• Distributed Virtual Switch and Service Console

  I have multiple ESX hosts and want to create a vDS for all traffic to the virtual machine. What is recommended for each guest, ESX service console, if these remain on the vSS service or be moved to the vDS? Is it a risk seen your service console on the WIS as losing this switch would then probably keep access you the ESXhosts?

  Also, can someone explain the benefits of using smoothing on the usual IP/MAC hash options of two-way traffic?

  Thank you

• How to change the security policy of a group of distributed in a distributed virtual switch ports?

  Hello

  I am trying to write a Perl script that can modify the security policy of a group of distributed in a distributed virtual switch ports. I can access the values of security policy by using the following:

  
  

  $port_group_view-> config - > defaultPortConfig-> securityPolicy - > allowPromiscuous-> value

  $port_group_view-> config - > defaultPortConfig-> securityPolicy - > forgedTransmits-> value

  $port_group_view-> config - > defaultPortConfig-> securityPolicy - > macChanges-> value

  I try to use the method ReconfigureDVPortgroup_Task() of the managed object DistributedVirtualPortGroup. While creating a new instance of DVPortgroupConfigSpec, within the data spec config defaultPortConfig property object there is property of security policy and I couldn't find any other property pointing me to that I can update the security policy. I discovered that it is accessible via defaultPortConfig, stretching from VMwareDVSPortSetting where securityPolicy is a property of VMwareDVSPortSetting.

  What is the way to update? I am bit confused about terminology Extends and extended by and how it relates to the other.

  Concerning

  Akmal

  It is in DVPortgroupConfigSpec, but you will need to use the extended VMwareDVSPortSetting object.

  My $dvpg_spec = new DVPortgroupConfigSpec();

  $dvpg_spec-> {defaultPortConfig} = new VMwareDVSPortSetting();

  $dvpg_spec-> {defaultPortConfig} {securityPolicy} = new DVSSecurityPolicy();

  $dvpg_spec-> {defaultPortConfig} {securityPolicy} {allowPromiscuous} = new BoolPolicy (value-online 1, inherited-0 online);

  $dvpg_spec-> {defaultPortConfig} {securityPolicy} {forgedTransmits} = new BoolPolicy (value-online 1, inherited-0 online);

  $dvpg_spec-> {defaultPortConfig} {securityPolicy} {macChanges} = new BoolPolicy (value-online 1, inherited-0 online);

  You could probably simplify this by getting the config spec VGA and change it before using it in the ReconfigureDVPorgroup_Task() method.

• Migrating from a distributed virtual switch pass

  I have a cluster that is approved for business-more.  I would like the host to a distributed switch.  The configuration of the virtual switch is as follows:

  4 NICs connected to a host, the NIC are part of an EtherChannel.  The network adapters are teamed up with ip route based on the hash of the IP.  All network adapters are connected to the same vSwitch with port groups created for access to the different VLANS

  I did the following to try to migrate to the new distributed switch: I broke the EtherChannel and removed three network adapters on the virtual switch and assigns them to the distributed switch.  At the same time grouping NETWORK adapters on the virtual channel switch based on the originating virtual, we changed the port ID.  I then migrated the service console more for the new switch successfully distributed.  I have created groups of ports on the virtual switch.

  The question is when I re - create the EtherChannel falls hosts on the network.  I have noted the following: "see attachment".

  Anyone using EtherChannel with distributed switches?

  Any help would be appreciated...

• Distributed Virtual Switch 5.1 update

  Hi all

  We have a vmware vsphere Cluster with 7 v 5.1 ESXi hosts 838463

  We have the form of upgrade version 5.0 to 5.1 ESXi ESXi and vCenter Server since version 5.0 to 5.1 September 2012.

  Now, I noticed that (just a little late...  ;-)) all the distributed virtual switches (we have 2 DVS) need to upgrade.  Version of DVS resulted, in fact, to be 5.0.

  (I saw in vSphere client connected to the server vCenter Server - networking).

  I wasn't expecting this behavior, DVS independent upgrade of host or vcenter server upgrade?

  It is possible DVS upgrade during the normal activity of the infrastructure?

  Thanks in advance

  Anna

  Think about the situation,

  don't forget that a dVS is a virtual switch split on all hosts, if the dVS has been automatically upgraded to the new version and there were incompatibilities or new features that were not available in the switch downstream you might run the risk of a network outage.

  in my opinion rightly done VMware cela a phyiscal post upgrade task,

• How to restore a distributed virtual switch.

  Hello

  I have a question where one of my esx host 4 i crashed and then we rebuild the host vmware and I have the backup of the file esx.conf with me since the day before. I had a virtual switch distributed in the vmware environment, and since I rebooted the backup config that my vcenter does not add the host esx to the distributed virtual switch.

  -How to restore the vswitch distributed on the esxi host settings.

