This function is only in the svm (AMD) code and should not appear on an Intel system. I see that this function is not being clled at all when I am running my apps as I have put printk in the functions and they do

Hi all don''t get such envionment to try now. so ask for help here. imagine that two os installed. Xen3.1 + Linux is installed in /dev/hda and windows xp is installed in /dev/hdb I don''t want to reboot to use windows. Is it possiable to boot the hdb windows in xen? i saw there are some threads about P2V in this mail list. will the P2V tools help? thanks
