+qemu-kvm -m bigger 4096 aborts with 'Bad ram offset'
+
+When I try to start a virtual machine (x86_64 guest on a x86_64 host that has 32GB memory, using kvm_amd module, both host and guest running linux-2.6.39 kernels) with "qemu-system-x86_64 -cpu host -smp 2 -m 4096 ...", shortly after the guest kernel starts, qemu aborts with a message "Bad ram offset 11811c000".
+
+With e.g. "-m 3500" (or lower), the virtual machine runs fine.
+
+I experience this both using qemu-kvm 0.14.1 and a recent version from git

+
+After updating from the QEMU that came with Ubuntu 11.04 to 070411-1ubuntu2 version, I am seeing the bad ram offset error, also.  If I drop the memory for the guest (which is Windows 7 Pro 64-bit) from 4 GB to 3300MB, the error goes away.
+
+Host machine has an AMD Opteron 6128 with 32GB RAM and is running the 64 bit version of Ubuntu 11.04 updated to current versions as of November 
+
+Can you still reproduce this issue with the latest version of QEMU?
