Hey gang,
I have been trying my hardest to get KVM running on a 32-bit CentOS 5. I know
"upstream doesn't support it", but from what I gather, it *is*
possible.
I've tried downloading the KVM source, but get nailed on compile with:
LINK i386-softmmu/qemu
make -C /lib/modules/2.6.18-308.1.1.el5PAE/build M=`pwd` \
LINUXINCLUDE="-I`pwd`/include -Iinclude \
-Iarch/x86/include -I`pwd`/include-compat \
-include include/linux/autoconf.h \
-include `pwd`/x86/external-module-compat.h " \
"$@"
LD /usr/local/kvm-88/kvm/kernel/x86/built-in.o

Has anyone built RPM packages for this? Ideas on how to compile? I'm
running
the kernel: 2.6.18-308.1.1.el5PAE
Thanks.

Ideas on how to compile? I'm running > the kernel: 2.6.18-308.1.1.el5PAEThere is no way you are going to build anything that new (kvm-88) for the 2.6.18 kernel The real problem is that RH has backported a bunch of items into the 2.6.18 kernel, otherwise you would not be able to attempt this at all. KVM recommends at least a 2.6.20 kernel to use a very old version of KVM (kvm-17): http://www.linux-kvm.org/page/Choose_the_right_kvm_%26_kernel_version I would look at this version: http://vault.centos.org/5.6/centosplus/SRPMS/kvm-kmod-36-3.src.rpm (which did work on i686) I would see if I could look at what patches, etc, are in that SRPM and I would see if I could do anything similar with newer versions of KVM. BUT ... the bottom line is that if it was stable, Red Hat would release it for RHEL. Since they do not do so, it is likely not stable and making it stable will likely be very difficult. If if was not difficult, then Red Hat would do it for RHEL :D -------------- next part -------------- A non-text attachment was scrubbed...

They are perfectly fit latest kernel 2.6.18-308.1.1.el5 (not PAE). I've installed them without issues. KVM module loads in the kernel. I have not tried anything yet. But suppose it'll work. http://rpms.plnet.rs/plnet-centos5-i386/RPMS.plnet/ http://rpms.plnet.rs/plnet-centos5-i386/RPMS.plnet-releases/plnet-ser-release-1.0-0.el5.noarch.rpm
