Re: [ovirt-users] Upgrading oVirt-Node-NG from 4.0.3 to 4.0.6

[Fabian Deutsch]

Hey Thomas,

you should be able to run yum update on Node to get it updated to the
latest version.

If this fails, then you can still download the rpm from jenkins (will
need to dig out the url) and the manually yum install the rpm to
update node.

Yes - nmtui or nmcli are the tools you can use here to get your host
hooked up to the network.

 What happened with the TUI ?

 Have just installed a 4.1 oVirt Node and it seems it is CLI only and I
 only see a shell login. Is it correct ?
 I read some pages on ovirt.org saying the old TUI was problematic and it
 was being redesign but that seems old.

 Or do I understand correctly and everything is now handled by Cockpit ?

Re: [ovirt-users] Ovirt Nodes - Which OS

[Fabian Deutsch]

+1 for CentOS

It's currently probably the best tested and most stable platform when
looking at CentOS and Fedora.

Yes, true that you need to do manual partitioning when choosing to use a RAID.

For manual partitioning there are a few constraints which we did not
document yet - patches are welcome!

The constraints are:

- Use thin LVM
- /boot on a separate partition
- /var on a separate LV
- / on a thin LV

This should allow you to perform the installation - If I do not miss anything

So - We did have some problems until Monday where the versions were mixde
up between ovirt-4.0, -pre and -snapshot.
I suppose that this caused the glithc you were seeing, Christian.

I've downloaded
http://jenkins.ovirt.org/job/ovirt-node-ng_ovirt-4.0_build-artifacts-el7-x86_64/lastSuccessfulBuild/artifact/exported-artifacts/ovirt-node-ng-installer-ovirt-4.0-2016083104.iso

and could not reproduce this issue.

Hey Brian,

did you stick to use auto-partitioning when choosing the RAID setup?

This is the URL yuo want - It contains the builds based on the latest
stable release.

Tho I see that it wasn't updated lately.

Nice that the status issue could be solved.

For adding Node, you can either add the host by gpoing to Engine and then
add the host, or you can use vdsm register on the host to register it to
Engine.

Hey Anantha,

please use the latest iso from:
http://resources.ovirt.org/pub/ovirt-3.6-snapshot/iso/ovirt-node-ng-installer-ovirt/

http://resources.ovirt.org/pub/ovirt-3.6-snapshot/iso/ovirt-node-iso/
is our vintage image, and it has known problems with some storage
setups.

Let me know if ovirt-node-ng-installer-ovirtworks for yuo.

[ovirt-users] [ANN] oVirt Node Next Beta

[Fabian Deutsch]

Hey,

the just released oVirt 3.6.6rc1 release marks the first official oVirt release
which is accompanied by oVirt Node Next (Beta).

Since it's pre-alpha release a few weeks ago, Node has seen a lot of testing
and fixes, which brought it to the beta level.

If you have not yet started to test oVirt Node Next, this is the time to do so.
Take a look at the quick-start guide to see the next steps [0].

What is oVirt Node?
oVirt Node is a ready-to-use OS image, containing all the OS and oVirt packages
needed to act as host for oVirt Engine.
The image can be installed in minutes, can be administered using Cockpit [1],
and provides a safe upgrade and rollback mechanism.

Where can I learn more about oVirt Node?
A quick-start guide, and links to additional documentation can be found on the
oVirt Node Project page .

On behalf of the Node team

Heya,

I am not sure if you want to uninstall/remove a node - then you need
to clear the storage - or if you want to reset it - in this case I'd
recommend to reinstall.

[Fabian Deutsch]

Hey,

just a quick heads up that our oVirt Node Next jenkins builds
are currently broken.
Some of the symptoms are that the installation is failing and
that no new updates are available.

We are working on a solution.

This is by design. The idea is that you use the TUI to configure the
initial NIC, all subsequent configuration will be done trough Engine.

This is a valid point - you can not configure Ndoe from the TUI to
connect to more than two networks.

What you can do however is to temporarily setup a route between the
two networks to bootstrap Node. After setup you can use Engine to
configure another nic on Node to access the storage network.

The other option I see is to drop to shell and manually configure the
second NIC by creating an ifcfg file.

Note: In future we plan that you can use Cockpit to configure
networking - this will also allow you to configure multiple NICs.

Hey Christoph,

first thanks for the report.

As Ryan wrote, you need to drop to shell, then all logs are in /var/log.

The problem seems to be an old code fragment which assumes sysV init scripts.
I wonder why we did not encounter it earlier.

Could you file a bug about this issue?

Hey Timothy,

oVirt Node 3.6 is now silently released continuously.
See http://www.ovirt.org/Node for links to the right Jenkins job for
retrieving the latest Node iso.

Hey Kevin.

In the last months we went over to only release oVirt Node through Jenkins [3].

The main reasons is that the Node team was focused on stabilizing
Node, instead of improving the release process.

For the old isos in [1] - We should probably remove them and point to
the continous builds.

I've also updated the links on the main Node landing page:
http://www.ovirt.org/Category:Node

Ah yes, both builds were quite old.

If you want to give it another try, I'd suggest you try out some
builds which are not older than a week, they should be working much
better.

You mean, it should default to the i.e. jenkins url?

Our experience was that it was quite unreliable to pull ~3GB of data
from the internet, thus we recommend to download the OVA and host it
manually.

Could it be that sudo is not configured to operate passwordless?

The strat-up can then fail, because sudo requires a ty, but this isn't

That's a nice idea and we actually actively investigated to use Atomic Host.
Atomic is pretty strong on quickly building and deploying trees. It
also provides the nice features to rollback in case of accidents, and
also has a vibrant community.
But we encountered a few issues i.e. Atomic has tough requirements on
how the root filesystem must look, and how packages can touch/change
the root file-system. Besides that we were seeing issues when it comes
to support a wider range of (multipathed) storage hardware. To just
name two issues.

So for now we don't aim to build Node an the foundations of Atomic.

But we are working on an approach which is similar to Atomic and
allows us to address some long standing issues and make Node much
easier to use, maintain, and customize.

Stay tuned for news on the Node development road-map.

Actually a good point which I also had on my mind.
The main focus of Node will be to host VMs, but having basic container
support to host containers for supporting a feature is surely
something interesting.

This will need work on the vdsm side before it makes sense to pull
this into Node.

