which hypervisor are you running on? XEN ? or KVM ? for KVM user, you sholud do: *su -c 'yum install kernel-devel'* *dmesg | grep kvm* to make sure you're running KVM environment
for XEN user, you should do: *su -c 'yum install kernel-xen-devel'* *xm info* to make sure you're running XEN environment I'm so sorry but I have the same problem > > knowing that I build Openvswitch with this command line > ./boot.sh > > what is your Open vSwitch version, or you pull it from git tree ? > ./configure --with-l26=/lib/modules/2.6.18-238.19.1.el5/build/ > > if you pull the version from the git tree, you should run with the command --with-linux, but not --with-l26 I suggest you to use /lib/modules/`uname -r`/build, for making sure that it is compatible to you Linux kernel > make > sudo make install > > and when I load Openvswitch module I have this error > > insmod: error inserting 'datapath/linux-2.6/openvswitch_mod.ko': -1 Invalid > module format > > see above > dmesg | tail > > if you're running KVM * dmesg | grep kvm * you will see two line output kvm kvm_intel OR kvm_amd openvswitch_mod: version magic '2.6.18-238.19.1.el5 SMP mod_unload gcc-4.3' > should be '2.6.18-164.15.1.el5 SMP mod_unload gcc-4.1' > > I think the problem is related to the version of the kernel > because when I execute uname -r I have this result > "2.6.18-164.15.1.el5" > and when I build openvswitch I use this version "2.6.18-238.19.1.el5" > because in /lib/modules/2.6.18-164.15.1.el5 we haven't build directory > > Thank you in advance > Best regards > Marwen > >
