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 need to create a volume with "Bytes per Physical Sector" = 512 so I can use it as the staging location for Backup Exec (using GRT -Granular Recovery Technology) to restore Exchange (physical 2007) mailbox / items. (I know this setup is old. We are migrating.)
GRT requires the staging location have the same sector size as the volume from which the Exchange log files were backed up.
 
To do that, I added a new VHDX to the Backup Exec server (a 2012R2 VM on 2012 R2 Hyper-V host) and then I issued  
"Set-vhd VHDname.vhdx -PhysicalSectorSizeBytes 512"
to change its Physical Sector Size to 512 bytes. I did verify using "Get-vhd VHDname.vhdx" that it shows PhysicalSectroSize = 512.
But to my surprise when I got in to the VM and issued the following command on an elevated command prompt:
fsutil fsinfo ntfsinfo D:  (where D: is the VHDX I just created)
it shows the "Bytes Per Physical Sector" = 4096

I'm confused... Why are they different? Did I miss anything? How to create a vhdx with "Bytes Per Physical Sector" = 512

I am still somewhat new to Virtualization and I am currently in the process of upgrading/expanding my VM server farm. I was going through some documents and in of the documents it mentions that I should have a separate disk array for each virtual machine on a multiple virtual machine system.

My question is what do they mean? I have a 6 disk server and would like it to host 3 VM's. From how I read the statement above I should configure server into 3 RAID 1 configurations where normally I would configure either a RAID 5 or 10 then split the array into however many disks I need for the 3 VM's.

What is the correct way? Right now I have all of my VM servers configured as RAID 5 the chop up the array into drives for the VM machines

Looking to expand hard disk on a VM running on VMWare Workstation 14. It has snapshots on it and I want to ensure all snapshots are retained. Is this possible to do and if so how? Thanks

SCOPE :
The following question deals with the bare metal restore of a Microsoft Hyper-V server running (amongst others) two virtual machines on which is installed a licensed Oracle 12c (Standard). I am not interested in an “Oracle for DR” installation scheme. There is exactly one backup scenario: the entire Hyper-V server is backup up to local media using Windows Server Backup. There are exactly two restore scenarios: (1) the entire server is restored on the original equipment  from backup media using the appropriate Microsoft Distribution Media and (2) a single VM is restored from backup media using Windows Server Backup.

Comment:
I understand that Oracle’s default position is that all installations require licensing. The first scenario above implies that more than one physical machine may hold the Hyper-V server; the second scenario implies that restoring VMs could create more than the two licensed installations. To quote a post by Brian Lowinger (https://www.softwareone.com/en/blog/licensing-oracle-database-for-disaster-recovery) : “Oracle uses the term ‘failover’ to describe a scenario where, within a cluster of servers, a database running on a primary server could move to a secondary server when the primary server fails. Oracle allows for the database to run on the secondary server for up to 10 days without additional licensing requirements.” If we stick to the scope of the question and the 10 days grace period, all licensing is honored.

What steps need to be followed to migrate Hyper-V virtual machines (that are currently running off a Server's C: drive) to a Storage Area Network (SAN) or to a different drive on the same server?

I want to migrate both the virtual hard drive(s) used by the virtual machines as well as the data and configuration files and folders.

Is the best way of doing this by using the "Export" feature within the Hyper-V Manager console or should a different method be used?

Hello,
2 hyper-v 2016 hosts.
Client wants me to set up replica between hosts.
Should I enable both hosts as replica server and than configure guest VMs on both hosts for replica
or just one host can be  replica(DR) server and other primary?

In this example one server is replica server and other primary
https://nedimmehic.org/2017/01/29/hyper-v-2016-replication/
What if I need enable replication for guest VM on replica server host.

Looking for a low cost spam filter in an exchange server.  I was wondering if I could use a Ubuntu VM on the Exchange box and if there were some built-in or open source spam solution that I could install on the Ubuntu VM to filter out the SPAM email before passing it along to the Exchange server.

Hi all.

