How can i search for vmx files on all datastores in vsphere 5.5. I accidently removed a VM from inventory and have searched through all the datastores so I can add back into the inventory, but cannot find any matching vmx files. The server name may have been renamed after it was created so the vmx file may be under a different name. Is there a way for my to search for vmx files on all the datastores. I will try to add them in one at a time and see if I can get the server I want.

Thanks in advance for your time and assistance.

Great day experts,
I hope all is doing well. I was wondering does anyone know of any virtualization labs books or software that would give you a step by step (or close to it) that I can purchase? As an example, I have purchased "Lab Manual - Enterprise Network Solution Volume II: Setup An Enterprise Network From Scratch - Step By Step Guide For Dummy".
https://www.amazon.com/Lab-Manual-Enterprise-Network-Solution/dp/1519624182/ref=pd_ybh_a_1?_encoding=UTF8&psc=1&refRID=1VWJV5XWAECPDPD1N9KA

We're determining the specifications for two Switches to use between Windows DataCenter hosts of HyperV virtual servers and their SAN.  Is there any reason to get switches with SFP ports, given that the length of cable will only be about 10 feet and that cat 6's capacity is 10 GB (the same as SFP)?  I'm thinking that a 10 GB managed switch with only RJ45 ports would be much less expensive than one that has SFP ports.  We want to use port channel to pair ports of the separate switches together for performance and redundancy, and we want a switch with at least 16 ports.  What is the least expensive switch you recommend?

I am trying to do a Wireshark session within an Azure VM to monitor the network traffic to and from a specific network adapter within the VM,  But when I start Wireshark,  there is no interface at all.   What do I need to ask IT to configure the VM so I can use Wireshark to monitor the network traffic.

Dear Wizards, I setup the ubuntu 16.04 server in vSphere 6.5 with 250 GB hard disk, but days later I increased it to 500 GB, but seems like the VM still had only 250 GB.

How can I claim it back correctly? Many thanks!

I'm trying to convert a vm workstation VM to a proxmox vm.  I have found several guides and I get the general idea, but its still not quite working.  

I took my vmdk and used sftp to move it to proxmox.  

I used
qemu-img convert -f raw a.vmdk a.raw

Then I copied it over using this...
dd if=a.raw of=/dev/mapper/pve-vm--107--disk--1 bs=1M

The issue I have is where to copy the file over too.  The mapper directory doesn't appear to be the right spot.  
I also tried /dev/pve/  

I have two storage ID's  local, and local-lvm   Local has 100 gb of space and local-lvm has 400 gb of space.  I believe I need to copy my raw file over to the loval-lvm, but I am not sure.  

So two questions.
1.  Is this the right procedure to get this acomplished
2.  Where and how do I copy the raw file

I had exchange 2013 installed on a virtual machine on my test Network, and it was working and I was able to send email to clients on my network. I tried to update exchange with cumulative update 20. I installed the prerequisite and after the update started, it crashed on Step 2. I reinstalled the virtual machine so I know it’s clean.
I have backed up the domain controller and the virtual machine I will install exchange server onto.   I followed the instructions from different sites, and I think I have completely removed the previous exchange installation from the domain controller.  Is there a powershell command that can help me confirm that I have completely removed all of the previous exchange installation from the domain controller.? I want to make sure that exchange will install correctly. Any assistance will be appreciated.
Thank you.

Hi

On my Azure VM (Windows 2016) two users can connect at once.

Will Windows Server 2016 Remote Desktop Services user licenses enable more users to connect?
If so, how would I assign this license to my Azure VM?

is this the right approach or should I use the following https://www.microsoft.com/en-us/licensing/product-licensing/client-access-license.aspx#

|					To get VM inventory.

DESCRIPTION:
					This script will connect to vSphere client and get the VMs from connected VC. 
					It will gather all the VM information which needs for every Admin to have as a VM inventory to check quickly or refer in future if something goes wrong.
					Script may takes time to fetch the information as it is gathering deep information of the VM to so you can schedule the script to fetch the information.

