    Is is possible that you have the vCenter foundations license?

    If you bought the vSphere Essentials Kit you will have a vCenter Server Essentials license as part of that: https://blogs.vmware.com/vsphere/2018/10/vcenter-server-licensing-options.html

    i have a valid license for vcenter 7 and the license was key in an accepted.

    the two hosts are also correct licensed with vmware vsphere essentials 6, this host can be load in vcenter, the second host is licensed with vsphere essentials 7, and this host can be registered, then it will be removed with the message "incorrect username or password". Username and password are correct!

    what can i do?

    Hello.
    You can show the entered licenses from the vcenter, of course hiding the key.

    That way we will know what kind of licenses you have and how many you have.

    Hello
    You would have 2 Essentials kits, one version 6 and one version 7 so you would have a vcenter server and 3 hosts (2CPU) for each kit.

    In the image you sent from vcenter Essentials 7 I see the following licenses entered:
    vcenter Essentials 7
    VMware vSphere Essentials 6
    vSphere Essentials 7

    Since the vcenter is Essentials, I am not sure that it can manage 2 different types of tenders (Essentials).

    .
    Is there any reason why I need to have this mixed license burning?.

    I will keep looking, but your case is out of the ordinary

    Yes, there is a reason. My old server ibm x3650m3 is not compatible with vsphere 7 and the server is eol and the disk space is full. I have buy a hp server dl380 gen 9 with more memory and disk space. When the two server are in vcenter, I’ll will migrate all virtual machines on the new server.

    i have change today the tiny installation to a small vcenter installation, with the same issue.

    i am able to add the ibm server with vsphere essentials 6, but not the the hp server with vsphere essentials 7.

    vcenter 7 is installed as virtual machine on the hp server and licensed correctly.

    the error message “incorrect username or password” is not the correct issue, the host will be added and then removed with this message!
    who can help or analyze the problem?

    The topic is old, but I did not see the answer.

    I made a fresh installation of ESXI and VCSA 7 versions, and hit the same problem, I still have to figure problem out the memory.


    And adding a new ESXI host took a long time. I have tried a lot of things described in the community. I was able to add new host only using the ROOT account on ESXI, which was immediately deactivated after a fresh installation according to the security policy(habit).

    I do not understand what permissions an account different than root should have, if administrator rights are granted.

    It is checked on 2 hosts, it works!

    PS. root account may deleted after host added.

    For memory warning on VCSA 7 for tiny environment >> Please try stopping the vmware-pod service and check after 15-20 mins if the warning again triggers.  Worst case is to increase memory by 2 or 4 GB .

    You no need add RAM to VM.

     

    Connect SSH to vCenter Server Appliance, enter bash command "shell".

    List current service RAM set (save before edit):

    View memory usage statistic:

    If value in "CurrentMB" above "AllocatedMB" - may, but not neccesary, need up service set.

    Worked for me to solve problem in default VCSA installation:

    Refresh Health status on vCenter Server Manager page.

    This worked for me too. A Default 7.03 vcsa produced the same error within just a few hours and remained for 7 weeks. I even added 2 GB of vRAM before making the changes (and waiting), and still "low on memory." Within 3 minutes of making the changes above, problem solved. 

    It appears to be an allocation problem, and these commands above reserve/allocate more RAM to these two services.

    Did vmware actually test their vcenter install options before releasing it?

    I did a tiny vcenter install, the next day the vshpere client service had crashed already, with two basic hosts attached into vcenter and nothing else done to it at all, just a basic out of the box install wth two hosts and two vm's for playing with one on each

    Also had the memory running low error as well from the start.

    Wouldnt they make the vcenter work out of the box without requring command line options to change memory requirements of services from a first install??? Feels like its a beta release so far, never had this problem with previous vcenters

    Agreed. I just had the same issue. The Tiny installation seems bugged with the default memory allocation for vsphere-ui and vsphere-vpostgres.

    Same issue on a brand new install of VCSA 7.0.3.00800 despite this KB saying it would be fixed in 7.0.2.

    https://kb.vmware.com/s/article/83824

    At least update the KB.  JFC.

    It's a little waste of resources, but I decided to just install the Small appliance. Besides getting rid of the error, vCenter recovers faster after updates or a full reboot. I used thin disks to help conserve some of the disk space.
