resovled it, this is because in the kernel 2.6.32; the 9pfs doesn't
implement the fsync function. just back port the code from higher
version, can resolve it.
like this patch

Title:
editing the file when mount the file system using 9pfs. it will report
fsync failed.
Status in QEMU:
New
Bug description:
I have get a fsync error when I use the 9pfs on the kvm guest. it
appears when I use vi editor and sysbench. I have not found the
reason yet. can you tell something about it? the attache is the
picture. and there is no any log which I can provide.
My qemu version is qemu-kvm-0.13.0, and my host linux distributions
is 2.6.32-431.el6.x86_64 and the guest vm is the same version which
enable 9pfs and 9pnet support. I use the string of "mount -t 9p -o
trans=virtio test_mount /tmp/shared/ -oversion=9p2000.L,posixacl" to
get the file system.
