Xen users - Jan 2006 - When I start the application on VM, the Host one is getting activated

This is a bit strange,
I ssh (with X forwarding) into dom0 from a domU.  Then I start the
mozilla browser on the ssh'ed machine. The browser window opens up.
when I save some web page, the page gets saved on the Host machine.
so it means if an application 'X' resides in both domU and dom0, and
when we are connecting to domU from dom0 through a ssh session, and
starting the application 'X' on domU, the application on dom0 is
actually what is running ?

Any suggestions why this is so ?

regards
Sanjay Upadhyay

Do you already have a Mozilla session running that was started from the 
host? If so, there''s a very good chance that what''s actually
happening
is that the preexisting host browser session is starting a new window 
rather than starting a new, remote browser session. Mozilla has 
functionality for controlling existing instances via X11 for this purpose.

HI Charles,
tryi to SSH into a Physical Machine (no xen), I start the browser, and
the browser is running on the remote physical machine, when I save
something it gets saved into the remote machine..
However on Xen... when specifically the dom0 and domU are on the same
physical machine and I SSH into somU, I see this effect.

regards

Whether the mozilla-xremote-client is attempted before the actual remote 
browser is started likely depends on the startup scripts bundled in the 
browser package for your distribution. Is your remote physical machine 
running the same OS and Mozilla version as your DomU?

In short -- there are other factors besides Xen which impact whether 
this will work. Closing all browser instances on the Dom0 would be an 
effective way to stop it from happening, though.

Hi charles,
strangely..
I find it hard to believe..
my dom0 is in debian woody
my domU is Susle Sles 9
and closing all instances of mozilla and firefox, doesnt prevent the
mozilla instance of the host to be invoked..
however when ssh'ing into a debian machine which is not a xen domU,
but a physical Debian machine connected through lan, and invoking a
mozilla instance brings up the remote mozilla.

I am using the hg version of xen..

thanks for your help although..

regards
