• Networking between virtual machines on different hosts

  Hello

  I need some advice on the basic approach to networking between virtual machines, each running on a different host machine.

  Consider the following configuration:

  I have a few processes that are running in a Machine virtual Ubuntu. Call this guest1.  I guest1 race inside a real computer running Windows XP SP3 and VMware Workstation 7.x; Call this host 1.

  I have a copy of this virtual machine that I put on another machine.  Call this Guest2.  I have Guest2 running on a separate physical computer, also runs Windows XP SP3 and VMware Workstation 7.x; Call this host 2.

  Now, I would like to guest1 and 2 comments to make networking with eachother.  I wish they were able to ping, SSH, etc., among others.

  This is where I am stuck. I tried setting the virtual machines to use the bridged network mode.  I tried to connect my router on each computer and manually assigning IP addresses to each host and each virtual computer.  When I do this, guest1 can Host1 and Host2 ping, but cannot ping Guest2 and vice versa.

  What is the right way to do this kind of network?  This seems like an obvious application, if you want to perform simulations on multiple virtual machines residing on different computers on the network.

  I apologize if this is the answer elsewhere, I had to dig and was not able to find the solution.

  Thanks in advance!

  Guests must be on the same subnet, like 'real' hardware machines.

  1 when you copied the VM and then started, what did answer you the question of copy/move? (this determines if a new MAC address is applied)

  2 view each guest and ' ipconfig/all' results 'ifconfig - a' by the hosts.

• No ping between virtual machines

  Hello

  I use VMWARE 7 program... I installed two virtual machines (windows server 2008 and windows 7)... I have attached two pic for each other... .my problem is... There is no rattling between these two machines... I disabled the firewall in both entities... How you can help me in this...

  My respects

  Post edited by: a.p. - changed the subject of the "Greetings" to "no ping between virtual machines.

  I do a bit of practice for MCITP study... In windows server 2008, I use Bridge and in the Windows NAT using 07:00

  Well, I guess you should start your trip MCITP become familiar with the IP configuration and routing

  Addresses that you configured do not work that way. Assuming that the physical - bridged - network (if connected) is 192.168.100.x, you may be able to access the Windows Server 2008, but you will never be able to access the virtual from Windows 7 computer with the NAT configuration, because NAT is running on another network (vmnet8 - 192.168.201.x). Depending on the need or not to be able to access the outside world of the virtual machine, you should consider is instituted two virtual machines with an IP address in the range of vmnet1 (Host-Only - 192.168.80.x) or vmnet8 (NAT - 192.168.201.x). In the case of NAT, configure the virtual machine for DHCP or use IP addresses between x.x.x.3 and x.x.x.127.

• Disable copying files between virtual machines

  When I go to several virtual desktops using VMware View 4, I am able to copy files between virtual machines. Virtual machines are located in various isolated networks. It is a security problem in my organization and how do I disable this feature? I am not able to find any related configuration in sight connection to the server. Thank you!

  I assume you are using RDP as the Protocol currently, correct?

  In this case, you will need to implement some GPO:s in the workstations to avoid copy and paste.

  Look in the 'Extras' folder on the view connection server, there are a number of ADM files that you can implement to restrict all sorts of things.

  Best regards

• Compare the IP numbers between virtual machines

  We host multiple clusters with the same virtual machine test and development. Only the external name is different:

• LUNS shared between virtual machines? How?

  Hello..

  I shared LUN for ESXi host and now I want to have a shared LUN for my VMs too how can I do?

  Logic unit number that I want to do shared is already shared between my esx hos, can now do the same LUNS shared between my VMs? Is this possible?

  Tring to use RDMS, but when I assign shared my LUN shared for ESX host so not able to assign the same to another virtual computer that is located on another host ESX ESX LUN to my VM, its goingfrom

  Any idea?

  Thank you

  Once you have assigned to a virtual machine the RDM will be disppear. However as a virtual mode, there is a hard pointer created in the data store. then go on host2 make sure he has access to the LUN, and then add the pointer hard on the virtual computer via the existing disk option.

• How to configure NTP between Virtual Machines without using Vsphere Client

  I have a group of 8 virtual servers of 5.5 ESXi without an Internet connection. There are virtual machines on each of these 8 virtual servers.

  I did one of these 5.5 virtual ESXi host a NTP server by editing the file /etc/ntp.conf with below configuration and

  started the ntpd daemon. He began to take the time to its local clock, here's the output of ntpq Pei

  IP server 10.108.190.14

  ip address of the client 10.108.190.15

  Server /etc/ntp.conf

  > > driftfile/var/lib/ntp/drift

  > > server 127.127.1.0 maxpoll 4

  > > fondant 127.127.1.0 stratum 10

  | ntpq Pei

  |   refid distance st t when poll reach delay offset jitter

  | ==============================================================
  | * LOCAL (0). LIUX. 10 l 2 64 377 0.000 0.000 0.001

  Then I edited the file /etc/ntp.conf on customers with below configuration but the customer would not synchronize with the server. He

  wouldn t get response from the server. Here is the output of ntpq Pei

  Customer /etc/ntp.conf

  > > driftfile/var/lib/ntp/drift

  | ntpq Pei

  |      refid distance st t when poll reach delay offset jitter

  | ==================================================================
  | 10.108.190.14 INIT. 16 u

  Now, when I configure NPT Client/Server on virtual machines through the Configuration Option under Option Configuration time

  in Vsphere Client everything works fine and the client and the server to synchronize with each other. I checked the file /etc/ntp.conf on both the client

  and the server and it has a couple of restrict 127.0.0.1 and restrict the lines added by default kod nomodify etc.

