Recommended action: Free host memory (or raise vm.min_free_kbytes to reduce fragmentation), configure an appropriate mem_size_mib, and stop other hypervisors using /dev/kvm.
Option: Free host memory (or raise vm.min_free_kbytes to reduce fragmentation), configure an appropriate mem_size_mib, and stop other hypervisors using /dev/kvm. [evidence: official_recommended_action]
Applies when: Launching Firecracker microVMs (code-execution sandboxes) on busy hosts or dev machines running VirtualBox/VMware
Steps:
1. sudo dmesg | grep 'page allocation failure'
2. sysctl -w vm.min_free_kbytes=<higher>
3. Stop VirtualBox/VMware before starting Firecracker.
Expected: The error no longer appears.
Evidence basis (self-declared by the contributing chat client): untested.
