• ESX keep disconnecting from the vCenter 4

  Hi guys,.

  I have the ESX host couple who kept disconnecting from the vCenter 4 after I added them in there for 1 minute or so.  The vCenter (CORPIT network) and the host ESX (Customer1 network) are separated by two firewalls and NAT IP addresses.  Here are the current firewall rules.  What Miss me?

  CORPIT to CLIENT1

  VC for ESX - open ports (TCP 22, 443, 902, 903) & (UDP, 902, 903)

  Customer1 to CORPIT

  ESX to VC - open ports (TCP 80, 902, 903, 9000-9100, 27000, 27010) & (UDP, 902, 903)

• The best way to solve this problem (internal vCenter, ESX host external)

  The issue is that we have our virtual Center and our production ESX hosts on our internal network. We have another site of emergency in a remote network, but welcomed a public address with a firewall in front of her.  When I add the host of my vCenter she adds in fact very well and works for 1 minute, then disconnects. This is because the heartbeat may not respond to the virtual Center.  The emergency server will be 3 VMS host, 1 e-mail box, 1 website and 1 backup domain controller.  I only know the basics of networking, so I don't know what would be the best idea of tests.

  I will apply to network engineers after that I know that would work well.

  I should create a nat device for the server vCenter and which will resolve the heart beat question

  I should have a set up reverse proxy, then change the esx host and change the internal address of the vCenter to the public address with proxy reverse?

  Should I make the address pool which esx host has (about 10 external and public addresses) available to route between our internal VLAN?

  Y at - it a sugguestion different with a better description would you recommend to solve this problem and better my future goals with the 3 virtual machines, that I intend to host on this server.

  Any advice is welcome.

  Thank you

  Is it possible to Site 2 Site VPN? If Yes, then it would be much less complicated. Put ESX in DMZ with public IPs is not a good idea in terms of security.

• ESXi hosts are disconnected from the vCenter (5.5)

  Hi all

  We have a little problem with our vCenter.

  We have two hosts that are connected to the vCenter, unfortunately, they are listed as disconnected.

  It seems that the problem are the SSL certificates on ESXi hosts that are no longer valid.

  If I replace the old certificates with new ones, that I have to restart the ESXi host, am I right?

  If so, that's the problem.

  We do not use any what automatic vMotion and as long as the hosts are not connected to the vCenter I can't manually, move right?

  Is it possible to connect hosts to vCenter without SSL?

  Sorry for my bad English, I'm not a native speaker.

  See you soon,.

  Johannes

  You need to replace the ESXi host SSL certificates.

  See the Docs for the replacement of ESXi Cert below.

  ttp://www.BlueBox-Web.com/2013/04/18/replace-ESXi-certificate/

  Documentation Centre of vSphere 5.5

  I had regenerate the ESXi 5.5 SSL certificates, which I did without any stop to virtual machines.

  Certificate replacement process can change based on the esxi version.

  According to the Doc, vSphere 6.0 Documentation Centre ESXi6 host must be rebooted to replace certificates.

  Anyway, in current state disconnected, you can try to regenerate the self signed SSL certs, restart management agents and try to reconnect host in vCenter.

  Thank you

• ESXi host running 6 VCSA disconnected from the vCenter

  Hi guys,.

  I have a weird problem with my vCenter build 6. Single cluster of ESXi hosts. Running VCSA 6.0 and 6.0 ESXI. Making a storage of the vCenter vMotion initially got stuck at 77% and the ESXi host running the disconnected from vCenter vCenter. But I can connect directly to the ESXi host with vsphere client and see the vCenter VM works perfectly well. If I try to manually connect host ESXi and vCenter, I get the error "Failed to contact the host specified") both are in the same subnet and VLAN. I can migrate to other virtual machines without problem. I even restarted the host and yet I am not able to connect to vCenter. The host connects to vCenter if I reboot vCenter, but after a few minutes, disconnects again (even if no task does run on this topic.) I have no HA or DRS enabled at this point that I build this new environment and only presented a single LUN as a store of test data to the cluster.

