Lpi LPIC-3 Exam 305: Virtualization and Containerization (305-300日本語版) - 305-300日本語무료 덤프문제 풀어보기
KVM 仮想マシン内で Linux を起動するために直接 Linux ブートを使用する場合、Linux カーネルのパラメータを指定するためにどの KVM パラメータが使用されますか?
(値やパラメータを指定せずにオプション名のみを指定します。)
(値やパラメータを指定せずにオプション名のみを指定します。)
정답:
-append
Explanation:
When usingdirect kernel bootingwith KVM/QEMU, the-appendoption is used to passkernel command-line parametersto the Linux kernel. This allows administrators to specify boot-time options such as root filesystem location, console settings, or debugging flags.
Official QEMU documentation lists -append as the correct parameter for kernel arguments, making this answer correct.

準仮想化マシンではなく完全仮想化マシンを作成するには、Xen ゲスト ドメインの構成ファイルのオプション ビルダーでどの値を設定する必要がありますか?
정답:
builder = "hvm"
Explanation:
In Xen virtualization, guest domains can be created using either paravirtualization (PV) or hardware-assisted full virtualization, also known as HVM (Hardware Virtual Machine). According to official Xen documentation, the builder option in a Xen guest domain configuration file determines the type of virtualization used when creating a virtual machine.
To create a fully virtualized (HVM) guest, the configuration file must explicitly set the value of the builder option to "hvm":
builder = "hvm"
This instructs the Xen toolstack to use hardware-assisted virtualization features provided by the CPU, such as Intel VT-x or AMD-V, allowing unmodified guest operating systems to run. Fully virtualized guests behave like physical machines and can run operating systems that are unaware of Xen.
If the builder option is omitted or set to the default paravirtualized builder, Xen expects a PV-capable kernel, which requires guest operating system modifications. HVM guests, by contrast, rely on device emulation and hardware virtualization support.
Virtualization documentation clearly distinguishes between PV and HVM guests and identifies builder =
"hvm" as the required configuration for full virtualization. This setting is fundamental when deploying operating systems such as Windows or standard Linux distributions without Xen-specific kernels.
Therefore, the correct and documented value is builder = "hvm".
