Losing network connectivity in Windows virtual machines

• No network connection between the virtual machines on different hosts ESXi

  I have several 5.0 ESXi hosts in a cluster managed by vCenter Server 5 and I have network problems:

  1. [Host A] running a virtual machine can ping any other computer virtual running on the [host A] great!
  2. A virtual machine running on host [B] can ping any other virtual machine running on [B] home - very well!
  3. [host A] (from the ESXi console) can ping any virtual machine running on [B] home - even better!
  4. [B] home (from the ESXi console) can ping any virtual machine running [host A] - beautiful set!
  5. A virtual machine running [host A] can not ping any virtual computer running on host [B] and vice versa - bad, very bad!

  So basically the problem is that the virtual machines can communicate on hosts. It is a major problem that I need to fix, for obvious reasons.

  Networking on all hosts is configured exactly the same way: a unique and standard vSwitch with a pair of gigabit network cards grouped, vmkernels configured for the vMotion, NFS and network management and a group of ports configured for the VIRTUAL local area network used by the VMs. (vMotion works fine on hosts, storage vMotion works very well too.) All virtual machines are servers Windows (2003 and 2008).

  Reason #3 and #4 above, my assumption is that #5 must be the result of an ESXi/vCenter configuration issue and not a problem with the switches of material upstream. Is this a reasonable assumption?

  Whatever it is, can anyone offer suggestions on how can I fix? It is quite annoying as I'm pretty sure that these hosts are configured in the same manner as those of our production cluster, which does not at all these problems!

  Thanks in advance for any help you guys can provide.

  To be honest, it looks like a problem with your physical network-

  How is the physical network configured - are NIC connects it to the same physical switches? Are the virtual machines on the same subnet? If this is not the case, they are able to ping the gateway sbnet? Can you piing host IP address from the virtual machines?

  I also moved it to a forum more approiate.

• Network connections for the virtual machine

  I have recently (1 year) past my office from a Windows computer to an iMac under 10.5 and VMware Fusion. My virtual machine is a member of our corporate domain.

  I can log on to the domain, and after making only two entries in my hosts, outlook, mapped file banks, etc. excellent work! However, here's my question...

  We use VNC widely remotely manage to help control our machines 100 + on our network. Our network is a network of class 10.25.1.XXX, and yet the VM is given an address 192.XXX.XXX.XXX in NAT mode.

  If I want to leave the running virtual machine and connect from work, I can't do my type in the 192.XXX.XXX.XXX as address/subnet is not in our routing tables.

  I'm not a network administrator, just the humble CEO of my company. Am I missing something?

  Thank you...

  Mr. bubbles

  I can't give advice on how get VNC running through a NAT configuration, but another option would be to give your virtual machine a network connected by a bridge instead of NAT configuration.  Then your VM would have its own IP on your network of 10.25.1.x.

• regarding the connection of the virtual machine to the external network

  Hi all

  I'm new to vmware and I have two virtual machines with windows operating system 7. How to connect to the external network?
  can I assign a NATed IP to them?

  If the need to talk about virtual computer internally, you can add all the VM in the same VSS(vswitch 1) at the same port group Network2 VLAN40. for virtual machines on that VLAN can communicate among themselves without problem and configure all virtual machines with IPs in VLAN40. no need for an another vs.

  For internet access, first check with your network administrator, if the VLAN has a routing or this VLAN has access to the DNS server that provide internet or the proxy server for internet access. He will confirm. or you can also check if this virtual machine are able to ping your DNS server or proxy servers. If its power of ping so it has access to this network. Configure the virtual machines that you configure a physical computer for internet access.

  If the VLAN has access to the internet, even that you configure the physical server with connection DNS and proxy for internet access only the configuraiton even here too in the virtual machine.

• How to connect to a virtual machine remotely.

  How to connect from my PC (windows xp) homepage to my PC(windows xp) desktop with a virtual machine.

  I want to connect to this virtual machine from home. How to do this? What are the steps?

  Thank you.

  Hello

  When you configure the virtual computing, r put his network card to use the host adapter.

  In this way, the virtual machine will get the IP address of the router and will basically act as if the Chickadee is an independent computer in the network.

