Could it be that you are using a Xen-enabled kernel? This is not supported. For more information see this link: http://software.intel.com/en-us/articles/does-vtune-analyzer-work-with-xen-enabled-kernels/
Could you look in /boot/config-`uname -r` . If there is a "CONFIG_XEN=y" and/or "CONFIG_X86_XEN=y" entry, then that kernel is Xen-enabled.
Also, is your Eclipse a 32 or 64 bit version?
Ok thanks. I think this is the issue.According to the Release Notes:
"The VTune Analyzer 9.1 for Linux* can be integrated only with the 32 bit version of Eclipse 3.2.1 on Intel 64 systems. Integration into a 64-bit version of Eclipse is not supported."
If youare able to try a32-bit version of Eclipse you mayhave more success.
Just to be extra cautious, you mention"No CONFIG_X86_XEN entry exists in the /boot/config-`uname -r` file". Does this go for "CONFIG_XEN=y" as well. If so, I will take this thread private to get some more information from you.
