[Users] paid installation and support

[Dimitris Visualweb]

Hello, I am having a small hosting business and I am seeking an experienced
admin for setting up a 2 node HA cluster with oVirt, as described here
http://www.ovirt.org/Features/DRBD/solution_for_2_nodes

 

Thanks in advance

[Users] oVirt Updates - Special KVM Forum/oVirt edition

[Itamar Heim]

A great week at linuxcon/cloudopen/kvmforum/ovirt conference at 
Edinburgh, and some other nice feedback on oVirt, meriting a special 
edition of this update.

Feel free to chime in with your feedback as well.

It is sometimes hard to remember we only released oVirt 3.0 last year, 
and that it takes time to get traction.
For example, see slide 3 in the presentation i gave on oVirt Updates[1] 
to see the clear trend in adoption (via total users mailing list addresses).


Similarly, in Livnat's oVirt-intro session at CloudOpen, with ~75 people 
in the room, almost all raised their hand on her question "who knows/has 
oVirt".


We had a plethora of topics (same link as [1]), but i wanted to highlight:

SUSE support
During Livnat's talk, a question was raised wrt SUSE support.
Asking for more details, we got ~"I'm running oVirt in testing and RHEV 
in production. with 200 SUSE 10/11 servers. I just want the guest-agent 
to have their ip address in the gui".

So first of all, good to know SUSE runs as a guest without issues.
Also, the guest-agent itself is just a python script that should just 
work. Just some packaging is required, so we're looking to revamp this 
in build.opensuse.org, and hope some SUSE users will help us with 
closing and testing this one.


In related SUSE news, I just saw this posted "After looking into oVirt 
it looks absolutely fantastic. Might look into seeing if I can help with 
porting this to openSUSE. What kind of work is involved in the porting 
of the application like this?"

(discussion ongoing)

on PPC:
Leonardo from the Eldorado research center in Brazil gave a lecture on 
their work to add PPC support to oVirt. Paul Mackerras (KVM PPC 
developer) from IBM and Alexenader Graf attended and gave a lot of 
feedback, and potential interest from other PPC vendors, which should be 
hopefully mostly config level changes.


User Stories:
Keele university presented their path to oVirt. Always nice to hear how 
our project is used, and we actually asked them a lot of questions on 
why/how they use it the way they do. They also did a case study with 
Dave Neary, which i hope to see more from oVirt community members.


Also, always nice to hear: in an irc chat on #ovirt: "I looked at ovirt 
about 4 months ago and when I came back a few days ago I was blown away 
at how far it had come! The devs have done an awesome job".


All KVM Forum/oVirt sessions slides (and youtube's) should be available 
here[1]


Thanks,
   Itamar

Thanks for this info!

Then we'll probably need another patch to make this happen.

[Users] ovirt nagios plugin email flood on engine upgrade

[Itamar Heim]

Hi René,

a question - when we upgrade the engine, we move the service to down.
at that point, nagios is sending lots of emails on each failing 
monitored resource due to inability to connect to the API.


Is thee a way to report this "once" per the root cause for all monitored 
resources?

if you have everything in the db, its easier to not clean install, since 
we're still missing an easy "import data domain".

what is the status of your hosts?
can you share engine logs?

Re: [Users] GlusterFS on oVirt node

[Saša Friedrich]

Progress report:

I remounted fs on oVirt nodes rw, started glusterd with no errors.
Then I activated hosts in oVirt Engine. Also no errors! Yei!

Then I created volume (replication), added two bricks (oVirt nodes), and 
started volume. Seems fine. I checkd on node1:


# gluster volume info

Volume Name: data_vol
Type: Replicate
Volume ID: a1cdc762-2198-47e2-9b4a-58fd0571b269
Status: Started
Number of Bricks: 1 x 2 = 2
Transport-type: tcp
Bricks:
Brick1: 192.168.254.124:/data/gluster
Brick2: 192.168.254.141:/data/gluster
Options Reconfigured:
storage.owner-gid: 36
storage.owner-uid: 36
auth.allow: *
user.cifs: on
nfs.disable: off



WORKING!


BUT...  Now i can not create storage domain. When I hit OK button on 
"New storage domain dialog", process is running very long. Eventually 
this process stops and returns " Error while executing action Add 
Storage Connection: Network error during communication with the Host".


I'm stuck again :-( in need for HELP!


tnx

Hello!

Acording to http://www.ovirt.org/Node_Glusterfs_Support glusterfs on
ovirt node should be supported. But I have some difficulties to
implement it.


I installed ovirt (nested kvm - home testing) following "Up and Running
with oVirt 3.3) using Fedora19
Install went well. Everything is working fine.

Now I created two hosts (nested kvm - ovirt node fc19 - just for
testing) and added them in oVirt.
Super fine - working!

Now I'd like to use this hosts as glustefs nodes too. Acording to google
(I'm googling for two days now) I'ts possible, but I can not find any
usable how-to

1. I removed these two hosts from default data center
2. I created new data center (type: GlusterFS)
3. I created new cluster (Enable Gluster Service checked)
4. I added host
5. Now I get error message in events: "Could not find gluster uuid of
server host1 on Cluster Cluster1."


