10# @GenericError: this is used for errors that don't require a specific error

13# @CommandNotFound: the requested command has not been found
14#
15# @DeviceEncrypted: the requested operation can't be fulfilled because the
16# selected device is encrypted
17#
18# @DeviceNotActive: a device has failed to be become active
19#
20# @DeviceNotFound: the requested device has not been found
21#
22# @KVMMissingCap: the requested operation can't be fulfilled because a

33# LostTickPolicy:
34#
35# Policy for handling lost ticks in timer devices.
36#
37# @discard: throw away the missed tick(s) and continue with future injection
38# normally. Guest time may be delayed, unless the OS has explicit
39# handling of lost ticks
40#
41# @delay: continue to deliver ticks at the normal rate. Guest time will be
42# delayed due to the late tick
43#
44# @merge: merge the missed tick(s) into one tick and inject. Guest time
45# may be delayed, depending on how the OS reacts to the merging
46# of ticks
47#
48# @slew: deliver ticks at a higher rate to catch up with the missed tick. The
49# guest time should not be delayed once catchup is complete.

57# BiosAtaTranslation:
58#
59# Policy that BIOS should use to interpret cylinder/head/sector
60# addresses. Note that Bochs BIOS and SeaBIOS will not actually
61# translate logical CHS to physical; instead, they will use logical
62# block addressing.
63#
64# @auto: If cylinder/heads/sizes are passed, choose between none and LBA
65# depending on the size of the disk. If they are not passed,
66# choose none if QEMU can guess that the disk had 16 or fewer
67# heads, large if QEMU can guess that the disk had 131072 or
68# fewer tracks across all heads (i.e. cylinders*heads<131072),
69# otherwise LBA.
70#
71# @none: The physical disk geometry is equal to the logical geometry.
72#
73# @lba: Assume 63 sectors per track and one of 16, 32, 64, 128 or 255
74# heads (if fewer than 255 are enough to cover the whole disk
75# with 1024 cylinders/head). The number of cylinders/head is
76# then computed based on the number of sectors and heads.
77#
78# @large: The number of cylinders per head is scaled down to 1024
79# by correspondingly scaling up the number of heads.
80#
81# @rechs: Same as @large, but first convert a 16-head geometry to
82# 15-head, by proportionally scaling up the number of
83# cylinders/head.
