Description of problem:
Boot up a Win2019 vm with virtio fs shared dir(nfs backend),try to create/rename/delete file or folders on the file system, hit a couple of errors.

Version-Release number of selected component (if applicable):
qemu-kvm-5.2.0-11.el9.x86_64
kernel-5.11.0-2.el9.x86_64
virtio-win-prewhql-0.1-197

How reproducible:
100%

Steps to Reproduce:
1.mount a nfs dir on host.
(host)mount 10.66.8.151:/home/nfs  /home/nfs_c
(nfs conf) /home/nfs *(rw,sync,no_root_squash)

2.start virtiofs daemon with shared dir on nfs mount dir
# /usr/libexec/virtiofsd --socket-path=/tmp/vhostqemu1 -o source=/home/nfs_c/virtiofs_test/ -d

3.boot up vm with vhost-user-fs-pci device
-chardev socket,id=char0,path=/tmp/vhostqemu1 \
-device vhost-user-fs-pci,chardev=char0,tag=myfs_11,bus=pci.11,queue-size=1024 \
-m 4G \
-object memory-backend-file,id=mem,size=4G,mem-path=/dev/shm,share=on \
-numa node,memdev=mem \

4.install viofs driver,register virtiofs service and start it
C:\> sc create VirtioFsSvc binpath="(your binary location)\virtiofs.exe" start=auto 
depend="WinFsp.Launcher/VirtioFsDrv" DisplayName="Virtio FS Service"

c:\> sc start VirtioFsSv

5.create and rename a file/folder on the shared volume(Z:)

6.delete a file/folder

After step 6, delete succeed, but a ".nfs0000000..." file is created after refresh the windows and can't create a file/folder any more.


Expected results:

Could you set DTM as it was set ITR to 8.5.0?

Thanks.

Rename works with 204 version.
So change status to verify.
