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.

I have a Windows 2016 Hyper-V manager with two guest VMs. One guest VM is a Domain Controller and the other is a SQL DB server which is a member of the domain.
The Hyper-v server is in a Workgroup. Should I make the Hyper-V server a Domain Controller for a separate domain and then make resources such as a NAS, members of that domain?
I'd like to access the NAS from the Hyper-V manager for VM builds and Disaster Recovery and I'd also like to access the NAS from the Guest VMs for software images.

I setup two Windows Server 2016 VMs, one of which has the Essentials Role enabled, and the other VM will be a database/file server.  I joined the second VM Windows Server 2016 Standard member server without using the http://servername/connect option, and the Essentials console does not show as a connected host to the AD Domain.  I joined the member server the regular way by using System\Advanced  System Settings\Computer Name Tab, Change Button\...

So it joined the domain without issue, and I am just wondering why it does not show up as a server within the Essentials console.  I've done this same thing on SBS2011/SBS2008 and I followed the same steps above and the server appears within the SBS Console.  

I just want to know if Essentials works the same way or not, or whether additional servers simply do no the display the Essential console.

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).

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

Hi,
The current VM server is started and it does go into Recovery mode. Since it is being started by console, is there a way to put also "F8" into the console command, to ensure that "F8" would be executed, when starting the VM server?

Would that be possible to set the RAM threshold limit in VM? In the VM its showing only 8GB but system engineer says "You guys are using  5GB RAM now, so when you get to 7GB it will automatically start up beyond 8 to whatever you need up to 24.5gB . Now It is set to 80% thresholds"

I am installing vCenter Server on windows and connecting it to an external SQL database.  Somewhere in my installation I must  have entered a local administrator account and it is being used to create a new data source.  long story short I get the attached error.   I am wondering if this default account can be changed so i can connect using a domain user account.

Thank you.

Hi,
 
 I have a Hyperv virtual machine  computer where the hard drive size is 1.4TB, but with only 19GB of free space. However when I open the C drive and select all the foloders in the root directory of C drive, I see 868GB in size including 18GB Paging file. So  if I do the math, I should see almost 500GB free space. But it only shows 19GB free.  I also discovered that space allocated for Shadow Copy Storage is about 40GB.
So there is something that is taking up space. How can I find out?

Thanks.C DriveC-Drive-Folders.PNG

Hi experts,

I am using Microsoft Azure, which comes with my Partner subscription. I am only using it to set up simple storage under the $100 monthly limit to use with Veeam. The problem is when I set up a simple storage, Veeam does not recognize it during its wizard. If I set up Azure to run the storage as a VM network, it does work with Veeam, but it is too costly, and it is complicated.

Basically, what I am saying is that I am rather clueless when it comes to working with Azure. I am not sure if I am able to contact Microsoft for support; that is doubtful. If someone understands my question, then possibly it can be done here. If not, I may need help one on one remotely to set Azure up properly.

Thanks.

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

I have a question about a RAID6 configuration with (8) 600GB 10K RPM drives on a Dell PE330.  The T330 chassis can accommodate up to (8) drives.

RAID 6 is just fine for a virtualization stack. Many questions answered here: Some Hyper-V Hardware & Software Best Practices.

Two RAID 6 logical disks: 75GB for host OS and balance to guest data (RAID 6 6x 900GB = ~3.5TB)

Once the host OS is in set up the second partition and once the Hyper-V Role is set up make sure to set the configuration and VHDX file setting to that partition.

I believe in order to setup each RAID6 logical volume it requires at least (4) drives.  So, how does the above recommendation make sense.  I am just trying to understand the premise.

Are we saying, setup  each RAIbD6 logical array with (4) 600Gbs disks which would provide approximately 1.2TB of storage each.  That does not make much sense to me if that is the case.  Placing hyper-v os on the first logical disk use no more than 100Gbs of storage.  Trying to make sense of this response.
 
I looked at the following article about RAID6 logical disks:

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 have a management console on a Windows 7 VM. I need to create on for a new site. The software is exactly the same, just needs a IP change and a few configuration changes to create on for a new site. Can I copy the VM I have an reconfigure it for the new site. It will set on the same Host. I know how to import and export the VMs but not sure what I need to do for the domain to see it as a new PC. Please advise. We use Windows Server 2012 R2 standard and Hyper-V.

New creating VMs so any recommend links would be appreciated as well.

http://backupchain.com/i/dynamic-disk-hyper-v-backup-considerations

I was reading the above mentioned article, and it appears to suggest not using dynamic disks if at all possible.  It suggests not using dynamically expanding disks because of reduced performance by increased overhead and fragmentation.

