A virtual machine has connectivity problems

• Check if a virtual machine has connected network and connect if it isn't?

  Thus, creating a big deployment VM automation workflow, I need a way to check and make sure that the deployed virtual computer has its connected network. However, I can't seem to find a way to generate scripts which correctly. Any ideas?

  Hello

  There are different strategies. Look at the 'vim3waitDNSNameInTools' action, it waits until the virtual machine arrives with a given host name. Which ensures that this customization is done completely.

  Alternatively you can ping the virtual computer by using the System.isHostReachable () method, find an example here: Ping on the workflow server

  (I remember there were some problems with this method in previous versions, be sure to properly test ;-))

  Another strategy might be to use the operations of comments and call a ping of in the guest operating system (with which you shall vro network connection to the virtual machine itself, you can for example leave the guest operating system ping the address of the gateway or so)

• 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.

• How to check if a virtual machine has active hotplug?

  Hello

  I am trying to create a workflow that is supposed to change the amount of vCPUs and memory on a virtual computer.

  (for those who arrive suspicious: I'm continuing / edition work of Munel, another user here)

  Since we have different types of VMS, I need to check if a virtual machine is capable of hotplugging processors and memory.

  Now the workflow is designed in a way, it first tries to change the values, and if it runs into an error, it checks if the error code says that the vhardware is not active hotplug then stop the virtual machine or throws an exception.

  This is not a very nice solution and must be changed.

  Is there a way to check the ability before hotplug actually trying to change the vhardware?

  Thanks in advance

  Andreas

  Hi Andreas,

  To check if a virtual machine has a hot connection activated, you have the following options:

  Check if memory hot add is enabled:

  virtual_machine_instance.config.memoryHotAddEnabled

  Check if the CPU hot add is enabled

  virtual_machine_instance.config.cpuHotAddEnabled

  Check if the hot removal of CPU is enabled

  virtual_machine_instance.config.cpuHotRemoveEnabled

  If you have the vSphere client, tree options above are located in the Configuration dialog box of the virtual machine on the tab Options-> memory/CPU hotplug.

  Hope this helps,

• Virtual machine has 8 virtual processors, but the host only supports 4... ?

  Hello

  My setup is a VSphere cluster with 4 guests each with:

  E5450 3.00 Ghz Dual Xeon Quad & 32 GB of Ram.

  I run a number of virtual machines, mainly Windows 2003 Server Enterprise. Most of them is running on 2 or 4 virtual processors.

  I tried to create a new virtual machine with virtual cpu 6 or 8 and 16 GB of ram. When I tried to turn on the virtual machine, I got the message below:

  Virtual machine has 8 virtual processors, but the host supports only 4. The number of virtual processors can be limited by the OS, etc...

  Now, I checked my licenses and they are for each host that I have:

  Company of VSphere 4. 1-6 cores per processor. 2 cpu by assigned host.

  Thus, it cannot be a problem with the license...

  Any ideas?

  Hello and welcome to the forums.

  The Enterprise Plus edition is required for vSMP 8 channels.  You can check in the vSphere editions comparison.  The Enterprise edition will be limited to 4 vCPUs.

  The 6 cores per processor refers to the ESX host itself and directly relate to the SMP virtual machine.

  Good luck!

• vROPs - you can create a report to show when a virtual machine has changed and what has changed?

  I can't currently developing a report/view that can show me what I'm looking for.  I thought since it's related capabilities vROPs can keep track.  Is there a way to see the when a virtual machine has changed and what has changed?  Looking mainly vdisk, vCPU or vRAM.

  Thanks for help or suggestions.

  Hi newbski1,

  There are few things you can try to help him with this.

  1. the events view shows you changes in resources, it is not terribly detailed, but it will help

  2. depending on your version, you can also view in Configuration Manager that is part of the vRO suite that will show you the changes to configurations.

  See you soon

• virtual machine cannot start, because the snapshot of the virtual machine has been deleted by mistake.

  virtual machine cannot start, because the snapshot of the virtual machine has been deleted by mistake.

  When I start this virtual machine, it prompts: unable to find the 0001.vmdk, this disc is my shot, has been deleted by mistake.

  How to restore this virtual machine.

  You need help with a revival of the 000001.vmdk deleted or do you want to repair the virtual machine so that it works without the snapshot?

  The last option, follow these steps:
  remove the virtual machine from the inventory and edit the vmx file so that it uses the basedisk. Then add the virtual machine to inventory.
  If you need data from the snapshot call me through Skype "sanbarrow" - I may be able to help

• Virtual machine has 12 virtual processors, but the host only supports 8?

  Hi all I am using ESX 5.1 and have a machine Windows 2012 R2 Standard of virtual (vmx-09) comments that I'm moving to 8 processors to 12 processors.  But when I turn on the virtual machine after changing the UC 12 I get the error message

  "Virtual Machine has 12 virtual processors, but the host only supports 8. The number of virtual processors can be limited by the selected guest OS for the virtual machine or the granting of licenses for the host".

  Now, I know that 2012 R2 Standard Windows can handle 12 processors and I thought that ESX 5.1 could also, but I'm wrong?  This is the Standard of vSphere license 5.  Thank you!

  Hello

  vSphere 5.1 Standard license has a 8 vCPU per VM limit.

  Company = 32 vCPU

  Business + 64 vCPU

  You must upgrade to vSphere 5.5. This can be done with your vSphere license 5, as it is for all versions 5.X of vSphere and vCPU limit has been deleted in 5.5.

