hi guys I wonder if any of you might be using SFN6122F-R7 SFP+ (SFC9000, same firmware everywhere, Centos 7.5 too. I'm trying poor man's setup to get the servers onto 10GbE network. Setup is such that three Dell R815 are connected to each other, each has one Solarflare(SFP ports) and each Solarflare is set as net-team(both ports on a card are net-team device) with runner in broadcast mode. And it all seems to work, they ping each other, iperf okey. The problem, big problem is that when traffic start to flow between all three servers simultaneously, with rsync...

...m getting quite confused with all the different terms different companies use to describe NIC''s virtualization support. Any ideas what the differences are between these brands? I am trying to sort a comparison table but will need some help: Feature Intel ET Series Mellanox ConnectX Solarflare Receive Queues 64 32 ? Transmit Queues 32 ? ? PCI-E Version 2 2 1 Direct IO No No Linux PV Only Mac/Vlan per port ? 128 4096 IOAT and MSI-X Yes Yes Yes Does the Solarflare chip support multi-queue as well as direct IO? Any other features I should be looking at? Thank...

...RPS should own this structure. It's just that there are currently no per-RX-queue attributes other than those defined by RPS. By the way, CONFIG_RPS is equivalent to CONFIG_SMP so will likely be enabled already in most places where virtio_net is used.

hi, I want to know some details about this network accelerated modules. 1)what''s the main purpose of this plugin module? 2)any requirement for harware nic? or other hardware platform? 3)I''ve not found the code in Xen3.1 code set. so was it added to xen source code yet? Thanks in advance _______________________________________________ Xen-devel mailing list

I''m having problems starting more than three domains. It sometimes works fine, but more often than not the 4th domain''s root block device times out and so the domU kernel panics as there''s no /dev/root: XENBUS: Timeout connecting to device: device/vbd/2057 (state 6) XENBUS: Timeout connecting to device: device/vif/0 (state 6) XENBUS: Timeout connecting to device:

When vlan device is configured on top of the brige, it does not support any offload capabilities because the bridge device does not initiliaze vlan_fatures. Set vlan_fatures to be equivalent to hw_fatures.