I have a small script which I found and have used to encrypt Azure VM instances. Here it is - note, everything is hard-coded so each time I run it I have to edit the script. t Can anyone modify this so that when I run the script, I get prompted to add the names dynamically, so using parameters?

    $RGName = "MyTestRG"
    $VMName = "MyTestVM"
    $VaultName= "MyTestVault"
    $KeyVault = Get-AzureRmKeyVault -VaultName $VaultName -ResourceGroupName $RGName
   $DiskEncryptionKeyVaultUrl = 'MyVaultURL'
   

Thank you

Cloud Class® Course: Microsoft Windows 7 Basic

This introductory course to Windows 7 environment will teach you about working with the Windows operating system. You will learn about basic functions including start menu; the desktop; managing files, folders, and libraries.

Client has two XenApp 6.5 systems - 85 concurrent users across both. Both systems stable and users/client happy. Both running on Windows Server 2008 R2. Both systems working fine. However, during recent Support & Maintenance renewal of licenses, Citrix advised that XA6.5 is EOL and support will only be given at HUGE cost (honestly the costs are nuts).

All servers physical. both systems hosted separately in separate countries. Both have NetScaller VPX in frount of them. They do have VMWare hosts to leverage off but ideally Citrix servers need to remain on that physical hosts they have. They have licenses for Server 2012.

So what I'm asking is:
  1. What is currently supported version of XenApp
  2. Is their an upgrade path from XA6.5?

Lets start there!

Thanks

MVMC - Warning before runningMVMC ErrorHi,
  I am getting an error "The operating system of the VMware VM is NOT SUPPORTED.  This does not prevent conversion, but no support is provided for this conversion" when trying to convert VMWare VM running Windows 10 OS to MS HyperV Server using Microsoft Virtual Machine Converter program.
 Is Windows 10 OS not supported by Microsoft Virtual Machine Converter program?

Need a little help with  a powercli script to power down a VM wait for it's state to change to powered off, wait another 15 seconds, and then make changes.
I can do this a little more easily with shutdown-vm. But that's hard on the OS, so I am trying to get a clean shutdown with shutdown-vmguest. The issue is I can't get the part to check the powerstate right. Here is what I have tried
$vmname = read-host "Enter VM name here"

get-vm $vmname|ft| where-object ($VMName.PowerState -eq "PoweredOn")

   Write-Host "Shutting Down" "$VMName"

   Shutdown-VMGuest -VM $VMName

   #Wait for Shutdown to complete

   do {

      #Wait 5 seconds

      Start-Sleep -s 5

      $status = $VMName.PowerState

   }until($status -eq "PoweredOff")

Start-Sleep -s 15

write-host "$vmname has shutdown. It should be ready for configuration."

vCenter was telling me my username/password were wrong.  I rebooted it, and now I am getting error in the attached screenshot (in short "server could not interpret the client's request... returned 503")

Any ideas?

I have a client who runs a franchise and the software provided by the franchise only works on Windows XP. At the begining of the year we replaced their workstations with Windows 10 PC's running virtual VM ware with windows XP which is running fine. The file server is running windows 7.

As it is now time to change the file server we relaced it with a Windows 10 Maching.

The problem now is the Windows XP machines wont find or map a network drive to the new Windows 10 maching although I can ping it from anvirtual XP maching.

All firewalls are disabled and in network and sharing centre network discovery is enabled.

I have a (hopefully very simple question) regarding routing in a hyper-converged environment. In the simplest form, let's say we have a single HC node (HyperFlex, SimpliVity, etc.), and the VMs being hosted on this node are within a typical Web/App/DB hierarchy - so, all in different VLANs/subnets, virtual firewalls in-between, etc.

Given the above, would communication between the different tiers (W/A/DB) require exiting the HC node to an external routing device, or would the virtualization hypervisor somehow be able to handle this? (Let's assume NSX is off the table.)  This would seem to be a "normal" deployment for any HC environment, in that the more condensed the environment, the higher demand for internetwork connectivity.

I'm trying to get to whether a Layer 3 physical switch is "normal" for these environments to handle this inter-tier traffic, or if there are more efficient options.

