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.

When you export a VM in Windows Server 2012 Hyper-V, does it export the VM and ALL checkpoints with it?

When I import the VM later, will it have the entire checkpoint subtree in the imported VM?

Hi All, i am consider the new Veeam Backup & Replication 9.5 package at a site with two Host servers.

I have a pretty simple question that i cant seem to get an answer for, the Failover procedure is pretty straight forward and easy if i need to take the Source VM offline or its corrupted, my question is this, how do i get the Replicated Target Host VM online in the event hardware failure on the Source Host where Veeam is installed, if the Target Host has failed and i have no access to the Veeam console, how do i get the Replica VM online on the Target Host

I am sure there must be a simple solution, just cant seem to find anything

Thanks in advance

what is the difference scsi and ide and what is scsi (0.0)...etc
In Windows Server 2012 Hyper-V, I deleted the checkpoint subtree for one of the VMs ... let's call it VM1.  I see the "merging ..." status when this is happening.

Suddenly all other VMs were automatically paused in "Paused-Critical" state, and I can't restart any of them.

When I try to restart VM1 it says:
Could not initialize memory: There is not enough space on the disk. VM1 failed to start.  VM1 could not initialize memory.  There is not enough space on the disk.

The Virtual Machine VM1 failed to start because there is not enough disk space.  The system was unable to create the memory contents file on "C:\ ... . bin" with the size of 4097 MB.  Set the path to a disk with more storage space or delete unnecessary files from the disk and try again.

Before I deleted the checkpoint subtree for VM1, VM1 has 13GB of free virtual space, and the host / physical server 38GB free space.  Please help.

      I have been asked to move a Terminal Server/RDP server that is a VM machine on a Server that serves also as a DC within two days! The server and their Dell Sonicwall TZ400 will be moved across the city to a temporary location but they still want it accessible to employees during the interim. Honestly, I am not certain what all settings I will need to change to point the employees to the new IP address on the sonicwall and server. I am aware they will need to adjust the IP/port on their RDP clients individually, but I need some direction as to what on the firewall and/or the Physical and VM server to make this work. I do have available static IPs at the new location.

      I have tried using the trusty Google, however I only find ways to trransfer license and CALs etc, but that is not the case. I am just physically moving the server and firewall from one location to the next with no hardware changes other than ISP/IP address. Any assistance is greatly appreciated.

Client is looking to have 3 separate locations connect to FileMaker databases.  Sometimes 2 users will want to access the same file.

Can they set up FileMaker Pro on a Virtual Private Server and use that copy to serve files?   What is the limit of open files for non-server FileMaker at the moment?
IF they purchased FileMaker Server, would that work?

Could they remotely run FileMaker on a VPS?

Is there a way to do this?


can we back up vm through veeam ? and
can we monitor vm through veeam ?

do we have both monitor and back up tools from veeam?

I need to P2V for few physical mahcines and I'm trying to save to CSV volume directly.

I can access the physical machine by C$ and access into CSV location but when I try to save disk using Disk2VHD, it says target has not enough space which is because it only detects the space of physical volume.

Anyone please advise how I can save VHD file location directly to CSV so that I don't need to save to disk first then copy over to csv (double work) ?

I have installed Server 2012 R2 and created 2 VMs (VM-1 a DC and VM-2 a member computer) both running Server 2012 R2. The test bed server I am using has 2-120 GB SATA SSD for the OS in a RAID 1 and 2-1 TB SATA hard drives in a separate RAID 1 configuration for the data storage. They are controlled by the Dell PERC card. I would like for the member computer, VM-2 to be able to access the data volume and see it as just another hard drive with a drive letter. This is a work in progress for me as I am learning and reading articles on how to do this. As a side note when I created the Hyper V folder (300GB) to hold the VM files, I was able to see the data volume from the Hyper V host and located the Hyper V folder there. I was not sure of how much space the VM files would require as the system space requirements grow. I would have preferred to locate them on the SSD...however.
On the member server VM-2, SQL Express, RDS and a business management application will be installed. It should have about 500GB available. All of this will be required to be backed up nightly. Your help and comments are appreciated.
Thanks - HBee3
Installed the PS-AutoLab, ran TEST-SingleServer and worked OK, then needed to run  POC-MultiRole
and CLi1 and Nano server finish OK but the DC1 and S1 are stuck on the black screen with the circle dots spinning for over 24 hours. I tried twice after a full reboot. No errors in the event log. I'm using Surface Pro 4 with 16gb or RAM and over 100GB of free space. Any idea where to look?

