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.

VCenter Physical /Virtual

in Our Environment ,I am logging to Vcenter named "BM-Vcenter", however after I logged in I see there is another Vcenter Virtual machine with the same name "BM-Vcenter". I am a bit confused how this can be.

Any clarification will be very much appreciated.

Thank you

To create vMotion between two VMware server under shared storage, do I need to put these two servers in the same clusters ?

For the shared storage, does it mean that both servers access the same iTarget (ie. same IP and port number ) ? How can same iSCSI target been shared between two servers ? Will it cause data inconsistency when two servers need to write data at the same time ?

Thx

I need to update 2  existing VMWare Hypervisors to 6.0/6.7 from 5.5.
I was planning to update Host1, power down and relocate my 4 Virtual Machines to Host1 and then update Host2 to minimise my business downtime.

Has anyone done an update similar and discovered problems along the way?

Hi,

I'm trying to use Vmware Vcenter Converter Standalone to convert a Vmware workstation machine and put it onto our Esxi server.

However, at the stage where I am being asked to enter the Destination System details and when I do and select 'Next', I get a A general system error occurred: SSL Exception: error: 14077102:SSL routines:SSL23_Get_Server_Hello:unsupported protocol.

I have tried manipulating the .xml files on my own machine by going to converter-worker.xml and converter-agent.xml by changing tag <sslOptions> from 123422720 to 56313856 and then restart services.

I have also gone into converter-worker.xml file and changed the 'UseSSL' to 'false' and restarted services. Still nothing working.

Attached is a screenshot.

Any ideas?

Thanks for helping

Hi guys

I did a P2V of a Windows 7 64-bit machine with the Vmware converter. However, I would like to now run this on our Esxi servers.

I am running Vmware 5.5.  I have tried adding the .vmx file to the inventory and that showed it as 'invalid'. So I created a new VM and removed the original disk and added a new existing disk and proceeded for it to see the location of the .VMDK file. When I powered it up, I got an error about the scsi drive I believe. I deleted the VM like an idiot and so I forgot the actual error.

Is there a way you would recommend for this to work?

Thanks for helping

We have a vCenter Server appliance (6.0.0.20000 Build 3634791).  All was running fine until we shut down the appliance (cleanly) for a planned power outage.  Since it came back up, it is no longer possible to access it either with the vCenter Web Client or the vSphere Client.  There have been no other changes made.

The vSphere Client reports:
---------------------------
Could Not Connect
---------------------------
vSphere Client could not connect to "vcenter".

An unknown connection error occurred. (The server could not interpret the client's request. (The remote server returned an error: (503) Server Unavailable.))

The Web Client shows:

503 Service Unavailable (Failed to connect to endpoint: [N7Vmacore4Http20NamedPipeServiceSpecE:0x7f085805ee10] _serverNamespace = / _isRedirect = false _pipeName =/var/run/vmware/vpxd-webserver-pipe)

We have confirmed that the vSphere Client service will not start:

Hi experts,

I connect to VPN to a clients environment via Cisco AnyConnect Secure Mobility Client.  Once connected I then remote desktop into the machine at the client and I can work etc.

Whenever I do this I lose all internet access from the laptop I connect through at my home.  So I can't have an email client running locally as it will not connect to email server.  I can't minimize the remote desktop and browse internet with a local browser.  It's like it completely takes over my internet for some reason.

So I created a new VM via VMWare and thought I would just use the VM to vpn into the client as the VM should share the internet connection.   To my surprise, even when I do that, the internet will not work on my local machine.  The VM completely takes over my entire internet once I connect to Cisco AnyConnect.

I figure this is probably security related but is there anywhere or any setting I can do so it shares the connection?

Or in VMWare something where it won't allow it to take over entire connection?

Thanks for any inisight.

We know this is a complex topic.  We are looking for some insight and possible links that can helps in cloning a VM of vmware which is a the main domain controller server without damaging configuration of said domain.  We understand to-that if we disconnect the DC in order to clone it, the DC will lose  vital configuration required for the domain (reason we haven't proceeded until all info at hand for proper process).

Cloud Class® Course: C++ 11 Fundamentals

This course will introduce you to C++ 11 and teach you about syntax fundamentals.

I have a windows 2008 R2 server guest sat on VM Ware server which has being showing removing snapshot session for over 24hrs now. The guest itself is not accessible currently so via the console in vshpere, when try to connect I get the error Unable to connect to the MKS: Error connecting to /bin/vmx process.

I have other guests sat two guest sat on the same host but they are on a different datastore. The server which is hung is on its own storage and there is over 800Gb free.

It looks like the Remove Snapshot process has hung?

What is the best course of action to bring this back online.

Thanks

There is approx 64 sql machines on test and production environment, from sql 2003 , 2005, 2008 and 2012

Looking to put in a plan where all these machines can go into 2 ESXi hosts using cpu and memory as main guidelines

I got the SQL VMware from Andrew Hancock,

Just looking for the best way to work this out, proc type is CPU E5-2690 v4 @ 2.60GHz and they are Lenovo physical machines

Altogether the machines come to around 160 cores (I just added them up) looking for the best way to do this in a few steps if possible

Ideally just the steps i would need to go through to implement this at a high level, is it feasible to have approx 33 SQL machines on each host?

What are the factors I would need to take into account? Realise this is an open question appreciate any help for this

I have various models of Xerox MFP units that will periodically have a failure to deliver messages to my Microsoft Exchange 2016 server. I believe the receive connector is not the issue, because the issue comes and goes. The message from the copier delivery failure report is:

One or more messages were not sent. Insufficient resources on the sending mail server (SMTP). Contact your system Administrator.

Other mail continues to flow in and out of the server. I do have a DAG setup with a second server. Both are virtualized in VMWare ESXi.
[PS] C:\Windows\system32>Get-ExchangeServer | Select Name, AdminDisplayVersion

My mail servers are running:
Name      AdminDisplayVersion
----      -------------------
HDH-MAIL1 Version 15.1 (Build 1034.26)
HDH-MAIL2 Version 15.1 (Build 1034.26)


My thinking is it is some sort of performance issue but I am really unable to correlate it to anything. I also have not been able to determine which logs I should be looking at to help troubleshoot. Any help is appreciated...

Looking to reorganise SQL servers, there a mix of 2003 2008 and 2012 servers all virtual machines

Approx 65 in total there is a datacentre migration from 5.5 to 6.5 so its half and half at present

Is there guidelines for SQL virtual machines and ESXi host configuration , any other guidelines I would need to be aware for organising SQL machines in vCenter

Cant consolidate snapshots due to insufficient Disk Space!

Vcenter 5.5

I ran a comvault backup on a 11TB vmdk and did not realize i did not have enough space and comvault forced the snapshot anyway and now my 11TB Datastore dedicated just for that vmdk doubled in provisioned size to 22TB!  
Insufficient Disk Space
I have tried the steps in Hancock's link here https://www.experts-exchange.com/questions/28704560/Insufficient-disk-space-while-tring-to-consolidate-disks.html

With no luck :(  

The VM is powered off and i tried migrating it to a 12TB lun and it took almost 24 hours and got to 93% and then the task in vcenter just disappeard! no error or message!

Im guessing the 12TB lun was not big enough, but then why would Vcenter allow me to even start the Storage migration task?

anyway, I really need help on this one i am trying to avoid having to increase the 12TB lun to 23TB just to migrate the vmdk

Also what ever will be the fastest solution would be ideal.  I am worried i might of corrupted the data too :(

please help

Thanks

Any idea how to server the disk size and free space for VMware server (not the VM guests) with PowerCLI ?

There is a need to extend VMWare Disks on two Windows Server 2012 R2 Standard File Servers running DFS Folder Replication. 

