Haven't used 9pfs in a while.
I thought these patches are a good time to play with it some more.
I have encountered two issues.
What I'm doing:
host: qemu a75143eda2ddf581b51e96c000974bcdfe2cbd10.
/scm/qemu/x86_64-softmmu/qemu-system-x86_64 -enable-kvm -m 1g -cpu kvm64
-smp 2 f20-x64.qcow2 -netdev user,id=foo -redir tcp:8022::22 -device
virtio-net,netdev=foo -serial stdio -fsdev
local,security_model=none,id=fsdev0,path=/lib/modules/ -device
virtio-9p-pci,id=fs0,fsdev=fsdev0,mount_tag=libmodulesshare -fsdev
local,security_model=none,id=fsdev1,path=/boot -device
virtio-9p-pci,id=fs1,fsdev=fsdev0,mount_tag=bootshare -no-reboot
-snapshot
guest: Fedora 20
added this in /etc/fstab:
bootshare /share/boot 9p trans=virtio,version=9p2000.L 0 0
libmodulesshare /share/lib/modules 9p trans=virtio,version=9p2000.L 0 0
I have encountered two issues:
1. mount failure on boot
If I try to mount on boot through fstab, I get:
[ 2.270157] 9pnet: Could not find request transport: virtio
[ 2.270158] 9pnet: Could not find request transport: virtio
If I then re-try mount, it succeeds immediately!
Some kind of dependency issue?
2. files immediately in the mounted directory aren't visible on the
guest under /share/boot.
For example, files under /boot on host are not visible
on guest, files under child directories seem visible.
Strange.
