* server: fix resource count of primary storage if some volumes are Expunged but not removed
Steps to reproduce the issue
(1) create a vm and stop it. check resource count of primary storage
(2) download volume. resource count of primary storage is not changed.
(3) expunge the vm, the volume will be Expunged state as there is a volume snapshot on secondary storage. The resource count of primary storage decreased.
(4) update resource count of the account (or domain), the resource count of primary storage is reset to the value in step (2).

After a local template is uploaded via browser, the generated usage event with type = "TEMPLATE.CREATE" is persisted with the data store ID instead of the zone ID on the zone_id column. The fix will refactor the upload monitor logic, as after the upload completes, it sets the datastore ID on the zone ID column for the created "TEMPLATE.CREATE" usage event. This refactor will query the DB for the data store and will set its associated zone ID in the usage field.
The fix produces the same behaviour as when registering a template from URL.
FIx is also for uploading VOLUME from local/via browser.
When we restart the VPC after destroying the master VR, the backup VR

The VM ingestion feature allows CloudStack to discover, on-board, import existing VMs in an infra. The feature currently works only for VMware, with a hypervisor agnostic framework which may be extended for KVM and XenServer in future.
Associating static NAT on IP to VM fails even though the IP is not allocated.
When we try enable static NAT on second IP address to the same VM, the operation fails but the IP address is still allocated in the db and it can't be used to enable static NAT on different VM.
Steps to reproduce the issue:
(1) create a vpc (vpc-001) and a vpc tier (vpc-001-001)
(2) create a vm (vm-001-001) in vpc-001-001
(3) acquire a public ip (ip-1) and enable static nat to vm-001-001,
operation succeeds.
(4) acquire a public ip (ip-2) and enable static nat to vm-001-001,
operation fails but the ip is still assigned to vpc tier vpc-001-001.
Note down the ip address and the id of it.
(5) create another vpc tier vpc-001-002, and vm (vm-001-002) in the tier
(6) enabled ip-2 static nat to vm-001-002, operation should succeed

When a template is registered, code stores md5sum of the downloaded file in the vm_template table. However, this downloaded file could be deleted after template installation if it is not an actual (.qcow2, .ova, etc.) file. When the user copies a template using copyTemplate API, the actual template file will be copied across the image stores. Matching checksum for the copied templated file and the stored value from the vm_template table will result in a mismatch.
Changes will set an empty checksum value for the copied template while passing to download service which allows skipping wrong checksum check for the copied while install.
However, this results in a change in checksum value for concerned template entry in vm_template table post template install.

(2) create a vm with the offering
(3) update vm with displayvm=false, returns an error

When start a vm or migrate a vm (away from a host in host maintenance), cloudstack will check capacity of all hosts and choose one. If there are hundreds of hosts on the platform, it will take some seconds. When cloudstack choose a host and start/migrate vm to it, the resource consumption of the host might have been changed. This normally happens when we start/migrate multiple vms.
It would be better to double check the host capacity when start vm on a host.
This PR includes the fix for cpucore capacity when start/migrate a vm.
When we calculate a resource consumption of a host, we need to take the vms in following states into calculation: Running, Starting, Stopping, Migrating (to the host), and vms are Migrating from the host. Because, when stop a vm, the resource on host will be released when vm is stopped. When migrate a vm, the resource on destination host will be increased before migration starts, and resource on source host will be decreased after migraiton succeeds.
In cloudstack, there is a task named CapacityChecked which run every 5 minutes (capacity.check.period =300000 ms by default). It recalculates capacity of all hosts. However, it takes only vms in Running and Starting into consideration. We have faced some issues in host maintenance due to it.
Steps to reproduce the issue
(1) migrate N vms from host A to host B, cpu/ram resource increases before the migration.
(2) capacity check recalculate the capacity of hosts. used capacity of Host B will be reset to original value (not including the vms in Migrating).
(3) migrate some more vms from other host to host B, the migrations are allowed by cloudstack (because used capacity is incorrect). If the actual used memory exceed the physical memory on the host, there might be some critical issues (for example, libvirt dies)
Steps to reproduce the issue
(1) create an account (test)
(2) create a vm with the account (test)
(3) login with admin, and upgrade the vm to another offering
(4) the resource count (cpu,memory) of admin increases, not the account (test).

Currently while creating ingress/egress rule for a security group,
we can specify only TCP/UDP/ICMP. Sometimes we need to add rules
for different protocol number or rules for all the above three
mentioned protocols.
In this new feature users can specify the protocol number or select
"ALL" option which will apply rules for TCP/UDP/ICMP
Currently in cloudstack, when we click on "Acquire New Ip", it will
randomly acquire IP from the pool. With this enhancement, it is
possible to select the IP from the drop down IP list of that network.
Same thing applies for a VPC as well.

