On NFS we write a heartbeat, but without those we can not safely
fence off a host.
If we fence without knowing about a heartbeat we can cause a split-brain situation.

- Make sure the new password replaces the old one in the queue
- Updated the patch files for XenServer
- Updated the script path on LibvirtComputing class
- Adding update_host_passwd to VRScripts
- Add implementation to CitrixUpdateHostPasswordCommandWrapper
- Improve testUpdateHostPasswordCommand() unit test on CitrixRequestWrapperTest
- Adding update_host_passwd.sh script
- Adding the host IP address as an instance variable on UpdateHostPasswordCommand
- Improving the Unit Test (LibvirtComputingResourceTest) to get it covering the new code
- Make sure doUpdateHostPassword() doesn't get called if flag is set to false
- Do not update XenServer hosts if the cluster ID is not informed
This closes#559
- Adding more unit tests as suggested by Daan and Rajani.
- Mocking SshHelper and the Script classes, used by Citrix and Libvirt resources respectively.
- Changed location of the update_host_passwd script
- Updated the patch files for XenServer
- Updated the script path on LibvirtComputing class
- Removed the hostIP from the LibvirtUpdateHostPasswordCommandWrapper execute() method
- Adding update_host_passwd to VRScripts
- Add accessor method to host password on CitrixResourceBase
- Add implementation to CitrixUpdateHostPasswordCommandWrapper
- Improve testUpdateHostPasswordCommand() unit test on CitrixRequestWrapperTest
- Add line to patch files on xenserver directory
Concerning the LibVirt change:
- I forgot to assing the return of the getDefaultHypervisorScriptsDir() method to the hypervisorScriptsDir variable
- Modifying the LibvirtUpdateHostPasswordCommandWrapper in order to execute the script on the host
- Adding the script path to LibvirtComputingResource
- Adding the host IP address as an instance variable on UpdateHostPasswordCommand
- Improving the Unit Test (LibvirtComputingResourceTest) to get it covering the new code
- Make sure the doUpdateHostPassword() method returns the result from the answer, not always true
- Added the LibvirtUpdateHostPasswordCommandWrapper class, which will handle the changes in the KVM agent
That's will be further implemented in the future. The command will avoid the agent to complain about Unsupported command
- Added a test to make sure the current implementation of the comment works
- If changes in the future, it will also require changes. In that way, we make sure nobody will break it

KVM hosts which are actuall up, but if their agents are shutdown should be put
in disconnected state. This would avoid getting the VMs HA'd and other commands
such as deploying a VM will exclude that host and save us from errors.
The improvement is that, we first try to contact the KVM host itself. If it fails
we assume that it's disconnected, and then ask its KVM neighbours if they can
check its status. If all of the KVM neighbours tell us that it's Down and we're
unable to reach the KVM host, then the host is possibly down. In case any of the
KVM neighbours tell us that it's Up but we're unable to reach the KVM host then
we can be sure that the agent is offline but the host is running.

Fixing typo on LibvirtRequestWrapper
- Replace linbvirtCommands by libvirtCommands on LibvirtRequestWrapper
Signed-off-by: Rohit Yadav <rohit.yadav@shapeblue.com>
This closes#255
- The test was okay, but when running in an environment where a /root/.ssh/id_rsa existed, it would return true then fail
- We now mock the calls to methods that return the key paths, instead of relying in the static variables
- Adding LibvirtNetworkElementCommandWrapper and LibvirtStorageSubSystemCommandWrapper
- 2 unit tests added
- KVM hypervisor plugin with 22.2% coverage
I also refactored the StorageSubSystemCommand interface into an abstract class
- Remove the pseudo-multiple-inheritance implementation
- The StorageSubSystemCommand was an interface, not related to the Command class
and its implementation were extending the Command class anyway. The whole structure is better now.
- Addin LibvirtPvlanSetupCommandWrapper
- 6 unit tests added
- KVM hypervisor plugin with 21% coverage
From the 6 tests added, 2 were extra tests to increase the coverage of the LibvirtStopCommandWrapper
- Increased from 35% to 78.7%
- Adding LibvirtCopyVolumeCommandWrapper
Refactoring the LibvirtUtilitiesHelper
- Changing method name
Did not add any test to this commit due to the refactor mentioned abot.
Will proceed and add the tests
i# Please enter the commit message for your changes. Lines starting
- Gave it a better, more suggestive, name since I now added other methods to the class.
- It makes easier to mock objects and get a better coverage of the classes
- Adding LibvirtBackupSnapshotCommandWrapper, LibvirtCreatePrivateTemplateFromVolumeCommandWrapper and LibvirtManageSnapshotCommandWrapper
- 3 unit tests added
- KVM hypervisor plugin with 18.3% coverage
Less tests added to those classes because the code is quite complex and way too long.
The tests added are just covering the new flow, to make sure it works fine. I will come back to those classes later.
