I don't like Virtualbox anymore, since it trashed my virtual machine probably with this bug.. Which will be fixed in the next update. But I like Sun, their hardware is excellent.
But Virtualbox, well it eats cpu while idle also. I don't mind paying a buck for something stable.
So Parallels 5 or Fusion 3?
I use the xfce version of Ubuntu. Both Parallels and Fusion supports 9.04 of Ubuntu. I have learnt from experience that it is a bad idea to run a more recent OS than what is officially supported.
What is nice with Fusion 3 (vs Fusion 2) is that it now has the vmrun command-line utility. But Parallels also has a command line control.
In the end I decided to go for safety, since I have had a rather trouble-free time with Fusion 2 i will continue with Fusion 3. I haven't tried it, but another advantage might be that VmWare runs on other platforms, such as Linux. I think in theory it should be possible to run a Fusion virtual machine on VmWare server.

Parallels 5
I downloaded Parallels 5 and tried it out.
Unfortunately it could not migrate my Linux virtualmachine. I pointed out the .vmdk file, but it answered this:
I did continue, it made a new file. Now I tried to make a brand new Linux Machine, and use th imported file. Well it worked sort of, but after Grub I got the message "Invalid or unsupported executable format". I don't enjoy messing with computers, so that means no parallels for me. UPDATE: No no, it seems it is Virtualbox that has messed up the virtual machine. Before trying out Parallels I needed more space on the HD, so I asked virtualbox to delete some unused snapshots. Something must have gone really really bad in the merge. Because now I can't start the machine in virtualbox either. Perfect that I have a backup copy. Not so perfect it is about a month old.
Back to Parallels, I also tried to run windows XP which I use to run Internet Explorer, it seemed to run fast and could be integrated with Mac in a smart way.
What is the next step? I am not sure. I am quite shocked that Virtualbox has messed up my computer.
Unfortunately it could not migrate my Linux virtualmachine. I pointed out the .vmdk file, but it answered this:
No active volume is selected or no operating system is installed on the specified volumes. The selected volumes will be migrated to Parallels virtual data disks. Are you sure you want to continue?

VirtualBox lot of CPU while linux idle
At least steady 20% cpu use on Os-X virtualbox 3.1.4 despite linux-virtual image installed in ubuntu 9.10. My wife complains about the sound from my computers fans.
It is difficult to get fast information about what is the problem. I guess from this thread it has to do with the Linux kernel.

I think I need to recompile the kernel:
https://help.ubuntu.com/community/Kernel/Compile
Now it looked like a reasonably easy thing, but it didn't work for me, I never got the promised .deb file of the new kernel. I like Linux but don't really like to mess with Linux problems, so I give up fast as usual. It try Parallels instead for the first time.
