A Docker container is for a single application.  Doing more than that usually 
means you have to use supervisord or something like that.  Now OpenVZ can run a 
complete distro with lots of processes... but in any event... for containers 
I'd recommend you check out x2go.  x2go is awesome.

I can not duplicate this on a RHEL/clone host running Fedora VMs.  Just out of 
curiosity, why would you want to run virt-manager inside of a VM?  You aren't 
doing nested KVM are you?

Just to clarify... you are running the KVM VM on the same machine or a 
different one and connecting to it via a SPICE client?  You mentioned ssh so I 
wasn't sure.

Be my guest.  I'm not a programmer.

I can tell you that I'm not aware of anyone doing accelerated 3D stuff in a 
remoting protocol.  Perhaps PC-over-IP (VMware View) does?!?

3D is listed as a future feature. :)

I've used Fedora 16, 17, and 18 and they preform well.  Here's the answers to 
the best of my knowledge.

Xubuntu 12.04.1 - xserver-xorg-video-qxl 0.0.16-2

So far as the invocations go... whatever virt-manager produced.  I used the

So far as the xorg.conf goes... I didn't do anything special.  They 
auto-configured and so far as I know use a dynamic config rather than an actual 
file.  xorg has been that way for some time now.  I know you can make an 
xorg.conf and tell it to use that but it seems to do a fairly good job and if 
it ain't broke, I don't try to fix it.  Well, in this case, maybe it is broke. 
:)

The KVM host both of those are on is:

Red Hat Enterprise Linux Server release 6.3 (Santiago)
kernel-2.6.32-279.19.1.el6.x86_64
qemu-kvm-0.12.1.2-2.295.el6_3.10.x86_64
libvirt-0.9.10-21.el6_3.7.x86_64

So far as anything else goes... it is fully updated so whatever the current 
versions are in RHEL6.

Javaon,

> already disabled, still slow response in GUI. :-(

It didn't even work until recently (with the release of Fedora 17) as seen in 
this features page for Fedora 17:

https://fedoraproject.org/wiki/Features/Gnome_shell_software_rendering

As you probably know, GNOME 3 has the 3D required desktop and the Fallback mode 
desktop.  I believe the Fallback mode is supposed to be discontinued if it 
hasn't been already... but if it is there, you can use that and it should be 
much faster.

Other than that... NO there isn't anything you can do to fix it.  You'd have 
the same problem pretty much with any composited desktop that wants hardware 
accelerated 3D.  As someone already said, Windows works ok because it disables 
the Aero interface.

KDE's 3D stuff seems to work fairly well in SPICE but KDE has two modes and 
doesn't require hardware accelerated 3D for one of them... which is the one 
that works.

So, if putting a fork in your eye hurts, don't put a fork in your eye.

You could run your GNOME 3 desktop on a really fast VM host and have a really 
fast client connect to it... with a really fast connection (1Gbit) and it'd 
probably work a little better... but until SPICE ads support for hardware 3D 
acceleration... or the GNOME 3 guys change it, you get what you get.  In fact, 
there are a bunch physical machines withof video cards that don't work well on 
Linux that GNOME 3 either won't run on at all... or runs poorly.

[Spice-devel] Question about poor performance of Ubuntu VMs

2013-01-24 Thread Scott Dowdle
Greetings,

I'm a big Red Hat / clone slash Fedora guy... and I use use a lot of KVM.  I 
primarily create Fedora, RHEL/clone, and Windows KVM guests and they work 
great... but every once in a while I like to try out an Ubuntu release just to 
see what's new.  I have tried their Unity spin as well as their Xubuntu spin... 
for a few releases now.  I'd expect Unity to be slow because it is similar to 
GNOME 3 in that it wants to do that 3D stuff.  But with Xubuntu and XFCE, I'd 
expect it to be snappy.  That has NOT been my experience.  It is really slow.  
Moving a window around is extremely choppy and it can even lag out (where it 
doesn't respond at all) for periods of time.  I haven't done much 
troubleshooting of this but I have done a few installs on a variety of hardware 
(for the host node) and used a variety of client machines and the pokey 
experience has been the same.

I suspect it has something to do with the mouse emulation used because the 
Xubuntu desktop seems to perform fairly well until the mouse is moved.

Any ideas?  Maybe there is some configuration change either in KVM or in 
Xubuntu that will improve the situation.  I use virt-manager to create the 
guests (on Fedora and RHEL) and pick the closest Ubuntu version listed.

>  required? I really hope someone can point me in the right direction.

I haven't looked to verify but the last time I looked the situation hadn't 
changed... and someone already pointed this out... but whoever maintains it 
didn't fix it.  They removed the library package from the website by accident 
thinking it was old or no longer needed... so so anyone who wants to install 
the Windows client can't.  Thanks free software! :)

Yeah, the packaging for the MS Windows version was horrible but I think that 
was because they want to cross compile it from Linux and use no proprietary 
bits in the process... so no fancy installer.

I think they are working on replacing the previous MS Windows client that is 
based on Crazy Larry's Toolkit (or something like that) and replacing it with a 
full-blown version of virt-manager for Windows along with virt-viewer and 
remote-viewer... which last time I checked where command line oriented clients.

It would be nice to hear what the plans are... AND to get the current situation 
fixed... but it is easy to complain from the audience. :)

A specific GIMP issue and any X activity ARE NOT the same bug so NO you DID NOT 
report it many months ago.

I noticed the GIMP issue (but didn't report it) about a year ago.  I haven't 
had the first bit of problems with general X stuff causing performance 
issues... but then again I haven't been using SPICE much lately.  My guess 
would be that it might be video card specific on the client side... but I 
really have no idea.

I just tested virt-manager on one of my RHEL 6.1 boxes and it includes QXL and 
SPICE but the system does not have the spice-gtk package installed... since 
there isn't one.  Some other package is providing the functionality.

The only spice related packages that I see installed on the system are:

spice-vdagent-0.6.3-8.el6.x86_64
spice-server-0.8.0-1.el6.x86_64

The description of spice-xpi on that page says:

"Spice-XPI plugin for mozilla plugin compatible browsers. This is used for 
launching the spice client from the RHEV-M user portal."

I would assume that the URL one clicks on in the RHEV-M user portal contains 
the same basic info that spicec would use to connect to a remote KVM VM via 
SPICE... host, port, password, and cert?  If so, is there some documentation 
somewhere that specifies how one constructs the URL?  I don't currently have 
access to RHEV for Desktops to see what the URLs look like.

I know the source code to spice-xpi is the ultimate documentation... and I 
looked at the contents of the .tar.gz file... for the various documentation 
that might be included with the source.  I didn't find much info... and I'm not 
programmer-ish enough to look directly at the source to piece the info together.

> I wanted to use virt-manager which is packaged with ubuntu, but I

So far as I know, SPICE support in libvirt and virt-manager has only been in 
for a few weeks... and Fedora only offers it in their virt-preview repo that 
allows Fedora 14 users to pull packages from the upcoming Fedora 15.  My point 
is that Fedora is usually much more bleeding edge than Ubuntu so I'd be 
surprised if Ubuntu offered libvirt and virt-manager with SPICE support 
already... unless they are really on the ball... or have a preview repo you are 
using?  I'm just guessing though.

Non-virt-preview repo users of Fedora won't get the updated packages until 
Fedora 15 is released which is supposed to be the middle of May... or someone 
decides to give the beta or later test releases a try.

To the best of my knowledge, SPICE is tied to KVM/QEMU because it is designed 
to use a virtual video device that is provided by a modified KVM/QEMU.