					VM inventory output will be store in CSV format so

I'm on esxi 5.5, vSphere 6.5. Something happened where a VM got stuck removing snapshot after a Veeam backup and been running for over 72 hours. We saw no file size changes on files in the VM folder on the host so we restarted management agent on the host.
After the host rebooted, this VM became invalid/inaccessible (it alternates between those two states continuously).
I removed it from Inventory and am not sure how to add it back. When I browse to the datastore and try to right-click the vmx file, the only options I see are Download, delete, copy, move, rename...

Set up a new version 11 vm. Had no mouse so had to use keyboard to install win 10 using an iso created from Microsoft. Installed VM tools using keyboard only as well. Rebooted and screen has been black. I enabled and disabled 3D graphics. Black screen either way. I set a 10 second delayed boot but hitting f8 does not offer me safe mode. Don't have vsphere client, only web client.

Any ideas to get a screen view appreciated.

We recently upgraded our SCCM clients (Configuration Manager) to 5.00.8634.1814.

We did this after upgrading the site to 1802.

After the upgrade all of the icons in Software Center are wacked out.  Prior to the upgrade, something was taking different sized icons and make them automatically appear the same.

In the new version, this functionality works in the List View option - all icons appear the same size regardless of their size.  In Tile View, which everyone uses, this is not the case.  The icons are not being adjusted for the view.

Has anyone else noted this issue?  Is there a setting somewhere I can click to resize?

I hope so.  So far it's that or I have to resize them all manually.

Hi there,

I copied the OS drive from the Azure environment as I want to work on a copy of the VM locally instead of in the cloud.  When I turn on the VM, it fails because it is trying to attach a data disk that I didn't download.  The data disk is 1TB so I don't want to download it just to attach it and not use it.  How can I fix this copied VM so that it only tries to boot and not look for this second drive?  I believe I can remove it by putting int he root password so that I can do some maintenance, but with Azure VMs, the root password isn't set and I don't want to change it just in case something happens on the live VM.   Is there another way around it?

I'm getting these errors:

fsck.ext4: Unable to resolve 'UUID=451a8a0d-0c99-4b34-8702-361627fda1a2a' [FAILED]
*** An error occurred during the file system check.  
Give root password for maintenance (or type Control-D to continue):

Thanks!!

Windows 2012r2 Hyper-v with Windows 2012r2 Guest VM.
We have migrated our accounting application from a physical server to a virtual server.
The accounting software runs at a comparable speed on the virtual server as it did on the physical server.
However, client workstations running the accounting application from the virtual server are much slower.
Example times to run a customer report
   Run application report directly on the Physical server - 3 seconds
   Run application report on network workstation attached to physical server - 10 seconds

   Run application report directly on virtual server - 3 seconds    
   Run application report on network workstation attached to virtual server - 30 seconds

Disk, CPU, Memory and network utilization are all very low.
Can anyone advise a starting point for troubleshooting?

Many thanks in advance.

Hi Guys, I urgently need your help please.

Our power suddenly went off and when it got back on again, trying to Boot VMWARE ESX HOst and all virtual machines power up except for one.

Failed to create swap file '/vmfs/volumes/59c8f306-27517a60-f80b-24be05e127db/spasvr2/vmx-spasvr2-1760552124-1.vswp' : Not found
Could not start VMX: msg.vmk.status.VMK_NOT_FOUND
The virtual machine could not start. Make sure VMware ESX is installed correctly. You must also have rights to run the software and access all directories the software uses, including directories in which the software is installed, directories containing the virtual disk and configuration files, and directories for temporary files.

Your help is greatly appreciated.

Many thanks.,

Hi Experts,

Over the last few years I've been working for a couple of fairly big companies that allow developers, devops and other teams with in the company to request new virtual machines to meet their needs.

From what I have seen in both cases these companies use custom built in-house solutions, that aren't very good. I'm looking for a solution that has a easy to use web base form for the end user to request the server but has an approval chain and back ends into esxi to automate the requests.

This should work with Windows and Linux deployments.

Does anyone know if there is such a tool already on the market? Also what tools are all you other sysadmins using to help automate this kind of requests?
