Tracing the Interaction Between dom0 and the Hypervisor

Due to the isolation of the hypervisor from dom0, there is currently no way to apply DTrace directly to the hypervisor. There is an xpv DTrace provider that allows you to trace the interaction between dom0 and the hypervisor.

To list the available DTrace probes, use the following command line:

# dtrace -l -i 'xpv:::'

To enable all probes, use the following command line

# dtrace -n 'xpv::: {}'