  So why NPT Server featured when enabled via Vsphere Client works very well, but it does not work when it is configured manually

  in the virtual servers directly.

  I was connected to a vCenter Server Appliance through the VSphere Client and enabled the synchronization of time of the NPT.

  I really need to know how to configure the NTP server without using the Vsphere Client so that I can automate the

  task by writing a python script that would connect to each virtual server and NTP Client/Server configuration.

  Any help in this issue deeply appreciated!

  Thank you!

  You can configure the ntp server without using viclient.

• vCenter storage iSCSI 5.5 and shared between virtual machines

  I have just two 2012 Win computers virtual server in the cluster.  I've prested my iSCSI LUNS and the ESX host can see them and I might add in order to become a data store.

  My VMs Win2012 need to share the storage for a cluster SQL database.  I have never done this and everything I tried at this point has failed.  I tried to create the ROW, but that only worked to connect it to a player on one of the virtual machines.

  I'm sure this is possible, but I'm not even sure where to look.  Is it really that RDM is for or is there another way?  Looks like I have would be sufficient to use the initator iSCSI in Windows to connect to my SAN but that would probably slow.

  Any help would be great!

  Yes it can be done - have you seen http://pubs.vmware.com/vsphere-55/topic/com.vmware.ICbase/PDF/vsphere-esxi-vcenter-server-55-setup-mscs.pdf

• How see Horizon share the GPU between virtual machines?

  Say I have three hosts, and only two have the GPU Nvidia, what happens when I vmotion virtual machine to the host without GPU?  Only VM loses the ability to use the GPU?

  The short answer is Yes (hardware GPU).

  If you have the "3D renderer" option in the game of pool parameters seen on 'Automatic' virtual machine will always be able to power on, but it will use a GPU rendering software (not hardware as your other hosts with an installed GPU).  If the '3D renderer' setting is 'Material' the VM does not power on when you try to run out of the host with no GPU and I think he can not even vmotion over the host with no GPU installed (there should be a check to ensure if the virtual machine is compatible with the host his tent of vmotion for).

  Kind regards

• Prevent communication between virtual machines

  Hi all

  What we have is a VLAN in our network which consists of the entry door and a selection of VM connected to it. What I want to do is to stop the virtual machine to be able to communicate with each other, far from putting each its own dedicated VLAN?

  Anyone else has any better ideas?

  Thank you

  I have.

  You must use standard vSwitch or have you allowed for Distributed Switch? If have a dSwitch you could use the VLAN private and do what you want, i.e. a larger VIRTUAL local network and still does not allow virtual machines to communicate. They would be on a "vlan isolated private" I think.

• Share a drive between Virtual Machines

  Hello

  I'm pretty new to VMware so forgive me if this is a silly question.  I am trying to create a shared drive for 2 different Virtual Machines on the same data store.  Each server has its own C: drive that has their installation in this document, which works fine, but I wish they have an E: drive shared that they can have access.  I tried to add a second virtual hard dirve for each machine and oriented the same file but the frist machine locks the file so that the other lights.

  Is there another way to do this?

  Thank you

  Yes it is not possible in this way. You can use a ROW which could be added as a hard drive in both these virtual machines. For purposes of sharing there are two options i.e.

  Virtual - for this nodes to the same ESX.

  Physics - for this nodes in two different ESX servers.

• I'm not sure how to make it work. 2 guests, 2 virtual machines, trying to keep the traffic on the Server Blade.

  I have two blades on the same chassis running ESXi 4.1, each has an Exchange Server on it. Im trying to keep the traffic between the two Exchange boxes contained between the two. I thought that I could put in the same vSwtich, but looks like I need vDS for this. I don't have this license level.

  Now, I found myself with two separate vSwitches with the same label. network, it shows them on the same vSwitch so they don't transmit traffic. because they are separate switches... my vSphere networking missing a bit... need to study more.

  Since you have virtual machines on different blades that the traffic between the two will have to cross a physical network card.   If you need to segment this traffic, you can configure a VLAN in your network, add a new group of port on each host to ESXi virtual machine and then set up a NIC in the virtual machines to use this group of VIRTUAL LAN port.

  Though the virtual machines on the same host (always) you can configure a single vSwitch.   In this case the traffic between virtual machines would not hit the physical network and you wouldn't need even a physical NETWORK adapter, attached to the vSwitch.

• What is the rate of transmission between the virtual machines connected to the same virtual switch?

  Hi guys,.

  I am trying to determine if the rate of data transmission between virtual machines connected to the same virtual switch is equivocal to 10 GB ethernet or faster.

  Thank you

  If it's the same vSwitch in the same ESX, should be the speed of the bus

• Network sharing between two virtual machines to XP

  Looks like it should be easy, but for some reason I can't make it work.  MacPro with two XP virtual machines running.  I want to share some files between virtual machines.  I tried to put them both in Bridge mode, but I was unable to ping each other.

  Is there anything else I need to do?

  I'm not too familiar with sygate.  As you have discovered, yes Windows Firewall allows for sharing of files across, but it disables ping responses (unless you enable it manually).  If you have Sygate running on one of these virtual machines, I would disable the windows one if you don't have multiple firewalls on the system for you in trouble...

  Open ports 135-139 (TCP and UDP) and also open 445 (TCP and UDP).
