While it's true that the default username is:
administrator@${SSO-Domain}
in majority of cases the ${SSO-Domain} is "vsphere.local". But
our code (and what virsh displays then) says it's just
"administrator".
This is wrong also from a different POV: the username must
contain the suffix no matter what and our default suggests
otherwise.

The lookups in esx_vi work a bit differently that we are used to. The filters
(travelsalSpec and selectSet) choose how to look up the objects, but given a
root object the lookup lists all the objects of a requested type inside it as
well as the root object itself. We then go through the results and find the one
which has the same name as was requested. However in a case with nested folders
of a same name this could break when the first returned object in the list is
the parent folder as we'd select it only based on the name. To avoid this also
add a check that the candidate we are trying to pick is not exactly the same
object (reference) as the root object.

Historically, we declared pointer type to our types:
typedef struct _virXXX virXXX;
typedef virXXX *virXXXPtr;
But usefulness of such declaration is questionable, at best.
Unfortunately, we can't drop every such declaration - we have to
carry some over, because they are part of public API (e.g.
virDomainPtr). But for internal types - we can do drop them and
use what every other C project uses 'virXXX *'.

The order in which virNetworkUpdate() accepts @section and
@command arguments is not the same as in which it passes them
onto networkUpdate() callback. Until recently, it did not really
matter, because calling the API on client side meant arguments
were encoded in reversed order (compared to the public API), but
then on the server it was fixed again - because the server
decoded RPC (still swapped), called public API (still swapped)
and in turn called the network driver callback (with reversing
the order - so magically fixing the order).
Long story short, if the public API is called even number of
times those swaps cancel each other out. The problem is when the
API is called an odd numbed of times - which happens with split
daemons and the right URI. There's one call in the client (e.g.
virsh net-update), the other in a hypervisor daemon (say
virtqemud) which ends up calling the API in the virnetworkd.
The fix is obvious - fix the order in which arguments are passed
to the callback.
But, to maintain compatibility with older, yet unfixed, daemons
new connection feature is introduced. The feature is detected
just before calling the callback and allows client to pass
arguments in correct order (talking to fixed daemon) or in
reversed order (talking to older daemon).
Unfortunately, older client talking to newer daemon can't be
fixed. Let's hope that it's less frequent scenario.

The ESX implementation of virConnectListAllDomains() follows
pretty much implementations in other drivers: it has local array
of virDomainPtr-s which (if requested by caller) is filled by
actual domains or not (if the caller is interested only in the
count of domains).
Anyway, in case of the former, the passed @domains argument is
set to the local array, which is then set to NULL to prevent it
from freeing under cleanup label. Pretty standard pattern.
Except, the local array is set to NULL always. Even if the local
array is not stolen. Fortunately, this doesn't lead to a memory
leak, because if caller is not interested in the array, none is
allocated. But it doesn't set good example and also breaks my
spatch rules.

theory the caller of the function might rely on "object" (the free

only called from a couple places each, and in all cases the pointer
that is passed is a local variable, and goes out of scope almost
immediately after calling the Free function, so it is safe to change
