...low that segment. For this reason, 0x413 is actually a better source than 0x40e to get the location of the real-mode trampoline. But it is even better to fetch the information from the multiboot structure, where the boot loader has placed the data for us already.

Windows SVVP tests requiring a HPET ACPI table is in my opinion not a valid reason to always expose that table - respective tests should be run with "hpet=1" in the guest config file. The problem here is that at least with qemu-traditional, which by default doesn''t appear to emulate a HPET, the advertising here can mislead an OS to believe that there actually is a usable HPET,

This series implements virtio-scsi queue steering, which gives performance improvements of up to 50% (measured both with QEMU and tcm_vhost backends). This version rebased on Rusty's virtio ring rework patches. We hope this can go into virtio-next together with the virtio ring rework pathes. V5: improving the grammar of 1/5 (Paolo) move the dropping of sg_elems to 'virtio-scsi: use
