Thread-topic: Xen not detecting all my memory...
I've just noticed that Xen is only seeing 4G of memory, while the
machine actually has 6G.

The machine is a HP DL385 G2, and the memory configuration is:

1A - 1G
2A - 1G
3B - 2G
4B - 2G
5C, 6C, 7D, 8D - not installed.

'xm dmesg' says:

(XEN) Xen-e820 RAM map:
(XEN)  0000000000000000 - 000000000009f000 (usable)

(XEN)  0000000100000000 - 0000000120000000 (usable)
(XEN) System RAM: 4095MB (4193852kB)

Which looks like it is getting a proper e820 memory map and not a
fallback one...

Any suggestions?
