Re: Cannot Increase Hosted Engine VM Memory
by Douglas Duckworth
Yes, I do. Gold crown indeed.
It's the "HostedEngine" as seen attached!

Hi Simone
Can I get help with this issue? Still cannot increase memory for Hosted Engine.
From the logs it seams that the engine is trying to hotplug memory to the engine VM which is something it should not happen.
The engine should simply update engine VM configuration in the OVF_STORE and require a reboot of the engine VM.
Quick question, in the VM panel do you see a gold crown symbol on the Engine VM?

No, it's not required.

Use public-signed SSL certs?
by Chris Adams
I installed an SSL cert from a public CA (Let's Encrypt) on my engine,
following this:
https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.2/...
That gets the regular web UI working, but I can't upload an ISO. I
assume that I need to do something with the imageio-proxy service on the
engine, but not sure what... I tried replacing imageio-proxy.cer and
imageio-proxy.key.nopass, but that didn't work.
I'm trying to avoid ever needing to install a special CA cert in
browsers.

reinstallation information
by nikkognt＠gmail.com
Hi,
after a blackout one host of my ovirt not working properly. I tried to Reinstall it but ends with the following error "Failed to install Host ov1. Failed to execute stage 'Closing up': Failed to start service 'vdsmd'." I tried to start manually but it not start .
Now, I would like to reinstall from iso ovirt node.
After I put the host is in maintenance must I remove host from the cluster (Hosts -> host1 -> Remove) or I can reinstall without remove it?
If I remore it from the cluster the network configurations I lose them or not?
My ovirt version is oVirt Engine Version: 4.1.9.1-1.el7.centos.

Spice console very poor performance for Windows 10 vm
by Leo David
Hello Everyone,
Maybe I am something wrong, but spice console seem to be very laggy and
slow for windows 10 vms. I have tried both qxl and qxl-dod drivers, but no
luck so far...
As a notice, the Win 2012R2 vm console is running fine, the problem seems
to only affect Windows 10.
Any ideas, what should I do to sort this out ?
Thank you very much !
Leo

Supporting comments on ovirt-site Blog section
by Roy Golan
It would be very useful to have a comment section on our ovirt site.
It is quite standard to have that on every blog out there, and for a reason
- you get
feedback and conversation around the topic, without going somewhere else
(users list, irc, etc...)
What do we need to do to help the middle man with that?

Re: Gluster VM image Resync Time
by Strahil
By default ovirt uses 'sharding' which splits the files into logical chunks. This greatly reduces healing time, as VM's disk is not always completely overwritten and only the shards that are different will be healed.
Maybe you should change the default shard size.

Any plans for oVirt and SBD fencing (a.k.a. poison pill)
by hunter86_bg＠yahoo.com
Hello Community,
Do you have any idea if SBD fencing mechanism will be implemented in the nearest future?
It will be nice to be able to resset a host just like corosync/pacemaker cluster implementation.

[Users] Problem Creating "oVirtEngine" Machine
by Richie＠HIP
--Apple-Mail=_DF4BF6D1-1F87-4F60-9CF9-070D4D836241

I can't agree with you more. Modifying every box's or Virtual Machine's =
HOSTS file with a FQDN and IP SHOULD work, but in my case it is not. =
There are several reasons I've come to believe could be the problem =
during my trial-and-errors testing and learning.
FIRST - MACHINE IPs.
THe machine's "Names" where not appearing in the Microsoft Active =
Directory DHCP along with their assigned IPs; in other words, the DHCP =
just showed an "Assigned IP", equal to the Linux Machine's IP, with a =
<empty> ('i.e. blank, none, silch, plan old "no-letters-or-numbers") =
"Name" in the "Name" (i.e. machines "network name", or FQDN-value used =
by the Windows AD DNS-service) column. =20
if your IP is is appearing with an <empty> "name", there is no "host =
name" to associate the IP, it makes it difficult to define a FQDN; which =
isn't that useful if we're going to use the HOSTS files in all =
participating machines in an oVirt Installation.
I kept banging my head for three (3) long hours trying to find the =
problem.
In Fedora 18, I could't find where the "network name" of the machine =
could be defined. =20
I tried putting the "Additional Search Domains" and/or "DHCP Client ID" =
in Fedora's 18 Desktop - under "System Settings > Hardware > Network > =
Options > IPv4 Setting"
The DHCP went crazy; showing an "Aberrant-MAC-Address" (i.e. a really =
long-sting value where the machine's MAC address should be), and we knew =
the MAC address as we obtained using "ifconfig" on the machine getting =
it's IP from the DHCP. So we reverted these entries from the =
aforementioned, rebooted, and got an assigned IP, with proper MAC =
address, but still no "Name"
Kept wondering around the "Settings" and seeing which one made sense, =
but what the heck, I went for it. =20
Under "System Settings > System > Details" I found the information about =
GNOME and the machine's hardware. =20
There was a field for "Device Name" that originally had =
"localhost.localdomain"; I changed the value to "ovirtmanager". and =
under "Graphic" changed to "Forced Fallback Mode" to "ON". =20
I also installed all Kerberos libraries and client (i.e. authconfig-gtk, =
authhub, authhub-client, krb5-apple-clents, krb5-auth-dialog, =
krb5-workstation, pam-kcoda, pam-krb5, root-net.krb5) and rebooted
VOILA=85!!! =20
I don;t know if it was the definition of "Device Name" from =
"localhost.localdomain" to "ovirtengine", of the Kerberos libraries =
install, or both. But finally the MS AD DHCP was showing the =
Addigned-IP, the machine "Name" and the proper MAC-address. Regardless, =
setting the machine's "Network Name" under "System Settings > System > =
Details > Device Name", with no explanation of what "Device Name" meant =
or was used for, was the last place I would have imagined this network =
setting could be defined.
NOTE - Somebody has to try the two steps I did together, separately. to =
see which one is the real problem-solver; for me it is working, and "if =
it ain't broke, don't fix it=85"
Now that I have the DHCP / IP thing sorted, I have to do the DNS stuff.
To this point, I've addressed the DHCP and "Network Name" of the =
IP-Lease (required for the DNS to work). This still does't completely =
explain why, by modifying the HOSTS file (allowing be to set and IP and =
non-DNS FQDN). allows me to install the oVirtEngine "as long as I do not =
use default HTTPd service parameters as suggested by the install". By =
using the HOST file to "define" FQDNs, AND NOT using the default HTTPd =
suggested changes, I'm able to install the oVirtEngine (given that I use =
ports 8700 and 8701) to access the "oVirtEngine Welcome Screen", BUT =
NONE of the "oVirt Portals" work=85 YET=85!!!
More to come during the week
