Host reboot take an awful lot of time
by duparchy＠esrf.fr
KVM host is upgraded then rebooted. It seems OK (ssh available, no particular activity) but it takes an awful lot of time for the manager to acknowledge it and let us activating the host.
This makes the upgrade process of a whole infrastructure (several hosts) very very long.
Is it just us ? (oVirt 4.5 "Oracle" flavor)

Help With CPU Type
by Daniel Martins
Hi There,
Please may you assist me with the below?
I need to remove an oVirt host within a cluster that is using CPU Type Intel Westmere IBRS SSBD Family. Once the host is removed i need to change the CPU type to Intel Broadwell which the remaining hosts Use.
So my question is will there need to be down time on the Virtual machines to change this?

Managing Users with Keycloak WebUI
by Vladislav Solovei
Hello! I have a question about managing users through the Keycloak WebUI. With oVirt 4.5.
Can I do this? Is it the right approach? Or should I avoid doing it? For example, if I want to create a user with 2FA (OTP)

Really weird ! Image IO / browser upload only working on 1 cluster (out of many) - anyone got any advice ? (network access, certs seem fine.)
by morgan cox
One for the mystery van ..
I am running OLVM/ Ovirt 4.5 (engine) - hosts presently mised 4.4.x and 4.5.x - however version doesn't seen to be the issue
We have muliple DC's/Clusters each cluster has 2 hosts and then have access to different fc SAN volumes - each san vol is a sperate storaqe domain
I,e
host 1 + host 2 --> San 1
host 3 + host 4 --> San 2
, etc
SAN connection for the hosts/clusters generally is working fine and I can also upload to any SAN volume using the upload script - /usr/share/doc/python3-ovirt-engine-sdk4/examples/upload_disk.py
However imageio via browser ... We have a major issue.
I am not able to upload (via browser) any files to any storage domain apart from 1... (say San 1)
Yes, I have imported the CA to browser, and All storage domains pass the 'test connection' -> "Connection to ovirt-imageio was successful."
However I can see what the issue is (but not why there is this issue..)
In the upload image section of all domains the available host to use (to piggyback connection) as the same - host 1 + host 2
But those hosts only have access to one SAN not all of them
i.e for San 2 I should be able to choose host 3 + 4 ... (but only host 1/2 are showning in all domains..)
If I use the upload script it uses correct host and successfully upload - but not via browser..
I have checked and /etc/ovirt-imageio/conf.d/60-vdsm.conf is the same for ALL hosts. Certs seem ok all a
I can telnet to all hosts from engine on port 54322
Can anyone give me any ideas how to troubleshoot this ?
Thanks

EOL glusterFS
by Olivier
Hello,
GlusterFS seems to be EOL. At least no more dev from Red Hat, the github doesn't record any move from more than one year. Is there a plan to use another FS on oVirt instead of glusterFS ?
