Public bug reported:
I'm using Ubuntu 16.04 amd64.
Host system executes command like:
qemu-system-x86_64 -initrd ./hyper-initrd.img -kernel ./kernel -m
512 -smp 1 -fsdev
local,id=virtio9p,path=`pwd`/rootfs,security_model=none -device virtio-
9p-pci,fsdev=virtio9p,mount_tag=share_dir
Qemu Intern system executes API like:
mkdir("/nfs", 0755);
mount("share_dir", "/nfs", "9p", MS_MGC_VAL| MS_NODEV,
"trans=virtio,cache=loose")
Then, external qemu-system_x86-64 crashes!
