Unable to connect hosts to vCenter

• Connection host to vCenter

  Hello

  I have vCenter 5.1.0 947673 and I have both two ESXi hosts are 5.1.0 version 799733. The first to connect the vCenter with problem but the other gave me an error:

  Failed to contact the specified host (192.168.250.XXX)
  . The host may not be available on the network, a
  network configuration problem may exist, or the
  management on this host services may not be
  respondent.

  What could be the problem? The host and vCenter are in the same network, net, they have the same gateway by default and same DNS server and they can ping each other same sub.

  Have you already tried to restart the management on the ESXi host agents and tried to add?

  The problem is resolved.

  We did two things...

  1. Deleted Active Directory identity Sources under configuration of Single Sign-on.
  2. Reset the configuration of SSO incorporated.

  After that, we can enter for device via SSH.

  Not sure what is relationship but it has helped me and thought to post our solution.

• Unable to add previous hosts to vCenter device

  Greetings.  We are migrating our guests to new hardware.  We had three hosts for running ESXi 5.5.0 - 1331820 with the vCenter device on one of them.  Everything worked well.  In the process of moving virtual machines around, vCenter device has been deleted (intentionally).  We recreated the device of the OVA 5.5.0.5201 vCenter and ran through the Installation Wizard as previously.

  Now, when you add one of the existing hosts to vCenter, it finds the host and displays information.  When the user clicks on finish, it works quickly up to 80% and the host appears, and then disconnects.  The log shows: add host independent, added host, unable to connect host computer in the data center; connection error host, removed in the data center.

  The error showing is: cannot communicate with the specified host (x.x.x.x). The host may not be available on the network, may have a network configuration problem, or that the management on this host services may not respond.

  
  

  Now the stupid thing is that we can not even add the host on which the vCenter unit is on.  In addition, all hosts and vCenter unit are on the same network of management.  There is no firewall doesn't block all ports.  I read through a lot of the display of the Knowledge Base, and most is in regards to incorrect IP addresses or ports blocked or similar.  I checked through everything and could not find anything wrong.

  
  

  Last thing is that we amazed the ESXi host that had the vCenter device on it and re-installed 5.5.0 - 1623387 ESXi (version a little more recent than before) and reinstalled the that vCenter device exactly as before.  Now we can add that the host but still cannot add other hosts.  So it appears the issue is something with the hosts and not the device vCenter. 

  
  

  Anyone have any ideas?
  

  I run in to the same kind of problems with other factors.

  FWIW, have you tried the following in this order? 1 stop the vpxa on host, 2 service. Stop the service vmware-vpxd on the vcenter server, 3. Start the vmware-vpxd on the vcenter server, 4 service. Start the serivce vpxa on the host. Then try to add.

  Hello

  Resolution

  Cause

  This problem can occur if an ESX host's IP address is changed while being managed by vCenter Server.

  Check the cause

  To check the cause of the problem:

  1. Log in as root to the ESX host using a SSH client.
  1. In the file etc/opt/vmware/vpxa/vpxa.cfg, find the IP address of the host. The entry looks like:

     
     10.21.48.121
     

     Note: for more information about editing the files, see installation in VMware ESX configuration files (1017022).

  Troubleshooting

  If the IP address is incorrect, perform the following steps in order. If the operation does not resolve the problem, continue to the next step. Don't skip a step.

  1. Disconnect and then reconnect the host:
  1. Right click on the ESX host in vCenter Server and click Disconnect.
  1. Reconnect the ESX host in vCenter Server.
  1. Restart the VirtualCenter agent on the ESX host:
  1. Stop the service of vpxa with the command:

     # service vmware-vpxa stop

  1. Open the /etc/opt/vmware/vpxa/vpxa.cfg file in a text editor and correct the IP address of the ESX host.
  1. Start the service of vpxa with the command:

     # service vmware-vpxa start

     Note: for VMware ESXi, you may have to restart all the management agents. For more information, see restart the agents on an ESX or ESXi Server (1003490) management .