When I launch Oracle Virtualbox and leave it running with my VM Ubuntu instance, after some undetermined amount of time the machine will crash and stay powered off.

The only error message in Windows is an unexpected shutdown occurred.

Normal usage doesnt crash the machine, I do not get any warning that I can see when it occurs and I've run a few memory tests that all passed.

Any ideas?
I have a physical RED HAT 5.5 oracle server with 3 databases
the oracle partitions are like this

dev/sda3              /oracle
/dev/sdb3             /oracle/PRO
/dev/sda5             /oracle/PRO/102_64
/dev/sdb2             /oracle/PIP
/dev/sda7            /oracle/PIP/102_64
/dev/sdb1            /oracle/POP
/dev/sda6            /oracle/POP/102_64

I converted to a virtual machine with vmware converter but because its a production server I cant convert all sdb partitions where the databases are

so I only converted

dev/sda3              /oracle
/dev/sda5             /oracle/PRO/102_64
/dev/sda7            /oracle/PIP/102_64
/dev/sdb1            /oracle/POP
/dev/sda6            /oracle/POP/102_64

now in the virtual machine we resize sdb to "reinstall" sdb2 and sdb3 and it works fine
but the matter is that when I mount this sdb2 and sdb3 now sda5 and sda7
cant be mounted

mount: mount point /oracle/PIP/102_64 does not exist
mount: mount point /oracle/PRO/102_64 does not exist

but if I only mount this two devices they mount ok and if I then mount sdb2 and sdb3, sda3 and sdb4 disapears

df: `/oracle/DB2/102_64': No such file or directory
df: `/oracle/DB3/102_64': No such file or directory

Is there an special procedure in this mount piont cases or I miss something in the procedure?

this is the original server

[root@proddb01 ~]# df

Hey there,

We have so many Hyper-V servers in our environment. We do run into situations where a particular VM on a particular Hyper-V hangs. We would like to give limited access to support team so they can reset the hung servers remotely. I can find a script that can do the purpose but I want to make sure support can look into console first to determine if the VM is REALLY hung or there is some other issue (RDP ... etc) going on.

On VMWARE, its easy to tackle this. Anyone know how can this be done on Hyper-V? Please advise.
I've got a client with on-premise exchange 2013, running Outlook 2013 at their desk. They had the deadly update that got released in June and since then, cannot use search in Outlook, or search in webmail. His mailbox is about 120GB in size, so he is running in online mode. Prior to the update his mailbox was closer to 200GB, and everything was working fine in online mode. As soon as that update hit, it broke search, and uninstalling the update, has not totally resolved the issue. It also takes a long time to download an attachment from an email, which was not occurring before. The exchange server is running as a VM on a Microsoft Hyper-V server, and has 4 cores and 24GB of ram assigned to it, for a client of about 30 or 40 people. Here's what i've tried:

Rebuilding the search index on the server by stopping search services, deleting the index folder in the directory where the database is stored, and restarting the search service.
Creating a new Outlook profile.
Archiving out roughly 80GB worth of mail.
Uninstalling the problematic update.
Rebooting several times throughout this process.
Running Outlook in safe mode.
Disabling hardware acceleration in Outlook.
Updating the NIC card drivers.
Currently running an SFC scan.

I'm out of ideas. This was working fine prior to the update, so the size of the mailbox shouldn't be an issue, although it is huge. I also was able to archive out over 80GB worth of mail, and it still is just as slow as before. There are no …
1.      Each VM size comes with an associated disk.  For Windows Server is this C:\ or can it be partitioned into two drives?  If it cannot be partitioned, how do we add an additional disk to a VM using the online pricing calculator?

