Mein Problem ist, dass Netzwerkgeräte in meinem Gerätebaum nicht sehr stabil sind. Daher dachte ich, der beste Weg, um einen Ordner zwischen qemu und dem Hostsystem freizugeben, ist, dass Sie dasselbe Bild ohne Cache auf beiden Seiten mounten, aber die Option -hda auf qemu nicht die hd verfügbar in / dev /.
Hier ist der Befehl, den ich ausführe.
./qemu-xilinx/arm-softmmu/qemu-system-arm -M xilinx-zynq-a9 -m 1024 -serial null -serial mon:stdio -dtb resources/devicetree.dtb -kernel resources/zImage -initrd resources.qemu/ramdisk.img -nographic -s
Die Frage ist also: Gibt es eine Möglichkeit, das Netzwerk zu umgehen und dennoch ein gemeinsames Verzeichnis zwischen qemu und dem Host zu haben?
EDIT: Ich habe mit kompiliert
./configure --target-list="arm-softmmu,microblazeel-softmmu" --enable-fdt --disable-kvm --enable-virtfs
was alles Notwendige ermöglichen sollte. Allerdings wenn ich renne
./qemu-xilinx/arm-softmmu/qemu-system-arm -M xilinx-zynq-a9 -m 1024 -serial null -serial mon:stdio -dtb /homes/cperivol/Sandbox/xilinx-zynq-bootstrap/resources/devicetree.dtb -kernel /homes/cperivol/Sandbox/xilinx-zynq-bootstrap/resources/zImage -initrd /homes/cperivol/Sandbox/xilinx-zynq-bootstrap/resources.qemu/ramdisk.img -nographic -s -fsdev local,path=/homes/cperivol/Sandbox/xilinx-zynq-bootstrap/qemu-sandbox/,security_model=passthrough,id=host0 -device virtio-9p-pci,fsdev=host0,mount_tag=host_tag0
oder
./qemu-xilinx/arm-softmmu/qemu-system-arm -M xilinx-zynq-a9 -m 1024 -serial null -serial mon:stdio -dtb resources/devicetree.dtb -kernel resources/zImage -initrd resources.qemu/ramdisk.img -nographic -s -virtfs local,path=/homes/cperivol/Sandbox/xilinx-zynq-bootstrap/qemu-sandbox/,mount_tag=host0,security_model=passthrough,id=host0
Ich bekomme
No 'PCI' bus found for device 'virtio-9p-pci'
Vielleicht sollte ich auch erwähnen, dass arm-softmmu/config-devices.mak
es CONFIG_PCI=y
die Objektdateien von pci gibt und dass sie sich tatsächlich dort befinden hw/pci
.
EDIT2: Betrachtet man den von qemu gesicherten Gerätebaum, enthält das emulierte System keinen PCI-Bus.
