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。
