[ovirt-users] Are Ovirt updates nessessary after CVE-2017-5754 CVE-2017-5753 CVE-2017-5715

[Marcel Hanke]

Hi,
besides the kernel and microcode updates are there also updates of ovirt-
engine and vdsm nessessary and if so, is there a timeline when the patches can 
be expected?
If there are Patches nessessary will there also be updates for ovirt 4.1 or 
only 4.2?

Thanks
Marcel

I viewed the engine backup, but the format as-is doesn't give any

I think it's the field 'vm_guid' in the table 'vm_static'.

You can restore the backup on a temp vm somewhere - make sure it has no
access to your hosts so that the engine will not start to manage them -
or just look at the db dump. The backup is a tar file, and you can look
at db dumps inside it using 'pg_restore filename | less'.


The guest UUID is configurable per VM in Edit dialog, you can use
a custom value



Thank you, I was able to get the UUID back!

[ovirt-users] How to install the engine manually?

Hello everybody.

 

I'd like to know if it is possible to install the whole engine using the folder "src" that I can download from here:

 

http://resources.ovirt.org/pub/ovirt-4.2/

 

Would it be possible to install them all executing a Makefile or script?

Thanks in advance.

[ovirt-users] changing Master Storage Domain

[Giorgio Bersano]

Hello,
I've a question regarding Master Storage Domain. I did already search the
net without results so I'm asking here.

In our production setup (ovirt 4.1.7) we have five iSCSI Data Storage
Domains and we unfortunately need to remove the one that is the Master SD.
That's not difficult, I know the procedure as I did it in the past:
- Move every disk belonging to the MSD to another SD
- Put the MSD in maintenance
- Detach it then Remove it

Another SD is automatically selected as Master and everything should be OK
(for the sake of simplicity i did not mention the other operations needed
on the storage array and the hosts to phisically remove the LUN).

The tricky part is I don't want a random choice, I want to choose which SD
becomes the new Master.
Is there any specific procedure to obtain this result?

TIA,
Giorgio.

[ovirt-users] oVirt-Gluster Hyperconvergence: Graceful shutdown and startup

[Bernhard Seidl]

Hi all and a happy new year,

I am just testing oVirt 4.2 using a three node gluster hyperconvergence
and self hosted engine setup. How should this setup be shutdown and
started again? Here is what tried an experienced:

Shutdown:

1. Shutdown all VMs

2. Enable global ha maintenance

3. Wait for all VM

4. Shutdown hosted-engine using "hosted-engine --vm-shutdown"

5. Wait for stopped hosted engine

6. Shutdown all nodes

Startup:

1. Switch on all nodes

2. Start glusterd on all nodes since it does not start by default (is
this a bug?) using "systemctl start glusterd*"*

3. Check volume status using "gluster peer status" and "gluster volume
status all" on one of the nodes

4. Wait for ovrt-ha-agent until "hosted-engine --vm-status" does not
fail anymore printing "The hosted engine configuration has not been
retrieved from shared storage. Please ensure that ovirt-ha-agent is
running and the storage server is reachable."

4. Start hosted engine "hosted-engine --vm-start" on one of the nodes

5. Check status using "hosted-engine --vm-status" and wait until health
reports good

6. Wait until a host got the SPM role

7. Start VMs

Is this the best/correct way?

Kind regards,
Bernhard

Re: [ovirt-users] ovirt 4.1 hosted engine: Resize or Change "hosted-engine" Data Domain

Hi,

we do not have any nice procedure to do that. Moving hosted engine to
a different storage usually involves backup and restore of the engine
database. See for example here:

I've already done something similar in September; see here the full thread:
http://lists.ovirt.org/pipermail/users/2017-September/084411.html

In that case it was more complicated in the sense that vlan change was
involved for ovirtmgmt and I passed through a new cluster.
Now it is more simple, but while on September case the hosts were plain
CentOS hosts, now they are ovirt-node-ng, so my manual ifcfg files
manipulation doesn't fit.

If vdsm-client command is ok I presume it will be something of type:

# vdsm-client Host setupNetworks
vdsm-client: Command Host.setupNetworks with args {} failed:
(code=-32603, message=Attempt to call function: > with arguments:
() error: setupNetworks() takes exactly 4 arguments (1 given))
#

with some sort of json configuration, but it is not clear to me what to give

Can I do the change of ip from the host web cockpit mgmt interface? I
set/change the ip and then eventually reboot the server to see if it works?

[ovirt-users] ovirt 4.1 hosted engine: Resize or Change "hosted-engine" Data Domain

hi at all,

We have the "hosted engine" Data domain on a FC LUN too big for only the

hosted-engine vm on this new LUN and destroy old one ...

Is there any official workflow or how to to do this operation? Or, someone
can  guide me?

Re: [ovirt-users] Suggestions on changing hosts' network

[Marcin Mirecki]

Hello Gianluca,

Add/remove would probably be the simplest way to go.
The procedure would be:
- take host to maintenance
- remove host
- use vdsm-cient to change the ip of ovirtmgmt
- add the host again

Just changing the dns configuration sounds quite interesting.
I suppose the host certificates should be ok if the host was added by
hostname.
