Quick Review of Icaros on VirtualBox

[ferrellsl]

Well, to be fair, I have to say that ANY OS that I've run under VirtualBox has been dog slow and fraught with problems....except for MS-DOS and it doesn't even qualify as a real OS.  You really should try AROS on real hardware.  It's very responsive.

VirtualBox is not a good choice if your BIOS doesn't support Virtualization technology.

I understand, thats why I said I had full cpu virt. I have VT-x and VT-d in virtual box enabled in my intel cpu. I run lots of virtual box stuff (dual cpu windows 2000, xp, dual core freebsd, netbsd, linux, haiku) with no problem whatsoever, all with fast speed, bridged ethernet and between 1-3gb of memory per vm.

Icaros under virtual box was very flakey, the only times anything on virtualbox gave me issues.

I have quad core with 8gb ram on 64bit linux.

I meant to update my original 'quick review'

When I got home, I put Icaros on another machine where I have virtual box - it's a core 2 duo with SSD drive.

The difference was astonshing.

Yes, my Opteron 256 machine is an older machine, and doesn't support Virtualization - but why exactly is that important here?  That just means you won't get dual core support, but its not like Icaros needed another core.

I run Windows XP and Linux quite acceptably on the Opteron Box.

But in any event, yes a more modern machine, ran it great.

If the CPU doesn't have virtualization extensions Virtualbox needs to do para-virtualization, which involves one or more of a variety of hacks to trap and emulate any attempts by the OS use privileged instructions for example. It adds a tremendous amount of overhead whether or not the OS in question makes much use of the various functionality.
