[Engine-devel] Cloud-Init integration
by Greg Padgett
Hi Everyone,
I'd like to propose a feature we've been doing some investigation into,
which is to integrate cloud-init support into oVirt.
Cloud-init is used to help provision new Linux systems by setting the
hostname, ip, ssh keys, timezone, injecting files, and more. It's used by
OpenStack (amongst others) now, and has a lot of features that may be
helpful to our users.
Details are still evolving, but for more info please see the wiki page:
http://www.ovirt.org/Features/Cloud-Init_Integration
All feedback is welcome!
Thanks,
Greg

[Engine-devel] Proposal VDSM <=> Engine Data Statistics Retrieval Optimization
by Vinzenz Feenstra
This is a multi-part message in MIME format.
--------------020305070807050907000005
Content-Type: text/plain; charset=ISO-8859-1; format=flowed

Please find the prettier version on the wiki:
http://www.ovirt.org/Proposal_VDSM_-_Engine_Data_Statistics_Retrieval
Proposal VDSM - Engine Data Statistics Retrieval
VDSM <=> Engine data retrieval optimization
Motivation:
Currently the RHEVM engine is polling the a lot of data from VDSM every
15 seconds. This should be optimized and the amount of data requested
should be more specific.
For each VM the data currently contains much more information than
actually needed which blows up the size of the XML content quite big. We
could optimize this by splitting the reply on the getVmStats based on
the request of the engine into sections. For this reason Omer Frenkel
and me have split up the data into parts based on their usage.
This data can and usually does change during the lifetime of the VM.
Rarely Changed:
This data is change not very frequent and it should be enough to update
this only once in a while. Most commonly this data changes after changes
made in the UI or after a migration of the VM to another Host.
*Status* = Running
*acpiEnable* = true
*vmType* = kvm
*guestName* = W864GUESTAGENTT
*displayType* = qxl

*displaySecurePort* = 5903
*username* = user@W864GUESTAGENTT
*clientIp* =
*lastLogin* = 1361976900.67
Often Changed:
This data is changed quite often however it is not necessary to update
this data every 15 seconds. As this is cumulative data and reflects the
current status, and it does not need to be snapshotted every 15 seconds
to retrieve statistics. The data can be retrieved in much more generous
time slices. (e.g. Every 5 minutes)
*network* = {'vnet1': {'macAddr': '00:1a:4a:22:3c:db', 'rxDropped': '0', 'txDropped': '0', 'rxErrors': '0', 'txRate': '0.0', 'rxRate': '0.0', 'txErrors': '0', 'state': 'unknown', 'speed': '100', 'name': 'vnet1'}}
*disksUsage* = [{'path': 'c:\\', 'total': '64055406592', 'fs': 'NTFS', 'used': '19223846912'}, {'path': 'd:\\', 'total': '3490912256', 'fs': 'UDF', 'used': '3490912256'}]
*timeOffset* = 14422
*elapsedTime* = 68591
*hash* = 2335461227228498964
*statsAge* = 0.09 # unused
Often Changed but unused
This data does not seem to be used in the engine at all. It is *not*
even used in the data warehouse.
*memoryStats* = {'swap_out': '0', 'majflt': '0', 'mem_free': '1466884', 'swap_in': '0', 'pageflt': '0', 'mem_total': '2096736', 'mem_unused': '1466884'}
*balloonInfo* = {'balloon_max': 2097152, 'balloon_cur': 2097152}
*disks* = {'vda': {'readLatency': '0', 'apparentsize': '64424509440', 'writeLatency': '1754496', 'imageID': '28abb923-7b89-4638-84f8-1700f0b76482', 'flushLatency': '156549', 'readRate': '0.00', 'truesize': '18855059456', 'writeRate': '952.05'}, 'hdc': {'readLatency': '0', 'apparentsize': '0', 'writeLatency': '0', 'flushLatency': '0', 'readRate': '0.00', 'truesize': '0', 'writeRate': '0.00'}}
Very frequent uppdates needed by webadmin portal:
This data is mostly needed for the webadmin portal and might be required
to be updated quite often. An exception here is the statsAge field,
which seems to be unused by the Engine. This data could be requested
every 15 seconds to keep things as they are now.
*cpuSys* = 2.32
*cpuUser* = 1.34
*memUsage* = 30
Proposed Solution for VDSM & Engine:
We will introduce new optional parameters to getVmStats, getAllVmStats
and list to allow a finer grained specification of data which should be
included.
*Parameter:* *statsType*=/*<string>*/ (getVmStats, getAllVmStats only)
*Allowed values:*
* full (default to keep backwards compatibility)
* app-list (Just send the application list)
* rare (include everything from rarely changed to very frequent)
* often (include everything from often changed to very frequent)
* frequent (only send the very frequently changed items)
*Parameter:* *clientId*=*<string>* The client id is specified by the
client and should be unique however constantly used.
*Parameter:* *diff*=*<boolean>* In combination with the clientId VDSM
will send only differences to the previous request from the named
clientId. (if diff=true)
Additional Change:
Besides the introduction of the new parameters for list, getVmStats and
getAllVmStats it might make sense to include a hash for the appList into
the rarely changed section of the response which would allow to identify
changes and avoid having to sent the complete appList every so often and
only if the hash known to the client is outdated.
*Note:* The appList (Application List) reported by the guest agent could
be fully implemented on request only, as long as the guest agent
installed supports this. As there seems to be a request to have the
complete list of installed applications on all guests this data could be
quite extensive and a huge list. On the other hand this data is only
rarely visible and therefore it should not be requested all the time and
only on demand.
Improvement of the Guest Agent:
As part of the proposed solution it is necessary to improve the guest
agent as well. For the full application list there should be implemented
a caching system which will be fully reactive and should not poll the
application list for example all the time. The guest can create a
prepared data file containing all data in the JSON format (as used for
the communication with VDSM via VIO) and just have to read that file
from disk and directly sends it to VDSM. However it is quite possible
that this list is to big and it might have to be chunked into pieces.
(Multiple messages, which would have to be supported by VDSM then as
well) The solution for this is to make VDSM request this data and it
will retrieve the data necessary on request only.

[Engine-devel] ovirt user portal and attach a cd
by Andrej Bagon
Hi all,
we would like to limit a user as much as possible and give him only
actions that he needs with his VM. If we disallow a user the right in
system|configure system|manipulate permissions), we give the user, in
user portal, only basic mode. But then three is no option to attach a cd
in the basic user portal. In basic mode user interface there is no
chance in attaching a cd (as this is a basic operation a solution to
this would be a button attaching a cd when starting a vm).
If we allow the user to manipulate permissions, we get the extended menu
back and the user is limited, but we found unacceptable when he is
adding permission to the VM, he sees all the users (name, surname,
email!) in the ovirt authentication mechanism? A solution to this would
be authenticating to the directory service as a user an not as ovirt
admin user - meaning that the user will see only users that we allowed
he sees in the ldap directory.
Thank you.
Best Regards,
Andrej

[Engine-devel] [ANN] Development environment and Gentoo packaging (preview)
by Alon Bar-Lev
Hello All,
We[1] are working to rewrite the current installer to something more portable and flexible.
Currently two milestones had been reached:
1. Ability to install almost fully functioning ovirt-engine at $HOME for development environment.
2. Porting ovirt-engine to run on different distribution, Gentoo.
We will be glad to receive feedback on either.
Code is located at github[2] for now, at otopi branch.
Instructions for setting up development environment are available[3].
Gentoo overlay for live ebuilds is available[4], the following packages are valid:
- app-emulation/otopi
- app-emulation/ovirt-host-deploy
- app-emulation/ovirt-jboss-bin
- app-emulation/ovirt-engine
Why Gentoo first? because source based distributions demands the highest level of customization, solving the complex issue ease to continue porting to binary based distributions.
Please remember that this is work in progress, and not guarantee to be stable or even work... The installer was re-written from scratch so expect issues at this point.
Any feedback is welcomed, we are focusing first in providing the functionality of the existing installer to be able to replace it entirely before going into new adventures.
Regards,
Alon Bar-Lev.

[Engine-devel] spice-xpi(firefox) plugin for Windows
by Christophe Fergeau
--tsOsTdHNUZQcU9Ye
Content-Type: text/plain; charset=us-ascii
Content-Disposition: inline
Hi everyone,
Lately I've been hacking on getting the spice-xpi plugin to work on
Windows. This is the Firefox plugin that is used on Linux to implement
the portal SPICE console.
This work has now been merged upstream (
http://cgit.freedesktop.org/spice/spice-xpi/ ), and I've pushed a
scratch build using mingw available from
http://koji.fedoraproject.org/koji/taskinfo?taskID=5265107 (this will go
away in several days). Copying this dll + its dependencies to the
C:\Program Files\Mozilla Firefox\plugins directory are enough to get
a spice-xpi plugin to show up in about:plugins, and to then be able
to start a SPICE client from the spice-xpi test page (
http://teuf.fedorapeople.org/plugins/test.html ).
The dependencies I had to copy are:
gspawn-win32-helper-console.exe
gspawn-win32-helper.exe
iconv.dll
libffi-6.dll
libgcc_s_sjlj-1.dll
libgio-2.0-0.dll
libglib-2.0-0.dll
libgmodule-2.0-0.dll
libgobject-2.0-0.dll
libgthread-2.0-0.dll
libintl-8.dll
libstdc++-6.dll
pthreadGC2.dll
zlib1.dll
(I picked them from the various mingw-* fedora packages).
The reason for this email is that to be usable from oVirt, some portal
changes are needed as it currently only tries to use the spice-xpi plugin
on Linux platforms.
Another fuzzy bit is how to get this plugin to the users' machines...
And that's about all I had to say in that email ;) Let me know if that's
useful to oVirt, how you want to integrate this, ...
Cheers,
Christophe
