Bug#606237: linux-kernel: poweroff-button fails on 2.6.32-5-openvz-686

Hi
I suspect that the problem is in the openvz patch for the kernel. My suspicion is that the poweroff button signal goes to vzeventd while it should not do that for VE0.
So the next step is to check the kernel code. I have forwarded your issue to upstream, but I have not seen any solution yet. 

But this is only a suspicion.

Hello Ola,

After starting vzeventd manually the

cat /sys/module/vzevent/parameters/reboot_event

has a value of 1 and the kernel module is loaded:

testa:~# lsmod | grep vz
vzevent                 1223  1
vzethdev                5593  0
vzrst                 108962  0
vzcpt                  93505  0
vzdquota               30157  0 [permanent]
vzmon                  12949  3 vzethdev,vzrst,vzcpt
vzdev                   1284  3 vzethdev,vzdquota,vzmon

I have developed a small formfactor
RAID/Samba/VPN/LVM-snapshot/Rdiff-backup/NX-server system for clients
and it runs nicely. But would be nice if clients could take down there
server with the poweroff-button if they go on vacation.

Any idea where to look further for a solution?

Many thanks for your help.

Richard

   Hello Ola,
   Both commands work like expected. Nothing special. Although the
   vzeventd is new for me.
vzeventd is new in latest kernel and latest vzctl. It is a new (improved) way 
for a VE to restart itself.


   Stopping OpenVZ: ..done
   Starting OpenVZ: ..done
   Checking vzevent kernel module .....done
   Starting vzeventd: Started

Ok. And what was the kernel modules after that?
You should have this module loaded "vzevent".
You should also have the value 1 in /sys/module/vzevent/parameters/reboot_event. 

But actually I do not think the power button should use vzevent but I just
want to check that things are working as expected anyway.


   Just to know sure, the powerbutton normally should work on almost any
   kernel? Is that correct?

Yes.

   Best regards,
