networkを再起動（停止＋起動）
既存のリース情報があれば削除しておきます
# network 停止
sudo virsh net-destroy default
# leases を削除
sudo rm -f /var/lib/libvirt/dnsmasq/default.leases
sudo rm -f /var/lib/libvirt/dnsmasq/default.status 2>/dev/null || true
sudo rm -f /var/lib/libvirt/dnsmasq/virbr0.status 2>/dev/null || true
# network 起動
sudo virsh net-start default
vm起動時にmacアドレスを指定
virt-install \
--network network=default,model=virtio,mac=52:54:00:ff:ff:10 \
（以下略）
vm起動後に確認
$ virsh domifaddr vm10 --source lease
名前 MAC アドレス プロトコル アドレス
