In situations where libvirt lost the storage pool the KVM Agent will re-create the
storage pool in libvirt.
This could be then libvirt is restarted for example.
The object returned internally was missing essential information like the sourceDir
aka the Ceph pool, the monitor IPs, cephx information and such.
In this case the first operation on this newly created pool would fail. All operations
afterwards would succeed.
to get nic info of 0.0.0.0. To get it, it iterates through all nics and return the last NIC in
the list if it doesn't match with any IP address. In case last NIC doesn't have unicastAddress,
Hyper-V agent will fail to start. We don't need IP address during initialization. It get
initialized with startupcommand later.
Adding missing KVM mappings
Testing Done:
Local testing with removing CentOS mapping and launch a VM.

last VM from the VPC is deleted on a host
OVS distributed routing: ensure bridge is deleted when last VM from the
VPC is deleted on a host. This fix ensures that bridge is
destroyed.
the folder column. For an smb share the smb credentials are in the query string of the path.
Before adding the path, smb shares query string should be cleaned up.

This patch is for XenServer.
1. Local testing on XenServer 6.0.2
2. Successfully got up system VMs
3. Successfully created a CentOS VM
4. Created VM snapshot and reverted to snapshot
5. Manipulated guest_os_hypervisor table for mapping, and checked for correct propagation of platform emulator.

that case cloudstack was not doing anything and not updating the state of the vms to stopped.
Now the agent returns empty list of hostvmstatereport. Management server will then update the
vm state to stopped (instead of not acting upon the return state).
Check if switch name detected from traffic label for management, storage, control traffic is null before falling back to default value.

Since we use qemu-img to copy from RBD to Secondary Storage we no
longer have to force to RAW images, but can stick with QCOW2
When the snapshot backups are QCOW2 format they can easily be deployed
again when restoring from a backup

In case some environments has different performance or we found some commands
would took too long to execute, one global configuration item is introduced to
specify "time out in seconds per one command in aggregation commands".
By default it's 3 seconds. If admin feel it's too long, it can be adjust to as
low as 1 seconds, which runs still well in my machine.
Added a new flag 'checkBeforeCleanup' to StopCommand based on which check is done to see if VM is running in HV host.
If VM is running then in this case it is not stopped and the operation bails out.
Also modified the MS code to call the StopCommand with appropriate value for the flag based on the context.
Currently it is only set to 'true' when called from the new vmsync logic based on powerstate of VM. For rest it
is set to 'false' meaning no change in behaviour.
This reduces the amount of time and storage it takes dramatically. We no longer
do a full copy, but a sparse copy. The destination image is still in RAW
format, but we only copy over used blocks.
Qemu is also better in doing this then us doing it in Java code.
This saves the step of writing to a temporary image in /tmp first before
writing to RBD.
This is possible due to a new version in librbd. With the rbd_default_format
setting we can now force qemu-img to create format 2 RBD images.
This is available since Ceph version 0.67.5 (Dumpling).
Otherwise a RBDException will be thrown with the message that the snapshot
isn't protected.
