Hello,
Hi Shen,
Hi Jason,
Try:
vif = [ 'backend=netbackend,bridge=dmz,type=vif' ]
This will give "test" just a PV nic (and not an emulated nic).
yes, thank you thats it!
Though to be fair, i did cross post on xen-users because i got
impatient. I tried to post here and didnt get activated on xen-devel but
also did not get any feedback from the maillinglist server about my
initial post. So i signed up for xen-users.
Then i found a solution but didnt understand it and posted my findings
their.
/var/log/xen/qemu-dm-test.log probably reports an error about bridge
dmz not existing.
It does report about missing tun interface on dom0, but i missed to look
at the log-files completely. Interesting the tun interface is not
necessary on netbackend. But i think it would be, if i have to use the
emulated type, maybe i need it later.
qemu runs in dom0, but your bridge "dmz" is in the driver domain,
"netbackend". By using type=vif, xl skips creating the emulated nic
with qemu. I think `xl network-attach` uses type=vif by default,
which also avoids the emulated nic issue.
That's the thing, i did see that the type=vif does something different
in the documentation but i did not understand what the differences are.
So because i now know something more. It makes sense and thanks for the
clarification.
Regards,
Jason