Thank you

Using VMware 6.7
- having problems moving VM from local storage to LUN
- tried Quick migration and vm copy

using Veeam getting errors:
1 . Processing BWSUTL01 Error: Object reference not set to an instance of an object.       00:48 (using vm copy)
2.  Processing VM GESUTL01 Error: Cannot migrate VM GESUTL01. VM virtual hardware version is incompatible with target vCenter or ESX(i).        00:18 (using quick migration)

Hoping to not have to manually copy files, if possible.

Hi Experts,

We need to move our Esxi hot 6.0 to a new location. The host has 2 VM's and ion Vcenter cluster. The host does not have Vmotion or HA.

I plan on shutting down the 2 hosts both Winodws boxes by the normal shutdown of a Windows server and then shutting down the Esxi host in Vsphere

Would i need to put the host in Maintenance mode first? And would i need to use Vcenter to shutdown the host or will Vsphere work the same?

Thank you

I need to install a hyperv VM.  The OS has been copied to a folder on the host server. It is not an ISO image. I can't see how to install the OS on a VM using this folder.

We have a Vmware esxi host with a single VM. We need to connect this VM to two different networks. I created two vswitches to accommodate the setup.

Vswitch 0 - 192.168.1.2
Vswitch 1 - 192.168.2.2

NIC 0 - 192.168.1.10
NIC 1 - 192.168.2.10

Vswitch 0 is connected an araknis 24 port switch which is connected to our main network. We are able to get DHCP and get to the entire network no problem

Vswitch 1 is connected to a Linksys VPN. This VPN has 2 VPN Tunnels with existing devices and are able to communicate with each other. The VM receives a DHCP address from the VPN no problem. We are able to ping the VPN gateway but unable to ping or see anything locally or through the VPN tunnels. I also disabled the NIC 0 to make sure traffic wasnt being sent over the wrong NIC.

I have a Hyper-V base server that has a total of 24 processors.

Is it possible to assign more than 24 total virtual processors among the Hyper-V virtual machines?

In other words, can the virtual machines share virtual processors?

we have production vm  The vDisk images are being hosted on the Provisioning servers. They conform to the following naming convention: data1 and data-Test
The VM’s and images can be interchanged via the Provisionoing Services Console on either PVS server.
The vDisk files can be found on the D:\ drive in the root as well as in the PVSStore directory.
The vDisk files in the root of D:\ are not active. They are the base images . The vDisk files in the PVSStore are the active files. The *.VHD files are the base image files

so when I use deployment method for office 2016 and OCT method, will I need to deploy office 2016 as an image (what does this mean) and not setup.exe  on the vdisk image?

directly , our Hosted shared model which is based on a server based operating system.

how installing on vdisk image will populate office 2016 to machine catalog and delivery group, I just need to know basic architecture.

I used Microsoft Link to configure my clock on the domain controller to which the 3 others point to. I rolled back the clock so that all 4 have the same time (3 minute difference) and ran the tool. I entered pool.ntp.org,0x1 in the settings for the server.

Checked after a while using w32tm /query /peers on the source domain controller, got the following:
C:\Users\administrator.AD01>w32tm /query /peers
#Peers: 1

Peer: pool.ntp.org,0x1
State: Active
Time Remaining: 705.1104493s
Mode: 1 (Symmetric Active)
Stratum: 2 (secondary reference - syncd by (S)NTP)
PeerPoll Interval: 6 (64s)
HostPoll Interval: 6 (64s)

Checked on the other domain controllers (which pointed to it for time):
C:\Users\administrator.AD02>w32tm /query /peers
#Peers: 1

Peer: SERVER01
State: Active
Time Remaining: 239.9177806s
Mode: 1 (Symmetric Active)
Stratum: 3 (secondary reference - syncd by (S)NTP)
PeerPoll Interval: 10 (1024s)
HostPoll Interval: 10 (1024s)

The time was OK yesterday when I left. This morning the clock rolled forward to the same as yesterday, 3 minutes ahead.

What else can I check? This server is a VM on VMware 5.5 and have the "Sync with host" unchecked.
