I installed GNURadio 3.1.2 on SuSE 10.2 in a virtual machine for VmWare 6.0. The installation is perfectly working also with the USRP. My system is a Centrino Duo T2300 with 2.5GB RAM.
I think it is really working since I've been using it for 2 months, now...
If someone is interested in a clean image of the vm, please tell me where to upload it since it is quite huge (2 GB zipped)
