[Qemu-devel] Networking hangs

[Christoffer Dall]

Hi.

I am experiencing problems with bridged networking to ARM guests. I have 
experimented with various kernel versions, distributions and host 
machines and I experience the problem in all cases.

When I copy files into the guest using SCP, after an undeterministic 
number of megabytes have been copied, the network crashes. At this point 
not even pings to localhost works inside the guest.

I am using v0.11.0, emulating a versatilepb board with an arm1136-r2 cpu 
and using the following parameter for networking when running the system 
emulator:

-net nic,vlan=0 -net 
tap,vlan=0,ifname=tap0,script=$(QEMUIFUP),downscript=$(QEMUIFDOWN)

QEMUIFUP:
ifconfig tap0 192.168.7.1

QEMUIFDOWN:
ifconfig tap0 down

Any help is greatly appreciated.

Best,
Christoffer Dall
