The license comes with. Be sure to check the release notes to see if the exact OS you are installing on is supported or not.
If *NOT* consider the two system approach: installing the linux remote agent (vtserver, it's a separate tar ball on the VTune distribution, and has an "install.sh" instead of an "install", if memory serves).
Depending, there's a better chance that vtserver will install in a currently unsupported Linux environment than the whole of vtl/vtlec.
THEN, you find a supported OS on the same network, and install vtl/vtlec there.
From that point, you sit at vtl/vtlec and lauch sampling and callgraph activities over to the remote collector, and the information is sent back to you automatically.
I hope this helps!
PS: some folks purchase VTune for Windows, which has the same linux remote agent vtserver. In that two system approach, you install vtserver on the Linux server, and run profiling sessions on your apps from a WINDOWS VTune version. Works like a champ. I used the Linux to Linux approach in my answer above because you said you had the VTune for Linux product, not the VTune for Windows product. FYI only.
My understanding is that EM64T support for VTune 3.0 is:
-- sampling only (no callgraph)
-- vtserver only (that install.sh I talked about, not install for vtl/vtlec)
The next release of VTune for Linux, version 8.0, will have a full spectrum of EM64T support. That will be available for limited test in August of this year; will be generally available in November of this year.
When you buy or register for an evaluation copy of VTune, you get a license file (.lic), and that .lic file should work for all the software in the distro, vtl/vtlec (command line and GUI), and the linux remote agent vtserver, also sometimes called the RDC or remote data collector.
When I do this, install.sh usually prompts me for the license location if it can't find it. Maybe you have more than one .lic file, and maybe it's just for the Intel compilers, or some other software other than VTune?
IF however you are using the .lic file that came with your software, I'd run a find command, make sure no other .lic files are in the same subdirectory, and if there are, rename them (remove the .lic extension) make sure only your one true license is in the subdir.
If this doesn't work, and you are using evaluation software, you can register and get another eval license at our download site:
I'm sorry to inform you that 2.6 kernels are not yet formally supported. We do have support for some 2.6 kernels in an update for the Microsoft* Windows*-based VTune analyzer, but we do not have anything yet for the Linux*-based product.
