Hi, Vadim, According to comment 3 and comment 4, I only update virtio-win-prewhql-0.1-75 to virtio-win-prewhql-0.1-88, qemu-kvm is always qemu-kvm-1.5.3-66, found "stat-total-memory" is fixed. Whether the component of this bug is "virtio-win" and not "qemu-kvm"? Best regards Huiqing

So, you are absolutly right, the bug should be moved under virtio-win category. Best regards, Vadim.
Move status to Verified according to comment 3&4 Mike
