  • 1.  error bringing up interface eth0 (host only network adapter)

    Posted Jan 06, 2011 03:15 PM

    Hi All,

    I have a RHEL virtual machine running on VMWare Server. We have installed ESXi 4.x onto another box, and then used VMWare vCentre Converter Standalone to copy that virtual machine from our VMWare Server to ESXi.

    The original virtual machine has the following configuration:

    [root@CMV1UPM network-scripts]# cat ifcfg-eth0
    DEVICE=eth0
    BOOTPROTO=static
    ONBOOT=yes
    TYPE=Ethernet
    ETHTOOL_OPTS=
    IPADDR=10.230.14.225
    NETMASK=255.255.252.0

    [root@CMV1UPM network-scripts]# cat ifcfg-eth1
    DEVICE=eth1
    BOOTPROTO=static
    ONBOOT=yes
    TYPE=Ethernet
    ETHTOOL_OPTS=
    IPADDR=10.64.11.60
    NETMASK=255.255.252.0
    GATEWAY=10.64.8.1

    When I copy it over to the new ESXi server, for the new virtual machine, I want to keep the IPADDR=10.230.14.225 for eth0. At the moment, when I do service network restart, I get

    Bringing up interface eth0: Error, some other host already uses address 10.230.14.225 [FAILED]

    This is confusing me. In VMWare Server, for eth1 I would use a bridged network adapter, and for eth0 I would use a host only network adapter. But how can I create those in ESXi using vSphere Client console? At the monent, my network looks like the below:

    Thank you.

    Networking in ESX(i) is different than what is available in the desktop products. ESX(i) host NIC cards are uplinks from the virtual switches to physical switches etc. Each guest has a virtual NIC(s) connected to a virtual switch.

    Please provide a little more information about what you want to accomplish here?

    If you are wanting to create an isolated network you will need to create a separate vSwitch and attach on vNIC to each vSwitch.
