qemu:virtio-net: Add additional MACs via a filter table (Alex Williamson)
Create a filter table and allow the guest to populate it with the
MAC class control commands. We manage the size and usage of the
filter table including enabling promiscuous and all-multi modes
as necessary. The guest should therefore assume the table is
infinite. Eventually this might allow us to bind directly to a
hardware NIC and manipulate a physical MAC filter.
The specifics of the TABLE_SET command are documented in
virtio-net.h. Separate buffers in the same command are used
for unicaste and multicast addresses for priority and
sychronization. With this we can export the VIRTIO_NET_F_CTRL_RX

Terminate emulation on memory allocation failure (Avi Kivity)
Memory allocation failures are a very rare condition on virtual-memory
hosts. They are also very difficult to handle correctly (especially in a

code paths.
This patch changes the qemu memory allocation routines to terminate emulation

VMware couples itself pretty tightly to the CPUID, so it's a good idea to emulate

nested virtualization.
