Re: [ovirt-users] How to setup OVS using python SDK ?

[Yaniv Dary]

You should not use the OVS hook or native implementation.
We don't feel this feature is ready and we stopped its development recently.
You should look at the OVN implementation, there is a deep dive planned for
this soon, please look it up.

Re: [ovirt-users] problem to start vm after disk resizing

[Fred Rolland]

Hi,

What version are you using?

The LV should not have been changed,
Were there any steps done directly on the storage not via the engine ?

Please perform a getDeviceList and check the output on each of the hosts
and see that the device that has been increased is reported with the right
size on all of the hosts.

Thanks,

Fred

As I wrote, no qemu package proposed. Because oVirt provided qemu is
greater in version in respect with 7.3
In fact, as I already wrote, I have now
qemu-kvm-common-ev-2.3.0-31.el7.16.1.x86_64
qemu-img-ev-2.3.0-31.el7.16.1.x86_64
qemu-kvm-ev-2.3.0-31.el7.16.1.x86_64
qemu-kvm-tools-ev-2.3.0-31.el7.16.1.x86_64

Your link doesn't map with any repo I have or oVirt configures... so my
system cannot catch its packages

Regarding CentOS 7.3
I find qemu-kvm-1.5.3-126.el7.x86_64.rpm here:
http://mirror.centos.org/centos/7/os/x86_64/Packages/
and it should be the version delivered with CentOS 7.3 (dated 20/11)
No qemu packages in
http://mirror.centos.org/centos/7/updates/x86_64/Packages/
So it means no updates for it.

[ovirt-users] hosted_storage locked

[Gary Pedretty]

Just setup a new hosted-engine Data Center.  With 3 hosts and gluster based 
storage domains.  Used the latest installers.  Everything went well, until I 
got the engine deployed and each host setup and went to the web interface for 
the first time.

After adding the master storage domain, the hosted_storage added itself like 
usual, but remained locked.   Everything is working just fine with the 
exception of no listing of the engine as a VM under that tab or the icon on the 
current host.   The Volumes tab does not show anything on the hosted_storage, 
but all the other volumes including the master data and a second data all show 
normal status for bricks.  Error log is not reporting anything unusual either.  
All the gluster volumes including the engine (hosted_storage) show good status 
via command line in the hosts.

Going to let it run for a day or so before I add any VMs.

Any ideas?

Gary

Hi
For long time I've been looking for proper support in ovirt for
Open vSwitch so I'm happy that it is moving in the right
direction. However, there seems to still be a dependency on a
ovirtmgmt bridge and I'm unable to move that to the OVN provider.

The hosting center where I rent hw instances has a bit special
network setup, so I have one physical network port with a /32
netmask and point-to-point config to router. The physical port I
connect to a ovs bridge which has the public ip. Since ovirt
always messes up the network config when I've tried to let it have
access to the network config for the physical port, I've set eht0
and ovsbridge0 as hidden in vdsm.conf.

I then create a bridge for use with ovirt, with a private address.
With the OVN provider I am now able to import these into the
engine and it looks good. When creating a VM I can select that it
will have a vNic on my OVS bridge.

However, I can't start the VM as an exception is thrown in the log:

Looking at that section of code where the exception is thrown, I
see that it iterates over host networks to find required networks,
which I assume is ovirtmgmt. In the host network setup dialog I
don't see any networks at all but it lists ovirtmgmt as required.
It also list the OVN networks but these can't be statically
assigned as they are added dynamically when needed, which is fine.

I believe that I either need to remove ovirtmgmt network or
configure that it is provided by the OVN provider, but neither is
possible. Preferably it shouldn't be hardcoded which network is
management and mandatory but be possible to configure.

Re: [ovirt-users] Issue with OVN/OVS and mandatory ovirtmgmt network

[Marcin Mirecki]

Hi Sverker,

The management network is mandatory on each host. It's used by the
engine to communicate with the host.
Looking at your description and the exception it looks like it is missing. 
The error is caused by not having any network for the host 
(network list retrieved in InterfaceDaoImpl.getHostNetworksByCluster - which
gets all the networks on nics for a host from vds_interface table in the DB).

