On OpenSolaris 2009.06 I created a flow, half a dozen VNICs, and I set some properties, and everything was working, then I rebooted my system and everything disappeared from show-vnic, show-flow, and show-prop. When I tried to re-create the objects, dladm said they already existed. While I could not see the objects, I could delete them. Example: # dladm s...

How do I create a vnic that represents the factory assigned MAC address of my physical nic? The bge device in my system (x2100) appears to support 4 MAC addresses. The driver reserves the first as the ''primary/default'' address and allows manipulation of the other three via the MAC_CAPAB_MULTIADDRESS i...

Using OpenSolaris 2008.11 build 110. Created vnic''s and etherstub''s and they are displayed using dladm show-links but when the server is rebooted a ''dladm show-link'' is empty although the vnic and etherstub devices are still there and function properly. That is a real inconvenience, so why do the no longer show...

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: open("/devices/pseudo/vnic at 0:ctl", O_RDWR) Err#2...

...rfaces. This has not been a problem with the e1000 driver. This particular server is a generic x86 system with dual onboard bge. We are running OpenSolaris b113. Frequency Always Regression No Steps to Reproduce Create aggr0 consisting of one or more bge interfaces. Create a global0 vnic on top of aggr0. Plumb global0 and configure it on the network. Ping the address for global0. Expected Result No duplicate packets generated by the host. Actual Result Duplicate packets sent by the host. Workaround Do not use aggregate datalinks on bge, or choose different hardware...

...priority. The kernel provides priority range between MINCLSYSPRI (60) and MAXCLSYSPRI (100) for threads in the system class. We define three levels of priority - low, medium and high within the range MINCLSYSPRI and MAXCLSYSPRI. The priority level can be assigned when creating a virtual link (say VNIC) or can be modified for an existing link using dladm(1m). The priority level is a property of the link. Setting a priority essentially means setting priorities for the following elements associated with a MAC client[1], specifically: Soft Ring Set(s), SRS, (Rx and Tx):...

Hi, Is there any way to add VNIC to the domU? # virsh attach-interface mydomU network myvnic1 # libvir: XML error : missing source information for device myvnic1 It''s SXCE105. -- Regards, Piotr Jasiukajtis | estibi | SCA OS0072 http://estseg.blogspot.com

No, they would not be in promiscuous mode. The VNIC''s would be in promiscuous mode only if a DLPI application enables it using dlpi_promiscon() with DL_PROMISC_PHYS flag. So, we do not register VNIC''s promiscuous c...

Folks, I just posted an updated Crossbow virtualization architecture document. The new revision is available at: http://opensolaris.org/os/project/crossbow/Docs/crossbow-virt.pdf The main changes are the addition of support for multiple MAC addresses per client, and an explicit separation between consolidation private and project private MAC API entry points. See in particular the

Hi, all I want to get some information of How xVM is integrated with Crossbow project. Do some buddies have those documents or blogs? Thanks --luke

...Socket Socket Message Elapsed Size Size Size Time Throughput bytes bytes bytes secs. 10^6bits/sec 49152 16384 16384 10.01 87.73 client% Likewise, if the host connects to itself uning VNICs built on physical links or etherstubs the maxbw setting seems to have no effect. Only when I cross zones do I see it working. Thanks for any help, swagman

...in my current project to support multiple co-located zones on the same VLAN. Our current deployment OS is Solaris 10 Update 4. I''d like to use exclusive IP zones, but I gather the only way to currently have multiple exclusive zones with interfaces on the same VLAN is through the use of VNICs. From my initial look at S10u4, it seems VNIC support been not yet been integrated into that release. Is this correct? Thanks - Andres

...GLDv3 processing, that won''t be available. I don''t see a solution for this except to document this restriction. 2. VLAN kstats won''t work. If we enable UV fastpath over VLANs, packets would go directly between the lower VLAN stream and the IP stream over softmac, the VNIC (vlan) kstats won''t be updated. This could be work around by changing vnic_m_stat() function, to add up the legacy VLAN kstat (e.g., kstat of ce1000). 3. Performance of VLAN is not optimal In the current Crossbow code, once a VNIC (vlan) is created, the underlying mac is started (by...

...virtual network cards (e1000), all on the same flat network/subnet. It started life just 2 days ago with a clean install of snv_95, and I LUed to 105 yesterday. To rule out any sharing issue, the first nic (e1000g0) is used only for the global zone. The second nic is used only by crossbow, for the vnic "zonevnic0", which is bound to e1000g1. sparse-template is the zone that I''ve been trying to get to work using a dedicated IP instance using the vnic zonevnic0. Using snoop in the zone, (or in the global zone, with "-d zonevnic0") I can see broadcast/unicast traffic go...

1 simple question about network statistics for vnics: We noticed that the statistics for vnics (used by Virtualbox guests) are not there. When the nics are plumped in the host OS, we do see them showing up, but all all records are 0. Can someone tell me how to get the correct network info via snmp on the Vbox Host?? Thanks in advance. IF-MIB::if...

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 e100...

...6601421 dladm set-linkprop should support multiple -p options along with some related linkprop fixes, but when I looked into dladm.c, was surprised to find that "dladm_parse_props()" is called from do_create_aggr and do_create_vlan in addition to the expected (by me, at least) do_create_vnic *linkprop functions. What happened here? Why do we pass in property lists for aggr and vlan creation? Even more confusing is the fact that the dladm usage string (emitted when one types dladm with no args) does not have any hint of the -p option for vlans and aggrs. At least that, needs to be fi...

Hi All, I have bfu''ed to net-virt_xb-21_snv_81_021308. The dladm command on my machine does not have create-etherstub option. Please let me know what could be the issue. Thanks Khushal
