When trying to load sysdig-probe in linux-kvm, I get the following
errors:
[ 1566.950603] sysdig_probe: Unknown symbol tracepoint_probe_unregister (err 0)
[ 1566.950810] sysdig_probe: Unknown symbol for_each_kernel_tracepoint (err 0)
[ 1566.950816] sysdig_probe: Unknown symbol tracepoint_probe_register (err 0)
That seems to be caused by the lack of CONFIG_TRACING and CONFIG_FTRACE in the
linux-kvm config.

Bionic, Linux-Kvm: 4.15.0-1043.43
The module appears to load, however it may be that the service itself still
does not start, there are no errors in the logs, just the following:

Will require some additional triage.
