• Install the components of the network on vSphere host via API NSX virtualization

  I want to install the components of the network on vSphere host via API NSX virtualization, can anyone help me?

  Hello

  What SDK NSX are you referring?

  I can confirm, that the next REST call will work to prepare the cluster hosts.

  POSTER https://nsx-mgr-ip/api/2.0/nwfabric/configure

  field-c11

  You will receive the in the http response.

  The job status can be asked here:

  https://NSX-Mgr-IP/api/2.0/services/taskservice/job/

  field - c11-> MoRef of the cluster you want to prepare. I guess you know how to get the MoRef in a Cluster.

  Don't forget basic authentication and the Content-Type: application / xml header

  I hope this helps

• Need help to understand the network of vSphere environment

  Hello

  I need your help in understanding the network environment in vSphere. Please see the diagram and the text below:

  

  NIC #1 - Management Port (access from client vsphere, vCenter server)

  NIC #2 - Port of VMkernal (for iSCSI, vMotion, etc.)

  NIC #3 -?

  #4 – CARTE NETWORK INTERFACE?

  Q1 how allow external users to access services over the ESX host? (for example, IIS, FTP, Exchange, NFS)

  Q2, what will be the role of the other two network cards? Is it connected to the physical switch?

  * Ask you all to please help me by sharing your knowledge / experience on the network portion, you have made in your environment as NIC how, what to do with that. *

  I really need to understand the networking of concepts in vSphere, hope that your help!

  
  

  Best regards: Yash

  With an additional NIC with 2 port a general configuration might look like this:

  vSwitch0 - vmnic0, vmnic1 (connected to different physical switches)

  Network VMkernel management

  VMotion VMkernel network (own IP network, own VLAN)

  Better if they is configured as active / standby.

  vSwitch1 - vmnic2, vmnic3 (connected to different physical switches)

  Trade VM

  vSwitch2 - vmnic4, vmnic5 (connected to different physical switches)

  VMkernel iSCSI (own IP network, own VLAN)

  Ideal if it is added to the component Multipath iSCSI, which is quite easy to vSphere 5.

• New here - problem with the network on vSphere, ESXi

  Not sure if this is the right place to post this, please direct me properly if it is not.

  I use an eval of vSphere ESXi on a HP workstation. I built 2 Windows 2 k 8 VM 32 bits on the first data store. They can ping and DNS seems to be resolved, but they cannot access Internet/WWW.

  I accepted the default when installing ESXi and vSphere, so the configuration of the network is all that is by default (using the switch vNetwork, I think?)

  The 2 servers are on a different area of our production area. For this case, we'll call it consigment and Lab.com. "PDC" server is the domain controller, 'Exch8' is the exchange server in the lab. Exch8 has its pointed DNS, PDC and PDC has its DNS indicated on our DNS server in the environment of consigment. They are all on the same subnet 172.1.1.x

  I can ping PDC and Exch8 of my workstation (which is in consigment) by IP, but not name (pdc or pdc.lab.com, or work).

  Can someone at - it facilitate troubleshooting?

  Thank you

  OK finally try this out... It must be something to deal with the configuraiton of windows rather than dealing with VMware.I belive

  1. on the server you can navigate on the internet - see the proxy setting.

  See how proxy setting - open internet explore - switch to the option internet tool - connection tab click lan setting and get the configuraiton of proxy and put it in the PDC. Lab.com server and see if it works...

  2. also if you have installed antivirus tools on the server that you are not able to browse internet but able to ping... Uninstall AV and try...

• reconfiguration of network management vSphere

  Hi all

  I have 5 guests VMware ESXi 4.1 + vCenter.

  Now I intend to expand the DC, but current subnet for management and vmotion is too small.

  All current servers use cSwitch0 for all (vmotion, management, etc.)

  I have instaled the new EXS, in different subnet host and want to add to the HA cluster.

  vSwitch0 - management

  vSwitch1 - only vmotion

  I got the error:

  Host vth-01 has additional networks not used by other hosts for HA communication: 192.168.21.194. Consider using HA advanced option
  das.allowNetwork to control the use of network

  Host vth-01 does not have the networks used by other hosts for HA communication: 192.168.17.244. Consider using HA advanced option das.
  allowNetwork to control the use of network

  If in HA advanced options I put "das. AllowVmotionNetworks True"and "das. Console Service AllowNetworks0"

  I always get the error:

  The host vth-01 (new host ESXi) currently has no network available for ha comunication. Networks are currently used by HA: Managmetn Console

  What should I have to do, to put this host to the HA cluster?

