VMware is virtual machine software that provides a virtualized set of hardware (a video adapter, a network adapter, and hard disk adapters) to the guest operating system. VMware virtual machines become highly portable between computers, because every host looks nearly identical to the guest. In practice, a system administrator can pause operations on a virtual machine guest, move or copy that guest to another physical computer, and there resume execution exactly at the point of suspension. VMware's enterprise software hypervisors for servers, VMware ESX and VMware ESXi are bare-metal embedded Hypervisors that run directly on server hardware without requiring an additional underlying operating system.

Hello,

I am upgrading my vcenter from 6 to 6.5.  The database is on an external SQL server.  

I am getting the attached error.  ODBC test between the vcenter server and database server is fine.  

I am check out this link http://iamoracleadmin.blogspot.com/2017/03/vc65-db-lock-has-been-detected-on.html but I am not sure now to identify the opened session and kill it.  

I am not sure if I should post this to the vmware team or SQL team so I am posting it on both.

Anyone who knows how to fix it please advise.  

Many thanks.

Add VM to Vsphere Client 6.7 and install OS

I have Small Damn Linux ISO on my PC where I installed VMware Workstation.
I have installed Vcenter on Vmware Workstation and have opened Vsphere Client from within Vcenter, I created new VM, but I want to point the CD  to the ISO image on my PC.
Not sure which option in the screenshot below should I select, because neither of them will allow me to browse to the location of the ISO image.

Vmotion vMKernel port

in a standard switch we can configure vMkernel for vMotion, this,  I believe should  have an IP address assigned to it, let's say 192.168.1.15
Now if in every ESX host in the cluster I need to configure vMkernel port which is recommended, then should all vMkernel ports be in the same  VLAN ?

Thank you

MTU change on vSwitch

If I need to change MTU on vSwitch to 2000 Bytes , then should I have to change it for the same size on Every VM Port group and every VMKernel?
For instance on vSwitch, I have VM Portgroups on VLAN 10,20,30, VMKernel  Management in VLAN 40, MKernel for vMotion in VLAN 50 , VMKernel for Storage in VLAN 60

Thank you

Hi,

I have a central server to which I execute lots of PowerShell commands, executed by (a PowerShell gui) clients remotely. For each user I create a ps session to via a register-pssession then with the name of that user.
That way I also avoid the dual hop (f.e. a script executed has to do a test-path).

That way, this server executes all the load (running sql queries, getting vmware details, sccm details etc) and only a firewall port to that server needs to be opened, also no ps modules needed on the clients.

I reboot the server daily to avoid issues.

I do am concerned about the stability and lozd though. Now there are only few users but there might come many more.

Is there maybe a better approach for this setup?

Please advise.

Vmware Thin/Thick Lazy and Eager

in Vmware Disk types, we have :

Thin: Allocate and zero on first write
Thick Lazy: Allocate in advance and zero on first write
Thick Eager: Allocate and zero in advance

that was what has been explained on the web.

What I do not understand is the term "ZERO"  used by Vmware.
Do they mean delete any previous existing Data  from the Disk ? if So , then I believe that 's obvious and should be automatic, when you assign a new virtual disk to a VM it should be formatted and have all data on it deleted....
Sometimes, you need to allocate existing Disk to a VM, in this case your intent is that the Data should stay on the disk.. and if you want to delete it then you can format the disk..

Any clarifications ?

Thank you

VMware 6.5

I had my vCenter VCSA crash the other night and still can not get it to work.

It was a HA setup and both passive and peer nodes went down.

I shutdown all three Passive peer and witness  started one at a time and found out that on the passive VCSA I lost the primary network adapter.

I found that the network adapter is not set.   I assigned static ip addresses I tried DHCP but the ip address does not stay

 

I logged onto the VCSA and ran this

 

ifconfig

 

/opt/vmware/share/vami/vami_config_net

 

  Main Menu wiil
appear

 

Select option for
network adapter,

 

I set the adapter to the ip address

 

I now cannot bring up vcenter at all.  

 VCSA

I then decided to create a new VCSA appliance and that worked for a while.  I updated the VCSA and after the update I can not access vcenter at all


Any ideas or suggestions?

Need help thanks

Hello
We have three domain controllers installed in Windows Server 2016 (virtual machines in VMware vCenter 6.7). And we need to create a similar test environment.
For that i restored a backup of one domain controller, and tried Seizing FSMO roles (i used these steps lots of times in different version of Windows Server 2003, 2008 r2, and it worked perfectly).
But now, after seizing all FSMO roles, and restarting the test domain controller, AD fails to work correctly.
When i run the command NETDOM QUERY FSMO to check to roles holder, i get error saying:
The specified domain either does not exist or could not be contacted.
I precize that, DNS resolution is working and FSMO roles are seized using NTDSUTIL commands.
I wonder how can i make it work correctly?
Thank you in advance,

Hi,

Hope you will help or at least point me out to the right direction.

I'm using Veeam 9.5 update 4b with 5 Esxi host with Vcenter etc. I have installed Veeam on a dedicated Physical server (Windows 2019). The Disk to Disk part working absolutely fine but the problem is Disk to Cloud. I'm using Azure BLOB storage. Azure repository been crated and configured in Veeam. Also, created the SOBR (Scale Out Backup Repository).  As a testing purpose i have changed the "Restore Points to keep on disk' is set to 3. Also, set the "Move backup files older than 2 days'. Unfortunately even after 3 days the backups aren't uploaded to Azure container.

