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.

following is my Hyper-v Host configuration.

Hyper-V host running on SSD M.2 and all my VM  VHDX files sitting on local drives (4 x 600 GB Hard Drive - SAS 15K - 3.5" Drives in Riad 5).
I have Two Guest VM's (DC & file server).
I have configured a separate hard disk VHDX (1TB DYnamic) for DATA and attached to my file server.
Then I started transferring my old file server files to new File server DATA Disk.
While transferring data I couldn't access the new file server. The server was in the hung state. But i cold access my other VM which is DC without any issue.

Did the following tuning on Hyper-v setting

Disable VMQ/Enable Jumbo Frame/Disable IPV6
Separate NIC for Management OS and Team NIC for VM's

Veeam issue:  Using Veeam 9.5 and I've built a replication job on a VM.  The replication is a new build.  The VM is not replicated and it does not have any snapshots.  This is basically a new build on a replication job.

The job is failing with the error: unable to access file snapshot.  nothing else.

The VM does not have any snapshots and google isn't showing me much.  normally, solving Veeam issues is fairly straight forward, but this one has me licked.

Anyone got any ideas?


Disk ManagementHi,
 I have a virtual machine running Windows 2003 server standard. It has C, E and F drive. C and E drive is on the same disk 0.
 I like to allocate more space for E drive. So I increased the hard disk size in virtual machine/Edit settings by 11GB for testing.
 When I run DiskManagement in Windows 2003 server OS, I see 11.66GB free space next to "Local Disk )E:) 39.04GB.
 When it is all done, I like to see E drive showing 51GB.
 Is there a FREE software out there that I can use?

I am using a Promox VE on my local ML110 xeon 28GB 480GB SSD server. and wish to backup on my Qnap TS-253A 8GB ram nas server.

Normally I log into the local server with: URL: user id: root and then the password. but when I try to log in, it's not working: 

I downloaded nakivo for the backup.
I am trying to understand Azure Hybrid Benefits for SQL and the payments better.
It is my understanding that if I pay for a VM image w/ SQL server built-in, it's automatically counted as eligible for Hybrid-Use-Benefits(HUB). So, I would essentially be able to get the 30%+ savings just by deploying the VM and checking, 'I Have a license'.

Another way to ask this; if I deploy a WIndows 2016 Server w/SQL 2016 VM, does it come with Software Assurance, therefore allowing me the Hybrid-Use-Benefits pricing?

My CSP is saying I can save a boatload on SQL server by using Hybrid-Use-Benefits but I don't already have a license. They state that the way I am thinking is strictly for on-prem and doesn't apply to Azure! Then why have even have H.U.B. as an option?

Or is there another way to get the discounted pricing?

Do I really have Software Assurance since I lease the VM? Now this renders me available to utilize Hybrid Use benefits because I have Software Assurance?

It just seems redundant and it feels like I am missing something.

Xeon E2136Xeon SilverHi,
 I am looking at two separate servers that come with two different CPUs (please see screenshots for details).
 When I compare Average CPU Mark, E-2136 @ 3.3Ghz with 6 cores has 15,338 compared to Xeon Silver @ 1.80GHz with 8 cores that has 10,883. But the price of E-2136 @3.3Ghz  is cheaper than Silver @1.8Ghz. I am going to set up Hyper-V server with two VMs (one VM is domain controller and the other VM is Terminal Server running Quickbooks with 2 users and MS ACCESS database accessed by about 8 users via Remoet Desktop Connection. Btw, MS ACCESS database will be converted to MS SQL database at some point)
Here are website links for the screenshots:

 When you look at CPUs these days, they have so many varieties and down right confusing.
 Which CPU is better and why?

I have Veeam backup and recovery and was wondering why I received the email message after I added disk space to one of my VM's using VMWARE.  I added 50 GB and then rescanned the drive and increased the drive space.  Does it always delete all restore points when you do this?  I thought I've increased disk space before in VMWARE and did not see this message.
Dear Experts, we purchased Disk enclosure HPE 2050 yesterday to expand the storage capacity of SAN storage controller HPE MSA 2040.

We connected 1 SAS cable from OUT port of 2040 to IN port of 2050. After that, we turned on the 2050 device and add disk group, built RAID6 but it seems like take longer time than expected. Moreover, we got the "Degraded" status on Disks information, so is it normal? Can you suggest please? Should we connect the other SAS cable between 2 devices?

VMware displayed fan hardware error message but HP Proliant never ever shows any diagnostics errors when running the full hardware diagnostic at boot.  We have had periodic issues of server shutdowns a couple times a year w/ again no diagnostics errors but this particular one caused a couple virtual machine to get really corrupt to the point we had to perform a Veeam restore.  Anyway, here's the message below from VMWARE about a hardware fan issue but I don't understand why I can't any event logs or diagnostics to reveal a fan error too.  I ripped out the chassis panel and all four fans are blowing hard, no signs of slowing down.  I really don't this type of corruption to happen again causing catastrophic to their most application in the environment.  Any ideas of what needs replacing?  Is this masking a motherboard issue?   I am purchasing 4 fans that are not HP as a start. HP stopped selling for this particular Proliant unit.

I got a big problem with vmware workstation 12.5.9 build-7535481:

In snapshot manager I wanted to delete a snapshot.

A message has occourred that there is not enough disk space to do this.

Now the snapshot is not longer visable in snapshotmanager.

