[ovirt-users] Re: Agentless backup solutions

[Douglas Duckworth]

Hi


We are running oVirt 4.2.8.2-1.el7.  Should probably upgrade but it works.

We are backing up the 
engine<https://ovirt.org/documentation/admin-guide/chap-Backups_and_Migration.html>
 every day with dump going to external NFS file system then onto the cloud.  
For VMs we are doing backups within Linux itself using a program called 
Restic<https://github.com/restic/restic> which then sends data to cloud S3 
service.  That runs daily as well.


We also save all configuration data, for applications running on our VMs such 
as Apache, etc, within Ansible.   So we can quickly recreate the VM using 
Ansible, along with any applications, then restore any data, not saved in 
Ansible, such as private PKI keys or PostgreSQL dump, for example, from Restic. 
 Dockerized applications even easier.  There would be some downtime to redeploy 
a new VM but this is acceptable given the constrains of our environment.


I am wondering under what situations has anyone experienced VM corruption?  
This would help me determine if more effort should be invested in snapshotting 
VMs and possibly exporting their disks.  Though as I recall removing snapshots 
from my storage domain would require shutting down the VM, right?

[ovirt-users] Re: Infiniband Usage / Support

[Douglas Duckworth]

You can change the MTU in the network config in oVirt engine.  The management 
portal.   Go to clusters then networks or something like that.  You can then 
modify the MTU.

MTU can also be set manually in network scripts on the host but you need to 
define this in the engine.  At least this is how I got Infiniband working.  I 
can send screenshots on Monday.

Next step.
Assign New network to bond0, oVirt set MTU to 1500, and ... That is all. No 
storage, No IP. I can't change MTU to 2044 or 65520 and can't assign IP to IB

From system perspective i do understand why.
oVirt Creates new bridge using brctl - and brctl didn't support IPoIB, but how 
can i change it back to original config?

Hi Simone

Can I get help with this issue?  Still cannot increase memory for Hosted Engine.

From the logs it seams that the engine is trying to hotplug memory to the 
engine VM which is something it should not happen.
The engine should simply update engine VM configuration in the OVF_STORE and 
require a reboot of the engine VM.
Quick question, in the VM panel do you see a gold crown symbol on the Engine VM?

Hello

Can anyone confirm that the steps for upgrading to 4.3 from 4.2 are the same as 
listed for previous versions?

I reviewed 4.1 to 4.2 which looks straight forward:

https://www.ovirt.org/documentation/upgrade-guide/chap-Upgrading_from_4.1_to_oVirt_4.2.html<https://urldefense.proofpoint.com/v2/url?u=https-3A__www.ovirt.org_documentation_upgrade-2Dguide_chap-2DUpgrading-5Ffrom-5F4.1-5Fto-5FoVirt-5F4.2.html&d=DwMFaQ&c=lb62iw4YL4RFalcE2hQUQealT9-RXrryqt9KZX2qu2s&r=2Fzhh_78OGspKQpl_e-CbhH6xUjnRkaqPFUS2wTJ2cw&m=DKuJsJH4O7THJQtP6lPrqwwKnYWSCaWDWPs5uQnf6bQ&s=pLg04Zja6C8MqI-5NAte38pDSaMClw3_AmUaVUCtxxI&e=>

I am sure nothing will go wrong though we are doing daily backups of the hosted 
engine VM database.

If you are on 4.2.7 I would recommend upgrade the engine to 4.2.8 before 
upgrading to 4.3.
Since in 4.3 we switched from fluentd to rsyslog for the metrics part, with 
4.2.7 you may have some issue if you upgrade hosts to 4.3 before the engine 
gets upgraded.

Hi Simone

Can I get help with this issue?  Still cannot increase memory for Hosted Engine.

From the logs it seams that the engine is trying to hotplug memory to the 
engine VM which is something it should not happen.
The engine should simply update engine VM configuration in the OVF_STORE and 
require a reboot of the engine VM.
Quick question, in the VM panel do you see a gold crown symbol on the Engine VM?

