this is about current CentOS containing a quite dated version of cloud-init.

as rhel 6.5 GA'd and has these properly, shouldn't be an issue, and

Yes there is lack of documentation in this area, it's a shame but given it's an
open source project with an open wiki, everyone is invited to contribute and
improve this.

I'll see if I can get a page started..

Not sure what you mean by all these "restrictions", from what I know the 
firewall
rules that are set on each host are to allow host to talk to engine
(ssh, vdsm, VM consoles traffic, etc) no more no less..

Usually the default behavior of firewall is to block almost all communication so
when you add a host and check the "Configure firewall" box it modifies it so 
that
your host can function properly.

oVirt has no sense of firewall otherwise. For all it cares you can turn it off
completely, or configure it by yourself (manually or via 
puppet/chef/foreman/etc)
and not use the capability of the system to configure it for you.

You can also change it so that it uses the rules you want by modifying
IPTablesConfig via engine-config tool.

What slaps did you see?
What simple setups don't work?

Your VMs will be sitting on the ovirtmgmt network, or on a VLAN?

If you want to use VLANs for the VM traffic, you can configure the management
network to be non-VM thus allowing you to put VLANs on the same NIC this
network is occupying (just make sure to sync it first, because changes aren't
applied automatically to the hosts, yet).

In my small setup, the VMs are not on VLAN and can talk to all other machines
on the LAN via SSH and I didn't configure anything special on host level..

Odd, All my VMs/Hosts (They also only have one nic) can talk to each 
other and I don't see any rules trying to prevent this in iptables. 
Also, unless there is some feature I don't know about, ovirt doesn't 
screw with VM internals. My ovirtmgt network is the same as my main network.

Re: [Users] backups

2013-11-27 Thread Juan Pablo Lorier 
Hi,

Just curious, is it really the porpoise of the snapshot to backup both
the vm and the application data? I think snapshot is appropriate to
backup the vm and the you should have your regular backup for the app,
as a database backup that can be done online. In this scenario you take
a backup of the vm when something changes (updates, new software,
configs, etc) and not all the time and do regular backups of the db as
it's the information that changes all the time.
I said this because I'm curious about the benefits of doing backups the
way it's been posted.

The main problem in oVirt with this strategy would be the lack of live

Hi, 

we've already solve this issue and it probably be included in the next release.

a simple workaround:

either disable ballooning in the cluster (edit cluster -> Optimization -> 
uncheck Enable balloon)
or enable ballooning for the vm (edit vm -> Resource Allocation -> check Memory 
Balloon Device Enabled)

Thanks, Gilad.

Yes, for example for MySQL, you could

1. issue a FLUSH TABLES WITH READ LOCK statement
2. create a snapshot
3. issue a UNLOCK TABLES statement

before starting a backup from the snapshot, to get a consistent backup
of the binary table space.

The work-around for this is to SSH into the guest first, put the

[Users] oVirt PPC status update

2013-11-27 Thread Sandro Bonazzola 
Hi,
anybody can report about PPC status for 3.3.2 and 3.4.0 target releases?
It would be nice having someone for PPC at ovirt-sync meeting from next week 
on, so please join :-)

this is about current CentOS containing a quite dated version of cloud-init.

Re: [Users] Big issue with oVirt

2013-11-27 Thread Martin Sivak 
Hi,

this was indeed a bug in our code. It happened when ballooning was enabled 
(Cluster / Optimization), but no balloon device was configured (Vm / Resource 
Allocation).

This is fixed by http://gerrit.ovirt.org/#/c/21783/ and tracked by 
https://bugzilla.redhat.com/show_bug.cgi?id=1035297.

We will merge it to master momentarily and then update the released version as 
well. Thanks for the report.

I run it in libvirt/kvm on a separate machine. I use RH6 in the engine 
VM, and F19 on the i5 libvirt host (and RH6 on my i7 host/node).


It might be interesting to run a survey to find out what OS people are 
using for Engine and Host. But it's not worth a survey on its own - I'm 
sure there are lots of things that would be useful for the Community to 
know and I'm not a good person (yet) to put together a comprehensive survey.


