Virtualbox Support 8 NICs for VM Guest

Virtualbox supports up to eight network cards. If you look into the *.vbox you will see that there are already preconfigured but disabled. Unfortunately inside the VBox GUI we could only configure up to four. I will show how to get and configure the other.
You have to use VBoxManage to get the other network cards. After the option will always be the NIC Number count one to eight. Here I will use five and the name of the machine that will be configured is “SFS1”.

Set Mode and enable NIC

When a Mode is set the NIC will be enabled.

C:\Program Files\Oracle VM VirtualBox>VBoxManage.exe
  1. Set NIC five to Host-Only Mode and User vboxnet0 (Initially existing Host-Only Net)
    VBoxManage modifyvm SFS1 --nic5 hostonly
    VBoxManage modifyvm SFS1 --hostonlyadapter5 "vboxnet0"
     
  2. Set NIC five to Bridge "Intel(R) 82567LM Gigabit Network Connection"
    VBoxManage modifyvm SFS1 --nic5 bridged
    VBoxManage modifyvm SFS1 --bridgeadapter5 "Intel(R) 82567LM Gigabit Network Connection"
     
  3. Set NIC to NAT Mode
    VBoxManage modifyvm SFS1 --nic5 nat
     
  4. Use the internal VM net “test01”
    VBoxManage modifyvm SFS1 --nic5 intnet
    VBoxManage modifyvm SFS1 --intnet5 "test01"

Configuring NIC

  • To use VLAN and some other things in VMs the Promiscuous mode have to be enabled
    VBoxManage modifyvm SFS1 --nicpromisc5 allow-all
     
  • Use other hardware type (Intel Pro/1000 MT Server)
    VBoxManage modifyvm SFS1 --nictype5 82545EM
     
  • Dis/connect cable
    VBoxManage modifyvm SFS1 --cableconnected5 off 
    VBoxManage modifyvm SFS1 --cableconnected5 on

Activate Windows Server 2008 R2 Enterprise without Internet Connection



Recently, I faced a situation in which I had to activate Windows Server 2008 R2 Enterprise which didn’t have internet connection. In the earlier days of Windows 2003 there was a Phone Activation option within the wizard. However, in the current edition Windows 2008 onwards the option doesn’t exist.
I am going to show you the steps involved in quickly activated Windows Server 2008 onwards over the Phone using the following command line parameters:
  • Start –> Run –> Command Prompt right click and “Run as a administrator”
  • Type the following command to retrieve the Product Installation id slmgr.vbs /dti (A pop-up windows will appear with a long string of digits)
  • Call the Microsoft activation centers as per your locations from this Microsoft Activation Centers link
    • I used the India number 1800 11 11 00 or 1800 102 1100
  • Provide the Installation ID to the customer care representative and they will provide a Confirmation Number (A long sting of numbers)
  • Type slmgr.vbs /atp (without <>) at the command prompt and you will receive a pop-up that your Windows have been activated successfully
  • To confirm your activation type the following command slmgr.vbs /dli
Go to your Server Manager and you will be able to see the Windows Server 2008 R2 activated

Extending Grace Period on Win2008 R2

Most of the content I use for webcasts and live events have virtual machines that have been created either by someone on my team or by someone at Microsoft corporate.  The virtual machines are not created with trial versions of the operating system but with fully licensed product.  For obvious reasons they are not activated, so when I first boot up I usually get a message saying the machine has to be activated within a few days.  Sometimes though, the machines have past the activation grace period and will not log on unless they are activated NOW!!  This can be somewhat annoying because most of the time I only need the machines for a demonstration the following week, maybe for the next month or so, and I don’t want to use one of my product keys for such a short term machine life.  So what can I do?  
The first thing I do with machines that are requiring immediate activation is simply turn them off.  I then change my host machine date back to a date closer to when the virtual machines were originally created and boot them up one more time.  Now the virtual machine thinks my date is kosher and is within the activation grace period, and lets me logon.  That’s great but the date is wrong and I need to access the internet with the host as well as do my demos, and having a wrong date causes issues.  Never fear, one of the things we can do with Windows Server 2008 and Windows Server 2008 R2 (actually this works with Windows Vista and Windows 7 as well), is re-arm the machine and extend the activation grace period another 60 days.

So How’s This Done?

Simple… all we need to do is run a script in the windows\system32 folder called slmgr.vbs.  Check the steps below:
  1. Bring up a Command Prompt.
  2. Type slmgr.vbs –rearm, and press ENTER.
  3. Restart the computer.
You computer has now extended the evaluation period 60 days!!!  You can re-arm up to 3 times giving you an activation-free trial period of a total of 240 days!!

How Much Time Is Remaining in the Evaluation Period

You can find out by running the same script this time with different switch:
  1. Type slmgr.vbs -dli, and the current status of the evaluation period is displayed.  (the dli switch means – display license information)
If you want to find out what else you can do with the script type slmgr.vbs –? and you’ll get a full list and explanation of all the switches.

Try - Pink

Oh oh

Ever wonder about what he's doing?
How it all turned to lies?
Sometimes I think that it's better to never ask why

Where there is desire
There is gonna be a flame
Where there is a flame
Someone's bound to get burned
But just because it burns
Doesn't mean you're gonna die
You've gotta get up and try, and try, and try
Gotta get up and try, and try, and try
You gotta get up and try, and try, and try

Eh, eh, eh

Funny how the heart can be deceiving
More than just a couple times
Why do we fall in love so easy?
Even when it's not right

Where there is desire
There is gonna be a flame
Where there is a flame
Someone's bound to get burned
But just because it burns
Doesn't mean you're gonna die
You've gotta get up and try, and try, and try
Gotta get up and try, and try, and try
You gotta get up and try, and try, and try

Ever worry that it might be ruined
And does it make you wanna cry?
When you're out there doing what you're doing
Are you just getting by?
Tell me are you just getting by, by, by?

Where there is desire
There is gonna be a flame
Where there is a flame
Someone's bound to get burned
But just because it burns
Doesn't mean you're gonna die
You've gotta get up and try, and try, and try
Gotta get up and try, and try, and try
You gotta get up and try, and try, and try
Gotta get up and try, and try, and try
Gotta get up and try, and try, and try
You gotta get up and try, and try, and try
Gotta get up and try, and try, and try

You gotta get up and try, and try, and try
Gotta get up and try, and try, and try...

Memory Kill - Franco Reyes

I'm here
Watch me on display
I'm soul scratched severed inlay
I fear
Wonder if you'd say
Go get going ok ok ok.....?

Adhere to whatever you may
I'm tongue tied twisted hearsay
It's a severe paralysis
Wallowing insane
Hopeless hoping in vain!

Here's a letter to your pride
Our souls and hearts divide
How can this be?
We're beckoned to a lie
Leave uncompromised
How can this be?
Kill that memory

Cold and pale black memory
Of you and me standing still
Kill kill kill

Here's a letter to your pride
Our souls and hearts divide
How can this be?
We're flailing to decide
Desperate to deny
How can this be?
Kill that memory
Kill kill
