Opaque is a GPLv3 licensed secure, super fast oVirt, Red Hat Enterprise Virtualization (RHEV), and Proxmox VDI client that allows you to connect graphically to all your virtual machines running in the cloud from anywhere in the world.
If Opaque doesn't work for you, please report the problem through the “Send email" button in Google Play before writing a review.
(1) On most current devices, playing sound and video exceeds the CPU processing power and causes jittery sound and video playback.
(2) If virtual machines are behind a proxy, then the only way to connect to them with Opaque is by using a .vv file. Connections to VMs behind a proxy will fail due to lack of network connectivity to them.
* System administrators: If you are planning to recommend this app, please ensure you are not using a proxy.
* Users: If you're unsure, please ask your System Administrator!
(3) The oVirt web "User Portal" currently does not allow obtaining .vv files for virtual machines. Therefore, because of the previous issue,, if the VMs are behind a proxy only Administrators can connect to them by obtaining a .vv file through the "Admin portal".
(4) Direct connections (set up through Opaque's UI) to Proxmox VMs are currently not supported at all. To connect to Proxmox VMs, you *have to* use the web interface and obtain a .vv file for your VM. The Chrome browser is known to work well for this purpose with the Proxmox user interface.
Current features include:
- Audio playback
- Supports both Proxmox and oVirt/RHEV virt-viewer/remote-viewer (.vv) files
- SSL encryption for peace of mind
- Commercially signed and self-signed certificates
- SPICE protocol support
- Automatic rotation
- Desktop resizing to match display resolution
- Multi-touch UI with four mouse input modes to choose from
- Mouse scrolling by swiping with two fingers up/down
- Single-handed mode for easy on-the-go operation
- Support for most bluetooth input devices.
- Allocating VMs from a pool
- Clipboard integration
- VNC protocol support

It also uses a number of open-source libraries included in the Gstreamer SDK for Android, as well as libcelt, openssl, libgovirt, jpeg-turbo, and librest.
If bVNC doesn't work for you, please report the problem through the “Send email" button in Google Play before writing a review. See below for setup instructions for Windows, Linux, and Mac OS X.
If you need an RDP application, please search for bVNC's sister project aRDP in Google Play. In addition, a SPICE client named aSPICE is now part of the same project. Finally, if you are an oVirt, RHEV, or Proxmox user, you can check out Opaque VDI on Google Play as well.
bVNC is a secure, open source VNC client. Its features include:

- Right and middle-dragging if you don't lift the first finger that tapped
- Scrolling with a two-finger drag
- Dynamic resolution changes, allowing you to reconfigure your desktop while connected, and control over virtual machines from BIOS to OS
- Full rotation support. Use the central lock rotation on your device to disable rotation
- Multi-language support
- Full mouse support on Android 4.0+
- Full desktop visibility even with soft keyboard extended
- SSH tunneling, AnonTLS and VeNCrypt for secure connections (does not support RealVNC encryption).
- High-grade encryption superior to RDP using SSH and VeNCrypt (x509 certificates and SSL), preventing man-in-the-middle attacks

- Supports Mac OS X built-in remote desktop server (ARD) and Mac OS X authentication with user name
- Does NOT support RealVNC encryption (use VNC over SSH or VeNCrypt instead)
- Stowable on-screen Ctrl/Alt/Tab and arrow keys
- Right-click with Back button
- Use D-pad for arrows, rotate D-pad
- Minimum zoom fits screen, and snaps to 1:1 while zooming
