  • Thread-topic: Xenperf cannot work after I installed Xen on CentOS 6


                The problem I incurred is that I cannot use “xenperf” after I installed Xen. When I try to execute xenperf, the console shows: “Error getting number of perf counters: 38 (Function not implemented)”.

                The OS where I installed Xen is CentOS 6.5. I installed Xen following the instruction on the website of Xen4CentOS, and the version of Xen is 4.2. I believe I have successfully installed Xen, as I am able to execute commands such as “xen list”, “xentop”, etc. In addition,  I managed to create VM using Xen with the tool of virt-manager.

                However, xenperf cannot work as I mentioned above.

1). Does such issue incur because the Xen (specifically, I mean the Dom0) I installed by  Xen4CentOS does not support xenperf ?

2). As I know CentOS 6  does not support Xen now, so do I have to build the Dom0 OS that supports Xen myself ?


Thanks !!!