After commit fbf488497f, admin need to specify an ipv4 or ipv6 addresses when add IP to nic which breaks backward compatibity. If IP is not specified, a IPv4 address should be returned.
KVM is supported on arm64 Linux (https://www.linux-kvm.org/page/Processor_support#ARM:).
For a small (IoT) platform such as the new Raspberry Pi 4 that uses armv8 processor
(cortex-a72) it's possible to run Linux host with `/dev/kvm`
accleration. This adds support for IoT IaaS in CloudStack.
This PR is from a fun weekend project where:
- I set up a Raspberry Pi 4 - 4GB RAM model with 4 CPU cores @ 1.5Ghz, 128GB SD samsung evo plus card
- Installed Ubuntu 19.10 raspi3 base image: http://cdimage.ubuntu.com/releases/19.10/release/ubuntu-19.10-preinstalled-server-arm64+raspi3.img.xz
- Build a custom Linux 5.3 kernel with KVM enabled, deb here: http://dl.rohityadav.cloud/cloudstack-rpi/kernel-19.10/ and install the linux-image and linux-module
- Then install/setup CloudStack on it (fix some issues around jna, by manually installing newer libjna-java to /usr/share/cloudstack-agent/lib)
- Since the host processor is not x86_64, I had to build a new arm64 (or aarch64) systemvmtemplate: http://dl.rohityadav.cloud/cloudstack-rpi/systemvmtemplate/
I could finally get a 4.13 CloudStack + Adv zone/networking to run on it
and deployed a KVM based Ubuntu 19.10 environment and NFS storage.
Deployed a test vm with isolated network, VR works as expected. Console
proxy works as well, for this tested against arm64 openstack Debian 9/10
templates.
I raised the issue of enabling KVM in upstream Ubuntu arm64 build: https://bugs.launchpad.net/ubuntu/+source/linux-raspi2/+bug/1783961
Ubuntu kernel team has come back and future arm64 releases may have
KVM enabled by default.
Limitation: on my aarch64 env, it did not support IDE, therefore all
default bus type for volumes are SCSI by default. With VIRTIO it fails
sometimes.

When a network IP range is removed, the "vlan" stays mapped on pod_vlan_map; therefore, the method that lists the VLANs by pod id will return null VLANS.

Problem: In Vmware, appliances that have options that are required to be answered before deployments are configurable through vSphere vCenter user interface but it is not possible from the CloudStack user interface.
Root cause: CloudStack does not handle vApp configuration options during deployments if the appliance contains configurable options. These configurations are mandatory for VM deployment from the appliance on Vmware vSphere vCenter. As shown in the image below, Vmware detects there are mandatory configurations that the administrator must set before deploy the VM from the appliance (in red on the image below):
Solution:
On template registration, after it is downloaded to secondary storage, the OVF file is examined and OVF properties are extracted from the file when available.
OVF properties extracted from templates after being downloaded to secondary storage are stored on the new table 'template_ovf_properties'.
A new optional section is added to the VM deployment wizard in the UI:
If the selected template does not contain OVF properties, then the optional section is not displayed on the wizard.
If the selected template contains OVF properties, then the optional new section is displayed. Each OVF property is displayed and the user must complete every property before proceeding to the next section.
If any configuration property is empty, then a dialog is displayed indicating that there are empty properties which must be set before proceeding
image
The specific OVF properties set on deployment are stored on the 'user_vm_details' table with the prefix: 'ovfproperties-'.
The VM is configured with the vApp configuration section containing the values that the user provided on the wizard.
This reverts commit 7a27e35a61.
We're near 4.13 RC1, we've low confidence if the changes from #3152
would cause other regressions so reverting this. The author may send a
PR again towards 4.14.
Regressions found are all related to template and iso registration and
upload.

- This allows getUploadParamsForIso for all user role types, also fixes
authorised field for getUploadParamsForTemplate API.

Retrieval of an image store using ImageStoreProviderManager has been refactored by introducing three different methods,
DataStore getRandomImageStore(List<DataStore> imageStores);
To get an image store for reading purpose. Threshold capacity check will not be used here.
DataStore getImageStoreWithFreeCapacity(List<DataStore> imageStores);
To get an image store for reading purpose. Threshold capacity check will be used here and the store with max free space will be returned. If no store with filled storage less than the threshold is found, the NULL value will be returned.
List<DataStore> listImageStoresWithFreeCapacity(List<DataStore> imageStores);
To get a list of image stores for writing purpose which fulfills threshold capacity check.
Correspondingly DataStoreManager methods have been refactored to return similar values for a given zone.
Fixes#3287 - NULL value will be returned when secondary storage is needed for writing but there is not store with free space.
Fixes#3041 - Rather than returning random secondary storage for writing, storage with max. free space will be returned.

Currently when refreshing disk usage stats all kvm agents are asked to collect stats for all volumes. In setups with multiple kvm hosts where managed storage is used, not all volumes are attached to all kvm hosts, this results in a large number of warnings in the kvm agent logs.

When adding iprange for VLANs there are 3 cases -
VLAN under consideration has a tag (like 101)
VLAN under consideration has a tag but as a range (like 101-124)
VLAN is untagged (i.e. id is "untagged")
Before adding iprange we have to check for possible overlaps and throw exception. This needs to be done as follows -
If VLAN Tag ID is numeric or a range we need to call UriUtils.checkVlanUriOverlapmethod which internally tries to expand the range as verifies if there are overlaps. If URI overlaps (i.e. there are overlapping VLAN tags) we then need to verify if the iprange being added overlaps with previously added ranges.
If there are no overlapping tags we simply need to test for public networks being present in the VLAN.
A Regression was introduced in 41fdb88#diff-6e2b61984e8fa2823bb47da3caafa4eeR3174 which caused comparing 'untagged' string as a numeric VLAN Tag range and and attempted expanding it to test overlap in UriUtils.checkVlanUriOverlap.
To fix the bug in the issue, we need to handle the untagged case separately as it's non-numeric tag in code. For untagged VLANs and overlapping VLAN URIs we need to check for ipranges and gateways which happens naturally after this change. For tagged VLANs with non-overlapping URIs we need to check if there is a public network.

Currently an admin can choose which host a VM is to be started on.
They should be able to 'override' the allocation algorthm to a greater
or lesser extent at will, and be able to choose the pod, cluster or host
that they wish a new VM to be deployed in.
DeployVirtualMachine API has been extended with additional, optional
parameters podid and clusterid that will be passed to and used in the
deployment planner, when selecting a viable host. If the user supplies
a pod, a suitable host in the given pod will be selected. If the user
supplies a cluster, a suitable host in the given cluster will be selected.
Based on the parameter supplied and on passing validation, the VM will
then be deployed on the selected host, cluster or pod.