  As long as the host computer and the virtual computer on and don't go to sleep, you can connect to each on its own through the network.

  or on the Internet.

• Students cannot "connect/disconnect the virtual machine's CD/DVD devices.

  I will start with this context (and apologies for the wall o ' text): I'm a newbie.  I took the course VMware local community college offers [VMware ESXI Server Enterprise (CIS197)], but I've not yet certified. And I don't have a real experience, except what I have taught myself so far.

  I recently accepted a position of learning associated with the College (think: glorified lab tech). I was tasked to work with stuff from VMware in the laboratory (among other things such as Cisco and Juniper equipment). There is no pass-down information like the previous left the position four months ago.

  We have a single host running ESXi 348481 4.1.0. "We have vCenter Server (5.5.0, 1312298), running on Windows Server (2008 R2, Enterprise Edition).  Access host and vCenter through two different IP, addresses using the vSphere client (either 5.5 or 4.1, using a single application - depends to know if I connect to the host or vCenter).

  At that time, the host is using local storage only (we have plans to change this, but it will take time).  The host is not a production on its own server, because it does not have a school systems.  He does, however, run a number of virtual machines in the lab, students use (Linux, Microsoft, Web design, etc.).  So, right now, I can't take it down.

  I was tasked to create a number of virtual machines that students can use to make the basic labs of Microsoft Windows 7.  So far, I have:
  -Created users, one per student, on the host.
  -Creating VMs, deploy one per student, I have a gold model vcenter.
  -Creation of roles to limit the access of students to just their VM attributed, which they access via client vSphere.
  -Created a Windows Server 2008 R2 domain controller that is also a DHCP server.
  -Created a virtual network, which is accessible only by the Windows 7 virtual machines and is not visible outside the vSphere environment (if I said this right - he does not see the Internet or school network).

  So far, it's all good.

  However, I need to be able to allow students the ability to edit the ISO file on which their VM points in order to complete some laboratories. I guess they would use the button "connect/disconnect the virtual machine's CD/DVD devices" on the taskbar (or console window). It does not work.
  I searched a lot and found that others have had the same problem.  However, all of the solutions I've tried so far have failed.  When they click 'Connect to ISO image on the data... store. "they get an error message means nothing to me,"an internal error has occurred in the vSphere Client. Details: Object Reference not set to an instance of an object. Contact VMware support if necessary.
  The role that I use for students has these settings:
  -Data store > Browse the data store
  -Virtual Machine > Configuration > change the settings of the device
  -Virtual Machine > Configuration > settings
  -A bouquet under the virtual machine > Configuration >
  -Configure CD media
  -Console interaction
  -Connection of the device
  -On
  -Power off
  -(and more, which I don't believe are important to the question)
  -State > create the snapshot
  -State > go back to the snapshot

  I tried "Virtual Machine > Configuration > add existing disk", "Virtual Machine > Configuration > add new disk" and "Virtual Machine > Configuration > add or remove an instrument" with no luck.

  Either by the way, the root account can do all these things, but no other account can - not even a game as an administrator account.

  I've seen mention I have apply the role in the data store.  It is perhaps part of the problem. I can't see the data store when I am connected to the host (wellll, I can, if I click on the host name, then on the Summary tab - but roles do not apply at this stage).  I see is 'Inventory' (which has virtual machines and Pools of resources), 'Rôles' and 'log files '.

  I can see the data store when logged in vCenter. Roles of students, however, are defined on the host computer. If I clone the role of users in vCenter and change this role cloned to have "permissions" that those who are on the host computer and then apply it to the data store, it still does not work.

  So, after all this (which I hope I've included all the necessary information), what can I do to allow the students to change ISO to which they are connected?

  Of course, if I left something, or if someone has a question, please ask.  I want to get this resolved as soon as I can.

  It turns out that I finally found the solution to the problem.

  What 'fixed', it is sufficient to vSphere Web Client to vCenter, which then allowed us to use Single Sign-On (SSO).  This, in turn, allowed us to define users and roles in vCenter (rather than having set them up directly on the host computer) which have then been applied to the VMS of students and also to the data store.