2.      The web application requires a filestore that is shared with a UNC path to all VMs.  Can this be achieved with ‘File’ storage type, or is a ‘S series Managed Disk’ recommended?

3.      The web app filestore will be 1 TB to begin, and requires the ability to grow over time.  Can storage be easily increased for both storage types in question 5?

Kind regards.  Thanks for your help, experts.
We have one VM that the system reserved partition (101 MB) is full which is causing any backup that includes system state to fail.

I have seen the discussions that say you can just delete that if you are NOT using Bit-Locker, but that is not true. The system reserved partition (when installing Windows Server OS if you do NOT delete it at the time of partition configuration) contains boot mgr files and CAN NOT BE DELTED.

Any help is appreciated.
Can you please explain me why VMware SRM replicated datastores named with the snap prefixes after initiating Test Recovery?

what are the devices can be added when the virtual machine is powered on ?
Dear Team, we have a project required some licenses, but not sure if we can calculate enough. So can you please help?

We will have 4 physical servers (running VMware ESXi 6.5 - each server has 20 cores) for virtualization. Inside them, we will set up 6 pairs of Window Server 2012R2 standard (for Active Directory and MS Exchange 2016 Standard Servers), serving about 2500 users in total.

So which license and amount will we need to purchase? Also, please suggest the Antivirus, Antispam sofitware for Exchange servers. Many thanks in advance.

Hi i work with vmware workstation and i had a problem, i want to connect between twoforest in vm so i used gns3 to connect between them with router and now i want to add a client into forests and i dont know how to connect it
Dear All,

I expand an Virtual Hard Drive from 300gb to 600gb and, after that, the replication stopped working.

What happen is that the replication VM, stops at the old capacity and don’t “update” to the new one.


VM – 600gb

VM – 300gb

I already tried this steps:

- Make a new Virtual Machine;
- Remake all the replication process;
- Expand the replica VM HDD to the new capacity;

Nothing worked.

The error in events is:

Hyper-V could not replicate changes for virtual machine 'SERVER': The request failed due to a fatal device hardware error. (0x800701E3). (Virtual machine ID ............)

Any clue?

Thank you very much.
Hi All,

2nd time retyping this as I hit the back button :/

I am receiving the following error:
The description for Event ID 32000 from source Microsoft-Windows-Hyper-V-VMMS cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

If the event originated on another computer, the display information had to be saved with the event.

The following information was included with the event:

Server Name

The locale specific resource for the desired message is not present

I have installed a new server running server 2012r2 on a customers site with a plan to replicate the servers to the new hardware. Switch the live virtual servers from the older hardware to the new hardware.
The 2 Host servers are running MS Server 2012r2
The 4 Virtual Servers are also running server 2012r2 (Two will replicate & two will not)

I was unable to replicate the servers from older host to the new host. So I decided to export then import the 4 virtual servers from the older host to the new host. Worked so all the virtual machines are now running on the new host server.
I then tried replicating from the new host to the older host. Failed again.
I decided to format then reinstall…
I have an Event Log question about vCenter 5.5.0.

I have a number of events in the middle of the night or either a user root@IPAddress or VSPHERE.LOCAL\administrator@IPAddress logged in and logged out as "Mozilla/4.0 (compatible; MSIE 6.0; MS Web Services Client Protocol.

The IP address referenced is a vm backup/monitoring server with Veeam Backup.

What I'm confused about is why it says "Mozilla/4.0". There's nothing connecting via Firefox, is this some other Mozilla process built in that I'm not aware of?
I cloned a Windows XP VM from my PC (running VMWare Workstation 12.5) and moved it to another PC running the latest free version of VMWare Player.

The OS seems to start fine in Player, but any time we try to access files (like opening Windows Explorer, for example) it takes a very long time.   WMWare Tools was re-installed in Player, just to see if that was the issue.    The new PC (Player) is actually a bit faster than the original PC (Workstation), and both 16GB RAM, so I'd expect no speed difference.

Any suggestions?
