This patch adds an internal function vmwareUpdateVMStatus to
update the real state of the domain. This function is used in
various places in the driver, in particular to detect when
the domain has been shut down by the user with the "halt"
command.
---
v2:
- Replace internal function vmwareGetVMStatus by vmwareUpdateVMStatus
- Improve vmrun list output parsing
- variable initialization and coding-style fixes
