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.

Purple Screen using VSphere on IBM Server.

Over the last 6 weeks or so, the server has seemingly locked up 5 different times, to the point a hard power down and restart has to be done.    The server is an IBM server with 3 virtual servers set up on it:

AD - Windows Server 2012 R2
File/RWW Server - Windows Server 2012 R2
Exchange - Windows Server 2012

It is running Vsphere and Vmware ESXi 5.1.0

Normally the screen in the server room is black with white text on it, when the server goes down and locks up that screen changes to purple.   I don't now a ton about vmware, or IBM.  There is a internet cord plugged into the IMM port but I don't know the IP address to check for errors in IMM; it's a server I can't take down often as we have employees spread out through out the country, so no real time to get take it down and try and figure it out.

In Vsphere I can't find anything in the logs, or the event viewers on the individual servers.

Anyone know of anything I can check?

Hi again all,

I am new to the virtualization world, and am learning new things everyday.  Today i came across cloning and how to clone virtual Machine and how to create a template and all.

My simple question (out of curiosity)  is for the people with real life experience, what commands do you usually run in a new cloned machine under the run once configuration option ? And suppose am using a windows, when and where are the commands being run?

Thanks in advance!
we need to do high level risk assessment of a VDI (vmware horizon view). E.g. identify potential risks and then look how the design/management/monitoring mitigates against those. The main risks we could think of were the obvious - availability & acceptable performance etc, but am keen to know what kind of risks you would suggest are assessed with such a technology, and the common mitigating controls you would seek assurances on.
I have upgraded the ESXI from 5.5 to 6.0 I have got PSOD Error. Can I go to the previous version? If Yes what is the procedure..
I had this question after viewing Global.Licenses privilege on the vCenter Server.

I am having this exact same issue however I am using the administrator account that is the superuser.  Any ideas?
Hi Guys,

Firewall->HP Switch Layer 3 -> esxi servers 1,2

I'm a vmware vsphere 6 newbie.
I have 2 physical ESXI servers(ESXI v6) that host 30 virtual servers. vmWare vCenter 6 is set up properly. Desperatly looking for some help/advice on this.

Every physical server has 5 gigabit ethernet connections.

Connected NICs:

Management Network x1 (vmnic0)
LAN x3 ( vmnic 1,vmnic2)  (30x Vms)
ISCSI x2 (vmnic3,vmnic4)

Everything is up and running smoothly on our production Network.

Now I need to connect these physical servers to DMZ since there are some vm's that should run on that part of our network.

How should I do that?
What are you guys doing out there?

How about vLANS? Can it be set up and span multiple subnets so I can keep all servers connected to internal LAN?

Thanks in advance.
How to transfer file to ESXi 5.1 host using FTP? I've enabled "FTP Client" on the ESXi host but unable to communicate to the host via port 21.
Hi all,

Am running a lab setup on a server that has 32GiB of ram and 2x intel xeon @ 2.44Ghz, plus my laptop that am basically using the navigate through the ESXI.
Am currently running the 60days free trailer version on my server of the ESXI 6.5, and i have made 2 VM's on my ESXI host, the first one being a windows server 2016 with the active directory enabled and configured and the second VM is a windows server that is connected to the domain but with Vcenter running.

Each of the servers is running on 16Gig of ram and 8VCpu's.

The main problem am currently facing is that i can't open the Vcenter from my web browser (on my laptop), the only way to open is from the Windwos server that am using for the Vcenter (local host) and i had to install google chrome and adobe flash player to be able to open it from the server, another thing i would like to mention is, Yes there is communication between the server and the my machinethe connection is done. before i choose, but after choosing how to access the Vsphere , the connection is lost or dropped, am not sure why.after i choose vSphere Web Client (Flash)Please help me!
Having problems getting expired SSL replaced for VMware Horizon. I have new cert that i replaced the old one with, restarted services, but still have Horizon view in error state. Not sure what I'm missing.
I have inherited an ESXi environment this is minimally documented. I have been able to document location of the guest servers and the main hosts, but I have one remaining problem: I cannot identify which server is handling SRM. Some of the server are protected by SRM and this is causing me issues, as I need to expand some partitions, but can't because the servers are replicating using SRM. Os there a way to find the SRM on the network, either by looking at the host configuration or guest configuration?

vpHow Vplex functions

I have the Snapshot above regarding Vplex.
I would like to know how redundancy works here. Does the VM get replicated  between Storage A and Storage B ?
for instance, if we have VMxyz in storage A and in ESX-01 will this VM be replicated to Storage B and accessed by ESX-03 in case the Datacenter A goes down.

if so then the Vlan on which VMxyz  reside in ESX-01 should exist in ESX-03

Thank you

I have a failed disk in my vSAN cluster. I would like to know the correct procedure in replacing this disk.
I had this question after viewing VM - Virtual machine disks consolidation needed.

Hey everyone (ok mostly Andrew, haha).  I've recently come onboard at my current company as their IT Manager and have never once seen Disk Consolidation is needed in my 12+ years as an IT Professional...until now.  

Due to some very poor decisions by the previous IT Manager, we have a VM that has been locking up during Veeam 12-hour backups as the utility attempts to delete the snapshot it created for the backup.  I've been on the phone with VMware a total of 7-8 hours trying to figure out the issue and they finally isolated it to a couple of rogue snapshot vmdk files that were never removed (dating back to October of last year).  

Below are the details, with some modifications to file names and such to protect our identity.  :)
VMware thinks the main issue is the "713.4G Oct 18 20:44 ProblemVM-000001-sesparse.vmdk" on the first datastore listed below.  They said it appears someone manually diverted the delta file so it could not be written to the base disk.

Good afternoon,

I have a client that wants to change the access password of his Vcenter Server and the contignecia, in both vcenter he has SRM configured, and to authenticate in the SRM he uses the user administrator@vsphere.local, along with his password.

When changing the access password to the Vcenter, would it also change automatically in the SRM?
What would be a good terminology be for your host servers and storage area network? 'Infrastructure' seems quite vague and presumably could include other network equiptment. We want assurances on the documentation of this key area of the network but was after a term that could be used to describe the hosts and storage - any inspiration most welcome.

:) Thank you
Good afternoon,

The present has been fired five times during this month, it indicates as if the monitoring tool does not detect server counts for 10 minutes and it generates a false alarm only on this equipment.

This is a virtual server with Windows Server 2012 R2 Standard, I am doing research at the level of the operating system to validate if I find any news or event that is causing the server to be alarmed.

This is alarm:

Metric "number of times there were no matching counters from server during last 10 minutes changed status from good to warning"

We use the HP Site Scope tool for the discovery and monitoring of servers.

Someone has presented experience with this alarm.

I Need help for cabling. I do not know whichcables connect  to trunk

Where can I download vsphere web client 6.5 ? I have download the  "VMware vSphere Hypervisor (ESXi) 6.5 U1" but I can't find it on client on this ISO ?


We are currently thinking about updating our virtual infrastructure, we have the following products.

-Vcenter Server 5.5 - Quantity five vcenter.
-ESXi 5.5 - Quantity 32 hosts
-Vsphere Data Protection 6.1.2 - Quantity 6
-Site Recovery Manager 5.8 - Quantity 4

The order that we should follow for the update is the following:

1-Vcenter Server

Regarding the issue of licenses, I understand that you must have new licenses to update the platform, in each product? Or with the licenses that I currently have, can I update?

If you need new licenses, would you have to obtain 32 licenses for the ESXi, 5 licenses for the vcenters, 6 licenses for the VDP and 4 licenses for the SRM? For a total of 47 new licenses.

Attentive to your answers.
Hello all,

I have an ESXI host with a RAID10 backed local datastore.  On it reside a few VMs.  Some are off, some are on, however there are about 4 that have a status as Unknown (inaccessible).  I inherited this server from a previous IT guy without any documentation, context or history.  I noticed on one of our Synology NAS, there are two iSCSI LUNs, the smaller of the two is in fact connected to one of our other hosts and has nothing of consequence on it.  The larger LUN is not mapped to any of our hosts but has a bunch of Synology Snapshots on it.

LoL, I am wondering, what you think the odds are that those unknown VMs were once running on that disconnected larger iSCSI target?  Is there a way of getting any kind of information as to what those VMs were or at least where their data stores used to reside?

Related can I just right click and remove these unknown VMs, are there any ramifications of doing so?  I am thinking no, but the only reason I have not, is the previous guy left them like this.

I have Vmware ESXi that I recently upgraded to 6.5 build 7388607 and on a lot of my hosts I've been getting this error:

503 Service Unavailable (Failed to connect to endpoint: [N7Vmacore4Http16LocalServiceSpecE:0x0465c900] _serverNamespace = / action = Allow _port = 8309)

A lot of what I am finding is this error occurring on vC\enter.  I do have vCenter however it has been running fine.  When this error occurs, of course vCenter can't see the host but that's not the issue.  What's causing the error in the first place?
Guest VM cannot connect to my Host machine's Wifi adapter. Using VM Workstation version 14. Using bridged networking, but in the VM, it shows the NIC as a physical NIC rather than Wifi. My host machine is using a Wifi NIC . The VM NIC shows it as no connection. How do I pass network connectivity to the guest VM if my host machine is usning a Wifi adapter?  Both machines are Windows 10 Home edition.
We have 3 ESXi Hosts with local storage and all of our Virtual Machine information is located on the ESXi Host local Disk Drives (Raid-10).  We just purchased a new SAN and the vendor/re-seller is scheduled to install the new SAN and connect it to our existing VmWare Envirnment and IT infrastructure.

Keep in mind that we have an existing Virtual:

- DataCenter
- Cluster
- VCenter Server Appliance (VCSA)

The VCSA is located on 1 of the ESXi host's local DataStores.  My questions are:

1.  Once the SAN is setup, how can I get the VMware cluster to recognize the new shared storage DataStores?

2.  Will Storage vMotion be available automatically when the SAN is connected to the VMware cluster?

3.  How may I migrate the VCSA from the local storage to the shared storage?
