OK so the number of queues is 17. You probably don't need that many
queues.
Set module parameter "xenvif_max_queues" of netback to something like 4
should work around the problem for you.
Hello
I tried to set it to 4 in /etc/modprobe.d/xen_netback.conf
rmmod xen_netback
modprobe -v xen_netback
insmod
/lib/modules/3.16.0-4-amd64/kernel/drivers/net/xen-netback/xen-netback.ko
xenvif_max_queues=4
But it is still the same issue..
Is xenvif_max_queues supported in Linux kernel 3.16?
modinfo -p xen_netback
separate_tx_rx_irq: (bool)
rx_drain_timeout_msecs: (uint)
rx_stall_timeout_msecs: (uint)
max_queues:Maximum number of queues per virtual interface (uint)
Oh, right, the parameter name should be "max_queues".
Sorry about that!
Wei.
It's still the same issue:
modprobe -v xen_netback
insmod
/lib/modules/3.16.0-4-amd64/kernel/drivers/net/xen-netback/xen-netback.ko max_queues=4
But what could be reason for this?
Could it be problems with one of the CPUS? since if I boot dom0 with
just 14 cpu cores then it works....
