Re: [Xen-devel] More on networking hang

Just to check I understand your setup: You have a domain 0

That's correct.
When the domain chokes, do you you see any drops or errors in the
stats as reported by ifconfig?
In domain 0, ifconfig reports 0 errors, 0 dropped on eth0; 0 errors, 2
dropped on vif1.0, and 0 errors, 5 dropped on vif2.0; 0 errors, 0
dropped on xen-br0.
In domain 1, ifconfig reports 0 for errors and dropped.
For some reason I can't get a console onto the other domain right now,
but I suspect it will report the same thing as domain 1.
It would be good to enable the debugging printf's in both the
netfront and netback drivers.
Can do.
Can you repeat this with a single non-0 domain? Can you repeat it more
easily by generating a background network load in dom0?
Can try these.
BTW: Have you got CONNECTION_TRACKING compiled into the dom0
kernel? This seems to cripple Linux performance, hence it was
recently made a module in our config.
We are using only default options.
