Here MMIO size of your device is 0x20 Bytes. The commit fb48c7c858cc612e3e1cb011c534075ac5de553d in kvm userspace should fix it. Was it included in your userspace? The commit changes rom bios, you can use "make bios", and "make install" to make it take effect. And I think replacing "-net nic,macaddr=52:54:00:58:08:03 -net tap,script=/etc/qemu-ifup" with "-net none" will also work for you.

We can see if its mmio is page aligned or not. Can you check if commit fb48c7c858cc612e3e1cb011c534075ac5de553d was included in your kvm-userspace? > root@xp8main3:/etc/kvm# uname -a > Linux xp8main3 2.6.29-rc6-xp8no7 #1 SMP Thu Feb 26 12:27:17 CET 2009 > x86_64 GNU/Linux > > > greets freisei -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
