+The handling of read-only zones also differs between mount-time and run-time.
+If a read-only zone is found at mount time, the zone is always treated in the
+same manner as offline zones, that is, all accesses are disabled and the zone
+file size set to 0. This is necessary as the write pointer of read-only zones
+is defined as invalib by the ZBC and ZAC standards, making it impossible to
+discover the amount of data that has been written to the zone. In the case of a
+read-only zone discovered at run-time, as indicated in the previous section.

+The main ioctl to access SEV is KVM_MEM_ENCRYPT_OP. If the argument
+to KVM_MEM_ENCRYPT_OP is NULL, the ioctl returns 0 if SEV is enabled
+and ``ENOTTY` if it is disabled (on some older versions of Linux,
+the ioctl runs normally even with a NULL argument, and therefore will
+likely return ``EFAULT``). If non-NULL, the argument to KVM_MEM_ENCRYPT_OP

+ __u32 id;
+ __u64 data;
+ __u32 error;

+another struct containing arguments specific to command. The ``sev_fd``
+should point to a file descriptor that is opened on the ``/dev/sev``
+device, if needed (see individual commands).
+
+On output, ``error`` is zero on success, or an error code. Error codes
+are defined in ``<linux/psp-dev.h>`.

guests, such as launching, running, snapshotting, migrating and decommissioning.
