Linux system virtual machine configuration Internet Experience

Why the default virtual machine installation is complete, there will be two virtual network cards (VMNET1 and 8), corresponding to the host-only mode and NAT mode, in fact, there are three, there is a bridge to the physical network card (VMNET0), corresponding to the bridge mode.

First, explain the role of the virtual machine each network card set mode!

1, the configuration of the virtual machine NIC

Virtual Machine network card set NAT mode (Internet access available)

Virtual function access outside the network, the external network can not access the virtual machine, equivalent to the physical machine to do the internal network source IP conversion

/edit/Virtual network editor

Connect the NAT mode network card (tick connect the host virtual adapter to this network)

IP can be DHCP assigned (all set automatically) or manually (all statically assigned), remember to set DNS when static

Virtual machine NIC settings only host mode (no Internet access)

DHCP-Allocated network segments can be set in the Virtual network editor.

You can also cancel DHCP assignment, set the static IP of the virtual machine, set the IP of the virtual network card, set the static IP on the physical network card

Virtual machine NIC settings only bridge mode (network card connected to the physical machine) (Internet access)

The equivalent of a physical machine into a two-layer switch, virtual machine serial Two-layer switch, virtual machine and physical confidential network segment

The gateway can set the physical machine NIC to go out of the next hop.

2, the service opens (Ctrl+shlft+esc call Task Manager, view service)

VMware NAT Service//Use NAT mode to turn on

VMware DHCP Service//When using DHCP assignment to turn on

If the above service runs for a few seconds, it shuts down automatically

Edit script runs as Administrator

3, the System configuration (if the virtual machine is copied out, then the local area network will appear two as the MAC address, which

Will cause DHCP to be assigned no address, so if the copied virtual machines to remove the network card)

Modified:/etc/sysconfig/network-scripts/ifcfg-enoxxxx

Onboot=yes//Set up auto run on boot

The default is to obtain the IP automatically (if set static)

Bootprpto=static (static allocation) | DHCP (dynamic allocation)

Ipaddr=ip Address

gateway= Gateway

Netmask= Mask

Dns1=dns

Modified:/etc/resolv.conf//dns configuration file

IP address of nameserver DNS

Restart the service when you have finished modifying the configuration file: (usually below, or network becomes networking)

Service Network restart

Systemctl Restart Network

/etc/init.d/network restart

If you are still unable to access the Internet is a DNS address problem, it is best to obtain the IP DHCP DNS

Cannot operate on virtual machine when taking snapshot, insufficient capacity of hard disk saved by virtual machine and reason of saving snapshot failure

Ping baidu.com is my most commonly used to verify the use of the Internet means that the first ping will be very slow, should be, to

Find the route, all of you have to wait patiently.
