-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 \

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


Comment 2 Vadim Rozenfeld 2021-07-13 05:59:13 UTC
please check with the lates drivers from build 204

Comment 6 xiagao 2021-07-21 10:14:51 UTC
Rename works with 204 version.
So change status to verify.
