That's why I asked  about the update.
The update  process renews  somee certificates, and as it wasn't updated  for a 
 long time - now you have  issues.

I hope  someone from the community can assist you.

My recommendations:
1. Check on all hosts  all vdsm.log  and extract the  VMs' xml
2. Get all network's xml

The auth file  is located  at /etc/ovirt-hosted-engine/virsh_auth.conf

The simple alias:
alias virsh='virsh -c 
qemu:///system?authfile=/etc/ovirt-hosted-engine/virsh_auth.conf'

Is enough to play with the toys directly :)
It's quite handy if  you need to play  with the HostedEngine VM :)

I'm not very pleased of this article.
Last time I needed to fix my HostedEngine, I couldn't find anything useful.
Looking into retrospection ,  If I knew  how to attach a rescue media and boot 
from it  - it would take no more than 10 min to fix it - way faster than to 
restore from backup.

There is this document, but as the notice on it states, at least some parts
of it are outdated:

Forwarding this to the infra team, hopefully someone there will contact you

More information:

- the host that ovirt hosted engine is running on is not running libvirtd.
When we attempt to start it, it complains about expired certs and fails.
Any ideas on this new development?

Looks like content for ovirt site:
https://github.com/ovirt/ovirt-site

To get read-only access you can use:

virsh -r list

Without special configuration.

Using read-write access and modifying vms managed by oVirt is asking for
trouble. Should be
used as a last resort if there is no way to control the vm via oVirt.

Subject: [ovirt-users] Hosted Engine stalled and unable to restart

 

Hello,

 

We are on an older version (3.x - cannot be specific as I cannot get my ovirt 
hosted engine up).

 

We experienced a storage failure earlier this evening - the hosted engine was 
originally installed with this storage domain although we have moved all VM's 
and disks off of it.

 

The storage was restored and all the VM's are now running, but the ovirt engine 
is not pinging and is unreachable.

 

I have attempted to locate it on my HV's using 'virsh list --all' but only one 
of those is taking my credentials - all the others fail to authenticate.

 

Is there a way to locate what the credentials are on each HV since the default 
is not working? Additionally, is there any other way to locate the hosted 
engine and restart it directly from a HV?

 

Thank you for your time and consideration.

[ovirt-users] Mirror oVirt content

2020-04-01 Thread adrianquintero 
Hello oVirt Community / infrastructure team,
we would like to get guidance on how to mirror the oVirt content publicly.  We 
replicate content using our own networks so we'd only be pulling the content 
from the oVirt content server from one location in Chicago.

Please advise.

Thank you,

Hello,

 

We are on an older version (3.x - cannot be specific as I cannot get my ovirt 
hosted engine up).

 

We experienced a storage failure earlier this evening - the hosted engine was 
originally installed with this storage domain although we have moved all VM's 
and disks off of it.

 

The storage was restored and all the VM's are now running, but the ovirt engine 
is not pinging and is unreachable.

 

I have attempted to locate it on my HV's using 'virsh list --all' but only one 
of those is taking my credentials - all the others fail to authenticate.

 

Is there a way to locate what the credentials are on each HV since the default 
is not working? Additionally, is there any other way to locate the hosted 
engine and restart it directly from a HV?

 

Thank you for your time and consideration.

So, how would I go about disabling global maintenance when hosted engine isn't 
running?

 

I tried editing /var/lib/ovirt-hosted-engine-ha/ha.conf and setting both values 
to False but that didn't help.

 

local_maintenance=False

I keep running into this error when I try to (re)deploy self-hosted engine.

 

 

# ovirt-hosted-engine-cleanup

# hosted-engine --deploy

...

...

[ INFO  ] TASK [ovirt.hosted_engine_setup : Fail with error description]

[ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "The host 
has been set in non_operational status, deployment errors:   code 9000: Failed 
to verify Power Management configuration for Host physhost01.example.com 
 ,   fix accordingly and re-deploy."}

 

I shut down all of the VM's and detached the storage before cleaning up and 
trying to re-deploy the hosted engine, first time I've run into this particular 
problem.

 

Any help appreciated

 

Brett

[ovirt-users] Re: Failing to redeploy self hosted engine

2020-04-01 Thread Maton, Brett 
No that was the first thing I tried.

I ended up flattening the physical hosts and reinstalling from the OS up.
Then it was simply a case of importing the detached storages domains.

