I installed the latest OpenCL version (Intel® CPU Runtime for OpenCL™ Applications 18.1 for Linux* OS (64bit only)) on a Ubuntu 16 virtual machine.
I run a program (in this case Hashcat) and I get this errror:
hashcat (v5.1.0) starting... OpenCL Platform #1: Intel(R) Corporation ======================================== * Device #1: Common KVM processor, 757/3029 MB allocatable, 2MCU Hashes: 4 digests; 2 unique digests, 1 unique salts Bitmaps: 16 bits, 65536 entries, 0x0000ffff mask, 262144 bytes, 5/13 rotates Applicable optimizers: * Zero-Byte * Single-Salt * Brute-Force * Slow-Hash-SIMD-LOOP Minimum password length supported by kernel: 8 Maximum password length supported by kernel: 63 Watchdog: Hardware monitoring interface not found on your system. Watchdog: Temperature abort trigger disabled. clCreateContext(): CL_DEVICE_NOT_AVAILABLE
I am using an Intel i5 3470 CPU.
What is the meaming of that error? How can I fix it?

Based on the output you provided, I am assuming you are running the code in full virtualization mode using QEMU, which provide a CPU-emulation layer. In this case, Intel OpenCL Runtime is unable to execute the OpenCL kernel on the "Common KVM processor", because the runtime is looking for Intel CPU.

Dear Andrey,
I get a similar issue. Where would you recommend to look for an appropriate OpenCL CPU driver for QEMU KVM, Ubuntu 18? Is it possible at all?
Thank you.
Danylo.
