first of all: i (still) love VirtualBox. The ability to migrate VMs between Windows and Linux servers is really cool, and it is still free to use.

NO other Virtualization software can do that! 🙂

and that is exactly my point:

Simon Coter (Director of Product Management since at least 2 years) PLEASE FOCUS ESPECIALLY ON:

… it is THE factor that makes VirtualBox THE STORNGEST competitor of VMWare and POSITIVELY STANDS APART from Hyper-V (i tried to migrate between VirtualBox VMs and Hyper-V, it is catastrophic X-D) and also KVM (Linux Only, i know VirtualBox uses KVM?)

don’t clutter the project with useless features

Because NOBODY will use a fancy Virtualization software that can make cappuccinos with fancy toppings (the build-in screen recording is probably not a good idea, you can install one inside the guest if you want, but i would not assume that ALL users want this feature and make code base unecessary big) if it is UNSTABLE and HARD to keep running/updated.

clean „round“ code is top priority – it needs to be a methamatically profen piece of perfect (or almost perfect) and secure.

feature suggest: vm repository

what is one of the strengths of docker/containers?

there is a free repositories to download, build upon, commit/upload vms!

now with VirtualBox some people (including myself) tried to implement something like this and it probably comes with all kinds of issues on the licensing side, but why not make it like this:

https://oracle.com/virtualization/virtualbox/vms/free -> here is the free repository with free (no costs) vms of all kinds of open source ready to go vms you can download and run

https://oracle.com/virtualization/virtualbox/vms/nonfree -> here is the nonfree repository with commercial (closed source and licensing costs involved) „webshop“ if you want to download ready to go windows server 2019 + (some fancy corporate enhancing software pre installed)

successful in production use:

I have a old Windows Server 2012 R2 still running 5.1.18.

Just a few weeks ago i successfully migrated a VM of this Windows Server 2012 R2 to CentOS 7 (almost latest kernel) and it runs SMOOTH and RELIABLE.

Why am i still using this old version?

I made VERY BAD experiences with UPGRADES and also with VirtualBox upgrades on mission-critical in-production systems (yes i test out upgrades on a backup-server, before i do upgrades on the real server)

I am happy it works as rock solid as it does right now and i intend to keep it that way – may the version be updated as the dinosaurs.

Also Guest Additions DOES NOT EASILY UPDATE with e.g. RedHat/CentOS „yum update“ or Debian/Ubuntu’s „apt update“

no: you will have to find a working version every time you upgrade your linux guest and recompile the modules – or leave your guests without updates.

(or… scroll down for a solution)

  • 5.1.18 grafix driver (?) failed to compile
  • 5.2.22 grafix driver (?) failed to compile
  • 5.2.23 compiles fine, but still „kernel panic“ „intramfs unpacking failed“ „no cpio magic“

… virtualbox graka driver fails to load, then causes kernel panic on reboot.

maybe VBox Additions 5.2.23 is „generally“ incompatible with VirtualBox 5.1.18

version 5.2.23 compiles fine with CentOS7 default kernel… but still kernel panic on reboot.

i am now going for the latest kernel, wish me luck.

also RedHat screwed up? maybe Oracle should worker closer with RedHat?

PS: no offense – but marketing wise maybe more people would watch the interview if it was hosted by an hot woman X-D

23 views in 6 months is… well something X-D

UPDATE: PROBLEM SOLVED! RELIEF!

compiling the latest kernel to date (4.20.2) like so: -> https://dwaves.org/2017/12/17/linux-centos7-install-mate-and-virtualbox-guest-additions/

hostnamectl
    Virtualization: kvm
  Operating System: CentOS Linux 7 (Core)
       CPE OS Name: cpe:/o:centos:centos:7
            Kernel: Linux 4.20.2 <- yeah suck this MICRO BITCHES! X-D
      Architecture: x86-64

… also compiled all available modules for the virtualbox „hardware“ and now it is

RUNNING SUPER SMOOTH! 🙂
THANKS AND GOOD JOB ALL INVOLVED!
