https://bbs.archlinux.org – Samba server inside KVM -- that's neat Have you guys tried -virtfs option (http://wiki.qemu.org/Documentation/9psetup)? This uses a plan9 filesystem to share a folder (any size) between guest and host. E.g.qemu-kvm -hda $1 -net nic,model=virtio \ -net user,hostfwd=tcp:127.0.0.1:15000-:22 -vga std \ -usbdevice tablet -device intel-hda -device hda-duplex -m 512 \ -virtfs local,id=exp1,path=/home/quarantine/shared_dir,security_model=mapped,mount_tag=virtfsIt's fast enough for me even w/o virtio modules inside guest...
