Since enabling libvirt SASL authentication, the masakari instance
monitor fails to connect to libvirt. We see the following error in logs:
libvirt.libvirtError: authentication failed: Failed to start SASL
negotiation: -4 (SASL(-4): no mechanism available: No worthy mechs
found)
This change adds support for SASL authentication in Masakari instance
monitor.
