You might see the following error when you try to configure the network with VMware Player 3 on SLES 11:

Jan 12 14:57:34.761: vmx| VNET: MACVNetPortOpenDevice: Ethernet0: can't open vmnet device (No such device or address)

This error indicates that the VMX file might have been opened by another VM. To work around this issue, you must update the MAC address in the VMX file as follows:

  1. Open the VMX file in a text editor.

  2. Copy the MAC address from the ethernet0.generatedAddress field.

  3. Open the /etc/udev/rules.d/70-persistent-net.rules file from the guest operating system.

  4. Comment out the original line, then type a SUBSYSTEM line as follows:

    SUBSYSTEM=="net", DRIVERS=="?*", ATTRS{address}==<MAC address>, NAME="eth0"

  5. Replace <MAC address> with the MAC address you copied in Step 2.

  6. Save and close the file.

  7. Open the VM in VMware Player.
