Hello,
Earlier this week I installed a test server with CentOS 5.6 with Virtualization enabled during the installer. Today I installed another server using the same method (they are identical servers). I just did a yum update and I found something curious. Both servers have a different kernel. Server 1 is at 9.1 version and server 2 at 5.1. How can this be? How to I get the latest version on server 2? If I run yum update there are none available.
If I input xm info I get this one server 1:
host : server1 release : 2.6.18-238.9.1.el5xen version : #1 SMP Tue Apr 12 18:53:56 EDT 2011 machine : x86_64 nr_cpus : 4 nr_nodes : 1 sockets_per_node : 1 cores_per_socket : 4 threads_per_core : 1 cpu_mhz : 2400 hw_caps : bfebfbff:20100800:00000000:00000940:0000e3bd:00000000:00000001 total_memory : 4095 free_memory : 383 node_to_cpu : node0:0-3 xen_major : 3 xen_minor : 1 xen_extra : .2-238.9.1.el5 xen_caps : xen-3.0-x86_64 xen-3.0-x86_32p hvm-3.0-x86_32 hvm-3.0-x86_32p hvm-3.0-x86_64 xen_pagesize : 4096 platform_params : virt_start=0xffff800000000000 xen_changeset : unavailable cc_compiler : gcc version 4.1.2 20080704 (Red Hat 4.1.2-50) cc_compile_by : mockbuild cc_compile_domain : centos.org cc_compile_date : Tue Apr 12 18:01:03 EDT 2011 xend_config_format : 2
And on server 2 it is this:
