This is the error that fails you. I have a pending patch to make this more
visible in the log [1], need to find time to verify it...

Does this happen on a clean machine? Perhaps 'engine-cleanup' after such
a failed restore is not enough. Please try reinstalling the OS and trying
again.

If it's not an important machine (test/dev/etc), this will probably be
enough, as a faster replacement for a full OS reinstall:

engine-cleanup
systemctl stop postgresql
systemctl stop rh-postgresql95-postgresql
rm -rf /var/lib/pgsql/data /var/opt/rh/rh-postgresql95/lib/pgsql/data

Then try restore again.

Adding also Eli. Eli - perhaps we need to patch engine-backup to ignore
also this error? I think the minimal flow to reproduce is:

engine-setup
engine-backup --mode=backup --file=f1 --log=l1
engine-cleanup
engine-backup --mode=restore --file=f1 --provision-db
--provision-dwh-db --log=l2

Didn't try this myself.

[ovirt-users] Failed to verify Power Management configuration for Host xxxxxxxxx

[Sakhi Hadebe]

Hi,

I am installing the ovirt cluster of 3 server machines. With the hosted
engine vm running on one of the servers.

I have been struggling to enable Power management. On the Administration it
shows enabled and not editable.

The error it show is:

Error while executing action:

ovirt-host.example.co.za:

   - Cannot edit Host. Power Management is enabled for Host but no Agent
   type selected.


​Please assist.​

Re: [ovirt-users] Power management - oVirt 4,2

[Terry hey]

Dear Martin,
Thank you so much!
It works!
I found that IPMI is disable by default setting.
When i enable it and run fence_ilo4 command, it showed that status is ON.

[root@XX~]# ​fence_ilo4 -a X -l  -p X -v -o status
Executing: /usr/bin/ipmitool -I lanplus -H X -p 623 -U X -P X
-L ADMINISTRATOR chassis power status

0 Chassis Power is on


Status: ON
[root@XX~]#

Thank you so much again!

Terry

I use Bareos for backup.  It is open source.

[Maton, Brett]

You could look at https://github.com/openbacchus/bacchus to automate ovirt
vm backups.

You'd still need to do 'something' to move the vm images from the export
domain to your tape device though.

Hi and welcome to oVirt community! I haven't tested the Ubuntu installation

If you try to install oVirt on Ubuntu please help updating the website with

A paused VM can't be migrated, since there are no guarantees about the
storage state.  As the VMs were paused under erroneous (rather than
controlled such as putting the host into maintenance) situation,
migration policy can't help here.

But highly available VMs can be restarted on another host automatically.
Do you have VM lease enabled for the highly available VM in High
Availability settings?  With a lease, Engine should be able to restart
the VM elsewhere after a while, without it Engine can't do that since
there is danger of resuming the VM on the original host, resulting in
multiple instances of the same VM running at the same time.

VMs without high availability must be restarted manually (unless storage
domain becomes available again).

HTH,
Milan

Can you please provide the output of the following query in your database:

select type, device, address, alias, is_managed, is_plugged from vm_device
where vm_id in (select vm_guid from vm_static where vm_name='');

where  is the name of one of the VMs you can't start because of
that NPE?

[ovirt-users] Installing on ubuntu

[Anastasiya Ruzhanskaya]

Hello!
I am new to oVirt. I want to install it on Ubuntu ( oVirt-Engine) , as I do
this for testing for my diploma at university and don't have too much space
on my computer for hundreds of VMs.
What is the status now? I looked on what is written on the site, is it
still true and it can be done through all the hacks listed there?
Thank you.

[ovirt-users] Backup & Restore

[suporte]

Hi, 

I'm testing backup & restore on Ovirt 4.2. 
I follow this doc 
https://www.ovirt.org/documentation/admin-guide/chap-Backups_and_Migration/ 
Try to restore to a fresh installation but always get this error message: 

restore-permissions 
Preparing to restore: 
- Unpacking file 'back_file' 
Restoring: 
- Files 
Provisioning PostgreSQL users/databases: 
- user 'engine', database 'engine' 
Restoring: 
FATAL: Can't connect to database 'ovirt_engine_history'. Please see 
'/usr/bin/engine-backup --help'. 

On the live engine I run # engine-backup --scope=all --mode=backup 
--file=file_name --log=log_file_name 

And try to restore on a fresh installation: 
# engine-backup --mode=restore --file=file_name --log=log_file_name 
--provision-db --restore-permissions 

Any Idea? 

Thanks

Re: [ovirt-users] Network and VLANs

[Gabriel Stein]

Hi!

Well, the problem starts here:
https://bugzilla.redhat.com/show_bug.cgi?id=1528906

This is a solved marked, but it isn't.

This is what still happens on some servers from us:
https://bugzilla.redhat.com/show_bug.cgi?id=1540463

I have four servers, I updated all hosts on the newest state from
ovirt(4.2.1) and just for two servers worked. For other two doesn't works.
The packages seems to be the same versions on all servers, for the
"working" and  "not working".

The question about oVirt Networking was my curiosity, if I can solve this
problem using another way/workaround(or even a officiall way from ovirt).

If you need more info, I give all the info that you need or I can even
create a bugzilla ticket for that.

Thanks!

All the best,

Gabriel

There is no better way, management network cannot be changed once there are

Hello,

I don't see how is the bug related to your problem, could you elaborate
please? It seems to be fixed now.

Is there any other problem with Setup Networks other than the bug?

oVirt does not support Virtual Switch neither Network Stack, there is an
experimental support of Open vSwitch and OVN though.

[ovirt-users] Failure to upgrade Cluster Compatibility Version

[Jonathan Mathews]

I have been upgrading my oVirt platform from 3.4 and I am trying to get to
4.2.

I have managed to get the platform to 3.6, but need to upgrade the Cluster
Compatibility Version.

When I select 3.6 in the Cluster Compatibility Version and select OK, it
highlights Compatibility Version in red, (image attached).

There are no errors been displayed on screen, or in
the /var/log/ovirt-engine/engine.log file.

Please let me know if I am missing something and how I can resolve this?

[ovirt-users] VM paused rather than migrate to another hosts

[Terry hey]

Dear all,
I am testing iSCSI bonding failover test on oVirt, but i observed that VM
were paused and did not migrate to another host. Please see the details as
follows.

I have two hypervisors. Since they are running iLO 5 and oVirt 4.2 cannot
support iLO 5, thus i cannot setup power management.

For the cluster setting, I set "Migrate Virtual Machines" under the
Migration Policy.

For each hypervisor, I bonded two iSCSI interface as bond 1.

I created one Virtual machine and enable high availability on it.
Also, I created one Virtual machine and did not enable high availability on
it.

When i shutdown one of the iSCSI interface, nothing happened.
But when i shutdown both iSCSI interface, VM in that hosts were paused and
did not migrate to another hosts. Is this behavior normal or i miss
something?

Thank you all of you.

Terry Hung

 Dear Martin,

 Thank you for helping me. To answer your question,
 1. Does the Test in Edit fence agent dialog work​?
 Ans: it shows that "Test failed: Internal JSON-RPC error"

 Regardless the fail result, i press "OK" to enable power management.
 There are four event log appear in "Events"
 The follwing are the log in
 "Event""
 Host host01 configuration was updated by admin@internal-authz.
 Kdump integration is enabled for host hostv01, but kdump is not
 configured properly on host.
 Health check on Host host01 indicates that future attempts to Stop this
 host using Power-Management are expected to fail.
 Health check on Host host01 indicates that future attempts to Start
 this host using Power-Management are expected to fail.

 2. If not could you please try to install fence-agents-all package on
 different host and execute?
 Ans: It just shows "Connection timed out".

 So, does it means that it is not support iLo5 now or i configure
 wrongly?

 Terry

​I haven't seen this hardware, but generally there are 2 possibilities:

1. Withing your SuperBlade management you need to specify unique IP address
for IPMI interface of each host

2. If 1. is not possible, but you have other identification of a host, then
you can try to pass that value using '-n' option on command line or
'plug=XXX' in Options field of a Fence Agent in webadmin

​This is completely different protocol (HTTP) using a browser,  it's
independent of IPMI.

Are you sure that some firewall doesn't block access to the IPMI interface?
Are you executing the command from different host than the host which you
want access the IPMI interface of?
​
​If above is not an issue, then please login to iLO5 management using a
browser and check if IPMI interface is enabled according to your iLO5
documentation

​623 is the default IPMI port

 Hi Terry,

 from the error message below I'd say that you are either not using
 correct IP address of iLO5 interface or you haven't enabled remote access
 to your iLO5 interface.
 According to [1] iLO5 should fully IPMI compatible. So are you sure
 that you enabled the remote access to your iLO5 address in iLO5 management?
 Please consult [1] how to enable everything and use a user with at
 least Operator privileges.

 Regards

 Martin
