[OpenSIPS-Users] Virtual_DB issue with NDBClUSTER

[Jeff Pyle]

I use Opensips with NDBCLUSTER, although not with db_virtual.  Seems to
work okay with db_mysql.  To keep things simple, each of my Opensips
machines (VMs, really) has a mysqld instance whose only role is to be a
front-end to the cluster.  I've tried it with CentOS RPMs, Debian (stable)
packages, and 7.1.x source from the MySQL site.  All okay.

Sorry, no further information on the virtual portion.