Could you maybe create a virtual nic connected to ovsbridge0 (as I understand 
you
have no physical nic available) and use this for the management network?

> I then create a bridge for use with ovirt, with a private address.
I'm not quite sure I understand. Is this yet another bridge connected to 
ovsbridge0?
You could also attach the vnic for the management network here if need be.

Please keep in mind that OVN has no use in setting up the management network.
The OVN provider can only handle external networks, which can not be used for a
management network.

Marcin

Re: [ovirt-users] Issue with OVN/OVS and mandatory ovirtmgmt network

[Sverker Abrahamsson]

Hi Marcin
Yes, that is my issue. I don't want to let ovirt/vdsm see eth0 nor 
ovsbridge0 since as soon as it sees them it messes up the network config 
so that the host will be unreachable.


I have an internal OVS bridge called ovirtbridge which has a port with 
IP address, but in the host network settings that port is not visible. 
It doesn't help to name it ovirtmgmt.


The engine is able to communicate with the host on the ip it has been 
given, it's just that it believes that it HAS to have a ovirtmgmt 
network which can't be on OVN.

Hi
For long time I've been looking for proper support in ovirt for Open vSwitch
so I'm happy that it is moving in the right direction. However, there seems
to still be a dependency on a ovirtmgmt bridge and I'm unable to move that
to the OVN provider.

The hosting center where I rent hw instances has a bit special network setup,
so I have one physical network port with a /32 netmask and point-to-point
config to router. The physical port I connect to a ovs bridge which has the
public ip. Since ovirt always messes up the network config when I've tried
to let it have access to the network config for the physical port, I've set
eht0 and ovsbridge0 as hidden in vdsm.conf.


I then create a bridge for use with ovirt, with a private address. With the
OVN provider I am now able to import these into the engine and it looks
good. When creating a VM I can select that it will have a vNic on my OVS
bridge.

However, I can't start the VM as an exception is thrown in the log:

I just verified and unfortunately the virtual ports are not visible in engine 
to assign a network to :(
I'm afraid that the engine is not ready for such a scenario (even if it works).
Please give me some time to look for a solution.

Re: [ovirt-users] Issue with OVN/OVS and mandatory ovirtmgmt network

[Marcin Mirecki]

Sverker,

Can you try adding a vnic named veth_* or dummy_*,
(or alternatively add the name of the vnic to 
vdsm.config fake_nics), and setup the management
network using this vnic?
I suppose adding the vnic you use for connecting
to the engine to fake_nics should make it visible
to the engine, and you should be able to use it for
the setup.

Marcin

Re: [ovirt-users] Issue with OVN/OVS and mandatory ovirtmgmt network

I have tried various variants to create an interface with the dummy

legacy bridge ovirtmgmt but ovirt-engine doesn't see those neither.

Could you maybe create a virtual nic connected to ovsbridge0 (as I

I then create a bridge for use with ovirt, with a private address.

Hi
For long time I've been looking for proper support in ovirt for Open
vSwitch
so I'm happy that it is moving in the right direction. However, there
seems
to still be a dependency on a ovirtmgmt bridge and I'm unable to move that
to the OVN provider.

The hosting center where I rent hw instances has a bit special network
setup,
so I have one physical network port with a /32 netmask and point-to-point
config to router. The physical port I connect to a ovs bridge which has
the
public ip. Since ovirt always messes up the network config when I've tried
to let it have access to the network config for the physical port, I've
set
eht0 and ovsbridge0 as hidden in vdsm.conf.


I then create a bridge for use with ovirt, with a private address. With
the
OVN provider I am now able to import these into the engine and it looks
good. When creating a VM I can select that it will have a vNic on my OVS
bridge.

However, I can't start the VM as an exception is thrown in the log:

Re: [ovirt-users] I wrote an oVirt thing

[Nathanaël Blanchet]

Hi,

I understand that ovirt-shell is deprecated, but I need it for the moment.

I've just done a pip install upgrade ovirt-engine-sdk-python on my 
ubuntu laptop and now ovirt-shell is totally broken, saying : 
ImportError: No module named ovirtsdk.xml.


Can I go back to the previous SDK? How can I fix it?

Thanks.

I can't see it

 It is working on top of the v3 api, which we plan to remove in 4.2.

Haven't seen a deprecation bug for this as well
in 
https://bugzilla.redhat.com/buglist.cgi?quicksearch=classification%3Aovirt%20v3%20api

If we want people to know about it we need to publish it somehow and for
the way we build release notes we need deprecation bugs for it to be
published.
  

There were no such bugs. I have just created them:

   Deprecate version 3 of the API
   https://bugzilla.redhat.com/1399724


This ^ bug had an important typo in the description that Martin Sivak
pointed out. I have closed it and replaced with this one, which is
hopefully more correct:

   Deprecate version 3 of the API
   https://bugzilla.redhat.com/1399750


   Deprecate version 3 of the Python SDK
   https://bugzilla.redhat.com/1399714

   Deprecate version 3 of the Java SDK
   https://bugzilla.redhat.com/1399717

   Deprecate the ovirt-shell tool
   https://bugzilla.redhat.com/1399709


 So better not use it.

 Alternatives are to use the SDKs according to your preference (we
 have Java, python and Ruby SDKs) or the ansible modules mentioned
 above by Moran (instead of writing scripts you can write playbooks
 to do various operations ).

 Oved

The CLI depends completely on version 3 of the SDK, and it won't work
with version 4. You need to explicitly install version 3 of the SDK:

  pip install ovirt-engine-sdk-python==3.6.9.2

Re: [ovirt-users] Issue with OVN/OVS and mandatory ovirtmgmt network

Hi
I first tried to set device name to dummy_0, but then ifup did not 
succeed in creating the device unless I first did 'ip link add dummy_0 
type dummy' but then it would not suceed to establish the if on reboot.


Setting fake_nics = dummy0 would not work neither, but this works:

fake_nics = dummy*

The engine is now able to find the if and assign bridge ovirtmgmt to it.

However, I then run into the next issue when starting a VM:

This VM has a nic on ovirtbridge, which comes from the OVN provider.

Sverker,

Can you try adding a vnic named veth_* or dummy_*,
(or alternatively add the name of the vnic to
vdsm.config fake_nics), and setup the management
network using this vnic?
I suppose adding the vnic you use for connecting
to the engine to fake_nics should make it visible
to the engine, and you should be able to use it for
the setup.

In addition I had to add an alias to modprobe:

[root@h2 modprobe.d]# cat dummy.conf
alias dummy0 dummy

Hi
I first tried to set device name to dummy_0, but then ifup did not 
succeed in creating the device unless I first did 'ip link add dummy_0 
type dummy' but then it would not suceed to establish the if on reboot.


Setting fake_nics = dummy0 would not work neither, but this works:

fake_nics = dummy*

The engine is now able to find the if and assign bridge ovirtmgmt to it.

However, I then run into the next issue when starting a VM:

This VM has a nic on ovirtbridge, which comes from the OVN provider.

Sverker,

Can you try adding a vnic named veth_* or dummy_*,
(or alternatively add the name of the vnic to
vdsm.config fake_nics), and setup the management
network using this vnic?
I suppose adding the vnic you use for connecting
to the engine to fake_nics should make it visible
to the engine, and you should be able to use it for
the setup.

I have an internal OVS bridge called ovirtbridge which has a port with
IP address, but in the host network settings that port is not visible.
I just verified and unfortunately the virtual ports are not visible 
in engine

to assign a network to :(
I'm afraid that the engine is not ready for such a scenario (even if it
works).
Please give me some time to look for a solution.

Hi Marcin
Yes, that is my issue. I don't want to let ovirt/vdsm see eth0 nor
ovsbridge0 since as soon as it sees them it messes up the network 
config

so that the host will be unreachable.

