VirtualBox : 101 way

As new player in virtualization field VirtualBox already reach version 1.5.2 .

What VirtualBox have done so far?

Is it good as vmware or Virtual PC?

Dunno, by seeing its implementation You can judge :-)

Googling and forum searching, I found :

  1. Create and Manage Virtual Machines Using VirtualBox, VirtualBox is a general-purpose full virtualizer for x86 hardware. Targeted at server, desktop and embedded use, it is now the only professional-quality virtualization solution that is also Open Source Software.
  2. Installing VirtualBox On Ubuntu, this tutorial shows how you can install InnoTek’s VirtualBox on a Ubuntu desktop. With VirtualBox you can create and run guest operating systems ("virtual machines") such as Linux and Windows under a host operating system.
  3. How to install Ubuntu Studio in Windows using VirtualBox – a complete walkthrough, This tutorial will take you every single step of the way through installing Ubuntu Studio using VirtualBox for Windows. In other words, even your parents should be able to follow along.
  4. VirtualBox On FC6 / CentOS 4 / OpenSuSE 10.2,  
  5. Minimal VirtualBox VRDP Setup – a quick guide, VRDP lets you run a headless server and access the VMs via RDP.
  6. Set up a DOS VM with CDROM & network card & browser. Play DOS in VM.
  7. CloneVDI Tool, a small GUI programm to help cloning the installed VDIs. 
  8. Making VirtualBox public, forward port for public. 
  9. NATing with VirtaulBox and NetworkManager,

Do you build your server with virtualbox, email server  or perhaps dns server?

GNS3 0.3 available

We are proud to announce the version 0.3 of GNS3, this version is considered as a beta.

A lot of new features and bug-fixes are available, the most important are:

– Support of Ethernet, ATM and Frame-Relay switches
– Included hub (Bridge of Dynamips) and cloud (external connections) devices
– Added the Dynagen console (nearly all commands supported)
– New GUI settings
– Improved node configurator
– Load and save in Dynagen INI-like configuration files
– Multi-language support (howto for translators soon)

A documentation has been written and is available in the documentation section on the website

Note: the official name of the project is now GNS3 (not gns-3 nor GNS-3)

Thank you for reporting bugs with details

GNS3 Staff

Great progress by GNS3 team.

Dynagen Version 0.10.1 released to fix NM-16ESW bug and Tutorial updates

From Greg blog :

Continuing my quest to avoid a 1.0 release at all costs, here is version 0.10.0. The most important things in this release are support for 1700 platform emulation and WIC modules Chris added in 0.8.0-RC1. The tutorial has gotten a general update, along with documentation for using the new WIC modules. It also now includes a section with an up-to-date hardware reference that details all the models emulated by Dynamips, which adapters are supported and in which slots. Questions regarding these issues are (understandably) common on the forums.

Version 0.10.0:
* Support for the 1700 platform new to Dynamips 0.8.0-RC1. See the tutorial for supported platforms and modules.
* Support for WIC-1T, WIC-2T, and WIC-1ENET. See the tutorial for supported router platforms and usage.
* Support for NM-CIDS and NM-NAM. Note these are just "stubs" (at least as of this version of Dynamips). You can connect to them using "IDS-Sensorx/0 = …" or "Analysis-Modulex/0 = …" but they don’t actually do anything. See the tutorial for platform support.
* FS#154 – added "confreg" command to set the configuration register of router(s) from Dynagen. e.g. "confreg r1 0x2142" followed by "reload r1". Note changes to the config register will not be displayed in a "show ver" until the router is reloaded.
* FS#182 – Second port of PA-C7200-IO-2FE was not usable
* FS#177 – crash on malformed interface entry in net file
* Dynagen now automatically picks a PA-2FE-TX rather than a PA-FE-TX when referencing a FastEthernet on ports 1-6 on a 7200. You can override this to mimic the old behavior with "slotx = PA-FE-TX".
* the vbs file that launches SecureCRT sessions was missing from the Windows installer package
* Changed the state shown with the "list" command for virtual switches from "n/a" to "always on" to avoid confusion.
* Added an up-to-date list of hardware emulated by Dynamips to the tutorial. Thanks to ggee for performing the initial documentation in this post:

* Accidentally only gave the NM-16ESW 15 interfaces.

Dynamips 0.2.8-RC1 release – Introduction of Cisco 1700 platform and WICs

From Cris blog :

Hello all,

The 0.2.8-RC1 release is available. It requires a Dynagen upgrade since the hypervisor control protocol has been modified. The new Dynagen release will be published by Greg soon.

New features:

  • Support of the Cisco 1700 platforms, with WIC-1T, WIC-2T and WIC-1ENET cards (as for the 2600, the images need to be uncompressed before use).
  • Support of WIC-1T and WIC-2T for the 2600 (2 WIC slots), 2691, 3725 and 3745 (3 WIC slots) platforms.
  • Support of NM-NAM and NM-CIDS interfaces BUT this not means that you can use them out of the box. It means that you can connect your virtual routers to a VMWare, QEMU, … virtual PC running the NM-CIDS/NM-NAM code. I don’t provide a method to do this, but you can take inspiration here: If someone wants to document how to setup this, he/she is welcome.
  • Plugin system (not documented yet) that allows to dynamically load new platforms. It is mainly for coding tests (it avoids to modify the dynamips core with temporary code).

Optimizations / Bug-fixes:

  • New generic card framework to reduce the code specific to each platform (it is transparent to users, and was required for WIC support) ;
  • Fixed JIT compiler for PowerPC and MIPS platforms on MacOS X (stack alignment) ;
  • Fixed JIT compiler for PowerPC on 64-bit Linux platform (incorrect “bctr” instruction) ;
  • Added ISL support for NM-1FE-TX card ;
  • Fixed the Serial cards (NM-4T, PA-4T, PA-8T, PA-POS-OC3, WICs) to handle correctly CRC stuff. Now, you can interconnect them to the virtual Frame-relay switches.

Important note: The use of WIC cards is a bit complicated without Dynagen, so I strongly recommend to use it to mask the gory details.

– added a workaround that ttermpro.exe can not send the server data to ttpmacro.exe with DDE transaction.

– Bug fix: did not save/load "LF" to CRReceive entry in teraterm.ini.
– Bug fix: TeraTerm window size could not be changed after the window size is smaller than 120 dot(94 dot on XP LUNA style). This is TeraTerm 2.3 original bug.
– Bug fix: statusbox does not display ‘\n’ as LF when the statusbox is existing yet.
– Bug fix: some macros are not become an error when the parameter filename starts by ‘:’.
