You should first come up with something that works when you try it
manually, then try adapting that to the hook's syntax.

I guess you refer above to libvirt xml. This isn't strictly
related to qemu, although in practice most usage of libvirt
is with qemu.

If you have a working libvirt vm, with the options you need,
simply check how it translated your xml to qemu's command line.
You can see this either in its logs, or using ps.

Re: [ovirt-users] Host cannot connect to hosted storage domain

[Alexander Witte]

OK after a host reboot I was able to get the Engine VM up again and into the 
Web interface.  Although continually when I try a second host to the datacenter 
within oVirt I run into the error:

"Host mennode2 cannot access the Storage Domain(s) hosted_storage attached to 
the Data Center Train1.  Setting Host state to Non Operational."

Note:  I can successfully read (and mount) the NFS exports oVirt is complaining 
about:

[root@mennode2 ~]# showmount -e menmaster.traindemo.local
Export list for menmaster.traindemo.local:
/shares *
/shares/exports *
/shares/data*
/shares/isos*
[root@mennode2 ~]#

[root@mennode2 tmp]# mount -t nfs menmaster.traindemo.local:/shares test
[root@mennode2 tmp]# cd test
[root@mennode2 test]# ls
7d18ff24-57a3-4b4a-9934-0263191fe2e4  data  __DIRECT_IO_TEST__  exports  isos
[root@mennode2 test]#

One thing I DO notice is the path of my exports is the difference in the path 
for the hosted_storage domain.  I wonder if the second host would have issues 
resolving this?

Data. ==> menmaster.traindemo.local:/shares/data
Export  ==> menmaster.traindemo.local:/shares/exports
Hosted_storage. ==> localhost:/shares
ISO. ==> menmaster.traindemo.local:/shares/exports


Below I have copied exports from the VDSM and OVIRT-ENGINE log and have copied 
the output of the hosted-engine.conf file.  Any help in pinpointing the source 
of the problem is greatly appreciated!!

[ovirt-users] Host cannot connect to hosted storage domain

[Alexander Witte]

Hi!

Question hopefully someone can help me out with:

In my Self Hosted Engine environment, the local storage domain DATA (NFS) that 
was created with the self engine installation has been configured as 
localhost:/shares

I suspect this is preventing me from adding any additional hosts to the oVirt 
Datacenter as I am receiving a VDSM error that I cannot mount that domain.  I 
think since the domain is set as localhost it cannot be resolved correct by any 
additional hosts...?  The ISO, Data(Master) and EXPORT domains are set as 
FQDN:/shares/iso and I am not seeing problems specific to them.

I am curious what the correct procedure is to change this hosted engine storage 
domain path from localhost:/shares to FQDN:/shares ?  I have attempted this:

1) Put hosted engine in Global Maintenance Mode
2) Shutdown hosted engine
3) edit the /etc/ovirt-hosted-engine/hosted-engine.conf file file and change:
storage=10.0.0.223:/shares   to
storage=menmaster.traindemo.local:/shares
4) Restart hosted engine

Although I’m not having any luck restarting the hosted engine after and running 
a journalctl -u on the overt-ha-agent service is giving me this:

[ovirt-users] iSCSI VLAN host connections - bond or multipath & IPv6

[Ben Bradley]

Hi All

I'm looking to add a new host to my oVirt lab installation.
I'm going to share out some LVs from a separate box over iSCSI and will 
hook the new host up to that.
I have 2 NICs on the storage host and 2 NICs on the new Ovirt host to 
dedicate to the iSCSI traffic.
I also have 2 separate switches so I'm looking for redundancy here. Both 
iSCSI host and oVirt host plugged into both switches.


If this was non-iSCSI traffic and without oVirt I would create bonded 
interfaces in active-backup mode and layer the VLANs on top of that.


But for iSCSI traffic without oVirt involved I wouldn't bother with a 
bond and just use multipath.


From scanning the oVirt docs it looks like there is an option to have 
oVirt configure iSCSI multipathing.


So what's the best/most-supported option for oVirt?
Manually create active-backup bonds so oVirt just sees a single storage 
link between host and storage?
Or leave them as separate interfaces on each side and use oVirt's 
multipath/bonding?