  Thank you.

  VT - 02 (former ESXi host) the host currently has no available networks forHA comunication. Networks are currently used by HA: Managment Console

  Hmm

  so you have ESXi, I think that rather than use the Service Console (which is located in ESX) you should try with the network management setting (simply you have not named network configuration Service Console port group)

  das.allowNetwork Management Network

  PS advance option called das.allowNetwork nos das.allowNetwork

  See you soon

• design of network of vSphere - thoughts?

  Hi all

  Looking for some advice/confirmation on a generation, that I am putting together

  Material Blade C3000, 4 switches Passhru

  x 2 servers BL460c G6 with 6 CARDS each.

  Design is similar to the following,

  2 NIC team for production, service on the same vSwitch0, thoughts on this console?

  1 NETWORK adapter on each host for Vmotion

  x 2 card NETWORK ISCSI SAN and SC (ISCSI are not used before just FC)

  1 NETWORK DMZ map on each host

  It work ok? Using PassThru to keep things simple and main switch patch and DMZ appearance.  No security concerns?

  Look forward to the comments.

  See you soon

  Use only 2 NIC for iSCSI... no SC.

  If you have 4 NIC free and you might consider (if possible) to use the VLAN tagging for vMotion, DMZ, management, LAN on the same vSwitch.

  Then for each group of port use the tag VLAN right and bind it on different NIC

• Best practices for the redundancy of the network in vSphere 4

  I'm running a cluster of production with 3 3850 m2 running at this time around 70 machines virtual, with more to come in the future.

  I have 6 CARDS each to use for networking.

  I'm not sure which is the best award of the NICs process.

  The redundancy for the VMKernel can I?

  Team for the Service Console NIC?

  I currently have the following:

  vswif0 Console of Service vmnic0

  vswif1 network of the VM vmnic3, 4, 5

  vswif2 VMotion vmnic1, 2 (different subnet)

  I have need of 3 NICs for the virtual machine or should I team the Service Console?

  It would be better to put a second Service Console on the Virtual Network machine's power switch, or do I have to put it on the switch of VMotion?

  My prefereence is for VMotion switch, but I'm ready to hear the recommendations of those wiser than me!

  I have 8 currently

  2 > SC (1 active, 1 standby on separate physical switches)

  3 > VMotion, FT, customer iSCSI PG (Etherchannel) MTU = 9000

  3 > VM PG VLAN (Etherchannel)

  previous to this, I had 4 I did:

  2 > SC, (2 active) VMotion, VST (vSwitch VLan Tagging)

  2 > VM (2 active) VLAN, VST (vSwitch VLan Tagging)

  Saw some problems with STP so separated back SC.

  6 as you do it sounds like a very good Setup.

  (2) SC, VMotion (active on each, Eve for each)

  (4) networking VM

  Don't forget that just them having active only effects not inbound traffic coming out unless you have all these ports in an Etherchannel configuration.  There is an example in the kB for this.  But depends on the amount of traffic all VM networks have if they network traffic a lot you could get by with less ports there.

  The SC definatally you want some kind of uplink port intelligence network as with ESX SC with HA ports check insulation network through these ports, so if this one is down which could lead to problems of isolation.  It's not like you'll do any FT? so it's something else to think about with the installation program.

• Network with vSphere 5.5 and Windows 2012 problems

  Hello

  A few weeks ago, I have updated a server to a client of 4.0 to version 5.5. There was a mistake in any way, but that's another topic...

  Did the update because we run a machine Win2012 on this subject.
  Soon, I recognized that I have trouble, access to the machine, freshly installed by RDP. Some times it works, but mostly it doesn't. It simply expires. All the other virtual machines on the host (Win2008) seem to work very well (haven't heard anything else among users).

  From another VM on the same host, I started to ping the machine of W2012:

  Ping as 172.30.50.135 ausgeführt wird mit 32 bytes of data:

  Antwort von 172.30.50.135: bytes = 32 time < 1 ms TTL = 128

  Zeituberschreitung der Anforderung.

  Antwort von 172.30.50.135: bytes = 32 time = 1ms TTL = 254

  Antwort von 172.30.50.135: bytes = 32 time = 1ms TTL = 254

  Antwort von 172.30.50.135: bytes = 32 time = 1ms TTL = 254

  Huh? A ping with TTL 128, it has expired, then all the wider with TTL 254, cannot access the machine...

  After about three minutes the TTL to 128 jumps and I am able to access the machine again.

  If I disconnect and wait a few minutes, the same thing happens again... Very strange...

