help! CentOS 5.1 + Xen kernel doesn’t see all the RAM in my PC
I’ve run into quite a few odd issues with CentOS 5.1 x64 & the Xen kernel. One of them being the fact that it only sees about 480MB RAM, even though my server has 2GB RAM. So, searching the net, I came across this post: https://bugzilla.redhat.com/show_bug.cgi?id=250299 which states that grub-0.97-13 has a problem with mapping all the memory with a Xen kernel. The fix? Simple, upgrade to grub-0.97-14, with the following commands: [shell] rpm -Uvh ftp://ftp.zouric.com/public/grub-0.97-14.x86_64.rpm [shell] This will install grum 0.97.14. Once done, you need to reinstall grub to the HDD as well, like so: [php] grub-install /dev/sda [/php] PLEASE NOTE: This statement assumes you boot from /dev/sda by default. If you have IDE HDD’s, you need to use /dev/hda
