Hi list,
I have an IBM xseries 345, running CentOS 5.3, hosting a few Xen domUs.
However, I need more RAM -- but cannot remember if all (four) RAM sockets are populated (which would mean to buy higher capacity modules) or if there are two slots left to use.
However, I'd like (and think that it's possible, but don't remember how) to check remotely.
dmesg's first lines:
