Hi,<br><br>I encounter a problem that the eth can't be up in the VM by using VT-d.<br>I boot the VM using "virsh create vt_d.xml".<br>The VM could recongize the NIC which was assigned .then I do in VM as follows:<br>
#cat /sys/class/net/eth0/operstate<br>down<br>#ifconfig eth0 up<br>#cat /sys/class/net/eth0/operstate<br>down<br>#ficonfig eth 10.100.0.5<br>#cat /sys/class/net/eth0/operstate<br>down<br>more system information is attached.(uname ¡¢ifconfig ¡¢lspci¡¢cmdline...)<br>
<br>I can't figure out the reason why the eth is still down? can anyone help me ?<br><br>best regards,<br>qinguan<br><br><br><br>vt_d.xml:<br><domain type='kvm'><br>    <name>test</name><br>    <description>just test using sriov!</description><br>