  1. Rebuild the VirtualCenter agent on the ESX host configuration file:

     Attention: this step removes all the Statistics counters historical host and the virtual machine. If VMware ESX host is running in virtual machines that starts in a permitted CVS environment, you maybe won't be able to add the host without stopping the virtual machines first.

  1. Right click on the ESX host in vCenter Server and click Disconnect.
  1. Remove the ESX host disconnected from vCenter Server.
  1. Backup the file vpxa.cfg with the command:

     # mv /etc/opt/vmware/vpxa/vpxa.cfg /etc/opt/vmware/vpxa/vpxa.oldcfg

  1. Add the ESX host disconnected to the server vCenter inventory.
  1. Run the following command to view the contents of /etc/opt/vmware/vpxa/vpxa.cfg and confirm that the host IP address is correct:

     # cat /etc/opt/vmware/vpxa/vpxa.cfg

  This KB will show you the steps to re-create the Service Console, but you'll need to console or ILO access to the ESX host.

  Hi JLAPRADE,

  I read a similar case, it seems that the problem could be solved either:

  1) that allows SSLv2Hello to vCenter, or

  (2) upgrade to the latest Foglight/Agent managers to the latest version.

  Regarding the #1 option:

  Client configuration file updated the vpxd.cfg in vCenter. It's the line that needs to be changed:

  TLSv1

  To add the SSLv2Hello Protocol, the client he added after a comma:

  TLSv1, SSLv2Hello

  This solves the problem for this client, but you can check with VMware.

  If the problem persists after trying these solutions or if you have problems, their implementation, please open a request of Service (SR) with the support and mention this thread.

• Unable to connect to the MKS: the certificate of the remote host has these problems:

  Hello

  We have a host of ESXi 4 cluster running any vSphere 4.1.  Recently, I started to upgrade to update 2 and all the additional fixes.  After the upgrade of the vCentre server to the latest version (or maybe before I can't noticed) an of are hosts began to show the following error whenever I tried to connect to the console of any guest on this host.

  Unable to connect to the MKS: the certificate of the remote host has these problems:

  It lists any problems at all and no error display in the event log that it simply does not work.  I had a prod around the internet and found nothing.  I then rebuilt the host to exclude and the problem remains.

  Thanks in advance

  If you can connect to the Console remotely using VMware Infrastructure (VI) Client connected directly to the host, take a look at vmware KB to connect to a remote virtual machine fails with the error: the certificate of the remote host has these problems

  but more generally - remove host to vCenter inventory and then add the host to the back, take a look at opening in the console of the virtual machine after a new installation of ESXi or ESX fails with the error: the host certificate chain is not complete and could not connect to the MKS: the certificate of the remote host has these problems

  If I connect directly to the host ESX 4 it works fine.

  Is that what someone has any ideas, how to solve this problem? I have already tried:

  -Added the new vCenter address and IP to the/etc/hosts

  -restart the ESX servers

  -Re-installed VMware tools to the new vCenter

  None of the above has helped, and I start to desperate... Anyone have an idea?

  If you use vcenter to manage your servers from another computer. You should try to disable the windows firewall on the vcenter computer that manages the esx server. He worked for another problem in the past. Windows firewall started blocking applications of mks someday and we don't know why. Allowing exceptions in windows firewall did not work if the firewall has been turned off completely and then it worked.

• Unable to connect to guest host AD

  I have a Windows 2008 R2 server that is running VMWare Workstation 11. One of the virtual machines is a Windows 2012 R2 domain controller. I can connect to other virtual machines to the domain without any problem. However, I am unable to connect to the host to the domain.

  When I try to connect, I get the following error.

  A domain controller Active Directory (AD DC) for the domain 'corp.mydomain.com' could not be contacted. Ensure that the domain name is typed correctly.

  I enclose the error details. For some reason I couldn't copy and paste in this editor.

  You need to host somehow aware of the "corp.mydomain.com" field in order to be able to join the domain. What can work is to add the IP address of the domain controller (assuming that the DC acts as a DNS server) as an extra entry to the list of DNS servers from the host (such as the first condition in the list).

  How you have configured other systems that joined you to the domain?