Also I quite like the idea of using IPv6 for the iSCSI VLAN, purely down 
to the fact I could use link-local addressing and not have to worry 
about setting up static IPv4 addresses or DHCP. Is IPv6 iSCSI supported 
by oVirt?


Thanks, Ben

Re: [ovirt-users] Qemu prevents vm from starting up properly

[M R]

Hello!

Thank you very much! I had misunderstood how it was suppose to be
written in qemu_cmdline. There was a typo in syntax and error log
revealed it. It is working IF I use ["-spice",
"tls-ciphers=DES-CBC3-SHA"].
So I believe that installation is correctly done.

Though, my problem still exists.
This is what I have been trying to use for qemu_cmdline:
["-cpu", "kvm=off, hv_vendor_id=sometext"]
It does not work and most likely is incorrectly written.

I understood that qemu commands are often exported into xml files and
the command I'm trying to write is the following:



  


  



How do I write this in custom properties for qemu_cmdline?


best regards

Mikko

I will try this way.
Normally in my setups the ip on the mgmt network of the host is also the ip
corresponding to its hostname
When I delete a host from engine, what happens in relation to its network
files in /etc/sysconfig/network-scripts/ directory and the contents of
/var/lib/vdsm/ directory and its subdirectories?

Re: [ovirt-users] libvirt: XML-RPC error : authentication failed: Failed to start SASL

[VONDRA Alain]

Hello,
I have exactly the same problem after an upgrade from CentOS 7.3 to 7.4, but I 
don’t want to plan now the migration to oVirt 4.x.
Can you help me to correct the bug and keep oVirt 3.6 for a few months ?
It really seems to be a modification in libvirt authentication because when I 
comment out

After hours of struggle, I removed all the hosts.
Installed a fresh centos 6.x on a host. Now it works like a charm.

I will install a fresh ovirt 4.x, and start migration my vm's on new centos 7.4 
hosts.

The only supported way seems exporting/importing vm's for different ovirt 
engines. I wish  I had plain  qcow2 images to copy...


You could detach and attach a whole storage domain.

Unfortunately no, which is a bug, it should also store any column size changes 
but for some reason it doesn't remember those either. I think there is a bug 
open on those but not sure.

[ovirt-users] resizing and reordering column in webui

[Nathanaël Blanchet]

Webui currently usefully allows us to reorder columns by right clicking.

Is there a way to keep the wanted configuration for next sessions?

Original situation was:

1 DC
1 Cluster: CLA with 2 hosts: host1 and host2
ovirtmgmt defined on vlan10

engine is an external server on VLAN5 that can reach VLAN10 of hosts
So far so good

Need to add another host that is in another physical server room. Here
VLAN10 is not present, so I cannot set ovirtmgmt
If I understand correctly, the VLAN assigned to ovirtmgmt is a DC property:
I cannot have different vlans assigned to ovirtmgmt in different clusters
of the same DC, correct?

So the path:
Create a second cluster CLB and define on it the logical network ovirtmgmt2
on VLAN20 and set it as the mgmt network for that cluster
Add the new host host3 to CLB.

So far so good: the engine on VLAN5 is able to manage the hosts of CLA ad
CLB with their mgmt networks in VLAN10 and VLAN20

Now it is decided to create a new VLAN30 that is transportable across the
the 2 physical locations and to have host1, host2, host3 to be part of a
new CLC cluster where the mgmt network is now on VLAN30

Can I simplify operations, as many VMs are already in place in CLA and CLB?
So the question arises:

the 3 hosts were added originally using their dns hostname and not their IP
address.
Can I change my dns settings so that the engine resolves the hostnames with
the new IPs and change vlan of ovirtmgmt?

And if I decide to start from scratch with this new cluster CLC on VLAN30,
can I retain my old 3 hostnames (resolving to their new IPs)? How?

Hope I was able to clarify a bit the scenario

Re: [ovirt-users] Renaming or deleting ovirtmgmt

[Michael Burman]

I was referring to situation in which the host was there before, but you
need to re-install it to the new cluster with the new management network.

No package removing is needed at all. Why would you do steps 2-4? no need.
Step 5 should work.

I'm not sure i understand what you mean by ' still I cannot remove the
default ovirtmgmt network from that cluster'??
Do you want to detach it from the cluster?
Do you want to remove it from the DC?
Note that you can change the management network role only if the cluster
has no hosts in it.

