Create a simple internal network between two or more virtual machines

• Private network between two or more virtual machines?

  I've been running an educational network configuration kind of base on esxi to work to teach their colleagues how running things. To do this I create a separate switch, connect the virtual machines to (only) the switch and run Ethereal on a machine with network in promiscous mode.

  Now, I would do it on my laptop. Can I do this with the merger? Can I network machines without connecting to the host (to ensure that there is no additional noise)? Can I configure a NIC in promiscous mode?

  I think the important part of the question is in regards to the networking VMs as they see, but not the host (btw merger networking of information: http://communities.vmware.com/docs/DOC-2527). Basically, it boils down to the host option only and the answer is no.

  In fact, the answer is yes because after that Virtual Machines are started can be simply down the vmnet1 network card and thus isolate the virtual machines between them.

  In other words on the network of Machines target virtual host-only and then start them up to the point where they receive their IP address DHCP host-only server, then in a Terminal on Mac (/ Applications/Utilities /) use the following command in low only Ethernet adapter of the host host.

  sudo ifconfig vmnet1 down
  

  Now the target of the Virtual Machines will be able to communicate only with each other and not the host.

  Note: You must down only Ethernet adapter of the host host after the virtual machines have acquired their IP addresses, because if you down the adapter before the Virtual Machines will not receive their IP addresses.

  The host only allows virtual machines to see the host, but it really shouldn't be any other "noise". Why do you have to be concerned about this?

  On the question of the noise, I think that VMware Fusion actually uses virtual hubs, no virtual switches (even if by mistake, VMware calls virtual switches), there is a risk of bleeding, and this has been discussed ad nauseam and various forums.

• Build a private network between two physical hosts in ESXi 4.0 for VM guests

  Hi all

  I am a newbie in the use of VMWare ESXi for my company testings and I have a question on networks

  in ESXi. In fact, I always do my tests in my VMware Workstation, and it's pretty easy to build a virtual

  private network between two guests of computer virtual and it needed to do more real testings on ESXi environment.

  But now I have two Dell servers mounted and with two ESXi 4.1 installed on these servers.

  Each server has two network cards connected to the same network switch.

  In this essay, I have to install a RAC Oracle 11 g as guests of virtual computer on two separate server Dell for

  two RAC nodes.

  The installation Guide for the PAP, I need to build a network between two nodes.

  My superficial knowledge network, the private network address is not the same as

  the public network address, in this case, the IP address provided by the network switch is

  10.1.10.X and it should be public network address.

  In this case, how can I do the private network of ESXi settings?

  I do the settings of the network switch? I'm not the guy of networking and really

  want your expertise in this area.

  If you have an idea or experience to share, please kindly help.

  Thank you very much

  Yes, that's correct. It would have made you have a private network layer 3 between the two guests in the 192.168.1.x address range.

  In general, you also want to isolate a layer 2 (ethernet) with the VLANS on the physical switch, but if this is not possible at this time then it could be implemented now and you could later add VLAN in the switch.

  It is also the reason why I think you should create a new portgroup on the same vSwitch as other existing exchanges. If you later configure VLAN to the physical switch, it will be very easy to activate this on the "private" portgroup

• Difference between the hosts and virtual machines

  Happy new year!

  I guess that's a stupid question, but I don't know the answer to it.

  I created pools from VM. Some jobs in the pool are hosts and some virtual machines. What is the difference between the hosts and virtual machines. I thought I could only create virtual machines, but I guess I could create hosts as well. -What happened?

  Thanks for your help.

  where does say desktops are hosts?  A host is usually referring to an ESXi server.  A virtual machine is just the guest OS running on the host computer.  A pool is a group of VMs that can extend over several hosts.

• "Limited connection" when you configure the network between two computers XP.

  Original title: Configuration of the network connection

  Trying to establish a network connection between two home PCs., both running Windows XP Pro. Have been through the network on both PC Setup Wizard but, they still say limited, in fact no connection. I use an Ethernet cable between the two Crusader. If it is true what I'm doing wrong?

  Thanx Terry

  Old but good, networking tips from MVP Malke, MS:

  The best and simplest is to buy a wireless router. This way you get Internet connectivity both machines and the added benefit of security more between you and the Internet. Then you configure your network wireless safely, and then you configure file/printer sharing. Here is information on the implementation of a router and also in networking. It seems long, but don't be intimidated. Setting up a router and the LAN of sharing between two computers takes about 15 minutes.

