Client Internet in an isolated QEMU virtual machine using port tunneling through the SPICE channel

21/11/2018 09:12
The usual approach to connecting a virtual machine to the Internet is similar to connecting any other device to the network and consists of connecting a virtual or forwarding real network interface, as well as setting up and checking network connections, services, routing rules and filtering traffic and so on.

If the virtual machine is a server or is a virtual desktop and is assigned to a specific user, this approach is fully justified, but what if the virtual machine is a public virtual desktop and anyone can connect to it for free?

How to cut off the light in a small data center: a cheap emergency deployment method

There is no budget, you need to look for an existing solution. 3r3113.  3r3151. 3r3113.  3r3151. The normal case (this is not counting the appearance of the second input, the transfer of equipment or the appearance of a diesel generator) - deploy the second exactly the same instance in the cloud and switch to it if something suddenly falls. Called Disaster Recovery. Some of them are building a second data center, it is cold and is waiting for the main one to fall...

Hypervisor for Dummies

27/10/2018 17:38
Hello! I decided to share the experience of creating a hypervisor based on Ubuntu server ??? LTS and a free virtual machine virtualbox 5.2 with a web-based management interface for both the server itself (webmin) and virtual machines (phpvirtualbox). On the net you can find a crooked instruction to raise the above on ubuntu server 16.0? but this instruction is obsolete and offers a version of virtualbox 5.0-? despite the fact that at ??? version 5.2 had already taken root in the official repositories. Here we fix it all. This instruction applies to ubuntu server 14.0? and to ???. On more ...

ZFS and disk access speed in hypervisors

16/09/2018 19:15 This article publishes the results of measurements of the speed of access to the file system inside the hypervisor in various versions of the ZFS installation. To all who are interested I ask under the cut, I warn about the presence of a large number of images under the spoilers (optimized).

kvaps ), However I could not find comparative performance tests of virtualized machines on the Internet (maybe badly looked for?). So I decided to build a test platform for my comparative study.