I have an internal OVS bridge called ovirtbridge which has a port with
IP address, but in the host network settings that port is not visible.
It doesn't help to name it ovirtmgmt.

The engine is able to communicate with the host on the ip it has been
given, it's just that it believes that it HAS to have a ovirtmgmt
network which can't be on OVN.

Hi Sverker,

The management network is mandatory on each host. It's used by the
engine to communicate with the host.
Looking at your description and the exception it looks like it is
missing.
The error is caused by not having any network for the host
(network list retrieved in 
InterfaceDaoImpl.getHostNetworksByCluster -

which
gets all the networks on nics for a host from vds_interface table 
in the

DB).

Could you maybe create a virtual nic connected to ovsbridge0 (as I
understand you
have no physical nic available) and use this for the management 
network?



I then create a bridge for use with ovirt, with a private address.
I'm not quite sure I understand. Is this yet another bridge 
connected to

ovsbridge0?
You could also attach the vnic for the management network here if 
need

be.

Please keep in mind that OVN has no use in setting up the management
network.
The OVN provider can only handle external networks, which can not 
be used

for a
management network.

Hi
For long time I've been looking for proper support in ovirt for Open
vSwitch
so I'm happy that it is moving in the right direction. However, 
there

seems
to still be a dependency on a ovirtmgmt bridge and I'm unable to 
move

that
to the OVN provider.

The hosting center where I rent hw instances has a bit special 
network

setup,
so I have one physical network port with a /32 netmask and
point-to-point
config to router. The physical port I connect to a ovs bridge 
which has

the
public ip. Since ovirt always messes up the network config when I've
tried
to let it have access to the network config for the physical 
port, I've

set
eht0 and ovsbridge0 as hidden in vdsm.conf.


I then create a bridge for use with ovirt, with a private 
address. With

the
OVN provider I am now able to import these into the engine and it 
looks
good. When creating a VM I can select that it will have a vNic on 
my OVS

bridge.

However, I can't start the VM as an exception is thrown in

[ovirt-users] New oVirt user

[Jim Kusznir]

Hello:

I've been involved in virtualization from its very early days, and been
running linux virtualization solutions off and on for a decade.
Previously, I was always frustrated with the long feature list offered by
many linux virtualization systems but with no reasonable way to manage
that.  It seemed that I had to spend an inordinate amount of time doing
everything by hand.  Thus, when I found oVirt, I was ecstatic!
Unfortunately, at that time I changed employment (or rather left employment
and became self-employed), and didn't have any reason to build my own virt
cluster..until now!

So I'm back with oVirt, and actually deploying a small 3-node cluster.  I
intend to run on it:
VoIP Server
Web Server
Business backend server
UniFi management server
Monitoring server (zabbix)

Not a heavy load, and 3 servers is probably overkill, but I need this to
work, and it sounds like 3 is the magic entry level for all the
cluster/failover stuff to work.  For now, my intent is to use a single SSD
on each node with gluster for the storage backend.  I figure if all the
failover stuff actually working, if I loose a node due to disk failure, its
not the end of the world.  I can rebuild it, reconnect gluster, and restart
everything.  As this is for a startup business, funds are thin at the
moment, so I'm trying to cut a couple corners that don't affect overall
reliability.  If this side of the business grows more, I would likely
invest in some dedicated servers.

So far, I've based my efforts around this guide on oVirt's website:
http://www.ovirt.org/blog/2016/08/up-and-running-with-ovirt-4-0-and-gluster-storage/

My cluster is currently functioning, but not entirely correctly.  Some of
it is gut feel, some of it is specific test cases (more to follow).  First,
some areas that lacked clarity and the choices I made in them:

Early on, Jason talks about using a dedicated gluster network for the
gluster storage sync'ing.  I liked that idea, and as I had 4 nics on each
machine, I thought dedicating one or two to gluster would be fine.  So, on
my clean, bare machines, I setup another network with private NiCs and put
it on a standalone switch.  I added hostnames with a designator (-g on the
end) for the IPs for all three nodes into /etc/hosts on all three nodes so
now each node can resolve itself and the other nodes on the -g name (and
private IP) as well as their main host name and "more public" (but not
public) IP.

