Hi,

I encounter a problem that the eth can't be up in the VM by using VT-d.
I boot the VM using "virsh create vt_d.xml".
The VM could recongize the NIC which was assigned .then I do in VM as follows:
#cat /sys/class/net/eth0/operstate
down
#ifconfig eth0 up
#cat /sys/class/net/eth0/operstate
down
#ficonfig eth 10.100.0.5
#cat /sys/class/net/eth0/operstate
down
more system information is attached.(uname 、ifconfig 、lspci、cmdline...)

I can't figure out the reason why the eth is still down? can anyone help me ?

best regards,
qinguan
