Oracle® VMWindows Paravirtual Drivers Installation Guide Release 2.0 for Microsoft Windows
E15298-02 May 2010
6.4 Network Devices May Fail
If you install the Windows PV drivers into aguest with the vif type set to ioemu in the guest configuration file (vm.cfg), the network device(s) may fail. The Windows Device Manager displays an error code 10 and an exclamation point (!) to show the network driver cannot be started.
This is caused bythe network type being set incorrectly in the guest configuration file.
The network card type can be set three ways:
■type=ioemu: Network card is available in QEMU mode only.
■type=netfront: Network card is available in paravirtualized mode.
■No type entry: Network card is available in both QEMU and paravirtualized
modes.
Workaround:
The issue is only applicable to Oracle VM Server 2.1.5 and does not apply to Oracle VM Server 2.2 or later.
If this issue occurs, change the network type from ioemu to netfront in the guest configuration file. Alternatively, delete the network type entry. You can make this change using Oracle VM Manager, or manually. To change the configuration manually:
1.Shut down the guest.
2.Edit the guest configuration file (vm.cfg) and change the type=ioemu entry to type=netfront, or delete the entry.
3.Restart the guest.
The network driver is started.
