+# vhost-block readonly feature test plan
+
+## Objective
+Vhost block controllers can be created with readonly feature which prevents any write operations on this device.
+The purpose of this test is to verify proper operation of this feature.
+
+## Test cases description
+To test readonly feature, this test will create normal vhost-blk controller with NVMe device and on a VM it will
+create and mount a partition to which it will copy a file. Next it will poweroff a VM, remove vhost controller and
+create new readonly vhost-blk controller with the same device.
+
+## Test cases
+
+### blk_ro_tc1
+1. Start vhost
+2. Create vhost-blk controller with NVMe device and readonly feature disabled using RPC
+3. Run VM with attached vhost-blk controller
+4. Check visibility of readonly flag using lsblk, fdisk
+5. Create new partition
+6. Create new file on new partition
+7. Shutdown VM, remove vhost controller
+8. Create vhost-blk with previously used NVMe device and readonly feature now enabled using RPC
+9. Run VM with attached vhost-blk controller
+10. Check visibility of readonly flag using lsblk, fdisk
+11. Try to delete previous file
+12. Try to create new file
+13. Try to remove partition
+14. Repeat steps 2 to 4
+15. Remove file from disk, delete partition
+16. Shutdown VM, exit vhost
