搬移步驟
先把要搬移的vm給關機， proxmox-1 建立 /mnt/backup ，然後再執行
vzdump --mode stop --dumpdir /mnt/backup --compress lzo VMID
- --mode stop : 會做較完整的備份，但會執行會比較久
- --dumpdir : 指定檔案輸出的位置
- --compress : 會做壓縮，目前有 gzip, lzo，預設是0
- --bwlimit : 指定要寫入的IO (我沒有用)

跑完之後，就把 /mnt/backup 底下的檔案， scp 到 proxmox-2 ，再去執行 qmrestore vzdump-qemu-VMID-date.vma.lzo VMID
