There are common options that apply to more than one type of vdev.
These common options are described below. If, however, an option is
also described in the reference for an individual vdev, refer to that description.
- hostvector vector_number
- Applies only to PIC vdevs. This option
sets the associated host vector number of the first line of the current
vdev. This number is used by InterruptAttach() and
InterruptAttachEvent() (see the
QNX Neutrino C
Library Reference). The PIC input lines that follow are
sequentially assigned to host vector numbers.
- This option is needed only if any of the PIC guest interrupts will be marked
as pass-through. If hostvector isn't specified, its value
defaults to the previous PIC device's hostvector number,
plus this previous device's number of lines. If this is the first PIC
specified, hostvector defaults to 0
(zero).
- intr
guest_intr
- The guest interrupt of the current vdev is set to
guest_intr, in two parts, separated by a colon (e.g.,
intr gic:40).
- For PCI devices that use an interrupt, if you don't set a number for
guest_intr, this number is automatically assigned.
For non-PCI devices (e.g., MMIO devices), you must set this option.
- For more information, see “Guest interrupts” in the “Configuration” chapter.
- loc
location_spec
- The current vdev has its location in the guest-physical address set to
location_spec. For non-PCI devices (e.g., MMIO
devices), you must set this option.
- log
filter[,filter,...]
output_dest
- The message types to output and their output destination.
This option lets you override the VM's global logging for the current vdev, so you can see
certain message types related to the vdev's activity.
The option's argument has two tokens: The first is a comma-separated list of the
severity levels of the messages to be output. The possible severity levels are:
- fatal
- internal
- error
- warning
- info
- debug
- verbose
The second token is the destination, which is one of: stdout, stderr,
slog, and none. This last setting allows you to disable outputting
certain message types.
You may specify as many
log options as you like, but if you specify
conflicting destinations for a given severity level, the latter (rightmost) option takes
precedence. For example, if you have the following:
log fatal,internal,error,warn stdout
log warn none
The second option setting cancels the logging of warnings that was set by the first
setting.
The log and logger options work similarly,
so for more details about the syntax and semantics of this option, see the
logger entry in the “VM Configuration Reference” chapter.
- name
name
- An optional name used by the vdev for further configuration. Currently
this option is relevant only for peer vdevs, such as virtio-net,
and for PIC devices. For certain PIC devices, the name may be referenced in
guest_intr specifications to say that the device is
connected to a given PIC input line.
- See “VM configuration file example” for details on how
the name option relates to specific PIC hardware. See vdev virtio-net
in this chapter for more information about using the
name option when configuring peers in a network.
