安裝 KVM 模板

1. 線上下載安裝
/usr/share/cloudstack-common/scripts/storage/secondary/cloud-install-sys-tmplt \
-m /storage/nfs/s \
-u http://download.cloudstack.org/systemvm/4.15/systemvmtemplate-4.15.1-kvm.qcow2.bz2 \
-h kvm -F

2. 本地安裝
/usr/share/cloudstack-common/scripts/storage/secondary/cloud-install-sys-tmplt \
-m /export/secondary \
-f /root/systemvmtemplate-4.15.1-kvm.qcow2.bz2 \
-h kvm -F

全域設定
cpu.overprovisioning.factor 2.0 //CPU超配
mem.overprovisioning.factor 2.0 //記憶體超配，即2GB變4GB
secstorage.allowed.internal.sites 0.0.0.0/0 //從該網段下載ISO或模板,後期搭建ngix伺服器可修改
management.network.cidr 192.168.100.0/24 //管理網段，可不修改，但會有警報資訊

KVM : 所有VMs都需要支持virtio驱动。Linux kernel versions 2.6.25和更高版本中已经安装了这些驱动。管理员必须在virtio的配置文件中配置CONFIG_VIRTIO_BALLOON=y。

vim /etc/cloudstack/agent/agent.properties
guest.cpu.mode=host-model
host-model 表示從可用的CPU模型中選擇一個與宿主機最接近的。
