                          Parallels Has a Command Line Tool Too!

                          When I wrote the head to head review of Parallels and Fusion for InfoWorld, I also did a sidebar on remote control of hypervisors and guests. At the time I wasn't aware that Parallels also has a command line tool called prlctl for managing the hypervisor and controlling guests. A simple "man prlctl" told me all I needed to know and a minute later, I was starting, stopping, and suspending guests from the terminal. The screenshot to the right (click to enlarge) shows it in the process of suspending a Vista operating system guest on my machine. In addition

                          Fusion vs. Parallels: The Horse Race Continues

                          My second review of Fusion and Parallels appeared today in InfoWorld. I reviewed Fusion 1.0 and Parallels 3.0 a little over a year ago. They've both had major upgrades since then, so it was time for another look. The bottom line is that there's not a lot of difference between these two products. They both perform well and do what you'd expect them to. They both have lots of cool features--especially for Windows users on the Mac--the core audience. The differences are minor. While some of those differences might be the reason that you'd prefer one over the other,

                          Reactivating Vista in Parallels 4.0

                          Windows Vista (oops, can I still call it that?) has "Windows Genuine Advantage" and so when it's moved to new hardware have having been installed somewhere else, it needs to be "reactivated." Parallels Desktop was recently updated to version 4.0. This apparently involved some changes to the virtualized hardware presented to the OS since machines created with older versions of Parallels have to be upgraded. You can see where this is going. The conversion process "fails" with a message that something has to be done manually. When you get into the machine, Vista is asking to

                          Parallels and OS X Instability

                          Lately, I've had a very rocky relationship with my Mac Book Pro. One of the things that attracted me to OS X was its stability. Over the past several months (before and after Leopard) my MBP has had trouble with sleeping, waking, and weird, inexplicable freezing. Often when the machine woke up, it would the screen would be black and never come back. The machine would freeze at odd times and nothing would unstick it. I couldn't even log in remotely using SSH, so it was pretty stuck. The final straw was erratic mouse behavior. The mouse seemed sluggish

                          What Should I Buy? Parallels or Fusion?

                          InfoWorld asked me to do a head-to-head review of Parallels and Fusion. That review appeared today. As a frequent user of both virtualization packages, I really enjoyed this review since it gave me an excuse to dig deep on some things and to talk to the product managers for both. One thing is clear: there's some stiff competition between Parallels and VMWare and the users are the winners. These are both great products that perform well. VMWare has a performance advantage--especially when you need multi-core performance. Parallels, I think, has a slight advantage in usability and a pretty big

                          Why Vista?

                          I just put an article up at Between the Lines wondering why anyone would use Vista in a virtual machine if their primary goal is to be able to run Windows applications on their Mac.

                          P2V: How To Make a Physical Linux Box Into a Virtual Machine

                          Over the last four days, I've been exploring how to convert physical Linux boxes into virtual machines. VMWare has a tool for doing P2V conversions, as they're called, but as far as I can tell it only works for Windows physical machines and for converting various flavors of virtual machines into others. I've had a Linux machine that I've used in my CS462 (Large Distributed Systems) class for years. The Linux distro has been updated over the years, but the box is an old 266MHz Pentium with 512Mb of RAM. Overall, it's done surprisingly well--a testament to the small

                          Parallels Scares Me Sometimes

                          Tonight someone sent me an email with a spreadsheet in it. The extension was .xlsx, not something Office for the Mac understands. I clicked on it anyway to see what would happen. Here's what happened: Parallels fired up Excel in Windows in "coherence" mode so that my Windows version of Excel was running in it's own window--just like a regular application. Excel in Windows tried to open the file, but realized it was for Office 2007. Safari on Windows (apparently now my default browser) fired up and offered to download the compatibility pack. I did that and installed it,

                          Install the Parallels Tools!

                          Yesterday I did something in Parallels that I'm embarrassed to say I hadn't done before--it made a huge difference. I installed the Parallels tools in some guest OS's and compressed and defragmented their disks. The guest OS tools allow the guest OS to play better with the host. The biggest difference you'll notice is that the mouse "rolls" from the guest to the host OS without the need to push funny key combinations to "release the mouse." Not only that, drag and drop and cut and past work. Hurrah! Compressing my disk images cut them in half (6Gb to

                          Mounting OSX Directories in Parallels

                          I found this nifty trick for mounting OS X directories from Linux. This is handy when you're using Parallels on your machine and want to easily pass information back and forth. Parallels comes with a utility for doing this from Windows, but not Linux. The idea is to use sshfs, the SSH filesystem. I installed it easily on Ubuntu using apt-get (on Fedora, you'd use Yum) and then mounting a disk on my OS X file system is as simple as sshfs pjw@10.37.129.2:Documents "OSX Documents" "OSX Documents" is an empty directory on the Linux machine that serves as the

                          Using VMWare Fusion: A First Look

                          Last Friday I wrote that VMWare had released the second beta of Fusion, their virtual desktop for OS X. Over the weekend I took a little time to play around with it and had a few observations. Note that this is not a formal review--don't take it as one. First, Fusion works well, as promised. No major hiccups to report. I was able to set up a Fedora Core 6 image with only a few issues. Here are some of my discoveries and impressions: Fedora isn't one of the "supported" operating systems. I mistakenly chose "Redhat Linux" thinking that

                          Installing MS-DOS in Parallels

                          In the fun, but mostly useless, knowledge category, tonight I loaded MS-DOS 6.22 onto Parallels. I didn't have a copy on CD, only floppies and I couldn't get Parallels to see the USB floppy, but I was able to easily make floppy disk images of the originals and mount those. Here's how: Plug in the USB floppy drive and load the floppy. You should be able to see all the files from the Mac Finder window. Start OS X's Disk Utility application. Click on the floppy and then click "New Image" in the menu bar of Disk Utility. Select

                          Using Parallels to Simplify System Admin Tasks

                          One of the things I was most excited about with my MacBook Pro was the ability to run Parallels. People ask "if you like OS X so much why are you excited to be able to run other OSs?" Here's one reason. In my distributed applications class, I have my students set up and manage their own Linux server. For some of them it's the first time they've been root. They have to install jBoss, Axis, and other fun things before they can complete the assignments. As a consequence, I end up working on a Linux machine quite a

                          Changing Linux Screen Resolution In Parallels

                          I've had parallels running now for some time on my MacBook Pro and it's really nice to be able to fire up Windows or Linux when needed. I have a feeling this is going to come in real handy this fall when I'm teaching CS462 and have 40 students using Linux to do their assignment. I can keep a fresh image that's identical to the one their using and just fire it up when I need to try something out. One thing that's bothered me, however, is that Fedora didn't want to create screens bigger and 800x600. I knew
