Hello community, I''ve already installed Xen hypervisor over CentOS 6.0. I am wondering where can I obtain some patched guest OS kernels to get start. It seems that under PV mode, guest kernel needs to be modified (correct me if I am wrong). I am a newbie and have no previous experiences on Xen so any suggestions are appreciated. Thanks, -- Su _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org http://lists.xen.org/xen-users
A new-enough kernel m ( > 2.6.38 IIRC) *should* have support for Xen PV mode, because Xen front-end support has become part of the kernel; no need to patch. However, whether a distro''s kernel actually was compiled with Xen front-end support... now, that''s the question. If you have /proc/config.gz, try see how the kernel was compiled. If the kernel wasn''t compiled with Xen front-end support, you''ll have to acquire your distro''s kernel sources and configure+compile your own kernel.

Pandu, Thanks for the useful information. However, I couldn''t find config.gz in my kernel. Are there any other ways to check if the kernel include Xen frond-end drivers compiled?

Well, if the kernel your distro is using does not provide /proc/config.gz, try find-ing for "xen*" under /lib Post any files found here. Even if no files are found, there''s still the possibility that the Xen support is built into the kernel rather than implemented as modules. Anyways, I suggest directly asking the maintainers of your distro, if they compiled the kernel with Xen front-end support, and/or for the .config file they used when compiling the kernel.
