Vmware Workstation 虛擬網路不正常

Vmware Workstation 的虛擬網路設定存放在 /etc/vmware/netmap.conf

但有時此檔案內容會不明原因的清空。如剛裝好的系統，此檔案是空的，因而在 VM 的網卡設定中無法選擇網路連線，或是 VM啟動後，沒有網路連線。

通常預設的內容如下

# This file is automatically generated.

# Hand-editing this file is not recommended.

network0.name = "Bridged"

network0.device = "vmnet0"

network1.name = "HostOnly"

network1.device = "vmnet1"

network2.name = "NAT"

network2.device = "vmnet8"

要修改網路可以使用 [System] -> [Virtual Network Editor] 的管理界面來修改。使用此界面，需要管理者的權限

進入後，看到的畫面

如上圖的設定，多加了一個網路連線，VMNet192，指定至另一個網路實體界面，用來分散網路連量。netmap.conf 的內容如下

# This file is automatically generated.

# Hand-editing this file is not recommended.

network0.name = "Bridged"

network0.device = "vmnet0"

network1.name = "HostOnly"

network1.device = "vmnet1"

network8.name = "NAT"

network8.device = "vmnet8"

network192.name = "VMNet192"

network192.device = "vmnet192"

相關的設定存放在 /etc/vmware/networking

修改內容後，執行 systemctl restart vmware-vmnet.service，讓設定生效。
