• 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,

• 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:

• A virtual machine has connectivity problems

  Hello

  I have a server ESXi 4.1 on it with three virtual machines.  For purposes of discussion, I'll call them VM1 and VM2, VM3.  They are all on the same ESX switch.

  This server has a financial application on VM1 and this configuration worked well for about a year.  Then, all of a sudden this week after users began to have popups while their financial applications, say things like other tables running could not access or that they could not communicate with SQL Server, etc. As far as I know, nothing new got installed, etc. this week on this server.

  I discovered that when I PING another post from work or another physical server for VM1, it loses a lot of PING packages.  There could be 20 consecutive PING responds and then five PINGs that do not meet but no defined trend.  However, when I PING VM2 and VM3 from these other workstations or other servers, they have no problems with PING.  I did PING extended for 10 to 15 minutes and only VM1 continues to have problems with PINGs.  It is not only a problem of PING as users are getting disconnected from their financial app and I can't connect to VM1 using RDP, etc.when happening.  Then, no doubt VM1 connectivity is lost intermittently.

  When I PING the VM2, VM3 to VM1, no PINGs are lost.

  The physical server that hosts ESXi 4.1 has two network adapters integrated but alone is used now.  Thus, all virtual machines are physically connected to the local network through a NIC

  We have a new Ethernet switch so I temporarily moved the LAN cable connected to the ESXi server to a port on the switch again and looks that much worse.  And again single VM1 lost PINGs.  VM3 and VM2 were very good.  I put the LAN cable to the original switch port and it seems that it is better but worse that before install me the LAN cable.

  If anyone can give me advice on how to solve this problem, I would appreciate it a lot.

  Thank you very much for your help.

  Off you first need to understand what is happening... You need to isolate what is a VMWARE problem, a server or network problem.

  I would start by ping from machine VM-virtual... In this way you take all opportunities that all physical connections are stop things from work.

  NM, you have already done this... Its good

  Which means that ICMP queries are good in the VSwitch. Internal network traffic so can't see any problems.

  So the problem is most likely will lie about how your traffic destined to this server is routed to this server.

  I would start by

  DNS. Check and see that your DNS is working properly and that all your zones are registered. Flush DNS on servers and workstations.

  Also try to reconfigure the VMswitch or linking this server for the spare VMnic if you can to see if it clears up your problem. Also try turning off the firewall as mentioned above...

  But first of all to identify the problem and were breaking is Lyon. Good luck

• Help to get a list of virtual machines with switch network and name

  I'm trying to get a simple list of virtual machines on a single host and include their name and networkname.

  When I run this Get - vm | where {$_.} $host.name - eq "ESX.local"}, I get the virtual machines with their name.  When I run this Get-networkadapter - vm Get - vm | where {$_.} $host.name - eq "ESX.local"} I download news network with the name of the network, which is what im after. "  I want to combine these 2 commands and get vm name and network name in a csv.  The network name is the Group of ports, the VM is affected change settings for example, it could be vlan10 or what you named your group of ports in the switch DV.  I've attached a screenshot of the orders successfully.

  Hello, brisketx-

  You could do a little more efficiently by getting first the VMHost (s) that are of interest, then get their virtual machines and then using a computed property for the names of network for virtual machines.  As:

  Get-VMHost esx.local | Get-VM |    Select-Object Name, @{n="NetworkName"; e={(Get-NetworkAdapter -VM $_ | %{$_.NetworkName}) -join ","}}
  

  You can then, of course, lead to Export-Csv to write the data to a CSV file.  How does do for you?

• 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

• PowerCLi script to check if 2 virtual machines are on the same host

  Hello

  I'm nubby on PowerCLI and I would like to help in the construction of a script.

  The script should check if two virtual machines (named test1 and test2) are running on the same host in a vCenter and send a notification (email), if they do.

  Something similar with affinity / anti-affinite DRS rules (but not through the DRS enabled on vCenter).  My focus is on the affinity. In case this happens, I need vMotion one of them on an another ESXi host(manually or automated).

  What I have done until now is the following:

  Get - VM | Select Name, @{N = 'Cluster'; {E = {Get-Cluster - VM $_}}, '

  @{N = "ESX host"; {E = {Get-VMHost - VM $_}}, '

  @{N = 'vCenter'; E={$_. "(ExtensionData.CLient.ServiceUrl.Split('/') [2]}}, '"

  @{N = "Datastore"; {E = {Get-Datastore - VM $_}} | `

  Export-Csv - NoTypeInformation C:\Scripts\file.csv

  That becomes all the VMS and export a CSV file information:

  Name	Cluster	ESX host	vCenter	Data store
  test2	cluster_test	ESXi_test1	vCenter_test1:443	datastore1
  Test1	cluster_test	ESXi_test1	vCenter_test1:443	datastore1
  For1.local	cluster_test	ESXi_test1	vCenter_test1:443	datastore1
  VM1.local	cluster_test2	ESXi_test2	vCenter_test1:443	datastore1
  VM2.local	cluster_test3	ESXi_test3	vCenter_test1:443	datastore1
  VM31.local	cluster_test3	ESXi_test3	vCenter_test1:443	datastore1

  Thank you.

  Try like this.

  $tgtVM = "test1", "test2".

  Get-VM-name $tgtVM | Group-object - property VMHost | %{

  if($_.) County - gt 1) {}

  $vm = $_. Group | Get-Random

  $esx = $vm. VMHost

  $tgtEsx = get-Cluster - $vm VM | Get-VMHost | where {$_.} Name - not $esx. Name} | Get-Random

  Move-VM - $vm - Destination $tgtEsx VM - confirm: $false

  }

  }

• 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!

  Concerning

• 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.

• is it possible to access the virtual machine when the network is down...

  Hello. He... IAM wondering is it possible that we can access the virtual machine when the network is down... (Because of power outages or when the fluctuations...) ................?

  Is it possible that I can configure my Virtual Machine...?

  Thank you and best regards...

  Indianmale...

  Hello

  Not really...

  For an environment hosted... If you can access the console of the host, you can always access the console of the virtual machine regardless of the State of the network outside of the console. VMware Workstation, Fusion and server all fall into this category.

  For ESXi/ESX... you need a host outside to access the console of the virtual machine. ESX and ESXi not displayed graphics or VMs of their consoles and management devices. So, you need an external machine that can run the vSphere Client or access to the virtual machine via RDP, VNC according to Guest OS involved or SSH.

• Working in a virtual machine of shared folders and not another...

  Hi, I'm new to the community but have worked with VMWare Workstation for about 9 months now. I have a set of 5 VM that I run on a regular basis, and I had successfully implemented the shared folders in each VM to a central folder on my C: drive host. I now have new versions of several of the virtual machine and I am trying to configure access to the same shared folder, but it will not be displayed.

  After you set up the information in shared folders in the virtual machine settings, I go into the virtual machine on my computer and expect to see under readers network, "Shared Folders on .host '. Who does not appear and when I try to map a network drive to //.host/Shared files /, it can't find the network.

  I compared the parameters between a virtual machine that has the Shared folder working and one who does not work, and I can't seem to find any differences.

  Here are some of my system details, if it helps:

  VMWare Workstation Version 6.5.2 build 156735

  Host of OS = Windows Server 2008 (64-bit)

  VM OS = Windows Server 2003 (32-bit)

  I've updated the VMWare tools in the virtual machine

  I have ideas of what I can try to get this working. Thank you!

  Try to upgrade the virtual hardware version 7 - maybe it does.

  Why don't you use the entries for the disks in cluster? -of course, you know that they are not stable in WS 6.5
