Enviroment setting
 
  1. Fedora12 + XEN 4.0 + 2.6.32.11-1.2.97.xendom0.fc12.x86_64
  2. Fedora12 + XEN 4.0 + kernel-2.6.32.12-1.2.103.xendom0.fc12.x86_64
 
We test these settings on Supermicro ,Quanta,DELL R210、R410、R710.
Only DELL R210,R410,R710 can reboot normaly.
Other machines will hang after we reboot from os.
 
We tried different settings of BIOS(EX: ACPI) and boot option (http://blogs.koolwal.net/2009/08/04/howto-fix-linux-hangfreeze-during-reboots-and-restarts/ ),and we still can't reboot normaly.
 
We also tried  OPEN SUSE 11.2 + XEN 3.4.1 + kernel 2..6.31(all from YaST2) on supermicro,and it can't reboot normaly, too.

Did you ret reboot=kbd on Xen's command line (not dom0's)?

Do you mean use "xm reboot=kbd" ?
 
 
By the way,we found the problem may be caused by xend.
in init 1 ,reboot is ok
in init 2 ,reboot is ok
in init 3 ,reboot hang
 
we manually start services which in init3 but not in init 2.
Reboot hangs if we start xend ini init 2.

RE: Reboot from OS will hang

[Sergey Kononenko]

Hi,

I've encountered the same problem. After reboot machine went to sleep
(or power off) mode, so I can't even reset it through IPMI, only
powercycle (by IPMI too) works.
I saw this problem only on new machine (Core i7 based, Xeon E5520,
Supermicro X8DTL motherboard), but on Pentium D and Supermicro
PDSMi reboot works.
Also server hangs after reboot only with pvops Dom0 kernels (I
tried stable-2.6.32.x and stable-2.6.33.x with hypervisors 3.4.3-rc and
4.0.0), but reboots normally with 2.6.30.4 "Xenified" kernel (under
3.4.3-rc and 4.0.0 too). All kernels and hypervisors were built for
x86-64 architecture.
Changing BIOS settings related to ACPI and reboot didn't help.
I tried all reboot= options in hypervisor command line: acpi, kbd,
triple, but it didn't help when pvops kernels were used.

With best reagrds,
Sergey Kononenko.
