Hi all, Xen is not limited by the QEMU's virtual address space for the allocation of the guest RAM. So even with a QEMU 32bits, a Xen guest can have more than 4 GB of RAM.
With this serie, we will be able to run a guest with more than 4GB. The main point is to change ram_addr_t from ulong to uin64 when QEMU is configure with Xen. The second point is better register the memory in QEMU. Regards, Anthony PERARD (5): xen: Fix xen_enabled(). exec.c: Use ram_addr_t in cpu_physical_memory_rw(...). cpu-common: Have a ram_addr_t of uint64 with Xen. xen: Fix the memory registration to reflect of what is done by Xen. vl.c: Check the asked ram_size later. cpu-common.h | 8 ++++++++ exec.c | 13 +++++++------ hw/xen.h | 2 +- vl.c | 14 ++++++++------ xen-all.c | 23 +++++++++++++++-------- 5 files changed, 39 insertions(+), 21 deletions(-) -- Anthony PERARD
