Hypervisor in a Hypervisor. Yes you can, but not with Xen.

Google Query: Install Xen on VMware

A colleague of mine recently asked me if it was possible to install the Xen Hypervisor on the VMware Hypervisor. The answer, of course is yes you can install it. However, don’t expect to run any virtual machines on the Xen hypervisor instance. The reason this is not possible is that Xen requires Intel-VT or AMD-V hardware assisted virtualization to function.

This functionality is reserved for the actual Hypervisor that is installed on the physical hardware. The Virtual Machines themselves do not see these advanced processor features. No Virtualized Intel-VT, no Xen VM’s running.

So, technically you can install Xen. However, you will not be able to run any virtual machines on it once you do. What would be the point? Happy Virtualizing.

How to AirPrint through Windows 7

So iOS 4.2 is finally out enabling Airprint functionality for a select few printers (namely the HP Eprint line). What if you don’t have a new wizbang printer? Early in the beta of iTunes 10.1 you could use Airprint to print to Mac OSX and Windows Shared Printers. Sadly, they took that functionality out in the release.

Here’s how to get it back.

1- Install iTunes 10.1
2- Download (airprint.exe, libairprint.dll, XpdfPrint.dll)
3- Unzip it.
4- Make a folder, “C:\Program Files (x86)\AirPrint\
5- Copy the files to “C:\Program Files (x86)\AirPrint\
6- Run “cmd.exe” as administrator
7- Run the following commands (There should be a space between ‘=’ and ‘”‘)

Windows 64bits:
sc.exe create AirPrint binPath= “C:\Program Files (x86)\AirPrint\airprint.exe -s” depend= “Bonjour Service” start= auto
sc.exe start AirPrint

Windows 32bits:
sc.exe create AirPrint binPath= “C:\Program Files\AirPrint\airprint.exe -s” depend= “Bonjour Service” start= auto
sc.exe start AirPrint

8- Let Windows Firewall allow AirPrint to communicate on the networks (Double click on the airprint.exe)

You can download from the MacRumors Forums where I found this solution.

Happy Printing!

How to get a Microsoft SQL Server 2005 Database Out of Standby/Read-Only Mod

Google Query: SQL Server 2005 Database Standby / Read-Only

Recently, I helped a customer restore a SQL Server 2005 database. The only problem was that the default restore was leaving the database in Standby / Read-only mode. The solution to this problem was really quite simple. After some googling I came across this MSDN Thread.

Basically to restore the database from a backup and put it back into production mode, just run the following SQL query:

RESTORE DATABASE <database_name> FROM <full_backup> WITH RECOVERY;

Happy Database Restoring!

Pictures Missing from iPhoto Library

Google Query: iphoto not showing all pics in the library

My wife loves her MAC. Ever since we switched her to it from a PC, I have not had to do tech support at home. However, sometimes even MACs do strange things. My wife noticed that not all of the pictures were showing up in her iPhoto Library. I took a look and was about to resort to the daily backup that we do on her MAC.

However, Google came to the rescue again. After a quick search, I found the answer on the Apple Forums. Basically, I had to rebuild the iPhoto database by taking these steps:

  • Launch iPhoto with the Command + Option keys depressed.
  • Follow the onscreen instructions to rebuild the iPhoto database and thumbnail cache.

That’s it! After about 10 Minutes the iPhoto database had been rebuilt and the pictures were showing up again. Happy Photo browsing!

A utility to get past the “Error Deleting File or Folder” error.

Have you ever run into any of the following when trying to delete a file?

  • Cannot delete file: Access is denied
  • There has been a sharing violation.
  • The source or destination file may be in use.
  • The file is in use by another program or user.
  • Make sure the disk is not full or write-protected and that the file is not currently in use.

I found a slick utility today that will help you release the locks on a file and solve this problem without having to reboot your PC. It’s called Unlocker.

The instructions on the Unlocker Site are pretty straightforward. Happy File Unlocking!

Upgrading RAM in VMware Player VM

I get a lot of questions on how to upgrade the memory in a VMware Player Virtual Machine (VM). So, I figured I would post it so everyone can see. It’s actually quite easy. Just follow these steps:

  • Look for a *.vmx file in the directory that your VM is stored in.
  • Open up this file in notepad or your favorite text editor (make sure the VM is shut down).
  • Look for a line that looks like this: memsize = “256″
  • Change the number to equal the amount of RAM that you want in your VM
  • Start the VM and enjoy your new RAM

So there you have it. Just edit a simple text file and your VM has more RAM. Happy Virtualizing!

Free Crossover on Ubuntu FTW!

I had been contemplating getting Crossover for a while because it is an “easier to setup” WINE implementation. But, I don’t like paying for stuff when I could do it myself for free. Now I can get the best of both worlds! In case you are wondering Crossover lets you run some Windows applications on your Mac or Linux machine without using a virtual machine.

Today and tomorrow only, Codeweavers is offering their products for free! How cool is that? You could run Office with Crossover, but we all know you will be running Team Fortress 2 or World of Warcraft. Happy Gaming!

How to reset the offline folder cache on Windows XP Tip

If any of you have ever worked with offline folders in Windows, you know how frustrating it is when a server changes or is no longer available and Windows still tries to keep the offline folders synchronized. This is not only annoying for one user, but is extremely annoying in a shared computing environment where multiple users log on to the same PC. This is because offline files stores files for every user that logs on and it tries to synchronize every users’ offline files every time.

When offline files become a burden, there is a simple trick to reset the offline file cache on Windows XP (it is not obvious if you have never done it before). The steps are below:

-You must be logged on as a user with Administrator Rights.

-Open up Windows Explorer by pressing “Windows Key + E” (or by using the myriad of other ways to open Windows Explorer).

-Navigate to Tools -> Folder Options

-Go to the Offline Files tab

-Now hold down “CTRL+SHIFT” and left click on the “Delete Files…” option.

-A confirmation message will appear.

-Click “Yes”

-Click “OK” on the Offline Files option window.

-Reboot your computer.

-Now the offline files cache has been reset and you can start corrupting it again from scratch! ;)

That’s it! Happy file caching!
