Virtual Machine network problem

• Unable to add the virtual machine network services

  Hello:

  I already read that warning Virtual PC 2007 is not compatible with win 7-64.
  However, I read that it is "unofficially" possible launch.
  OK, I installed it and it worked except networking.
  Basically, I need to install the Virtual Machine Network Services.
  I right click on my network card-> properties-> install-> services-> virtual machine network services (VPC2007 folder: where I can see VMNetSrv.inf)
  Then says Windows: it is impossible to add the requested feature. The specified service has been marked for deletion.

  The problem is that I get this error even on WinXP SP3, so I think that there is something else wrong.

  And of course, Virtual PC 2007 available networks are only: no connection, Local, NAT.  (Missing my physical adapter)

  Thank you!!!

• More than a Virtual Machine on vSwitch\Virtual Machine Network will be NOTconnect

  I have a problem when I start more than one guest on a single vSwitch will connect to the network.

  I have a DELL of 710 with 4 network cards installed.  2 of them are assigned to network management.

  I created a vSwitch1 using 2 other network adapters and that assigned to the virtual machine network.

  I then can't get one of the Virtual Machines to connect to the network.

  Then, I created vSwitch2\Virtual Machine Network2 and use 1 NETWORK for each virtual network card and can then get 2 connected Virtual Machines.

  Any help would be appreciated

  Thank you

  Sounds like your network switches is configured to only allow one MAC address per physical port.

• Change the amount of vCPU in vCD deletes the virtual machine network connection in vCenter

  
  It is a problem of crazy that we discovered, and I wanted to know if anyone had seen him.

  First of all, we miss the following software versions:

  vCD: 5.1.1.867405

  vCenter: 5.0.0 Build 913577

  ESXi: 5.0.0 build 1024429

  If you go to vCloud Director and change the material properties of an existing virtual machine (Powered off) any change in the amount of vCPU (to something new), inside of vCenter status of the network will change to the port group Standard (inactive) none.

  
  Even if, before making the change, the virtual machine is connected to a distributed port group, and works well.

  We now display an SR to VMware, but sometimes it is worth running this by the community to see if other people have already seen or indeed want to test on their deployment.

  
  Thanks in advance

  We have solved the problem now.

  The reason why that we faced this problem is because we used the wrong order in the API.

  You must ensure that you use the undeploy command when you work with the vCD API otherwise you end up with a disconnected network card.

• Virtual machine network adapter is not visible

  Hello

  I complaint customer that they are not able to get the connectivity, then I checked in troubleshooting vm and not founded then is no network adapter in this machine special vm,

  Please suggest what will be the root for this cause.

  Hello

  I believe that VM used to have a network card installed once?

  You can think of your VMS from hardening. By default, each user who has remote access to the VM can eject the NETWORK card using the windows function to eject removable devices. It's what could have happened to your customer.

  To avoid this problem, you can add several custom in the vmx file settings. To avoid removing the devices that it would be

  isolation.device.connectable.disable = "true"
  isolation.device.edit.disable = "true"
  

  for example. But there's more.

  Please see the guide to hardening vSphere 5.0: http://communities.vmware.com/docs/DOC-19605

  and this tutorial interesting by William on explaining how to strengthen your virtual machines automatically through scripts in vCenter: http://blogs.vmware.com/vsphere/2012/07/automatically-securing-virtual-machines-using-a-vcenter-alarm.html

• Virtualized ESXi5 - network problems with nested VMS

  Happy new year!

  I am facing some issues on my test environment, which is as follows:

  • -my host system is a step of laptop Linux Mint 11 (2.6.38 - 8-generic #42 - Ubuntu SMP)
  • -I'm using VMWare Workstation 8.0.1 build-528992
  • -J' I install bridged networking on a virtual interface (made with brctl) for all virtual machines and the host provides dhcp, dns, tftp, etc... facilities
  • -All virtual machines are on the network briged and all see each other, the host and the internet perfectly well

  Now the part ESXi:

  • -the server ESXi 5 (free basic license) is vitualized with a single vnic and bridged networks (same as all other virtual machines) and as a virtual machine of ESXi 5 (was a nice surprise to see that the 8 WS knows out-of-the-box)
  • -J' I install that some virtual machines nested in this virtual ESXi
  • -the VM ESXi can talk to other systems, that is, the host, the other virtual machines and its own virtual machines

  The problem is that nested virtual computers can talk to each other or the console, but not to the computer host or other virtual machines, except the ESXi itself.

  I have tried the following with no chance:

  • -Add an another vnic to the ESXi and devote a vswitch for virtual machines
  • -use NAT or network invited only for the VM ESXi
  • disable/unload the ESXi firewall

  The only thing that works are a little DHCP, although it seems the acknowledgement never reach nested VMs. However, they still get a correct, but after that IP address are not able to receive any ARP traffic. If you manually add arp entries and can see CIMP inquiry vnet0 (bridge) of VMs nested to other machines as well as the corresponding answers. If ping on the other hand, I see only the applications, which means that the traffic is not sent to the nested virtual machines.

