Hi,
i today updated to latest qemu snapshot from git. Unforunately I stumbled over
the following problem:
Case 1) -net tap before -net nic
cmdline: /usr/local/bin/qemu-system-x86_64 -net
tap,vlan=711,ifname=tap3,script=no -net
nic,vlan=711,model=e1000,macaddr=52:54:00:ff:00:02 -net
tap,vlan=712,ifname=tap4,script=no -net
nic,vlan=712,model=e1000,macaddr=52:54:00:ff:00:03 -hda /dev/sdb -m 1024 -smp 2
-localtime -usb
- -usbdevice tablet -monitor tcp:0:4010,server,nowait -vnc :10 -name XXX -boot
order=c,menu=on
- -pidfile /var/run/qemu/vm-3.pid
Everything works as expected.
Case 2) -net tap after -net nic
cmdline: /usr/local/bin/qemu-system-x86_64 -net
nic,vlan=711,model=e1000,macaddr=52:54:00:ff:00:02
- -net tap,vlan=711,ifname=tap3,script=no -net
nic,vlan=712,model=e1000,macaddr=52:54:00:ff:00:03 -net
tap,vlan=712,ifname=tap4,script=no -hda /dev/sdb -m 1024 -smp 2 -localtime -usb
-usbdevice tablet
- -monitor tcp:0:4010,server,nowait -vnc :10 -name XXX -boot order=c,menu=on
-pidfile
/var/run/qemu/vm-3.pid
I get the following warning:
Warning: vlan 712 is not connected to host network
In the qemu monitor I see, that vlan712 does not contain the tap interface.
However, the tap4
interface is created on the host. vlan711 is working as expected.
I suspect that is has sth todo with the migration to QemuOpts as an earlier
checkout without
QemuOpts works well.
Can someone who is more familiar with the QemuOpts implementation please look
at this.
Thanks,
Peter