  Have not tried to use an adapter E1000 instead of vmxnet3 yet, but here to warn that if possible.

  Any ideas I could try?

  Thank you
  URS

  Oh... Shame on me... What a rookie mistake... Ha ha ha...

  Well... There was a point of access that are configured with the same IP address * facepalm *. I probably did it on the first installation and always used the same wrong IP address on and on. (Don't tell my colleagues!)

• Network mapping network Vsphere VCD

  Hello

  So I'm new to VCD and try to understand best practices on how to map vcd networks return to networks vsphere.

  I'll start with the external network.

  In my vsphere network I already have a distributed with several groups of ports of production.  This distributed switch is supported by 2 natachasery starting from each host.  The natachasery connect to the ports of shared resources pswitch that allows traffic on all VLANs.

  To set up my network external vcd.  Should I start with a new Distributed Switch groups port dedicated for the vcd?  If so, I guess I would need to devote natachasery to this new dvs?  I guess this new 'external network' should have no access to my production network?

  So what I think.

  1. new DS with a Teddy connected to my cisco switch.

  2. place a single vlan on that port to pswitch coming out just through my firewall to the internet.

  3. create the Group of ports on this new distributed switch

  3. create my vcd external network to use this port group who has access only to the vlan that comes out to the internet.  No connectivity to my network of vsphere production?

  Again, I am new to vcd so feel free to offer a completely different solution.  I'm tryin to figure out how the vsphere networking should be setup to support these networks of vcd.

  
  Thanks in advance,
  Ian

  Let me start by asking what is the purpose of this cloud.  Is it to run systems for yourself, or others (such as other companies).

  This is a quick setup which I think will be works for many people, or at least as a starting place to get an idea how it goes toghether. I used it as a whole little clouds which was a private cloud, so it has worked well for the needs could help by giving you a start.

  In VCenter

  Unique DVS

  4 cards network uplink on DVS

  dvPortGroup to name VMKernel/VMotion "VMotion" VLAN 11

  dvPortGroup to Managment named 'Management' VLAN 10

  dvPortGroup to Internet only traffice name "InternetDirect" VLAN 12

  dvPortGroup to the name of "VMNetwork" VLAN 13 Normal network traffic

  VLAN 14 also install switch as private use to VCNI traffice between fenced of vApp

  In VCLoud

  2 x network provider in VCD Setup

  'Internet only' - pointed the DVS dvPortGroup named 'InternetDirect '.

  'Normal network' - pointed the dvPortGroup named 'VMNetwork '.

  1 x network pool

  'Standard network Pool' - configured to use VNCI on VLAN 14

  For each org (we had some, but they are all very easy company)

  added 2 networks for each and pointed provider networks

  Unless I forget something that that's all we had to do to have a "normal" and the only network Internet and allow VAPP is fenced and have private network segments. -A bit of VLAN, we used could have been consolidated, but we liked the idea of knowing esxi-esxi traffic has been segmented wit ha vlan other speculation.

• Strange host Networking question

  I have a vmware host in a cluster. The strange thing is that all of a sudden when I go to configuration-> network-> vsphere standard switch, I'm not able to see the VMkernel Port with the IP address assigned to the vmkernel port used to connect to the host to the cluster.

  I have attached two files. screenshot1 comes from other vmware host in the cluster which seems correct that screenshot2 however is the host that is not look right. I can always ping the address which does not appear in the vmkernel port and I can connect to this address using the vsphere client. WTH?

  A help is appreciated.

  Thank you very much

  as you go to the standard switch configuration:

  configuration--> network--> switch vsphere standard

  There you have a tab with distributed switch:

• Very slow access to data on HP MIcroserver Gen8 warehouses. Can not change the system of booking resources with vSphere client.

  I did a clean install of ESXi 6 with HP supplied image (ESXi-6.0.0-2494585-HP-600.9.1.39-Mar2015).
  Access to and from the warehouses of data over network via vSphere Client (6.0.0 - 2502222) is very slow - ~ 10 Mbps (there are several hundred under ESXi 5.5)
  I suspect that ESXi 6 limited CPU resources used by the host to 230 MHz system.
  I can't change the settings 'System Resource Reservation"(unlike ESXi 5.5, where I can change and switch to Simple or advanced mode).

  Hey ArnisR,

  I finally found the problem. In the last 5.5 ESXi and version 6.0, they replaced the driver hpvsa (HP ISO vSphere!). With these drivers, I have known major problems with banks of data and, therefore, the controller B120i (RAID) of the Gen8 MicroServer HP.

