Now that the vmware player beta supports USB2.0 for the USRP has anyone built a vmware image with gnuradio + gEDA + SVN, etc.?

I have an Ubuntu Edgy Eft VM for VMWare with GNU Radio from SVN installed; it's a little out of date, but it works and can easily be updated (I'm doing that right now). The virtual HD is 8 GB, but that could be reduced easily to save on size (I just copied it from another install that -did- require about 8 GB of HD space).

I don't have gEDA installed since it doesn't seem critical to GNU Radio compilation or execution.

I like using the VM: it's greatly convenient to for testing simple things such as the look of a GUI between (in my case, natively on) OSX, Linux (32-bit), and Windows (32-bit). Also: I've never gotten into 64-bit OS, but that could be done in VMWare as well since it supports both 32- and 64-bit computing (while the other competing programs do not, or so the reports state) ... can be useful for debugging those darn lib64 versus lib issues that pop up on the list every now and then.

In testing, USRP <-> USB2 <-> GNU Radio does provide 32 MBps r/w, so that's not a limiting factor. CPU speed is good (claim 95% of full rate), and disk I/O is OK (using the virtual HD as a native-OS file; supposed to be almost "full speed" when using an actual partition of disk dedicated to the VM).

The primary down-side is that graphics display update rates aren't great - this providing most of the slow-down when running GNU Radio GUIs that otherwise look and work well on their native platforms.

It's quite simple to make and pass along the files for a VMWare player for GNU Radio, though I don't know how large the resulting directory will be (after tar and bzip2) ... but it's a thought for quickly getting folks up and running in GNU Radio w/o all the hassle of installing libraries and such, making sure the USRP is recognized by udev, etc...

Also, where to host the VM tarball? - MLD