  -When I look on the esxi configuration host configuration file indicates that DVS information are uploaded but vcenter does not overwrite the new settings.

  troubleshooting performed up to now

  I restarted the vcenter and all services and same problem.

  forced file configuration several times and same question

  has taken the esx host that out of the inventory and the same issue.

  any other suggestions.

  The answer to this has been found in Vcenter 5.1 where there is an option to save the DV switch. I connected this bug a few years back with vmware and this problem is fixed in vcenter 5.1.

• Difference between a Standard switch and distributed virtual switches

• Distributed Virtual Switch supporting guests with different numbers of natachasery

  Our environment has had the same ESXi host model for some time. Each has interfaces from 2 to 10 GB for the traffic of the virtual machine. We use a virtual switch distributed with 2 uplinks. Now, we stand at a new environment where there are 2 types of hosts. (1) a small workload ESXi host with interfaces of 2 to 10 GB and (2) a large load of work sESXI host with 4 to 10 GB interfaces. They are seperasted in 2 groups (large and small workload workload).

  I had planned to share a Distributed Switch between the 2 groups, so I could move freely between them according to the needs. The only distinction of level of ESXi host is the power of horse and the I/O bandwidth (storage and networks VM will be used will be the same). It dawned on me that the distributed switch is configured with a particular number of uplinks. I'm trying to picture how this will work in this situation? I thought that I create a vSwitch distributed with 4 uplinks and finish by only using 2 of these uplinks when adding a small amount of work ESXi host to it. This is a valid configuration. Should I disable or do something special with the uplinks unused? I have not met this configuration so I wanted some tips on the correct configuration.

  I have validated this configuration as described previously. A dVS with 4 uplinks can take care of the guests with "up to" 4 interfaces. Hosts with only 2 interfaces will have 2 of the 4 links rising dVS associated with natachasery while the other 2 will remain unused. In my case, I decided to use the uplink 1 and 2. Uplinks 3 and 4 are not used with these hosts.

• iSCSI multipath with Distributed Virtual Switch error

  Ive followed the iSCSI SAN guide and have iSCSI multipathing works well with a regular virtual switch. Ive cancelled all configurations and have begun to see if I can get this working with a dVSwitch.

  Someone at - it ideas?

  I recently worked on a case of iSCSI with VMware support and they mentioned a known issue with iSCSI and dVS, this is also described in the release notes, but may still have a problem. You can contact the technical support for confirmation.

• Full migration to a distributed virtual switch

  Hi all

  When an ESX Server is first installed, it uses a switch vNetwork standard for COS as vswif0.

  When this server is added to the server Vcenter, the Vcenter contacted with ESX vswif0 via the standard switch.

  What is the process to move the vswif0 vDS? Is this possible via CLI?

  A new vswif to create in the vDS with a new uplink, remove the ESX the Vcenter and add it with the new ip vswif and then delete the old vswif of the standard switch.

  Is there a better way to do it?

  Kind regards

  Sharath

  It's better if you could refer to vSS to vDS migration TSB practice.

  In the doc mentioned about 2 x posible to migrate:

  1. the host migrate with some distruption to virtual machines

  2. the host migrate without distruption to virtual machines

  So, I prefer option 1, because you only have a physical nic involved.

  This option includes two steps:

  A. migrating from virtual port (console service etc.) first--so you can always manage ESX

  B. Migrate machine virtual network (Distruption on the network of the virtual computer until step B)

  Host migration with a few disruptions to virtual machines

  The process as outlined in step 3 of the chart includes two substeps:

  A. migration vmnic and virtual ports (VMkernel and Service Consoles) ports can be migrated in one step of

  vCenter Server.

  B. migration of VM networking where virtual machines are migrated from vSS Port port vDS DV groups groups.

  If all vmnic is migrated in step A, then all the virtual machines will lose network connectivity until step b. step B can follow quickly after (that's the step A

  up to the speed of the operator), but active sessions will probably drop. However, VMs may stay lit.

• Network interface 'NIC 1' use the network' Distributed Virtual Switch (uuid :) ', which is not accessible)

  Hi all

  I tried to migrate a virtual machine from one cluster to another cluster that connects to two different dvSwitch, I got an error when I chose to migrate to what host.

  No one knows about it?

  How to solve this problem of deletion of the NETWORK adapter on the virtual machine?

  Thank you

  The two, source host and destination must be connected to the same dvSwitch and the different steps for the migration.

  Even if the port groups have identical names and are in the same VLAN, as long as guests are on different dvSwitches, you can't vMotion VMs.

  So, either temporarily connect a host to the two dvSwitches or design a new dvSwitch to strengthen permanently the other 2, where they actually link the same networks (dvSwitches can cover multiple clusters very well).

  You can also temporarily create 2 standard vSwitches on the source host and destination for migration.
