Xen users - Feb 2009 - Xen 3.3.1 pv-linux vm reboot -> State hangs on: ---s--

Hi,

we are currently trying to upgrade our debian based infrastructure to  
debian lenny, but I''m running into a problem on rebooting from within  
a paravirtualized linux vm.
after I type "reboot" within the vm, the vm shuts down properly, but  
then never boots up again:

xm list
Name                                        ID   Mem VCPUs       
State   Time(s)
Domain-0                                     0   725     1      
r-----     46.2
g-m5t12oln                                   1   256     8     --- 
s--      3.0

the setup looks like this:

	debian lenny
	kernel: lenny 2.6.26-1-xen-amd74
	xen: 3.3.1 compiled from source


any idea what the problem could be or how I could debug it, to nail  
down the cause?

Lg Philipp

What does /var/log/xen/xend.log say?
Do you have any "on_reboot" line on your domU config file?

Hi,

those are our on_* settings:

on_poweroff = ''destroy''
on_reboot = ''restart''
on_crash = ''restart''

the same config file works as expected on a debian etch host with xen  
3.3.1.

But I have I''ve got a bit farther to the problem now:

	If I reboot a domU from within the domU it hangs on state s after  
shutdown
	It will hang there forever until I create another domain. If I create  
another domain, the one hanging at state s also gets started again.
	It won''t work with destroying another domain.


I have attached the xend.log output from the following scenario:

	create domU: g-m5t12oln
	reboot domU g-m5t12oln from within vm
	(g-m5t12oln hangs on state s now)
	
	create domU: g-nbjaohbe
	(g-m5t12oln starts too now)

	reboot domU g-nbjaohbe from within vm
	(g-nbjaohbe hangs on state s now)

	destroy g-m5t12oln
	(g-nbjaohbe still hangs on state s)

	create domU: g-m5t12oln
	(g-nbjaohbe starts too now)
