I don't like to have that 'maxmemory' restriction. If hotplug is enabled, I
want
to be able to
add unlimited amount of memory?
Yes. (I don't have check qemu code limit, but maxmemory=2TB is working)
Not sure if we really need 2TB with hotplug? I mean, if someone really starts
a VM with
(With my last patch, I fix the static memory to 512MB(or 1GB) if you want,
so all upper memory is dimm devices.
Note that 4TB is the physical limit for 64bits system. (and for qemu)
A real 64bit system is not limited to 4TB, because 2^64 is 18446744073709551616.

But I guess current processors do not use 64 address lines ;-)
Current processors use 48 bits for addresses, so 2^48 -1 =

I am also thinking about changing the 'hotplug' config like this:

so that we can selectively enable them.

Like this we only need 1 memory option (min:512), which seem easier for user.
What do you think about it ?
Also, from my point of view we can require a limit of 1GB mem. I guess this
would be
safer to boot.

Hi,
I have done some tests,
and it's seem that the minimum memory when pc-dimm exists, is 512MB
(I have read some discussion mailing about pci hole, but I don't understand all
the things ;).
On a linux machine booting fine with -m 128 , it don't work with -m 128 -pcdimm
1024 ... for example.
