Sending a network private VLAN virtual

• VMotion: A large private VLAN or several small VLAN for each cluster?

  Our production of VMware ESX 3.5 environment begins to develop very quickly and since we have different subnets 1,000001 million (bad network design), but all our esxHost Service Console is on the same subnet for accessibility, it would make sense to have VMotion all the different of the pole on a large local network separate VIRTUAL private or private VLAN?

  We currently have 3 clusters running in our production environment, with each cluster serving a different subnet for connections to data and mgmt VMs.  These 3 groups all are currently 3 separate private LAN of VMotion.

  Over the next month we will add an extra 2 groups serving two different subnets.

  So my question is, how is another to tackle this task?  You create a new VLAN separate private for each cluster (which is what we are doing now)?  Or you have created a large private VLAN for VMotion?  If you have created a large private VLAN, what problems met?  Performance problems?  Networking issues?  Collisions of data?  All esxHost panic?  SMV panic?

  Your comments on your experience would be greatly

  appreciated!

  Hello

  I did have problems with a large network of VMotion. Or with cluster of specific networks of VMotion. Note that with VLAN possible external of attacks using the VLAN is a matter of trust as the VLAN do not guaranttee security.

• Config network and VLAN

  I inherited a network in a colo data center.

  Current network has a Dell 2724 switch in unmanaged mode. Servers using the 192.168.195.0/24 range.

  A new facility will be 3 vSphere, 2 Dell Equalogic PS4000 hosts and 2 Dell 6224 switches for redundancy.

  The 6224 are segmented into VLAN.

  The new configuration was to use the beach of 192.168.196.0/24.

  VLAN 205 receives data from firewall to the camp and our 2724 switch.

  On the 6224 2 port goes to the old switch 2724. He is member of the VLAN 205 and 405 defined on Trunk, AdmitTaggedOnly.

  ports 3-11 are designted for network traffic from virtual machines and are members of the 405 VLAN defined on the access, AdmitUntaggedOnly

  We now want to virtualize the old servers on the new ESX hosts.

  If I put the IP of my VM to 192.168.196.xx, everything is good, I have full network connectivity.

  If I set 192.168.195.xx, I get no connectivity at all.

  I see no connection of IP range in configuring VLAN.

  I need to be able to transport the two beaches of 3-11 ports, because at this point, I can not change the IP addresses of the old servers.

  What Miss me?

  Allow several VLANS on the same ports of physical switch, you must configure these ports as junction ports switch, which allows the two VLANS. 205 and 405. On the ESX host, create two groups of ports on the vSwitch 'Virtual Machines' - one for each VLAN - and define the appropriate VLAN ID. It's called Virtual Switch Tagging (VST).

• Advice on how best to configure the network adapters and virtual switch in ESX host

  I'm new to VMware and am its implementation.  I got my training a few weeks ago, and now I'm configing my hosts.  I have 3 guests, each have 2 network cards.  There is a virtual switch that ESX creates when it is installed (vSwtich0).  The books said that it is advisable to delete the VM network port of virtual machine that is assigned to the value group default virtual switch and put it on another virtual switch so that you keep your management network separated from the network of the vm for performance and security.  If I do this, all my virtual machines will have to go to 1 NIC b/c I only have 2 NICs per host.  I thought that I have just to keep all my groups of ports on the default vSwitch0 and add my second NETWORK adapter so that I can take advantage of the Association of NICs for redundancy and load balancing.  However, I'm not sure on the performance and the security risks.  Do you have any ideas or advice?  I could also create two virtual switches and put my virtual machines on one which would have a NETWORK card dedicated and put my service and Kernal VM console on another virtual switch with a dedicated network card.  However, in this scenario, I have no fault tolerance or load balancing.  We are a small shop and we have about 10-15 VMs on each host.  I don't have access to b/c distributed switching we paid only for the company (not more).  Thank you.