Yep, Cockpit will be part of the game on Node.
Kimchi might be problematic - not because of Node - but because of the
way how libvirtd is tuned towards vdsm.
The last time I looked the issue was that libvirtd is not consumable
by kimchi anymore, once vdsm has configured it.
And to me it looks like this does not really fit anyway right now,
because the current assumption is that Engine has the full control
over VMs - and this would be not true anymore if you could use kimchi
to administer your VMs.

Hey Kyle,

on the Node TUI you can only configure one NIC.
Any additional configuration must be done through Engine.

  Hey Patrick,
 
  currently we are not publishing official isos to resources.ovirt.org,
  instead please
  use the ISOs build in our CI:

 Out of curiosity, why is still not 'official' ?

The final bit to do the publishing is just not yet in place.
That final bit will take the ISOs from our CI and publish them, whenever an 
oVirt update is happening.

But in the end, the isos from the CI and the officially released ones, will be 
from the same build process.

Re: [ovirt-users] ovirt-Node + hosted engine question

[Fabian Deutsch]

- Original Message -
 Hi All.
 
 As I was perusing my e-mails from this list earlier today one that
 caught my attention was one that had to do with ovirt-node and hosted
 engine.  It appeared as though it is possible to install hosted engine
 on a ovirt-node host, and indeed, when I installed ovirt-node into a
 VirtualBox VM to poke around, there is a hosted engine option in the
 menu where you can enter a URL for an ISO/pxe source for OS installtion.

Hey,

 I just want to clarify the following questions:
 
   1.) Is it possible to install ovirt-node, and then install a hosted
 engine?

Yes.

   2.) If the answer to 1.) is Yes, does it require some sort of
 NFS-enabled storage, or can you confgiure local storage on ovirt-node
 and install the engine to there?

Currently you can install hosted-engine on eitehr NFS or iSCSI storage

   3.) Is it possible to create NFS-enabled storage on ovirt-node?

No.
Maybe you technically can, but I can just strongly discourage to do that.

   4.) Can you install the hosted engine onto external NFS storage, then
 move/migrate it to local storage on ovirt-node?

I strongly believe not.

 I am thinking of a lab situation where there is only one server, but
 gobs of RAM and storage.  Running ovirt-node as the host would require
 fewer space resources (not that I would necessarily be hurting for
 space, but any extra I could squeeze out would not be unwelcome).

Maybe this will work in future, when we can also configure some storage
server on Node. But for now that is not supported.

  Which one of these ?
  Moreover, reading Fabian statements about bonding limits, today I
  can try
 to switch to a config without bonding.

 vm is a complicated term.

 `brctl show` would not show you a vm connected to a bridge. When
 you
 WOULD see is a vnet888 tap device. The other side of this device is
 held by qemu, which implement the VM.

Ok, understood and found it, vnet2


 I'm asking if the dhcp offer has reached that tap device.

No, the DHCP offer packet do not reach the vnet2 interface, I can see
only DHCP DISCOVER.
   
   Ok, so it seems that we have a problem in the host bridging.
   
   Is it the latest kernel-3.10.0-229.7.2.el7.x86_64 ?
   
   Michael, a DHCP DISCOVER is sent out of a just-booted guest, and OFFER
   returns to the bridge, but is not propagated to the tap device.
   Can you suggest how to debug this further?
  
  Dump packets including the ethernet headers.
  Likely something interfered with them so the eth address is wrong.
  
  Since bonding does this sometimes, this is the most likely culprit.
 
 We've ruled this out already - Roberto reproduces the issue without a
 bond.

To me this looks like either a regression in the host side bridging. But otoh 
it doesn't look
like it's happening always, because otherwise I'd expect more noise around this 
issue.

[Fabian Deutsch]

- Original Message -
 Thanks for answering, my considerations below.

…

  I've observed this behavior in bug
  https://bugzilla.redhat.com/show_bug.cgi?id=1230638
  We also removed all firewall rules, checked iPXE and I also saw the
  requests
  going out, but no replies getting to the VM.
  But here it sounds like it isn't specific to bonds.
  After all I did not find the solution yet.
 
 In our config, I can see the DHCP offer until the hypervisor bridge interface
 toward vm

Just to make sure, is your setup:

NIC -- bridge -- VM?

Or is a bond involved?

 
  It is probably a good idea to install the oS with a static IP, and then
  switch to dhcp to then use tcpdump inside the vm to see what is reaching
  the inside.
 
 Already done. Vm do not acquire the IP address and, on the vm side, tcpdump
 shows only requests.
 At the same time, the DHCP offer s detected on the bridge if of the
 hypervisor.
 
 With static IP, vm works fine.

Yes, it only seems to be around dhcp.

If you don't have a bond involved, then please reopen the bug abaove, and we 
try to find
someone to look at it.

 Hi Dan, guys
 
 Sorry for very late follow-up, but we had a lot of other topics to fix just
 before to go back on this one.
 
 We have tried another approach just to check if the kernel of the vdsm iso
 image used to install the host could create the problem I've reported to the
 list.
 
 Now we have reinstalled the same hardware with latest CentOS 7.1, fully
 updated.
 Installed vdsm, then joined the oVirt cluster.
 
 Well, we are observing the same behavior as before.
 No DHCP offer is reaching the booting VM, and:
 
 brctl showmacs bridge_if show us the booting vm mac-address
 tcpdump -I bridge_if show us the dhcp offer coming from dhcp server.
 
 We have also tried to remove ANY firewall rule.
 
 It isn't a PXE issue (gPXE 0.9.7) but only a DHCP process issue. Infact, if
 we install a vm manually and assign a static IP, it works fine.
 If we switch to dhcp, the vm don't get the dynamic one.
 In this case, tcpdump on vm shows only the DHCP discovery, not the DHCP
 offer.
 
 Any further suggestion/hint ?

Which kernel does the el7 host run? I think that Ido has seen a case
where `brctl showmacs` was not populated with the VM mac, despite a
packet coming out of it.
  
   Kernel is: 3.10.0-123.20.1.el7.x86_64, package is vdsm only. Brctl isn't
  available within vdsm only package.
 
  Could you try upgrading to a more up-to-date

  7/7.1.1503/updates/x86_64/Packages/kernel-3.10.0-
  229.4.2.el7.x86_64.rpm
  ?
 
  bridge-utils is a vdsm dependency. It must exist on your host. Please
  see if the mac of the vNIC shows up on `brctl showmacs` as it should.
 
   
Can you tcpdump and check whether the bridge propogated the DHCP
  offer
to the tap device of the said VM? Does the packet generated by
`ether-wake MAC-of-VM` reach the tap device?
  
