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.

Simple question: I have been testing Hyper-V Server 2019 (the free barebone) and I cannot create more then 128 vm and I search and found no information that mentionne there is a limitation for that. They all say that as long has I have RAM I am fine and I have loads of them.
If this is the limitation, I will need to go back to Proxmox....

Thanks for the info
Hi Guys,

We've upgraded from VMWare ESXi 5.0 to ESXi 5.5
The VSphere client V6.0 no longer connects to the host.

Alternatively, I would like to upgrade to the free version of 6.5, but the website links doesn't seem to work.

Does anyone perhaps have a download link for the free version of 6.5?
Or a client which will work on ESXi version 5.5?
DC1 VHDX FileDC1 VM SettingsDC1 CheckpointDC1 Start ErrorError when entering DC1.vhdx in Virtual Hard DiskI have Windows HyperV Server 2012R2 with a virtual machine "DC1". This morning, during windows server backup, the building lost power.
When electricity was returned, DC1 VM failed to start stating that it was missing DC1_69E13A45-C913-43CA-887F-1D3481F975B8.avhdx file. But I could not find that avhdx anywhere on the hard drive. Since DC1.vhdx does exist, I tried to replace DC1_69E13A45-C913-43CA-887F-1D3481F975B8.avhdx with DC1.vhdx, but it fails.

Can I just click "Remove" button in the DC1 VM Settings screen?
Hi, i'm looking for a way to backup my virtual machines inside an ESXi 6.7 server to another ESXi server.  

I know I can Veeam or convert them over, but I was wanting to have it automaticaly run at night, like just the changed files, or even to a backup file on another server.  I wanted it to go to the same media so I don't end up with multiple of the same thing.

Thanks all.
I wanted to give a "least privilege rights" to a backup user on my Vmware center.
That username will be entered in my newly installed Veeam server.
So I created a user name _bkpsrv and give it AD group "Backup Operator"
Then I went on my esx, right click on it , select ADD PERMISSION
I selected "Backup Operators" and selected "VMware Consolidated Backup user" and pressed OK.

Veeam still don't accept to connect using it AND WORSE, now when I right click on my esxi, most options are grayout!

I have a server that I want to take out of commission.  I have 3 VM's I want to keep on the same storage, which is shared but I want to move those two hosts to another server.  I tried to migrate it however, even with vmotion enabled it will not migrate because it doesn't see the other hosts.  Is there any other way to move these boxes without  have to shut them and deploy OVF?

hi there is no internet in my vm but my host got internat
I need to secure a couple websites, and am looking for the ideal SSL solution to handle multiple domain names / multiple hosts. Here is a breakdown of my topology.

Website 1 - Self hosted IIS server. This server has multiple IP addresses (3 different ISP connections) and host names, but all point to the same exact virtual machine, aside from a replica that is stored at a remote location, but would need to be able to come online as a failover. - points to (onsite IIS Server) - points to (onsite IIS Server)  - points to (onsite IIS Server) - points to (offsite backup of IIS server)

Website 2 (Wordpress) - GoDaddy VPS hosted, with Name Cheap backup website - points to when there is a fail over, I auto redirect the DNS for to go to NameCheap Hosting

I was thinking about purchasing a single SAN SSL that includes every domain. However, I am not sure I will be able to install that SSL on the IIS server, as well as the go-daddy and name-cheap hosting.

Looking for advise.

Thanks in advance!!
I have a 32-bit computer (OS) that is running on a Windows Server 2012 R2 Hyper-v host. I would like to upgrade to 64-bit. I figure this was a p2v move by my predecessor. Can I do an in place upgrade? How do I figure out how the processor is configured or would it be 64-bit because the Host is?

I am having a problem downloading a trial version of VSAT.  My overall objective is to complete a comprehensive analysis (datastores, networking, host, VM Tools, Updates and VM performance within a VMware 6x infrastructure.  I don't believe VSAT will give me all the answers I am looking for.  Is there a comprehensive set of tool(s) that can assist in reaching my objective.

We need to Migrate Windows 2000 Server on vSphere 6.5

Existing Windows 2000 is a Physical Server , How can we migrate this to VM using VM converter supported version for 6.5?

What should be best approach to get it migrated to VM on my vSphere 6.5

I am administering NetBox v2.5. Browse the following link to get a basic introduction to NetBox if you are not familiar.  I need to sync VMware 6x with NetBox for the purpose of capturing vCenter inventory of all VMs across all clusters and datacenters.  Scripting is an option, but I prefer to avoid scripting the task. Based on my research, I believe there is a module within NetBox to achieve this objective.  Is there a way to configure NetBox without scripting the task.

Thank you.


can I migration a VM of linux from Hyper-V to VMware?
Does anyone have some advice in regards to best practice for installing Windows Admin Center in client's SMB Server 2016/19 environments and remotely access for our small team of techs.

Typical scenario:
1 x Physical Server running Hyper-V Host.  With 1 x Server 2019 VM with AD for standard file/printer shares. 10 - 15 users.

