CentOS 5.1 Released
Sunday Dec. 2, 2007 CentOS-5.1 was released, this was long awaited after the November 7, 2007 Release of Red Hat Enterprise Linux 5.1. So what’s the big deal? Intergrated Virtualization with Xen Hypervisor v3.1, updated LVM, GFS, Clustering Tools, ISCSI Utils and numerous other packages. The upgrade from CentOS-5 to CentOS-5.1 is performed witha simple ” yum update -y“, then sit back and enjoy a dark cup of joe. Depending on your connection speed and system speed this could take some time.

The update completed without incident, after a reboot to load the new kernel “2.6.18-53.1.4.el5” everything looked good. The final step was to recompile some of the vendor specific drivers for the Fibre Channel HBA’s. Each server has 2 HBA’s for Failover and load balancing connected to redundant Fibre Switches on the MSA1000.
For the past couple months I have been testing PV (Para Virtualized) Guest Hosts running under Xen on CentOS-5 x86_64. The servers and storage device (MSA1000) are very robust, Dual Core, Dual Opterons with 14GB ram attached to a storage device via Fibre Channel. Live migrations of guest systems are a breeze, they take less than one minute to fully migrate from one physical server to another.