Any idea what could be the issue here?

Hello,

I am upgrading my vcenter server (Windows VM) from 6.0 to 6.5.  I am stuck in the attached screen.

Do I need to shut some Windows services on my vCenter server to proceed?  

Please advise  

thanks.

We have a serer that currently has 3 pretty decent size drives that are on the same datastore and DBA is reporting performance issues and wanted to start with basics and I'm thinking that we separate the disk to different datastores to see if any change and curious what your opinion on the matter would be?

VMware does not really seem to have a great opinion on it and not 100% this is a straightforward answer but wanted to at least begin the dialogue.

Configuring Vmkernel port for FiberChannel

is it the same as iSCSI ?

We need to purchase a license for SQL Server 2016 Standard edition to be installed on a new VM running on Vmware 6.5.

The pricing model is a little confusing as it is per core, but will be on a esxi vmware host - but i assume it will be looked at for the number of cores i assign it within vSphere.

Please assist in understanding the true cost (server license or server license plus CAL?) of creating a new VM with that version, one SQL instance with multiple databases.

Thanks!

Hi,

A friend has created an image and I am using VMWare player 15 to open it.  The system image is on UBUNTU. I am trying to login to it using the GUI interface and what I got after login is a field like this root@chwoodman01:~#  (see screenshot attached)

There is a command-line I can type to see the Graphic User Interface?

Can you please advise?

Hi, first time using VMWare and having problems getting the network to work as expected. I have a HP Proliant server with 4 NICs, I have 2 of these connected to a Draytek 2830n. The server has been running fine with Windows Server 2016 and Exchange. We now have a need to run VMWare using one on the other NICs connected to port 2 of the Draytek but I can't get the VMware Workstation to ping the draytek or get dhcp from it. I have assigned an IP Address to the Host NIC and also to the Virtual one, I have tried bridge connections in VMWare and also custom specific virtual network. On the draytek i have setup vlans and this is connected to vlan 2.

Help please, maybe best to start from scratch with a guide although I have tried following the guides on VMwares website.

Thanks, Peter.

Hi Experts!

I've been trying to troubleshoot an issue with this setup without success, hopefully you can help me.

With this current setup (diagram attached), I can perform a NAS failover from storage controller SPA to SPB but then I cannot failback from SPB to SPA. During the failback the datastore mounted on ESXi becomes inaccessible, if I failover the NAS again from SPA to SPB the datastore becomes available again automatically.

Here are the scenarios which worked for me, one test at a time:
1) Turning off switch 1, the datastore on ESXi remains mounted, good, turn it back on.
2) Turning off switch 2, the datastore on ESXi remains mounted, good, turn it back on.
3) Failing over the NAS on storage controller SPA to SPB, the datastore on ESXi remains mounted, good.

Here's the scenario I'm having trouble with:
1) Failing back the NAS on storage controller SPB to SPA after a successful failover from the above scenario

I've also noticed that if I leave the NAS server long enough on the SPB I can eventually failback to SPA without issues, but then it reverses path, I cannot go back to SPA. It seems to only failover once, but never failback unless I give it enough time.


Port-channels and vPC are up successfully without inconsistencies.

The switches are Nexus 3k. Storage is EMC Unity.


Any thoughts on what else I can check/test/do? Much appreciated, thank you!

We have discovered a lot of certificates on servers as well as workstations that seem to be self-signed and also seem to be generated by some automated process.  We have confirmed that Group Policy is NOT triggering any of these certificates. I have a project to replace ALL self-signed certificates with ones created from our Internal PKI.

The major number of server certificates are either port 3389 or 443:

The 3389 certificates (around 1500):

1.      These are “all’ self-signed (the Issuer and the Subject are the same) and validity period is 6 months and they are ‘all’ valid (meaning not expired).  

2.      Does windows create these certificates ?  What process triggers the creation of these Remote Desktop Service certificates ?

3.      Where are they stored ?  I can’t find them.  Will they be in the Computer or User store on the server ?

4.      What purpose do they serve ? Can I delete them since they are self-signed ?   We are trying to replace all our self-signed certs with ones generated from our Internal PKI.

 The 443 certificates (around 1200):

1.      The majority of these are also self-signed.

2.      They have expiration dates in 2024, 2036, 2049 etc.  

3.      The issuer has mostly to do with ‘vmware engineering’ or something else that has to do with vmware.   Is the VMWare creating these certificates ?

4.      How do I remediate (delete\re-issue) these ?   I can’t revoke any of them because they are self-signed.  

5.      The expiration date is in the future, but how do I…

Hello,

We have vCenter server 6.0.0,7462484.  This is update 3d.  

Someone told me the latest is u3j.  

However, when I go to this link https://kb.vmware.com/s/article/2143832, I do not see u3j.  I am not sure which one to download.  

I also have another important question.  Is patching our u3d to the latest is going to wipe out the database?  Or it is an in-place install.  Our vcenter database is on another SQL server.

Expert out there, you must have to changed the IP address of Esxi host and vcenter.
I would like to change the IP on the ESXi host and vcenter. I will appreciate it if you could shed light on this.

We have about 40+ MS Windows 2008 servers, most of them are VMs. We are using VMware ESXi. We are thinking of upgrade all these servers to 2016. I heard that we have to upgrade to 2012 before 2016, is this true?  

Can someone share how to upgrade to 2016. Any documentation for this?

Thanks in advance.