Hi

I opened a BugZilla at https://bugzilla.redhat.com/show_bug.cgi?id=1664777 but 
no steps have been shared on how to resolve.  Does anyone know how this can be 
fixed without destroying the data center and building a new hosted engine?

Hello

I am trying to migrate my hosted-engine VM to another cluster in the same data 
center.  Hosts in both clusters have the same logical networks and storage.  
Yet migrating the VM isn't an option.

To get the hosted-engine VM on the other cluster I started the VM on host in 
that other cluster using "hosted-engine --vm-start."

However HostedEngine still associated with old cluster as shown attached.  So I 
cannot live migrate the VM.  Does anyone know how to resolve?  With other VMs 
one can shut them down then using the "Edit" option.  Though that will not work 
for HostedEngine.

[ovirt-users] Re: migrate hosted-engine vm to another cluster?

[Douglas Duckworth]

Hi

Should I open a Bugzilla to resolve this problem?

Thanks,

Hello

I am trying to migrate my hosted-engine VM to another cluster in the same data 
center.  Hosts in both clusters have the same logical networks and storage.  
Yet migrating the VM isn't an option.

To get the hosted-engine VM on the other cluster I started the VM on host in 
that other cluster using "hosted-engine --vm-start."

However HostedEngine still associated with old cluster as shown attached.  So I 
cannot live migrate the VM.  Does anyone know how to resolve?  With other VMs 
one can shut them down then using the "Edit" option.  Though that will not work 
for HostedEngine.

You cannot assign this role to the host interface directly, but to the

[ovirt-users] Re: losing ib0 connection after activating host

[Douglas Duckworth]

Hi Dominik,

I have added LACP bond network to all hosts and renamed the Hosted Engine using 
"/usr/share/ovirt-engine/setup/bin/ovirt-engine-rename."

However, I am still missing the option to assign Migration and Management 
network roles to this new bond.

Can you advise where I can find this option?

Thanks,

You have to create a new logical network in

and assign this to ib0 in
"Compute > Hosts > hostname > Network Interfaces > Setup Host Networks".
After this you can assign a role to this network in

[ovirt-users] Re: ovirt-engine-extension-aaa-ldap-setup credentials invalid

[Douglas Duckworth]

Thanks!

I set that after completing setup though still cannot login:

2018-08-30 10:42:46,470-04 ERROR

task-5) [] Cannot authenticate user 'me@scu' connecting from '10.0.0.136':

How can I get get more verbose logging?

Yes, indeed!

How can I change this internal Python setting?

[ovirt-users] Re: Turn Off Email Alerts

[Douglas Duckworth]

Thanks for sharing

I may want to do that

Though first I want to understand how the emails are arriving.

I stooped ovirt-engine-notifier.service and postfix.service on all hosts
and the hosted engine.  So how are the email being delivered?  They are not
running senmail so I don't understand what daemon's sending these messages.

[ovirt-users] Re: Turn Off Email Alerts

[Douglas Duckworth]

I agree however we are in testing phase so I make changes a lot.  Therefore
alerts are not presently needed.

So how to I turn them off?

These steps do not work on hosted engine:


me@ovirt-engine[~]$ sudo systemctl stop postfix.service
me@ovirt-engine[~]$ sudo systemctl stop ovirt-engine-notifier.service
me@ovirt-engine[~]$ sudo systemctl status ovirt-engine-notifier.service

I still get an email every time I put a host in maint mode for example.

[ovirt-users] Re: losing ib0 connection after activating host

[Douglas Duckworth]

Sorry, I mean "migration network" for moving live migration traffic.

FDR infiniband much faster than 1Gb network which currently acts as
migration network, vm network, display network, mgmt network, etc.

