Hi Shiriam, I''ve noticed there''s a fair amount of mention of the need for "suspend event channel" support in the domU kernel when using Remus, and there''s some mention of certain kernels that support it (e.g. http://xenbits.xen.org/hg/linux-2.6.18-xen.hg/) However, I''m running Ubuntu 12.04+ these days, and I don''t think I''d want to install that kernel in favor of the linux 3.5 kernel it comes with (?). I was trying to see if there''s a way to be able to compile a custom kernel with the required support? I just couldn''t figure out exactly what having "suspend event channel support" means (e.g. is it a driver, a config option, a code change), and was hoping you might be able to help? Thanks!

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 shriram On Mon, Feb 18, 2013 at 4:31 PM, Andrew Eross <eross@locatrix.com> wrote:> And sorry I messed up your name, Shriram =) > > On Mon, Feb 18, 2013 at 6:31 PM, Andrew Eross <eross@locatrix.com> wrote: >> >> Hi Shiriam, >> >> I''ve noticed there''s a fair amount of mention of the need for "suspend >> event channel" support in the domU kernel when using Remus, and there''s some >> mention of certain kernels that support it (e.g. >> http://xenbits.xen.org/hg/linux-2.6.18-xen.hg/) >> >> However, I''m running Ubuntu 12.04+ these days, and I don''t think I''d want >> to install that kernel in favor of the linux 3.5 kernel it comes with (?). >> >> I was trying to see if there''s a way to be able to compile a custom kernel >> with the required support? >> >> I just couldn''t figure out exactly what having "suspend event channel >> support" means (e.g. is it a driver, a config option, a code change), and >> was hoping you might be able to help? >> >> Thanks! >> Andrew > >
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.