Re: [ovirt-users] changing ip of host and its ovirtmgmt vlan

[Michael Burman]

Hello Gianluca,

Not sure i fully understood, but, if the host's IP has changes and the vlan
then the correct flow will be:

1) Remove the host
2) Edit the management network with vlan tag - the vlan you need/want
3) Add/install the host - make sure you using the correct/new IP(if using
IP) or the correct FQDN(if has changed).

Note that doing things manually on the host such as changing ovirtmgmt's
configuration without the engine or vdsm may cause problems and will not
persist the changes during reboots. If the host's IP has changed or it's
FQDN then you must install the host again.

Cheers)

OK.
But what if the hosts already existed before?
Can I
1) delete host from engine gui
2) remove ovirt packages from host
3) verify also /var/lib/vdsm is removed
4) reboot host and verify all ok as a standalone server
5) add the host to the engine
Will step 5) have problems because y host is sort-of-already-known by the
engine before?

Also, is it expected that if I set another network as mgmt one for a
cluster, still I cannot remove the default ovirtmgmt network from that
cluster?

Re: [ovirt-users] Renaming or deleting ovirtmgmt

[Michael Burman]

Hello Gianluca,

This is not the right flow. If you would like to have any other network in
your cluster as the management network, then you need to create it as the
management network of the cluster and then add hosts to the cluster, then
the new network which was defined as the management network of the cluster
will be the management network of the host/s in the cluster.

The correct flow will be :
1) Create new network for example - 'net1-mgmt'
2) Give 'net1-mgmt'  a management role via manage networks, it can be done
via networks>clusters flow or via Cluster>logical networks flow(note that
management network must be required and attached)
3) Create cluster and choose 'net1-mgmt' as the management network of the
cluster
3) Add/install the host in the cluster

See also -
https://www.ovirt.org/develop/release-management/features/network/management-network-as-a-role/
It's a network feature since 3.6

Cheers)

Hello!

I did check logs from hosts, but didnt notice anything that would help me.
I can copy paste logs later.

I was not trying to get qemu crash vm.
I'm trying to add new functionalities with qemu.

I wasnt sure if my syntax was correct, so I copy pasted the example command
for spice from that website. And it still behaves similarly.

My conclusion is that qemu cmdline is setup wrong or it's not working at
all. But I dont know how to check that.

It looks good, you just miss ", right after eth0, so it should be:

myNicList: [ { nic_name: "eth0", nic_boot_protocol: "dhcp",
nic_on_boot: "true"},{ nic_name: "eth1", nic_boot_protocol: "dhcp",
nic_on_boot: "true"} ]

Also you can pass it as follows(could be more readable):

  myNicList:
  - nic_name: eth0
nic_boot_protocol: dhcp
nic_on_boot: true
  - nic_name: eth1
nic_boot_protocol: dhcp
nic_on_boot: true

If you intended, with the params you passed, to make qemu fail, for whatever
reason (debugging qemu?), then it's not a bug :-) Otherwise, it is, but we
can't know where.

[ovirt-users] Renaming or deleting ovirtmgmt

[Gianluca Cecchi]

Hello,
I notice that in a cluster I can create a new network and then select it as
the Management network, but at the same time the default "ovirtmgmt"
logical network in "Manage Networks" is always checked as both as "Assign"
and "Required" and also grayed so that I cannot change anything of it...
and any host in this cluster must have ovirtmgmt even if it doesn't use it
at all..

Is there any RFE to change this model?
So for example to be able to change its name or delete it after we have
defined a new network as management one.
It seems something similar to the concept of the"Default" DC that now we
can finally rename and /or delete

[ovirt-users] changing ip of host and its ovirtmgmt vlan

[Gianluca Cecchi]

Hello,
an host not maintained by me was modified so that its mgmt network had
become ovirtmgmntZ2Z3.
Originally the host had been added into engine with its hostname and not
its ip and this simplifies things.
So a dns entry change was done while the host was in maintenance
(as far as I have understood...)
The guy changed the /etc/sysconfig/netowrk-scripts/ files and apparently it
was activated ok, but when host rebooted the config was reverted due to
persistence of vdsm.

