I''m attempting to build a 32bit DomU on a 64bit server. i run `make menuconfig` and then attempt to load `./buildconfigs/linux-defconfig_xenU_x86_32`. When doing this i see a bunch of errors and then the config screen pops back up with all the xen stuff missing. If i load the linux-defconfig_xenU_x86_64 config instead i dont see the errors and the xen options are still there. Am i doing somthing wrong here?

Add "ARCH=i386" to all your make command lines, e.g. # cp buildconfigs/linux-defconfig_xenU_x86_32 .config # make ARCH=i386 oldconfig Ian. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
