[Bug 1786683] [NEW] instance log with vmware fails

 

Public bug reported:

This happens on a fully updated Queens release using Ubuntu's Bionic
release.

Basically the vmwareapi/driver.py opens the log-file and passes it to
nova.privsep.path.last_bytes as argument.

However, nova.privsep.path.last_bytes expects a path and not a file-
handle. Thus it throws a TypeError exception.


Changing the vmwareapi/driver.py to call

```
read_log_data, remaining = nova.privsep.path.last_bytes(path, MAX_CONSOLE_BYTES)
```
instead, fixes the issue.

** Affects: nova
