I understand that it is just as easy to use the opensource tools (qemu/kvm/virt-manager) under Centos, but I've used VMware for years. In VMware, I created a new virtual machine and used the 2GB SanDisk as a physical partition instead of the normal virtual partition. I removed the sound bridge, added an extra virtual network and installed as normal. Once the installation was complete I removed a bunch of extra packages and converted the boot configuration to serial-only.

I would like to copy the image onto multiple CF cards. What software did you use to create your image file? Any help I could get would be appreciated.

I did this because I assume that most users are looking for a stripped down server and will add the features they need. In your case, you will have to install both the kernel-devel and kernel-headers packages, and maybe more. I haven't used Dahdi before, so I can't be more specific. Before I went through all that I would try to find a repository that already compiled the software for RHEL5. It appears that the epel repository has three dahdi packages: dahdi-tools, dahdi-tools-devel and dahdi-tools-libs. You might want to start there. Also - you shouldn't need to compile software on the ALIX itself. If you are going to work on software for your ALIX, I would recommend compiling it on a full-speed machine, or even a virtual machine. If you create an RPM spec script and package it as an rpm file, then you will only need to install the rpm with the binaries on the ALIX and you won't have all the extra stuff lying around. You also won't have libraries on the machine that aren't accounted for in your rpm database. Creating an rpm is not hard, and will save you mountains of time and headache in the long run. Check out <a href="http://software.freivald.com/centos" rel="nofollow">my software repository</a> for some examples of RPMs that I distribute. I try very hard to make them tidy and not cludgy. But it's always better if someone has already done the work for you. I use the EPEL and rpmforge repositories a lot and almost never have problems. Centos <a href="http://wiki.centos.org/AdditionalResources/Repositories/RPMForge" rel="nofollow">provides a link</a> that shows how to set everything up properly for using multiple repositories.

Yes, logically it should be automatically recognised, but didn't see any usb device detected. Will try out your commands later to check. I was just trying to mount my USB storage to /mnt mount point.

He said that the USB hardware was automatically recognized. If you tell me exactly what you are trying to do maybe I can point you in the right direction. Got a message back from Giulio.
