Title:
  virtio: trying to map MMIO memory

Status in QEMU:
  New

Bug description:
  Qemu host is Core i7, running Linux.  Guest is Windows XP sp3.
  Often, qemu will crash shortly after starting (1-5 minutes) with a statement 
"qemu-system-x86_64: virtio: trying to map MMIO memory"
  This has occured with qemu-kvm 0.14, qemu-kvm 0.14.1, qemu-0.15.0-rc0 and 
qemu 0.15.0-rc1.
  Qemu is started as such:
  qemu-system-x86_64 -cpu host -enable-kvm -pidfile /home/rick/qemu/hds/wxp.pid 
-drive file=/home/rick/qemu/hds/wxp.raw,if=virtio -m 768 -name WinXP -net 
nic,model=virtio -net user -localtime -usb -vga qxl -device virtio-serial 
-chardev spicevmc,name=vdagent,id=vdagent -device 
virtserialport,chardev=vdagent,name=com.redhat.spice.0 -spice 
port=1234,disable-ticketing -daemonize -monitor 
telnet:localhost:12341,server,nowait
  The WXP guest has virtio 1.1.16 drivers for net and scsi, and the most 
current spice binaries from spice-space.org.
