I think, as workaround, we can simply write the state to the config file

net0: ....,linkstate=on|off


and use set_link to enable|disable it, and update the config.

at vm start, we can simply call qmp set_link if the link need to be set off.

I want to make a new feature where you can control the nic link. 

for the gui we need to show the status.

No, links status is not implemented. 

Maybe can we make a qemu patch for this ? 

(They are some example in net.c , qmp_set_link (), to get the current status link.) 

Why do you need it exactly ?

Hi Alexandre, 

thanks for your answer. 
When i use hmp "info network" i get only informations about the network settings. 
nothing about the status. 

>qm> info network 
>net0: index=0,type=nic,model=virtio-net-pci,macaddr=e2:cf:7e:db:6f:e0 
>net0: index=0,type=tap,ifname=tap100i0,script=/var/lib/qemu-server/pve-bridge,downscript= >/var/lib/qemu-server/pve-bridgedown 

Is there something I have been missed?

Hi, 

>>is there a way to get the Nic Link status from Qemu? 

I have check the qemu code (net/net.c), I don't think it's implemented. 

we can only have info through hmp "info network", qmp not implemented. 

and we can only set the status with qmp "set_link"
