Re: [ovirt-devel] Failed to run "make rpm" on VDSM latest master
by Saggi Mizrahi
We have ioprocess in EPEL and brew builds for el6\7, and builds for f19\f20
in bodhi.
There is no such thing as "pushing to stable". In order to be deemed stable
a package has to sit there for 30 days without negative karma or get enough (3)
positive karma.
We have notified on the mailing list that ioprocess is in need for
karma. In any case, you should start getting used to fetching ioprocess
builds from updates-testing when working on the master branch as
we are not going to wait for a month before adding capabilities to VDSM
after adding a feature to ioprocess (or any other external dependency).
There is no reason for VDSM's master branch to only use RPMs from stable
repos. Quite the contrary, the reason that updates-testing exists is so
that consumers of the RPM can test the impending release and make sure it
works before it is delivered to the general public.
Further more, after using a build from updates-testing with VDSM and seeing
that it works it would be most appreciated if you supply give karma
to accelerate the process of getting a released to the stable repo.

Hi,
Due to the recent discussion (http://gerrit.ovirt.org/#/c/28712/), and as part
of the ongoing focus on scalability and performances (http://gerrit.ovirt.org/#/c/17694/ and many others),
I took the chance to do a very quick and dirty bench to see how it really cost
to do XML processing in sampling threads (thanks to Nir for the kickstart!), and,
in general, how much the XML processing costs.
Please find attached the test script and the example XML
(real one made by VDSM master on my RHEL6.5 box).
On my laptop:
$ lscpu
Architecture: x86_64
CPU op-mode(s): 32-bit, 64-bit
Byte Order: Little Endian
CPU(s): 4
On-line CPU(s) list: 0-3
Thread(s) per core: 2
Core(s) per socket: 2
Socket(s): 1
NUMA node(s): 1
Vendor ID: GenuineIntel
CPU family: 6
Model: 58
Model name: Intel(R) Core(TM) i7-3520M CPU @ 2.90GHz
Stepping: 9
CPU MHz: 1359.375
CPU max MHz: 3600.0000
CPU min MHz: 1200.0000
BogoMIPS: 5786.91
Virtualization: VT-x
L1d cache: 32K
L1i cache: 32K
L2 cache: 256K
L3 cache: 4096K
NUMA node0 CPU(s): 0-3
8 GiBs of RAM, running GNOME desktop and the usual development stuff
xmlbench.py linuxvm1.xml MODE 300
MODE is either 'md' (minidom) or 'cet' (cElementTree).
This will run $NUMTHREADS threads fast and loose without synchronization.
We can actually have this behaviour if a customer just mass start VMs.
In general I expect some clustering of the sampling activity, not a nice evenly interleaved
time sequence.
CPU measurement: just opened a terminal and run 'htop' on it.
CPU profile: clustered around the sampling interval. Usage negligible most of time, peak on sampling as shown below
300 VMs
minidom: ~38% CPU
cElementTree: ~5% CPU
500 VMs
minidom: ~48% CPU
cElementTree: ~6% CPU
1000 VMs
python thread error :)
File "/usr/lib64/python2.7/threading.py", line 746, in start
_start_new_thread(self.__bootstrap, ())
thread.error: can't start new thread
I think this is another proof (if we need more of them) that
* we _really need_ to move away from the 1 thread per VM model -> http://gerrit.ovirt.org/#/c/29189/ and friends! Let's fire up the discussion!
* we should move to cElementTree anyway in the near future: faster processing, scales better, nicer API.
It is also a pet peeve of mine, I do have some patches floating but we need still some preparation work in the virt package.

HP ILO2 , fence not working, with SSH port specified, a Bug?
by mad Engineer
hi i have an old HP server with ILO2
on manager i configured power management and configured SSH port to use for
ILO2
for checking SSH i manually ssh to ILO and is working fine,

ssl=no out err *Unable to connect/login to fencing device*
*Manually testing*
fence_ilo -a xxxxxx -l Administrator -p xxxxx -o status
Status: ON
but with ssh port specified ie *-u *
fence_ilo -a xxxxxx -l Administrator -p xxxxx -o status -u 22
*Unable to connect/login to fencing device*
So when we specify ssh port it fails and with out ssh port its working
this is the case with ILO2 also
for ilo3 and ilo4 since it does not ask for SSH port its working
Is this a Bug

Project vdsm-jsonrpc-java backup maintainer
by Sandro Bonazzola
Hi,
looks like only one person has +2 / merge rights on vdsm-jsonrpc-java.
I think every project should have a "backup" maintainer.
Since it seems pkliczewski is the only committer there, I would like to propose him as maintainer too.

