Safe to go to 7.8 for CentOS based hypervisors?
by Gianluca Cecchi
Hello,
supposing to be already at 4.3.9 level and to have CentOS 7.7 based hosts,
are there any blocking factors to update them to 7.8, just released some
days ago?
Thanks,

NFS storage domain forced to use /exports/data ?
by kelley bryan
Hello
Should the documentation point out that the /exports/data mount point is hard coded in ovirt-hosted-engine-setup-ansible-create_storage_domain.yaml.
I think some Data Centers will want to use a different mount path
or Did I miss a prompt or entry in the Deployment screen for Hosted-engine-deployment?

Unable to import CA certificate list
by Sakari Poussa
Hi,
I am using 4.4 beta4 and not able to add new hosts to the datacenter. Also
"Enroll Certificate" fails.
On nodes, I get the following error message:
libvirtd[20399]: Unable to import CA certificate list
/etc/pki/vdsm/certs/cacert.pem
The root cause is the malformed cert:
$ cat /etc/pki/vdsm/certs/cacert.pem
-----BEGIN CERTIFICATE-----\nMIID XXX
That, is the .pem file is just one long line with \n characters instead of
real newlines. If I convert the \n to real newlines libvirtd starts but
that is not the end solution since other issues surfaces.
The malforming happens when the engine copies (via ansible) the CA cert to
the node(s).
Any ideas what is going on?
Thanks, Sakari

Backup software recommendations
by Colin Coe
Hi all
I'm looking for recommendations for backup software. It needs to handle
physical and virtual Linux and Windows, RHV and Hyper-V.
It doesn't have to be open source and it doesn't have to be free.
The main features we need are:
- disk to disk backups
- inter-site replication with rate limiting
- be able to handle Linux thin volumes (think RHGS)
- support BMR ans granular file / directory restore
- correctly handle Windows VSS
- support RHEL point releases as soon as they are released
I'm as much after "stay away from" as recommendations.
We currently use Arcserve UDP and it is ... well ... sub optimal
Thanks in advance

VM Portal --> Windows SSO
by Andrey Rusakov
Hi,
Resently I configure oVirt, FreeIPA and Windows Guest VM.
I would like to SSO to Windows VM thrue VM portal or Rest API (dowloading spice config) or Admin Port ...
I don't see any login attemps in log file, errors, or ...
I found a lot of docs for SSO setup - it is so simple (Agent, Correct Domain name in login profile ...), But at the end i found that SSO module was deleted from 4.3 agent. Is it true?
The major question - Is it working ?

Gluster deployment fails with missing UUID
by Shareef Jalloq
Hi,
I'm running the gluster deployment flow and am trying to use a second drive
as the gluster volume. It's /dev/sdb on each node and I'm using the JBOD
mode.
I'm seeing the following gluster ansible task fail and a google search
doesn't bring up much.
TASK [gluster.infra/roles/backend_setup : Create volume groups]
****************

stty: standard tty: inappropriate ioctl for device
by Charles Kozler
I'd like to share this with the list because its something that I changed
for convenience, in .bashrc, but had a not so obvious rippling impact on
the ovirt self hosted installer. I could imagine a few others doing this
too and I'd rather save future them hours of google time
Every install failed no matter what and it was always at the SSO step to
revoke token (here:
https://github.com/machacekondra/ansible/blob/71547905fab67a876450f95c9ca...)
and then reissue new token but the engine log yielded different
information. The SSO failure was a red herring

execution: stty: standard input: Inappropriate ioctl for device
I was on the hunt for this for the better part of 2 days or so, because who
else has anything to do during quarantine, wracking my brain and trying
everything to figure out what was going on
Well, it was my own fault
# cat .bashrc | grep -i stty
stty erase ^?
With this set in the .bashrc of the node I was running the installer via
cockpit from, ovirt installer will fail to install
This was set for convenience to have backspace work in vim since at some
point it stopped working for me
Should I file this as a bug? The message generated is more of a warning
then a failure but I do not know the internals of ovirt like that. Commands
still actually execute fine
ovirt-engine(a)192.168.222.84) # ssh 10.0.16.221 "uptime"
root(a)10.0.16.221's password:
stty: standard input: Inappropriate ioctl for device
22:30:01 up 22:45, 2 users, load average: 0.80, 0.62, 0.80
One thing I think should be called out in the docs, and called out very
loud, is that the entire ovirt installer expects a clean 110% machine that
is done right after install and provided and IP and hostname. Its not that
obvious, but it is now
