    3939= 【問題碎碎念】 =
    4040 * '''drbl_bridge_kvm_patch'''：再開機時產生 bridge (br0) 之後會遇到找不到 NFS server，而產生 kernel panic。但產生的 bridge 若名稱為 bridge (eth0) 則可以正常運作。
    41    * 猜測掛載 NFS 時只會使用正常名稱的網路設備 eth (而非 br0)
    42  * '''drbl_PXE_KVM-VM_deploy'''：再 deploy KVM VM 時網路會有一小段時間中斷，dmesg 時會出現 bridge 設備的相關訊息(浸入混亂模式...等等)。
    43    * 但有趣的是同樣是用 bridge 方式的 Xen VM，卻不會有其狀況，可能狀況是 KVM 額外用的 tap 機制會先 down 原來的網路設備再 bridge 過去，導致短暫時間的網路中斷，或許可以朝 KVM 的 tap 運作這方向研究一下。
