We currently have a ESX Environment  which has 1x Physical vSphere Server, 1x SAN (Another coming soon) 2x ESXi Hosts.  We currently have licensing for vSphere and ESX Essentials.  I need to add 2 more ESX Hosts and I know in Essentials / Essentials Plus there is a Max limit of 3 physical hosts.  I need to find out which version would be able to allow me to run vSphere server with 4x ESX Hosts. I have tried to find out for Standard Edition but a straight forward answer to this has alluded me and my Google searches. Are any of you able to help on this matter?  Thanks,

This is a  about Licensing.    Questions on licensing are off-topic on Server Fault.  If your question has been closed as a duplicate of this question, then this is because we want to help you understand why licence questions are off topic rather than just telling you "it just is". In all likelihood, this question will not address your question directly, it was not meant to.    I have a question regarding software licensing. Can the Server Fault community please help with the following:   How many licenses do I need? Is this licensing configuration valid? What CALs do I need to be properly licensed? Can I run this product in a virtual environment? Can I downgrade this product to an earlier version? Am I entitled to feature X with license Y?

I'm having difficulties configuring  in VMware Workstation 12 hosted on Windows 10 serving two Linux guests.  For instance, this is what I'm trying to configure in VMware Workstation:     VM 1 – transmitting recorded traffic on a designated private network VM 2 – receiving the incoming traffic from VM 1, connected to the same private network   Assuming both Linux guests are configured properly for Promiscuous Mode, how should I configure the network in VMware Workstation to support that?    While it's pretty straight-forward to configure Promiscuous Mode on ESXi, I couldn't find the matching setting in VMware Workstation.   - ESXi screenshot for instance

Apple now allows you to run OS X inside a Virtual Machine as long as the host is running Apple hardware. Because we need to test our web site on various versions of Safari, we picked up a Mac Mini running Yosemite for testing purposes. The idea is to run Mavericks (currently our largest user base) and possible Mountain Lion in a VM on demand, similar to what .  However, I've yet to be able to find a place to download prior installer apps. I've found other StackExchange posts referring to the App Store, but since this is a new Apple ID there are no previous purchases for old versions, and as far as I can tell they are no longer available to "purchase". Likewise, I have not been able to find any OS X Installer apps on the Apple Developer site.  Am I missing something? Is there an easy-ish way to get these apps to install OS X to a VM?  (For VM host, we are currently using Virtualbox, but would be willing to use VMWare or Parallels if needed)

I was looking for a lightweight X server, but failed to find one. Then I found out about Wayland. I says that it aims to coexist with X, but can run standalone.  When I try to compile it, it needs Mesa, which needs X.  What exactly is Wayland?

Is /etc/resolv.conf useless in  (Precise Pangolin)?  I see that the DNS server information is stored in  now. The nmcli command line tool can list that for you.  If I want to add one more  server, will adding it to /etc/resolv.conf by using the resolvconf package help?

I'm using VM Ware (specifically the player) and i'd like to attach a multiple mouses and have one for each VM (same idea with keyboard but i havent tried keyboards yet). I'd like several people using their own vm. I cant seem to figure out how to lock the mouse into the VM. If i plug in a mouse windows uses both of them and i need to click onto an instance of vmware to get the mouse working there.  I tried clicking the USB area at the bottom of the player window and i got the error message     Cannot connect "BRAND USB Optical Mouse" to this virtual machine. The host requires this device for input.   Is it possible to dedicate a mouse/keyboard to a VM instance? I'm willing to use another VM software (but preferably free)

I have an Intel E7300 Core2 Duo processor with 2.66GHz speed. I need to run a 64-bit WinXP SP2 VMWare image. My host operating system is Win 7. So I just installed the VMPlayer from www.vmware.com.  The problem is when I run the VM image it says This host doesn't support VT.  If I continue I see Windows shows an error message saying     Attempting to load an x64 operating system, however this CPU is not compatible with x64 mode.   My question is how do I run this VM without buying a new processor? Any other tools or software?