Tune HA timing,is it possible
by mad Engineer
Hi,
Is it possible to tune time required to reboot VM in case of host
failures.
in our test we powered off one of the Host.
Manager was still showing both Guest and Host as UP for around 5 minutes
and after that it took another 4-5 minutes to start VM.
Is there any tunable parameter that can be modified to bring down the time
required to recognize Host failures.
Thanks

[QE][ACTION REQUIRED] postponing beta release due to basic sanity test failure
by Sandro Bonazzola
Hi,
while performing basic sanity test on 3.5.0 beta candidate I've seen the following bugs:
Bug 1113882 - [ ERROR ] Failed to execute stage 'Closing up': [ERROR]::oVirt sdk is disconnected from the server.
Bug 1113891 - storage domains are listed twice
Bug 1113898 - New Virtual Machine dialog drop down list are all empty
Bug 1113898 make impossible to create a new VM, so basic sanity test failed.
We need to postpone beta release until this one is fixed.
repoclosure test failed on F19: http://lists.ovirt.org/pipermail/users/2014-June/025475.html
Since candidate beta build failed sanity test, I'm going to rebuild engine from master and repeat sanity test on the new build.

Engine - Changes to various issues around commands and queries construction and internal execution - please read
by Yair Zaslavsky
Hi all,
Thanks to the help of Alon, oved, Tal, Moti, Arik and others, the following changes were introduced:
1. Internal commands invocation -
When invoking an internal command from a command, please use the following :
Instead of Backend.getInstance().runInternalAction...
Use
runInternalAction - a new method that was introdced at CommandBase.
This method has two variants - one that accepts command context, and the other that does not have a command contet -
runInternalAction(VdcActionType,VdcActionParametersBase,CommandContext)
and
runInternalAction(VdcActionType,VdcActionParametersBase)
If CommandContext is not passed the context at the calling command will be cloned and set at the child command.
If a Command context is pased - it should be the responsibility of the caller to clone, however, this will give the caller some degree of freedom to determine whether various
parts of the context will be cloned, or not.
Examples:
runInternalAction(VdcActionType.AddPermission, permissionParams) has the same effect as : runInternlAction(VdcActionType.AddPermissiosn, permissionParams, getContext().clone())
runInternlAction(VdcActionType.AddPermissiosn, permissionParams, getContext().clone().withoutCompensationContext()) - will cause the compensation context to be reset, and let the child command determine the value of compensation context (at handleTransactivity method).
The complete list of "context alteration methods" are -
withCompensationContext(CompensationContext) , withoutCompensationContext()
withLock(EngineLock), withoutLock()
withExecutionContext(ExecutionContext), withoutExecutionContext() - bare in mind that all these follow the chaining method "design pattern" [1] (I would like to thank Moti for the naming suggestions)
two methods for running InternalAction with context for tasks were created:
runInternalActionWithTasksContext(VdcActionType, VdcActionParametersBase)
runInternalActionWithTasksContext(VdcActionType, VdcActionParametersBase, EngineLock)
These methods use ExecutionHandler.createDefaultContextForTasks to create the relevant command context to be passed to the child command.
runInternalMultipleActions was introduced to command base in a similar manner, with 3 versions:
runInternalMultipleActions(VdcActionType, ArrayList<VdcActionParametersBase>)
runInternalMultipleActions(VdcActionType, ArrayList<VdcActionParametersBase>, ExecutionContext)
runInternalMultipleActions(VdcActionType, ArrayList<VdcActionParametersBase>, CommandContext)
2. Queries invocation -
runInternalQuery(VdcQueryType, VdcQueryParametersBase) was introduced to command base.
Basically it takes the engine context from the current command context, and runs the internal query with it.
EngineContext is the context which should hold all the common attributes to our flows at engine - currently it holds the engineSessionId, working towards moving correlationId to it as well.
3. Commands & Queries coding
Each internal query should have a ctor that takes the parameters, and also the engine context .
As some of the queries are both internal and non internal you may have two ctors - one with parameters only, one with parameters and EngineContext
for example
public class GetUnregisteredDiskQuery<P extends GetUnregisteredDiskQueryParameters> extends QueriesCommandBase<P> {
public GetUnregisteredDiskQuery(P parameters) {
this(parameters, null);
}
public GetUnregisteredDiskQuery(P parameters, EngineContext context) {
super(parameters, context);
}
Notice that the ctor without the context calls the one with the context.
Same happens at Commands:
public RemovePermissionCommand(T parameters) {
this(parameters, null);
}
public RemovePermissionCommand(T parameters, CommandContext commandContext) {
super(parameters, commandContext);
}
4. runVdsCommand was introduced to CommandBase as well
runVdsCommand(VDSCommandType, VdsCommandParameters) - currently this just runs the vds command on vds broker, working on propagating the engine context via vds broker as well.
Please use the above in your code. If you see any issues , or places where its problematic to use, feel free to contact me.