  So you can have as many vCPU per VM that your host has logical cores.

• Impossible to allocate additional processors (virtual machine has 8 virtual processors, but the host only supports 4)

  Dear team,

  I want to devote 8 vcpu to one of the virtual machine, but it gives following error

  "Virtual Machine has 8 virtual processors, but the host supports only 4. The number of virtual processors can be limited by the selected guest OS for the virtual machine or the granting of licenses for the host".

  want to know the weather, that it depends on the os under license or guest vm

  

  Hello

  It is the restriction of license. 4-way vSMP is the right thing, you stressed in your screenshot.

  If you upgrade your server and license to vSphere 5, you can allocate 8 vCPU with Standard license and 32 vCPU with your license of the company!

• Transport mode "nbdssl" is not available if the virtual machine has no snapshot

  When I use VixDiskLib_ConnectEx with a vmdk having a snapshot, I "nbdssl". If the virtual machine has no snapshot, I've always had "nbd" no matter what I specified in the parameter transportModes of the VixDiskLib_ConnectEx. I tried NULL, "nbdssl". It affects always unconditionally "nbd" when there is no snapshot.

  Is this expected behavior? If so, I am not able to write safely to a vmdk. During a recovery, I create a new vm. However, there is no snapshot. I want to get back to this vmdk.  How to work around this limitation of security?

  You use 1.1?  nbdssl restores are not supported on 1.1.

• Have problems connecting to the Internet after the virtual machine has crashed.

  Original title: problems sudden ethernet

  Hello

  I'm having a problem with connecting my computer custom-made. I was with my virtual machine to run an android phone. It connected via a second wireless connection (I don't know much I just let it work). It crashed my computer and when I rebooted I had no internet.

  It would also be useful to mention that I recently had a BSOD because of the virtual Manager and a driver, but I solved it.

  He said that no connection is available, and there is a red cross.

  So far I have tried:

  A second ethernet cable - nothing. (The two wires green on the end of the PC and the end of the router).

  Updated windows, but he can't because of the lack of connection.

  System Restore, but it says "Windows has detected corruption of system files on Local disk (C .)» You should check the drive for errors before you can restore it.

  sfc/scannow, but which translates "could not Windows Resource Protection start the repair service".

  I have also reinstalled the drivers for my cable ethernet twice and nothing.

  If more information is needed please ask. Thanks in advance.

  Hello

  In Device Manager, expand network adapters, right click on the Ethernet device and update the driver.  Otherwise, identify the manufacturer, go to their website and download the latest driver.

• Problems if a virtual machine has 2 records of 2 different tier storage disks

  Hi all

  I think about the possibility of being able to use the cheaper storage by creating a new virtual machine that has a level 3 drive to install the operating system on and a disc of level 2 to hold data to i/o. I have not found anything about it so thought I'd ask here.

  Anyone already done this?

  Can you see a problem doing this, or are there any known issues that I missed?

  Thank you

  Steve

  I have a couple of customers doing this at the moment. They perform their additional disks on a different level. No problem at all, though that doesn't mean you need document your environment very well for possible troubleshooting in the future. (especially when doing the command line stuff that's going to come in handy when you know what / where / when and why.)

• Updated since VM Server-> 2 1 now one of virtual machines has no network connection

  After installation and the upgrade of the vm and vm tools there always no network connectivity. There is an another VM on the host with this particular virtual machine and it works fine. troubled virtual machine, you cannot ping the host machine and the host as well as anything else on the network cannot ping the machine... I have add an another network card deck (primary level is filled with a static IP address) and the second bridged was able to pull an IP address via DHCP, but once again the machine is always not available... any ideas?

  There is probably no firewall clutter it? Can you post ' ipconfig/all' output of a malfunction prompted and the host? You have virtual machines that work ok?

  I saw a problem once, in which case a virtual machine can obtain an IP address from the DHCP server, but later would give "Destination unreachable" for any other than herself ping. Turned out to be a problem with the IPSec service (so a Windows issue rather than an a VMware). See more post on this topic:

• ESXi host have not of virtual machines when connected through vCenter

  Hi all

  I am facing a problem with 1 ESXi hosts. All other hosts are working properly.

  All hosts are managed by vCenter 5.1 VM. When I select this problematic host in vCenter and click on the virtual computers tab, it does not display anything other than a blank page. Then, it throws an error saying that the object has been deleted or has not completely created. The screenshot of the error popup is attached.

  However, if I connect directly to the host through the VI client, it does not throw the error and I can see the virtual machines it. If I have vmotion the vms during this host, I do not see these virtual machines via vcenter but I connect directly to the host and I can see the virtual machines. They work very well.

  What could be the cause of this problem.

  Thank you

  AG

  I would try restart the management agent on the host troubled or removing of vCenter and time.

• convert virtual machine with connected users

  Hello world

  Is is 'OK' to convert a small server terminal server on a virtual machine, while users are connected?

  It does not, as I have done this several times, but wanted to know for sure... what may be the consequences.

  I have more than one terminal Server and I want to keep a virtual copy, just in case tha hardware version breaks, so, I can get users upwards and while work on the virtual version while the equipment is repaired.

  Thank you!!

  Peter

  P2V server will you get at first, then slowly increase on the farm of virtual machines that provide services Terminal Server.   You may want to decommission the p2v version if problems occur.

  Kind regards
