Speed limit of the network in the Virtual Machine

• Is there a speed limit on the ethernet cards?

  Hey guys do you have an idea who is at - it a speed limit on the Ethernet cards, because I can use the P2P so fast that, after awhile, my internet connection is stopped as, I can't do anything unless I unplug, wait a while and connect again. Don't you think that it is a hardware or software problem?
  By the way: my Ethernet card is Marvell Yukon 88E8036 PCI-E Fast Ethernet Controller.
  I need your help. Thank you.

  Hello

  In my opinion, if you have some problems with the internet connection the reason should not be any kind of speed limit but also other different reasons.

  In your ad, you're not mentioned that you do exactly. You write e-mails or do the download of two different movies and many mp3 files?

  As far as I know if you do the full download the connection can be slowed or even stopped by FAI. Is your cable may be defective. The LAN cable has 8 lines and if one line is faulty speed will fall automatically.

  I also recommend you use a malware scanner and check the unit.

  Good bye

• 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!!!

• 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.

  Thank you

  Take a look at the vGhetto repository of scripts, where you can find a lot of useful scripts, including updateVMPortgroup.pl , which may contain what you are looking for.

• How do I create standard vSwitches in a HA cluster where the virtual machine switches to the same network?

  I have a lab put in place with 2 hosts 5.5 ESXi and vCenter.  I want to create a situation where each virtual machine must have a dedicated network card.  If I create vSwitchABC on host 1, what should I do on host 2?  Create vSwitchABC on that host too and connect it to the same physical switch?  Which will allow the host 1 failure and the virtual machine to arrive on host 2 on the network because the same vSwitch names?

  Thank you!

  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

• VMware networking help - network bridge / to access the virtual machines form other pc

  I have a computer 'server' that had 4 VM launched on it.

  I need to connect to these virtual machines, all of which have their own IP addresses. I can ping the server or the host of a remote computer, but must be able to communicate with the virtual machines in the remote/client computerss.

  Can anyone offer insight?  I tried to set up an automatic bypass at one of the virtual machines

  Any thoughts?

  Sorry, I'm not sure I can follow you. In any case, what you're trying to do is to configure adaper network of the virtual machine as "Bridged" within the parameters of the virtual machine and then change network card settings in as guest OS:

  IP address: 192.168.1.21 (where 21 must be an unused IP address currently)
  Subnet mask: 255.255.255.0
  Def gateway: 192.168.1.1

  Preferred DNS server: 192.168.1.1

• Average throughput of the network to a virtual machine with PowerCLI

  I would get average network throughput for a virtual machine with PowerCLI including all e-cards, the virtual machine has for the last week (not including NFS or storage of traffic-related).

  How best should add this report:

  Get - vm myvm | Select name, numcpu

  Thank you!

  Try like this

  Get-VM | Select Name, @{N="Avg Network Throughput MBPs";E={    [math]::Round((Get-Stat -Entity $_ -Start (Get-Date).AddDays(-7) -Stat "net.throughput.usage.average" |    where {$_.Instance -eq ""} |    Measure-Object -Property Value -Average | Select -ExpandProperty Average)/1KB,2)}}
  

  The script takes the aggregate value for all NICs for (the one where the Instance is an empty string).

  Then we take the average and converts the Kbps, Mbps.

• Access to the network in all virtual machines lost after that put 8.1 to level.

  Today, I upgraded my host computer to Windows 64-bit Pro 8.1. I did the upgrade through the Windows store. There are no errors or problems during the upgrade.

  However: The host machine equipped with a Qualcomm E2200 network adapter, and it runs the 'Killer' Network Manager software called at startup. After the 8.1 update, when the machine did its last restart, Qualcomm Network Manager opened with a message that the LSP has not mapped correctly. I clicked 'YES' to remap it. Probably a stupid move on my part.

  Thereafter, I lost all network connectivity in all my virtual machines. I have virtual machines for Windows 8, Windows 8.1 RTM (not the preview) and Ubuntu 12.04 LTS. ALL of them have lost the network.

  The host computer has no network problem and works well after the upgrade.

  Any ideas or suggestions to reset network connections in virtual machines?

  All virtual machines are set to use NAT.

  Oh I have to say also that the host computer is running VMware Workstation 10 and everything was fine and dandy, has never had problems at all until this upgrade/LSP remap thing. I have install VMware Tools in the VM of Windows 8.1, with no effect at all.

  Thank you.

  Two things, I'll try:

  1. go in the virtual network editor and restore settings. The culprit is probably the VMNet to NAT configuration.

  2. If this does not work, it seems that the virtual card for NAT does not somehow. The simplest workaround is to uninstall and reinstall the workstation.

• Network problem in the virtual machines on the same switch

  Hello

  I'm stuck on a problem with my small network.  I have an ESXi 5 host that hosts around 10 virtual machines.  The last two machines I install recently displayed an unexpected behavior.  I can't do a ping between the two machines or in those 2 VMS to anywhere else in the same subnet or other networks.  These two VMS, I am able to ping and have network connectivity.  Two of these virtual machines reside on the same vSwitch and belong to the same group of port as other machines.

  The configuration of these two VMs appears to be identical to all other virtual machines that work properly.  The two guest virtual machines running Windows Server 2008 R2.

  So far, I tried several static IP and DHCP assignments with the same effect.  (Including spend another virtual machine a static IP at work known to one of the computers virtual problem)  I tried to delete and re-create one of the virtual machines completely.  I also did an upgrade from 5.0 to 5.1 for vCenter, ESXi host and virtual machines, and I am always observing the same behavior.

  Any advice on what to check next would be greatly appreciated.  Thanks in advance.

  I assumed that you have checked the windows firewall? Because they block default ping...

• 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.

• The two showup labels network in the virtual machine Summary tab

  I changed the port group to a virtual machine from XYZ to ABC. Everything works well, the server pings. But in the Summary tab, I see the XYZ portgroup and group of ports of ABC. Network port group in Edit setttings show correctly.

  When I changed the port Summary tab group should appear the new port ideally group but its showing two groups of ports. Why is this happening? Any ideas?

  Varun-

  Search the clichés about the virtual machine! If having an old cliché of the old portgroup remains in the summary.

• How to access the virtual machines to different physical network?

  Hello

  I'm new to ESXi, can someone tell me how can I access virtual machines on the physical network existing in case I use different IP classes? Physics of the network by using the class C IPs and I assigned IPs to virtual machines of class A? If it is possible, then, what are the steps?

  In fact, I installed exchange 2010 VMs and also want to access the email accounts of physical network.

  Thank you.

  You mean there's no way in ESXi to configure the way so we can access the virtual machines to physical network? without third-party applications.

  Because it is impossible for the various networks IP connect without a router, you must have such a device. There is really no difference in that in a pure virtual or physical environment.

  You might think the ESXi host as a box with one or more servers (virtual) inside and one or more layer (virtual) two switches, just like a small server room. This means you will need to provide the same type of connectivity that you would have to a new server room with machines configured with addresses in a different IP network range.

• 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.

• 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.

• No network on the virtual machine after the use of converter

  I was running a basic vm (WinXP) on an esxi4.1 host running short of disk space.

  So I ran the vCenter Converter Standalone client to copy the original VM on a new - the only thing that I changed the size of the disc thin provisioned avaiable.   The copy/convert seemed to work your.

  I started in the new virtual machine, and it came exactly as the old one (with the largest disk).

  ... but the network on the works of more than vm.

  I can still use vSphere to connect to the esxi server and bring up the VM console (which tells me that the network the server works very well).  When I look at the configuration of the virtual machine, it looks exactly like the old (complete with a network powered).   But on the virtual machine, I can't even ping the router, much less get to the dhcp server.

  I even went so far as to stop the virtual machine, remove the network card, restart the virtual machine (if the network has been removed from the virtual machine), stop the virtual machine again, add a NEW network adapter.

  Still the problem remains.  The virtual machine has a network card - but has no network.

  A few thoughts:

  You use a managed physical switch? If so, check if the MAC address of the VM is seen on one of the uplink ports.

  The network management and the virtual machine using the same IP subnet? You could probably try (if possible) is to create an another vSwitch and attach the XP VM to it to see if there is a problem with the virtual machine and the management on the same vSwitch network.

• 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

  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.
