the "type hint" is BDRV_TYPE_CDROM or BDRV_TYPE_FLOPPY.

scsi, xen, or none.

if=ide and if=scsi work, because the type hint makes it a CD-ROM.
if=xen likewise, I think.

For the same reason, if=none works when it's used by ide-drive or
scsi-disk.  For other guest devices, there are problems:

* fdc: you can't change virtual media

    Device 'foo' is not removable

  unless you add media=cdrom, but that makes it readonly.

* virtio: if you add media=cdrom, you can change virtual media.  If
  you eject, the guest gets I/O errors.  If you change, the guest sees
  the drive's contents suddenly change.

* scsi-generic: if you add media=cdrom, you can change virtual media.

Currently all user-defined ones have a DriveInfo, because the only way

Fortunately, the device models are perfectly happy with
BlockDriverState, except for two places: ide_drive_initfn() and
scsi_disk_initfn() need to check the DriveInfo for a serial number set

Monitor: handle optional '-' arg as a bool

Historically, user monitor arguments beginning with '-' (eg. '-f')
were passed as integers down to handlers.

I've maintained this behavior in the new monitor because we didn't
have a boolean type at the very beginning of QMP. Today we have it
and this behavior is causing trouble to QMP's argument checker.

This commit fixes the problem by doing the following changes:

1. User Monitor

   Before: the optional arg was represented as a QInt, we'd pass 1
           down to handlers if the user specified the argument or
           0 otherwise

   This commit: the optional arg is represented as a QBool, we pass
                true down to handlers if the user specified the
                argument, otherwise _nothing_ is passed

2. QMP

   Before: the client was required to pass the arg as QBool, but we'd
           convert it to QInt internally. If the argument wasn't passed,
           we'd pass 0 down

   This commit: still require a QBool, but doesn't do any conversion and
                doesn't pass any default value

3. Convert existing handlers (do_eject()/do_migrate()) to the new way

   Before: Both handlers would expect a QInt value, either 0 or 1

   This commit: Change the handlers to accept a QBool, they handle the
                following cases:

                   A) true is passed: the option is enabled
                   B) false is passed: the option is disabled
                   C) nothing is passed: option not specified, use
                                         default behavior

14 years agonet: Fix VM start with '-net none'
Amit Shah [Tue, 15 Jun 2010 08:00:39 +0000 (13:30 +0530)]
net: Fix VM start with '-net none'

Commit 50e32ea8f31035877decc10f1075aa0e619e09cb changed the behaviour
for the return type of net_client_init() when a nic type with no init
method was specified. 'none' is one such nic type. Instead of returning
0, which gets interpreted as an index into the nd_table[] array, we
switched to returning -1, which signifies an error as well.

That broke VM start with '-net none'. Testing was only done with the
monitor command 'pci_add', which doesn't fail.

The correct fix would still be to return 0+ values from
net_client_init() only when the return value can be used as an index to
refer to an entry in nd_table[]. With the current code, callers can
erroneously poke into nd_table[0] when -net nic is used, which can lead
to badness.

However, this commit just returns to the previous behaviour before the
offending commit.
