Hi All,

I'm wondering if it's possible to PXE boot nodes so we don't need to install every server on local disks.

I have read something in the docs about a Fedora ISO, but how does this work and will it be possible with CentOS ?

Thanks!

Re: Small howto to install ovirt dreyou on Centos 6.4

Itamar Heim — 2013-06-17T14:47:10

mostly for sake of my ignorance - is the dreyou repo maintained with 
patches post the 3.2.1 version which added .el6 support?
if so, why not doing so directly to the 3.2.x stable gerrit branch?

Thanks,

Small howto to install ovirt dreyou on Centos 6.4

Kevin Maziere Aubry — 2013-06-17T14:10:41

Hi

For manager,

   -

   yum install wget
   -

   wget http://www.dreyou.org/ovirt/ovirt-dre.repo -P /etc/yum.repos.d/
   - yum install ovirt-engine


For hypervisor:
selinux and firewall are activated, DO NOT remove them
You must have a working dns between you nodes (if all-in-one it's ok), at
least put nameservers into /etc/hosts (hyp and manger)

   -

   su -c 'rpm -Uvh
   http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
   '
   -

   yum install wget
   -

   wget http://www.dreyou.org/ovirt/ovirt-dre.repo -P /etc/yum.repos.d/
   -

   yum clean all
   -

   yum makecache
   - check that ifcfg-eth0 does not contain NETMASK and PREFIX, remove
   PREFIX if needed
   - yum install vdsm
   - Ovirt node can now be added into the manager
   -

   setsebool -P virt_use_sanlock=on
   - setsebool -P virt_use_nfs=on
   -

   yum install vdsm-hook-qemucmdline vdsm-hook-fileinject vdsm-hook-floppy
   -

   service vdsmd restart

Hope it can help.

Hi Karli,

I apologise that this issue wasn't taken care of yet. It is clear that
the priorities of developers shifted towards work on features in 3.3
release, which feature freeze is happening in about 2 weeks, so you can
understand the time pressure they all have. There's no need to be angry
about that. It is an open source project and as resources for the
development are limited, we're trying to do our best to cover as much
issues as possible. This can lead to situations as this issue, which
may be left behind for some time.

I´m not angry, as I stated before, I´m more confused, and maybe a little disappointed that important(in my opinion) pieces of a projects continuum have been ignored like that. I´m having a hard time understanding the reasoning behind the priorities that have made this issue appear. In my mind, making sure that users of any project are able to follow between minor upgrades is a given, with a schedule like; 1) Feature freeze, 2) Fix release blockers (upgrading being one of them), 3) Release, in that order. Now what´s happening is that you are kind of hoping to drag this out until the problem goes away by itself when you decide it´s time to stop supporting 3.1.

That said, the process for upgrading the oVirt 3.1 on Fedora 17 to
oVirt 3.2 on Fedora 18 is complex and non-trivial, that's why it is
taking time to resolve all the issues that come up in the process.

If this matter is not extremely urgent, we are currently working on a
tool that may make this upgrade easier, albeit, maybe, not completely
automatic.

On the other hand, if this is a completely and utterly urgent, we may
try to guide you through possible manual attempts to perform the
upgrade. Mind though, that they weren't thoroughly tested, and not
promised to go smoothly or even work, and we may have to think about
possible alternative solutions on the go.

Straight answer: Am I ever going to be able to upgrade from 3.1 to 3.2?

My concern (fear) is about being left behind, abandoned. It makes me feel non-important. Just like any admin, the work put down to make Templates, to set up quotas, create VMPools, a dozen of guests. And then have to export everything (nullifying the idea of "Thin Provisioning"), redo every Role, reset every permission, quota, and so on, isn´t (in my opinion) viable in the long run for oVirt as a project to demand. That´s why I had the notion that upgrading surely had to be a high priority. Was I wrong about that?

Re: cpu stuck after joining fedora 18 node to ovirt

Pavia Daniele — 2013-06-17T11:41:31

Hi Joop,
thanks for your feedback, the workaround you suggested did the trick. I 
noticed that we've got other ovirt nodes running fine with 
kernel-3.9.4-200.fc18.x86_64 but that does not seem to be present in the 
fedora stable repo. Looks like we were having issues with 
kernel-3.9.5-201.fc18.x86_64.

I owe you one ice-cold beer.

Cheers,
Daniele

it seems that upgrades on .el6 platforms (RHEL/CentOS) are easier (since 
not a major upgrade of the underlying OS)?

inplemented or am I wrong that we have to do this manually.

Thanks again!!

Cheers,

Matt
