Hi all ! I have a notebook with VIA C3 processor and would like to install Xen. It would have to work with this processor ? I knew that old versions of xen did not work with VIA processor. Thanks in advance roberto -- Ing.

And the main thing missing for Xen''s ability to run, is support for big pages (PSE IIRC). For CMOV you can workaround by compiling xen for a i586 cpu. Not sure if newers (?) C3 got that now, but the C7 does. Cheers, -- Vincent Hanquez _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
