• Impossible to connect to vCenter Server 5.5 using the vSphere Client

  Hello

  
  

  I'm trying to configure VMware Lab home using the link below and I have reached a stage where I need to connect to vCenter Server using the vSphere client.

  
  http://boerlowie.WordPress.com/2011/12/13/building-the-ultimate-vSphere-lab-part-9-ESXi/

  
  

  I installed the package of 5.5 full vCenter server using the simple installation option and it includes vCenter server, single sign - on, Webclient vSphere, vCenter server and vCenter Server inventory service. All the the latter is installed on a virtual machine that is running Windows server 2008 R2 guest OS.

  
  

  Whenever I try to open a session on the vCenter Server uses the vSphere client, one of the following error is displayed.

  
  

  1. you do not have the permissions to connect to the server 'vCenter server IP address.

  2. cannot complete the connection incorrect username or password-, this error is visible when I do not specify domain\username domain user name and simply enter the user name.

  
  

  For the details of the error, please see the screenshots - vSphere_client_1, vSphere_client_2 and vSphere_client_3.

• Unable to connect to esxi using the vsphere client

  Hello friends,

  I need a little help.

  a 2 5.0 esxi host and a vcenter than VM.

  My laboratory worked well for days, but all of a sudden do not know why I am not able to connect to ESXi hosts with vSphere Client.

  Error: The request failed because the remote server has taken too long to respond.

  Call "ServiceInstance.RetrieveContent" to "ServiceInstance' server '192.168.1.101' object failed.

  Yes, I am able to connect to vCenter server, when it is connected to vCenter and open the console of the virtual computer, nothing shows up, it's a black screen, as if the virtual machine is turned off. It is with all the virtual machines on both hosts.

  1. I thought that it might have to do something with vCenter and I tried connecting to Host individually which I wasn't able to.

  After completing a few KBs on vmware and some articles, I checked the status of the firewall on both hosts. (attached screenshot)

  

  Checked if my computer can talk to esxi host on port 80, 443, 902. all ports are accessible.

  Disabled the Symantec endpoint protection and checked. no positive results.

  Finally, I tried the ESXi web navigation browser host http://ESXi-IP-address which redirects me to HTTPS connection with Certificate error, when I continue with the cert error, loading of the URL guard and the host page doesn't appear as it should.

  This questions are on both hosts. :-(

  You guys can point me in the right direction to solve this problem.

  Thank you.

  Finally things started working now.

  The problem was with the configuration of the workstation's NETWORK adapter.

  The link on the NETWORK adapter speed was set to Auto negotiate (default), but the speed was detected as 100 Mbps instead of 1 Gbps and MTU has been set at 9014 which I defined manually long back.

  Things use to operate in this configuration that I have configured hosts with MTU 9000 and cisco SMB switch default Jumbo.

  the LinkSpeed of 100 Mbps is bugging me, after changing to 1 Gbps (manual setting) the card NETWORK has deactivated, and it reminded me to switch!

  So I put the LinkSpeed Auto negotiation, MTU 9014, stop the two hosts, restart the switch. restarted my computer.

  Since it uses for things were in a normal state.

  Even the question of the console (black screen) disappeared. :-)

  It is my first installation of vCenter Server (on Windows Server 2008 R2 Standard 7601 Service Pack 1).

  As Microsoft IIS Web server was already running on this host, I used alternative ports for tomcat services:

• Maximum number of connections to vCenter Server

• Unable to increase drive vCenter Server 5.0 build 455964

  Friends:

  I have a virtual machine with disk 3, 2 of them has the ability to increase space in gray. The last one is the only one that I can change. I am looking for snapshots in snapshot Manager, but the virtual machine has no snapshot. I created and deleted snapshots, consolidate them, without any fortune. I'm looking for some ideas for review in vCenter Server or another component in the equation.

  Best regards!

  Roberto

  According to the newspaper, the virtual machine has 5 virtual disks (3 x IDE and 2xSCSI). Unfortunately the vSphere Client GUI does not increase the IDE drives (no idea why) and you must do it from the command line (vmkfstools - X) or convert (see http://kb.vmware.com/kb/1016192) SCSI drives. No matter what you do, make sure you have a backup in place up-to-date in case something does not work as expected.

• VSphere from VMware vCenter Server Web Access from the Internet

  I tested VMware vSphere (ESX 4) and tried to connect to the internet for the Web Admin Access VM only.  I can connect the vCenter Server (on Windows) http Web Access features and manage the configuration of all virtual machines. But when I try to connect to an actual vm via MKS, I get an error MKS as ' unable to connect to the MKS: unable to connect to the xxx.xxx.xxx.xxx:902 server.»  The xxx.xxx.xxx.xxx is the IP address of the ESX Server HOST and not the Server vCenter (which administers the host).   I have ports 80, 443, 902 and 903, on the firewall, open to point to the server vCenter Server.  When I'm on the LAN, I can do everything without a problem. Its only when I try to connect directly from the internet through our firewall I get the above error.

  Someone at - it suggestions?

  Andrej770,

  vCenter Server transfers you to the ESX host hosting the virtual machine, and the remote console runs on port 902.

  You want to go directly to the ESX host on port 902 through the firewall to connect to the Virtual Machine console.

  You want to see the pages "Guide de Configuration ESX" 146 for more information.

• vCenter Server 5.5 compatibility with vSphere 4 hypervisor

  I recently installed vCenter Server 5.5.0.5201 (with a Standard license valid vCenter) and I am trying to add the hosts to vCenter data center. I can connect successfully to the host but vSphere displays the following error:

  "The host is licensed with vSphere 4 hypervisor. The license of vCenter Server edition doesn't support vSphere 4 hypervisor. »

  Now I found the slot compatibility matrix and there clearly shows that vCenter 5.5 is compatible with all the way back to version 4 for ESXi. I must be missing something, can someone please clarify the question.

  

  I know that vSphere hypervisor and ESXi Server is essentially the same but vSphere hypervisor is the free version, so is there a difference that I know?

  This happens because you are using a free license on the ESXi 4.1 key.

  "The host is licensed with vSphere 4 hypervisor" means that it is a free ESXi. You will not be able to manage the free ESXi with vCenter.
