[kvm-devel] current kvm userspace git doesn't compile on i386

[Christoph H. <hc...@in...>]

Current kvm userspace git configured with ./configure --prefix=/opt/kvm --with-patched-kernel --qemu-cc=/usr/bin/gcc-3.4 gives:

Try to build the kernel modules too (remove '--with-patched-kernel' from 
./configure arguments ):
./configure --prefix=/opt/kvm --qemu-cc=/usr/bin/gcc-3.4 ; make -C 
kernel LINUX=<path-to-linux-git-tree> sync; make
You will have to rmmod current kvm modules and insmod the built modules 
under <KVMDIR>/kernel.

A ./configure --prefix=/opt/kvm --kerneldir=/home/hch/work/linux-2.6-xfs
gives the same error as in my first post.  Your suggestion
(./configure --prefix=/opt/kvm --qemu-cc=/usr/bin/gcc-3.4;
 make -C kernel/ LINUX=/home/hch/work/linux-2.6-xfs) gives the
 following:

make[4]: *** No rule to make target `/home/hch/work/kvm-userspace/kernel/svm.o', needed by `/home/hch/work/kvm-userspace/kernel/kvm.o'.  Stop.

This doesn't work with rsync complaining.  But I don't really want new
kernel code anyway, and I would be very surprised if building a
different kernel would fix a userspace link error given the obvious
boundary between kernel and userspace code.

I'm not suggesting to build the whole kernel, just the kvm-modules 
(instead of using the kvm-modules that came with linux).
It seems that your current kvm modules know nothing about vapic, while 
your kvm-userspace assumes they do.