Then, for gdeploy, I put the hostnames in as the -g hostnames, as I didn't
see anywhere to tell gluster to use the private network.  I think this is a
place I went wrong, but didn't realize it until the end

I set up the gdeploy script (it took a few times, and a few OS rebuilds to
get it just right...), and ran it, and it was successful!  When complete, I
had a working gluster cluster and the right software installed on each node!

I set up the engine on node1, and that worked, and I was able to log in to
the web gui.  I mistakenly skipped the web gui enable gluster service
before doing the engine vm reboot to complete the engine setup process, but
I did go back in after the reboot and do that.  After doing that, I was
notified in the gui that there were additional nodes, did I want to add
them.  Initially, I skipped that and went back to the command line as Jason
suggests.  Unfortunately, it could not find any other nodes through his
method, and it didn't work.  Combine that with the warnings that I should
not be using the command line method, and it would be removed in the next
release, I went back to the gui and attempted to add the nodes that way.

Here's where things appeared to go wrong...It showed me two additional
nodes, but ONLY by their -g (private gluster) hostname.  And the ssh
fingerprints were not populated, so it would not let me proceed.  After
messing with this for a bit, I realized that the engine cannot get to the
nodes via the gluster interface (and as far as I knew, it shouldn't).
Working late at night, I let myself "hack it up" a bit, and on the engine
VM, I added /etc/hosts entries for the -g hostnames pointing to the main
IPs.  It then populated the ssh host keys and let me add them in.  Ok, so
things appear to be working..kinda.  I noticed at this point that ALL
aspects of the gui became VERY slow.  Clicking in and typing in any field
felt like I was on ssh over a satellite link.  Everything felt a bit worse
than the early days of vSpherePainfully slow.  but it was still
working, so I pressed on.

I configured gluster storage.  Eventually I was successful, but initially
it would only let me add a "Data" storage domain, the drop-down menu did
NOT contain iso, export, or anything else...  Somehow, on its own, after
leaving and re-entering that tab a few times, iso and export materialized
on their own in the menu, so I was able to finish that setup.

Ok, all looks good.  I wanted to try out his little tip on adding a VM,
too.  I saw "ovirt-imiage-repository" in the "external provid

Re: [ovirt-users] Issue with OVN/OVS and mandatory ovirtmgmt network

[TranceWorldLogic .]

Hi All,

I am also facing same issue (unable to change ovirtmgmt to OVS type).

On git repository, I saw some commit in which added support to switch
network type in host. but there is red cross across those changes.
Would I get to know will this issue get solve in 4.1 release ?

I tried modifying ifcfg-ovirtmgmt and ifcfg-eth0 file to support OVS and
then rebooted m/c.
When m/c got bootup I found that configuration made in ifcfg got
overwritten by vdsm.
Is their any workaround ?

Thanks,

Re: [ovirt-users] Issue with OVN/OVS and mandatory ovirtmgmt network

[Edward Haas]

Guys,

In oVirt, when a host is added to the cluster it must have a NIC/Bond for
management.
Currently, it does not support anything else, unless one uses hooks to fake
things (but I do not recommend it, it will just make things complex and may
collide with other options).
I am not sure if such a feature was already suggested, please check BZ and
if there is no RFE for it, you are welcome to file one.

The OVN part is not related to the management and NIC issue, it assumes the
host is deployed as expected and that Engine can manage it.
It is there to allow OVN to manage VM networks.

Regarding the last message about OVS: Please note that OVN as an external
provider uses OVS, but it is not related to the host networks migrating to
OVS based (From the Linux bridge).
oVirt networking distinguish between host networks and VM networks, the
work on OVS for host networks has started on 4.0 and unfortunately is not
yet finished.
I suggest opening a separate thread about OVS for host networks if more
information is needed (there are some existing threads about it).

Thanks,
Edy.
