 anyway you have anyidea why it is working with kvm above 4giga and not
 with qemu??? can you look at how i did the mapping in qemu?

Kqemu is not compatible with 2G, does it change anything if you run
without kqemu?

Also the assembly versions of softmmu access functions would need
changing. To avoid that, you could try qemu on x86_64 or comment out
the line for ASM_SOFTMMU in target-i386/op.c.

i compiled it without Kqemu support.
i dont work with qemu emulator, but was working with kvm + qemu tested
on 32giga ram.

[Qemu-devel] adding support for above 2giga for qemu. ( include patchs )

2007-08-14 Thread Izik Eidus 
hey,
i have wrote a patch to qemu to allow it to run with above the 2giga 
limitations we have now.
i tested it on qemu that used kvm with 14giga of ram, and it was tested at 
other place with 32giga of ram to the guest ( 32bits, and 64bits).

the patch that i send here, is patch to qemu without kvm,
it include patch to the bochs bios, and patch to the qemu.
part of the patch to qemu fix the typedefs varibles to unsigned long, and it is 
based on patch i saw at this list
that target sparc.

for some reason the mapping that i do inside qemu with 
cpu_register_physical_memory dont work, and with this patchs
qemu could not work with more than 3.75giga of ram. ( with kvm it does 
working... )

this is request for comment, i probbley doing something wrong inside qemu, so 
anyone have idea how to solve it
please comment :)


anyway for to make it easy to run i put here compiled patched bios.

have fun! :-)
