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

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.

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

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

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

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. CPU minf mjf xcal intr ithr csw icsw migr smtx srw syscl usr sys wt idl 0 0 0 0 300 100 0 0 1 0 0 0 0 0 0 100 1 14 0 0 134 68 134 1

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, >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

(networking-discuss Bcc''ed) Good morning, The Crossbow team would like to invite you to participate in the project''s third and last phase of code review. The third phase of the review starts today, and will last for two weeks. It covers the following parts of the code: VLANs Link Aggregations Xen mac_datapath_setup All drivers

In current Crossbow''s implementation, vlan tag seems to be unconditionally retained for promisc mode listener even when MAC_OPEN_FLAGS_TAG_DISABLE is not specified. I saw comments in mac_rx_deliver() saying that this is deliberately designed like this. I''m wondering why we design it like this (choose not to respect MAC_OPEN_FLAGS_TAG_DISABLE flag for promisc mode listener)? Or

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.

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

So, just to play with vnics with 106, I have... e1000g2 plumb''d with 192.168.85.10 vnic0 is created on top of e1000g2 with 192.168.85.22 I snoop on e1000g2 to see the traffic. I ping 192.168.85.22 and it works. I stop the snoop on e1000g2. I ping 192.168.85.22 and it doesn''t work. I start the snoop on e1000g2. I ping 192.168.85.22 and ping works. Is this a new feature with

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,

Team, We are trying to install Crossbow on VirtualBox. Siva first tried it on Linux and reported it in Hyderabad Open Solaris User Group alias. http://opensolaris.org/os/project/hosug/ Today both of us tried it on VirtualBox running on OpenSolaris. Both attempts have the same results. a. Selecting Solaris Developer Express during boot process exits the installation. See this picture:

Actually, it is not a list.. but just something that''ll be very useful to me in my business. If crossbow/virtual interfaces can provide a flow that can capture bandwidth usage over a period of time (including 95 percentile), that''ll be great! Is this possible? -- This message posted from opensolaris.org

In crossbow, each mac_srs has a kernel thread called "mac_rx_srs_poll_ring" to poll the hardware and crossbow will wakeup this thread to poll packets from the hardware automatically. Does crossbow provide any method to disable the polling mechanism, for example disabling the this kernel thread?

Hi. After running with the crossbow bits for a while, I discovered that the network management port on my T1000 wasn''t working properly (no link light). When logging in on the serial management port and running "resetsc", I got this: --->8--- ALOM POST 1.0 Dual Port Memory Test, PASSED. TTY External - Internal Loopback Test TTY External - Internal Loopback Test, PASSED.
