If your libvirt is built yourself, you should enable dtrace by
`--with-dtrace`(version<6.7.0) or `-Ddtrace=enabled`(version>=6.7.0). See
https://libvirt.org/kbase/systemtap.html

Since you mentioned your libvirt is installed by apt, the dtrace is enabled
or not depending on whether the package builder enables dtrace or not when
building the libvirt package. For debian, you can check the libvirt build
result of your libvirt version(
https://buildd.debian.org/status/logs.php?pkg=libvirt). If there is
`--with-dtrace` or `-Ddtrace=enabled` in the build result, it usually means
the libvirt dtrace is enabled.
