Virtual desktops on Linux?

Question

linux

Hello!
The following task appeared:
to deploy a system on one powerful server with the ability for users to connect to this system, as to a desktop. Each user should be assigned a certain strictly defined configuration (for example, 1 core, 2GB of RAM, etc.). Everything should be as transparent as possible for the end user (connected, worked, disconnected).
The number of users is unknown (i.e. at one moment there may be 1, or there may be 100). There should be something like a dynamically expanding pool of virtual machines that users connect to.
The environment is the same for everyone, users do not have to store anything on the destination VM.
Googling on this has shown that Microsoft hasVirtual Desktop Infrastructure (VDI) , while VMware has View ( good description of what I want to get ).
Microsoft's solution is not suitable - the server, VM and clients will be on Linux.
The VMware solution is conditionally suitable, but it is unlikely to be used in our project due to the proprietary nature of the product.
Question: are there any means how to deploy the same on Linux (RedHat)? KVM, Xen, VirtualBox and so on, any ideas are of interest.

Answer 1

And why such a strange statement of the problem?
Why can't you use it as a terminal server?
Well, profiles for users to create temporary.

Answer 2

There is xrdp. Not so long ago I had fun about this and put such a server based on (x)ubuntu. Access outside - rdp with login / password, which is very convenient for Windows users - they do not need any new clients, but it raises a VNC session inside. The scheme is quite working. If there are questions, I can help.

Xen has XenDesktop and XCP ;) You can try to cross.
In general, a pool of cars with a lot of storage, inside it is XCP/Eucalyptus/RHEV/whatever. Access to machines - through X2Go (inside the locale it will work much faster than any other more or less open solution). 1 virtual machine = 1 user. To teach users to start and stop virtual machines through the control panel (or, if resources allow, not to teach anything). Something like this is most like what you need.
