 |`expose-acl` |Enables ACL passthrough; implies `expose-xattr`. Supported only on compatible filesystems. |`0`
 |`expose-xattr` |Enables xattr passthrough; redundant if `expose-acl` is `1`. |`0`
 |`direct-io` |Enables support for the `O_DIRECT` flag. May degrade performance, but is useful if applications perform their own caching. |`0`
+|`thread-pool-size` |Controls the maximum number of worker threads used by virtiofsd to handle requests. Adjust for performance tuning. `0` disables the thread pool. |`0`
+|`readonly` | Prevent the guest from writing. This will not make the mount read-only. For example, the access time will still be updated upon access. |`0`
