Virtualization is the act of creating a virtual (rather than actual) version of something, including (but not limited to) a virtual computer hardware platform, operating system (OS), storage device, or computer network resources. Virtualization is usually the creation of a system that executes separate from the underlying hardware resources, or the creation of an entire desktop for systems located elsewhere, similar to thin clients.

Delivering superior services is key to ensuring customer satisfaction and the consequent long-term relationships that enable MSPs to lock in predictable, recurring revenue. What's the best way to deliver superior service? One word: automation.

A VMware datastore consists of 3 LUNs provide from SAN.

Datastore Size- 600 GB
LUN 1- 300 GB
LUN 2- 100 GB
LUN 3- 200 GB

Now if we unmount and remove the LUN 3 (200 GB) what will happen?

1. Will there be any problem with the VMs that are already running on the datastore?
2. Will the datastore size be automatically reduce to 400 GB?
3. Is there any recommendation to safely unallocated or unmount the LUN?

I have a Hyper - V host that hosts 3 VM Servers.  Two of the servers have multiple checkpoints and a "Now" Checkpoint.  Everything is running well, but disk space is starting to concern me.  I would like to merge the current configuration (Now) into the .VHDX file and remove all of the .AVHDX files.  My understanding is that deleting the checkpoints will do this automatically, and that this can be done without shutting down the VM, but I am not sure in what order that should be done.  Oldest to newest?  Newest to oldest? or by some other method.

I have not been able to find documentation on how to accomplish this.

Is there any standard calculation that will calculate the exact size of the snapshot file? I know that the disks snapshot starts with only a few MB and will grow with the VM's disk writes but I want to know the snapshot size before doing any modifications on VM disk.

For example, for 200 GB VM disk with 4 GB RAM what will be the root snapshot size?

I'm trying to install the evaluation version of MS System Center 2012 Virtual Machine Manager and get the following error at the end of the installation (see screen shot).

I did download install winrm 5.1 separately after looking at KB2742275 however that didn't help.  One requirement  MS has is being joined to a domain.  Is there any way to install this without a domain controller present?

Thanks

I am trying to clone this VM to another host and noticed it has 450GB allocated as "Thick Provisioned Lazy Zeroed"
On the OS level though I see only 188GB of this is actually used.
 I would like to reduce the disk size to say 300GB and then clone it but am not sure how to do this.
I think I need to use vMotion somehow but first wouldn't I need to make sure the data in the OS level is not located at the end of the disk?

Im looking to convert one of my physical servers (server 2003 SPK2) to a VM to host on my hyper-V server (Server 2012 R2)

Is there a server backup software that can image the entire disk (1 physical disk 2 partitions) then restore the image to the Hyper-v server?

We use VMware and VSphere client Version 5.5.0.
I have copied the .ova file to one of the data store.

Please provide me tutorials and how to install this  as a Virtual appliance.
Any help would will be great.

Thanks in advanve.

Over the weekend I migrated a physical Windows 2008 to a virtual Windows 2012r2 server.   Due to the large size of the SAN volumes instead of copying the files to a new volume I connected them directly to the new VM  using RDM Disks in VMWare 5.5.

Afterwards I did some random access checks to make sure permissions looked ok.   I was able to access everything I tried which I should have had access to and I was not able to access folders to which I do not have access.  

I then exported the ACL's for each network share and compared them to a export I made before the migration.   I realized there were some missing folders on the new export.   When I connected to the share with my admin account I saw the folder and when I selected it I was notified that I did not have permission to view the folder and it allowed me to grant my self access.   When I look at the permissions they all look correct.   The local administrators group has full access to the folder and when I check the Administrators group our network Admin security group is included as a member.

I removed my explicit permissions to the folder and I was unable to access the folder again.  I added myself again and removed the administrators group from the folder then added it back with full permissions.    I then removed the explicit permissions for my account and tried to access it again without success.  

This is only effecting a few folders so far but I am not sure how to resolve the issue.   I would …

Hello,

I have a Windows image that I want to P2V to do some testing.

I created a VM and the controller defaulted to LSI Logic SAS.

After restoring the image to the VM using Macrium Reflect, I am being prompted for a driver for LSI Adapter, SAS 3000. For which I cannot locate a driver.

I have tried changing the controller type in the VM, but when I do that after a restart none of the volumes are accessible (even to the Macrium Recovery Environment).

So I'm not sure what the resolution is, appreciate some advice.

Thanks

I have a PowerEdge 2950 running Red Hat 6 - 64 that hosts a D3 Tigerlogic Multivalue Database. Been trying to P2V to create a VM for testing config changes. I've read dozens of online responses about the "No Operating System" error on the VM, but Linux is foreign to me and this server has a very complex history. Appears to have HARDWARE and SOFTWARE RAID and several mount points and Samba shares. I've tried the Red Hat DVD rescue fixes, but no go. Just don't understand what the bios is looking for on which partition to get it to boot. I believe all the partitions exist and are complete. Would really like an exact VM replica of the server. Going to try clonezilla booted off DVD next.

I am about to buy a new laptop with SSD, i7 processor, 8 GB RAM, Windows 10 Pro and configurations that should make it considerable faster than my current 5 years old laptop. Then I plan to just transfer my current Windows 7 Home system (with all program installations) from this old laptop to my new laptop to save time and effort and get going immediately.

But will I just transfer this slowness of the old system to the new system?

I found these alternatives:

http://lifehacker.com/5714966/five-best-virtual-machine-applications

Which of them should I use if I am willing to pay and speed and performance is important? Isn't the already integrated Hyper-V a virtual machine application also, so I don't really need any external virtual machine application?

I will buy a Windows 10 Home laptop with a 1 TB SSD, which I will begin with upgrading the OS to Windows 10 Pro.

But then I am unsure about how to partition the 1 TB SSD. I will use Hyper-V in the Pro version to run VMs (different Linux distributions I want to test, perhaps 10 of them). What would the best setup be for the partitions? On my current laptop (which has a 470 HDD), I have the programs installed on C: (195 GB) and data files on D: (270 GB). It has worked well. I have 45 GB free space on C:, and 67 GB free on D:

But now for this new computer I need a partition also for running VMs (if I should have a separate partition for that).

Besides running different Linux distributions  as VMs, I will also transfer my current laptop's contents to the new computer as a virtual machine by doing a clone of it.

Can I keep these different VMs on a flash drive like this (so I don't take up valuable space on the SSD)?:

SanDisk Ultra Fit 32 GB USB 3.0 Flash Drive

And then I use flash drives for the backup of the whole system also? But I need 1 clone (flash drive with VM) for each system, right? But how do I start each OS? Just insert the flash drive, or do I always have to start from the Windows 10 Pro, and switch to a VM from there?

What of what I have described above should be changed? And is it a good idea to only install Windows 10 Pro "permanently", and keep all the rest of the different OSs as VMs (what are the pros and cons between keeping an OS as …

Hello everyone,

I am in a tricky situation with a VM hosting on a stand-alone ESXi host (vSphere v6.0). Long story short, the Datastore1 was getting filled up every time I created a new snapshot so I changed the VMX file to point the snapshots to Datastore2. However, snapshot1 on datastore1 got messed up and I could not delete it. So I created another snapshot say snapshot2 which got created on Datastore2. Now I had 2 un-delete-able snapshots. I could not backup/migrate the VM using VEEAM neither I was able to consolidate the VM. I accidently deleted a couple of snapshot related files which made the situation worse and the machine stopped booting.

Now finally I have changed the VMX file and have pointed the scsi0:0 and scsi:1 back to the original VMDK files (as opposed to the snapshot’ed one). The VM now boots :)

scsi0:0.deviceType = "scsi-hardDisk"
scsi0:0.fileName = "vCSA-2012.vmdk"

scsi0:1.deviceType = "scsi-hardDisk"
scsi0:1.fileName = "vCSA-2012_1.vmdk"

However I have 2 snapshots in the snapshot manager which I cannot delete (error message in the screenshot). The VM consolidation also fails with error, "An error occurred while consolidating disks: msg.snapshot.error-DUPLICATEDISK."

I do not need the snapshots at all because my VM is back in its original form and no data has been lost. At the moment I cannot backup the VM because all snapshot related functions fail because of the mucked up snapshot hierarchy.

I was in the process of converting all 3 domain controllers from 2012 to 2102 R2. All servers are VM. All servers were imaged first. Likewise I have console access if necessary. I had 2 servers built and sized with temporary addresses. I have them both fully patched and ready at the workgroup level. I had only two servers,but had to go to 3. (Long story). I had a server #3 built under 2012 R2, patched and protected. Took it to domain member and subsequent domain controller. I moved the FSMO from #1 to the new #3 as well as copying the database and exporting the CA functions. FInally I updated the GP to relocate the NTP from #1 to #3. I had some problems with SYSVOL and NETLOGON, but managed to copy and configure share permissions and all three domain are replicating. I Meanwhile I use the GUI to demote the #2 (2012 legacy) domain to member server which went cleanly. No forcing necessary.  YEY Bumped it down to workgroup and shut it down.  Brought the #2 new server to domain member and subsequent domain controller and again some SYSVOL and NETLOGON issues. Fixed the same way. So now I have two  2012 R2 domain controllers and one 2012 DC.  I changed #1 to DC from GC. dcidag, nltest, netdom, diags all look good. Attempted to demote #1. Did not work. Required forcing. I Went to #3 and attempted to use AD Sites and Services and it would not delete. (Yes. I unchecked the object deletion). I tried ntdsutil, adsiedit, ldp, some super duper script I got from technet. Nothing worked. I…

We have a VM with display name in VSphere Client as "VM1234" , but when I browse to datastore , the folder is "CHANGE100" and all the files start with CHANGE100

I would like to rename the folder as well as the files in it to match the name VM1234.

I was wondering if it is safe doing it straight through Vsphere Client when browsing to the datastore.


Thanks

Use Case: Protecting a Hybrid Cloud Infrastructure

Microsoft Azure is rapidly becoming the norm in dynamic IT environments. This document describes the challenges that organizations face when protecting data in a hybrid cloud IT environment and presents a use case to demonstrate how Acronis Backup protects all data.

Need to understand the major differences/improvements between deploying the PE R930 vs the Dell/EMC VXRAIL to include flash storage as a scalable VMware solution in order to support over 30+ vm's. Which one gets more bang for your buck.

Hi all,

I've configured ESXi to use an NTP time server:

Does this imply that all the virtual machines sync their time to that clock? It doesn't appear to be the case at the moment.

Thanks in advance.

Hi, please help:
- Can I use "Windows Svr Std 2012 R2 x64 English 1pk DSP OEI DVD 2CPU/2VM" license for Virtual machine? If so, is there any limitation (core, CPU) we have to follow for this VM?

- Do you know how to calculate required licensing for VM (in Vmware ESXi)

Hello experts,
Everything was going good with old production server, we changed the production server now.
We have two share one is for deployment and another is for capture.
our deployment share is working good.
but when I connect to capture share form VM to capture the image it process the bootstarp setting and it process custom settings and I can see"gathering complete, No Ini found"
I saw somewhere on website copy cs.ini to scripts folder  which I did it.
After that it completes slathering and wont do anything after that.

So.. we could not upgrade the vCenter from 5.5 to 6.5 so we needed to do a new install of vCenter  6.5 and name as well, they both are running simulataneously.

I talked to Citrix and the stated I can just update the hosting  configuration with new name and put new certs in and call it a day before i began the process

That was not the case and when I modified the current connection it would not take credentials and called Citrix and then they stated not possible and needed to create the entire thing over . I've googled and found conflicting reports. i did a test connection and used same credentials and it worked.

Has anyone changed an existing hosting configuration with new vCenter name successfully?

Hello,

I am trying to simulate a replacement of VMware ESX on Hyper V running on server 2016.
In my lab, I have two physical servers with the hyper V role installed, the failover cluster manager role and the Hyper V replica broker role. Storage is presented via iSCSI target on Qnap NAS.

Here are my questions.
How do I configure the DRS function? What allows that function?
I attempted to configure Replication, and I received an error that I could not replicate virtual machine to the same cluster.
Suggestions Please
