Check Processor Compatibility¶
Before installing Clear Linux* OS, check your host system’s processor compatibility using one of the following options:
Note
This does not check other system components (for example: storage and graphics) for compatibility with Clear Linux OS.
Option 1: Use the clear-linux-check-config.sh script on an existing Linux system¶
Download the clear-linux-check-config.sh file.
If a browser is not available, use:
curl -O https://cdn.download.clearlinux.org/current/clear-linux-check-config.sh
Make the script executable.
chmod +x clear-linux-check-config.sh
Run the script.
Check to see if the host’s processor is capable of running Clear Linux OS.
./clear-linux-check-config.sh host
Check to see if the host is capable of running Clear Linux OS in a container.
./clear-linux-check-config.sh container
The script prints a list of test results similar to the output below. All items should return a SUCCESS status. This example indicates the host’s processor supports running Clear Linux OS.
Checking if host is capable of running Clear Linux* OS SUCCESS: 64-bit CPU (lm) SUCCESS: Supplemental Streaming SIMD Extensions 3 (ssse3) SUCCESS: Streaming SIMD Extension v4.1 (sse4_1) SUCCESS: Streaming SIMD Extensions v4.2 (sse4_2) SUCCESS: Carry-less Multiplication extensions (pclmulqdq)
Option 2: Use a Clear Linux OS live image on a non-Linux system¶
Download either the Desktop or Server version of the live image ISO.
Follow the instruction to Create a bootable USB drive using Etcher*.
Boot up the Clear Linux OS live image on the USB.
Check compatibility as follows:
Desktop version:
Open a terminal.
Check compatibility.
sudo clr-installer --system-check
Server version:
Log in as root and set a password.
Check compatibility.
clr-installer --system-check
Expected output for a compatible host processor:
Checking for required CPU feature: lm [success] Checking for required CPU feature: sse4_2 [success] Checking for required CPU feature: sse4_1 [success] Checking for required CPU feature: pclmulqdq [success] Checking for required CPU feature: ssse3 [success] Success: System is compatible
