I tried vhost-user mode, and during init of ./vhost-switch it fails with PMD: eth_ixgbe_dev_init(): port 0 vendorID=0x8086 deviceID=0x1528 pf queue num: 0, configured vmdq pool num: 64, each vmdq pool has 2 queues EAL: Error - exiting with code: 1 Cause: Cannot initialize network ports
it's failing in port_init function, and it seems from http://dpdk.org/doc/guides-1.8/rel_notes/resolved_issues.html this has to with ixgbe checking for eeprom pba parameters. is that correct, coz rebuilding ixgbe 4.3.13 by disabling those lines dint help either? i tried enabling configure CONFIG_RTE_LIBRTE_ETHDEV_DEBUG=y but still i don't see the log messages under /var/log nor on stdout? just to keep ball rolling i'd like to see at least kni compiling and working. FYI, i am using X540-AT2 cheers On Mon, Apr 11, 2016 at 10:09 AM, chintu hetam <rometoroam at gmail.com> wrote: > Thanks Xie. > > I am trying to test FreeBSD-9.3-virtio as guest.
