KVMのインストール
Tecmintの記事を参考にubuntuサーバにKVMをセットアップする。
Step 1: Check Virtualization Support in Ubuntu
$ egrep -c '(vmx|svm)' /proc/cpuinfo 12 $ sudo apt install cpu-checker $ sudo kvm-ok INFO: /dev/kvm exists KVM acceleration can be used $
Step 2: Install KVM on Ubuntu 20.04 LTS
$ sudo apt install -y qemu $ sudo apt install -y qemu-kvm $ sudo apt install -y libvirt-daemon $ sudo apt install -y libvirt-clients $ sudo apt install -y bridge-utils $ sudo apt install -y virt-manager

Step 3: Creating a Virtual Machine in Ubuntu
$ qemu-img create -f qcow2 ssp0.qcow2 150G Formatting 'ssp0.qcow2', fmt=qcow2 size=161061273600 cluster_size=65536 lazy_refcounts=off refcount_bits=16 $
~$ virt-install -n ssp0 -r 8192 --disk=ssp0.qcow2,bus=virtio --graphics vnc,password=vnc,listen=0.0.0.0,keymap=ja --noautoconsole -v --boot hd --cdrom ubuntu-20.04.2-live-server-amd64.iso Starting install... Domain installation still in progress. You can reconnect to the console to complete the installation process. $
