Hello,

I have a windows 2000 working over Xen for a year. After I reboot the Host
(SLES 10 SP1), when I start VM windows 2000 I realize that the link speed had
change. In the past the link was 1000Mb/s and now I don't have this option, the
top link speed is 100Mb/s Full Duplex.

The 4 network interfaces in Dom0 are all 1000Mb/s and the server is a DELL
2970.

In Dom0 the result of ethtool for the physical interfaces added to the bridge
of the guest windows 2000 is below:

        Supported ports: [ TP ]
        Supported link modes:   10baseT/Half 10baseT/Full 
                                100baseT/Half 100baseT/Full 
                                1000baseT/Full 
        Supports auto-negotiation: Yes
        Advertised link modes:  10baseT/Half 10baseT/Full 
                                100baseT/Half 100baseT/Full 
                                1000baseT/Full 
        Advertised auto-negotiation: Yes
        Speed: 1000Mb/s
        Duplex: Full
        Port: Twisted Pair
        PHYAD: 1
        Transceiver: internal
        Auto-negotiation: on
        Supports Wake-on: g
        Wake-on: d
        Link detected: yes
Could you help me?

Tanks