  The router configuration

  Setting up a router is simple enough. Normally, you run the CD that came with the router and follow the instructions. If you're running Vista, maybe the CD that came with the router does not work; I do not know this. But you can set up the router without the CD. Note that if you have Internet cable for the connection you have just set up the router to DHCP (or there may even be a choice of cable to choose). If you have DSL Internet, you select TRP usually and enter the username and password you selected when you initially set the DSL connection. So:

  1. turn off the power to your cable modem.

  2. attach a cable (usually supplied with the router) course Ethernet cat5e Internet/WAN port of the router to the Ethernet port on the cable modem.

  3. connect the ethernet cable cat5e from the network card in your computer to one of the ports on the router. If you do not have an ethernet cable (because you were using USB), you will need to go to the store and buy a.

  4. turn on the cable modem. After that all the lights are on, turn on the router.

  To configure the router:

   

  Have a computer connected to the router with an ethernet cable. Examples given are for a Linksys router. See the manual of your router or the router mftr's Web site. for the parameters by default if you don't have a Linksys. Open a browser such as Internet Explorer or Firefox and in the address bar type:

  http://192.168.1.1 [Enter] (it is default IP address of the router, which varies from router to router then check your manual)

  This will bring you to the login screen of the router. The default username is blank and the Linksys default password is "admin" without the quotes. Enter this information. You are now in the configuration of the router utility. Your configuration utility may be slightly different from mine.

  Click the Administration link at the top of the page. Enter your new password. MAKE A NOTE SOMEWHERE THAT YOU WILL NOT LOSE. Re-enter the password to confirm it, and then click Save settings at the bottom of the page. The router will reboot and show you the box of connection again. Do not fill in the user name and put it in your new password to enter the configuration utility.

  Now, click on the link wireless at the top of the page. Change the network name (SSID) wireless by default to something, you'll recognize. I suggest that my clients not use their surname as the SSID. For example, you might want to name your network wireless network "CastleAnthrax" or similar.

  Click on save settings and when you get the prompt that your changes were successful, click the wireless security link which is just beside the Basic Wireless Settings link (where you changed your SSID). If you have a newish computer, you will be able to affect security WPA2-Personal Mode. Do this and enter a password. The password is what you enter on all computers that are allowed to connect to the wireless network. MAKE A NOTE SOMEWHERE THAT YOU WILL NOT LOSE.

  At this point, your router is set up and if the computer that you use to configure the router will normally connect wireless, disconnect the Ethernet cable and wireless of the computer should see your new network. Enter the password you created to join the network and start surfing.

  B. file/printer sharing of

  Excellent, comprehensive, but easy to understand article on sharing files/printer under Vista. Contains information about sharing printers and files, and the folders:

  http://TechNet.Microsoft.com/en-us/library/bb727037.aspx

  For XP, start by running the Network Setup Wizard the on all machines (see warning in section A below).

  Problems sharing files between computers on a network are usually caused by 1) a misconfigured firewall or a firewall neglected (including a dynamic firewall in a virtual private network); or (2) inadvertently run two firewalls such as the firewall of Windows and a third-party firewall. and/or (3) do not have accounts to the same users and passwords on all computers in the workgroup. (4) tries to create actions where the operating system does not.

  A. configure the firewall on all machines to allow traffic to local area network (LAN) as being approved. With the Windows Firewall, it means which allows file sharing / print on the Exceptions tab normally run the XP Network Setup Wizard will take care of this for these machines. The only "witch hunt", it will turn on the XPSP2 Windows Firewall. If you are not running a third-party firewall or you have an antivirus with "Internet Worm Protection" (like Norton 2006/07) which acts as a firewall, you're fine.  With a third-party firewall, I usually set up the allocation of LAN with an IP address range. E.g. would be 192.168.1.0 - 192.168.1.254. Obviously you would substitute your correct subnet. Do not run more than one firewall. DON'T STOP FIREWALLS; CONFIGURE THEM CORRECTLY.

  (B) to facilitate the Organization, put all computers in the same workgroup. This is done from the System applet in Control Panel, the computer name tab.

  C. create the counterpart of the user accounts and passwords on all machines. You do not need to be logged into the same account on all machines and assigned to each user account passwords can be different; accounts/passwords just need to exist and to match on all machines. DO NOT NEGLECT TO CREATE PASSWORDS, EVEN IF ONLY OF SIMPLE. If you want a machine to boot directly to the desktop (a particular user account) for convenience, you can do this. The instructions on this link work for XP and Vista:

  Set up Windows to automatically connect (MVP Ramesh) - http://windowsxp.mvps.org/Autologon.htm

  D. Si one or more of the computers is XP Pro or Media Center, turn off Simple file sharing (Folder Options > view tab).

  E. create share as you wish. XP Home does not share the users directory or the Program Files, but you can share folders inside those directories. A better choice is to simply use the Shared Documents folder. See the first link above for more information on Vista sharing.

  F. you have the job of file sharing (and tested by exchanging a file between machines), if you want to share a printer connected locally to one of your computers, share of this machine. Then go to the printer mftr Web site. and download the latest drivers for the correct system. Install them on the target machines. The printer must be collected during the installation procedure. If this isn't the case, install the drivers and then use the Add Printer Wizard. In some cases, printers must be installed as local printers, but it is outside this response.

• Need help to set up a network between two Windows 7 computers

  I have two Windows 7 computers at home: one is a desktop computer that is connected directly to the internet (with a network cable), and the other is a laptop computer that is not directly connected to the internet with a network cable.  We have a configuration of wireless network for your laptop is set up of this network and has internet access.

  What I want to do is set up a network between the two of them, so that the laptop can access the printer that is directly connected to the desktop computer.  I got this configuration when both computers are Windows XP, but since we their past to Windows 7 I can not it works.  I tried to create a home network, I set the printer on sharable and given him a name, but I can't access it on the laptop.

  The printer is actually a photocopier, but it is directly connected to the desktop computer.  In fact, it is connected to the router than the phone company provided.  But we want the laptop to be able to access it and use it.  As I said, we had this configuration when these computers are computers Windows XP, but I tried following the instructions to do this for Windows 7 and I can't make it work.

  Also, I'm not that computer savy, so please if you tell me to run a program it please tell me how to find and launch this program.

  Thanks for any help.

  VMWARE product information:

  Ok. You will need to ensure that the ip addresses you assign to your virtual machines are in the same subnet that the adapter created by the installation of vmware. Once you get the fixed basic network installation, you can treat these virtual machines like any machine in your data center. Forget the vm console and access it exactly as you would for any remote server - putty for the Linux and Windows Remote Desktop to the Windows machine.

  To a prompt on the host computer, post this:

  c:> ipconfig -all
  

  You will get feedback on multiple net cards, of which two are identified as with vmware - vmNet1 and vmNet8. Note the IP addresses of the two. We'll need later.
  You'll also need to know how you have configured the network cards on your virtual machine - NAT, bridged, hostonly?

  Note that these issues are out of scope for this forum. I don't mind helping, but I don't have an installation of vmware for details of the reference.

  Which have really tried to do? ( Data transfer )

  It's pretty vague. Exactly how did you try to "Exchange data"? A SQL using a db_link? import/export? Pigeons?

  Where are you stuck?

  I don't know, how to set up the ip address and the necessary information for the windows database.

  Configuration of an IP address is purely a matter of admin OS and out of range for this database forum.

  I tried a lot of things, but now I have no idea what to do or what to try next. It is true that I have no deep understanding of Cisco etherchannels yet, so I guess that my mistake is somewhere in the IOS configuration.

  Thanks a lot for your support and welcome to Germany

  Stephan

  Hello Stephan,

  With EtherChannels, a single flow (the flow of images/packages with the same source and destination) is always carried by a single link only. Implementation of Cisco implements not balancing on connections in an EtherChannel load by package, and it avoids a reason: executives could get reorganized, something this plain Ethernet never should do. This means that you will not see an improvement in bandwidth on the speed of a single link to your EtherChannel for a single stream. It is only the overall bandwidth for several stream which increases. The advantage of EtherChannel becomes therefore obvious that if your server starts many conversations and several stream handling.

• The DDE network between two PCs running windows server 2003

  We seek to transfer data between two excellent sheets (Office 2003). Two excellent books are on different PCs running windows server 2003 and office 2003. The two PC's belonging to the same workgroup. One of them being run by Siemens PCs 7 process control system. I have ensurred running on both PC Netdde.exe. When excellent both books are on the same server they connect perfectly. When I run the client excel book on the other Pc (without changing something in the formulas of cells) the connection is lost. The DDE connection is approved on the PC server and this connection permission is full control for everyone. What is perhaps the reason for this problem? I think I missed a point. Can I get help for this. Thanks in advance for you.

• Why is no longer a faster network between two different hosts?

  Hello community!

  I need help in this mystery.

  I have three computers different virtual, all of them with e1000 (also I tried all VMs with vmxnet3) and the latest vmware tools.