  Hi and welcome to the forums,

  With 10-15 VMs per box and I guess that I would seriously consider adding two extra cards for each host in the production machines. You could then do something like:

  vSwitch0 - vmnic0, vmnic2, vmnic3 - Console of Service, VM LAN network

  vSwitch1 - vmnic1 - VMkernel

  That would give you redundancy and performance to access your hosts (SC) and also for all your virtual machines. The VMkernel would get a NETWORK card dedicated for vMotion and could be on a separate network. He didn't need redundancy really as if the NIC sank the only issue is that you cannot vmotion virtual machines. In this case you would just move one of the NIC workgroup through to those switches manually.

  If you only have 2 network cards, then I would say having a vSwitch with two attached network adapters and VLAN the VMkernel may be off. I want absolutely to the redundancy of having two cards together.

  Hope this helps,

  Host-Only is VMnet1, you used only NAT. static use of intellectual property and switch to DHCP for now. Make sure that the VMWare DHCP Server service is running. Put network cards in comments to "host-only '.

  Post your host ' ipconfig/all'.

  XP home sp3 can use printer/sp2 vista home premium & files on a network private wireless, but not vice versa. Vista can see xp connected on the entire map, but can not do anything with the icon (it shows the IP etc. When hovered over with the mouse). tried fix & checked all the rest including the settings found on the masses of internet sites. don't think that this problem is so widespread and not final fix?. someone must know the answer. both computers have norton 360 v6. !. two computers use internet very well through the same network switch. two computers worked flawlessly again, no repairs, no reinstall, not zero other problems ever (always ran 360 and first market backup battery).

• Switches 2950 with private - vlan

  Hello experts!

  Do you know if switches 2950 private vlan suport? I have updated to IOS and try to configure PVLAN, but this model of switch is not the interface mode command "switchport private - vlan".

  Best regards

  Rodrigo has.

  2950 supports onboard PVLAN don't, which differs from the private VLAN.

  The following link has the support matrix for pvlan on all Cisco switches.

• How to change the network when the virtual machine is connected, in Vmware ESXi with Perl in Linux?

  Hello

  If someone can answer that the way to change the network of a VM with Perl? I would periodically change the network where the virtual machine network adapter is connected.

  Thank you

  Take a look at the vGhetto repository of scripts, where you can find a lot of useful scripts, including updateVMPortgroup.pl , which may contain what you are looking for.

• Network on the virtual computer is not updated after changing the image or

  Hi all

  I encountered a weird problem with one of the pictures gold.

  What I did:

  1 remove Image network adapter gold

  2. addition of new network card and the new network in the annex

  3. power on the Image or

  have 4 you communicated an ipconfig/renew

  5. check that it is in fact now pulling an IP from the new network

  6. picture power off gold

  7 snapshot

  Now after you apply the new snapshot with the new network adapter to the pool and do a recomposition, still have all VM the old network attached to it.

  What Miss me?

  Thank you

  I think that what is expected - after you create a linked clone, its network settings are retained through operations of discount/redial. To view documents:

  "In the View Composer recomposing and rebalance operations, a best effort is made to ensure that the label of each card network NETWORK attached to each workstation linked clone is kept when a clone related new NICs inherits a new base image. View retains the label of network with a NETWORK card that was in place before the operation to reconstruct or rebalancing as the new base image has an available NIC configured with the same type of network switch. (A NETWORK adapter can be configured with a standard network or distributed virtual network switch switch.) »

• Access to the network in all virtual machines lost after that put 8.1 to level.

  Today, I upgraded my host computer to Windows 64-bit Pro 8.1. I did the upgrade through the Windows store. There are no errors or problems during the upgrade.

  However: The host machine equipped with a Qualcomm E2200 network adapter, and it runs the 'Killer' Network Manager software called at startup. After the 8.1 update, when the machine did its last restart, Qualcomm Network Manager opened with a message that the LSP has not mapped correctly. I clicked 'YES' to remap it. Probably a stupid move on my part.

  Thereafter, I lost all network connectivity in all my virtual machines. I have virtual machines for Windows 8, Windows 8.1 RTM (not the preview) and Ubuntu 12.04 LTS. ALL of them have lost the network.

  The host computer has no network problem and works well after the upgrade.

  Any ideas or suggestions to reset network connections in virtual machines?

  All virtual machines are set to use NAT.

