You may still implement the API for other drivers too. The way we
addressed this problem in the past is to create new API and have the old
one call the new one. That's why we have "virSomething WithFlags()" APIs
- because simply when introducing virSomething() API we did not think of
adding flags. But if you then look how virSomething is implemented at
driver level (say qemu driver) then you will see virSomething() is a
very thin wrapper that calls virSomethingWithFlags(..., 0);.
For instance virDomainCreate() and virDomainCreateWithFlags() and
qemuDomainCreate() and qemuDomainCreateWithFlags().
So you will need to add a new API and then have the old call the new one
with sensible @source. Since the sensible value can differ among drivers
I guess we can have VIR_DOMAIN_HOSTNAME_SRC_DEFAULT which would mean
"hypervisor driver default as in the most sensible source chosen
automatically by driver".
