The additional queues can enhance the performance of the VirtIO SCSI disk
and it is recommended to set this to the amount of vCPUs a Instance is assigned.
The optional queues attribute specifies the number of queues for the
controller. For best performance, it's recommended to specify a value matching
the number of vCPUs. Since 1.0.5 (QEMU and KVM only)

Added dummy and lo devices to be treated as a normal bridge slave devs.
Fixes#2998
Added two more device names (lo* and dummy*). Implemented tests. Code was refactored.
Improved paths concatenation code from "+" to Paths.get.
If a host has many routes this can be a magnitude faster then printing
all the routes and grepping for the default.
In some situations the host might have a large amount of routes due to
dynamic routing being used like OSPF or BGP.
In addition fix a couple of loglines which were throwing messages on
DEBUG while WARN and ERROR should be used there.

These additional RBD features allow for faster lookups of how much space a RBD
image is using, but with the exclusive locking we prevent two VMs from writing
to the same RBD image at the same time.
These are the default features used by Ceph for any new RBD image.

This adds a new API updateVmwareDc that allows admins to update the
VMware datacenter details of a zone. It also recursively updates
the cluster_details for any username/password updates
as well as updates the url detail in cluster_details table and guid
detail in the host_details table with any newly provided vcenter
domain/ip. The update API assumes that there is only one vCenter per
zone. And, since the username/password for each VMware host could be different
than what gets configured for vcenter at zone level, it does not update the
username/password in host_details.
Previously, one has to manually update the db with any new vcenter details for the zone.

On actual testing, I could see that kvmheartbeat.sh script fails on NFS
server failure and stops the agent only. Any HA VMs could be launched
in different hosts, and recovery of NFS server could lead to a state
where a HA enabled VM runs on two hosts and can potentially cause
disk corruptions. In most cases, VM disk corruption will be worse than
VM downtime. I've kept the sleep interval between check/rounds but
reduced it to 10s. The change in behaviour was introduced in #2722.

- Prevent mount secondary storage on ISO direct downloads on KVM
Since we support only Ubuntu 16.04+ on master/4.12+, we can now use

Windows has support for several paravirt features that it will use when running on Hyper-V, Microsoft's hypervisor. These features are called enlightenments. Many of the features are similar to paravirt functionality that exists with Linux on KVM (virtio, kvmclock, PV EOI, etc.)
Nowadays QEMU/KVM can also enable support for several Hyper-V enlightenments. When enabled, Windows VMs running on KVM will use many of the same paravirt optimizations they would use when running on Hyper-V.
A number of years ago, a PR was introduced that added a good portion of the code to enable this feature set, but it was never completed. This PR enables the existing features. The previous patch set detailed in #1013 also included the tests.
By selecting Windows PV, the enlightenment additions will be applied to the libvirt configuration. This is support on Windows Server 2008 and beyond, so all currently supported versions of Windows Server.
In our testing, we've seen benchmark improvements of around 20-25% running on Centos 7 hosts and it is also supported on Centos/RHEL 6.5 and later. Testing on Ubuntu would be appreciated.
This tries to provide a threshold based fix for #2873 where swappinness of VR is not used until last resort. By limiting swappiness unless actually needed, the VR system degradation can be avoided for most cases. The other change is around not starting baremetal-vr by default on all VRs, according to the spec https://cwiki.apache.org/confluence/display/CLOUDSTACK/Baremetal+Advanced+Networking+Support only vmware VRs need to run it and that too only as the last step of the setup/completion, so we don't need to run it all the time.

[VMware] VM is not accessible after migration across clusters.
Once a VM is successfully started, don't delete the files associated with the unregistered VM, if the files are in a storage that is being used by the new VM.
Attempt to unregister a VM in another DC, only if there is a host associated with a VM.
This closes#556
When a Instance is (attempted to be) started in KVM Host the Agent
should not worry about the allocated memory on this host.
To make a proper judgement we need to take more into account:
- Memory Overcommit ratio
- Host reserved memory
- Host overcommit memory
The Management Server has all the information and the DeploymentPlanner
has to make the decision if a Instance should and can be started on a
Host, not the host itself.

This is a new feature for CS that allows Admin users improved
troubleshooting of network issues in CloudStack hosted networks.
Description: For troubleshooting purposes, CloudStack administrators may wish to execute network utility commands remotely on system VMs, or request system VMs to ping/traceroute/arping to specific addresses over specific interfaces. An API command to provide such functionalities is being developed without altering any existing APIs. The targeted system VMs for this feature are the Virtual Router (VR), Secondary Storage VM (SSVM) and the Console Proxy VM (CPVM).

This introduces a new global setting `vm.configdrive.primarypool.enabled` to toggle creation/hosting of config drive iso files on primary storage, the default will be false causing them to be hosted on secondary storage. The current support is limited from hypervisor resource side and in current implementation limited to `KVM` only. The next big change is that config drive is created at a temporary location by management server and shipped to either KVM or SSVM agent via cmd-answer pattern, the data of which is not logged in logs. This saves us from adding genisoimage dependency on cloudstack-agent pkg.
The APIs to reset ssh public key, password and user-data (via update VM API) requires that VM should be shutdown. Therefore, in the refactoring I removed the case of updation of existing ISO. If there are objections I'll re-put the strategy to detach+attach new config iso as a way of updation. In the refactored implementation, the folder name is changed to lower-cased configdrive. And during VM start, migration or shutdown/removal if primary storage is enable for use, the KVM agent will handle cleanup tasks otherwise SSVM agent will handle them.
