• Migration to new server vCenter ESX continuously.

  What would be the recommended steps to migrate seamlessly from one ESX host to a new vCenter Server?  I succumbed to find any documentation on this.  For some reason any I think remember me that with a previous version of Virtual Center (1.x and 2.x) that the host had to be in maintenance mode before it could be removed from the management server.

  I need to move the ESX 3.5 and 4.0 hosts to a new management 4.0.1 vCenter server.

  You can simply disconnect and remove the host.  Then add the host in the new environment. This will affect any of your guests running. If your VI3 hosts, make sure that you have the available license server.

• Migrate to the new server vCenter hw

  I make plans to migrate all my my old hardware of server vCenter ESX hosts to a new (and much faster). Both vCenter servers are version 4. To delete a my old vCenter ESX host, I need to put it in maintenance mode. Maintenance mode means turn it off or by moving my VMs to other hosts.

  Is there a way to move my ESX hosts to the new server vCenter without voltage VM?

  Hi bjornl,

  If you need to keep the virtual machines running on the host computers, while removing a cluster host, data center or same vCenter, and then select the option 'Disconnect' first. The host shows as grayed out and disconnected. Once in this state you can 'remove' the host of your first vCenter.

  Create your new data center and then "Add host" Cluster in the new. Everything will be powered on your virtual machines.

  The only issues I've had with this is if the original or the new cluster using vMotion improve compatibility (EVC). This aspect must correspond to both ends. Once you do this, it works fine.

  Hope this helps,

• New server vCenter Server

  I am running a 3.5 environment, and I want to get to sphere.

  I'll create a new vSphere vCenter server to manage my boxes of esx 3.5 and possibly update these boxes to sphere.

  Currently, vCenter 3.5 I manage my esx boxes, and this same server is the license server.

  Can I simply create a new server and then add my esx boxes in its inventory of management?

  Do I have to remove these boxes on the other server vCenter esx?

  Can the two vCenters be running at the same time?

  And have point to the new server cVenter to the old server vCenter for licenses, or simply keep the old server up?

  Yes, unplug and remove hosts from the old environment of vCenter and add a host in the new

  Do I have to remove these boxes on the other server vCenter esx?

  Yes

  Can the two vCenters be running at the same time?

  No.... not if they use the same DB instance.  If you use a different instance of DB, then Yes. But you can't manage the same ESX host in both environments.

  And have point to the new server cVenter to the old server vCenter for licenses, or simply keep the old server up?

  You can use your old license for your VI3 hosts server.  Home - vCenter Server Settings.  Or you can install a standalone license server.

• Problem after moving to new server vCenter

  I moved vCenter to a new server by following this article:

  http://KB.VMware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 5850444

  After editing the file vpxa.cfg with the new IP of the vCenter server and restart management services, all of my guests are still disconnected.  I tried to select "Connect" from the menu, which has been connected to the host.  However, HA not properly configures.  Has anyone seen these symptoms after moving to a new server vCenter? Ideas for how I can fix the problems?

  More details can be provided according to the needs

  Thank you

  Jeff

  Is / was enabled on this cluster HA?  Have your tried to disable HA on the cluster, and once that all your hosts have been added to the rear allowing HA again.

  In addition, even if you did, you can restart the agents once again all hosts in the cluster

  > service vmware-vpxa restart

  > service mgmt-vmware restart

• The steps required to perform a migration to a new server vCenter using distributed switches?

  We are currently on version 5.1 of vCenter and ESXi 5.1 on all our guests.  We use a vDS on our current server vCenter and will need to migrate to a new server vCenter soon.  Is there a documentation about the steps to migrate to a new server vCenter using switches distributed?  We hope to achieve this goal without any downtime.  The problem is that we need that VDS on our 10GB network for the aggregation of links.  If having to migrate guests at standard switches before moving them to the new vCenter server, there will be problems of network performance.

  Because information about your environment are stored in the database of vcenter al you should just be able to stand up the new vCenter server and that it points to the existing database

• Built a new server vcenter, simple as moving the hosts?

  Hi, one of my clients is running ESX 3.5 U4 with Virtual Center 2.5 U4. We intend to upgrade their environment to vSphere this weekend. The server vcenter 2.5 right now is running underpowered, so they decided to deploy vcenter 4 on a new, more powerful box rather than upgrade existing installation. I built the server and installed vcenter 4 using their license key. My plan for this weekend seems simple enough, but I couldn't find this specific scenario anywhere in the guide of upgrade provided by vmware, so I thought I just would make sure:

  1. disable HA and DRS on current ESX cluster

  2. Unplug each host in turn of the bunch. (leave the cluster running in case of a need to roll back)

  3. Add each host in turn to a newly created on the new vcenter server cluster 4.

  4. turn on the DRS and HA services on cluster vcenter 4

  5. use of the upgrade Manager to upgrade each host ESX 4.

  Am I missing something? Thank you.

  After correcting the ESX host, address to Virtual Machines

  Addressing guests ESX with Update Manager summary

  In the Update Manager, create a database upgrade ESX host

  On the References tab and select groups, upgrade of the baselines, click on create in the upper right corner

  Name: ESX 4.0

  Base Type: upgrade host

  ESX upgrade iso: Browse for downloaded ESX 4.0 ISO

  Set this line of base to your hosts

  Scan of hosts against the base line

  Tackle the hosts against base - * Note that Update Manager controls the application of the ISO you have downloaded and created a basic manual for running the ESX upgrade.  Update Manager is no longer just for the patches.

  Address to virtual machines

  Select the tab 'reference levels and groups '.

  Select view planning for: VMs/SAV

  Under groups, select Create

  The database name: VM Upgrade vSphere hardware and tools

  In the new Group Wizard, select "Updates"

  Select "VM Hardware to match the host"

  Select "VMware Tools upgrade to host of the Match"

  Come on in "inventory - models and virtual computers ' view

  The leveling refers to virtual machines, you want to update - may fix the object data center level to apply to all virtual machines

  Scan for update - can do on the subject of data center to all virtual machines at the same time

  Clean up - can select a subfolder or individual to run VMs update process gradually

• Disconnection of the VCenter ESX host

  Hi, I was wondering if anyone else has had this problem.  I have an installation of VMWare VCenter and 4.1 ESX servers.  Periodically, one of my ESX hosts will lose just login to the VCenter server and I need to re-add.  The host still pings, does not actually lose network connectivity or I receive an alert.  I've been searching newspapers with no luck yet.  Any help would be appreciated.

  Thank you

  good things!  Glad to see you go it is resolved

• 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.

• Changing the DNS server for ESX hosts?

  Our network administrator will change the IP address of the DNS server.  In this way, we will change those corresponding to ESX hosts.

  We would like to know

  (1) can we change the DNS server on execution of the ESX hosts without going into maintenance mode?

  (2) under what circumstances the ESX host will do use DNS servers?

  (3) memory, we should add all the IP addresses of ESX host in the hosts file in the Service Console, where is this hosts file located at?

  Thank you

  Tony,

  Use "service network restart" command to restart the network service

  Do not forget also that...

  Very dependent on DNS HA, HA will not work without the correct DNS configuration. The servers ESX and vCenter server must be able to resolve the name (FQDN full) / IPs in both feel to get a working HA.

• Problems of acceso a 3.5.0,123630 desde vCenter esx host

  Hola a todos,

  No Sabia muy although in el asunto poner para explain el problema, pero el caso are that I have a stupid esx the version3.5.0, al 123630 than esta Mañana misteriosamente desde el vCenter no podia (indicaba than no respondia) pero connect las vm seguian running sin problemas. Intentando access vCenter o al well al don't host directly, en ambos casos indicaba than no respondia.

  Hemos las paradox VM y posteriormente el host reiniciando y todo ha funcionado correctamente. M'imagino el problema are el servicio del vCenter o no se. He mirado los do logs y no hemos visto nada raro (well not miramos los connects correctos o no is detalla el problema).

  Alguna idea?

  Gracias

  ESO pasa porque el SC the llena, o algun problema acceso muy mmeoria con esta nightclub. Hay algun agent of material are in service el monitoreo console?

  Igualmente, you sugiero deshabilitar el CIM server desde el Configuration > settings advanced y monitorear Server para ver el if no pasa mas el problema.

• Desconectado del VCenter ESX host y no will can volver a connect

  Hola

  Tengo an ESX than estaba tan tranquilo, running sin problemas y of repent al registarle una VM in el inventario...-> disconnected pufff.

  Las maquians not be han visto afectadas, y los users follow trabajando.

  Tengo acceso por PuTTY y por VIC directo al ESX, pero no puedo anadirlo (connect o anadirlo) al VCenter: "unable to communicate with the host specified. Maybe it's because the host is not available on the network, there is a problem with the network configuration or management on the host services do not react"

  He intentado:

  REINICIAR el vmware go: restarting the service mgmt-vmware-> nada

  REINICIAR el vpxa: restarting the service vmware-vpxa-> nada

  He even eliminado officer el para lo nuevo instalara-> nada

  Los connects without any error desagradavel muestran.

  Tengo espacio in las particiones

  No hay any core dump reciente.

  Alguien tiene alguna idea of as mirar mas? No quiero tener as plan una parada 20 maquinas para reiniciar el ESX

  Saludos

  If upon esta u otras answer useful, por favor considered el puntos seleccionando respuesta correcta o util como asignar

  If you find this or any other answer useful please consider giving points by checking the answer useful or appropriate.

  A¿te el acceso al host directly desde el VIC works? ES decir, al access ESX, utilizando el VIC y usuario/contrasena root.

  The case of ese, that agregado al inventario a VM exist? In ese caso, brought desregistrarla y desde el VIC apuntando el contra VirtualCenter, brought reconectar el host...

• 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).

• Migration 4 and 3.5 ESX hosts again vCenter Server 4.0

  I'll put up a new vCenter Server 4.0 with an Oracle database to take the place of two vCenter using express databases included. They are both on the hosts recommended 5-50 VM for the Express database, oops.

  The first is vCenter 4.0 which uses the express database included is on a Dell 1950 server. ESX 4.0 hosts are on 2 groups on Dell blade servers that have 5 blades per cluster and are using storage arrays EqualLogic iSCSI for data warehouses. More there are a few individual Dell R900 and Dell R710 servers use local storage connected to the vCenter.

  The second is vCenter 2.5 that uses the express database included running on a Dell 2950 server with, like 20 other Dell running ESX 3.5 of 2950 using local storage.

  Looking for a vision a little and advise the host migration to the new server vCenter Server.

  Thank you... Jim Hurley

  I would say the easiest would be to create new vCenter new host OS (I would choose 64 bits that will put you in the conditions required for 4.1).  Once the new vCenter Server online, I then install a standalone license server for your VI3 hosts, then begin to disconnect and remove other environments and new hosts.

  Stand alone license server can be found