Node down,but ovirt still shows VM as up
by mad Engineer
Hi,
I am using Cisco UCS C200 M2 as Host running Centos 6.5 and KVM,
Power Management not working properly,hence even with Node down Ovirt shows
VM as still up,with uptime of VM increasing(on the manager)
if i continue and save the changes its causing problems:
1. HA is not working ( Node status changed to Non responsive but VM status
still up!!
2. Restart of Host gives wrong information-it shows host as rebooting but
actually nothing is happening to Host!!
While configuring power management:
On ovirtmanager edited Power management and chose cisco_ucs with proper
authentication to CIMC,but when clicked on test,it shows
*Test Failed, Failed: You have to enter plug number Please use '-h' for
usage *
What is this plug,i couldn't find anything in CIMC
This can be the reason for failure of HA and restart
Can someone please help me fix this
Thanks

Stats for oVirt Downloads: Jan-May 2014
by Brian Proffitt
All:
For some time, traffic statistics for the sites in the ovirt.org domain (lists, resources, gerrit, and linode01) have been collected and organized using awstats[1] at stats.ovirt.org[2]. From the data provided for resources, I have been able to put together what should be a fairly definitive set of statistics for software downloads within the oVirt Project.
Methodology
The statistics that were analyzed were for five parts of the project:
* Engine
* Live
* Node
* Engine Reports
* Engine dwh
Downloads of the Engine RPM file, it was determined, would be indicative of actual oVirt installs. The allinone RPMs were not analyzed at this time, since installing this RPM is a choice made during the installation process itself. Tracking the Engine Reports and dwh RPMs was done to determine the popularity of these two tools and to ensure their numbers were comparable.
To count downloads, data was gathered each month that listed the total downloads of every file, a number derived from the total hits each file had, minus any 206 hits, which indicated incomplete downloads. Key files for Engine, Engine Reports, and Engine dwh were identified and the data filtered to include counts for each one of the files, in whatever version released.
Tracking of Live and Node RPMs was already set up within the awstats reporting, and was taken directly from awstats in each month.
If there is any part of this methodology that is in error, feedback is very much appreciated.
Presentation of Data
Data was aggregated using Pivot Tables in Google Docs, and the application of SUMIFS functions in the same spreadsheet document. This document is still being formatted into a more presentable form, but until then, I wanted to deliver some preliminary results to the community for the first five months of the year.
It will be noted that in general, download numbers are on the rise, particularly around the time oVirt 3.4 was released. There are significant gaps in downloads of Engine Reports and Engine dwh. I am still investigating the cause of this lack of data.

multipath configuration
by Yeela Kaplan
Hi,
Currently multipath.conf is being rotated each time we reconfigure it.
We'd like to change the behaviour for multipath.conf so that current configuration will be commented out
and we'd stop rotating (in the same manner as libvirt conf works today).
Does anybody have any comment for/ against?
Thanks in advance,
Yeela