The snapshot is not visible running:
C:\Users\hhussy\Documents\Virtual Machines\MONTEVELO3>"c:\Program Files (x86)\VMware\VMware Workstation"\vmrun listsnapshots montevelo3.vmx
Total snapshots: 0

The snapshot-chain seems to be fully functional, because the virtual machine is running correctly.

This is in planning to setup a new VMware-base virtualization that comprises of 4 ESXi 6.5 hosts. All of the current physical servers, some SuSE and remainder MS Windows servers have to be migrated to virtualization. There are few pair of dual-host cluster using MS Windows clustering with shared storage. I heard that you actually can forget about migrate the clustering functionality, indeed, use the VMware's features, such as (but not limited to), HA, vMotion, or even vsan, and other; to "take over" the ms clustering.  Is that true? What would be the best choices to migrate this dual-host MS Windows Clustering into VMware virtualization and how?

thanks in advance
Is there a way to determine which VMs on a host have a CD drive connected besides going to each VM? A host here will have between 40 and 150 VMs so it's a pain to go to each VM.

My reason for this is that when I do upgrades I need to put the host into maintenance mode and undoubtedly there will be some using a CD drive. This prevents vMotion but I don't know until the VM list shows the VMs left that couldn't be migrated. I then need to go to each one and see if it is due to the CD drive. Once confirmed, I need to disconnect the CD drive to continue.
Hi All

Hope someone can help me. I have a server running with Hyper-V Server 2012 with a Windows VM running on it.

I need to be able to redirect the physical COM port of the server to my VM.

How does one go about doing that?
Have a failing cluster disk with an Exchange 2013 CU16 Std VM on it. Pool will not rebuild on new disk and will only attach if the failing disk is in the array.

Storage was reporting no errors and only found due to failing backups, so backups are not current.

I have decided to install a new Exchange box and attempt to move the mailboxes. Issue is I onlu had access to Exchange 2013 SP1 and CU21 and the failing server is CU16 which is not available.

I do not want to even think about attempt installing CU21 on the failing space. My question is whether it is advisable or is a problem to install CU21 on the new machine and migrate the mailboxes with the version mismatch.

I am stuck, storage will not stay stable for backups, VM moves, or even attempting to copy the vhdx. I know the mailbox moves are high I/O but I don't seem to have a choice to to attempt it.

Will the 16 - 21mismatch be a problem?

I have 6 Active directory server (windows 2003 SP3) in 3 different locations (2 servers each site).
They are VM, VMWARE 5.0.  
Friday 4/1 the VM's storage has crashed and I must restore the image of Server-AD1 and Server-AD2.
But now both server do not work: there are several error  in AD service ID1308 and Reply service ID13508.
I tried to resolve with repadmin /removelingeringobjects command but without any result.
Could you help me
Storagepools vs Raid 10.
Hi. We are setting up a physical server (not running Hyper-V) to act as a Domain controller and a SQL server.
Plan is to use 8 x 600GB drives (SAS) sat up in Raid 10 (using onboard Raid controller - HP ML 350 Gen10 server)
Divide in 2 partitions C: for Win 2016 and D: for SQL data.

Not familiar with storagepools.
Is an option to use 2 disks in a mirror (created on raid controller and create a Storage Pool in File manager after windows is installed.
Looking for max r\w but also safety in case of disks crashing.

This setup may also be used for single Hyper-V host as well?

Happy for any suggestions

I'd like an expert to confirm that I am able to reboot a VMware Horizon View vCenter appliance without affecting operations of the four hosts it manages or the 80 or so virtual desktops in use.

I am doing this in an attempt to troubleshoot logging in as root. There are 12 failed login attempts recorded. The password in the company's password safe is not working. I tried 5 or 6 times (a few different passwords after the one in the safe didn't work) and a colleague tried as well, thus getting us to 12 failed attempts. I am following the directions here as this vCenter appliance is 6.0. Though not vRealize Operations, I suspect the steps are the same.

Further, I am trying to login as root in order to run a shell so I can check the VMware vCenter workflow manager service and also disk space as a new vm pool I created fails to power on any of the new VMs and gives an error stating a general system error occurred connection refused. Troubleshooting that error led me to the aforementioned service and disk space as possible issues but need a shell to get that info. I am not able to run shell as administrator (receive permission error after successfully logging into the appliance with the administrator account). Then, if it ends up being one of those causing the error, fixing it so I can power on these VMs.

Whew, anyway... thanks.

I'm upgrading a cluster of hosts to 6.5 and wondering if it would break anything if I rename the cluster to 6.5. At the moment its 5.5?

Its an easy process, just wondering if things like Veeam backup will stop working

i have a virtual machine within Azure which serves up a web site.

when i navigate to it works fine.  i purchased a SSL certificate and it imported into IIS.  i edited the bindings for the cert using the default port of 443.  i added the site's name to the bindings.  

when i navigate to i get a "The connection has timed out" error.

the firewall rules allow 443 (default rule).

what else can i check and/or modify within IIS or the OS?  any help is appreciated.


I have a question regarding VEEAM Backup. We have many vSphere VMs which have terabytes of data. The typical backup strategy is to backup the VMs to disk and afterwards to tape as I know. We have enough space on the backup server to store the full backups but not for the incremental.

So I want to store the full backups on tape and afterwards delete it from the backup server. But VEEAM can not find the full backup anymore, so it starts a full backup instead of the incremenal. Is there a way to achieve what I want or are there any better strategies?

Any suggestions? Thank you in advance.