As he had urgence for this host to become operational again, in the mean
time I worked like this, having now a working host:

- modified /etc/sysconfig/network/scripts files with the new required
configuration
- modified files under /var/lib/vdsm/persistence/netconf/nets/
eg the file ovirtmgmntZ2Z3 with its ip and vlan correct information

sync

then power off / power on host

The host comes up good and as it had been peviously put into maintenance,
it was able to be activated and power on some VMs.

Can I consider this workflow ok or is there any ip/network information of
the host stored into engine db or other parts on engine or hosts?

I have then a question for the ovirtmgmt logical network itself, but I will
open a new thread for it...

Thanks in advance,
Gianluca

Re: [ovirt-users] Preventing VM's from starting on specific Hosts

[Martin Sivak]

Hi,

> This is a rather old release and we encourage everyone to upgrade.

Labels only support presence check (a host with label can host
labelled VMs). We currently do not have rules for the absence of label
(a VM with no label can still run on a labelled host).

This is not a hard RFE to do for Affinity groups, but we would need
proper request for it in bugzilla.

The current implementation expects a custom label / affinity group
management service that maintains rules like this over REST.

[ovirt-users] Qemu prevents vm from starting up properly

[M R]

Hello!

I have followed instructions in https://www.ovirt.org/
develop/developer-guide/vdsm/hook/qemucmdline/

After adding any command for qemu cmdline, vm will try to start, but will
immediately shutdown.

Is this a bug? or is the information in the link insufficient?
If it would be possible to confirm this and if there's a way to fix, I
would really like to have step by step guide of how to get this working.

Correct.

We built dwh 4.1.6 for oVirt 4.1.6, then needed to build again
to include another bugfix, wanted to build 4.1.6.1, but:

>>

... this caused the above bug.

So we fixed the bug, but only in master branch (4.2), and
decided to bump dwh to 4.1.7.

You can see the various patches in the "External Trackers".

Note that while I do not think we had such cases in the past,
we did have many opposite ones - where dwh didn't require a new
build for some release of oVirt, so had a _lower_ version.

Hi Maxence,

It is hard to work using your pasted log, and I'm not sure about stuff you
omitted from the log.

Please attach complete logs from the time you started the vm.
/var/log/vdsm/vdsm.log
/var/log/libvirt/qemu/vdi-admin.log
(vm name taken from the domain xml you posted)

Also, can you access this disk using rbd command line? you will need to
place
ceph secret in /etc/ceph on the host to test this.

You can also file ovirt bug, will make it easier to collect logs and track
this issue.

Re: [ovirt-users] Is this guide still valid?data-warehouse

[Shirly Radco]

Hello Arman,

Reports was deprecated in 4.0.

DWH is now installed by default with oVirt engine.
You can refer to https://www.ovirt.org/documentation/how-to/reports/dwh/

You can change its scale to save longer period of time if you want
https://www.ovirt.org/documentation/data-warehouse/Changing_the_Data_Warehouse_Sampling_Scale/
and attach a reports solution that supports sql.

I'll update the docs with the information about reports and fix the links.

Thank you for reaching out on this issue.

We are currently also working on adding oVirt Metrics solution that you can
read about at
https://www.ovirt.org/develop/release-management/features/metrics/metrics-store/
It is still in development stages.

[ovirt-users] ansible ovirt_vms parameter cloud_init_nics

Hi,

I was trying to initialize more than one nic via cloud init using ansible
as shown below

vars:

"true"},{ nic_name: "eth0, nic_boot_protocol: "dhcp", nic_on_boot: "true"} ]

ovirt_vms:
   auth: "{{ ovirt_auth }}"
   name: test
   ...
   cloud_init_nics : "{{ myNicList }}"

Here I am getting error object is type none.
When I tired to debug ovirt_vms module it showed me below outpu:

   cloud_init_nics: [
   {},
   {}
   ]

My quesion is, how can I pass list of dictionary in ansible to ovirt_vms

well, yes, but you can not multiselect 20 snapshots from 10 different VMs

There is no promise, but we are not dropping it at the moment. As long it's
there, old (3.6.x) ovirt-shell should continue to work. We do not maintain
either though.
Ansible seems to be a great and powerful replacement to ovirt-shell.
Another recommendation I can give is ovirtcmd[1], though I have not tried
it myself, I've looked at the code and it looks good.