If I ssh to my host (fc19 node) glusterd.service is not running. If I
try to run it It returns error

I reinstalled node and remounter / rw then I checked fs before 
activating host (in oVirt Engine) and after (which files have been

any way I can change node so this directory would be mounted rw? And to 
persist this setting after reboot.

Yey! :)
Yes, mount -oremount,rw make's the FS temporarily writeable. But you
will have issues as soon as you reboot.
We'll need to investigate which paths need to be persisted (so the data
written to them survives a reboot) and which only need to be write-able
e.g. for temporary data.

Would you mind opening a bug for this?

Then I created volume (replication), added two bricks (oVirt nodes),
and started volume. Seems fine. I checkd on node1:

# gluster volume info
  
Volume Name: data_vol

Type: Replicate

Options Reconfigured:

storage.owner-uid: 36
auth.allow: *
user.cifs: on
nfs.disable: off



WORKING!


BUT...  Now i can not create storage domain. When I hit OK button on
"New storage domain dialog", process is running very long. Eventually
this process stops and returns " Error while executing action Add
Storage Connection: Network error during communication with the
Host".

I'm stuck again :-( in need for HELP!

Could you please provide the logfiles mentioned here:

Hello!

Acording to http://www.ovirt.org/Node_Glusterfs_Support glusterfs on

I installed ovirt (nested kvm - home testing) following "Up and Running
with oVirt 3.3) using Fedora19
Install went well. Everything is working fine.

Now I created two hosts (nested kvm - ovirt node fc19 - just for
testing) and added them in oVirt.
Super fine - working!

Now I'd like to use this hosts as glustefs nodes too. Acording to google
(I'm googling for two days now) I'ts possible, but I can not find any
usable how-to

1. I removed these two hosts from default data center
2. I created new data center (type: GlusterFS)
3. I created new cluster (Enable Gluster Service checked)
4. I added host
5. Now I get error message in events: "Could not find gluster uuid of
server host1 on Cluster Cluster1."


If I ssh to my host (fc19 node) glusterd.service is not running. If I
try to run it It returns error

here is the log:

Re: [Users] [node-devel] GlusterFS on oVirt node

[Saša Friedrich]

Thanks, I'll try that (and report). And I think data in that path don't 
need to be persistant, because when I reboot node, and make whole fs rw 
again, host gets attached to oVirt with no errors.


One more thing. Messages log file keep getting me errors (every 2 sec):

Oct 25 08:32:50 localhost python[462]: service-status: 
ServiceNotExistError: Tried all alternatives but failed:
Oct 25 08:32:50 localhost python[462]: ServiceNotExistError:

So I somehow lost hope for node and tried makeing host from fc19 
(minimal installation). Installed, attached host in oVirt engine, but... 
Errors are the same!



Any clue?


tnx

I reinstalled node and remounter / rw then I checked fs before

any way I can change node so this directory would be mounted rw? And to
persist this setting after reboot.

Hey,

do you know if the data in /var/lib/glusterd needs to survive reboots?
If not, then this patch http://gerrit.ovirt.org/20540 will probably fix
the problem. The patch just adds that path to /etc/rwtab.d/ovirt - this
will tell the read-only root to make that path writable at boot.
Due to the nature of Node you will need to build your own image or wait
until the patch lands in an image. Editing the rwtab file by hand at
runtime won't have an effect.

Progress report:

I remounted fs on oVirt nodes rw, started glusterd with no errors.
Then I activated hosts in oVirt Engine. Also no errors! Yei!

Yey! :)
Yes, mount -oremount,rw make's the FS temporarily writeable. But you
will have issues as soon as you reboot.
We'll need to investigate which paths need to be persisted (so the data
written to them survives a reboot) and which only need to be write-able
e.g. for temporary data.

Would you mind opening a bug for this?

Hi Thomas, 

The MacPoolRanges is preset to what range was reserved initially when oVirt was 
being developed. 
Of course, in a LAN this doesn't make much difference as the possibility of MAC 
"hijack" from a hardware vendor is extremely low. 
The 3 first bytes in a MAC specify the vendor ID, and the 3 last bytes the 
"card" address (explained in http://en.wikipedia.org/wiki/MAC_address ), so I'm 
not sure why this was limited to 256 addresses but you can of course change the 
limit. 
I'm guessing it was set not to interfere with addresses used by libvirt that 
you may have running in the LAN which use the same vendor ID. 

Also please notice you can have multiple ranges separated by comma 
e.g. MacPoolRanges: 
00:1A:4A:97:5E:00-00:1A:4A:97:5E:FF,00:1A:4A:97:5F:00-00:1A:4A:97:5F:FF 

Now the other value, MaxMacsCountInPool simply limits the MAC pool size so if 
you have a pool that is too big the engine won't start. 
So for example if you have pools 
00:1A:4A:97:5E:00-00:1A:4A:97:5E:FF,00:1A:4A:97:5F:00-00:1A:4A:97:5F:FF it's OK 
since there are 256 + 256 = 512 < 10 MACs 
But, if you have pools 
00:1A:4A:00:00:00-00:1A:4A:00:FF:FF,00:1A:4A:01:00:00-00:1A:4A:01:FF:FF it will 
fail since there are 65536 + 65536 = 131072 > 10 MACs 

Hope this helps, 
Mike
