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 but this instruction is obsolete and offers a version of virtualbox 5.0-?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


We teach FreeBSD to look for files by extended attributes

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.