   Yes: host see the broadcast :
   0.000.0.0.0   255.255.255.255   DHCP

   It came from the right MAC:

   And it is tagged correctly:
   802.1Q Virtual LAN, PRI: 0, CFI: 0, ID: 3500
  
   This is the offer, on the bond interface:
   1.01235510.155.124.2  10.155.124.246DHCP

   Tagging on the bond:
   802.1Q Virtual LAN, PRI: 0, CFI: 0, ID: 3500
  
   The tag is correctly removed when DHCP offer is forwarded over the
  bond.3500.
   Here's the offer content, seems everything right:
  
   Client IP address: 0.0.0.0 (0.0.0.0)
   Your (client) IP address: 10.155.124.246 (10.155.124.246)

   Nothing of this offer appear on the VM side.

the process is very similar to http://www.ovirt.org/Features/Self_Hosted_Engine

The OVA which is intended for this page can be found here:

Re: [ovirt-users] How do I get discard working?

 oVirt Node - 3.5 - 0.999.201504280931.el7.centos
 
 Using our shared storage via baremetal (stock CentOS 7) - iscsi, I can
 successfully issue fstrim commands. With oVirt at the VM level, even
 with direct LUNS, trim commands are not supported despite having the LVM
 config in the VMs set up to allow it.

Hey,

IIUIC you try to get discard working for VMs? That means that if fstrim is
used inside the VM, that it is getting passed down?

The command line needed for qemu to support discards is:

$ qemu … -drive if=virtio,cache=unsafe,discard,file=disk …

I'm not sure which qemu disk drivers/busses support this, but at least virtio 
does so.
I'm using it for development.

You could try a vdsm hook to modify the qemu command which is called when the 
VM is spawned.

Let me know if you can come up with a hook to realize this!

  Hey Kevin,
  
  can you please tell me the exact Node version you are using?

 Hi Fabian,
 
 I use Node version 3.5 - 0.999.201504280933.el6. I cannot use an el7 version
 now because our nodes are on HP servers and we need the cciss module.

There are a few things we can try:
0. Please provide ps axZ from the running node with the failed libvirtd
   (attach or paste or send to me in private)
   This will help me to see if it's the issue we saw before.
1. The ovirt-node version that is used in your build - to find out if our fix 
is in
2. Try a Node build from today, which should have the fix

 I take it back. This did not solve the issue. I tried batch starting the
 VMs and half the nodes went down due to the same storage issues. VDSM

Is there maybe some IO problem on the iSCSI target side?
IIUIC the problem is some timeout, which could indicate that the target
is overloaded.

But maybe I get something wrong ...

  I've been struggling with oVirt completely falling apart due to storage

  --install-plugin takes a single argument, which is a concatenated list

 Hi Fabian,
 
 I finally succeed to build an image with the two plugins. I needed to use two
 edit-node commands to incorporate the plugins in the ISO.

Hey Kevin,

great that this worked for you.

Tho I wonder why edit-node did not take several plugins at once, it should.

In general it should work when you use Add host from the Engine side.

In that case the certificates should be re-deployed.

Re: [ovirt-users] Hosted Engine on oVirt Node Hypervisor

[Fabian Deutsch]

Hey Jason,

- Original Message -
 I'm setting up some new oVirt infrastructure, and wanted to give hosted
 engine a try.  I downloaded and installed the oVirt Node Hypervisor ISO
 (3.5-0.999.201502231653.el7.centos) on one of 3 nodes.  One of the
 options in the hypervisor menu is Hosted Engine.  This requires an
 Engine ISO/OVA URL for download.  The thing is - as far as I can tell,
 there is no download link for this ISO/OVA on the ovirt release web
 site.  I also can't find anything in the documentation that refers to it
 (or even this menu in the hypervisor). I did find this after some searching:

Yes, you are right, the documentation of Hosted Engine is currently ... sparse.

 http://jenkins.ovirt.org/user/fabiand/my-views/view/Node/job/ovirt-appliance_engine-3.5_master_merged/oVirt-Engine-Appliance-CentOS-x86_64-7-20150319.424.ova

 (Now replaced with a build from 0322).  I asked on the ovirt IRC channel
 and was told that this might work, but because of new functionality
 introduced recently that it also might not. If the feature is available
 in the node ISO, shouldn't there be an appropriate release of the hosted
 engine ISO/OVA that works hand in hand with the node that I've
 downloaded?   If it's not there because it isn't ready, isn't this
 functionality something that should be added to maybe a beta node
 release and tested before being released into the stable node hypervisor
 release?

Yes, the problem here is with the ovirt-appliance.
We did not start building images based on the 3.5 status of the appliance.

I'll see if we can get up a builder for the ovirt-3.5 branch up quickly.

 I asked on the IRC channel whether it might be possible for me to
 kickstart my own engine from the node.  I ran into trouble with that as
 well.   On the installed node, I can only configure one network
 interface.  This is, of course, intended to enable ovirtmgmt for
 communication with engine which would take over and configure everything
 else for you.  Of course, when you don't yet have engine installed and
 need to get it, this leads to a chicken and egg problem.  To kickstart
 engine on node, I need an IP (from mgmt), an image (I guess it could
 come from the mgmt network), but then I also need access to the external
 network (on another NIC) to be able to install the appropriate ovirt yum
 repository, and download the engine!  If I installed my own node
 manually instead if using ISO, I guess I could configure the network,
 and make it work, but I'm trying to take advantage of the work that has
 already been put into node to make this all possible.

I believe I saw a corresponding bug for what you described above.

Does it help if you temporarily add a route to your management network's
router, which enables the hosted-engine host to access the relevant networks
(external, storage, …)?


Greetings
fabian

 Anyway, I'm certainly interested in any feedback from users who have
 been able to make this work.  I guess I could kickstart one node as an
 engine, create the virtual image there, suck the ova down to the mgmt
 server, install node, then use node to re-suck down the hosted engine
 image, but it just seems like a lot of extra work.  Somehow I think it's
 intended to be a little more straightforward than that.
 
 Jason.

  Sure. Once the iscsi target is logged in the call to vdsClient never
  returns. After a few minutes I hit ctrl-c, that's what caused the
  traceback. See below for the output.
  Could you please upload somewhere your VDSM logs (/var/log/vdsm/vdsm.log)?
 
 I have it connecting now. I tested it on another machine again and it
 wasn't working. Changed the MTU back to 1500 on both the SAN and the
 host and now it works fine. Not sure why MTU of 9000 doesn't work, but
 I'll worry about that later.

