[vbox-dev] Compiling virtualbox kernel module on xen architecture

[alessandro cunsolo]

Hi,
I'have tried to compile virtualbox kernel module on xen architecture, but
the building of the module have generated a compilation error.
With linux kernel 2.6.26-1-686, the building of module don't generate
errors, with linux-kernel-2.6.26-1-xen generate this errors:

/usr/src/modules/virtualbox-ose/linux/SUPDrv-linux.c: In function
‘VBoxDrvLinuxInit’:

make[1]: Leaving directory `/usr/src/linux-headers-2.6.26-1-xen-686'
make: *** [vboxdrv] Error 2

I have added:

#undef CONFIG_X86_LOCAL_APIC

in SUPDrv-linux.c and the building of module have success, but when I start
a virtual machine virtualbox stops in "spawing session".

Any idea what I can do ?

Thanks.
