[Engine-devel] SSH Soft Fencing
by Martin Perina
Hi,
SSH Soft Fencing is a new feature for 3.3 and it tries to restart VDSM
using SSH connection on non responsive hosts prior to real fencing.
More info can be found at
http://www.ovirt.org/Automatic_Fencing#Automatic_Fencing_in_oVirt_3.3
In current SSH Soft Fencing implementation the restart VDSM using SSH
command is part of standard fencing implementation in
VdsNotRespondingTreatmentCommand. But this command is executed only
if a host has a valid PM configuration. If host doesn't have a valid
PM configuration, the execution of the command is disabled and host
state is change to Non Responsive.
So my question are:
1) Should SSH Soft Fencing be executed on hosts without valid PM
configuration?
2) Should VDSM restart using SSH command be reimplemented
as standalone command to be usable also in other parts of engine?
If 1) is true, I think it will have to be done anyway.

[Engine-devel] VNIC profiles
by Livnat Peer
Hi,
We are working on adding VNIC profiles as part of the work to add VNIC QoS.
http://www.ovirt.org/Features/Network_QoS#VNIC_Profiles
We need to define some of the system behavior followed by this change,
here is my take -
Editing a profile -
--------------------
A user should be able to edit the profile properties (including profile
name) while VMs are attached and are using this Profile (reference
should be done by id).
Changing the network though is a bit more tricky as long as we don't
have a way to distinguish between running and current configurations I
think it could be very confusing to the user. Especially since we
support dynamic wiring so the behavior IMO is unpredictable.
I think it should be blocked at this point.
Edit a VNIC / change a VNIC profile -
------------------------------------
Changing the profile a VM is using while the VM is running should behave
like dynamic wiring (changing the VM network while it is running).
Remove a Profile -
-------------------
Is only valid if all VMs that are using this profile are in status down.
It should update all VMs to point to no profile which should behave like
none network today.
I see no reason to support a profile on a none network at this point.
The above is also relevant for upgrade flow (upgrading none network to
point to no profile)
Removing a Network -
----------------------
should remove all profiles on that network
VM snapshot/import/export -
--------------------------
We should handle VMs that are pointing to a network directly for b/w
compatibility.
we need to select first profile that is on that network that the user
has permissions on.
I assume there are more, comments are welcome
Thanks, Livnat

[Engine-devel] Sorting in tabs
by Lior Vernia
Hello everyone (UI peeps in particular),
I've pushed (not yet merged) a patch that would enable us to keep items
in tabs (main/sub) sorted at all times by setting a comparator in
SearchableListModel:
http://gerrit.ovirt.org/#/c/15846/
If a comparator isn't set, then everything should behave as before. If a
comparator is set, then from that moment on the tab items will be kept
in a SortedSet, so that even if an item is added in a way that doesn't
trigger an event (e.g. getItems().add()) the items will be kept sorted
according to the given comparator. If the comparator is set to null,
from that moment on the tab should revert to its old behaviour.
You're most welcome to have a look and let me know if this might break
something (remember though that it's not obligatory to set a comparator,
so only possible breakage should be in generic flows).
Feel free to use it once it's merged; along with SortedListModel, this
should make sorting less painful. Just keep in mind that once you set a
comparator, you can't cast getItems() to a List. This shouldn't be a
problem in general, as mostly it's as useful (and probably more correct)
to cast to a Collection.
Lior.

[Engine-devel] Guid improvements
by Allon Mureinik
Hi all,
I just merged a couple of improvements to the [N]Guid class [1] to improve it's performance both CPU-wise and memory-wise, based on a set of benchmarks presented by Liran.
What this patchset achieves:
1. Clean up the code, so it's easier to understand and use
2. Eliminate the inflation in the memory foot print caused by the getValue() method
3. Eliminate all the heavy calls to UUID.fromString when creating a new/empty Guid instance as a default value
4. Note that the cleanups proposed in (1) will have minor performance benefits (e.g., eliminating useless conditional statements), but I doubt this would be anything to write home about.
>From a developer's perspective, here's what changed:
1. No more NGuid, just Guid. Both static methods to create a Guid from String still exist, and are named createGuidFromString and createGuidFromStringDefaultEmpty.
2. [N]Guid.getValue() was removed, it's no longer needed after (1) was implemented
3. The Guid() constructor was made private, as it forced a redundant call to UUID.fromString(String). If you need an empty Guid instance, just use Guid.Empty
4. The Guid.EMPTY_GUID_VALUE string constant was removed, as it was used for redundant calls to UUID.fromString. If you really, REALLY, need it, just call Guid.Empty.getValue() for a UUID or Guid.Empty.toString() for a String.
5. All sorts of ways to transform Strings to Guids were removed. If you have a literal you trust, just use new Guid(String). If you suspect it may be null, use Guid.createGuidFromString[DefaultEmpty]
6. NewGuid is now called newGuid. We're in Java, not C# :-)
Many thanks to everyone who reviewed this patchset.
You guys rock!
Regards,
Allon

does anyone faced this with new 'development installation'?

[WARNING] engine-setup-2 is a technical preview, and yet to include all functionality that exists in legacy engine-setup. Specifically, engine-setup-2 does not support
upgrade from previous installations.
