64-bit rules?

[lucky9]

I have a question that's slightly off-topic. I've only run 32-bit and 32-bit pae systems on my computer, but my CPU has virtualization capabilities (AMD-V), which allows me to install 64-bit guest OSes in VirtualBox. I assume that the computing power of a 64-bit guest OS is still limited by the 32-bit computing power of the host. In other words, there would be no improvement in performance of a 64-bit guest OS versus a 32-bit guest OS. Am I correct?

64-bit Host will run a VM smoother than 32-bit Host will. Try breakout or something similar on a 64-bit Host. Then run it on a 32-bit Host. I've never tried to see if there is a difference in a Guest VM running 32 and 64-bit.

I had installed 64-bit MEPIS 8.0 years ago and found some of the programs I used frequently didn't run as well as they did on a 32-bit system, but I understand that times have changed and there have been major improvements to the stability and usability of 64-bit. Although I'm sticking with MX-14 (32-bit pae) for the foreseeable future, AntiX looks quite attractive as a second option. So I might try 64-bit AntiX with KDE in the future.

Fwiw, I think I now have a 64bit MX-14.2 install.

Over the weekend I spent some time converting a i386 install (MX-14.2-pae.iso) over to amd64.

I roughly followed the instructions here: http://www.ewan.cc/?q=node/90, at least until I ran into some problems around step 9.

1072 of the 1074 i386 packages have been switched over to amd64 packages. l currently have only one i386.deb package installed, fbxkb-antix, and I may end up removing it because it doesn't seem to work. I think fbxkb-antix might work if it was rebuilt for 64bit. (but I don't know where the source is).

I also don't have Adrian's gui installer (installer-mx) installed because it's currently only available in a i386 package. Actually it looks like the i386 package is installable, but it wants to remove a couple 64bit packages and install 32bit versions in their place, and install several other 32bit packages. I think a 64bit installer package could be built, the source is on github but it's not debianized.

Here's a summary of the differences between my 64bit install and the 32bit MX-14.2-pae install it started out as:

Hi Everyone,

So, are we going to see an official 64-bit version soon?

Thanks, Michael.

As we have said many times, that would probably only happen if and when a Community member or (preferably) group took it over as a project. That would mean not only development, but also maintenance and support. Same goes for MX KDE.

The current Development Team has enough to do already...

You can git clone my repo and then run qmake && make on a 64bit Linux and obtain the 64bit executable. You need of course all the qt dependencies to run qmake and make.

A day or so after I posted that I managed to debianize your source and build a 64bit "installer-mx" package. I installed it, but I haven't tried using it.

I created a snapshot iso of my 64bit install, but the LiveUSB I made with that iso wouldn't boot (the initrd still had the original i386 modules in it -- which might be the reason it wouldn't boot). I stopped playing around with it after that.

You would need the 64 bit modules in the initrd.gz if you are using a 64 bit kernel.

As Jerry has pointed out several times, there is a lot of work involved in building and supporting a 64bit version of MX.

[Adrian]

I wonder if it is that difficult... once we get that initrd with the 64bit modules then most of the packages just come from Debian with their 64bit versions, I think MX packages can all be built on 64bit arch without problems. It's double the work to build the CD, true, but I think most of it can be done automatically.

The building is relatively easy, though a bit time-consuming. However, there will be added 'issues' with things such as skype, netflix etc that don't seem to work too well on 64 bit linux.