PITA and took a lot longer than anticipated, but at least it's all working
again.

works fine

[ovirt-users] New Issue - Ovirt Status shows '?' or Down for all elements

2020-04-01 Thread Mark Steele 
Yesterday we had a storage crash that caused our hosted engine to stop and
not auto-restart. We manually restarted it and this morning, all elements
are showing a status of either question mark '?' or a red down chevron.

We are running version oVirt Engine Version: 3.5.0.1-1.el6.

We are chasing it down and see this in the log:

2020-04-01 10:15:53,060 WARN
[org.ovirt.engine.core.vdsbroker.VdsManager]
(DefaultQuartzScheduler_Worker-23) Failed to refresh VDS , vds =
e98f8f1d-dd1d-47c4-b039-d6eaaf578317 : hv-06, VDS Network Error,
continuing


Any insight into what might be causing this or the fix would be appreciated.

[ovirt-users] Re: Hosted Engine stalled and unable to restart

2020-04-01 Thread Mark Steele 
Thank you all!

We were able to locate it on HV-02 and restart it using virsh.

This is how we got virsh working on that HV:

Virsh Authorization
If Virsh is set for Auth
If attempting to use any virsh commands and get auth request you will
either need the auth credentials or to create your own.Example:
$ virsh list
Please enter your authentication name: root
Please enter your password:
error: Failed to reconnect to the hypervisor
error: no valid connection
error: authentication failed: authentication failed
Solution
$ saslpasswd2 -a libvirt

[ovirt-users] Re: DR on hyperconverged deployment

2020-04-01 Thread wodel youchi 
Hi,

I re-did the test and it seems that the minimum RPO is one day and if
someone could confirm that would be great

As for the snapshot this time it was synced

Then I tried to test the fail back and I found that the documentation is
not clear :
- it is not clear what is the purpose of the dr-clear playbook
- it is not clear what does mean : put the target volume in read write mode
and source volume in read-only mode
- Do we have to sync back using a new georeplication link from the dr
volume to source volume?
I tried to so, in my first trial I forced the creation of the back
georeplication without deleting the content of the source volume then I
started the replication manually  (I didn't use the checkpoint) and I
stopped the replication once it reached the changelog state, but I couldn't
import the source volume I got the error : volume is not empty

In my second trial I deleted and recreated the source volume from scratch
and the i started the replication back manually at the end I got the error

In my third trial I deleted the source volume and recreated it from scratch
but I replicated back using the check point method and this time the fail
back worked.

 Could someone sheds some light on this?

Thank you
Regards.

group hugetlbfs. Can you have a look?

A workaround, for now: Create the group hugetlbfs, e.g. using:

groupadd -r hugetlbfs

and try engine-setup again.

[ovirt-users] Re: Local network

2020-04-01 Thread Tommaso - Shellrent 

bingo.

the problem was port security, enabled by default on my system.

Thanks a lot for the support!

Port security requires subnets.
Can you please ensure that you used an external network with port 
security explicitly disabled?
In doubt, please create a new external network with port security 
explicitly disabled and try again with the new network?

Hi.

 on engine all seems fine.

on host the command "ovn-sbctl show" is stuck, and with a strace
a se the following error:


connect(5, {sa_family=AF_LOCAL,
sun_path="/var/run/openvswitch/ovnsb_db.sock"}, 37) = -1 ENOENT
(No such file or directory)

.Hello Tommaso,
   on your oVirt engine host run
check the north bridge controller
ovn-nbctl show
this should show a software switch for each ovn logical network
witch any ports that are active( in your case you should have 2)

check the south bridge controller
ovn-sbctl show
this should show the software switch on each host with a geneve
tunnel.

on each host run
ovs-vsctl show
this should show the virtual switch with a geneve tunnel to each
other host and a port for any active vnics

Regards,

Hi to all.

   I'm trying to connect two vm, on the same "local storage"
host, with an internal isolated network.

My setup;

VM A:

  * eth0 with an external ip
  * eth1, with 1922.168.1.1/24

VM B

  * eth0 with an external ip
  * eth1, with 1922.168.1.2/24

the eth1 interfaces are connetter by a network created on
external provider ovirt-network-ovn ,

I've followed the instructions and tried to install Centos 7 with latest stable 
oVirt (4.3.9) and got stuck on a certificate issue.

If manage to install, please let me know.

Atenciosamente,