Maybe some intermediate device can not handle taht jumbo frame?

   Hello,
   on my all-in-one installation @home I had 3.5.0 with F20.
   Today I updated to 3.5.1.
   
   it seems it modified /etc/multipath.conf preventing me from using my
   second
   disk at all...
   
   My system has internal ssd disk (sda) for OS and one local storage domain
   and another disk (sdb) with some partitions (on one of them there is also
   another local storage domain).
   
   At reboot I was put in emergency boot because partitions at sdb disk
   could
   not be mounted (they were busy).
   it took me some time to understand that the problem was due to sdb gone
   managed as multipath device and so busy for partitions to be mounted.
   
   Here you can find how multipath became after update and reboot
   https://drive.google.com/file/d/0BwoPbcrMv8mvS0FkMnNyMTdVTms/view?usp=sharing
   
   No device-mapper-multipath update in yum.log
   
   Also it seems that after changing it, it was then reverted at boot again
   (I
   don't know if the responsible was initrd/dracut or vdsmd) so in the mean
   time the only thing I could do was to make the file immutable with
   
   chattr +i /etc/multipath.conf
  
  The supported method of achieving this is to place # RHEV PRIVATE in
  the second line of your hand-modified multipath.conf
  
  I do not understand why this has happened only after upgrade to 3.5.1 -
  3.5.0's should have reverted you multipath.conf just as well during each
  vdsm startup.
  
  The good thing is that this annoying behavior has been dropped from the
  master branch, so that 3.6 is not going to have it. Vdsm is not to mess
  with other services config file while it is running. The logic moved to
  `vdsm-tool configure`
  
   
   and so I was able to reboot and verify that my partitions on sdb were ok
   and I was able to mount them (for safe I also ran an fsck against them)
   
   Update ran around 19:20 and finished at 19:34
   here the log in gzip format
   https://drive.google.com/file/d/0BwoPbcrMv8mvWjJDTXU1YjRWOFk/view?usp=sharing
   
   Reboot was done around 21:10-21:14
   
   Here my /var/log/messages in gzip format, where you can see latest days.
   https://drive.google.com/file/d/0BwoPbcrMv8mvMm1ldXljd3hZWnM/view?usp=sharing
   
   
   Any suggestion appreciated.
   
   Current multipath.conf (where I also commented out the getuid_callout
   that
   is not used anymore):
   
   [root@tekkaman setup]# cat /etc/multipath.conf
   # RHEV REVISION 1.1
   
   blacklist {
   devnode ^(sda|sdb)[0-9]*
   }
 
 
 I think what happened is:
 
 1. 3.5.1 had new multipath version
 2. So vdsm upgraded the local file
 3. blacklist above was removed
(it should exists in /etc/multipath.bak)
 
 To prevent local changes, you have to mark the file as private
 as Dan suggests.
 
 Seems to be related to the find_multiapth = yes bug:
 https://bugzilla.redhat.com/show_bug.cgi?id=1173290

The symptoms above sound exactly liek this issue.
When find_multipahts is no (the default when the directive is not present)
I sthat all non-blacklisted devices are tried to get claimed, and this happened 
above.

Blacklisting the devices works, or adding find_mutlipaths yes should also 
work, because
in that case only device which have more than one path (or are explicitly 
named) will be
claimed by multipath.

My 2ct.

Re: [ovirt-users] Problem wiht ovirt-node

[Fabian Deutsch]

Hey Chhristopher,

please see my inline replies.

- Original Message -
 Looks like that 12/22 ISO doesn't run the installer that I can tell.  I
 really haven't had any good luck with any of the recent ovirt-node stuff
 which is such a shame.  My last installation using the 3.5-pre ISO would
 install and then fail at grub/boot afterwards.  I'm not sure if I'm doing
 something wrong there, but I'm more or less taking all defaults in the
 install, so it is unexpected.

Can you give some details on the exact failure?

Besides that we know (and this is actually the reason why there is still no 
official
Node 3.5 release) that there are issues with a lot of hardware, due to changes 
to
udev, device-mapper, multipath, and kernel. And it took some time to really
identify and solve those issues with changes in our code.
Some recent patches (which landed just before and after christmas), are
addressing these issues.

We are currently in progress of giving this patches some wider testing,
but we are optimistic that these changes will address most of the hardware 
problems.

And we'll also do another scratch build to allow you to test those patches as 
well.

 I feel like enterprise-level virtualization relies upon having the minimal
 OS/install in order to match the other hypervisors.  I hate to think of
 just going to minimal CentOS/RHEL installs, but perhaps that's my best bet
 to get up and testing.
 
 What can the community do to help this along?  Perhaps requiring equivalent
 ovirt-node releases along with every release of ovirt may put the
 motivation behind it?  I'm willing to help test, however I can't put my
 original environment in a constant state of change, obviously.  I'm willing
 to build up some scenarios if that helps get to a
 stable/installable/functioning ovirt-node.  Those of us trying to prove
 this out vs. vmware/ESX need this.

There are many ways to help. Testing - like you did - are an important (but 
sometimes
painful) aspect, and I really appreciate that you continue to test!

So as mentioned above, there will be a new scratch build with more fixes 
related to
hardware support, and please watch this list for the link to the build.

That build will also pickup some recent hosted-engine fixes.

Thanks
fabian

 I installed ovirt node with hosted-engine using pre-release
  ovirt-node
3.5
 iso.

 When i shutdown the ovirt-node from menu everything down ok, ( i
register it
 as node in vm ). When i turn on the server next day, ovirt-node
  come up
with
 no vm was installed ( i use other server as storage with nfs). Nfs
  is
 working fine i see all resource if i do showmount -e nfs.server.

 But if i try to do hosted-engine --vm-status or any command with
 hosted-engine it suggest me to do a new deploy, but i have all
enviroment
 configured en my engine.

 I need to configure two ovirt-node, and then move it to datacenter,
  but
after
 shutdown vm engine is not seen by ovirt-node.
   
It's a know bug, it was recently fixed:
https://bugzilla.redhat.com/show_bug.cgi?id=1151339
   
hosted-engine in 3.5.1 will include this fix. General availability
  it's

 Fabian?

The idea of leveraging Fedora roles is a nice idea.

Surely an RFE can be opened against ovirt-node (the hypervisor part of oVirt),
but we need to see how this will fit into our plans.
I'm concerned that it will require a lot of work to create such a role, but
we'll only benefit on Fedora.
And currently we are quite focused on CentOS, because it's quite well received.

