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 - we have a 1TB large VM sitting on a particular LUN that needs to be rebuilt.  The LUN is using too many disks and the only way to free up some of those disks is to rebuild the LUN - which means we have to move the VM files off of it first.  Due to not having any other free LUNs/disks available big enough to hold the 1TB VM, we need to download it to a portable 4TB Passport USB drive.  What are the recommendations out there as to how to do this?  I know that I should be able to Browse the LUN and just download the files onto the Passport - but is that the best way to do it?  Should I do a LUN copy or something else, for any reason?

Thanks for your help.

Prepare for your VMware VCP6-DCV exam.

Josh Coen and Jason Langer have prepared the latest edition of VCP study guide. Both authors have been working in the IT field for more than a decade, and both hold VMware certifications. This 163-page guide covers all 10 of the exam blueprint sections.

Ok - This is how my week is going, need to see if it is OK to uninstall Exchange 2013 from Server.

Created New VM and installed Exchange 2013
Got to the point but did not do it, where I recert the New Exchange and the old Exchange.
I did do a Domain Prep/ ADPrep so the Active Directory Accounts are there for the EX2013
I tried making a backup and it failed. Found out that the Dell Server has bad blocks on the Virtual Volume. Tried swapping Disks, still reports Bad Blocks on the virtual Volume from Dell and still cannot backup.
I then tried to Migrate from 1 ESXi Server to another, failed. (The VM is on local datastore)
Tried to perform VSphere Replication to the other ESXi Server- Sync is currently stuck at 19% for hours.

I am preparing to destroy the Volume created by the Dell RAID set, but before I do that, the 1000 Point Question:
Since Exchange 2013 currently does not have any mailbox's and Exchange07 isnt really talking to the 2013 Server yet, is it safe to uninstall Exchange 2013 at this point and remove from Domain?
If so, then I am going to Destroy the Volume after that, and install a new VM Exchange 2013 Server and use that one.
I am pretty sure that the only thing affected was Active Directory, which has the new Exchange Accounts.

Good afternoon,

Running a test recovery plan in Site Recovery Manager, one of my virtual servers throws the following error:

Site Recovery Manager Error - An error occurred while communicating with the remote host

The next Saturday to migrate my servers from my alternate site to the main site again, this error would affect my live replication somewhat.

Stay tuned to your comments.

Regards...

We have an SBS Server 2008, Server 2012 R2 Physical (DC) and Server 2012 R2 Virtual (DC) in my environment. I recently converted the SBS server to a virtual machine in order to reuse the hardware. The conversion was successful. I then pulled a full backup of the SBS as a VM BUT I forgot to change the Symantec/Veritas Agent to the virtual machine agent. Now 4 days later (and at least 3 reboots) the SBS VM won't boot. It BSoD in Normal, Safe or Last Known Good modes. Thankfully because I am working on decommissioning the SBS most operations are no longer running on it. I attempted to build another SBS 2008 VM and restore the BE backup but it continues to fail because I cannot name the new SBS machine the same Name/Domain combo, and Backup Exec saying the restore resource cannot be found. So, the real question is: do I really need to worry about bringing the SBS server back online, only to decommission it? Exchange is already Office365, I have another physical DC (now running on the original SBS hardware), my certificate infrastructure was rebuilt using another server and I'll get over not having the SharePoint data (wasn't mission critical). Can I move the forest/domain operations masters with it offline and what other steps am I overlooking? Thank you in advance!

After an ESX host iSCSI became disconnect to our SAN's because of a Cisco switch issue, several VM's fail to power on. The error message is as follows.

Failed to lock the file
Cannot open the disk '/vmfs/volumes/5661e6ad-b2a8b7a5-a661-842b2b16cfbc/beta-2016/beta-2016_2.vmdk' or one of the snapshot disks it depends on.
Failed to power on scsi0:1.
Failed to add disk scsi0:1.

The referenced disk is a second disk on the VM. If i remote it, the VM powers on fine. If i try to add it back after booting up, same error.

I have also created a new VM from scratch with same specs and then added the OS disk and the above disk partition and get the same errors.

Hi,
I am trying to call a powercli script to Expand the harddisk in a VM with invoke-command , the same script is working fine in powershell host mannually, but when calling from vRO, its showing that workflow is successful with green tick but nothing reflected in VM(Windows 2012 R2). Can anyone tell if there is alternate to do the same.

I had created a VM, then a checkpoint, but somehow it was deleted.  It was only a little test VM I had set up, no big deal to lose, so I deleted the VM from Hyper-V Manager.

Now, whenever I try to create a VM--*any* VM--it fails with a popup error:

popup
It doesn't matter what the VM name is, it always claims that the checkpoint %vmname%.vhdx is missing.

Example:

I try to create a VM in directory d:\vm\vms\ called VM-01.  I tell it to place the disk in d:\vm\vms\VM-01\vhd\.  I hit Finish.  It acts like it is creating everything, then I get the popup above.  The directories are created (e.g. d:\vm\vms\VM-01\Virtual MachinesError log reports:

'VM-01' is missing a checkpoint. The disk paths missing used to be located at: D:\vm\vms\VM-01\vhd\VM-01.vhdx. The system cannot find the file specified. (0x80070002) (Virtual Machine ID 24161C9C-6C8F-4015-A258-DC2B8D42C907.)

This will happen regardless of what I name the VM.  

Security on the directory:

SYSTEM:  FULL CONTROL
%MyDomainUserAcct%:  FULL CONTROL
%LocalMachine%\Administrators:  FULL CONTROL

I've removed/reinstalled Hyper-V, done a system restore to before the problem started etc.  Services are running and I am an admin on the machine.  I still choose to run Hyper-V Manager as admin and get the same results.

