仮想ネットワークの XML 構成を変更するために、その構成をエディターで開く virshop のサブコマンドはどれですか? (パラメータを指定せずにサブコマンドのみを指定します。)
仮想ネットワークの XML 構成を変更するために、その構成をエディターで開く virshop のサブコマンドはどれですか? (パラメータを指定せずにサブコマンドのみを指定します。)
正解:
net-edit
Explanation:
The subcommand of virsh that opens the XML configuration of a virtual network in an editor in order to make changes to that configuration is net-edit1. This subcommand takes the name or UUID of the network as a parameter and opens the network XML file in the default editor, which is specified by the $EDITOR shell variable1. The changes made to the network configuration are applied immediately after saving and exiting the editor1.
:
1: net-edit - libvirt.

仮想化ホストが Intel VT-x サポートを提供しているかどうかを判断するには、/proc/cpuinfo ファイルでどの CPU フラグを検索する必要がありますか?
正解:
vmx
Explanation:
Intel VT-x is Intel's hardware-assisted virtualization technology and is required to run hypervisors such as KVMefficiently. According to Linux and KVM documentation, support for Intel VT-x can be verified by checking the CPU flags listed in the /proc/cpuinfo file.
The specific flag that indicates Intel VT-x support isvmx. This flag appears in the flags section for each processor core if VT-x is available and enabled in the system firmware (BIOS or UEFI). The presence of vmx confirms that the CPU supports hardware virtualization extensions required by KVM.
If the flag is absent, virtualization may either be unsupported by the CPU or disabled in the firmware settings.
For AMD processors, a different flag (svm) is used.
Virtualization documentation consistently references the vmx flag as the authoritative indicator for Intel VT-x support. Therefore, the correct and documented answer isvmx.
