The first PR(#1176) intended to solve #CLOUDSTACK-9025 was only tackling the problem for CloudStack deployments that use single hypervisor types (restricted to XenServer). Additionally, the lack of information regarding that solution (poor documentation, test cases and description in PRs and Jira ticket) led the code to be removed in #1124 after a long discussion and analysis in #1056. That piece of code seemed logicless (and it was!). It would receive a hostId and then change that hostId for other hostId of the zone without doing any check; it was not even checking the hypervisor and storage in which the host was plugged into.
The problem reported in #CLOUDSTACK-9025 is caused by partial snapshots that are taken in XenServer. This means, we do not take a complete snapshot, but a partial one that contains only the modified data. This requires rebuilding the VHD hierarchy when creating a template out of the snapshot. The point is that the first hostId received is not a hostId, but a system VM ID(SSVM). That is why the code in #1176 fixed the problem for some deployment scenarios, but would cause problems for scenarios where we have multiple hypervisors in the same zone. We need to execute the creation of the VHD that represents the template in the hypervisor, so the VHD chain can be built using the parent links.
This commit changes the method com.cloud.hypervisor.XenServerGuru.getCommandHostDelegation(long, Command). From now on we replace the hostId that is intended to execute the “copy command” that will create the VHD of the template according to some conditions that were already in place. The idea is that starting with XenServer 6.2.0 hotFix ESP1004 we need to execute the command in the hypervisor host and not from the SSVM. Moreover, the method was improved making it readable and understandable; it was also created test cases assuring that from XenServer 6.2.0 hotFix ESP1004 and upward versions we change the hostId that will be used to execute the “copy command”.
Furthermore, we are not selecting a random host from a zone anymore. A new method was introduced in the HostDao called “findHostConnectedToSnapshotStoragePoolToExecuteCommand”, using this method we look for a host that is in the cluster that is using the storage pool where the volume from which the Snaphost is taken of. By doing this, we guarantee that the host that is connected to the primary storage where all of the snapshots parent VHDs are stored is used to create the template.
Consider using Disabled hosts when no Enabled hosts are found

This commit implements basic Security Grouping for KVM in
Basic Networking.
It does not implement full Security Grouping yet, but it does:
- Prevent IP-Address source spoofing
- Allow DHCPv6 clients, but disallow DHCPv6 servers
- Disallow Instances to send out Router Advertisements
The Security Grouping allows ICMPv6 packets as described by RFC4890
as they are essential for IPv6 connectivity.
Following RFC4890 it allows:
- Router Solicitations
- Router Advertisements (incoming only)
- Neighbor Advertisements
- Neighbor Solicitations
- Packet Too Big
- Time Exceeded
- Destination Unreachable
- Parameter Problem
- Echo Request
ICMPv6 is a essential part of IPv6, without it connectivity will break or be very
unreliable.
For now it allows any UDP and TCP packet to be send in to the Instance which
effectively opens up the firewall completely.
Future commits will implement Security Grouping further which allows controlling UDP and TCP
ports for IPv6 like can be done with IPv4.
Regardless of the egress filtering (which can't be done yet) it will always allow outbound DNS
to port 53 over UDP or TCP.

Removed unnecessary code from getGuestOsType in CitrixResourceBaseConsidering that all mapping of Guest OS Names to their respective hypervisor compatible types is made thorugh accessing a database, we've decided to remove a bit of code in the XcpOssResource class which was doing that same thing for 2 different OS's (both of which ARE in the database). That has led us to a bunch of unused parameters in the getGuestOsType method from its superclass, which we've also decided to remove. Test cases were added for four different possibilities for the platformEmulator String: one for a null String, one for a blank String, one for an empy String and one for a random case with a valid String.

CLOUDSTACK-9231: Root volume migration from one primary to another primary storage within the same cluster is failing
This situation arises when there are two management server accessing the same database.
When the migration request comes the command is forwarded from one management server to another because
the host is owned by the second management server. So, serialization of map from one to another fails.
This is fixed by converting the maps to lists.
Create test cases to getPatchFilePath method and class names changed In this commit we created tests cases for the respective classes in package com.cloud.hypervisor.xenserver.resource.
We added test cases to check the implementation of com.cloud.hypervisor.xenserver.resource.CitrixResourceBase.getPatchFiles. Therefore, we test in a more comprehensive way the tests that already exist to check the code of com.cloud.hypervisor.xenserver.resource.CitrixResourceBase.getPatchFilePath.
We added a new abstract class, called com.cloud.hypervisor.xenserver.resource.CitrixResourceBaseTest.java
This class has two tests methods:
* com.cloud.hypervisor.xenserver.resource.CitrixResourceBaseTest.testGetPathFilesExeption(CitrixResourceBase), this method tests if the getPatchFilePath() method throws the com.cloud.utils.exception.CloudRuntimeException.CloudRuntimeException when the com.cloud.utils.script.Script.findScript(String, String) return a null value;
* com.cloud.hypervisor.xenserver.resource.CitrixResourceBaseTest.testGetPathFilesListReturned(CitrixResourceBase), this method tests the correct return value from getPatchFilePath() method, basically, verify if the returned list contain the file with the same absolute path that was retrieved from the findScript method.
We also changed the name of those test classes, the change was basically remove the Path word from the name of classes.

Storage motion of vm across clusters/xenserver-pools fails in a
clustered management server setup. In xen storage motion we have to send
a migrate_receive command to the destination host, followed by
migrate_send command to the source host. The sr and network detials of
the destination host have to be passed in migrate_send command on the
source. While migrating across clusters the source and destination
resources are seperate objects. To pass this information across
resources we have to send seperate migrate with storage receive and send
commands to the resource. In a clustered ms setup these commands may
have to be forwarded to another ms as the resource may be owned by it.
The serilization of the command and answer objects fails in such case as
it doesn't understand the xapi sr and network objects. Made a change to
serialize these objects in the resource layer and pass the around as
strings in the command and answer objects. Reviewed-By: Likitha
@cristofolini comments:
Removed unnecessary duplicated code by having the body of the
getPatchFiles method only in the
CitrixResourceBase superclass. Given that all of its implementations
consisted of the same code
except for the path which contains the necessary file for that
implementation. An abstract method
getPatchFilePath was created in the CitrixResourceBase superclass so
that each implementation may
return the path containing the specific file needed by that
implementation.
Test cases were created for each implementation, simple as they may be.
One assert is made to verify
that the path returned by each implementation corresponds to the path
that was previously specified
on each getPatchFiles implementation.
removed trailing whitespace
- Adding more unit tests as suggested by Daan and Rajani.
- Mocking SshHelper and the Script classes, used by Citrix and Libvirt resources respectively.
- 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
Maven was bulding the project and executing the tests just fine because it uses "-sourcepath". However,
with IDEs and javac it would fail.

In the executeRequest I needed to keep the following:
