NFS Storage Advice?
by Wesley Stewart
I currently have a NFS server with decent speeds. I get about 200MB/s
write and 400+ MB/s read.
My single node oVirt host has a mirrored SSD store for my Windows 10 VM,
and I have about 3-5 VMs running on the NFS data store.
However, VM/s on the NFS datastore are SLOW. They can write to their own
disk around 10-50 MB/s. However a VM on the mirrored SSD drives can get
150-250 MB/s transfer speed from the same NFS storage (Through NFS mounts).
Does anyone have any suggestions on what I could try to speed up the NFS
storage for the VMs? My single node ovirt box has a 1ft Cat6 crossover
cable plugged directly into my NFS servers 10GB port.
Thanks!

Spice console pixelated noise on display changes
by Mitja Mihelič
Dear all,
We are running the following setup:
ovirt-engine host:
- CentOS release 7.5.1804
- ovirt-engine-4.1.9.1-1.el7.centos.noarch
- spice-html5-0.1.7-1.el7.noarch
We have noticed problems with the Spice console. When it opens and
displays the information presented by the VM's console it is OK at
first. But as soon as any part of the display changes, that part gets
replaced by random pixelated noise.
For example I open the console of a standard CentOS server. When I type
something at the login prompt the text is invisible and random pixels
are displayed at the position of the blinking cursor. Please see
attached screenshot spice-1-login_typing_and_cursor_waiting.png.
Please also see other the attached screenshots.
Login prompt after VM reboot: spice-2-login_after_boot.png
Login prompt after hitting Enter a few times: spice-3-login_2x_enter.png
We have tried and succesfully reproduced the issue on OSX (Chrome, FF,
Safari) and Windows (Chrome, FF).
VNC works fine.
Why would this be happening? Help would be very much appreciated.
Kind regards,
Mitja

update cluster 4.1 to 4.2
by p.staniforth＠leedsbeckett.ac.uk
Hello,
When I try to update my default cluster to 4.2 it fails with
Failed to update Host cluster (User: admin@internal-authz)
I get a lot of errors
ERROR [org.ovirt.engine.core.bll.UpdateVmCommand] (Transaction Reaper Worker 0) [] Transaction rolled-back for command 'org.ovirt.engine.core.bll.UpdateVmCommand'
Thanks,

Understanding JBOD brick configuration
by Jayme
I'm deploying three host Ovirt HCI and I'm a bit confused about how to
configure the glusterFS volumes and bricks in the cockpit.
My three hosts are configured the exact same way physically:
2x250GB SSDs in Raid 1 for OS
2 x 2TB SSD in JBOD which I intend to use for Gluster (devices sda and sdb)
So on Step 3 (Volumes) of gluster deployment I'm leaving the volumes
default (with no arbiter as I want replica 3). So that is creating a
volume for Engine, Data and VMstore
On step 4 (Bricks) I'm choosing jbod and next is where I'm getting
confused. I have to specify the device name and size for each volume. It
appears that I have to break up sda and sdb devices here. I have 4 TB
total between the two JBOD drives but does that mean I can only specify up
to 2TB usable for the data volume (on either sda or sdb) then split the
space on the second 2TB drive between engine and vmstore? If so this seems
like an awful waste of a 2TB drive for use for only engine and vmstore
volumes. With my JBOD configuration of two separate disks per hosts is
there any way I can have a data volume use most of that space say 3.5TB and
the rest goes to engine/vmstore? It was my understanding that glusterFS
would pool all available space together and I could use it however I
wanted. Can I achieve this without putting the 2TB disks in to a raid
configuraiton?
Thanks!

trunked ports
by william.dossett＠gmail.com
Hi,
I setup oVirt a few years back. now that the HCI is real, I am revisiting
it. I have deployed with Gluster, and am now moving on to networking.
I come from a VMware shop and normally we trunk all the network ports
exposing all VLANs to the hosts and place VMs in Portgoups that are tagged
with VLANs.
I did manage to do this years back but I am struggling to get this to work
today. I had pretty limited hardware back then and I thought I installed
using vlan tagging and trunked ports, but I don't see any option to do this
using the glusterfs and hosted engine setup.
Each host has a dual port 10Gb NICs I use one for storage that is connected
to my storage network and one for ovirtmgmt. (I need to add another of
these for redundancy down the road, but no money for that at the moment)
The hosts also have 4 x 1Gb ports. So in lieu of being able to configure
vlan tagging to trunked ports on hosted engine deploy, I am considering
cabling up a 1 Gb port on each in my management services VLAN and when it is
all up and running create another logical network (or several of them as I
think these equate to what is a vlan tagged port group in VMware) with the
10Gb NIC backing for VMs.
Does that sound reasonable? Or if anyone can point me to any docs that
describe how to deploy to a specific VLAN with trunk ports, that would be
nice as well as I won't have to actually go to the office and run additional
cables.
Appreciate any advice
Bill

Do you need to format/mount bricks before deploying HCI?
by Jayme
I'm building a 3 host HCI configuration. I have servers configured and
latest version of oVirt node 4.2 installed. I'm preparing to run the
cockpit hosted engine + glusterFS deploy.
Each of my hosts have two SSDs in JBOD /dev/sda and /dev/sdb
Currently these drives have not been touched, formatted or mounted. Is
this required before continuing with the deploy, or will the deploy script
format and mount the drives accordingly?
Thanks!
