I'm not sure if either support Windows ME though. :( Cheers Tim... Probably the first one I would try is VirtualBox OSE. If that doesn’t work, try VMware Server (the free one).

Open Source Edition 2. Binary download Both are free, but the binary contains both open and closed source code and is more feature rich. I recommend the binary. -FB VirtualBox comes as:
1. Open Source Edition
2. Binary download
Both are free, but the binary contains both open and closed source code and is more feature rich.
I recommend the binary.

Qemu sounds interesting. Of course, I had that installed to do conversions between VMware and VirtualBox. I tried doing a virtual machine on it, but it was chronically slow. I guess I was running in emulator mode, not in virtualization mode with the accelerator. Of course the other nice thing about Qemu is it emulates non-x86 architectures also. Cheers Tim... Hi.

They have a lot of disadvantages compared to already mentioned, but still i conder them as killer apps in certain circumstances. The first one - coLinux (www.colinux.org). It runs linux kernel by means of colinux kernel moduls and therefore can be used only for linux guests (it can be compiled for windows or linux hosts). The installation is very clean (only register colinux driver - if host is windows - and one driver for virtual network interface, equally easy is deinstallation). The main plus for colinux is the performance. I used to run several virtual machines on my notebook with full oracle stack - db, appserver, owb etc, in the same time some not so thin windows applications - and performance was perfectly acceptable. After playing with vmware, virtual box and some others - i think coLinux gives maximum performance which one can get with desktop virtualization. The next one is qemu (http://bellard.org/qemu/ - the probably oldest widely known virtualization solution). It is not the fastest one (though with accelerator module it is not so bad) - but it is the only virtual machine i know, which runs from usb stick and it doesn't require admin rights to run the network stack. And sometimes, if you have to work in very restricted environment, it may be very handy to have a stick with midsized linux distribution as a toolset.

Thanks for the info. It's good to know these things. :) The 64 bit support has only just been released for VirtualBox, so I wouldn't be surprised if there were some issues. It's just my preference, but I would always go with Linux as the host. :) Cheers Tim... Hi.

With VMWare it doesn't happen, I've 1GB of ram left and the cpu usage is below 10% when the guests are idle, so I've discarded Virtualbox for the moment, probably there's a bug with the current version running on Vista 64bits.