[ovirt-users] Turn Off Email Alerts

[Douglas Duckworth]

Hi

How do I turn off hosted engine alerts?  We are in a testing phase so these
are not needed.  I have disabled postfix on all hosts as well as stopped
the ovirt notification daemon on the hosted engine.  I kept it running
while putting /dev/null in
/usr/share/ovirt-engine/services/ovirt-engine-notifier/ovirt-engine-notifier.conf
for
mail server.  Yet I still get alerts for every thing done such as putting
hosts in maintenance mode.  Very confusing.

Rebooted the hosted engine VM

Migration now works

Guess that's needed after changing cluster CPU type

[ovirt-users] Re: losing ib0 connection after activating host

[Douglas Duckworth]

Hi Dominik

Yes, the network-script was created by our Ansible role that deploys CentOS
hosts.  It pulls the IP from DNS then templates the script and copies to
host.

I will try this oVirt step then see if it works!

[ovirt-users] losing ib0 connection after activating host

[Douglas Duckworth]

Hi

I keep losing ib0 connection on hypervisor after adding host to engine.
This makes the host not really work since NFS will be mounted over ib0.

I don't really understand why this occurs.

OS:

[root@ovirt-hv2 ~]# cat /etc/redhat-release
CentOS Linux release 7.5.1804 (Core)

Here's the network script:

[root@ovirt-hv2 ~]# cat /etc/sysconfig/network-scripts/ifcfg-ib0
DEVICE=ib0
BOOTPROTO=static
IPADDR=172.16.0.207
NETMASK=255.255.255.0
ONBOOT=yes
ZONE=public

When I try "ifup"

[root@ovirt-hv2 ~]# ifup ib0
Error: Connection activation failed: No suitable device found for this
connection.

The error in syslog:

Aug 22 11:31:50 ovirt-hv2 kernel: IPv4: martian source 172.16.0.87 from
172.16.0.49, on dev ib0

As you can see media state up:

The card is FDR:

The following OFED modules are loaded:

  ib_uverbs
  ib_umad
  ib_ucm
  ib_cm
  ib_core
  mlxfw
  mlx5_fpga_tools

I can add an IP to ib0 using "ip addr" though I need Network Manager to
work with ib0.

[ovirt-users] Re: live migration of hosted engine between two hosts

[Douglas Duckworth]

Thanks!

I am downgrading to an older kernel to see if kdump will work.  My other
hypervisor works fine with 3.10.0-862.9.1.el7 but this host has a newer one.

Sorry for disorganized nature of this thread.

Can you tell me how to get ib0 set as migration network?

Thanks,

[Douglas Duckworth]

OK, after a while this host goes into bad state due to "HA score."  Could
this be due to kdump not being enabled?

[ovirt-users] Re: SSSD on Hosted Engine

[Douglas Duckworth]

FYI,

This allowed SSSD to work on hosted engine at least for system auth

semanage fcontext -a -t net_conf_t '/etc/hosts'

 /sbin/restorecon -v /etc/hosts

sealert -a /var/log/audit/audit.log shows a ton of daemons were unable to
read /etc/hosts...

[ovirt-users] Re: SSSD on Hosted Engine

[Douglas Duckworth]

Yay, I was able to restore nsswitch so things now work.

Anyway that oVirt can use SSSD for web auth?

Per https://ovirt.org/develop/release-management/features/infra/aaa_faq/
there's a bug https://bugzilla.redhat.com/show_bug.cgi?id=829292 that
prevents it from working?

[ovirt-users] SSSD on Hosted Engine

[Douglas Duckworth]

Hi

I am trying to configure sssd on my hosted engine.  Essentially we control
host access in LDAP so I want sssd to read that thus allow my coworkers to
login to hosted engine vm.

For some reason sssd reports backend offline even though it's resolvable,
pingable, with ports open.  I see that it's a SELinux issue which I can
resolve.  After changing to permissive SSSD works.

To have system read sssd database I set hosts line in /etc/nsswitch.conf to:

hosts files sss

Though it seems that I did something bad to /etc/nsswitch.conf as now yum,
ping, etc does not work.

