Because sipXecs 4.0.0 installer ISO is missing /etc/redhat-release, yum updates are not possible. To correct the problem, run ‘rpm -ivh http://mirrors.kernel.org/centos/5.2/os/i386/CentOS/centos-release-5-2.el5.centos.i386.rpm’. After this completes, you should be able to use the yum repositories to update and install software. In particular, this is useful for replacing the kernel with a kernel-vm or kernel-xen build for virtualiztion.
