Hi,Krysan

I have no problem to boot 32 bit SLES10 SP1 RC2 HVM guest with 4 vpus on 64bit 
host against latest xen unstable.

My test box is a bensley with 16GB mem. I specified 512M for the HVM guest.


Thanks
Yunfeng

Hi Yunfeng.

I am having problems with 32-bit SLES10 2.6 VMX on 64-bit SLES10 xen as 
outlined below.

I see from your vmx status reports that you are able to:
  Bootup unmodified FC5 IA32 nonPAE SMP 2.6 Linux VMX domain
  Bootup unmodified FC5 PAE SMP 2.6 Linux VMX domain.

How many processors and how much memory do these two domains have?
Have you ever seen problems similar to mine? 

Thanks,

I cannot boot 32-bit SLES10 HVMs since changeset 14201.

32-bit SLES10 hvm (4x 2gb) hangs in blue SUSE Linux screen
32-bit SLES10 PAE  (4x 16gb) kernel panics as follows:
     Kernel panic - not syncing: Fatal exception in interrupt
     Badness in smp_call_function at arch/i386/kernel/smp.c:595

Neither serial port nor logs give any indication what is happening.

I saw changes in changeset 14392 to 32bit bios support module, so rebuilt with 
changeset 14391and retried the 32-bit SLES10 non-PAE and it boots fine.

Has anyone else had problems booting 32-bit SLES10 hvms on 64-bit hypervisor?
