Xen Virtual Ethernet Drivers For Mac

My client has a XenServer 6.0.2 installation with 2 Window Server 2008 R2 virtual machines. Whenever the virtual machines are rebooted they lose their IP settings (IP address, subnet, gateway). Each time after a reboot I need to login to each VM via XenCenter and re-apply the required static IP settings. This causes issues with connected iSCSI drives within each VM - drives need to be reconnected after each reboot. Remove ghosted NICs This can happen if you set your network configuration prior to installing the XenServer tools on the guest.

Virtual Ethernet Adapter

Open device manager on the server, and ensure you have 'Show hidden devices enabled' (View menu-Show hidden devices). If you see any additional network adapters listed, such as Realtek RTL8139 devices, remove them from device manager. Then double-check your network adaptor is set to the correct IP address, and reboot. It should retain the IP settings you configure.

This problem occurs as the XenServer tools install a new paravirtualised network adaptor, using the same IP settings as the initially configured virtualised network adaptor (Usually a virtual Realtek NIC), without removing the settings from the old NIC. This causes an IP conflict, and the new NIC reverts to automatic configuration. Further reading. (Archived.).

Log in as local admin account Open a command prompt Issue the command set devmgrshownonpresentdevices=1 Launch Device Manager by typing devmgmt.msc in the same command prompt session (so the device manager session “sees” the environment variable) In Device Manager select View - Show hidden devices Now the Ghosted NIC’s (RTL8139+) should be visible under Network Adapters and you should be able to just uninstall them, just by right-clicking them and select uninstall After uninstalling the ghosted NICs, set the IP address on your nic again and it will stick.
