| Thread-topic: | [Xen-devel] [Patch] Qemu map cache |
On IA32 host or IA32 PAE host, at present, generally, we can't create an HVM guest with more than 2G memory, because generally it's almost impossible for Qemu to find a large enough and consecutive virtual address space to map an HVM guest's whole physical address space. The attached patch fixes this issue using dynamic mapping based on little blocks of memory. -- Dexuan Cui Signed-off-by: Jun Nakajima <jun.nakajima@xxxxxxxxx> Signed-off-by: Dexuan Cui <dexuan.cui@xxxxxxxxx>