Speaking about benefits, I also wonder what benefits are. This needs more
investigations before we can answer it from the Node side.

Re: [ovirt-users] Node upgrade issue

 Hi everyone !
 
  I am  looking something about ovirt node upgrade .
 
 we are using a old version of ovirt node 3.1.  Also I test ovirt node
 3.5 . Somethings is puzzling me .
 
 1, In ovirt node 3.1 , it seemed I can't upgrade ovirt node ,because of
 Hostvg's existence.
 In Hostvg , something like ssh keys are stored here, I know this is
 important . Is it possible to let the node  inherit these things ? so that
 I can upgrade the node without remove things in hostvg .

Hey,

could you please explain the exact flow you tried?

  2, I made a ovirt-node-iso 3.5 version myself . But when I try to
 install it , it fails because the issue of selinux .
 
  In shell mode , type localectl ,it shows this . after setenforce 0 ,
 localectl will work well .

What branch did you use to build your iso?

And for SELinux denials: Catch /var/log/audit/audit.log and create new rules 
using
audit2allow.

   Thanks to everyone for the answers.  That helps clarify some basics for
   me.  I prefer to try and implement ovirt-node for the reasons stated
  above
   (small, defined OS with a smaller security/management footprint), but
  now I
   debate using CentOS 6 or RHEL 6.  I feel that oVirt-node is very
  important
   to being able to get an environment up and running securely without too
   much overhead, but perhaps I need to consider minimal OS installs +
  latest
   gluster release + 3.5 oVirt at this time.
 
  oVirt node can (btw) be deployed using PXE (Foreman, Cobbler), USB and CD
  media, and virtual media.
 
 
 That very much interests me since I utilize Cobbler currently for all of my
 provisioning.  I would assume that basically one would kickstart it like
 any other RHEL-based release.  Are you aware of any document that describes
 Cobbler+oVirt-Node by chance?

Hey,

for Node it's a bit different.
You can just use the kernel+initrd and some kernel arguments to deploy it via 
PXE.
No kickstart needed.

Our documentation is a bit lacking the details, but you can consult this docs:
http://red.ht/1xNNXak
http://red.ht/1vkmLRc

The should work for Node as well.

   One thing I was curious about is gluster support in oVirt-node.  What is
   the current status as far as glusterfs version and saving settings, etc.?
 
  The pre-release build from today contains glusterfs-3.6.
 
 
 Great!  Thanks for the information.  I've downloaded that ISO and I'm
 working on getting that deployed on a couple of test blades.

Great!
Let me know anything you would let us to know :)

 I sincerely hope that this is not answered elsewhere as I've done
  several

believe
 to be) basic questions (with perhaps some subs there):

 1)  What is the latest oVirt-node release and where would one
  download it
 (I appear to only see 3.4 -based releases of the ISO available)?  It
  is
 3.5-based and/or is there an upgrade path?  Which glusterfs release
  is
 currently included with oVirt-node?
   
Hey,
   
there are some 3.5 pre-release isos available here:
http://resources.ovirt.org/pub/ovirt-3.5-pre/iso/
   
They are quite old. The reason why there is still no Node, is that we
  are
experiencing
installation problems after CentOS 6.6 got released.
   
That is why there is no Node for 3.5 yet, becuase we don't want to
  provide
a Node which is dead on arrival. This ain't fun for anyone.
   
 2) As I understand it, newer releases of oVirt-node allow you to do
  an
 installation of the self-hosted engine at this time.  Is that
  correct?
   
Yes, that will work. Due to problems mentioned above, we still need to
  do
some
fixes to the hosted-engine part of Node, but once they land, HE will
  work
on Node.
   
 3) Is there any functionality that one would be losing out on by
deploying
 oVirt via oVirt-node vs. using full-OS installation?  Which is the
  more
 recommended?
   
Yes, ovirt-node is not as customizable as a regular host.
I.e. you can not (easily) modify the boot process, or install custom
  rpms.
   
Sometimes this is seen as a restriction, other see this as a well
  defined
environment.
   
 Again, I apologize if these questions are covered somewhere, but I
  felt
 like asking them in a direct fashion so as to clear up my own
ignorance.  I
 appreciate any feedback and information that you could share.
   
No, no worries. There weren't any Node updates (besides the weekly
  meeting
minutes)
for a while.
   
We still traget to release Node for oVirt 3.5 ASAP.

 installation of the self-hosted engine at this time.  Is that correct?

Yes, that will work. Due to problems mentioned above, we still need to do some
fixes to the hosted-engine part of Node, but once they land, HE will work on 
Node.

 3) Is there any functionality that one would be losing out on by deploying
 oVirt via oVirt-node vs. using full-OS installation?  Which is the more
 recommended?

Yes, ovirt-node is not as customizable as a regular host.
I.e. you can not (easily) modify the boot process, or install custom rpms.

Sometimes this is seen as a restriction, other see this as a well defined
environment.

 Again, I apologize if these questions are covered somewhere, but I felt
 like asking them in a direct fashion so as to clear up my own ignorance.  I
 appreciate any feedback and information that you could share.

No, no worries. There weren't any Node updates (besides the weekly meeting 
minutes)
for a while.

We still traget to release Node for oVirt 3.5 ASAP.

[ovirt-users] oVirt Node 3.5 build available for testing

[Fabian Deutsch]

Hey,

finally we reached a stage again where we can provide an oVirt Node.
The following oVirt Node ISO contains the oVirt 3.5.0 packages.

Please go ahead, test it and provide feedback in case of issues.

https://fedorapeople.org/~fabiand/node/3.5/ovirt-node-iso-3.5.0.ovirt35.20141114.0.el6.iso

To learn something more about oVirt Node please visit
http://www.ovirt.org/Node
http://www.ovirt.org/Quick_Start_Guide#Install_oVirt_Node


Please note that this is still an pre-release, and we are aware that there are 
still
issues with the hosted-engine part of Node.
But this part will see some (already pending updates) in the near future.

Re: [ovirt-users] Latest ovirt-node release/installation

[Fabian Deutsch]

- Original Message -
 Thanks to everyone for the answers.  That helps clarify some basics for
 me.  I prefer to try and implement ovirt-node for the reasons stated above
 (small, defined OS with a smaller security/management footprint), but now I
 debate using CentOS 6 or RHEL 6.  I feel that oVirt-node is very important
 to being able to get an environment up and running securely without too
 much overhead, but perhaps I need to consider minimal OS installs + latest
 gluster release + 3.5 oVirt at this time.

oVirt node can (btw) be deployed using PXE (Foreman, Cobbler), USB and CD 
media, and virtual media.

