CentOS 4.5: Advice on upgrading memory beyond 4GB with VMWare involved
I have a server running CentOS 4.5, it is fully updated to the latest software using yum. I am considering upgrading the memory to 8GB. I have done some research and concluded that I need to install the kernel-hugemem package via yum and reboot. The server is running a few production VMWare server images; therefore, I need to keep downtime to a minimum.
I am aware VMWare ships with a kernel module, which is built against the kernel source; hence, will I need to install the kernel source for the kernel-hugemem package and has anyone done anything similar, and if so, what other pitfalls I am likely to hit?
