Prevent communication between virtual machines

• flow of traffic between virtual machines

  If I had 2 machines virtual on the same slide in a M3 of b200 on the same vswitch, is communication on traffic between the 2 vms strictly inside the m3 Server?

  What if I had a virtual machines on a b200m3 and another virtual machine to another b200m3?

  same chassis and the chassis is connected to the FI

  Traffic between virtual machines will stay on the FI or it will mount the switch to basic?

  so, if is blade1 VM1 and VM2 is Blade2 and both on the same vlan
  Traffic will remain within FI or it will go up North to core?

  Both is possible! as I said above: If the entry and exit are on the fabric a RESP. B, it is switched.

  However, it could also be A penetration, exit on B or vice versa and then must go to the North (and get switched L2)

  What if

  Blade1 is VM1 and VM2 is on blade2 but on different VLANS, the traffic will have to hit the correct base gateway?

  Yes!

• VMWare Fusion 6, after upgrade cannot copy and paste between virtual machines, desktop missing files

• 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:

  CLUSTER_01, 01-VM001, 01-VM002, etc...

  CLUSTER_02, 02-VM001, 02-VM002, etc.

  I need to compare the IP address of the virtual machine between these sets so I can see if the configuration of the network of these machines is not changed.

  Please help me get a few lines PowerCli.

  You can try this one?

  $clusters = "cluster-01', ' cluster-02'.

  $vmTab = @ {}

• 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.

• Communication between virtual and real session

  A virtual session may communicate information to the real machine? In other words, if a virtual session running can I send a message or a text to be saved on the actual computer?

  I'm under v VMWare Workstation 7.1.1 on a PC running Windows XP Pro.

  Sure! I'm not sure what exactly mean you by 'send a message or text' but you have several options:

  By default (depending on how your virtual computer was created) under the virtual machine settings > Options > Guest insulation, Drag and Drop and copy and paste are enabled. This allows you to freely drag and drop and copy and paste between guest and host operating systems. If these are not enabled, you can activate them. It's one of the ways safer and easier to share data.

  You can also create, under the ' Virtual Machine Settings > Options > folders ', a file shared between the two. Although some do not recommend this for reasons of performance and security.

  You can share files over the network by using shared folders, just like any physical PC 2 would be to share files. If you don't know how to do this, there are a lot of tutorials on the web.

  It is a bit more advanced, but you can also share a real physical drive (see the user manual). It is the least secure method, but offers the best performance if you regularly share huge amounts of data (several tens or hundreds of gigabytes).

• 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

  | ==============================================================
  | * 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

  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

• 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.

• How can I prevent Windows 7 virtual machines to go to "sleep"?

  I am new to VMWare all this so please forgive my ignorance. Deploying a number of virtual desktops using VMWare View via Dell FX - 100 Zero Clients.  After a few calls for VMWare support all get up and running, most of the time I am extremely satisfied.  However, after 10 minutes of inactivity, the VMs go to "sleep", I have configured Windows mode 'High Performance' and 'Never' all set, I changed the OSD on the FX100 "0 (off), nothing seems to work.  It of something I'll just have to deal with, or is there something that I am missing.  This is important because once we go to full production, these machines will be used in a call 911 public safety Center and must stay up permanently.  Any suggestions would be greatly appreciated.

  I think the script indicates that the machine will go to sleep delete the line. But the damage is done...

  Here is the solution

  Reg ADD "hku\temp\Software\Policies\Microsoft\Windows\Control Panel\Desktop" /v ScreenSaverIsSecure d '0' f - change the value to 0 to prevent the screen lock screen saver

  Also make a check after you run the bat file.

  Hope this will help...

• Unable to ping Virtual Machines within ESXi host (vSphere Home Lab)

  I'm using VMware workstation 9, I have 4 virtual machines created inside the workstation.
  (192.168.1.0 network is defined inside VMware workstation VM network editor)

  Domain controller - 192.168.1.1
  ESX1 - 192.168.1.11 (2 NICs - vmnic0 and vmnic1 connected to n/w)
  Esx2 - 192.168.1.12 (2 NICs - vmnic0 and vmnic1 connected to n/w)
  Management Server - 192.168.1.5

  I have 2 virtual computers created inside the machine Esx1

  machine to SQL - 192.168.1.4
  vcenter1 - 192.168.1.2

  I have 1 computer virtual created inside the Esx2 machine

  vcenter2 - 192.168.1.3

  I can ping all the machines in the administration server - no problem

  Question - I can not ping vcenter1 to sql, cannot ping vcenter1 to vcenter2, cannot ping vcenter2 to sql.
  There is basically no communication between virtual machines with the Esx host and in the whole of the host. Firewalls is disable on all these machines virtual esx internal hosts.

  Any ideas how to solve this problem?

  Make sure that virtual network on ESXi hosts maps are Sunrise promiscous mode networking.
