[Xen-users] How do you tell if a kernel will work with Xen?
In other words, what is the definition of "Wen aware"? I''m thinking of kernels that come packaged with Ubuntu. One way is to compile one yourself, reading the kernel compile docs, but the kernel needs to run on hardware with VT built in and my desktop machines don''t, and the server I rent is 64 bit dual core, so that''s a cross compile rather than one I could test here, then deploy. The deploying is not to dangerous though -- I''ll have a working kernel to fall back to booting with pygrub. Is cross compiling Xen aware linux kernels much different than a straight compile on the same machine you are running the kernel on?

In that case, mainline kernels newer than 2.6.23 should have the support, which does include ubuntu packaged kernels (you may want to try to stick to server, ec2, or -xen kernels as I think there were some reports of a specific version of Ubuntu''s desktop kernel lacking xen support, perhaps accidentally, 10.04 If I recall correctly)> One way is to compile one yourself, reading the kernel compile docs, > but the kernel needs to run on hardware with VT built in and my desktop > machines don''t, > and the server I rent is 64 bit dual core, > so that''s a cross compile rather than one I could test here, then deploy. > > The deploying is not to dangerous though -- I''ll have a working kernel to > fall back to > booting with pygrub.

I''ll let it be for a good while as I learn how to use Xen DomU''s On 06/16/2011 10:35 PM, Fajar A.

I''ll keep stability as top priority in my next choices. John _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
