 13.10 as minimal install from iso. If it works with whole Ubuntu ecosystem it's ok but you have to explicitly depend on what is explicitly needed. Anyway, if they offer some kind of 'minimal installation' or 'minimal installation for virtual machine' (this options can been seen in iso boot menu) as I used, it must work on such setup.

FYI ovirt-guest-agent won't work on LTS as there's no qemu-guest-agent. But this is another topic.

When got this dependency introduced?
I have working installations of ovirt guest agent with ubuntu server 12.04 lts
installed guest agent version is:
1.0.8.201309301944.gitb7f8f2-1ppa1

this version did not require qemu-guest-agent.

why do you break existing behaviour/ working installations?
Comment 9 Zhou Zheng Sheng 2014-02-18 10:38:57 UTC 
As I tested, the ubuntu 13.10 server ISO installs linux-generic, so linux-image-extra-$ver-generic is also installed.

The package description of linux-image-extra-$ver-generic implies that it's always installed if the linux-generic is installed, and it does not suggest us install it directly. This means it's bind to kernel package, and even if we want to add a dependency, we should depend on the linux-generic meta package.

I found that regardless of the kernel image version, when linux-generic is installed, linux-image-extra is always installed. This is true even for old release such as linux-image-extra-3.11.0-12-generic, it depends on linux-image-extra-3.11.0-12-generic as long as linux-generic is installed.

In this case, I think we should add the meta package linux-generic to our dependency.

No it did not require it before, but because we introduced a new feature to oVirt it was required to have the qemu-guest-agent for freezing and thawing the filesystem.

The problem what you call breaking is that we do not have currently different packages for different versions of Ubuntu.
We could take care of that if we would, but we don't and there's no problem removing the dependency of the qemu-guest-agent and rebuilding the package, but for the Backup feature to work reliably it's necessary at the moment.

The problem i am having with the debian packaging system is that I don't know how to express such conditions in the build script. It seems to me like I would have to maintain two different sets of files in order for this to work.


See for the Backup feature: BZ#1054231
See for the qemu-ga requirement: BZ#1055524
Comment 11 Zhou Zheng Sheng 2014-02-20 04:59:52 UTC 
@Jiri Belka:

Just before I am to submit a fix to add dependency on linux-generic, I tried installing Ubuntu 13.10 from the minimal CD ISO. In the package selection stage, I didn't select anything. After the successful installation, I login to the system and find that virtio_console.ko is installed. linux-generic is also installed. Would you tell me how did you setup the system without linux-generic? Could you try to install linux-generic on you minimal system, and see if it installs virtio_console.ko?
Comment 12 Jiri Belka 2014-02-20 11:50:55 UTC 
I tried against Ubuntu Server 13.10 - minimal install for virtual machine. There is *NO* linux-image-extra* package!

Hi, I tried again using the server edition ISO. On the package selection stage, it lists "OpenSSH server", "Virtualization Host" and so on. I didn't select any of them. After installation, I found linux-image-extra was installed. I want to know how you install a minimal server so that I can try my self. Do you mind describing the detailed step, including the libvirt XML or qemu arguments?

Could you also have a try on installing the package linux-generic and see if linux-image-extra is installed? If we add new dependency, I think linux-generic should be the correct one.

Please report this to the maintainer of the qemu-guest-agent on Ubuntu. Obviously there's nothing I can do here.
Comment 17 Michal Skrivanek 2014-03-31 09:38:30 UTC 
as per comment #9, we should add the meta package linux-generic to our dependency, and perhaps remove the dependency on qemu-ga

Comment 20 Jiri Belka 2014-05-22 09:55:50 UTC 
Ubuntu has crazy way to manage kernel/modules:

- 12.04 virtio_console is module in linux-image-$rel-generic
- 13.10 virtio_console is module in linux-image-$rel-extra (IIRC)
- 14.04 virtio_console is built-in in

...and not talking about specialized kernels like 'virtual'. GA depens on linux-image-generic which would mean during installation it would install newer kernel then currently loaded.

OK as people should do reboot after kernel circus and it works OK after reboot. When 13.10 is OOS I think dependency on kernel should be dropped.

this still bites me, maybe someone can explain those dependencies to me, my
situation:

ubuntu 12.04 guest
guest agent version: 1.0..9.1-2.1
installed kernels before I install the guest agent:
linux-image-3.8.0-29.42~precise1
installed kernels after I install the guest agent:
linux-image-3.8.0-29.42~precise1
linux-image-3.2.0-64.97

is this pulled in because of virtio_console ? is there no way to add this module
in another way (load it manually via /etc/modules ?)
Comment 23 Vinzenz Feenstra [evilissimo] 2014-06-25 11:11:06 UTC 
Well loading the module is not everything. It's mainly about the plugin being there and the guest agent needs to depend on it.
However having an older version of the kernel version installed instead is bad though. Please create a new bug for this.
Thanks.
Comment 24 Jiri Belka 2014-06-25 11:26:32 UTC 
It will end like vmware tools which have binary modules for all supported Linux distributions and if not found, then it compiles on-fly ones for current version :)