  Any ideas?

  OK, I think I fixed that or have at least a work around. So the underlying question was hiding ID mode/CPU EVC. I'm under the cluster to a level of EVC to reduce until I have migrate workloads from old environment and I think that this created a problem for the unit vCenter. To resolve this problem, I turned off the unit, directly connected to the ESXi host that had the camera running, edited the virtual machine and reset the masking of CPUID. Also, I've hidden the flag NX/XD of the guest. It's temporary (I hope) as once I increase the EVC to the Haswell, I will expose the NX/XD comments and test. For the moment, it is of the workaround I did. It may be of some use to someone.

• 5.5 ESXi hosts disconnection of the vCenter 5.5.0b

  Good evening.  I recently deployed some new hosts HP BL465c G8 running the HP OEM install ESXi 5.5 (not the one just released 02/18) and the two hosts have been disconnect from vCenter four times in the past week.  I can sometimes connect to the host via ILO and restart the vCenter agent, but more often without having to start the host hard.  In addition, one of the VMFS5 content of the data store disappeared and the virtual machines residing on this data store have declined because the hosts could not find the configuration of the virtual machine files. Strangely enough, the data store showed spaced used and I could see all the directories within the CLI, but not vCenter client or Web-based Client.  I have two tickets to windows with VMware from HP support team, but I wanted to know if someone had a similar problem.  I'm tempted to rebuild with the latest OEM installation or rebuild as 5.1 or 5.0 if version 5.5 is not fully cooked.  Thank you.

  Scott

  The issue proved to be the OEM HP install and specifically the pilot v1.1.7 for HBA QMH2572 adapters that it contains.  We have rebuilt our 5.5 ESXi hosts using installation OEM HP published 02/14 (contains recommendations
  v1.1.12 pilot) and that solved the problem of stability.

• Mobile to a new server vCenter ESX host

  Hello.

  For several reasons (including the old server vCenter 2003 x 86) I would like to move our ESX host to a new server vCenter (version 4.1 under Windows 2008 R2). Our ESX environment using HA/DRS and resource pools.

  Is it possible to move the hosts to the new server without VM downtime?

  I think disabling HA/DRS and then disconnect the old vCenter servers, then adding them to the new. That would be possible, or is there a better way?

  And second, that things are lost that kind of operation? Data of performance and resources with Betclic, another?

  / Christian

  Hey there,

  The procedure is very simple:

  -Disable HA host monitoring

  -Disconnect the old vCenter host

  -Remove old vCenter host

  -Add the host to the new vCenter Server

  -You will be weather you are prompted to add all of the resources of the host with Betclic under a live of... the list resources or put all your VMS in pool root of the pole. Select them grafted in... so you can keep your resource pools. You can move the autour pools in the hierarchy on the new vCenter.

  -After you have moved all of your hosts, you can activate HA host followed once again and check that the DRS has the settings you want.

  You lose well obviously all performance data, but you can bring your pools of resources for the new vCenter.

• ESXi disconnects from the vCenter

  Hello VMware,

  I have some problems with ESXi 4.1.0 (Build 260247) disconnect vCenter. I am currently evaluating Vmware View. I have no problem connecting to an ESX host to vcenter. When connecting vCenter ESXi host host will connect for about a minute and then disconnect. VCenter, Active Directory, DNS, DHCP, and ESXi host is all on the same network without any firewall between the two.

  I have an I tried by using the knowledge base article titled "Diagnose an ESX Server that is offline or does not respond in VirtualCenter" without success. I can connect the ESXi host with ssh and ping various servers on the network using dns and ip addresses.

  Is attached a copy of the message, pass and vxpa journal of the ESXi host.

  Any help would be greatly appreciated .

  Since the log files, it seems that you use vServers 4.0.

  Section for VMware VirtualCenter Agent, pid = 56646, version 4.0.0 build = build-208111 =, = exit option

  The host ESX (i) 4.1 require vCenter Server 4.1, this is why you must upgrade to vCenter Server to make it work.

• Determine the vCenter management host

  Is it possible with PowerCLI / PowerShell to query a host and have it return the address IP (or name) of the vCenter which is manageing that host?

  version 5.0 of vCenter

  ESX (i) version 5.0

  PowerCLI version 5

  Thank you

  Hello, DrewK201110141-

  I think that you are looking for the ManagementServerIp of the ESXi host object property.  By the API to this hyperlink reference, this property contains the 'IP address of the VirtualCenter Server manage this host, if necessary'.  A couple of other responses here were heading to the server to which you connected with your session PowerCLI, but you want the vCenter server, which currently manages the host gave (as appropriate), it seems.  If so, you should be able to get this type:

  ## get the management server IP info (if any) hostsystemsGet-View -ViewType HostSystem -Property Name,Summary.ManagementServerIp | Select Name, @{n="MgmtVCenterIP"; e={$_.Summary.ManagementServerIP}}
  

  The output should be something like:

  Name        MgmtVCenterIP
  ----        -------------
  myESXiHost  192.0.0.31
  

  If you are connected to a vCenter server, which should return the info for all HostSystems said in the that vCenter inventory.  Or, if you're connected directly to a host, it will be back to the host only one information.  How do I?

• limit in el vcenter esx host

  Hola

  I have understood that in el of hyper-v in SCVMM-System Center virtual machine microsoft Manager su (similar a virtual centre), admite UN maximo 400 of the hyper-v host y 8000 maquinas office.

  grabaciones vmware cuanto are?

  Y por otra parte... ¿a what debe esa limitacion host?, bueno, so son 400 también en vmware... aunque como are suficiente.

  In the case of that vmware had una limitacion Mayor en el esx in el host cluster number... (he heard 20), seria a problema para vdi, ch. uando hay gente as necesitaria muchos host (example suppliers of services, telefonica...), in the case of the ultima version of vcenter, podemos 'linkar"varios vcenter y gestionarlos eso esta, pero hay if a cada vcenter tendriamos that tener varios vcenter do not limit?

  Gracias

  Hola Akumal. Yes, you can add a cluster al vCenter mas. En mi caso tengo mas 6.

  Por otra parte tool virtual Mirosoft can administrar tambien ESX, por maquinas SCVMM Center system if you want to have in a single console, toda infrastructure virtual centralizada (Hyper-V is VMWare).

• In vMotion which files moves the destination ESX host?

  VMware dear Experts,

  Virtual computer on a shared storage shops, while moving the virtual machine from one ESX host to another, I want to know that VM all files are moved to the destination host ESX, once the vmotioned process is complete.

  Concerning

  Mr. VMware.

  Some files are moved with vmotion - the content of the memory VM is moved from an ESXi host to another - the files do not change. If you are talking about storage vmotion where the files that make up a virtual machine are moved to another data store while the VM is running - the VMDK files are copied first.

• installation of MSCS on the single ESX host

  Hello

  I've seen a few question running MSCS on the ESX host.  I have a pair of MSCS and MSSQL installation running on top.  I am faced with intermittent conflict ip in my cluster node.  Anyone has any experience on this.  Should I apply any configuration to the virtual switch?

  Hello

  Search for IP addresses on two VMs.

  IP address of cluster name

  Public NIC IP addresses and subnet

  Private NIC IP addresses and the subnet (Heartbeat)

  Also fix this problem, disable Heartbeat NIC on two VMS and select heartbeat communication with the public LAN option in MSCS. This helps to isolate the problem.

• Best way to build the same ESX hosts

  Hi, I need to build 4-6 ESX hosts are configured identically. (Same groups of ports, NTP settings etc..) All hosts will use the same brand/model/hardware configuration)

  I think kickstart server and a load of scripts PowerCLI would be the best way to do this, but I don't him did not before.

  Can you recommend the best way to do that, or no matter what links?

  Thanks in advance

  PS. The customer only paid for the license of the company,(not enterprise Plus), so I can't use Host Profiles)

  Are kickstarts way to go.  However, if you have business + licenses you can use the profiles of the host.