Due to VMWare Limitation of a 2 TB limit for Hot Extension of VM Disks,
we have to shutdown the server to extend the disks.

Plan previously followed:

1. Disable Folder Target in Namespace to all folders pointing to File Server that will be shutdown first - leaving the Folder Target Enabled in the Namespace to the other file server in the DFS Replication pair.

2. Shutdown the Server. Update the Disk Capacity in VMWare. Extend the Disk in Diskpart / Disk Management.

3. Enable Folder Target on Server with Extended Disk. Wait 24 hours for Replication to catch up.
 Then Disable Folder Target on the Other Server and repeat step 2 for the other server.

4. Enable Folder Target on 2nd Server (all these steps are in the namespace from Step 1 to 4)

When looking at Sessions and Open Files under Computer Management -> System Tools -> Shared Folders.
See a lot of Open Files in various Modes of No Access, Read and Read-Write.
Under Sessions, some users have Open Files with a session Connected Time and Idle Time ranging from a few hours to 40 days.

My question is after Step 1, 24 hours have passed but am still seeing a lot of new sessions been established to Folder Shares on the Server that needs to be shutdown
(connected and idle time ranging from 3 seconds to 19 seconds).
Where are these sessions for non-IT users coming from?
Any …

Cloud Class® Course: MCSA MCSE Windows Server 2012

This course teaches how to install and configure Windows Server 2012 R2.  It is the first step on your path to becoming a Microsoft Certified Solutions Expert (MCSE).

I have vmare vcenter 6.5 with a datacenter and cluster with two nodes, lets call this site A.  I have vmware esxi 6.5 installed at a remote location on one node, lets call this site B.   Site B does not have vcenter. I have mpls between the sites and no ports are blocked.  

I want to replicate traffic from site A to site B.  Can i create a new datacenter at Site A using vcenter and add the node at site B to this datacenter?    
Could I enable replication from datacenter to datacenter which are both now in my vCenter at Site A?

i have essential plus license for 3 nodes.

I am assigning tags by OS so we can easily identify the version and have completed all except 2012.  The GuestIDs and GuestOS should be the same so i cannot use the same method as i did for others.  I suspect i'd need a WMI search added to this powershell but I'm unsure.  

Is there a way to modify this script to differentiate between 2012 and 2012 R2 in VMware?  I'm running vCenter 6.5 with ESXi 6.0/6.5 with Powershell 5.1.14409.1012 and PowerCLI 10.1.0.8403314.

#Enter the Tag you want to search for or assign 
$tag= "Win 2012"

#Get the virtual machines of a department in your organization.
$vms = Get-VM | Where { ($_.GuestId -eq "windows8Server64Guest") }

#Assign the custom tag to the group of virtual machines.
$vms | New-TagAssignment -Tag $tag

#Get all virtual machines tagged with the tag.
Get-VM -Tag $tag

As I understand it, vSphere "Host Failure" happens when a host cannot communicate over management AND datastore networks, while "Host Isolation" occurs when either management heartbeat goes down or datastore heartbeat goes down for a host, but not both. Is this correct?

If host isolation is due to management network issues, I see no need to shutdown and restart VMs on a new host. However, in case of communication failure of a host to the datastore, restart of VMs is desirable. What HA response is recommended during Host Isolation? I seem to think Disabled is better if management troubles are more likely. Please advise. Thanks.

Hi
We use VMware and our exchange 2007 server while taking a backup it was frozen for some reason and I hard reboot the server. After I rebooted the exchange server on the vSphere, I right clicked the server and logged into the exchange server and the server is up and running now.
The interesting thing is, I am not able to RDP into the server and It was working ok and all of sudden this has happened after the server was rebooted from a frozen state. On the vSphere client if I click the server – Summary – It says VMware tools not running.
IP addresses is blank.
Please suggest how to resolve this.