 One thing I was curious about is gluster support in oVirt-node.  What is
 the current status as far as glusterfs version and saving settings, etc.?

The pre-release build from today contains glusterfs-3.6.

- fabian

 Thanks again!

   I sincerely hope that this is not answered elsewhere as I've done several
   searches and have yet to find a solid answer.  I have three (what I
  believe
   to be) basic questions (with perhaps some subs there):
  
   1)  What is the latest oVirt-node release and where would one download it
   (I appear to only see 3.4 -based releases of the ISO available)?  It is
   3.5-based and/or is there an upgrade path?  Which glusterfs release is
   currently included with oVirt-node?
 
  Hey,
 
  there are some 3.5 pre-release isos available here:
  http://resources.ovirt.org/pub/ovirt-3.5-pre/iso/
 
  They are quite old. The reason why there is still no Node, is that we are
  experiencing
  installation problems after CentOS 6.6 got released.
 
  That is why there is no Node for 3.5 yet, becuase we don't want to provide
  a Node which is dead on arrival. This ain't fun for anyone.

  this means probably a slightly longer cycle than the 6 months we currently
  do.
 
 We're not so good in keeping up with deadlines - our recent 3.5 version
 slipped for 2.5 months past the original plan. With longer cycles, this
 is even harder to control.
 
 Can we instead break the heavier features to smaller phases, that are
 easier to maintain, and deliver the complete feature in 3.7?

Hey,

yep, I think this is a good idea to get control over the big features.

- fabian

  with many of the features requiring way newer versions of some of the
  components, I think we should plan for 3.6 cluster to require an .el7
  host
  (expecting even 7.1 to be out before we release oVirt 3.6).
  
  so i want us to plan for:
  - oVirt 3.6 supports .el6 and .el7 hosts in 3.5 cluster (and for fedora
- fc20?)
  - oVirt 3.6 supports .el7 in 3.6 cluster (and for fedora - fc21?)

Re: [ovirt-users] importing a qcow2 disk into ovirt 3.5?

[Fabian Deutsch]

- Original Message -
 I've just been doing some searching to try and work out how to get a vmware
 windows VM into ovirt.
 It seems that the newest virtv2v has dropped support for importing from an
 ESXi standalone machine - and now only works with vcenter.  I didn't have
 any success with using the current virt-v2v attaching to an ESXi host.
 
 
 I've prepared the VM by first removing the vmware tools and have installled
 the various virtio drivers, as well as running the 'mergeide' registry file
 to enable IDE.  I've used 'qemu-img' to convirt this VMDK file to QCOW2.  It
 does not appear that there is a straightforward way for me to import this
 new qcow2 disk into ovirt.
 
 It seems my best option at the moment is to export the VMware VM as an OVA
 and then try and use a newer virt-v2v to import this into ovirt.

Hey Paul,

I think the OVA is what you need for Engine.
Once you get that file you can import it.
So: Use the OVA offered by the VMWare thing, or use a script like this one:

http://jenkins.ovirt.org/user/fabiand/my-views/view/Node/job/ovirt-appliance_engine-3.5_master_merged/ws/ovirt-appliance/engine-appliance/scripts/create_ova.py
depends on https://github.com/redhat-imaging/imagefactory

To convert the qcow2 to an OVA.

- fabian

 Alternatively I could construct a VM in virt-manager and attach the converted
 qcow2 disk to it, and then use virt-v2v to import this into ovirt.
 
 Can someone suggest an alternative course of action?  It seems strange that I
 can't just import a disk into ovirt,  construct a VM and attach the disk.
 
 Is there anything int he works to make this process easier?
 
 Thanks,
 Paul

 I remember not so much time ago that VMware generated OVA format was NOT

 see for example this thread:
 http://lists.ovirt.org/pipermail/users/2014-August/027059.html

Oh, I didn't recall that a few minutes ago.

 Did anything change in the mean time and is perhaps the new virt-v2v
 available with ova functionality in it?

AFAIK the new virt-v2v is still not supporting OVAs.

That means, we need to create the ovas ourselfs using some script (like the one 
above).

 Hi.
 
 I have a issue with 3.1.0_master (20140912.0) on following hardware:
 
 ProLiant BL460c Gen8
 FLB Adapter 1: HP FlexFabric 10Gb 2-port 554FLB Adapter
 
 I can install node but when booting the server I get I/O errors as if LUN is
 offline.

Hey Raul,

can you describe these errors or provide a screenshot/log?

 Logging into admin (TUI) console is not possible.
 
 If I reboot and set the rootpw I can log in and see that /var/log is mounted
 read-only:
 
 mount: cannot remount block device /dev/mapper/HostVG-Logging read-write, is
 write-protected
 
 multipath -ll shows that all paths are OK, but if I look at dmesg ouput, I
 see device-mapper: multipath: Failing path x:xx. was logged at boot for all
 paths.
 
 I have successfully installed previous node iso version (3.0) and plain
 CentOS on this hardware.

Did you try booting in permissive mode (appending enforcing=0 to the kernel 
cmdline).

Greetings
fabian

 In addition, I've uploaded this image to the oVirt public glance repository,

 So, if you already have an oVirt environment, and you would like to play with

 template, and create VMs from it.
 (see

 Haven't tested this image yet, but I'm importing it as a template as we speak

I'm working on this, please remove it from glance again (kudos for uploading it

 Lets first try to isolate your FC issure. So you are using the latest
 ovirt-node? EL6? Keep in mind, the kernel is standard Linux and therefore
 should support Qlogic adapters out of the box (IMHO they are the best
 supported HBAs in Linux).
 Please try a:
 # lsmod  | grep qxl
 to see whatever the qxl module is loaded. Keep in mind you can run into
 problems with other conrollers in your host, though I only had this with LSI
 SAS / FC controllers so far.
 
 Further check on the FC switch if the N port is logged in and the zoning is
 correct.
 
 Finally, check with
 # lsscsi
 if you can see the luns.
 
  Also having a lot of issues with configuring the network.  I configure
  an interface I can ping it, but it shows as unconfigured... on one host
  I have added it to the manager and I see the interfaces anyway, but on

  maybe?

 because of dm-multipath, multipath.conf might blacklist here. My nodes
 are plain EL6 and I have multipath enabled - but I do not know if

 sense because of iscsi-multipathing in ovirt 3.4).