  Two of this mV, are in the same physical host (ESXi 5.5.0 2068190). Call for example: VM - 1A & VM - 2A

  Another virtual machine, is in another physical host (ESXi 5.5.0 2068190). Call VM-1 b

  Both ESXi hosts are connected with two cards 10 Gbit network with load Balancing: "From hash IP route" and detection: "link status only.

  Traffic Shaping is disabled in all Ports.

  The environment is very clean, and we have more VMs that can disrupt the test (or inappreciable).

  VM - 1a: 10.12.50.201 - physical host ESX - A

  VM - 2A: 10.12.50.202 - physical host ESX - A

  VM-1 b: 10.12.50.200 - physical host ESX - B

  Why I don't see better network speed reference, when two virtual machines send something two physical host is different than when the two virtual machines are in the same physical host?

  It is not a question of "iperf", I used the other test with CPS and I had the same speed.

  Thank you very much!!!

  PS: The physical host computers are: Dell PowerEdge r.620 - 16-core Xeon - 384GB RAM

  

  Have you tried to move your VM on different hosts to the same host?

  Your names of:

  VM - 1 a host has

  -VM-1 b on Hots B

  ToDo

  Now move VM-1B for A Host and repeat the test (two virtual machines on the same host). What happens now to the speed?

  Check

  -How is the CPU usage during the test we Host-A, if you have 2 virtual machines on this host?

  -What is your ratio of P2V CPU? (overprovisioning?)

  What it could be

  -Host doesn't have enough CPU power to serve the two virtual machines (or over-provision P2V related problem). But for me no sense if I see your config server with 16cores.

  -It is not a host but a related problem of VM (perhaps it depends on the VM - A2). Makes the most sense for me (your test is to check)

  Please share the results

• Connectivity between two nodes of Virtual Box

  For a few days, I try to establish the network connectivity between two nodes OEL (Oracle Enterprise Linux) in Oracle Virtualbox. I tried everything I have found Google, but still nothing works, everytime I try to ping from one node to another node Hostname/IP is showing unknown host. All the advice everyone here will be great for me.
  
  Published by: 918868 on October 30, 2012 02:30

  When you create a virtual machine, by default VirtualBox allows virtual network card and selects the "Network Address Translation" (NAT) mode for it. In this way the guest can connect to the outside world using the networking of the host and the outside world can connect to services on the feedback that you choose to make visible outside of the virtual machine.

  This default configuration is good probably 95% of users of VirtualBox. VirtualBox is, however, extremely flexible in how it can virtualize networks. It supports multiple virtual NICs per virtual machine, the first four that can be configured in detail in the Manager window. Additional network cards can be configured on the command-line with VBoxManage.

  Welcome to the community-Yes, you need to create a vswitch on host 2 has a virtual machine port group with the same name on host 1 connection on the same subnet as connected to the host - 1

• Two guests of virtual machine running in Bridge Mode connection question

  Hello

  I seem to be a little lost with a problem.  What I've read, VMWare Server is free (I plan to use it in a test environment, which is low-budget).  I installed on a server and got two VMGuests of installation at the moment.  The question I have is that I don't see the first guest that I boot on the network at any time? Anyone who encountered this?  that is, if I start the server A and Server B then, Server A is located on the network without problem but can't change anything to or from Server B.  If I stopped server server B still does not work.  If I stop the server B and then start up with the server still does not, it will work on the network.

  At first, I thought that because it's free it will allow only one server at once, but I don't think it's true.  The only other thing I can possibly think, is that I just copied a basic virtual machine Image I created so that both servers are at the same image.  When asked if I had copied from moved it I chose move, this might be the reason, and I need to select copied?

  Anyone got any ideas please?

  Kind regards

  Looking for a line like the following, with a text editor in the file .vmx for each of your virtual machines:

  ethernet0.generatedAddress = "00: 0C: 29:b2:04:03.

  There may be several entries being Ethernet if you have multiple network cards. That's how the MAC address is set and must match what ' ipconfig/all' or 'ifconfig - a' shows you in this prompt.

  MAC addresses are not totally free but you can manually change the lowest few bytes (for example the 03 to 05 in the example above) or a more correct way is to add another NETWORK card and then delete the original, a copy.

  When you reach the point of having the 'model' virtual machines - where you copy the files manually to a new location to create a new virtual machine - and then add the following line to the .vmx to avoid this problem doesn't happen:

  UUID.action = "crΘer".
