[ovirt-users] Can some one share the use cases for the local storage?
Hi, I would like to understand the local storage purpose. I was wondered are there any production systems using local storage? Or in another way, how to use effectively the local hosts disks? My ovirt purpose is so serve HA-VM LAMPs. Thanks, Arman. ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
Re: [ovirt-users] Issues with oVirt 3.4, centos 6.6 and Gluster

Workaround: Install the package yum-plugin-priorities and set priority=1 in the /etc/yum.repos.d/ovirt-3.4-dependencies.repo, section glusterfs-epel. 2 - If you reboot the host, the service glusterd doesn't start at init, and host becomes non operational. Workaround: Manually set glusterd to start at boot, using for example ntsysv. Did you file bugzillas for these issues? They won't get fixed otherwise. -- Mit freundlichen Grüßen / Regards Sven Kieske Systemadministrator Mittwald CM Service GmbH Co.

For real HA you inevitable need a shared storage solution. You could try to utilize local disks by using gluster ceph or any other software defined storage system. Gluster is the most integrated withing ovirt, but here are some caveats: It's not encouraged to run vms on the hosts which are part of the gluster cluster (but it works, at least this is what you can read on this very ML). It's not supported to run hosted-engine on top of gluster, at least not without a replica count of at least 3.

[ovirt-users] replace ovirt engine host
Hello List, currently i am testing backup and restore of my ovirt engine host. So far the backup and recovery works. Since i have a nfs ISO_DOMAIN i need to remount the nfs mounts on my vdsm hosts/nodes. This is kinda ugly but okay :) However, my storage information seems to go weird. It looks like the ovirt engine gets confused about the current status. Do i have to restart vdsm after replacing the ovirt engine? When i put connect my original ovirt engine again the cluster status is okay... I test this by unplugging the original ovirt engine host network cable and doing a restore on a connrected 2nd machine. So i guess my question is: How do i replace my ovirt engine smoothly in a production enviorment? Thanks, Mario ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

I failed to interpret 'mount point' here. If you are talking about 'gluster' volume server , the VM behaviour depends on the gluster configuration which indirectly depend on the quorum configuration and volume configuration. If there is an error from underlying storage ( here gluster volume) VM can pause , however latest versions of ovirt support auto resume.

If you are using local data center the VM migration can't happen. You have to configure a storage domain which can be accessed from your Ovirt Cluster Hosts .

The exception is Error: 'list' object has no attribute 'export' (I tried to specify those files as a list - files=[vm_file1,vm_file2]). Thanks for any help.

A multi process daemon would require careful confining (with cgroups). To my understanding the for KSM to really work well is to have many (idle / high mem) guests which are quite similar? I wonder if ksmd could not be split up in child/worker threads, thus enabling higher density of vms on one host. It's likely going to be trickier than you imagine with the added locking that would be required to synchronize the ksmd threads. Actually I was refraining to answer Svens question since I lack some knowledge here. But I guessed synchronization was the reason for the single threadted design. Some serous work needs to be done on KSM do achieve this goal. I was thinking about some map/reduce aglo to do that... OTOH mangeling with mem pages of guests very requires special care. or can this just be tweaked by altering values in /etc/ksmtuned.conf ? I don't think it can. What do you think?

