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.
