Setup

After successfully installing the application, you need to set the connection details up:

• API URL: http://host:port/ovirt-engine/api
• Username: name@domain - e.g. admin@internal
• Password: your password

• Certificate Management: download trusted certificate from the engine or supply your own

You can also set optional settings:

• Poll Events: leave checked if you want events in the main sync

• Connection Notifications: shows notification first time the connection is lost

• Periodic Sync: periodic sync when the device is online

• Sync Interval: interval in minutes

• Max events polled¹: the maximum number of events polled in each main sync or on main events tab

• Max events stored¹: the maximum number of events stored on a device

• Events Search Query: poll events for the search query. E.g. severity > warning, see API 3.0 Documentation for syntax.

• Max VMs polled: maximum number of VMs polled.

• VMs Search Query: poll VMs for the search query. E.g. name = "production", see API 3.0 Documentation for syntax.

[1]: max polled = max stored before moVirt 1.8

Remote Consoles

Follow these steps to connect to remote console:

VNC

• Install bVNC from Google Play
• Start up VM and refresh it in moVirt
• Click Vnc Console button in VM's menu

SPICE

• Install aSPICE from Google Play
• Start up VM and refresh it in moVirt
• Click Spice Console button in VM's menu

Augmented Reality

You can use your smartphone/tablet camera to help managing your servers. Follow these steps to access augmented reality:

1. Generate Data Matrix codes for each host you running (this step will be simplified in future).

• Open http://host:port/ovirt-engine/api/hosts in your browser and find host ID.
  
• Make data matrix codes with any online generator containing these IDs as a text (one code for each ID).
  

2. Print and stick codes to physical servers.
3. Open Scan Codes option in moVirt and you are ready.
   

Dashboard

Consists of

• Physical Overview¹

  • Overview¹: shows state of all entities
  • Most Utilized Hosts¹: hosts sorted by cpu usage
  • Physical Resources: shows utilization of all hosts and storage domains

• Virtual Overview¹

  • Overview¹: shows state of all entities
  • Most Utilized Vms¹: vms sorted by cpu usage
  • Running Vms: shows utilization of running vms and all disks

[1]: only for tablets

Notes

• moVirt uses recently fetched data to compute the dashboard compared to the oVirt's webadmin which uses average over the last 5 minutes.
• Dashboard is affected by the settings, i.e. by the queries and by the number of vms/events downloaded

Explanation of Dashboard

Both tablet and phone version include physical resources and running vms utilization.

They will be described bellow.

Physical Resources

Physical CPU

Z% Available od Y%

• Z = average cpu usage of all hosts
• Y = always 100%

X% (Allocated W%)

• X = overcommit; (up vm cores¹) / (all physical cores³)
• W = (all vm cores²) / (all physical cores³)

V% Used

• V = Y - Z

[1]: Allocated cores of running Virtual Machines (with status UP)
[2]: Maximum number of cores that can be allocated to all Virtual Machines
[3]: Physical cores of all Hosts

Physical Memory

Z Available od Y GiB

• Z = available memory of all hosts
• Y = total memory of all hosts

X% (Allocated W%)

• X = overcommit; (all up vm total memory¹) / (all physical memory³)
• W = (all vm total memory²) / (all physical memory³)

V GiB Used

• V = Y - Z

[1]: Total memory of running Virtual Machines (with status UP)
[2]: Total memory of all Virtual Machines
[3]: Total memory of all Hosts

Physical Storage

Z Available od Y GiB

• Z = available space in all active Domains¹
• Y = total space in all active Domains¹

X GiB Used

• X = Y - Z

[1]: applies to Data Storage Domains with status ACTIVE

Running Vms

VMs CPU

Z% Available od Y%

• Z = average cpu usage of all running vms¹
• Y = always 100%

X% Used

• X = Y - Z

[1]: Virtual Machines with status UP

VMs Memory

Z Available od Y GiB

• Z = available memory of all running vms¹
• Y = total memory of all running vms¹

X GiB Used

• X = Y - Z

[1]: Virtual Machines with status UP

VMs Storage

Z Available od Y GiB

• Z = available space of all Disks¹
• Y = total space space of all Disks¹

X GiB Used

• X = Y - Z

[1]: Does not include snapshots
