Hi all, I would like to know the right way to install xen3 from source. This is my current installation procedure. First: vi Makefile #KERNELS ?= linux-2.6-xen0 linux-2.6-xenU KERNELS ?= linux-2.6 This step isn''t necessary now, right? and then I do: 1. make linux-2.6-xen-config CONFIGMODE=menuconfig 2. make dist 3. make install 4. make linux-2.6-xen-build 5. make linux-2.6-xen-install If I want to recompile the kernel to include or exclude modules, I do steps 1, 4, 5. This works, but is there a better/faster way? Thanks. Chris. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

And if you split into xen0 and xenU kernel, you can cut each single kernel even more, and you are faster if you ony need to change one of these. There was a question here once asking which kernel features must keep in the kernel to keep xen fully working, but was never answered.

Hi.
This is not xen-only stuff, but I use ccache to speed up compilations.
Install it and add these lines to your .bash_profile.
if [ -d /usr/lib/ccache ] ; then
PATH=/usr/lib/ccache:"${PATH}"
fi
The package files location might vary depending on your distro. It saves a
lot of time when recompiling.