  The vswitch ESXi is configured to accept the promiscuous mode, change MAC address and forged passes.

  Thanks in advance if anyone has an idea

  "Promiscuous" mode is enabled for/dev/vmnet0 on the physical host?  See http://kb.vmware.com/kb/287 for more details.

• Assign a port to a specific virtual machine network and combine ports

  Hello

  I have two questions.  1. is it possible to assign a specific to a single virtual computer network port? and 2. I can aggregate multiple physical port to act as 1 and have a virtual port to VMS?

  I'm new to VMware so please forgive me if this is a fundamental issue.  I tried googleing the issue but did not have much luck.  I have a Dell R710 with 4 physical network ports.  Currently all the virtual machines on the host sharing a port.  I would like to use one of the ports and assign it to a specific virtual machine and only this VM.  One of the virtual machines is my / home server and NFS exports him / home dirs to other systems.  This virtual machine will be cumbersome to use network.  I want to assign its own network for its traffic port does not impede the movement of other virtual machines.

  I would also like to consolidate other ports into a single virtual port.

  If you can tell me a document that explains how to do this, I would be very grateful.

  Thank you

  Welcome to the VMware communities forum.   With the default installation of ESXi, a single virtual switch (vSwitch0) is created using vmnic0.   If you want to add additional NIC ports simply go to Configuration > network and then click the properties link to the vSwitch.  Click network adapters, and then click Add to add another NIC port.   ESXi then balance the network traffic load.

  You could dedicate a NIC port to a virtual machine, but possibility of ESXi to balance the traffic load I would simply add additional NETWORK adapter ports to vSwitch0.  If your network needs simply to include VM and management traffic, then I would have simply put all 4 ports NETWORK card in vSwitch0 and let ESXi manage traffic.  This way, you get as much redundancy.

  If you use network storage for your virtual machines (such as iSCSI) then you can consider segment this traffic.  In this case create you a new vSwitch and that a link to 2 (i.e. 2 NETWORK ports for iSCSI) NETWORK ports and then other 2 NETWORK ports in vSwitch0 for ranks of VM traffic.

• Hardware Virtual Machine update problem

  We have recently updated our vSphere infrastructure.  We have successfully upgraded tools from VMware and the hardware version 7 on all our servers, except one.  The vCenter server is physical, but the SQL Server server hosting the vCenter and databases update manager is a virtual machine.  I was able to update the SQL tools, but when I try to update the material it fails.

  VCenter Shutsdown whenever SQL Server to update the material, it loses the connection to the database, which causes the upgrade of equipment to fail.

  I guess that it is a fairly common problem, but I could not find a solution for this.  Anyone have any ideas?

  Thank you

  Can upgrade you the hardware on a virtual computer if you are connected directly to the ESX host?  (I checked, but he has not seen anywhere)

  Yes, see my previous post.  The virtual machine must be turned off.  Then right click on it and "upgrade virtual hardware"

  If I disable the SQL Server (that hosts the vCenter DB) so I can't connect to vCenter to tell the virtual machine to update its equipment.

  You must stop your vCenter Server Service, and then turn off your VM SQL by connecting directly to the ESX host in which it is registered on.

• A specific virtual machine performance problems

  Hi all

  I was wondering if you could help me to check where is the performance of a particular VM bottle neck. I followed a few PDF guides and guide of yellow brick on esxtop thresholds and nothing seems to be in its place, with the exception of this metric named % LAT_C. What I've read, it's the amount of time it takes to wait because of the affirmation of the central processing unit.

  Attached is a screenshot - the virtual machine is AU_ENG_BUILD - this is our server to build in Australia

  If you have 12 logical processors.  and about 44 vCPUs on this host.  also remember that although VMware now has locking opportunisitc. That is, it will take only 2 logical cores if there is a cross-thread call.  I assume that you are using SQL and Exchange, etc., these are applications that support SMP that will lock multiple logical processors each cycle.

  try to evacuate some of the SMP guest to another host and even on the charge and then rerun ESXtop.

• Slow access to the virtual machine network (Windows 2008 Server 64-bit) Windows 7.

  Hello.

  I have a problem when you access files shared on a Windows 2008 Server 64 bits on a client computer to Windows 7. It takes a long time (up to a few minutes) to for example open a Word file from the network share. It is not always, but quite often.

  This also happens on two different servers client with almost the same equipment. Which is a basic IBM x 3400 with hard drives in RAID. I disabled the feature of unloading TCP/IP on the network inside the VM card.

  Someone has an answer for this? Have I missed something, a configuration perhaps? I'm totally lost here...