Hi,
if I get this correctly, you'd like to be notified when certain event
happens (VM created/deleted/etc.) and react upon that. I see multiple
possible approaches here:
0, improve Engine extension API (refer to Alon Bar-Lev for details)
- if extensions can be packaged as JARs and these JARs could include
web fragments [1] it would mean the possibility to deploy custom
servlets onto existing Engine instance (in context of webapp that
processes extensions)
- your custom Java servlet could query REST interface (or be
notified
once something happens, but AFAIK we don't have that implemented
yet)
and do whatever logic is needed
- once I asked Alon about ^^ but never got response from him
- IMHO this would be a nice way to deploy custom Java code on Engine
[1] https://blogs.oracle.com/swchan/entry/servlet_3_0_web_fragment
1, improve UI plugin API
- add VirtualMachineDataLoaded event fired upon each refresh of
VM data in UI table (generalization - {Entity}DataLoaded)
- this is similar to existing {Entity}SelectionChange events
relying on changes in the UI table is a bad idea:
(1) potentially missing events:
the UI displays paginated data; if my VMs are sorted by name, and
I have 1000 VMs in my setup, and I just added a VM named z, it will
be added to the last page which is not displayed right now, so I
wouldn't even be aware that something was added.
(2) potentially creating fake events:
changes in the displayed data in the UI can occur due to change in the
Search query; if I have 50 VMs in my setup, and I initially had the
Vms: search query, and now I change it to VMs: name = a*, which
results in displaying only 10 VMs, this may falsely hint on removal
of 40 VMs from the system.
Agreed, that was a bad idea :) UI data is constrained by things like
search query, pagination, sorting etc. Scratch my previous idea.
As mentioned before, notification of relevant events occuring in system
should be the way to go. Either Engine will provide mechanism to notify
other systems (i.e. email notifier) or other system will poll/listen-to
changes in Engine (i.e. via REST API).
Idea for consideration, if every change to oVirt system would be sent
to some event bus, we could easily implement different notification
mechanisms (like websocket in addition to email), and web apps living
in Engine EAR context could also register to that event bus (imagine
WebAdmin servlet that listens for changes and pushes them to clients).
This can/should be done through the notification service,
currently it supports email snmp traps ... but it could be extended (very
easily)
Cool, maybe something we could do in future as part of UX improvement,
i.e. change notification (push changes to client) to drive UI data update,
instead of periodic polling.
2, write UI plugin that uses oVirtJS to periodically check VM events
not sure if this is referring to VM-related events in the code (e.g.
hooking to the click on OK within the New VM / Remove VM dialog,
or hooking to the Success callback of the action response, or
something similar), or to the VM-related Events (i.e. the ones that
are displayed in the GUI within the Events main-tab / bottom section).
If the former: can be done, I assume, though not sure how complex it
would be to implement the infrastructure for that.
If the latter: this will catch actions that were performed either
via the GUI or outside the GUI; in this case, it would probably be
better to use an Engine extension API (solution 0 above) rather
than a UI plugin, since it will be more reliable, will be active
even when the GUI is not in use, etc.
It was meant simply as polling Engine via oVirtJS / REST API.
But then again, any UI plugin-based solution has the drawback that
web GUI must be active (open) in order for plugin to be active.

An example and 'real' use case to Svens answer: The term 'local' might indeed a bit misleading. The posix file system option basically lets you use anything posix compliant. For instance I am using a cluster file system called StorNext in our company - witch is very well suited for use with oVirt. Without POSIX, I could not have used it. You could try to utilize local disks by using gluster ceph or any other software defined storage system. Gluster is the most integrated withing ovirt, but here are some caveats: It's not encouraged to run vms on the hosts which are part of the gluster cluster (but it works, at least this is what you can read on this very ML). It's not supported to run hosted-engine on top of gluster, at least not without a replica count of at least 3. Posix enables usage of GlusterFuseFS. However, it might be the case the replica 3 is only needed when using FuseFS [1], independent from the fact of using Gluster and Compute on the same host.

Good catch, you’re right that should say “On all hosted-engine hosts, edit hosted-engine.conf”. It does not automatically sync the changes between the hosts.

Re: [ovirt-users] Integration of ovirt-engine GUI with the CLI
I got the use case of ovirt.js. But I don't think so it can be used in my case. I have to instead use CGI/php. My aim is to run the command from the rhevm manager bash prompt with dynamic attributes and then returns the success/failure result. E.g `rhevmcommand -lrt -p password ` Rhevmcommand is written in bash script, which internally calls REST api using curl. Password is similar that of rhevm manager database. Now I want something like snip Var result=`rhevmcommand -lrt` in HTML/java/...web UI. -Nikita On 06/11/2014 6:29 pm, Vojtech Szocs vsz...@redhat.com wrote: - Original Message - From: Itamar Heim ih...@redhat.com To: Nikita Kodkani nikita.kodk...@gmail.com Cc: users Users@ovirt.org, Vojtech Szocs vsz...@redhat.com Sent: Wednesday, November 5, 2014 12:37:21 AM Subject: Re: Fwd: [ovirt-users] Integration of ovirt-engine GUI with the CLI On 11/04/2014 01:54 PM, Nikita Kodkani wrote: Hi, To add further...
