e1000 mac troubles

Hi all,

I’m trying to emulate e1000, for gigabit connection, on KVM88. I’m using the following net parameters:

-net nic,macaddr=52:53:54:55:56:57,model=e1000 -net tap,name=tap0,ifname=tap0,script=no,downscript=no

afterwards I run:

brctl addbr br0
brctl addif br0 eth0
brctl addif br0 tap0

The problem: On windows 2003 server the *e1000 *NIC appears ok, but just doesn’t get the mac addr that is configured and also does not comunicate with the host, only the host, via br0.

When I run the same parameters, but model=rtl8139 everything goes very well: RTL8139 gets the mac address I configured by macaddr parameter and comunicate with the host and all network via br0

Any ideas?

Thank you in advance.
Gabriel.
