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?

If the system is fully updated via yum then are you should be running CentOS 4.6. When was the last time you checked and/or ran: yum check-update

Nope you do not need the kernel source, you do need to have the kernel-hugemen-devel rpm package that matches the running kernel.

You are quite right in thinking I should be on CentOS 4.6: Luckily for me I am, apologies for dodgy info. I installed using the 4.5 CD so I'm still mentally stuck on that version :-)

Thanks for the info, I'll crack on and try it once my new memory arrives.