I'm thinking installing it on the Hyper-V host in Gateway mode, but it seems a bit of an overkill.  Also not best from licensing perspective to install anything on the host as it then should be licensed as another Server OS?

I have 2 of Dell Server PowerEdge R 510.
Both have got Windows 2019 Server as the OS right now.
I have a SAN (Storage Area Network) which is Dell PowerVault MD 3200 (12@ SAS 600GB).
I installed the “MDSM” (management software Dell Modular Disk Storage Manager at each of R 510); accordingly, from both of the R 510, I can see the MD 3200.

The Goal: I want to create some virtual machines at both R 510 which get the storage from MD 3200.

Note: I do have a little knowledge of Dell Server and no experience in VM machines; I have recently worked with Dell servers; This forum has helped me a lot; something like, it is big challenges in installing Win Server 2019 at R 510 which is INSTALLED now at both R 510, ETC.

Question: How to configure the SAN so it can be linked to VM machines at R 510?

hi how can i set java home in linux
i did this in my /etc/profile

Users in a "multi-tenant" environment can see each other. I am trying to figure out how to limit that. My predecessor set this up and it became a problem because they were sharing the same NAS for backups. One company got a CryptoLocker that infected everyone's backups and took down multiple companies. My company provides hosting for 5 different companies to access network shares. The way the network is setup is that I have a Domain called There are 5 different Servers that are part of this Domain. They are all running HyperV. They are all on the IP Scheme 10.16.1.x. On each of the HyperV Servers is a different company's Virtual Servers. Each company has their own IP scheme of 10.16.2.x or 3.x or 5.x etc. They all share the same Firewall/Gateway of 10.16.0.X. When they log in to their network, they only get their shares and can only see their servers. HOWEVER, if you do a simple network scan or search the network, you will see the other Servers. I want to keep them from seeing the other servers but still allow them to use the same Firewall. How can I accomplish this?
Hello Experts,

Hope are busy with resolving issues. So, I had bought Server 2016 Standard License (That allows us 2 VMs or One Physical server). I used that licensed to installed only one VM on Winodws Hypervisor.

1) Its little bit stupid question but still I have to ask, Is there any way to use that license to install another VMs but on another physical machine?

2) If I will move this VM (Winodws hyper visor) to VM ware, Is  am allowed to use same winodws server license (Licesne mobility)?
I have 3 server running with Proxmox 6.0.4 and when we clone a vm, it happens from time to time that the IO just goes 100% and stays there.
We shut down all vm's and even there, the IO is 100%.
I runs on 2 240gb SSD in raid 0.
The only way to fix that is by rebooting.
We tried disable the CACHE on the controllers = same thing.
What would cause that and what would fix that?
I want to build a backup server, windows 2019, that wont be on the domain and will have Veeam and pickup my VMware infrastructure: do a windows 2019 essential licence on it will do? It is half price and I guess it would.
I am running a VM on Microsoft Azure (Windows).
It has one external IP (Public) and 3 Private IPs.  When I open IIS I can bind one website to one of the private IPs, so far so good.
But then when I bind a different website to one of the other private IPs I created the website cannot be reached anymore. If I change it back to  *  then the website comes up.

What am I missing in the configuration?  I need to bind it to one of the additional private IPs I added because I need to use an SSL on that site, without that I get SSL errors.
I have an ESXi server running a VM of Windows XP. I need to be able to print from DOS in specific from DBASE and Wordperfect. I have this running in Virtual PC (XP Mode) at the moment and it works fine. From what I remember to get this working in Virtual PC i installed the printer dirver in windows then enabled printer pooling and then just selected LPT1 as the second destination in the windows printer driver. This seems to work fine in Virtual PC but not in ESXi. It is completely possible I'm not duplicating what I did in the past but I cant seem to figure it out.

Im just trying to move this VM to a server vs having it on a workstation.

Your Help is very appreciated,

we’ve just did an upgrade to win10, ofk2016.
however, we have some apps to run best on win7/ofc2010.
was wondering if there is a way to run a virtual instance of  Win7 w/ ofc2010??

or image a current system with win7 w/ ofc2010 and run that virtually on my Windows 10 system??

thank you
vCenter Version: vSphere Client version
ESXi Version: 6.5 10719125

Need to move ESXi hosts(Haswell CPU Generation) from Cluster 1 to Cluster 2 (EVC Enabled Cluster)
Need to know if this approach will work with no down time:

Cluster 1 (EVC Disabled)

Cluster 2 (EVC Enabled - Haswell CPU Level) (Currently No ESXI Hosts Exist in Cluster!!)

Each ESXi Host is at the same CPU level as Cluster 2 (EVC Enabled - Haswell CPU Level)
I cannot simply move the esxi hosts because there are not enough resources in Cluster 1 to compensate VM's if even one ESXi hosts were to enter maintenance mode.

So instead i will

1.) disconnect each ESXi host in Cluster 1 from VC and remove one by one
2.) Add each host to New EVC Enabled Cluster 2

Will this work without down time??
