Bad libvirt-spice certificate - regenerate?
by Chris Adams
I have an oVirt 4.1 cluster that was initially installed with 3.5 in
2014. The SSL certificates on the physical hosts in
/etc/pki/vdsm/libvirt-spice have a problem - the "not before" date is
invalid (it doesn't include a time zone), and so I can't connect to VM
consoles from a client with OpenSSL 1.1.0i (up to date Fedora 27).
How can I regenerate these certificates?
Also, I noticed they expire next year - is that expiration handled
automatically?

Error when running hosted-engine deploy on system with bond of bonds
by Ben Webber
Hi,
I'm trying to set up ovirt using the hosted-engine --deploy command on CentOS7, but am encountering an error. I am running a slightly unusual network configuration. I have two fairly basic non stacked gigabit switches with port channels connecting the two switches together. I have a lacp bond from the host consisting of 4 ports to each switch (bond1 and bond2). I have then created an active-backup bond (bond0) using the two lacp bonds as slaves in the hope to create ha at the switch layer using my basic switches. There is then a VLAN (101) on bond0.
This network configuration runs fine on the host, however, when run, after a short while, the hosted-engine --deploy command outputs the following error:
...
[ INFO ] TASK [Force host-deploy in offline mode]
[ INFO ] ok: [localhost]
[ INFO ] TASK [Add host]
[ INFO ] changed: [localhost]
[ INFO ] TASK [Wait for the host to be up]
[ INFO ] ok: [localhost]
[ INFO ] TASK [Check host status]
[ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "The host has been set in non_operational status, please check engine logs, fix accordingly and re-deploy.\n"}
...
Looking in /var/log/ovirt-engine/engine.log on the machine created, I can see the following errors logged:
...

...
It looks like when HostSetupNetworksVDS is run, it is checking that the slave interfaces to the bonds are physical network devices and being as the slaves of bond0 are bond1 and bond2, rather than physical devices, it then throws the error Unknown nics in: ['bond1', 'bond2'].
Is there anything I can do or any configuration that I can put anywhere to make it work with this "stacked bond" configuration or does ovirt just not work when bonds are set up like this?
Thanks in advance,
Ben

Failed to lock byte 100 - when booting VM with attached CD

I have found recently I can't boot any VMs which have a CD attached to it.
I get the following error.

I have tried relaxing the permissions on the iSO NFS share and even removed
the iSO domain and added a new one, but I still get the problem.

iso domain don't list available images
by Nathanaël Blanchet
Hello,
I detached an existing iso domain from an other ovirt instance and
attached it to on a fresh 4.2 install, but no images are available. Is
it a known bug?

Unable to mount CephFS as POSIX Compliant FS
by ryan.terpstra＠gmail.com
I have a ceph filesystem that I can manually mount on my ovirt host.
[root@ovirt121 ~]# mount -t ceph ceph01:/ /mnt -o name=admin,secret=<secret removed for security>
[root@ovirt121 ~]# touch /mnt/test
works great! Then I umount that filesystem and attempt to add storage domain in ovirt engine. Settings:
Storage type: POSIX compliant FS
Host to use: ovirt121
name: cephdata
Path: ceph01:/
vfs type: ceph
mount options: name=admin,secret=<secret removed for security>
In the oVirt web UI I get a "General Exception" error. On the host I see this in vdsm.log:

Any thoughts?
oVirt version is 4.2.6.4-1.el7, running on CentOS 7 18.05.

no space left to upgrade hosted-engine
by Nathanaël Blanchet
I've deployed and hosted-engine with the hosted-engine provided appliance.
When runing hosted-engine --upgrade-appliance on one host, it tells me
"If your engine VM is already based on el7 you can also simply upgrade
the engine there."
So I launched a yum update on the hosted-engine, but it complains there
is no space left on /

Is the only way is to deploy the new appliance?

ODL and Openstack issue
by Soujanya Bargavi
I am running one controller and one compute node. Controller node is running both ODL and OpenStack. I created tenants, underthem i created networks and launched instances on them. All is see on ODL web GUI is 3 swithces, and I guess those are br-int and br-ex of controller and br-int of compute and the links are missing too. Is there anyway where I can see my whole OpenStack https://goo.gl/6CgufL topology on ODL GUI with the links?
