Windows 7 64-bit: Full-screen 32-bit DOS program

One of the old MS-DOS programs that I need to use won't run on a 64-bit operating system, and I run Windows 7 64-bit as my desktop.  I tried changing all the compatibility settings, but nothing would work.  The next logical step (in my mind) was to run it in one of our Windows XP virtual machines.  Unfortunately, remote desktop (aka terminal services) doesn't have the capability to load full-screen MS-DOS fonts due to performance issues, and this causes the following error message:

The video device failed to initialize for fullscreen mode. Choose 'Close' to terminate the application.

So using remote desktop to access a 32-bit virtual machine was out of the question.  The next idea that came to mind was using a feature of Windows 7 called Windows XP Mode.  This simply creates a virtual machine on your Windows 7 desktop that you can use to run legacy applications.  It can be downloaded here.  Make sure you remember the password you create, because even if you check the box for automatic log in, you'll need it in a few steps.

Once I got this up and running (it's pretty buggy), I copied my MS-DOS program onto the virtual XP machine and tried to run it.  Guess what? Same error!

The video device failed to initialize for fullscreen mode. Choose 'Close' to terminate the application.

This seemed bizarre to me, so I changed the only readily-available setting for the VM:  I clicked on Tools --> Disable Integration Features.  After doing this, the program ran perfectly!

What a pain, just for some old DOS program, huh?

Integrating VMware VDR with Backup Exec

VMware VDR is working properly for our on-site backups and data recovery (others have had a lot of problems with it, but it works for us), and I needed to figure out a simple way to get our backups off disks and onto tape for off-site storage.  Although is possible to replicate the VDR backups for off-site storage if you are using a SAN with replication technology, I can’t allocate enough space on our SAN right now to store/replicate the backups, so that is not an option.

Our VDR appliance is sending backups to a simple NTFS share on our backup server.  The backup server has Symantec Backup Exec (2010) and an attached LTO4 tape library that I will use copy the VDR backups to tape.  The task seems pretty straightforward, except for the fact that the VDR appliance needs to be powered off in order to ensure valid backups.  You don't want VDR to start an integrity check or backup job in the middle of your copy to tape.

The first thing I thought of was to configure a scheduled task in vCenter to shut down the VDR appliance in the morning and turn it back on at night (presumably after the tape backup has completed).  This would technically work, but I don't like having VDR powered off all day.  It's a pain to power it on each time you want to check settings or to let the integrity check run. 

The solution I came up with was to add a pre-command and a post-command to the Backup Exec job to power off and power on (respectively) the VDR appliance.  The first thing I had to do was install the vSphere CLI on the backup server (I installed it to C:\vCLI, for ease of access).  Once this is installed, you'll need to create batch files for the pre/post commands (I'm not sure why, but it doesn't work if you put the commands directly into Backup Exec), then add the proper pre/post commands into Backup Exec after verifying that they do what you want (shut down and restart the VDR appliance):

1. Install the vSphere CLI on the server that runs Backup Exec.
2. Run the following command from the vSphere CLI:
• C:\vCLI\bin>vmware-cmd.pl -H ESXHOST -U USERNAME -l
3. Where ESXHOST is the ESX/ESXi host that the VDR appliance is running on and USERNAME is the account that has access to this ESX server (usually "root").
4. The previous command will give you a list of vmx files.  Copy the line that lists the VDR appliance's vmx file.  It will probably look something like this:
• /vmfs/volumes/4bbb70ad-10e222d0-4d79-001018645db2/VDR/VDR.vmx
5. This gives you all the info you need to create your pre/post batch files.  They will be (starting with the pre-command batch file):
• C:\vCLI\bin\vmware-cmd.pl -H ESXHOST -U USERNAME -P PASSWORD "VMX-FILE-PATH" stop soft
• C:\vCLI\bin\vmware-cmd.pl -H ESXHOST -U USERNAME -P PASSWORD "VMX-FILE-PATH" start
6. Test these batch files before starting your backup job, and make sure that they work properly!  The first one should gracefully shut down your VDR before the backup job begins, and the second one will power it back on when the backup completes.
7. Add the batch files you created to the pre/post command fields inside your Backup Exec job.
8. Now theVDR appliance will only be offline during the actual backup process!
