[Users] ovirt nagios plugin email flood on engine upgrade
by 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?
Thanks,
Itamar

[Users] Permission denied on disk image file !!
by Anil Dhingra
Hi Guys
Any know issue why we are not able to start VM due to permission issue on
disk image file .. as per docs ownership should be vdsm:kvm byt not sure
why its showing below
used - both ovirt-node-iso-3.0.1-1.0.1.vdsm.el6 &
ovirt-node-iso-3.0.1-1.0.2.vdsm.el6 same issue [ using NFS Domain ]
VM n0001vdap is down. Exit message: internal error process exited while

As it doesn't allow us o change permissions any alternate way for this ?or
do I need to manually set permissions in *"/etc/libvirt/qemu.conf"*
alos ther is no such *group *with* "96"* .. so from where it picks this
config .
Another question is related to SELINUX config change for below 2 parameters
to recover from error "*internal error Failed to open socket to sanlock
daemon: Permission denied*" I saw some where this is fixed but not sure why
it appears VDSM should take care of this auto
setsebool -P virt_use_sanlock=on
setsebool -P virt_use_nfs=on

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
here is the log:

[Users] Not enough MAC addresses left in MAC Address Pool
by Thomas Scofield
While building a virtual machine we ran into an error "Not enough MAC
addresses left in MAC Address Pool." In the engine log I see this message.
2013-10-26 14:47:16,590 WARN
[org.ovirt.engine.core.bll.network.vm.AddVmInterfaceCommand] (ajp--127.0.0.
1-8702-12) [6fc05fa4] CanDoAction of action AddVmInterface failed.
Reasons:VAR__TYPE__INTERFACE,VAR__ACTI
ON__ADD,MAC_POOL_NOT_ENOUGH_MAC_ADDRESSES
2013-10-26 14:47:16,591 ERROR
[org.ovirt.engine.api.restapi.resource.AbstractBackendResource] (ajp--127.0
.0.1-8702-12) Operation Failed: [Not enough MAC addresses left in MAC
Address Pool.]
This led me to look at the engine config where I see these
MacPoolRanges: 00:1A:4A:97:5E:00-00:1A:4A:97:5E:FF version: general
MaxMacsCountInPool: 100000 version: general
The MacPoolRange would seem to be the limiting factor here, cutting us off
at 256 MAC addresses, which happens to be the number of virtual machine we
currently have. I assume that updating the MacPoolRange and restarting the
engine would resolve this issue. Has anybody experienced this issue? Why
would the pool size have 256 and the Max entry be set to 100000, that seems
like a large difference.

[Users] so, what do you want next in oVirt?
by Itamar Heim
earlier in the year we did a survey for feature requests / improvements
/ etc.
since a lot of things were added, and priorities usually change, I'd
like to ask again for "what do you need the most from oVirt / what are
your pain points" next?
below[1] I've listed my understanding of what already went in from
previous survey requests (to various degrees of coverage).
Thanks,
Itamar
[1] from the top 12
V Allow disk resize
V Integrate Nagios/Zabbix monitoring - via a ui plugin
V Highly Available engine - via hosted engine[2]
V Open vSwitch integration - via neutron integration
X Allow cloning VMs without template
? Enable hypervisor upgrade/updates through engine[3]
V Allow engine on an oVirt hosted VM - via hosted engine[2]
V Enable guest configuration (root password, SSH keys, network) via
guest agent in engine - via cloud-init
X Integrate v2v into engine
? Bond/extend ovirtmgmt with a second network for HA/increased
bandwidth[4]
X Integrate scheduling of snapshots and VM export for backups in
engine[5]
V Spice – support Google Chrome - via mime based launch
Other items mentioned in previous survey which should be covered by now:
- Fix timeout when adding local host during all-in-one configuration
- Fix engine set-up when SELinux is disabled
- Provide packages for el6 (CentOS, Red Hat Enterprise Linux)
- Allow multiple VMs to be deployed from the same template at the same
time
- ISO domains on local/GlusterS
- Show IP addresses in Virtual Machines->Network Interfaces
- OpenStack Quantum support (now called Neutron)
- noVNC support
- Support spice.html5 and websocket proxy
- Add other guest OSes to list
- Port oVirt guest agent to Ubuntu[6]
- SLA - Allow resource time-sharing
- Spice - Mac client (via mime based launch)
- Spice - port XPI plug-in to Windows (not sure this will happen, but
mime based launch allows using firefox now)
- Spice - client for Ubuntu/Debian (should be covered via mime based
launch)
[2] hosted engine is in active development, but not released yet.
[3] host update is supported, but not for general yum update.
[4] a lot of improvements were done in this space, but i'm not sure if
they cover this exact use case
[5] backup api is now being pushed to master, and orchestration of
backups should probably happen via 3rd part backup vendors?
[6] I'm not sure packaging exists yet, but ubuntu is covered for the
basic functionality of the guest agent.

[Users] Docker -- self-sufficient application containers
by Greg Sheremeta
I haven't looked into this very much, but it sounds promising. Anyone on list familiar with it?
http://www.docker.io/ "Docker is an open-source project to easily create lightweight, portable, self-sufficient containers from any application. The same container that a developer builds and tests on a laptop can run at scale, in production, on VMs, bare metal, OpenStack clusters, public clouds and more."
I wonder if there's interest in shipping oVirt docker containers.

It is, in essence, LXC containers combined with an overlay filesystem.
It's basic PaaS with a Go binary ("docker") wrapped around LXC. It's
neat in the same sense as Vagrant -- you can ship a Dockerfile which can
reproduce your environment very easily, and the Docker team itself has
wrapped all the images in a git repository you can easily branch
from/etc. That said, Docker support won't land in Fedora until F20, and
CentOS around the same time (officially).
I'll admit that I don't get the hype around Docker, since it doesn't do
anything that LXC doesn't already do, but the templating and a
user-friendly binary is nice.
I wonder if there's interest in shipping oVirt docker containers.
I'm interested in Docker to ease the process of building Node images, at
least. oVirt Docker containers would be interesting, assuming LXC
support isn't painful, since the CoreOS (where Docker originated) also
relies on an image with readonly root and overlays on top, so there's
some overlap.
