Virtual

sys_virt_status¶

Determine whether the host is a virtual machine or physical host by inspecting /proc/cpuinfo for hypervisor and virtualisation CPU flags.

Exit codes¶

• 0: Always

Output on stdout¶

• "virtual", "physical", or "unknown"

is_azure¶

Detect whether the host is running on Microsoft Azure. Checks for waagent.log containing "Azure" as the primary indicator.

Exit codes¶

• 0: Host appears to be on Azure
• 1: Host does not appear to be on Azure

is_aws¶

Detect whether the host is running on Amazon Web Services (EC2). Checks /sys/hypervisor/uuid, DMI product_uuid, and the instance identity document endpoint. Note: not updated for IMDSv2.

Exit codes¶

• 0: Host appears to be on AWS EC2
• 1: Host does not appear to be on AWS EC2

sys_virt_type¶

Detect the hypervisor or container runtime type. Tries virt-what first, then dmidecode, then falls back to /proc and filesystem heuristics.

Exit codes¶

• 0: Always

Output on stdout¶

• Virtualisation type string, e.g. "virtualbox", "vmware", "xen", "kvm", "qemu", "docker", "podman"
