[Users] Console and keyboard setup on VNC
Hello all, first post here :-) When using VNC as the console to access the VM I can't use the portuguese keyboard and see special characters. I tried it with VMs running Fedora, CentOS and Debian. If I ssh the VM, everything is correct on the terminal console. Is this a issue from oVirt or from the VNC server running behind (I guess it's the second). Any help?

I figure it has been discussed, but using the word cluster in a google
search of the wiki results in a lot of hits, none of them that I saw that
are to do with clustering the server, just the virtual machine nodes.
it shouldn't be a huge issue to deploy the user portal on another
machine (although current rpm may require the engine).
As of today the RPMs have inter-dependencies, so it is not possible to
deploy only the user portal. We could make the user portal RPM
independent of the rest. As it is just a JavaScript application it could
even be deployed as static content to many web servers. Those servers
would then need to act as proxies for the requests that the user portal
makes to the backend (due to the same origin limitations in GWT), that
is not complicated. However the scalability bottleneck won't be in the
JavaScript application, but in the backend that processes the requests
that it sends, and we don't have any simple way to replicate it at the
moment, that would require many important changes.
Same for webadmin.
Brian, I will try to prepare some instructions on how to deploy the user
portal to a different machine, but it will be a manual process.
juan - i don't remember if you already looked at this or not yet?
I didn't look at this deeply. It may be worth to try to support this
independent deployment of GUI applications for next release. It would
also simplify GUI installation in Fedora.
But the real scalability bottleneck will still be in the backend, and
suporting an active-active cluster requires major changes.
Brian - btw, the user portal is pretty lightweight - its mainly java
script going to the client, and polling lightly on status changes (which
changes if it is in focus on the client (faster polling) or not (slower
polling).
spice also doesn't go through the user portal today.
Brian, the simplest to use multiple web servers for the user portal is
to configure each of them so that they proxy requests to the server
where ovirt-engine is installed. But that won't really make things
scale, as all the work will be performed by the engine server. To scale
a bit it is better to at least let the web server deliver the user
portal application without disturbing the application server. In order
to do this you will need to do the following:
1. Configure the machine where ovirt-engine is installed so that the
application server will accept AJP requests in a network interface
accessible from the rest of web servers. You will need to edit the
/usr/share/ovirt-engine/service/engine-service.xml.in file and make sure
that the AJP connector looks like this:
socket-binding name=ajp port=$getInteger('ENGINE_AJP_PORT')
interface=public/
The important part here is interface=public, the rest may be different
in your version as this has changed recently. Make sure that you only
change the interface.
(Take into account that the AJP protocol has no security or encryption
support -that is why we bind it to localhost by default- so you should
make sure this machine is in a secure network, or use the firewall to
restrict access).
2. Copy the contents of the
/usr/share/ovirt-engine/engine.ear/userportal.war to the web server
where you want to deploy it. I tend to use a tarball for this:
# cd /usr/share/ovirt-engine/engine.ear/userportal.war
# tar cvf userportal.tar *
Then copy/transfer the userportal.tar file to the web servers where you
want to deploy the user portal.
3. For each web server where you want to deploy the user portal copy the
contents of userportal.tar to the web server documents directory (I
assume you are using /var/www/html):
# cd /var/www/html
# mkdir UserPortal
# tar xvf userportal.tar
4. In a normal installation the HTML page hosting the user portal is
generated dynamically, but if you deploy to a web server statically you
are going to need a static version. You can get this from the server
where the engine is installed:
# wget --no-check-certificate
https://ovirt-engine.example.com/UserPortal/org.ovirt.engine.ui.userportal.UserPortal/UserPortal.html
This will create a UserPortal.html file that you should copy to the
directory
/var/www/html/UserPortal/org.ovirt.engine.ui.userportal.UserPortal.
5. Configure your web server so that it will proxy the requests that the
user portal makes to the backend. This can be done creating a
ovirt-userportal.conf file in /etc/httpd/conf.d with a content like this:
