Synopsis:

vdev wdt-ib700 options

Options:

action [dump,]terminate|nmi

Specify what to do when the watchdog timer triggers:

  • dump – generate a guest dump, if the global option dump has been specified for the guest (see “dump” in this chapter, and “Getting a guest dump” in the “Monitoring and Troubleshooting” chapter)
  • nmi – send an edge on the interrupt line to which the device is connected
  • terminate – terminate the guest
intr intr
Specify the interrupt number on which to send an interrupt if the watchdog is configured to generate an interrupt.
loc addr
The base address of the registers in guest-physical memory (default space is io:). The value specified for addr must be the same as the value specified for the guest wdtkick's -a option.
If this option isn't specified, the configuration assumes the default address: 0x441.

For a list of options available to all vdevs, see “Common vdev options” at the beginning of this chapter.
