How to set up the virtual switch vmnet0 so in fact, it behaves like a switch.

Hello

I have a problem:

My configuration is:

host of CentOS 5.3 using vmware server 1.06

3 clients (all centos 5.3 with vmware tools) installed

web01

DB01

backup01

The three guests have public ip and use the bridged (vmnet0) network

The backup01 backups web01 and db01 every night.

My supplier can see that traffic on its poort switch that connects the host to the internet, and he wants to charge me for it.

The three guests (and host) are all on the same subnet. It is the local subnet traffic that does not use a gateway.

It seems the traffic between hosts is diffuse on my physical eth0 on the host. When I have some files between guests, it also appears on the page from my supplier of PCs followed AY. (Just likecommunication between 2 physical host computers are on the local network when you use a hub instead of a switch)

I thought it was probably the only way to vmware would work when using network bridges. Because the host doesn't know anyting on the clients ip numbers.

But when googleling abot this I found several docuemtents (for vmware server 2) telling me that vmnet0 is actually a sort of virtual switch.

If this is true this virtualswitch should know other mac adressess clients (arp who a..) and she must stop the internal traffic to leave the material.

Is not what is happinging. It looks more like a virtualhub instead of virtual switch.

So I was wondering if there are ways to configure the vmnet0 somehow. I was hot, but I can't find anything about it.

I don't want to change the bridged mode or coz internal use of the intellectual property of the plan is to spit the separate web01 and db01 to vmware guests in the furture.

Does anyone have any suggestions?

My idea was to put an additional physical switch between me and my switch to suppliers, but that seems to be a ridiculous solution.

Any help is welcome.

Hans Groot

VMserver don't use virtual switches: it uses virtual hubs. They are mislabeled - probably because "virtual switch" sounds more sexy than "virtual hub".

You can't change their behavior to be more like a switch

  • How to set up the new switch/ports/NIC for MS iSCSI initiator

    Hello

    I'm looking for data on our main server snapshot and then include it with our VM through scripted admsnap commands. I found that the only way to attach/detach when the server is running must be involved in the Microsoft initiator path.

    I am now tripping over the implementation of networks necessary for this virtual machine display the SAN using the initiator.

    Our up to date is:

    vSwitch0 that vmnic0 & 1 (range 192.168.1.x) and is used for LAN traffic for the virtual machine

    vSwitch1 that vmnic3 (192.168.252.x range) and is used for SAN storage processor has

    vSwitch2 that vmnic2 (range 192.168.253.x) and is used for SAN B storage processor

    http://i44.Tinypic.com/20pezr4.gif [line] 

    Our ESX box can connect to the LUNS on the area of SAN ok but I just can't get the same ping VM after the addition of two new network cards and to configure them with the correct IP address, which I suppose is because the 192.168.252.x and 192.168.253.x ranges are not present on the virtual machine and there is this problem I would appreciate some advice on SAN storage processors. How you allow the virtual machine is to use vSwitch0 & 1

    Thank you.

    I'm guessing that you have added two new adapters with the label 'VM Network' network to this virtual machine?  I'm also guessing that vSwitch0 has no access or routing to the storage network.  If so, you will need to do is change the vSwitch1 and vSwitch2 to add a new type of virtual machine connection.  Click on the 'Properties' link beside vSwitch1/vSwitch2 and in the tab "Ports" click on the button 'Add '.  Choose 'Virtual Machine' in the type of connection, it give a descriptive label and click Finish. Then return to the virtual machine (change settings) and change the network connections in your virtual machine to point to the new label, that you just created.  Finally, configure or verify) addressing IP in Windows and try the Ping again.

    Good luck!

  • How to leave the virtual switch as a physical switch law in esxi 5?

    Hello.

    I have Esxi5 installed on a server with 3 physical network card (they are supported and found in Esxi) on that Esxi I installed a virtual-SIN (NexentaStor) machine. The first network adapter is connected to the router, the second network adapter is connected to a PC. DHCP is enabled on the router. Normally on a real switch all connected pc should automatically get an IP address from the server (router), or must be able to communicate when they have a fixed IP address. This does not work on the virtual switch. One of my virtual pc Gets an IP address in a range of false, and I can't connect a real PC at this switch

    2 questions:

    1. Should what settings I use in esxi5 to get virtual pc the good IP address?
    2. Is it possible to connect a real pc directly to the second NIC in my esxi server and use the virtual switch as a true switch? In this way, I can use the Gigabit Nic for a fast and direct connection to the virtual NAS and can connect to the internet via the switch?

  • How can I move the Virtual Mode of Windows XP hard drive to another drive

    How can I move the Virtual Mode of Windows XP hard drive to another drive?

    TIA

    Hi Benyl,

    The vhd in programfiles basis cannot be moved or renamed, if done, xp mode stops at the start.

    To move the files under c, first to boot xp, instead of save mode the machine virtual., turn it off. (settings to prompt the user for action narrow close). Close the machine virtual., and then choose stop. This will remove the vsv file. Do not delete the .vsv file because it contains data if you have not registered in the virtual machine.

    Now, move it "C:\Users\CHRIS.domainname\AppData\Local\Microsoft\Windows virtual PC\Virtual Machines\Windows XP Mode.vhd" to a desired location.

    Parameters of xp mode open, go to the hard drive 1 setting and reposition the hard drive to the new location of the vhd. You should now be able to start the virtual machine.

  • How to set up the password disk HARD on Equimum L40-141?

    Hello

    Can someone tell me how to set up the hard drive on my laptop password above please?

    Thank you
    Jane

    Hello

    Have you checked the settings in the BIOS?
    My BIOS contains an option for the HARD drive password parameter.

    But just a question; Why do you want to set the HARD drive password?
    Is this really necessary?

    You need to know if the HARD drive has been fixed, and that something will go wrong, I mean that if you would forget the HARD drive password, the HARD drive would be locked and is no longer usable.
    So be careful with this password if you want to know my opinion; Don t pay.