Well, we did some multipath changes lately. Let#s see what Bill says:

Re: [ovirt-users] Network Address Change

[Fabian Deutsch]

- Original Message -
 Hi All:
 To be honest I do not see any config file in the host node
 /etc/ovirt-node inside, so even I put in the global maintenance mode I
 still don't know how to change the host to the new IP address.

Hey Paul,

if you are using oVirt Node (btw what version are you using?), then there are a 
couple of files, there is
/etc/default/ovirt

and the well known ifcfg files:
/etc/sysconfig/netwprk-scripts/ifcfg-*

And some other paths which are handled by vdsm.

And vdsm is actually managing the network configuration when a Node is 
registered, that means, it can be that any changes to the configuration files 
get overwritten by vdsm again.

Maybe Toni can say something about this.

And I am also not sure if Engine will still recognize a Node, when you change 
the IP of the Node, without letting the Engine know about that.

Sandro, do you know how you can tell Engine that the IP of a Node changed?

Greetings
fabian

  and of course I need to change the ovirtmgmt interface IP too, I think
  just change the above line could do the tick, but where could I change
  the
  other host IP in the cluster ?
  I think I have to be lost all the host as once changed the hosted-engine
  host IP as it is in diff. sub net.
  Does there any command line tools could do that or someone has such
  experience could share?
  Well, I think you can move the hosts to global maintenance, shutdown the
  hosted engine vm, move the first host and the vm to the new network.
  After that you should be able to move the other hosts to the new network.
  When finished you can exit global maintenance.
 
  Never tested such scenario so if any other can provide more info and maybe
  create a wiki page it would be nice.
  Not sure about what happen with the certificates if they've been generated
  using ip address instead of FQDN, probably they won't be valid anymore
  after the network change.

 Are there plans for an el7 based ovirt node iso for ovirt 3.5?

Hey Paul,

yep - we are actually working on el7 support. And the current master should be 
in a not to bad shape.

We still need to see when we switch to provide el7 based Nodes, which is not 
only limited by the code readiness but also by the supporting infrastructure, 
which needs to be migrated to el7.

 I see in the announcement for the RC that there is an el6 based node iso.

 It looks like support for el7 as a host is coming along pretty well.

  Ah, great !!! And is there a Debian flavor ?

No. Currently not.
But Node became more stable over the last months, and you might want to try 
this snapshot build:
http://resources.ovirt.org/pub/ovirt-3.5-pre/iso/ovirt-node-iso-3.5.0.ovirt35.20140805.0.el6.iso

  It is my favorite distribution ;-)
 
 Not yet, and I don't know if it is on the roadmap.
 you could maybe create your own, it's basically
 this workflow:
 install $distro
 throw out all unneeded stuff
 install virt stuff (libvirt+vdsm)
 apply hardening (selinux etc)
 create iso
 
 I go with centos minimal and customize
 that myself, works really well.
 
 I don't know if vdsm is already complete
 platform independent (afaik it should be).
 
 the initial development was all on fedora
 and el6, so this is where it runs best atm.
 
 but I know for sure there are plans to
 make it distribution agnostic, but
 I don't know if this includes a pre-created
 iso for ovirt-node based on debian or gentoo.
 
 maybe fabian can shed some light on the
 future plans.

The current Node can really only be created for Fedora related distrios, so 
CentOS, RHEL and Fedora itself.
The reason for this is that all parts the build process is tailored around 
Fedora related tools. Namely kickstarts, and lviecd-tools.

We are currently thinking about how we can change Node and make it more 
friendly, the distro agnostic idea also goes into this thoughts - but there is 
nothing concrete on that front yet.

That's it from the Node side.

- fabian

 alon can maybe give some insight into
 how distribution agnostic ovirt already is
 and what future plans are,
 thus cc'ing them.

 Could I ask if an install-to-host option is available?
 Also that the memtest  image integrity tests are available at boot.

Yep - The installation is the default option.

 I've also noted that there are not corresponding MD5 sums of images
 available on sites, so it's tricky to validate/verify the integrity of
 images downloaded before flashing.

The iso is checking itself when you boot it up. But yes, let me attach the 
md5sums of upcoming ovirt-node-iso builds.

[ovirt-users] Weekly oVirt Engine Appliance builds

[Fabian Deutsch]

Hey,

Finally there are weekly Fedora 19 based oVirt Engine Appliance builds.

They can be found in oVirt’s jenkins instance:
http://jenkins.ovirt.org/view/All/job/ovirt-appliance_master_merged/

An ova file is created, this can either be used with Engine or you can extract 
it (it's a compressed tarball) and use it with four favorite virtualization 
solution.

[ovirt-users] oVirt Node ISO for 3.5-pre

[Fabian Deutsch]

Hey,

here is another draft ISO which is intended to be used for testing with oVirt 
3.5.

This ISO also provides for the first time the oVirt Node Hosted Engine plugin.

http://resources.ovirt.org/pub/ovirt-3.5-pre/iso/ovirt-node-iso-3.5.0.ovirt35.20140707.el6.iso

We've learned from the past: To circumvent some SELinux issues, please append 
enforcing=0 to the kernel commandline on boot. 

And please provide us your feedback, so we can take a look and address the 
problem.

Greetings
fabian

Re: [ovirt-users] No configured networking after node image deploy

[Fabian Deutsch]

 Hi,
 
 Using latest node image I'm having a problem with networking after node
 deploy through http://www.ovirt.org/Features/AdvancedForemanIntegration
 http://www.ovirt.org/Features/AdvancedForemanIntegration.

 All network devices are unconfigured and registration of the node fails.
 When I disable-enable dhcp I get an error in the admin gui. supervdsm 
 ovirt-node.log: http://pastebin.com/8bT8aF2x http://pastebin.com/8bT8aF2x

Hey Jorick,

first - thanks for testing.

To debug this, could you please provide the files
/var/log/ovirt-node.log
/var/log/ovirt.log

And - can you register the Node manually?

Thanks
fabian

currently we don't have this rpm around. But I am optimistic that we

Hey Simon,

I was also investigating both the steps you did. And was also about to

We basically need some patches to change the defaults on Node, to let
gluster work out of the box.

This would include persisting the correct paths and enabling glusterd if
enabled.

 I've taken a look through 
 http://www.ovirt.org/Node_Troubleshooting#Making_changes_last_.2F_Persisting_changes

 To get glusterd to start on boot, do I need to manually persist /etc/rc* 
 files?
 
