Hi the Crossbow team, I am testing my UV fastpath bits and I found several issues that need your suggestion: 1. dladm show-usage won''t work if UV fastpath is enabled. Since the link usage data are collected based on the statistics of the mac_client_impl_t, and UV fastpath skips the GLDv3 processing, that won''t be available. I don''t see a solution for this except

As requested by several people, an Overview document has been posted at http://blogs.sun.com/sunay The reference section also contains a pointer to the slides that will be used for tonights presentation. See you all there. Cheers, Sunay -------- Original Message -------- Subject: [osol-discuss] SVOSUG - This Thurs, August 24, Sunay Tripathi presents Crossbow 7:30pm SCA03 Date: Mon, 21 Aug

Crossbow team, The following is of interest to the Crossbow project. Since a large chunk of these changes also exist in the Crossbow gate, the delivery of this wad will result in fewer lines of changes for Crossbow''s delivery. If someone on Crossbow could participate in this review, that would be a bonus (Eric Cheng made original changes in the Crossbow gate at some point last year).

I have installed on a VirtualBox vm the crossbow ISO Now I''m trying to create the network map described in the "getting started" pdf I have this situation: On global zone, I have the real NIC: e1000g0 with ip 10.0.2.15 (VirtualBox NAT this IP, I can get web access with it) I have created an etherstub (etherstub n?2) with 2 vnics (vnic5 and vnic6), I''ve plumbed

(Bcc''ed to networking discuss). Hi All, Have enclosed man page draft for dlstat(1M) herewith. This is part of the effort to gain better visibility into network traffic in light of crossbow features like virtual NICs, interrupt vs. polling modes etc. This in turn would greatly assist network performance analysis. It is also aimed at segregating link/flow configuration from

Hi Everyone - Here is a draft of the first of two "pages" that I will submit to Wikipedia. The first page is a general network virtualization page. From this page, I will contribute a subpage on the Crossbow projects. These two articles are the first of a number of online articles on Crossbow that I''ll be creating on behalf of the Crossbow iteam. The article uses

Hi everyone, I''m Ezequiel from Buenos Aires. I''m new in this list, so please forgive me if my questions are not the correct one''s fro this alias. I''m working as a campus ambassador in Sun, while finishing my engineer degree, creating communities around opensolaris in Argentina. I discovered this project, and this group, looking for something that I could

Hi, I was trying to download the Crossbow ISO from : http://opensolaris.org/os/project/crossbow/snapshots/ under "Crossbow Beta iso images June 6 2008" and it failed. Does anyone know of a link which is working ? Thanks for any pointers ! Regards, Sanjeev.

I just BFU''ed up to B61 and started to play with IP Instances. I''m having trouble making my zone happy: root at aeon zones$ zoneadm -z testing1 boot zoneadm: zone ''testing1'': WARNING: unable to hold network interface ''skge0''.: Invalid argument root at aeon zones$ dladm show-dev nge0 link: up speed: 100Mb duplex: full

Hi, I maintain a driver for a 10GbE nic which supports multiple hardware tx/rx rings. We can steer rx packets into rings using the "standard" NDIS6 Toeplitz hashing on TCP port numbers, IP addresses, etc. We can also steer packets based on MAC address. Would this NIC be considered to be capable of supporting crossbow? Also, can crossbow do things like steer outgoing packets to the

Hello, I've port installed 3.3.7 samba onto the box and was trying to start samba server through '/usr/local/etc/rc.d/samba' with no success (server wouldn't start at all). I've tried running '/usr/local/bin/smdb -D' and server started for few moments before it died. Below are configuration files and log dump with the dump error. What am I doing wrong? [root at

Howdy, I just finished reading through the Crossbow presentation: http://blogs.sun.com/sunay/resource/crossbow.pdf And have one question. If you create a virtual NIC with dladm: $ dladm create-vnic -d bge0 -m 0:1:2:3:4:5 -b 10000 1 Can you then add vnic1 directly to the zone? e.g.: zonecfg -z zone1 zonecfg:zone1> create zonecfg:zone1> set zonepath=/zones/zone1 zonecfg:zone1> add net

Hey ..This looks very much like the user-mode linux i used to work on. not gone thru the Xen specs but what crossbow looks like is solaris version of UML[user-mode linux] . last time i was almost killed testing free/swan on a virtual testbed using UML. gosh... matching the root filesystem version with the kernel was the biggest fight...lately had to build my own with mkrootfs :) ... best view of

Howdy, I just installed the crossbow snapshot from opensolaris.org, and bumped into an issue when attempting to create a virtual nic: $ dladm create-vnic -i 192.168.1.101 -d ni0 2 dladm: VNIC creation failed: No such file or directory (unknown diagnostic) When I truss the process, it looks like it''s failing when attempting to open the vnic pseudo-device: 100878/1:

Recently I found that the mac_srs_rx_poll_ring thread may never stop in kernel, please see the following mpstat, cpu 2 is in 100% kernel usage, but no syscalls and no interrupts.

Ok, I''m hoping this is a fairly trivial issue, and I''m missing something. I''m trying to use Solaris zones (Nevada Build 117) to act as a DMZ and a router, using exclusive IPs, VNICs (from Crossbow), and connecting to the internet (static IP from my ISP). I''ve got the DMZ working - that zone sees the internet, can do name lookups, ftp, telnet, ssh, etc etc etc.

The following is mainly a capture of parts of multiple off-line discussions within members of the Crossbow team (Gopi, Thiru, Roamer, May-Lin, Thirumailai, Nitin, KB, ...), I thought I''d open it up to other participants. Crossbow''s core scheduling involves switching a NIC (or individual Rx rings on the NIC) to polling mode. The receive interrupt will become not only rarer,

I''ve been thinking about hardware that has multiple transmit rings ("tx resources"). We really should have a way to expose this up to the stack. And ideally, the stack should guarantee that a given flow will always be sent down using the same hardware tx resource. I''ve heard that crossbow will deliver this, but I can''t find evidence of it in the crossbow

Hi All, >From the design documents, I see there is an option "DLADM_VNIC_OPT_NODUPCHECK" for checking if the vnic MAC is unique on the same physical NIC. I have a question here. Does crossbow check if the MAC address is unique on the same subnet? E.g, create a vnic on hostA with hostB''s MAC address. Thanks, Karol

Hi, >From what I have read, the create-vnic feature in dladm is only available within the context of crossbow...? Specifically, what I am wondering is whether it is at all possible to successfully install crossbow on top of Sun''s "Standard/sunsolve supported" Solaris 10/08 rather than OpenSolaris, per. Se.... Is this at all feasible? Many thanks in advance.. Best
