Report when a guest accesses an address in guest-physical memory, or attempts to execute specific instructions
vdev progress options
For a list of options available to all vdevs, see Common vdev options at the beginning of this chapter.
The progress vdev can generate reports when any of the loc, smc, or cpuid conditions described above occurs.
For example, the following generates a report when a guest accesses the specified location in its guest-physical memory:
vdev progress loc 0xffff0000
Similarly, the following generates a report when a guest executes an SMC instruction with a value of 0x01:
vdev progress smc 0x01
The hypervisor outputs reports to whatever destination is specified by the logger option's info filter (see logger in the VM Configuration Reference chapter).