  Now, they can (de-) connect their ISOs at will.

  I find it interesting that vSphere Client (application) shows the users (and the things that they have access to), but it won't let you set of users.

• Dedicated network adapter to the virtual machine and the host computer not let can visit his profile

  OK, here's my question, I know how to give themselves a phyiscal nic to a vmware, but I wanted to take it one step further and do not leave the host send or receive data from this network card, only the virtual machine can use this network/NIC...

  Here's my reasoning, I have to network conections, one is for my internal/field network and the second is a direct connection to the internet (Comcast) I don't want to use to separate the machines have for internet connection, I want to be on the same machine phyiscal and have just the vmware machine talking to comcast... is it possible?  I am running VMware workstation 7, last update.

  Thank you

  Cdrshm

  I assume you are using a Windows host?

  If Yes...

  -first set up networking networking with vmnetcfg.exe

  -assign vmnet0 to the network card for the internal network

  -assign vmnet2 to the network card used for direct access to the internet

  -Right-click on the map network-icon in the systray and access the properties of the network adapter for vmnet2

  -Disable all other protocols and the Protocol of vmware_bridge for this network adapter

  result: a virtual machine that uses vmnet2 can directly access the internet and the host has no IP address for this network adapter - and therefore cannot use it.

• whenever I have to connect to the virtual machine asks me to enter login and password I can't save the credentials

  Hi, I used Windows Virtual PC XP mode for awhile and I just do a fresh install, and I'm having a problem that I seem not to be able to solve.

  After you enable the integration features, I got to the Windows Security login screen. I typed in the login and the password, but I accidentally made a mistake and could not connect. I clicked on cancel and was then in the XP login screen, where I entered then the right login and password and it me connected to the virtual machine XP without problem.

  Now, the problem I have is every time I connect to computer virtual it asks me the login and the password on the login screen of XP and I don't have the option to connect using the login Windows Security screen, so it do not give me an option to save my password and login information. So, to make things worse is that moment every time I have to resize the virtual pc it then asks me to log in again.

  Is it possible to return me to the Windows security login screen where can I put my login instead of the XP login screen when it is not an option?

• Powecli set IP for a Windows virtual machine, IP pool

  Hello

  I followed all the steps in this article https://pubs.vmware.com/vsphere-55/index.jsp?topic=%2Fcom.vmware.vsphere.networking.doc%2FGUID-DBF79F52-925A-4D0D-893C-49B911D3AC54.html and I need the following to make it work,

  1. pursuant to article when an IP pool is configured, mapped to a portgroup VM in this network is VAPP options enabled and I put it in the static pool of IP.

  2. so when a virtual machine is on the network adapter in the virtual machine must be assigned an IP address from the IP pool.

  3. but VM NIC adapter gets never assigned with an IP address from the pool and VMware have confirmed this IP pool do not have a capacity to push an IP address to the virtual machine.

  I'm looking for a script that can be kept inside the virtual machine and pull an IP address pool option or VAPP machines IP and assign the adapter NIC VM (Windows). Probably via the VMware tools? Let me know any possibility for that?

  The use of IP pools is like poking yourself in the eye. It feels better when you stop

  If you cannot use DHCP and must use IP pools there are a ton of up front configuration mucking about to make:

  1. Follow the first article you have linked
  2. In the options of vApp for the VM in properties and then create a property for each of the things you want to get the pool of IP (IP, etc.). When to create the entries under type select dynamic property can find the correct entry in the drop-down list then the values come from the IP pool
  3. 
  4. Set up an auto start task (a scheduled task that starts at the start) in your model of virtual machine to run a script that:
     1. Expect that VMware tools start
     2. Run vmtoolsd to get the values of vApp in the VM in XML format
        1. 'C:\Program VMware Tools\vmtoolsd.exe-' cmd 'info-get guestinfo.ovfEnv '.
     3. Parse the XML file to extract the intellectual property, etc..
     4. 
     5. Run the OS commands (netsh, wmic, vbScript (wmi) or Powershell (perhaps native, perhaps wmi according to version)) to take the values from the XML file, and then set the operating system options

  Outside this configuration he plays poorly as the 'network' in the dynamic property is bound to a group of specific ports. If you try to deploy widely, this means a VM model by group of ports (blech!)