I have found an enormous difference in performance when using SSD on my 
i5 - it totally outperforms my i7 (no SSD), and am considering springing 
for a 512GB drive on my host/node. I'd also like to see some writeup on 
performance tradeoffs of different platform architectures.

If you're going to use shared storage I think you may be interested in hosted 
engine feature.
Take a look at: http://www.ovirt.org/Features/Self_Hosted_Engine and 
http://www.ovirt.org/Hosted_Engine_Howto
(actually you'll need nightly repository for testing it)

[Users] oVirt Node 3.0.3-1 for oVirt 3.3 release

2013-11-27 Thread Fabian Deutsch 
Hello,

finally also oVirt Node images for oVirt 3.3.1 are available.

The latest ISO can be downloaded here:
http://resources.ovirt.org/releases/3.3/iso/

To get started take a look at the section in the Quick Start Guide:
http://www.ovirt.org/Quick_Start_Guide#Install_oVirt_Node

oVirt Node is a small image with yet enough software for bare metal
hosts which shall be managed by oVirt Engine. It is easy to handle and
can be deployed using CD/DVD, PXE/Foreman and USB.

I reported this:

 As for the current cluster config:
 - optimization : none (disable memory page sharing)
 memory balloon optimization is not checked

 - resilience policy : migrate virtual machines

 - cluster policy : none

Can I safely install ksm on f19 and then enable and test?

Actually, looking at the spec file. The user is added with the -o

problem should go away and was probably the original intent of the 
spec file writer.

Actually, looking at the spec file. The user is added with the -o 
option (Allow non-unique). If you added -o to groupadd then the 
problem should go away and was probably the original intent of the 
spec file writer.


getent group ovirtagent >/dev/null || groupadd -r -g 175 ovirtagent
to
getent group ovirtagent >/dev/null || groupadd -r -g 175 -o ovirtagent
https://admin.fedoraproject.org/updates/ovirt-guest-agent-1.0.8-6.el5 
contains this fix.

In my case, at least for the host selection on boot problem, I already
powered off all the infra but didn't solve...

can you provide more of the engine log?

[Users] Live migration

2013-11-27 Thread Neil Schulz 

Hello,

We are in the process of testing oVirt and replacing citrix all together.

A few things we are curious about but can't find any concrete 
information on:


Can oVirt live migrate data (VM's, etc.) to another machine in the 
pool/cluster in the event of a hardware failure, if the data is stored 
locally on the machine? For this to be possible, does it have to be on a 
shared storage?


Thank you,
Neil

Re: [Users] backups

Thank you for this hint, I didn't know about GhettoVCB and I'm
definately going to have a look at it.

The problem with snapshot-based backups is, that they are usually only
crash-consistent, meaning that they contain the state of a system's
disks as they would be if you pulled the power plug on a server. If you
restore a system from this type of backup, you would see file system
recovery happening at the first boot, and you risk data loss from -for
example- database servers.

The process that GhettoVCB uses according to your description above is
the same. Your backups are only crash-consistent.

If you need application-level consistency, you need a mechanism to
inform applications that a backup is going to take place (or rather: a
snapshot will be taken) and that they should place themselves in a
consistent state. For example: sync data to disk, flush transaction
logs, stuff like that. Microsoft Windows has VSS for that. For Linux,
there is no such thing (that I know of). Common practice for "quiescing"
database servers and such on Linux is making consistent SQL dumps in a
pre-backup job.

I my case, for most guests a crash-consistent backup, containing a
recent MySQL or PostgreSQL dump is sufficient. I use LVM snapshots (not
oVirt snapshots) for backups, and I use Rsync to transfer the data. I
have been experimenting with Virtsync [1], but I'm having a bit of
trouble with that, so for the moment, it's just Rsync.

Efficiently backing up sparse images with Rsync can be a bit of a
challenge (that's why Virtsync was created in the first place, IIRC),
but using '--sparse' on the inital backup and '--inplace' on subsequent
backups seems to do the trick.

[1] http://www.virtsync.com/

I hope this helps.

Cheers,
Martijn.