  Kind regards

• Virtual machine monitor problems

  Hello

  I just installed VM because we want to monitor and confiure our IDS using this.

  I installed it the "Cisco Correct way" which puts the monitor on a server and the Consol of Managament IDS on the other.

  I added manually in all sensors in the management console, but when I look at the monitor-> device status, all 76 sensors I've added it says its 'not connected '.

  I used the option that the monitor must pick up the sensor post office protocols.

  I can PIng the sensors, ssh o sensor, etc, etc, etc, but this 'thing' always shows that he is "not connected".

  Where should I start to get out of trouble?

  Thanks a ton

  Mike

  Hi Mike,.

  You got the right answer in your message. The sensors should be referred to the Security Monitor box and not the MC that the events are sent to the SecMon and the post office runs between the sensors and the SecMon.

  Log on to the sensor as root and run sysconfig-sensor, option 6 and enter the details of SecMon for the part ID Manager of this config.

  Thank you

• How to change the network when the virtual machine is connected, in Vmware ESXi with Perl in Linux?

  Hello

  If someone can answer that the way to change the network of a VM with Perl? I would periodically change the network where the virtual machine network adapter is connected.

• problem with mcafee DLP Device control on virtual machines Windows XP

  Hallo,

  We use view ESX 4.1 and 4.5.
  I have the problem that we use DLP 9.1 with EPO 4.5 and have the problem that when we use DLP USB glue with series nummer they do not work through zeroclient on the virtual machine.

  We've set the rules in the operative part of DLP controll that she is allowed to use usb sticks which are content encrypted and where the serial number is saved in the DLP.

  
  It works fine on normal physical laptop but if I use the same USB on my zeroclient who got a machine virtual vmware as the stick got allways blocked.
  I also tried to register before the stick no serialnumber and used the VID and PID, but also that have the same result as the stick has blocked.

  
  If I disable all the rules of control of the aircraft as the stick got mapped from zeroclient to the virtual machine without problem.
  Can help you to use or is there any practice well known for using control of the device with virtual machines?

  I was also in touch with mcafee, but they want to say, this problem is related to vmware and I close go in contact with vmware.
  
  Best regards
  Heinze MS

  Hallo,

  so, we found the problem.

  The reason why in the virtual machine, it has no SN the stick that we couldn't resolve, but we are in contact with the zeroclient of the teradici seller.

  The reason why the instance id of the stick and PID or VID where does not have a problem in the permission set for the users who have applied the policy of the EPO.

  DLP policy showed he applied rules and also the show later when you loggon, but he was right on the configuration screen that this rule are configuried when you use DLP political configuration of the importation of the EPO server it load the config which is really being used and so we saw that when we have configured the USB via the instance VID PID or device that was never written on the server EPO and never applied to the virtual machine :-)

  best regards, perhaps it's useful for someone

• Question on networks of Virtual Machine

  I have a host machine running Windows 7. I installed VMware player and I create a virtual computer running Oracle Enterprise Linux 5.5 (almost identical to the version 5.5 of Red Hat). In the end I will be installing an application on the virtual machine that is not compatible with DHCP. So, when I install OEL 5.5 I need to manually provide information from network devices (IP address, primary DNS, subnet mask and host name). I've done it before on successfully on a material physical but never before on a virtual machine. On my first attempt I was wrong and my web browser running on the virtual machine can connect to the Internet.

  My instructions say "set the gateway information based on the IP Address of the gateway router. I wonder if this is correct in view of the virtual machine.

  On the machine host, when I run the ipconfig command in the DOS window I see a mask of address and the IP subnet for the host, and I see two additional network adapters for VMware (VMnet1 and VMnet8). The three entries (for example, the host VMnet1 and VMnet8) have the same subnet mask value and different IP addresses (first two segments of the IP addresses are the same, third and fourth segments are different).

  My question is, what are VMWare network cards and I have to pay attention to these IP addresses when I manually configure networking on the virtual machine?

  VMware Player provides essentially 3 types of network connections:

  • 'The bridge' - directly connected to your router
  • "Host-Only' (VMnet1) - limited to the host and the virtual machines network
  • "NAT" (VMnet8) - network address translation

  VMnet1 and VMnet8 virtual cards that allow the host to communicate with the virtual machines and vice versa.

  Depending on if your virtual machine should be accessible from other systems, you can consider using (in - and outgoing) Bridged or NAT (outgoing mail). With Bridged networking, addresses are usually provided by your router/DHCP server. For NAT, the address of the gateway/DNS is 192.168.x.2. Since the VMware Server DHCP internal for NAT and Host-Only uses 192.168.x.128... 254 for dynamic addressing, you want to select a static address in the 192.168.x.3... range 127.

  The easiest way to find out how to correctly configure the network, must first set the operating system to DHCP, note gatherings settings and then just choose another IP address when you configure static settings.

  André.