  Hope this help to help you started (or persuade you to use DHCP)

• Unable to connect to a virtual machine

  Hey, I am unable to run one of my virtual machines with VMware Player or workstation.

  The error I get is "fatal error VMware Player: (vmx).

  0xc0000006 (disk when paging error) exception occurred.

  A log file is available in "7\vmware.log C:\Users\Peter\Documents\Virtual Machines\True Windows Virtual Machine.

  You can request support.

  To collect the data to be submitted to the technical support of VMware, run 'vm-support.

  We will respond on the basis of your right to support. «and what comes immediately after is "power error: cannot find a valid peers to connect to.»

  If you want to know how it (possibly) happened, I put my Virtual Machine in a suspended state, but he took a while to make my computer shifted so I just shut down my computer and it's been like that since. All other virtual machines that I played.

  This could is related to a corrupted file .vmss in the folder of the virtual machine. The .vmss file stores the information of the previous day and due to the closure may not have been written correctly. Try to remove/rename the file .vmss to see if this allows you to turn on the virtual computer.

  If this does not work, please report (attached) latest vmware.log in your next post the VM.

• Unable to connect to the virtual machine after adding new eSATA drive

  Hello.

  I'm trying to connect my new 2 TB drive in VMWare Workstation. It is connected via eSATA to the host computer, and it works. I added the drive to the desktop as a new "physical disk." But now I can not power the workstation the most.

  (1) when I start the VMWare Workstation it right ask admin (it didn't need before).

  (2) when I turn on the prompt does not charge even the bios. It shows a rear screen with the logo of VMWare for a while and then stop saying: "VMware Workstation cannot connect to the virtual machine. Make sure that you have the rights to run the program and access all directories that it uses and access rights to all directories for temporary files. »

  The host is running Windows 7 x 64. The workstation runs under the standard user account.

  Thank you.

  Hmmm - it's unexpected - works for me here - only difference: I tried with only 1 TB disks.

  You start Workstatiion as an administrator?

• Disable the network interface on a virtual machine

  Hello all-

  Is there a way to disable the network interface on the network adapter in the virtual machine?  We have a group of applications who want to simulate a network in collaboration with MSCS failure - I don't necessarily agree with the fact that this type of test, but try to determine if this is possible from the functional point of view.

  Our ESX host have networks of virtual machine set up off the coast of 4 port nic mezzanine card, and I don't want to touch the VM network vswitch as any part of this test.

  Thanks for any help you can provide-

  Steve

  Is there a way to disable the network interface on the network adapter in the virtual machine?

  Yes, in the virtual machine settings, for each NIC assigned to the virtual machine you will find a checkbox 'connected '. Unchecking it's like pulling the network cable.

• Unable to connect to MKS: virtual machine configuration file does not exist

  Guys,

  Need a little help I'm running the following

  vCenter Server 4.0.0 (build 208111)

  ESX Server 4.0.0 (build 208167)

  I have a computer virtual running WIndows 2000 Advanced and when I try and open the console I get a black screen and the error message following

  "" Unable to connect to MKS: virtual machine configuration file does not exist '. "

  I scoured the data store and all the files of the virtual machine appear to be in place, I thought deletin the virtual machine from the inventory and add the vmdk file, it would be a good idea?

  Thank you.

  Remove and add new inventory won't hurt (you could lose data historial for virtual machine), it probably won't solve the problem.

  I doubt, it is a problem with the .vmx file, but you can try:

  -Remove the VM of the inventory

  -To create the new virtual machine (with the same characteristics as the virtual machine that you removed), name it differently and do not add hard drives that it

  -Change the new VM settings and add the existing VMDK virtual machine that you deleted

  -Power on VM and try

  • You should always have your complete file to the virtual machine original intact, in case you need, you will always have your original vmx file to add it to the inventory.

  By doing these steps you re-create the vmx file.

  f this post was useful/solved your problem, please mark the points of wire and price as seem you. Thank you!
