Re: [Xen-users] Remus Suspend event channel kernel support

[Andrew Eross <eross@xxxxxxxxxxxx>]

Ahh gotcha, ok, thanks Shriram, it was tricky to discern that until now.

For my lab experiment here I think I'll just use a OpenSuse domU then for now as it sounds like the easiest path.

Many thanks,

Andrew

Hi
 The suspend event channel support exists in all Open SuSE kernels
afaict. 3.* kernels inclusive.
  It hasnt made its way into mainline.
  It is not a config option. It requires some code modification and
cannot be selectively enabled, in a clean way.
  I tried to add the event channel support to the kernel during the
3.0 release cycle. I couldnt quite get it to work and decided to drop
it.

  2.6.18 domU these days is certainly not a good choice :P.
  But you might be able to pull a Suse kernel, compile and change it
to a .deb package, to install on the Ubuntu domU.

cheers