  Oh I have to say also that the host computer is running VMware Workstation 10 and everything was fine and dandy, has never had problems at all until this upgrade/LSP remap thing. I have install VMware Tools in the VM of Windows 8.1, with no effect at all.

  Thank you.

  Two things, I'll try:

  1. go in the virtual network editor and restore settings. The culprit is probably the VMNet to NAT configuration.

  2. If this does not work, it seems that the virtual card for NAT does not somehow. The simplest workaround is to uninstall and reinstall the workstation.

• Mapping of several physical network adapters to virtual network adapters

  Hi all

  I am wanting to know how to combine physical network adapters to virtual nics in Vsphere 4.1. I have a gateway virtualized device that supports multiple WAN connections and balancing on these connections. The bridge is all authentication PPPoE/A, so I need to have separate cards for each PPP connection. So, how can I connect a physical NETWORK adapter to a virtual NETWORK adapter and have all access the same VM virtual NIC?

  Hope that makes sense!

  James

  Right-click on the virtual machine, and then select change settings. On the Hardware tab, click Add, and then add the virtual NICs that you will need.  On the network connection screen, you will be able to select a network label which corresponds to VM port groups you created.

• Add Virtual Machine Port Group vSwitch (network and Vlan ID tag) by Script

  Hello

  I want to add a port group of VM for about 200 guests vSwitch. This can be done manually, but if anyone can help me to do it with the help of Powercli. We have guests organized on the basis of clusters.

  Virtual machine port group.

  Tag network:-XYZ

  VLAN ID: XYZ

  Thank you

  Pranab

  You could do something like that

  $clusterName = "cluster"
  $pgName = "test2"
  $vlanId = "1111"
  $vSwName = "vSwitch1"
  
  Get-Cluster -Name $clusterName | Get-VMHost | Get-VirtualSwitch -Name $vSwName | New-VirtualPortGroup -Name $pgName -VLanId $vlanId
  

  It will add the portgroup to the vSwitch on all hosts in the cluster

• Private VLAN on ESXi 5.1

  We had ESXi for over a year; standard networking is very well.

  But for testing small virtual machines, I wish I could assign IPs private at will (192.168.x.x) and to communicate beyond the host.

  I created a VLAN with an ID on a standard switch but how do their itinerary outwardly by a IP address?

  It's the virtual routers with DHCP built-in VMware, and if not, what people use?

  I used m0n0wall previously - enough lite and OK for Setup - http://m0n0.ch/wall/downloads.php.  You can import the image of VMware with VMware Converter and this is an installation guide - http://aldosoft.com/docs/m0n0wall-getting-started.html.

  For the virtual machine itself you will need to configure 3 virtual network cards.  When you start m0n0wall I'm sure vmnic0 would be the LAN / WAN interface vmnic1.

• Setting up a local network private through the device that extracts public wifi internet

  I travel a lot in a RV I don't have a continuous Internet connection wherever I go, usually a public wifi some Camping I am for. I have several devices that I use, but I don't want that they are open to the public wifi network. I've had people send photos from their phone to my Xbox so that I use and I want to be more secure and control my devices.

  I have a knowledge of basic networking. I was able to use my laptop to connect to a public wifi and then share the connection through Windows on the LAN ethernet port. I then connect that to my old Netgear DGND3700v2 DSL model with its DHCP function disabled. It worked for several months now, and I am able to connect to the ports of my router modem and lan with my devices. But some games on the xbox does not work because I can't redirect ports or control static and other IP addresses. I think that there should be a much easier way to do it.

  I looked in my router Repeater functions, but I don't think that's the way I need to go. I have no access to the routers of the campsites configure them as bases. I need something that will pull simply bind an existing wifi and then deliver this private to my LAN connection.

  Thanks in advance for any advice.

  It worked perfectly. I bought a Netgear AC1200 and easily plugged into the local public wifi. I then wired to the LAN cable/Fiber gray on the Netgear router port and then reset the router ran smart installation thereon and he set up hands down with a new local network on a separate ip address range. Now all my devices independently connect to my router via wifi or LAN and use internet through the Extender without that person outside to get in and I don't have my laptop of aging on all the time to do so.
