Change OUT instruction to use dst instead of src, so we can
reuse those code for all out instructions.

Recently seabios implement vcpu hotplug infrastructure.
During test, we found qemu-kvm has a bug result in guestos shutdown when vcpu

This patch is to fix the bug, mark bus->allow_hotplug as 1 after qdev_hotplug

Hi,
we today saw a Win2k8 VM with first device IDE and second device SCSI crash
reprocably during boot.
Win2k8 32-bit Server was installed with IDE only. The second SCSI device was
added later.
Here is the output and commandline:
Aug 5 20:42:55 172.21.59.142 exec: /usr/bin/qemu-kvm-0.12.4 -n
Thanks Avi,
I am trying to reproduce this on another setup, and do not see the issue.
My understanding is to run KVM + Qemu, I only need to install KVM modules,
and Qemu does not need to be modified. Is that correct?
I see
[r...@ipg-virt01 anjali]# lsmod | grep kvm
kvm_intel 87016 0
qemu supports up to UIO_MAXIOV s/g so we have to match that.
Apparently windows guests rely on this (more precisely,
they want to fill all of vq with s/g entries of a single
descriptor).
Allocate indirect and log arrays dynamically to avoid
using too much contigious memory.
