Getting GUI to work with Xen PVMs

Getting GUI to work with Xen PVMs

[Priya]

[-- Attachment #1.1: Type: text/plain, Size: 3302 bytes --]

All,

I am working with Xen 3.0 (I think, though can someone please tell me how I
could verify this!)

I want to install a couple of PVM which I could access with a X-terminal. (I
don't know if I am using the correct terminology here, so I will elaborate:
I want to start my PVM, ssh to them using the -X option [ssh -X user@pvm_ip]
from another machine, and be able to run a command like "glxgears", so that
a pop up window showing the gears-animation shows up and the console prints
the FPS information).

At this point, I already have a PVM installed running a guest OS with kernel
2.6.24-16-xen. However when I try to install "nvidia-glx" for the glxgears
API I get the following error:

----------------

Do I indeed need to install nvidia-glx on my PVM ?
Any advice would be helpful!

glxgears is a demo of OpenGL. if you don't need 3d, use another test,
like 'xeyes', or even 'xterm'.

if you do need openGL but don't mind it being (very) slow, search
about mesa3d. it's a software-only implementation of OpenGL but  i'm
not sure it works over a network.

if you _do_ need hardware accelerated 3d, search about vmgl; but i
don't know how complete is it already, or even if it's really usable.

another option is Virtualbox....

Hey Javier,

Thanks for replying! I tried installing x11-apps (for 'xeyer') and xterm but
get the same 'segmentation fault, dpkg: error processing x11-common
(--configure)' in both cases:

-------------------------
It is possible that my machine is lacking some basic files, even though I
have performed an update/upgrade.

Can someone provide pointers as to why I am unable to install any software
on my PVM?

As far as 3d OpenGL animation is concerned, I would prefer something like
'glxgears' but its not important. Thanks you for all your suggestions. Once
I am able to install software on my PVM, I will test with all of them and
see what works best.

Thanks again!

Use "xm info" in dom0 to find out the Xen version.  If it is indeed Xen 3.0, that is so ancient that recent kernels are bound to have some problems.

All,


I am working with Xen 3.0 (I think, though can someone please tell me how I could verify this!)

 

I want to install a couple of PVM which I could access with a X-terminal.

You are right. This thing is ancient. I do not have root privileges on this
machine and cannot change the xen-version. Do you think I could perhaps work
around this problem somehow! :-(

All I need to do for the time being is to get the GUI based application to
work via the network really.

Cheers

Re: Getting GUI to work with Xen PVMs

[Priya]

[-- Attachment #1.1: Type: text/plain, Size: 7639 bytes --]

All,

I have a 32 bit single processor dual core machines without hardware support
for virtualization on which I want to install the latest stable version of
Xen (4.0.0 ?), and then create a couple of para-virtual machines.

One of my requirements is to be able to access my PVMs remotely and run
graphics bases applications (glxgears, x11-perf, etc) on them. (An API
similar to XenCenter that works for Citrix
XenServer<http://community.citrix.com/display/xs/XenCenter>,
and in which you can access the console of all your VMs from a remote
machine would be even better).

I would like to get some recommendations about which is the good host
operating system, Xen version/settings and guest operating system to get
this to work. I found
this<http://bderzhavets.wordpress.com/2010/04/24/set-up-ubuntu-10-04-server-pv-domu-at-xen-4-0-dom0-pvops-2-6-32-10-kernel-dom0-on-top-of-ubuntu-10-04-server/>and
this<http://bderzhavets.wordpress.com/2010/06/02/setup-libvirt-0-8-0-xen-4-0-on-top-of-ubuntu-10-04-server-via-daniel-baumann-virtualization-ppa/>documentation
about installing Xen on Ubuntu 10.04 server and virt-install
(which I do not fully understand yet.)

One thought is to use Ubuntu 10.04 as my host OS, install Xen 4.0.0 and then
get  Ubuntu-xen-desktop<http://packages.ubuntu.com/hardy-backports/base/ubuntu-xen-desktop>
working
with a graphical interface as my PVM. Would this be the correct way to
proceed? Any thoughts or comments would be useful!

I guess most of my questions are rather naive. I apologize for that but I am
yet to see a Xen PVM with a GUI!

Thanks!
