Re: [Xen-devel] openafs not supported?

How are you compiling OpenAFS, and where?  OpenAFS expects to have a configured
linux source tree available, or at a minimum the kernel headers from a
configured kernel source tree.  It uses that to determine various things
during the compilation (like the sysname, architecture, etc...), and to
be able to compile the OpenAFS kernel module.  If the kernel headers are not
consistent (e.g. they claim to be for i386, but asm is linked to some other
architecture directory), things will fail badly.

Either way, I wouldn't call any of this problem a 'bug' given that OpenAFS
never claimed to support Xen (yet).  So, it's more a case of Xen simply not
being supported yet.  It is being worked on, though (at least from my side)
at a somewhat slower pace due to other work.  Any patches to add support for
Xen to OpenAFS would be welcome.  But either way, it will come to pass :)
