I''m building xen source 4.1.2 on centos5.8. I did the steps according to this page http://wiki.xen.org/wiki/Xen_4.0_Release_Notes hg clone -r RELEASE-4.0.2 http://xenbits.xen.org/xen-4.0-testing.hg make xen make tools make stubdom make install-xen make install-tools make install-stubdom make kernels KERNELS="linux-2.6-xen0 linux-2.6-xenU" make linux-2.6-xen0-install But make kernels didn''t generate initrd. I called mkinitrd to generate initrd: mkinitrd -v -f /boot/initrd-2.6.18.8-xen0.img 2.6.18.8-xen0 Modulefile is /etc/modprobe.conf Looking for deps of module ehci-hcd No module ehci-hcd found for kernel 2.6.18.8-xen0, aborting. mkinitrd -v -f --builtin=ehci-hcd --builtin=ohci-hcd --builtin=uhci-hcd --builtin=mptsas --builtin=mptbase --builtin=ata_piix /boot/initrd-2.6.18.8-xen0.img 2.6.18.8-xen0 Then initrd-2.6.18.8-xen0.img file was generated in /boot, and i added it into grub.conf. But the system failed to boot xen! My kernel version is 2.6.18 I really do not know what''s wrong! Thanks a lot! _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org http://lists.xen.org/xen-users
