Identify CPU features that support performance and isolation for full virtualization on an x86_64 host.
Which pair is hardware virtualization assistance?
Intel VT-x and AMD-V provide CPU-level virtualization support for running guest operating systems.
Detailed explanation
Incorrect. SSE and AVX are instruction-set extensions, not the main hardware virtualization features.
Correct. Intel VT-x and AMD-V are CPU virtualization extensions.
Incorrect. ext4 and XFS are filesystems.
Incorrect. SSH and TLS are network-security technologies.
Try it yourself
An example you can run in a temporary verification environment.
grep -Em1 -o 'vmx|svm' /proc/cpuinfo || trueExpected result
公開されていればIntelはvmx、AMDはsvm。非表示の環境もあるKey points
- VT-x
- AMD-V
- CPU virtualization assistance
Notes
- Environment: x86_64 Linux。nested環境ではflagが隠れる場合あり
- Use a disposable VM or container when validating lifecycle commands.
- Exact command output can vary slightly by distribution and runtime version.
Foundation review
Identify the layer
A supported CPU does not by itself prove that virtualization is enabled in firmware or exposed to a nested guest.
Check the side effect
Inspect the processor flags and firmware setting in a non-production host before enabling a virtual-machine workload.
