[Xen-devel] problems compiling Xen 3.1.3 after making changes to the config
Hello, I am trying to compile and boot Xen 3.1.3 with linux-2.6.18.8-xen on a FC5 machine (gcc 4.1.0). I modified the default linux-2.6.18.8-xen/.config file by doing the following 1) cd xen-3.1.3/linux-2.6.18.8-xen/ 2) make menuconfig (marked ide drivers to be compiled in instead of as modules) 3) cd ../ 4) make Make fails with the following message ------------------------------------------------------------------------------------------------------- make[3]: Entering directory `/root/xen-3.1.3/build-linux-2.6.18.8-xen_x86_32'' make -C /root/xen-3.1.3/linux-2.6.18.8-xen O=/root/xen-3.1.3/build-linux-2.6.18.8-xen_x86_32 vmlinuz Using /root/xen-3.1.3/linux-2.6.18.8-xen as source for kernel /root/xen-3.1.3/linux-2.6.18.8-xen is not clean, please run ''make mrproper'' in the ''/root/xen-3.1.3/linux-2.6.18.8-xen'' directory. make[5]: *** [prepare3] Error 1 make[4]: *** [vmlinuz] Error 2 make[3]: *** [vmlinuz] Error 2 make[3]: Leaving directory `/root/xen-3.1.3/build-linux-2.6.18.8-xen_x86_32'' make[2]: *** [build] Error 2 make[2]: Leaving directory `/root/xen-3.1.3'' make[1]: *** [linux-2.6-xen-install] Error 2 make[1]: Leaving directory `/root/xen-3.1.3'' make: *** [install-kernels] Error 1 ------------------------------------------------------------------------------------------------------- Any help is appreciated.

You will need to run "make mrproper" in xen-3.1.3/linux-2.6.18.8-xen to undo what you did already. The issues is that the Xen build system uses out of tree builds (the Oin the output below) so source is in linux-2.6.18.8-xen and objects are in build-* (this saves having multiple copies of the source). You have caused the source tree to be used as an object tree which leads to the error you have observed.> 2) make menuconfig (marked ide drivers to be compiled in instead of as > modules) > 3) cd ../ > 4) make > > Make fails with the following message > ------------------------------------------------------------------------------------------------------- > > > > make[3]: Entering directory > `/root/xen-3.1.3/build-linux-2.6.18.8-xen_x86_32'' > make -C /root/xen-3.1.3/linux-2.6.18.8-xen > O=/root/xen-3.1.3/build-linux-2.6.18.8-xen_x86_32 vmlinuz > Using /root/xen-3.1.3/linux-2.6.18.8-xen as source for kernel > /root/xen-3.1.3/linux-2.6.18.8-xen is not clean, please run ''make > mrproper'' > in the ''/root/xen-3.1.3/linux-2.6.18.8-xen'' directory. > make[5]: *** [prepare3] Error 1 > make[4]: *** [vmlinuz] Error 2 > make[3]: *** [vmlinuz] Error 2 > make[3]: Leaving directory > `/root/xen-3.1.3/build-linux-2.6.18.8-xen_x86_32'' > make[2]: *** [build] Error 2 > make[2]: Leaving directory `/root/xen-3.1.3'' > make[1]: *** [linux-2.6-xen-install] Error 2 > make[1]: Leaving directory `/root/xen-3.1.3'' > make: *** [install-kernels] Error 1 > > ------------------------------------------------------------------------------------------------------- > > > Any help is appreciated. > > > Thanks, > Girish > > _______________________________________________ > Xen-devel mailing list > Xen-devel@lists.xensource.com > http://lists.xensource.com/xen-devel_______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Re: [Xen-devel] problems compiling Xen 3.1.3 after making changes to the config
Thanks Ian. I tried what you suggested and Xen compiled fine.
Now another problem has cropped up. When I try to boot up dom0, I get a
kernel panic. I am compiling Xen 3.1.3 on FC5. I have made sure that all IDE
modules (my disk is IDE) are compiled in and are not modules using the make
menuconfig.
I am building the ramdisk using mkinitrd initrd.img 2.6.18.8-xen
My grub.conf is
------------------------------------------------
# grub.conf generated by anaconda

# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You do not have a /boot partition. This means that
# all kernel and initrd paths are relative to /, eg.

I have shown the panic message below. (Full boot up message in file

I tried searching for this "unable to handle kernel paging" error on
the
mailing list, but I could not find any fix for it.
Any ideas why the kernel panic happens?
Thanks,
