Hypervisor for Dummies

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 but this instruction is obsolete and offers a version of virtualbox 5.0-?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 ...

How to patch find under FreeBSD?

 
3r3-31.

We teach FreeBSD to look for files by extended attributes

3r3394.  
Summary: The FreeBSD OS has a file system-level control mechanism for extended file attributes (extattr). Using the standard commands setextattr, getextattr and rmextattr you can create, read and delete comments, keywords and other file metadata. But you cannot search for files by extended attributes. In addition, extended attributes are lost when copying a file. In two articles, I will offer my patches for the find and cp commands that eliminate these shortcomings. However, I am not a professional programmer ...[/h]

Expand the LINSTOR store for Proxmox

Expand the LINSTOR store for Proxmox
 
LINBIT recently released their new solution for orchestrating and managing multiple DRBD arrays.
 
For example, you can have several nodes and each will have its own LVM or ZFS pool in which LINSTOR will automatically create new volumes and replicate them between nodes using the DRBD protocol.
 
LINSTOR supports thin-provisioning, snapshots and many other interesting things.
 
This solution is well suited for virtual machines and containers.

I believe that you already have a Proxmox cluster, I have three nodes pve1 , pve2 and pve3 ...

First impressions of the transition from Ubuntu ??? LTS to Ubuntu ??? LTS

As you know, the main visual change in the release of 18 is the rejection of Unity and the transition to Gnome 3. Here I want to share my impressions of the transition from 16 to 18
 
 

First about the good


 
Release 18 brought us a new Linux kernel (???) with patches from Meltdown and Specter, which are included by default and, according to the predictions of experts, should greatly degrade the performance of the computer. However, despite the fact that my processor (Intel Core i5) is on the list of vulnerable ones, which means that the patches for it are included, which is confirmed by the ...[/h]

ToFoIn v 1. Redundancy of gateways and switching between external channels in FreeBSD

Annotation


 
In the last publication, the issue of organizing reservations for local network gateways was considered. As a variant of the solution, a script was proposed, which at that time solved the problem, but had a number of shortcomings. After some time, it was possible to eliminate these shortcomings, partially to rewrite the code and to get something acceptable at the output. Now we can say that the scripts are sufficiently tested to be called stable. To simplify the understanding of the entire system, the main points for setting up secondary services (in terms of the topic of the article) ...[/h]
