I've trying Xen 4.0 on Ubuntu 9.10. (xen-test-ubuntu
2.6.32.11-xen0-amd64 #8 SMP x86_64), but i have some problem
with xm pause command. It hangs.
                
After about 120 seconds I have the follow syslog message:
                
        [58921.334917] INFO: task xend:27739 blocked for more than 120
        seconds.
        [58921.334923] "echo 0
        > /proc/sys/kernel/hung_task_timeout_secs"
        disables this message.

Then, after a "xm destroy" command, xen doesn't work more. If I
do "xm create windowsXP.cfg" again I received the follow message:
              
Using config file "./windowsXP.cfg".
Error: Device 768 (tap2) could not be connected. Hotplug scripts not
working.
                
No substancial messages at xend.log or xend-debug.log.
                
                
The same windows machine is working on a 2.6.31.8-xen0-amd64 #1
SMP Tue
Apr 6 17:04:48 BRT 2010 x86_64 with Xen 3.4.2.
                
Someone can help me?
                
Att,
