Hi all, Anyone knows if exists some plan to support Intel 10Gbps nics like ?for example 82575, 82576, 82580 or 82598EB Ethernet controllers under KVM for virtual guest like it does with e1000 driver? Regards, C. L. Martinez

Hello, I''m using a server with 10Gbps network interfaces and 4 CPUs, running several domUs. The problem is that in this setup, with high network load, dom0 turns out to be the bottleneck, using only a single CPU which is saturated and 100%. So the network speed is bounded to much less than 10Gbps. How could I make dom0 use more CPUs in...

Greetings, I am located in India. Any experience or suggestions for building blocks using copper preferably (and not fiber SAN)? Enclosures, Technologies (iscsi etc). Many US companies are very picky about export regulations for such humongous data appetites. The application is mainly A/V or vfx file handling. -- Regards, Rajagopal

...7.13. The mac os client is running Darwin 18.7.0 (have also tested and confirmed behavior on Mojave 10.14.6) and writing to SSD, and I confirmed that comparable FS operations locally do not incur the performance penalty, only from SMB to disk. iperf gives the connection speed its full line rate of 10gbps, and disk read performance of the smb server is >10gbps. I've tested the same operations from linux <-> linux via the smb share, but no performance drop off was seen. Further, copying large files back and forth also saw no problem. I'm wondering if anyone might have any knowledge...

If we add a default get_settings that can be used by virtual devices in ethtool that returns 10Gbps with the settings set like veth does sounds good to me. What do you think ? In fact they all set the same settings (apart from speed) so we can consolid...

We have a 10Gbps connection to our server so I need to be able to create VMs using the faster e1000 nics instead of the default Realtek 100Mbps ones but I''m not sure how to go about it. Is there a walkthrough or "howto" or can someone point me at some simple instructions? I''m using xen-3...

...acing a 80TB SAN system based on StorNext with a Isilon system with 10G network connections. If there was a way to create a Linux (Centos) 100TB ? 500TB or larger clustered file system with the nodes connected via infiniband that was easily manageable with throughput that can support multiple 10Gbps Ethernet connections I would be very interested. And once more thanks for the fast response. Mike

Hi, Is anyone using GlusterFS on Ubuntu in production? Specifically, I'm looking at using the NFS portion of it over a bonded interface. I believe I'll get better speed than user the gluster client across a single interface. Setup: 3 servers running KVM (about 24 VM's) 2 NAS boxes running Ubuntu (13.04 and 13.10) Since Gluster NFS does server side replication, I'll put

...missing in this emulation: " "unknown longword write"'' failed. The domain crashes. I suspect this occurs because I am trying to build the domain with a vif where model=i82559er. Changing the model to e1000 does build the domain. I would prefer to have the ability to use 10Gbps because my physical nic is also a 10Gbps nic: 02:00.0 Ethernet controller: Intel Corporation 82599EB 10-Gigabit SFI/SFP+ Network Connection (rev 01) For further contact please be aware I am not receiving xen-devel emails, so please include me in CC''s when more info is required.

...onflicted need: the NFS is needed to resolve the mmap issue (and hopefully do some speed up that the users see) but the real high-speed need is possibly through pNFS clients to NFS-Ganesha but those connections will be over infinniband so only TCP and no RDMA. That drops my raw speed from 40Gbps to 10Gbps (connectx-2 gear). I can run gnfs on RDMA (40Gbps!) but no NFSv4.1 for pNFS AND a manual mess setting up HA for connections. The last connection fun is not all clients connect over infinniband so I do have standard ethernet ports as well (40Gbps feeding multiple switches for 10Gbps and 1Gbps). --...

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
