Hello,

Last night I upgraded a server to CentOS 5.2.  The server has 16GB of
RAM.  Now that it's running 2.6.18-92.1.6.el5xen only 8GB is
reported to
exist.

How much memory is available?  Is this a known issue?

I think there was a topic like this about a month ago, please search the list archieves.

Cheers.

In case he didn't find it, I was the one that posted the original issue. Turns out that Xen allocates memory to domU's and doesn't release it back to dom0 even if you stop the VM's. Top only reports the memory available to dom0. The xen tools will show the proper amount of memory.
