This renames the type for HMP monitor commands and the tables holding the commands to make clear that they are related to HMP and to allow making them public later: * mon_cmd_t -> HMPCommand (fixing use of a reserved name, too) * mon_cmds -> hmp_cmds * info_cmds -> hmp_info_cmds Signed-off-by: Kevin Wolf <kwolf@redhat.com> Message-Id: <20190613153405.24769-7-kwolf@redhat.com> Reviewed-by: Markus Armbruster <armbru@redhat.com> [sortcmdlist() cleaned up to make checkpatch.pl happy] Signed-off-by: Markus Armbruster <armbru@redhat.com>

Commit changes to the disk images (if -snapshot is used) or backing files.

If the backing file is smaller than the snapshot, then the backing file will be

backing file to match the size of the smaller snapshot, you can safely truncate

it yourself once the commit operation successfully completes.

Remove host block device. The result is that guest generated IO is no longer

submitted against the host device underlying the disk. Once a drive has

been deleted, the QEMU Block layer returns -EIO which results in IO
|
|
errors in the guest for applications that are reading/writing to the device.

These errors are always reported to the guest, regardless of the drive's error
|
|
actions (drive options rerror, werror).

(qemu) change ide1-cd0 /path/to/some.iso
|

@var{read-only-mode} may be used to change the read-only status of the device.

It accepts the following values:
|

@table @var
|

@item retain
|
|
Retains the current status; this is the default.
|

Makes the device writable.
|

|
|
|
|
@example
|
|
(qemu) change vnc localhost:1
|
|
@end example
|
|
|
|
@item change vnc password [@var{password}]
|
|
|
|
Change the password associated with the VNC server. If the new password is not
|
|
supplied, the monitor will prompt for it to be entered. VNC passwords are only
|
|
significant up to 8 letters. eg
|
|
|
|
@example
|
|
(qemu) change vnc password
|

Add a match rule to the access control list, allowing or denying access.

The match will normally be an exact username or x509 distinguished name,

allow all users in the @code{EXAMPLE.COM} kerberos realm. The match will

normally be appended to the end of the ACL, but can be inserted

earlier in the list if the optional @var{index} parameter is supplied.
