Does the SDK logging ever produce anything that would be useful when
troubleshooting libvirt ?

If so, you might be better to protect this with

    if (virGetEnvBlockSUID("LIBVIRT_PARALLELS_DEBUG") == NULL)
        PrlApi_SwitchConsoleLogging(0);

IOW, so people can do

  LIBVIR_PARALLELS_DEBUG=1 virsh ....

if they need to see debugging info

Daniel
