VMware change IP

Modify /etc/hosts (ip)
Modify /etc/sysconfig/network (IP & gateway
Modify /etc/sysconfig/network-scripts/ifcfg-vswif[number]. By default, it should be 0

Or you can change it on fly:
ifconfig ifcfg-vswif0 inet netmask broadcast up


Useful tips (http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1000266):

To delete and recreate a virtual switch and Service Console from the command line:

Note: On your system the vswif, vmnic, vSwitch numbers and network settings are different.
1.
Run the following command to list the name of the vswif adapter:

# esxcfg-vswif -l



2.
Run the following command to delete the vswif adapter:

# esxcfg-vswif --del vswif0



3.
Run the following command to list the name of the vSwitch:

# esxcfg-vswitch -l



4.
Run the following command to delete the vSwitch:

# esxcfg-vswitch -d vSwitch0



5.
Run the following command to create the vSwitch:

# esxcfg-vswitch -a vSwitch0



6.
Run the following commands to create default port groups for vSwitch:

# esxcfg-vswitch -A "VM Network" vSwitch0
# esxcfg-vswitch -A "Service Console" vSwitch0



7.
Run the following command to create the vswif adapter:

# esxcfg-vswif --add --portgroup "Service Console" --ip=nnn.nnn.nnn.nnn --netmask=255.255.255.0 vswif0



8.
Run the following command to verify that the settings in the network file are correct:

# cat /etc/sysconfig/network

NETWORKING=yes
GATEWAYDEV=vswif0
HOSTNAME=host.domain.com
GATEWAY=nnn.nnn.nnn.nnn



9.
Run the following commands to list all of the network adapters and associate a vmnic which has a link status of up:

# esxcfg-nics -l
# esxcfg-vswitch -L vmnic1 vSwitch0



10.
Run the following command to verify that the vmnic is associated with the vSwitch:

# esxcfg-vswitch -l



11.
Ping an IP address to check for network connectivity. If the ping fails, remove the previous vmnic from the vSwitch and try another adapter that has a link status of up.

# esxcfg-vswitch -U vmnic1 vSwitch0
# esxcfg-vswitch -L vmnic2 vSwitch0



12.
Run the following command to change the vlan ID of a vSwitch:

# esxcfg-vswitch -p "VM Network 1" -v 10 vSwitch0



13.
If you make any manual changes to /etc/sysconfig/network, run the following command to restart the network service:

# service network restart
