I found that there is no sound in guests of Win7, WinXP and even
fedora. I searched the web to issue export QEMU_AUDIO_DRV=alsa
before starting the guest but no use. Anyone can help to fix it?
Host: CentOS 6.3 (64 bits)
Guest: Windows 7 (32 bits)/WinXP (32 bits)/Fedora 17 (64 bits)
Only change is adding Michael's ack. Thanks,
Alex

Enabled for all softmmu guests supporting PCI on Linux hosts. Note
that currently only x86 hosts have the kernel side VFIO IOMMU support
for this. PPC (g3beige) is the only non-x86 guest known to work.
ARM (veratile) hangs in firmware, others untested.

I can't see any reason for it, and the book3s_pr version doesn't have it.

This enables userspace to get and set all the guest floating-point
state using the KVM_[GS]ET_ONE_REG ioctls. The floating-point state
includes all of the traditional floating-point registers and the
FPSCR (floating point status/control register), all the VMX/Altivec
vector registers and the VSCR
The PAPR paravirtualization interface lets guests register three
different types of per-vCPU buffer areas in its memory for communication
with the hypervisor. These are called virtual processor areas (VPAs).
Currently the hypercalls to register and unregister VPAs are handled
by KVM in the
