Dependencies¶

Installation server¶

The VM-Stack package installer has all the necessary logic to guess and install critical packages if they are missing from the system.

The most important package that will be checked is QEMU, which is the low-level tool that allows for virtual machine creation in the user-space. If not detected on a system (that runs either: Ubuntu, Fedora or OpenSUSE), then the qemu and complementary packages will get installed automatically.

Server hardware¶

What is not checked are the system's virtualization capabilities which should be satisfied by the server provider (so for example your organization's Ops team or You).

The server should have a CPU newer than Intel's Sandy Bridge architecture (so any CPU from 2011 onward), at least 4 CPU cores, 4 GB of RAM, and more than 80 GB of free disk space (one VM without configuration will by default create a 20 GB virtual disk image).

Connecting client¶

All Onteon Stack administration in this special case should be done on the "installation server". Normally Onteon Stack installation is in the form of a cluster and it stretches to at least two nodes (Onteon Control Center and Onteon Node Manager) plus the administrator machine (that runs onteon-cli). In this case all components are installed on the server. This means that also the onteon-cli will be installed remotely (if You are installing on non-local machine).

Remote-Viewer (VM GUI)¶

Any graphical desktop client that wishes to connect and interact with virtual machines in a graphic way needs to have the remote-viewer tool installed.

On Ubuntu the remote-viewer executable is a part of the virt-viewer package. See the Ubuntu's help on remote-viewer.
