If the underlying hardware indeed is new and equipped with fast CPUs there's something else that's wrong and I will need to investigate that. I assume (hope/guess) the i440FX is more like what platform was used to build the kernel or similar rather than being an actual chip being in use. However, dmidecode says something completely different: # dmidecode 2.12 Same info from dmesg: $ dmesg | grep -i intelĬPU0: Intel Xeon E312xx (Sandy Bridge) stepping 01 However, this being a virtual environment - something that's new to me - I'm unsure if I can trust it 100%. Model name : Intel Xeon E312xx (Sandy Bridge)Į3-12xx Sandy Bridge is something like 5 years old and could be an explanation why my current bare metal servers from the same era of processors actually are faster. However, /proc/cpuinfo tells me that they are something rather different: processor : 0 You must run on an Intel processor with the required virtualization support.I'm evaluating a private cloud solution built on kvm and so far I'm not getting the speed of the system that I need for my purposes.Īccording to the vendor the underlying machines should be equipped with "state of the art" E5-4620 processors. On linux you can check this by executing: More specifically it requires support for extended page table (EPT) and a VM-tagged TLB (VPID). When this does not print "OK", you may need to look for another system. Note 1: You may need to explicitly enable (some of) these feature in your (updated) BIOS. Note 2: Fides requires hardware virtualization support. While theoretically possible, none of the commonly used hypervisors such as VirtualBox, VmWare and Virtual PC (or at least to my knowledge) are capable of emulating virtualization hardware. Fides can thus not be executed on top of a hypervisor. This includes Linux kernel modules (e.g., KVM) that basically turn Linux into a hypervisor. TheFidesSuite/Fides/Fides/Driver/vmm_interface.h:24:29: fatal error: spm_environment.h: No such file or directory In file included from /TheFidesSuite/Fides/Fides/Driver/secure_loader.h:25:0,įrom /TheFidesSuite/Fides/Fides/Driver/secure_loader.c:23: SPMCompiler::SPMCompiler::SPMCompiler( char &ID ) TheFidesSuite/Toolchain/Compiler/Core/spmCompiler.cpp:31:1: error: Problem: One user complained that compilation of The Fides Suite ended in the following error: See the Blue Pill work by Joanna Rutkowska for more details. Problem:When Fides is started, the driver fails to make run Also it seems that g++ must be the default compiler for cpp Situation 2 Solution:Make sure that llvm/clang is installed correctly with cmake. Problem: Fides tests "instances" and "secure communication" fail OR Applications exit with the error message "Failed to allocate bytes to load " Recheck the System Requirements Situation 3 Solution: Most likely you are trying to run Fides on a system that is not suitable. Solution: SPMs fail to allocate enough memory. The KVM hypervisor requires: an Intel processor with the Intel VT-x and Intel 64 virtualization extensions for x86-based systems or. This is caused because allocated pages must be locked in memory, meaning that they should never be swapped to disk. A security setting in the Linux kernel places a limit on the number of pages each process can lock in memory.There are a number of ways you can get information about the processor on your Linux system. I’ll show you my favorite tool for this task along with a few additional ways to check CPUs in Linux. This is the simplest command that shows the CPU information in a simple and concise output. You can see the architecture of your system, number of processors, vendor information, cache information, processor speed etc. It’s easier to remember as well because it is similar to the ls command.
