透過 Virtualbox 的使用說明: https://www.virtualbox.org/manual/ 可以了解一個 Virtualbox 的虛擬機器, 若啟用 ICH9 Chipset, 最多可以支援 36 片網路卡.
Virtualbox 虛擬機器最多可以支援 36 片網路卡
如下圖所示:
至於 host-only 的網路卡設定 正好介於 bridged 與 internal 網路設定特性之間. 也就是說 host-only 網路卡設定與 bridged 網路卡設定類似, 可以想像各採用 host-only 設定的虛擬機器與 host 機器的網路線全部接到同一台network switch (網路交換器), 不僅可以彼此連線, 也能與 host 連線. 但是 host-only 網路卡設定與 bridged network 設定的差異是, host-only 無需與任何實體網路卡進行橋接, 而是透過位於 host 機器上的虛擬網路卡達到與各虛擬機器及 host 網路相連的目的.
而 host-only 網路卡設定與 internal 網路設定類似的地方, 在於這些設定為 host-only 網路卡相連的虛擬機器無法與 host 以外的網路相連.
另外, 透過 bridged 網路卡設定說明: https://www.virtualbox.org/manual/ch06.html#network_bridged, 我們也可以得知, 所謂虛擬機器的橋接網路連線設定, 就是要讓虛擬機器透過 host 上的實體網路卡, 與外部的網路相連, 成為一台與 host 位階相同的伺服機器.
虛擬機器與虛擬硬碟的 uuid 編號
至於在使用 Virtualbox 的過程, 當使用者需要設定虛擬機器的 uuid 時, 可以透過下列 Python3 程式產生 uuid.
import uuid
print(uuid.uuid1())
#UUID('5361a11b-615c-42bf-9bdb-e2c3790ada14')
接著再利用:
VBoxManage startvm "Your VM name", 使用 Virtualbox 指定的 uuid, 或者自行指定虛擬機器的 uuid.
VBoxManage startvm "Your VM name" 5361a11b-615c-42bf-9bdb-e2c3790ada14
由於虛擬機器的 uuid 只用於 global configuration data 的設定, 以及各虛擬機器啟動時的基本辨識, 因此也可以直接在設定檔案中更改, 只要前後呼應即可. 但是虛擬硬碟的對應 uuid 則與 .vdi 檔案綁定, 因此根據 https://www.virtualbox.org/manual/ch08.html#vboxmanage-clonevdi 中的說明, 可以利用:
VBoxManage clonemedium Master.vdi Clone.vdi
手動進行 vdi 檔案的複製, 基本概念是存在同一個 host 中的虛擬機器個別要有一個 uuid 編號, 而這個編號會在 host 中所安裝的 Virtualbox 套件中, 經由 preferances 設定檔案與個別虛擬機器引用時進行對應, 至於虛擬硬碟的 uuid, 除了與 .vdi 綁定, 也會在個別虛擬機器的設定檔案中前後出現兩次.
但是若 Master.vdi 在下 VBoxManage.exe 指令的 Host 機器上, 已經註冊在虛擬機器中, 則必須要先更改虛擬機器的硬碟 .vdi 檔案之後, 才能夠執行 clonemedium 指令:
也就是必須先執行:
"c:\Program Files\Oracle\VirtualBox\VBoxManage.exe" internalcommands sethduuid registered_vdi.vdi
然後再執行:
"c:\Program Files\Oracle\VirtualBox\VBoxManage.exe" clonemedium registered_vdi.vdi new_vdi.vdi
之後若在同一個 Virtualbox 的主體中利用此一 new_vdi.vdi 建立虛擬機器, 就不會發生硬碟 uuid 編號重複的問題.
至於 Global configuration data 檔案的存放位置, 根據 https://www.virtualbox.org/manual/ch10.html#idm8784 的說明, 在視窗操作系統會存在 HOME/.VirtualBox 目錄, 以 xml 格式儲存, 在 Linux 與 Solaris 操作系統中, 則儲存在 HOME/.config/VirtualBox 目錄中, 假如是 OS X 操作系統, 則會儲存在 HOME/Library/VirtualBox.
值得一提的是, 當操作系統中 Virtualbox 沒有開啟時, 使用者可以直接修改上述的相關設定檔案, 例如, Virtualbox 的 GUI 介面中 ,只能讓一個虛擬機器啟用 4 片網路卡, 假如使用者需要啟用第 5 ~ 36 片網路卡時, 可以根據 https://www.virtualbox.org/manual/ch08.html#idm4023 的說明, 利用 VBoxManage modifyvm 指令進行設定, 或者直接編輯相關的設定檔案達成.
Virtualbox 虛擬機器檔案跨操作系統應用
以下則是在 Windows 7 Pro 電腦上啟動 Vt-x, 建立 64 位元的 Windows 7 虛擬機器後, 將虛擬機器檔案轉到 Ubuntu 的 Virtualbox 上, 然後根據上述說明, 啟動 36 片虛擬網路卡的過程畫面:
首先是從網路上下載 Windows 7 64 位元的虛擬機器檔案壓縮檔, 然後解開壓縮檔, 準備在 Ubuntu 上的 Virtualbox 建立虛擬機器:
接著是解開壓縮檔案之後的 Windows 7 虛擬機器檔案, 其中包括 .vdi 與兩個虛擬機器的設定檔:
利用解開壓縮的 .vdi 檔案, 在 Ubuntu 上的 Virtualbox 建立虛擬機器, 每一個虛擬機器都對應一個 .vdi 檔案與兩個設定檔案:
接下來是 Ubuntu 上的虛擬機器準備開機的畫面:
接著是虛擬機器在 Ubuntu 上開啟 Windows 7 的畫面, 測試 V-rep, 可攜 Python3 程式環境啟動, 開啟 Leo Editor 與 Jypyter 的畫面:
最後則是在 Windows 7 虛擬機器中創建 36 張虛擬網路卡的畫面:
虛擬機器設定檔案
以下則為創建 36 片虛擬網路卡的虛擬機器設定檔案:
