vdev progress
Report when a guest accesses an address in guest-physical memory, or attempts to execute specific instructions
Synopsis:
vdev progress options
Options:
- cpuid instr
- x86 only. Generate a report whenever the guest executes a
CPUID
instruction with the EAX equal to the value specifed by instr. - full
- Generate a full register dump on each reference.
- loc addr
- Report when the guest reads or writes the guest-physical address specified by addr.
- smc instr
- ARM only. Generate a report whenever the guest executes an
SMC
instruction with the immediate value specified by instr.
For a list of options available to all vdevs, see Common vdev options
at the beginning of this
chapter.
Description:
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).
