[Bug 1355885] [NEW] VMwareVCDriver NotImplementedError

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

I'm using devstack and after a recent update (using stack.sh with
RECLONE=yes), nova compute isn't starting anymore.

I'm using the compute_driver =  vmwareapi.VMwareVCDriver  and I get the
following exception:

It appears to be due to the fix for bug #1346637
Change-Id: I718fc0ee67dbd625af00c20fa4e34b8a35015437
commit 1deb31f85a8f5d1e261b2cf1eddc537a5da7f60b

The change looks like it removed the VMwareESXDriver which was the
parent class for VMwareVCDriver.

This means that the init_host() method that was previously implemented
by VMwareESXDriver is now not implemented anymore by VMwareVCDriver.  Is
there some new configuration I'm missing or is this a real problem?

For now to get it working I've copied the old init_host() and
cleanup_host() methods over - not sure if others are missing as well,
but it's enough to get Nova compute to start.  Attaching the patch for
this for reference.  Apologies if it's not in the correct format, this
is very new to me.