This may be a bit of a noobish question, but I was taking a look at /etc/hosts on my new Xubuntu install and saw this:  127.0.0.1 localhost 127.0.1.1 myhostname   On most 'nixes I've used, the second line is omitted, and if I want to add my hostname to the hosts file, I'd just do this:  127.0.0.1 localhost myhostname   Is there a difference between these two files in any practical sense?

My host is x64 bits Windows 8.1.  I downloaded the latest Virtual Box (4.3) and I'm trying to create a VM with a 64 bits Ubuntu OS (ubuntu-12.04.3-desktop-amd64).  When I go to New VM wizard, it doesn't give me option to select "Ubuntu (x64)" as I have seen in other people's screenshots, only just "Ubuntu". As a result, the ISO can't boot. I tried in another PC and Virtual Box gives the x64 variants to most listed OS...  Control Panel shows x64 OS, x64 processor. My host laptop is a Sony Vaio VPCZ22UGX/N, Intel® Core™ i7-2640M processor. CPUz shows Vx-t is available on my processor, of course.  Here is what I tried so far:   I enabled IO APIC as required in the docs. I have virtualization enabled in the BIOS. It works fine in VMware. Check that Hyper-V is not running or even installed on my Windows. Same for VMware. I also tried running the command:  VBoxManage modifyvm [vmname] --longmode on    for that VM, but no change.. I think the issue is really that I can't select x64 variant of the Ubuntu OS for that VM. Other people seem to indicate that's a requirement, but I don't get that option for some reason.  I spent a lot of time and can't find what's wrong... Anyone knows what could be missing here?  Thank you very much!!  Eduardo

An interesting question.  I have logged into a Linux (most likely SuSE) host.  Is there some way that I can tell programmatically that I am a VM host or not?    Also assume that the vmtools are not installed.

We have a deployment with what I would call an Enterprise Cloud Provider. It's VMWare Infrastructure 3.5.x and includes VMotion / VMWare HA instances, etc.  At Provider 1 VMWare Tools was installed:   vmware-guestd is running and; at least two kernel modules are loaded, vmmemctl &amp; vmhgfs   Provider 1 does nightly VM Snapshots.  We are beginning a new deployment at Provider 2 (also an Enterprise Cloud Provider). They did not install VMWare Tools. Provider 2 does not do nightly VM Snapshots but rather file-system backups (using an agent).  From my reading it seems like at the very least VMWare Tools should be installed for the Memory Balloon Driver (vmmemctl) and from reading sources like  it suggests that certain VirtualCenter management operations also depend upon VMWare Tools being installed in the Linux guest.  Note that all of our instances are headless (default runlevel is 3) and RHEL.  It is hard to find authoritative information on this question and the aforementioned source is somewhat dated.  Can someone shed some light on this? What are the factors/criteria that would lead to an answer in the affirmative or negative?  TIA  Cheers

How can I create a virtual interface, that connects to the same network as the physical interface? I tried searching around but all I found is loopback. I need the other end of the wire recognizes this as two interface, so loopback won't do it. Hypervisors like VMWare have an option to do exactly this (VM and host are recognized as two devices on router's arp table), but in my situation using a VM is pretty much overkill. I just want another connection, or maybe some apps that can behave as a "virtual switch".  I'm on Windows, and it should be like this.     Seems like I'm not the only one having this problem. Someone  and  have also asked but there's no acceptable answer. My apologize, but it is extremely hard to search for this problem.

I'm running  on a Windows 7 (RTM) 64-bit host. When I create a new virtual machine and try to install 64-bit Windows 7 on that VM, I get "this CPU is not compatible with 64-bit mode."  Is there a way to create 64-bit virtual machines?

Is it possible, from within a windows 2008 virtual private server, to tell if the image is hosted in Hyper-V or some other virtualization technology? For example, are there any guest-os extensions that might be installed?  Background: I previously bought a VPS server from a company who offer VPS images hosted on either Virtuozzo or Hyper-V. I thought my original server was on Hyper-V, but it turned out I bought the wrong package. Now that the month is over I've ordered another server, and want to check I haven't made the same mistake.