  The problem is caused by the last (HP) ISO (from March);

  -Mar2015.iso 5.5.0 - Update2-2403361-HP - 550.9.2.27 VMware ESXi

  -Mar2015.iso 6.0.0 - 2494585-HP - 600.9.1.39 VMware ESXi

  I found out (because I had an older ISO), the ISO VMware ESXi 5.5.0-Update2-2068190-HP-5.77.3-Nov2014.iso works well! With this ISO standard, all performance issues disappeared.

  The difference between the ISO is as follows. The former ISO contains the driver of storage scsi-hpvsa 5.5.0 - 88OEM. ISO (s) of March come with new storage driver scsi-hpvsa 5.5.0 - 92OEM or scsi hpvsa - 5.5.0 - 90. These drivers are the cause of the problems in the controller of B120i!

  Installing ESXi 5.5 or 6 since last ISOs, you must manually install the old driver of storage (SCSI hpvsa - 5.5.0 - 88). I tested with the HPSA file scsi vib - 5.5.0 - 88OEM.550.0.0.1331820.x86_64.vib. Then I adjusted the ISO HP and equipped with the old driver. Now I can install ESXi 5.5 or 6 ISO (custom) of HP, which includes the former driver.

  I hope this helps!

• Nested 5.5 ESXi in Workstation 10 Networking question

  Hi all

  I have an instance of VMware workstation 10 running on an HP z600 with guest OS in RHEL 6u3 where I am trying to accommodate a nested instance of ESXi 5.5 for a lab environment.  I have no problem with the guest OS (Windows or Linux) network using deck vmnic on workstation instance.  I have set the ESXi Server also uses a vmnic bridge.  I can connect to the end ESX Server from any workstation on my network with vSphere, but I can't connect to all nested ESX Server virtual machine hosting.  I tried Linux and Windows virtual machines with the same result.  Virtual machines do not seem to be a problem to get my (interesting) DHCP Server IPv4 configuration.  From the virtual machine, I cannot ping the default router.  Ping indicates the destination is unreachable.  I ping the IP of management on the ESX Server from any workstation on my network, but not VM.  Network mgt ESX and vmnetwork are on the same vmnic.  Very simple configuration.  Any thoughts on where to start?

  All ideas, suggestions would be appreciated.

  Thank you

  Hello

  the query service is the best way. You will need to perform a query to external network.

  If you use the SDK (Java or .NET), it is worth noting that the VLAN Id is not properly deserialized by the SDK and as such is not a property of the type queryresult. After a LOT of violin, I discovered that it is accessible through the Get_anyattr property.

  C# method to extract the VLAN ID of an external network vCloud. There are other properties.

  private string GetVlanForExternalNetwork (string networkname)
  {
  QueryService _qs is _vcx. GetQueryService();
  QueryParams _query = new QueryParams();
  _query. PageSize = 128;
  List _filter = new list();
  _filter. Clear();
  _filter. Add (new filter (new Expression (QueryNetworkField.NAME, networkname, ExpressionType.EQUALS)));
  _query. Filter = new (_filter, FilterType.AND);
  RecordResult _result = _qs. QueryRecords(_query, QueryRecordType.EXTERNALNETWORK);

  It is a wick Gets the VLAN registration...

• Problems with vSphere install

  VM experts! : P

  I am very new to VM and unfortunately am responsible for getting ESX4 vSphere4 running on a slide in our chassis HP C3000. So, I installed vSphere4 and encountered some difficulties. First of all, there are four available within the chassis NIC (2 built-in, 2 via a mezzanine card)

  I have configured the Service Console with an IP address in the subnet that the NETWORK card is attached to (10.100.1.180) and the strange thing is that from the ESX console I ping some IP addresses on the same subnet as 10.100.1.105 we are going to say, but not 10.100.1.50. ICMP is enabled on devices, so it is not a firewall simply disabling echo answers.

  Including a screen capture of the screen of networking within vSphere for reference...

  I think that it probably has to do with the configuration of your circuit.  I use Virtual Connect modules, but if I read right then GbE2c modules are leaving entire switches.  In this case, I'm guessing that you have shared resources on GbE2c ports modules.  If Yes, then you MUST use IP balancing hash.  It is not intuitive, but here the rule of load balancing:

  If the switch can use any port in the trunk to return data to the virtual computer, you MUST set the hash IP load balancer.

  If the switch will not only associate one active port in the trunk with the MAC address of the computer virtual both (based on the configuration of your switch load balancing), then you SHOULD NOT Load Balancing IP hash value.

  So, try setting the hash IP balancing and let me know.
