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.

Hello,

I am trying to deploy OVF template using web client error message

Status :Connection to the remote resource was lost. Check your network connection.

Target : esxhost25.XXXXXXX.XXX
Server : Vcenter20.xxx.xx

Does it mean vcenter20 server has issue accessing esxhost25 using port 9443 ?

Hello,

When we do ovf deployment, it will start to ask question, etc.. and will do fill it up as we needed, once it's done it will start to copy the VMDK file to ESX host, how does it work? Does it do SSH copy from source?

I have a workstation with two NIC the only use of this PC is for the vm

In hyper-v there is a option to optimize/maximum bandwidth for vm to designate one NIC for the vm only by not Allowing management operating system to share this network adapter

Is this option available with VMWare

I'm currently trying to get a Fujitsu fi-6130 document scanner to work in a virtual environment. This is my setup:

Hyper-V host running Windows 10 Pro
Hyper-V guest VM running Windows 10 Enterprise
Hyper-V guest VM running Windows 7 Pro SP1

On the host, I have enabled RemoteFX via Group Policy, and verified it is active through RSoP. The Fujitsu scanner drivers are installed on the host, and the scanner works properly. In the Hyper-V manager, I have a vGPU that can be used with RemoteFX, and have added that as an adapter to the VMs. When starting the RDP session, I can see the scanner as a RemoteFX USB device, and have selected it. But even after installing the drivers on the VMs, the scanner is not visible. It does not appear in Device Manager, Devices & Printers, and when I attempt a test scan using MS Fax & Scan, it tells me there is no scanner connected. I even went so far as to enable RDP redirection of RemoteFX devices on the VMs as well.

Everything I've read about it indicates that USB scanners should work through RemoteFX, but it's just not working for me. Am I missing something? If anyone has had success in getting this to work, I'd love to know how they did it.

I have been asked to migrate/update an Access/SQL Application so it can run in a VM Environment on a true SQL Server; I have a general understanding to get started, but this is my first VM project, so step one is to plan for the unexpected. I request that you treat me as a novice when making suggestions.

Rather than write a novel about the function of this Access/SQL Application and to minimize suppositions, I would rather respond to questions about it.

To start this off, here is the current configuration ...
Standalone Workstation
Windows 10 64 Bit
Access Pro Plus 2013 (Front End)
SQL 2016 Express (Back End)

What would be the best approach and what pitfalls should be anticipated?

We have a group of 2012r2 hyper-v servers, some of them in a failover cluster, some of them standalone.

I have a couple developers I want to give permission to open the hyper-v manager to restart their servers. I have given them permissions through GPO that allows them to RDP and open hyper-v manager to manage the non-clustered hyper-v servers, but the same permissions won't work on the clustered hyper-v servers, they get an error saying they don't have permission to connect to the servers.

I have a security group called 'dev_admin', and on the OU for the hyper-v servers I have a GPO that is giving dev_admin rights for Log in Locally, log in through terminal services, and under restricted groups have put dev_admin into the remote desktop users, and Hyper-v administrators, and to test I even put them into the builtin\administrator group for local admin rights (I don't want to use this except to test, but still no joy)

BTW the iscsi SAN machine is also in the same OU, so all the servers are getting the same GPO settings.

What am I missing?

One of our customers is having a complex (multi-symptom) issue with a Server 2008 R2-based VM running in Hyper-V.

Affected server: Server 2008 R2 virtual machine on a Server 2012 R2 hypervisor. VM functions as a file server, DC, DNS server, DHCP server, and application server (yes, we're aware this isn't a best practice, but we inherited it from another provider). Integration services are up to date for this VM.

Symptoms:

--Client PCs on both of the customer's network segments suddenly and randomly (morning or evening) all lose the ability to reach the server's file shares (all clients timeout trying to connect). App and system logs on the client PCs, file server VM, and hypervisor show no apparent problem. In fact, the file server can be pinged just fine from every workstation, and curiously, I can browse to \\PCname\C$ of each PC on the network from that server!

--When the VM is restarted, it hangs on "shutting down", and the "turn off" function in Hyper-V Manager must be used to power it off (we've waited 1 hour and then 30 minutes the first 2 times this happened). As soon as it is powered back on, Windows loads without incident, and client PCs can reconnect to all shares. The app and system event logs for the VM show the transition from shutdown to restart, but there's nothing abnormal noted.

--When this VM experiences the issue, no other VMs on the same host have problems (we have an Exchange VM, terminal server VM, etc.).

I should mention that…

We have a VMware environment which has 3 hosts and we have multiple production VM's. We are planning to implement an FTP solution where we will have the FTP running in our production VM on one of the 3 hosts and there is an associated gateway product which needs to sit in the DMZ to provide a safer way of communication to the FTP server from the outside world. I have seen some articles on the web but want to hear from someone with real experience in setting this up in their environment

My question is
1. Can we utilise the existing VM infrastructure and create a DMZ environment utilising the same hosts
2. What are the best practices for having the DMZ VM's alongside our production VM's whilst providing the separation and maintaining the security aspect of what is needed
3. Can we setup the DMZ VM's in this fashion and also gain the high availability function utilising the VMotion capabilities.

My HyperV host is licensed with 2012 R2 Standard, and my first attempt at installing the guest OS of 2012 R2 didn't go well, so I deleted it and started over. (I don't remember having to activate that one)
I have this VM all set up and ready for production, but it has a notification that it needs to be activated. Did I do something wrong? It will not activate with my original key either...

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

Mac OS on Virtual PC

Is it possible if yes how do I install a Mac OS on a virtual PC?

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?

The ultimate Citrix XenDesktop 7.x internals cheat sheet!

What if you have to shut down the entire Citrix infrastructure for hardware maintenance, software upgrades or "the unknown"? I developed this plan for "the unknown" and hope that it helps you as well. This article explains how to properly shut down and start your ENTIRE Citrix environment.

I'm looking at a single, physical Windows Server 2008 R2 server, that is running both Hyper-V (5 virtual machines) and SQL Server 2008 R2. Is this a supportable configuration. I saw a Microsoft article that said it wasn't, but it only applied to clustered environments...this is not one of them.

I have a single Exchange 2013 box running all roles on a VM. It’s been in place for years and we haven’t made any recent changes. I built a FrontendTransport receive connector to allow selected internal and external servers to relay anonymously. This has been in place for years as well and nothing has changed recently. In the middle of the day one day last week mail suddenly stopped relaying from internal servers and printers. Any servers on a different subnet relay just fine. Incoming and outgoing mail works as expected. When I point the internal servers to the outside IP address for the Exchange server, and add their external IP address to the relay connector the mail flows fine.

I used ADSI Edit to verify that Anonymous Logon had “Accept any Sender” selected. I have restarted the server and the Transport service many times and even deleted and recreated the receive connector. I cannot telnet into the server from the LAN either. I get a “421 4.3.2 System not accepting network messages” error. I can connect and send mail via telnet from the Exchange server itself. There is not any AV software installed on the Exchange server. I have tried turning off, turning on and disabling the firewall. I even created a rule to allow port 25 separate from all of the Exchange rules. I cannot figure out what’s happened here. Any help you can provide would be appreciated.

physical server to VM

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?
