Hi, all:
my environment is qemu-kvm-6.0.0, 4.18.0-240, libvirt 7.4.0. vm is configured like this queues='4' rx_queue_size='1024' tx_queue_size='1024'.
inside vm i can not change nic's ring size.
changing tx leads to error 'Cannot set device ring parameters: Operation not supported'.
changing rx leads to error 'rx unmodified, ignoring. no ring parameters changed, aborting'
how to make it work and confirm what current value is?
thanks
