QEMU-KVM in Arch Linux

Check Virtualization Support

lscpu | grep -i Virtualization

• VT-x for Intel
• AMD-Vi for AMD

Ensure that your kernel includes KVM modules

Goals

• To provide Nix repositories with an easy and standard way to reference other Nix repositories.

• To allow such references to be queried and updated automatically.

• To provide a replacement for nix-channel, NIX_PATH and Hydra

How to check file integrity with shasum

---

For verifying the integrity (but not authenticity of data, i.e., who authored it or the origin of the file) of a file, it is necessary to run a checksum function on the file which will output a value and compare it to a previously stored checksum value; if both values match, we can be relatively confident that the file hasn't been tampered with or altered.

You might be asked to verify a file's sha1sum or sha2sum–-all this means is calculating and verifying the cryptographic sha1 or sha2 hash value or digest included in the file.

Various commands and methods for verifying shasum 1 or 2:
