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.

Hi,

I saw in the server room there were a host of VM machines (a physical server which hosts 4 vm machines).

I also saw NAS (Network-Attached Storage) and SAN (Storage Area Network).

Question: Which Storage Area network did the above the host of vm machines use? NAS or SAN? Why?

Moving a vmware 2k8 to hyper v

I have inherited a vmware esxi 6 host that was a free version which has long expired into the limited host. I have taken responsibility for this and want to move to hyper v so it is all properly backed up etc on newer servers. My issue is there is only the vmware host and no vcentre or other way to manage it and I cannot export it off the Host to a hyper V. All other infrastructure is hyper V so getting vcentre makes little economic sense. MS virtual machine converter won't do it as it says it needs vcentre, vmware converter only exports to vmware. So what to do? They aren't completely critical servers they are bdc's and av servers so could be rebuilt but would really like a way that didn't involve that at the moment.

Hi I have to do system architecture diagrams for environment

Its very documentation heavy, have to cover VMware, Active Directory, 2008R2 forest mode and on premise Exchange 2010

Is there any guidelines people would recommend i realise its a general query

For instance are there free tools that provide mapping which i can use with visio

I have seen the free stencils Veeam provide and they look good

I am looking to do high level overview then go a bit deeper and also include support documentation which will be a lot more straightforward

Any pointers appreciated

I am cloning a VM in 6 via a powershell/Powercli script.

VMWare clone doesnt generate a new MAC address on the cloned vm and retains the original MAC,  what command can I use on my cloning script to generate a new MAC for the vNic?

Hi All,

Used disk2vhd to convert an 2003 server. The conversion went well, i choose vhd as an option. Now I'm trying to attache the hard drive to a Hyper-v Server 2016 and getting the error below. I moved the vhd file to suggested location, checked permission but nothing. Have a feeling it has to do with a compatability issue with server 2016 and vhd files. Any help appreciated.

I have 2 identical dell server hosts running esxi 6.5.  I have Vcenter installed on one of the windows server 2016 VMs running on host A.  I have the Vsphere essentials PLUS kit.  I have added my datacenter and my cluster. I turned on HA on the cluster and i can see that it is monitoring the master host and will change over to another host if I pull  the network cables from the master.  But my VMs appear not to be migrating to the other host.  I am running an iscsi NAS  for shared storage and added that as a new datastore to the cluster.  on the NAS i do see some small files created to show powered on host status.

where can i start to troubleshoot why the VMs are not available to the other host?

my venter is dead , how can I remove the host and have it operate by itself

i have no need for vcenter at this point  , how can I get rid of this message if I cannot get into my vcenter to remove the host??

I have a 2012 R2 Standard Virtual Machine that Remote Desktop Services fails with error Your Computer can't connect to the remote computer because your computer or device did not pass the Network Access Protection requirements set by your administrator.  I am using Certify the web SSL Manager for the Certificates. If I open Remote Desktop Gateway Manager > Properties > SSL Certificate and import the Cert i created with Certify everything works no errors  when we connect to remote apps. The problem is when the server is rebooted the Certificate gets removed and i get the error so i have to re import the certificate every time the server is rebooted. I also have the same cert in the bindings of the Default Web Site for Https.

I licensed my below setup so I could run 4 HyperVs on each physical server

If one of my PHYSICAL servers dies can I restore 2 Windows Server 2016 HyperVs backups onto the remaining PHYSICAL server without having licensing issues since I have enough LOCAL storage to support all 4 HyperVs on one PHYSICAL server ?

Setup
 ** 2 PHYSICAL "16 core licensed" Windows Server 2016 servers via OEM licensing, not OpenBusiness/etc
      ** each hosting 2 Windows Server 2016 HyperVs
      ** each using LOCAL storage

Hello all,
Last night Veeam Backup Job has given an error for a virtual machine. When I looked at this virtual machine in the morning, I saw that it was closed because there was no space on the hard disk (retry / ignore screen). however, there was enough free disk space. At the same time, Veeam could not delete the temporary snapshot that it created for this virtual machine.
for this reason the virtual machine needed disk consolidation.
I increased the disk size through the storage and I could open the virtual machine.
then I started the consolidation for the virtual machine with vSphere. but every time I got this error. "an error occurred while consolidating disks: 5 (input / output error)

I shut down the virtual machine and tried again.
I manually deleted the temporary snapshot, my attempt failed.
I tried to manually take the snopshot and it failed.
I manually deleted the SnapShot that I took manually and tried again.

how can I get rid of this situation? I really need help. because in this case the virtual machine is over-consuming hard disk. Today I made a 100GB disk increase in total, but it quickly consumed this space too.
Thank you in advance for your support.

Best Practice for Veeam Backup:

Hi,

we have a Cluster running with 14 nodes.

Each node contains different VM's.

we use Veeam for backup.

Would you use 1 backup job to backup the Cluster of would you create a backup job for each customer on the Cluster. A customer has about 4 to 10 servers in our cluster.

Of how to do this best?

I have recently migrated Windows Server 2008 R2 virtual servers running in a VM environment onto new hardware. i.e. new esxi host servers and new physical datastore. Since then I have been receiving messages on my server saying that Windows is not activated. There does not seem to be any way of activating the operating system now.

Cannot boot ESXi 6.5 host from USB because Fatal error: 33 (Inconsistent data) xorg.v00?

I properly powered down my host but it didn't come back up. I get the error described above. I know its silly i but i didn't have a copy of the running config or a copy of the image of the USB.

I have two stumbling blocks;
  1. when i followed the instructions described in https://goo.gl/UgMCF7 by Andrew Hancock, i got stuck at step 1. The USB couldn't be backed up 'couldn't read media message.' Not be out done by this message, I skipped to step 2 and followed it all the way to checksum.
  2. The checksum is different between the corrupt and the one i recreated from different machine but with the same esxi install file. This is probably because i have updated the host since i last installed it.


  • Do i need to recreate the install from the same machine in order to have the same checksum?
  • What would happen if i replaced the file with a working xorg.v00, with a different checksum?
  • If i did a new fresh install from a different USB, will i be able to recover the Data in my datastore using the same config. I mostly care about the data thats in the datastore.

Any help will be greatly appreciated.

Thanks in advance

I am in the process of setting up our Windows Server 2012R2 VM in Azure for PCI compliant ciphers and protocols. When I disable TLS 1.0 I get an error in my system log:

A fatal error occurred while creating an SSL client credential. The internal error state is 10013.
with an Event ID of 36871

Most of the answers I have seen are for server 2008 and in regards to SMTP. There is nothing that runs SMTP on this server, it's just an IIS box hosting a few web services. RDP works just fine, everything else seems fine, kind of confused as to why disabling TLS 1.0 would do this. When I re-enable it, the errors go away.  

Any Suggestions?

I have a HyperV server with three VM's. Each VM is plugged into separate NIC. The IP addresses for the virtual machines are hard coded 10.140.10.50. .51 and .52

In Network Connections on the HyperV Host I see the three NICs which are named for each VM. Each one is set to obtain an address from DHCP.   I had thought that these would be the same IP as the VM but evidently not.

What is the best practices for IP addresses for these NICS. Should they be the same as the VM, a static IP on the same network or a static IP on a different IP network?

Good morning, a few weeks ago install a Vcenter Server Appliance 6.0 for a client. The installation was a success. But the client must obtain an active license in vmware.

He told me that they made a quote and they indicated these licenses and I wonder if he bought them all or only one:

Vmware Vsphere 6 Essentials Plus Kit for 3.

Basic Support / Suscription vmware vsphere.

Vmware Vcenter Server 6 Standard

Basic Support Suscription vmware vCenter.

He has only two Esxi.

Stay tuned to your comments.

regards

Dear Experts, we tested this concept: https://helpcenter.veeam.com/docs/backup/vsphere/vm_processing.html?ver=95 but did not see the difference in backup speed.

Test1: We backed up a Mail Exchange server (VM) with VM snapshot:

SnapshotVM.JPG
Test2: With Storage backup

but the result was not so different

SnapshotStorage.JPG
I believed Test2 should have quicker time (based on the article's suggestion)? Could you please explain and suggest? Many thanks as always!

Environment: Vsphere 6.5, Veeam B&R 9.5 update3, Win Standard 2012, MS Exchange 2016

I would like to use VMST Tool service in order to update patches on virtual machines that are offline within the Vcenter infrastructure.
My main questions are:
Can the VMST service tool scan missing security patches in a offline VM?
Does this tool generates reports from the scans?

Thanking you in advance for your support.

Hi Experts,

       I am working on an web application (wagtail cms) like django-cms, which is in aws ubuntu.  Its backend is postgres, with elastic search few modules reactjs and nodejs.
The application is deployed in docker containers.  uwsgi is the upstream server for nginx.

      I get lots of errors with npm build, i am not able to run the application.  sometimes ports are not accessible. postgres is using 5432, elasticsearch is 9200. react is rendering on 9009. I get lots of dependencies error.    At what situation I have to use dockers?  sometimes I get errors in nginx configuration. could please tell what is good practice for npm build, run deploy.  

    What is the best way to architect the development and test environment?

    Will I be able access the postgresql, elastic search and nginx in linux ubuntu on aws with cms source code and contents on windows local pc?   or having the copy of postgresql, elastic search, cms contents and nginx all on a windows pc as development environment environment.   Elastic search has huge data.  and how to deploy the application on dockers in linux environment.

    What is the best way to have a development environment?  what is best test environment

   could you please tell me on how elastic search data is stored on postgres and what is network host setting in elastic search how it accessed from outside application.

    Could you please throw light on how to create development and test environment.

VMware server powered off and no longer will power on.

Receiving the following error: "Virtual Machine disks consolidation is needed"

My datastore is 2.0TB, and even through my total storage is about 1.5, the summary of my storage shows that the non-shared storage AND the used storage are both at 2.0TB (with 8mb free).

I have no snapshots -- I did a delete all in the snapshot manager a few days ago and they cleared out (after a few hours).

A couple days later, I'm finding myself in this situation with a full datastore. I checked the datastore and I do have some 000001.vmdk that seem to mimic the 01-1 (etc) vmdk drives.

I'm unsure of the dangers of running the consolidation. Should I proceed?
