Solaris Nevada b106 is also affected in schema bellow.
Looks like hotplug scripts gets locked after VNC Session failure

OpenSolaris 2008.11 PV DomU may run VNC session started
via gnome terminal invoked on remote pvops Dom0 desktop pretty stable.
So , OpenSolaris PV DomU is not affected.
Actually , any remote VNC session with CentOS 5.2 PV DomU doing "yum upgrade" may be considered as network-intensive test and it works.
I don't think that network at DomU is broken in general.
But , path for vncviewer to CentOS 5.2 DomU via vncserver at Dom0 and vncserver at DomU seems to be broken in meantime.
This doesn't work for CentOS 5.2 DomU:-
WS - Work Station (Linux , Ubuntu Desktop)
WS --------------------->Vncserver Dom0 ------- xm create -c DomU.pyrun----
| |
| Vncviewer 1 Vncviewer 2
| | |
|----------------------------> Gnome Desktop Dom0 ----------->Vncserver DomU
This
works:-
WS -------------------->SSH conn to Dom0 ---- xm create -c DomU.pyrun-----
|
|
| Vncviewer |
|
|
|----------------------------> Gnome Desktop WS --------------->Vncserver DomU

2.
This configuration provides remote connection to Dom0 with pvops
kernel via Gnome Desktop. Crash happens when i run VNC session opened via gnome
terminal at remote Dom0's desktop ( it worked fine with rc5 or rc6 for
sure).

That's a bit worrying, because it would suggest that networking in general
is broken. If you don't start Xvnc (or whatever), but run some other
network-intensive test, does that crash?
