[ovirt-users] VM Guest Video size

[Sandvik Agustin]

Hi users,


 Good Day, I'm using Ovirt 3.5 on my Centos 6.6, I'm wondering if
there's a way to increase the size of the vm guest video memory?

TIA

Re: [ovirt-users] oVirt node, hosted-engine, oVirt appliance and cloud-init

[Tolik Litovsky]

Hi

First of all I think cloud-init is optional so user can select if use it or not.
So if somebody wants to deploy hosted engine the hard way by installing it on 
OS , its his choice allowed too.
For our appliance I dont think we need anything except for root password.
Last option is in case somebody have some complicated net config he needs to 
implement in the engine VM on the first run 
we should allow him the option to provide the cloud-init iso by himself and he 
can define all he wants there.

Tolik.

[ovirt-users] CTDB error

[RASTELLI Alessandro]

Hi,
I get this error on node #3 while trying to add it to CTDB cluster.

2015/03/13 17:30:41.706522 [ 4280]: ctdb error: Failed to load nlist 
'/etc/ctdb/nodes'
2015/03/13 17:30:41.706589 [ 4280]: ctdb_set_nlist failed - Failed to load 
nlist '/etc/ctdb/nodes'

config files are the same as the other two nodes, where CTDB service is running 
fine.

What should I check?

Thank you

well, hosted engine complicates things as you'd need to be able to see the 
status of the engine guest
running a standalone engine installation or at least running that hosted engine 
on a single node without any other VM may help….

[ovirt-users] New VMs don't have network connection

[mots]

Hello,

New VMs can't access the network anymore, there's no ethernet device. This 
happens both when generating a new VM from a saved template and when installing 
a new VM with the blank template.
It still works fine with all older VMs, they work properly even after a 
restart. This happens on both of my nodes.

What could be causing this?

I just opened a BZ on it (since it isn't just me):

https://bugzilla.redhat.com/show_bug.cgi?id=1201779

My cluster went a couple of days without hitting this (as soon as I
posted to the list of course), but then it happened several times
overnight.  Interestingly, one error logged was communicating with the
node currently running my hosted engine.  That should rule out external
network (e.g. switch and such) issues, as those packets should not have
left the physical box.

There's already an open BZ:

I'm not sure if that is exactly the same problem I'm seeing or not; my
vdsm process seems to be growing faster (RSS grew 952K in a 5 minute

Re: [ovirt-users] Communication errors between engine and nodes?

[Roel de Rooy]

We are observing the same thing with our oVirt environment.
At random moments (could be a couple of times a day , once a day or even once 
every couple of days), we receive the "VDSNetworkException" message on one of 
our nodes.
Haven't seen the "heartbeat exceeded" message, but could be that I overlooked 
it within our logs.
At some rare occasions, we also do see "Host cannot access the Storage 
Domain(s)  attached to the Data Center", within the GUI.

VM's will continue to run normally and most of the times the nodes will be in 
"UP" state again within the same minute.

Will still haven't found the root cause of this issue.
Our engine is CentOS 6.6 based and it's happing with both Centos 6 and Fedora 
20 nodes.
We are using a LCAP bond of 1Gbit ports for our management network.

As we didn't see any reports about this before, we are currently looking if 
something network related is causing this.

Okay, thanks.

No idea.  It seemed to happen on node5 a bunch over a week, but then there were 
errors on other nodes as well.  It isn't always "Heartbeet exceeded", sometimes 
it is "VDSNetworkException: Message timeout which can be caused by 
communication issues".  I haven't been able to find any network issues that 
could cause this (no errors logged anywhere).

There doesn't seem to be any pattern to when it happens either.  The log entry 
I posted was from 04:42 local time, and a bunch of the VMs are CentOS 5, which 
does log rotation at 04:00 by default (which can spike the CPU and disk I/O), 
but they are all done long before 04:42.  It happened in the middle of the 
afternoon a couple of days ago, while I was logged-in to the web UI, and I 
didn't notice any unusual behavior.

One other odd thing: I have also been experiencing an issue where I randomly 
get logged out of the web UI.  Usually nothing else was going on, but a couple 
of times it seemed to correspond with one of the node errors (hard to tell).  
It looked like the same error as BZ 1198493 (I'd see a bunch of "Failed to log 
User null@N/A out" messages).  I don't know if these issues are related or that 
was just coincidence.

To try to rule out any unseen network issues, I started an fping to all seven 
nodes and the engine from another physical system on the same VLAN.  It is 
sending one ping to each of the eight hosts every 0.2 seconds.  That has not 
shown a dropped packet since I started yesterday afternoon.  However, during 
that time, I also have not seen any engine/vdsm timeouts.  I was going to say I 
had not been logged out of the web UI, but that just happened while I was 
typing the previous sentence.

Nothing will get fixed if no one bothers to
open BZs and send relevants log files to help

Re: [ovirt-users] [Gluster-users] Gluster services won't start any more

Hi,
I've reconstructed the glusterd.info file and the peer files, that solved the 
issue.
Next time it happens, I'll collect the glusterd log that filled up the 
filesystem for further analysis.
Thank you

The above message indicates that /var/lib/glusterd/glusterd.info file, carrying 
the identify (UUID) of the node and the operating version of the glusterd 
binary, was empty.
This _shouldn't_ happen. We need to check for messages in glusterd log around 
the time /var/ filesystem was full to understand why this happened.

As part of the 'init' process, glusterd resolves identities of daemons that 
need to be spawned as part of hosting volumes. The resolution would fail if the 
identity of this node changes between a stop and start of glusterd service.
Glusterd wouldn't start until the point this inconsistency is resolved.

To get out of this situation, we need to reconstruct the configuration files 
that are 'out of date' with respect to the cluster. This could be tedious but 
possible if other nodes didn't have their /var filesystem getting filled.
Each glusterd maintains its copy of volume and peer configuration under 
/var/lib/glusterd.

* /var/lib/glusterd/peers - Holds one file for every peer, excluding 'self'.
  This implies that with the help of remaining nodes in the cluster, we can 
determine this
  node's identity. This means we can reconstruct 
/var/lib/glusterd/glusterd.info on this
  node.

For other files under /var/lib/glusterd that are empty, we could use the fact 
that each node has a copy of the configuration and it can be used to 
reconstruct.

Hope that helps,
kp