 I see files /var/lib/glusterd mentioned in /etc/rwtab.d/ovirt. Is this a 
 list of the files/dirs that should be persisted automatically? If so, is it 
 recursive and should it include everything in /var/lib/glusterd/vols?

  I am working through the setup of oVirt node for a 3.4.1 deployment.
 
 
 
  I setup some glusterfs volumes/bricks on oVirt Node Hypervisor 
  release 3.0.4
  (1.0.201401291204.el6) and created a storage domain. All was working 
  OK until I rebooted the node and found that the glusterfs

  Is there something I should be doing to persist any glusterfs 
  configuration so it survives a node reboot?
 
 
 
  Many thanks,

  Hi Simon,
  it actually sounds like a bug to me, as node are supposed to support 
  gluster.
 
  Ryan / Fabian- thoughts?
 
  Hey,
 
  I vaguely remember that we were seeing a bug like this some time ago.
  We fixed /var/lib/glusterd to be writable (using tmpfs), but it can 
  actually be that we need to persist those contents.
 
  But Simon, can you give details which configuration files are missing 
  and why glusterd is not starting

  Subject: [ovirt-users] Persisting glusterfs configs on an oVirt node
  
  
  
  I am working through the setup of oVirt node for a 3.4.1 deployment.
  
  
  
  I setup some glusterfs volumes/bricks on oVirt Node Hypervisor release 3.0.4
  (1.0.201401291204.el6) and created a storage domain. All was working OK
  until I rebooted the node and found that the glusterfs configuration had not
  been retained.
  
  
  
  Is there something I should be doing to persist any glusterfs configuration
  so it survives a node reboot?
  
  
  
  Many thanks,
  
  
  
  Simon
  
 
 Hi Simon,
 it actually sounds like a bug to me, as node are supposed to support
 gluster.
 
 Ryan / Fabian- thoughts?

Hey,

I vaguely remember that we were seeing a bug like this some time ago.
We fixed /var/lib/glusterd to be writable (using tmpfs), but it can
actually be that we need to persist those contents.

But Simon, can you give details which configuration files are missing
and why glusterd is not starting?

Thanks
fabian

 Either way I suggest you take a look in the below link-
 http://www.ovirt.org/Node_Troubleshooting#Making_changes_last_.2F_Persisting_changes
 
 Let s know how it works.
 
 Doron

Re: [ovirt-users] is ovirt-node.iso supposed to create a readonly filesystem?

Yep. Node has a read-only root filesystem, which has some overlays to
allow limited changes.

  getting LVM volume group UUID overruns.

Do you mean collissions here, or can you explain it a bit more.

  I'm using direct attach fiber
  channel, and everything looks good, but there appears to be some UUID
  or Volume group name in my list of LUNs that matches  some sort of lvm
  key from the node root file system.  This only happens on the node
  that I installed from the iso. I built all of these nodes in a vm,
  then set that image to boot. I did NOT copy that lun from one top the
  others, nor are any of the hosts luns visible from any of the other
  hosts.  Not sure where to start. I'm going to reinstall from a
  bootable cd directly connected to my blade and see if that clears up
  the problem.

Could you please explain abit more about your setup.
If you have a SAN, an all LUNs of it are visible by all hosts, and you
install Node on more than one host, then it could come to collsisions.

Node is using some predefined LV names, e.g. Root, which will cause
collisions if there are more LUNs with LVs which have the same name.

  Subject: [Users] node spin including qemu-kvm-rhev?
  
  I understand that there are ongoing discussions with the Centos people
  regarding a suitable home for recompiled qemu-kvm packages.
  Given that the ovirt node is our own spin, is there any reason why that
  couldn't include the recompiled qemu-kvm packages that will then allow us to
  use live snapshots and do live migrations? Itamar recently mentioned that we
  already build these via a jenkins task.
  
  Nodes built on top of a Centos install will still be an issue but I think 
  its
  reasonable that the ovirt-node iso could include these custom packages.
  This way we don't have to potentially wait until 3.4.1 or 3.5 to get the 
  live
  snapshot/migration features. The caveat would be that these features would
  only be supported if the nodes were all ovirt node iso based.
  
  What are people's thoughts?
  
  
 
 Sounds reasonable as long as you understand mix and match will become an 
 issue.
 The questions is how do we differentiate between the nodes to make sure no one
 mixes them by mistake?

Hey,

yeah - that is also my concern.
oVirt node has a mechanism (in master) to expose that features are
present or not, but I don't know if vdsm has the capability to pass this
on to Engine, and if Engine has the logic to detect incompatabilities
based on the underlying qemu-kvm-rhev version.

 My mail client might mangle the bottom-posting here, so we'll see how

 I saw a post from Fabian that he had re-enabled jenkins builds of the
 node image based on Fedora 19/20 (but not yet including the VDSM
 plugin).  Presumably the main goal of this is to ensure that things in
 node land are OK for an upcoming spin based on EL7?

EL7 is one point, but there were users also asking for Fedora based
Nodes and we use Fedora for development, to have stable Nodes (at some
point later) based on CentOS.

 If ovirt does go back to having Fedora and EL based node images in the
 short term it would mean that live migration will work on the Fedora
 images.

The Fedora based images are at least for now available from Jenkins.

 If it was also decided to allow the EL based node image to include the
 recompiled qemu-kvm-rhev package the Ovirt release notes could then
 say that when using an ovirt node image live migration is supported,
 as is when a fedora install has the ovirt hypervisor packages
 installed.

What is this ovirt hypervisor package you mention?

- fabian

 It would only be that an EL based system - built up to then also
 include the ovirt hypervisor packages - that live migration would not
 be supported - at this stage.
 This can change when the details are further worked out with the
 Centos people about how the updated qemu-kvm packages will be hosted
 and made available.
 In the meantime, people that want to set things up so that live
 migration is there can do so.
 
 Once live migration is in place I think it would be interesting to try
 and find out from people interested (or already testing ovirt) that
 have VMware backgrounds/experience what they think is the the largest
 outstanding issue feature wise when comparing ovirt to Vcenter.  What
 would stop them from migrating from vcenter to ovirt?

Hey Paul,

you could try sending text-only emails :)

 By the 'ovirt hypervisor packages' I meant installing the OS first of
 all and then making it into an ovirt 'node' by installing the required
 packages, rather than installing from a clean slate with the ovirt
 node iso.  Sorry if that was a bit unclear.

Okay - thanks for the explanation.
In general I would discourage from installing the ovirt-node package ona
normal host.
If you still want to try it be aware that the ovirt-node pkg might mess
with your system.