Could someone suggest how to restore this file or could anyone share theirs?

Thanks,

[ovirt-users] Re: live migration of hosted engine between two hosts

[Douglas Duckworth]

Thanks everyone!

During reinstall ran into this error:

Job for kdump.service failed because the control process exited with error
code. See "systemctl status kdump.service" and "journalctl -xe" for details.

I was then able to successfully re-install hypervisor after disabling kdump.

Migration now works

So both hosts have Infiniband.  How can I set that up as Migration
network?  I would rather that ovirtmgmt not be the migration network since
it's only 1Gb vs 56Gb FDR.

[ovirt-users] live migration of hosted engine between two hosts

[Douglas Duckworth]

Hi

I am trying to live migrate my hosted engine between two hosts.

Both hosts are now up.

The hosted engine exists on shared NFS storage mounted on both hypervisors.

Though when I tried to migrate the VM I am told that's not possible.

Could this be since I never defined migration network?  If so I tried doing
that in the oVirt UI as described
https://ovirt.org/documentation/admin-guide/chap-Logical_Networks/ though
many of these options have changed.

Thanks,

[ovirt-users] ovirt 4.2.5.2-1.el7 cannot locate ovirt-host package when trying to add new host

[Douglas Duckworth]

Hi

Do we need to add the ovirt repo on new potential host?  If I don't do that
manually then adding host, via oVirt UI, fails.

The error:

Though if I add https://resources.ovirt.org/pub/yum-repo/ovirt-release42.rpm
on the new host manually then adding the new host succeeds.

[ovirt-users] Re: hosted engine not reachable

[Douglas Duckworth]

To update I opened a bug report
https://bugzilla.redhat.com/show_bug.cgi?id=1618410

One cannot mask firewalld otherwise hosted-engine deploy will fail in this
manner.

Would be nice if a check would tell user to unmask firewalld rather than
fail in this way.

[ovirt-users] Re: hosted engine not reachable

[Douglas Duckworth]

Eventually failed.

I am running CentOS 7.5 on the host.  After re-reading documentation it
seems that my /var partition might not be large enough, as it's only 30GB,
but no warning message indicating that's an issue.

Ok the ansible engine-deploy now seems to be stuck and same step:

[ovirt-users] Re: hosted engine not reachable

[Douglas Duckworth]

Ok

I was now able to get to the step:

Engine replied: DB Up!Welcome to Health Status!

By removing a bad entry from /etc/hosts for ovirt-engine.pbech which
pointed to an IP on the local virtualization network.

Though now when trying to connect to engine during deploy:

[ ERROR ] The VDSM host was found in a failed state. Please check engine
and bootstrap installation logs.

[ ERROR ] Unable to add ovirt-hv1.pbtech to the manager

Then repeating

[ INFO  ] Still waiting for engine to start...

The export / import can only be done when VM down?

I last used oVirt at 3.6 so looking forward to the new features!

[ovirt-users] Re: Live Migration via NFS

[Douglas Duckworth]

Hi Nir

Thanks for clarifying

We can still use NFS as export domain which can be used to move VM once
they're shutdown?

Can GPFS be used to provide shared block storage domain?

Thanks,

[ovirt-users] Live Migration via NFS

[Douglas Duckworth]

Hi

I haven't used oVirt in several years so wanted to ask how live migration
may have changed.

Can NFS facilitate live migration in cluster of two hosts each which have
NFS mounted?

The hosts would have local attached storage which would be the original
location of VMs.

[ovirt-users] GPFS Storage Domains - Live VM Migration Between LocalOnHost Only

[Douglas Duckworth]

Hi

I used RHEV in the past and now that I am in a new role we're considering
oVirt.

I have a few questions:

Does oVirt support network Storage Domains using GPFS?

Does oVirt support live VM Migration of between Hosts that have
"LocalOnHost" (direct attached) Storage Domains only?

Best
Doug
