Secure Virtualization








In the escalating battle against malicious attackers who want to compromise enterprise level systems, you need cost-effective solutions to stop potential threats — both inside and outside the walls of government offices. Red Hat delivers rigorous security controls to prevent unauthorized access to systems and data with Red Hat® Security-Enhanced Linux® (SELinux) and Red Hat sVirt for virtual and cloud environments.

Dear all,

Again an interesting talk. This one will be about DeltaCloud API.

Michal Fojtik will be presenting in Virtualization and Cloud Devroom on  Saturday 2012-02-04

15:00-15:25 Open Clouds with Deltacloud API   (room : Chavane)

Here is the abstract :

Start an instance on an internal cloud, then with the same code start another on EC2 or Rackspace. Deltacloud protects your apps from cloud API changes and incompatibilities, so you can concentrate on managing cloud instances the way you want. Deltacloud API prosper from natural open-source evolution and use community driven API design instead of vendor enforced one.

Dear *, I am going to prepare a presentation and a demo about Linux Container – LXC – on Red Hat/Fedora for Loadays and other events.
Ok, I still have some little issues but I think the bigger part is done.

Let me know if that subject could be interesting for you.
Rem : I did not submitted that subject to the Loadays team yet.

User Mode Linux is another mean to run independent, safe and secure Virtual Linux distributions, versions and processes on your main Linux system.
Unfortunately, often unknown by System Administrators.

Ok, it use paravirtualized technique but if you are using Linux Virtual machines on Linux Physical Machine it is most of the time responding to your basic needs – e.g. web servers, and so on -.

You will be able to use it on Fedora 10 with the following package : uml_utilities.i386 0:20070815-5.fc10
Otherwise you can download it on the UML website

It contains uml_net, uml_mconsole, uml_switch, tunctl, and a number of other useful utilities in order to use the user-mode linux kernel.

You will find a great article at the following URL :

Obviously, It exists also other techniques, methods in order to run VM – virtual machines – on Linux and VmWare is probably one of the most known.- Marketing have done its job, you see what I mean 😉 –

However, it is not always the right answer to your needs and requirements.
Here is a list of Open source Virtualized project as well as their associated types and licences:

Emulation type :
Bochs – Licence -> LGPL –
QEMU – Licence -> LGPL/GPL –

Paravirtualization type :
UML – Licence -> GPL –

Paravirtualization and Full virtualization type – with v-processors (Intel, Amd) – :
Xen – Licence -> GPL – (own by Citrix now)

Operating system-level virtualization type :
Linux-VServer – Licence -> GPL –
OpenVZ – Licence -> GPL –

Full Virtualization
KVM – Licence -> GPL (supported by Red Hat)
Virtualbox – Licence -> GPL

Proprietary Solution & Full Virtualization :
VmWare – Licence -> Proprietary Solution –

Now, it is up to you to choose the application which best fit your strategy, your requirements, your budgets and your needs.

BTW, Thanks to Eddy to have shown me what I did not see. 😉