To make matters more confusing:  If I choose the Quick Create option it works just fine.  If I create a custom machine and place it in the same directory …

There is so many discussion about vCPU, logical CPU socket etc. I am not clear about the ratio 1:1, 2:1 etc.
We have a server with 2 sockets.  A developer asked me to configure a VM with 1:1 ratio not more than 2:1 for 4 CPU.
How do i assign the vCPU ? Do I put 2 core and select both sockets?

I have two 2012 r2 VM DCs running on a standalone Hyper-V 2016 host.  I set up remote management VIA PowerShell and Hyper-V Management console. I guess over WINRM with CredSSP.  Well everything was working fine (6-8 months or so now).  I all stopped a few weeks ago. I tried to pin it down to a security update but could not.  When I try to start a new PSSession or authenticate on the HVMMC I get an HTTP error code 403.  Everything I have found so far seems to be related to exchange and IIS,  neither of which are on these VM and the host is just Hyper-V it can't run anything else.  Also at the same time I could no longer check point my VM's which is required to work for my Unitrends recovery appliance.  It's like the entire management subsystem is broken.   I am still able to RDP into the host and manage the VMs with PowerShell but that's it...  I looked through application and error logs.  But I didn't see anything that appeared relevant to me...

NEW Veeam Agent for Microsoft Windows
LVL 1
NEW Veeam Agent for Microsoft Windows

Backup and recover physical and cloud-based servers and workstations, as well as endpoint devices that belong to remote users. Avoid downtime and data loss quickly and easily for Windows-based physical or public cloud-based workloads!

Good Morning,

Last Saturday, we proceeded to run our Site Recovery Manager vmware to replicate live all our servers from the Main Site to the Alternate Site, the migration was a success.

Right now reviewing the Site Recovery Manager of my site Alterno that at the moment is my productive environment, I could validate that at Array Based Replication level the following error:

Cannot find matching consistency group at remote site for 'RCG-PRO-BACK-CB'.
Cannot find matching consistency group at remote site for 'RCG-PRO-BACK-CB.r48367'.

However I run a Test Recovery Plan and in the report, no errors or warnings appear, my question is that if when I re-execute the migration to my productive site again, this error in the Array Based Replication, would it affect my replication at all?

Or should we validate our storage box.?

Similarly, append printer with the error.

Regards...

A physical server has 25 cores, it is possible to convert it into a virtual guest hosted in a VMware with CPU only have 8 cores ?

Actually the server is a AD users with simple file sharing.

Hi all,

We have a one-off backup of an Exchange 2010 server from around 40 days ago.

I have it running in a Veeam SureBackup vlab environment and need to retrieve some Message Tracking logs from it.  The server is configured to keep 30 days of logs.

I am finding that when I try and look at the message tracking logs they are empty.

I have a feeling that it may have something to do with either log truncation or the time on the VM purging the logs (the time/date on the VM updates to the current live time, even though it is a VM from 40 days ago).

Interestingly, if I use Veeam explorer to browse the vbk, the folder which contains the "Message Tracking Logs" doesn't exist, suggesting that it is probably nothing to do with the time.

Any ideas what is happening here?  And how can I access the logs?

We had a switch issue yesterday and since then, two hosts are unable to connect to our dell equalogics'. Six hosts are connected over iscsi with Dynamic Discovery with no problem. The other two hosts cannot connect to Dynamic or Static LUN's

I have rebooted the host, attempted rescans of HBA.

any thoughts. i have verified all CHAP credentials and everything are set correctly. the switch was replaced with the same exact switch configuration.

We have 1x Exchange 2010 with a Multi role (Hub, CAS and MB) on site and we have round 90 mailboxes connected to it.

We would now  like to create an Exchange replication to another site.  We have created a new VM with Windows Server 2008 R2.

What is the best way forward? Shall we install Exchange 2010 Multi role on this server? How do you setup DAG on it?

Citrix 6.5, web interface server 5.4

2x Citrix Web servers - both configured identically.  We have noticed that if you log into WI server 2 and launch the ICA session then it works without issue.  On WI server 1 it does nothing.

Both work in Chrome (prompts for ICA download so not automatically) and apps launch ok on both, just not desktops.

Externally these servers are accessed via the Netscaler and look to work without issue but the fact WI server 1 doesn't work locally is bugging me.  It generates an event ID 21002 every time a launch is tried - we have reset ASP.net and followed every KB and tip going but to no avail.....

Dear all,
How can I develop operating system like window,linux in userspace.

I think it is possible if I can load the elf file or .exe file in memory from userspace.
Just using any C/C++ compiler. No reboot,no floppy,no image nothing,no VM etc. What's your thought.

Hi Experts,

We are using Nakivo backup and replication(installed on a windows vm) and would like to use a remote esxi as a storage option for the repository to house backups,

We have a standalone Esxi host with no production servers running on it at the remote site and would like to use this host as the offsite storage repository.

How would I present/prep this storage for use?

Thank you

Experts!  I have two IBM X3650 M3 direct connected via iSCSI to a N3400 NAS running OnTAP  7.3.1.  VM Host server VH001 can connect to the N3400 Volume SAN001a.  Host server VH002 can connect to the N3400 Volume SAN001b.  But I’m not able to get host server VH00a to connect to N3400 volume SAN00b or Server VH002 connect to N3400 volume SAN00a.  I had VMWare support check out my ESXi settings and after a few hrs they concluded that the N3400 was not presenting itself correctly.  Any suggestions?  

I've attached snapshots of each controllers configurations.

Thanks!
