removed some "marked" fields from instance type
by Tomas Jelinek
Hi all,
as you may know, a subpart of the instance type entity (the "marked" column from [1]) are the ones which are marked with the chain icon in the VM dialogs.
The meaning is that this fields are so important that if you want the newly created VM to be based on that instance type, you can not change any of this fields.
The problem was that too many of the fields was "marked" which would force the user to create lots of instance types like: "big with soundcard", "big with smardcard and
soundcard", "medium with smardcard and without soundcard" etc. This after some more thinking seems to be an incorrect approach - the list of "marked" fields should be small and contain
only the really most important fields which lets you to categorize the VMs and not all the devices.
I have proposed two patches ([2], [3]) which implement this. According to this patches only the following fields will be "marked":
- memory size
- num of sockets/cores per socket
- HA
- migration model/downtime
- priority
- balloon
- min allocated memory
So the behavior will now be:
- the instance type still contains all kinds of devices we support
- only a small part of them are "marked"
- when the user creates a VM from an instance type, he will be provided by a big set of defaults from the instance type he can tune
- he will also be provided by a small set of fields he can not change if does not want to be detached from the instance type
Thoughts?

[SCALE][RFC] ksmd bound to one core
by Sven Kieske
Hi,
currently ksmd is a single process
and is thus bound to one core.
This leads to some scaling problems such as:
If you got a lot of vms on one host with huge amounts
of ram you can observe that the cpu usage by ksmd
goes easily to 100%.
I wonder if ksmd could not be split up
in child/worker threads, thus enabling higher density
of vms on one host.
or can this just be tweaked by altering values in
/etc/ksmtuned.conf ?
What do you think?

long type for engine<->vdsm communication
by Piotr Kliczewski
Hi,
Currently we are unable to send long values between engine and vdsm
due to xmlrpc limitation. There is an extension i8 for xmlrpc which
enables 64bit numerical values (long) but we can't use it due to
compatibility reasons. To workaround this limitation people cast long
to string before sending it to the other side. I came up with engine
and vdsm patches [1] to make this type conversion in single place.
Jsonrpc supports long marshalling so by having above patches we can
start to use long types without worrying about type conversion.
Please let me know what do you think about it and whether there are
any reasons why we should not have this changes in 3.6.
Thanks,
Piotr

[QE][ACTION NEEDED] oVirt 3.5.1 RC status
by Sandro Bonazzola
Hi,
We're going to start composing oVirt 3.5.1 RC on *2014-11-25 08:00 UTC* from 3.5 branch.
Maintainers:
- Please be sure that 3.5 snapshot allow to create VMs before *2014-11-24 15:00 UTC*
- Please be sure that no pending patches are going to block the release before *2014-11-24 15:00 UTC*
- If any patch must block the RC release please raise the issue as soon as possible.
A bug tracker [1] has been opened and shows 1 open blocker:
Bug ID Whiteboard Status Summary
1142710 integration NEW Volume creation failed while deploying Hosted Engine on iSCSI
There are still 181 bugs [2] targeted to 3.5.1.
Excluding node and documentation bugs we still have 151 bugs [3] targeted to 3.5.1.
Maintainers / Assignee:
- Please add the bugs to the tracker if you think that 3.5.1 should not be released without them fixed.
- Please update the target to 3.5.2 or later for bugs that won't be in 3.5.1:
it will ease gathering the blocking bugs for next releases.
- Please fill release notes, the page has been created here [4]
Community:
- If you're testing oVirt 3.5 nightly snapshot, please add yourself to the test page [5]

Any info for analyzing Ovirt??
by 이현수
Dear Ovirt
I aminterested in developing VDI using Ovirt.
I need to know how Ovirt works in coding level because I might have to
change or verify the Ovirt code.
So, if you send me any info, such as UML(Unified Model Language),
it would be very thankful.
Hope for your help
Sincerely yours
Hyunsoo Lee.
