[Qemu-devel] [Bug 1791680] [NEW] network bridge does not work

[Jan Marti]

Public bug reported:

hi there

the network bridge does not seem to work described as here:
https://en.wikibooks.org/wiki/QEMU/Networking

When i add that parameters in a 192.168.80.x subnet, my emulated
raspbian ARM gets the IP 10.0.2.15.... While all other computers get
192.168.80.x

The command i use is:


qemu-system-arm.exe -M versatilepb -cpu arm1176 -hda 2018-09-03_stretch_inkl_phalcon.img -kernel kernel-qemu-4.4.34-jessie -m 192 -append "root=/dev/sda2 panic=1 rootfstype=ext4 rw" -no-reboot -net nic -net user -device e1000,mac=52:54:00:12:34:56 &


Does not build up a network bridge to 192.168.80.x...

The host system i use is win10 x64 v1803

Best regards,
Jan

10.0.2.15 is neither a ip in our dhcp range nor an apipa address -
strange

Yes, looks like nat - 10.10.2.15 is not pingable from 192.168.80.x but
vice versa...

but wqhat they write here is not nat: "If no network options are
specified, QEMU will default to emulating a single Intel e1000 PCI card
with a user-mode network stack that bridges to the host's network. The
following three command lines are equivalent:"

And i think my params are right?

...  -net nic -net user -device e1000,mac=52:54:00:12:34:56 &

[Thomas Huth]

That comment about e1000 is only true for qemu-system-i386. For ARM
machines, there are other default NICs. You should also not mix "-net"
and "-device", see https://www.qemu.org/2018/05/31/nic-parameter/ for
some details. And concerning NAT, yes the "user" backend is using NAT,
see
https://wiki.qemu.org/Documentation/Networking#User_Networking_.28SLIRP.29
for details about that.

OK thx.

"The -device option can only be used for pluggable NICs. Boards (e.g.
embedded boards) which feature an on-board NIC cannot be configured with
-device yet, so -net nic,netdev=<id> must be used here instead."
