Hi, all

I have a server used to install Xen-2.0.6 on CentOS 4.1 i386, hardware
is DELL 2850, dual Xeon 3.2G CPU, 6G memory, use myself custom
compiled xen kernel(dom0 and domU), i know xen 2.0 on i386 only use 4G
memory, but i found on my server, it's only use 3327M memory, whit's
problem, who can help me?

Here is some info.

Your BIOS has created a whole at the top of the memory map into which the memory mapped PCI devices have been placed, effectively hiding the memory from use.

What is slightly odd is that the whole is larger than I've seen before. I presume its the area between cffff000 and e0000000 which isn't listed in the e820 map (everything above cffc0000 is unusable).

You'll have to wait until xen3 and use x86_32pae or x86_64 to use more memory.

I think it's maybe a bug, because if Xen 2.0 has 4G memory limit, even my Dell 2850 server has 6G memory , Xen 2.0 would use 4G memory on it, but it's just use 3327MB memory.

I have another server Dell 2650 with 4G memory dual Xeon 3.0G CPU, had install Redhat 9.0 and Xen 2.0, it's not have any problem, i has running 8 virtual server on it.

Here is my Dell2650 XenLinux system info.

I have the same problem on a pair of IBM eServer xSeries 346 (8840)
with 4Gb memory but Xen only sees 3199K

system : Linux
host : charlie
release : 2.6.10-xen0
version : #5 Wed Apr 27 17:45:51 IST 2005
machine : i686
cores : 2
hyperthreads_per_core : 2
cpu_mhz : 3200
memory : 3199
free_memory : 1

I can confirm the same "hole" as she11c0de on a Dell PowerEdge 1850
(ServerWorks chipset) -- only ~3.3G of RAM is seen by the machine out
of the 6GB of RAM installed.

And all of these are perfectly normal! Without PAE, the physical
memory space is limited to 4G. Then the chipset carves out a bit at
the top of that for PCI and AGP and whatever else, and yeah, they do
seem to take a bigger bite than is really necessary, but that does seem
to be normal.

Now that it's been explained, I'll be happy to accept any of that
surplus RAM for safe disposal. :-)

Now people have pondered this time and again (Who dies? Everyone dies)
We suspect that we're more than mere mortal remains (Oh, everyone dies)
Wise men and prophets they've all had their say
on the nature of our afterlives
But in case there's no beer there we'll have one more round (Oh everyone dies)

This is Xen specific. If I boot straight Debian I get all 4Gb.

It shouldn't be Xen-specific but it *is* non-PAE specific. i.e. Vanilla Linux
can support PAE to access all of your memory. Xen 2.0 doesn't support PAE so
it won't work. On Xen 3.0 you'll probably see all of it.

Cheers,
Mark