I usually assign the guest VM OS as a fixed disk.  This also applies to virtual disks with databases.  However, for growing company file storage, I usually assign the virtual disk as dynamically expanding with a cap imposed.

I will be installing a new Windows 2016 hyper-v server with two vms.  On one of the two vms I was going to assign the guest os (80Gbs) and a database virtual disk (150Gbs) as fixed virtual disks.  Their company data is currently at 330Gbs, and growing, and I was going assign it as a dynamically expanding disk with a cap of 800Gbs.   As a rough estimate the amount of disk space will probably double within 4 or 5 years.

After reading this article, I may want to consider assigning this virtual disk as fixed (800Gbs), and be done with it.  I understand, a large fixed disk has drawbacks when it comes to moving/restoring the entire drive should that be necessary.  However, fragmentation is just as an important issue over the near/distant future.  Also, I purchased this server with a more than adequate amount of overall disk space to last many years, so disk space is not …

Please excuse the basic question, but I'd love to have someone just spell this out for me.

I wish to install a terminal server style of installation where I have virtual images of either a personalized-to-the-user-profile version of Windows 7 desktop or a generic Windows 7 desktop that resets after each use. I cannot use the server desktop as a OS as we have some legacy software that won't run properly through a server OS.

I feel like this is called VDI, but every time I pursue information on a XenDesktop or RemoteDesktop solution and how I'd go about it, my readings suddenly shift from what I am envisioning to a solution based off of using a server desktop. I am sure I am missing something, so I would appreciate if someone could just point me in the right direction.

I want this to serve as a utility for remote users now, but also to double as something I could restore at an off-site virtual farm to provide desktops for our users in the event of a disaster. (I am already set to restore my VMWare based servers in this way) I thought that logically this would best be done with the VMWare virtual desktop, or Citrix Xen Desktop, but I would love for someone to tell me where I am going astray in my reasoning and point me in the right direction of research.

Thanks for your help!

I use Veeam Backup & Replication to Backup all my VM's and Replicate them to my DR site.

I'm currently Replicating from a the live VM's.  I would just like to know from best practices should continue to Replicate from the live VM's or Replicate from the last Backup of the VM's?

Thanks.

We are looking to set up a point to point vpn with sonicwall on our end and watchguard on the clients end. We'll be using that to set up crashplan backup on virtual machines. Two questions.
1. Is it pretty straightforward to set up the point-to-point between sonicwall and watchguard?
2. Once that is established, would we need a backup device for each VM (say we have 3) or would backing them up to one device with designated partitions work ok?

Hi,

I am  new in SCVMM  ( hyper-v ) and comes from VMware background. i have  recently been tasked  to create to development server from critical running VM's  in cluster environment.  i have looked into this but cannot find snapshot operation the reason we are using System Centre 2012 Virtual machine manager where it only gives option for checkpoint.
 My question is  checkpoint is similar to snapshot and how  I can safely  create two development server using   Two live production VM's ,.
Please can any one expert on hyper-v en light  best way to achive this.


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.

We are attempting to deploy a second Subordinate Certificate Authority in our domain. I am doing this because the original subordinate was deployed on Server 2012 R2 Standard and we have a project that requires NDES. NDES requires Enterprise or Datacenter. So I spun up a new VM and started by installing the CA role, I requested a certificate from our offline root and issued the certificate as well as downloading the CRL and saving it to the CertSrv folder. However, when I installed the new certificate on the second Subordinate CA I keep getting the following error message:

The revocation function was unable to check revocation because the revocation server was offline.

So I went back to my Root offline CA and it shows in CDP that our First Subordinate CA has the CDP set to it.

My question is do I just need to issue the same certificate that I issued our original subordinate CA to be able to get the new one up and running?

I plan to reuse an OS VM image for multiple different local computers. I'll be using a Linux guest OS on low-powered x86 hardware. Assuming I understand correctly this sounds like a job for a bare-metal hypervisor. Is there a particular hypervisor you would recommend? I would prefer something simple and free. If you have any links to setup walkthroughs those would be great too.

Hi
I am moving a VM from Datastore-A to Datastore-B. Before I migrated to a new store, I powered off the VM and I them I right clicked the VM and clicked Migrate and it is taking long time to migrate and it has progressed only to 50% after 20 hours and now I am thinking to cancel the migration.

In the Vsphere Console – Recent tasks- Relocate virtual machine- If I right click this task I get an option for Cancel.

If I cancel, will any corruption happen and end up with a problem.
Please suggest.
Thanks
