It's probably impossible with Windows Server 2012 as the (root?) host, but with current Windows 10 and the upcoming Windows Server 2016: https://msdn.microsoft.com/en-us/virtualization/hyperv_on_windows/user_guide/nesting I am not sure if you can nest it like Hyper-V -> KVM though. Btw, you can still run qemu / virtualbox without ...

You can use the information from the article below. Basically, you need to set firewall rules and remove the block on the port you want to use. I've tried this while testing symfony demo application and it works perfectly. http://markonphp.com/use-php-built-server/

No wonder this doesn't work! Create port forwarding on the Host Only Adapter? How? As soon as I select Host Only Adapter, the Port Forwarding button is disabled. The same with the ambiguous instructions to use localhost. Nothing works. And nothing appropriate shows up in netstat either. (Then again, considering the host OS is Windows, should I be ...

I'm mostly basing on that serverfault post but I'll try to answer myself. If I create the VM and store the data in a ext4 file system, would the btrfs checksumming on the host server detect data corruption on the VM? No. From what I gathered there's no way the host system could detect data corruption on the VM file system. If the previous answer ...

Try Killing all the VMware Processes and Starting up VMware again. If that does not work start a new VM to possibly fix the issue with one of the steps below. Try creating a new VM, and attach the disk from the corrupted VM to it as the primary disk. If the disk itself isn't corrupted, it should boot right up. Steps. 1.Shut down the virtual machine. ...

1) I would split up the different services onto more VMs, since they don't cost you anything if you licensed Windows properly (datacenter license for the host). AD on one, DNS/DHCP on another, Exchange on a third, file/print on a forth, and bitdefender on a fifth. 2) Switches are fine, you'd need to segregate traffic from different areas though, for ...

The VM should be joined as usual without any kind of problem. Just check your VM is in the same IP range as the domain controller (because sometimes VirtualBox configures the VM network as 'NAT'instead as 'bridge' which is what you need to be in the same IP range). Regards

So what is that minimal/safe version compatible with VM installations? In general, any version of Windows 10 will work in a VM as well as any other. where I can get it? Microsoft's online store, or practically any retail computer store.

I can find nothing from MS, but Virtualization blogs seem to agree -- Windows 2012 Standard, and Datacenter will allow hot-adding vCPUs. Source Source

Check if the SSH is allowed or not allowed in your firewall settings, if you use Linux with a GUI it might be like this: Click on system -> Administration -> security level and firewall Click on firewall option tab, enable it, apply and save. Here you can allow telnet and https as well. Thanks

The easiest way to put a virtual machine directly on a Wifi network... is to put it directly on a Wifi network! Get a USB Wifi adapter, and "connect" it to your virtual guest. Then your virtual guest can use the USB Wifi adapter directly and independently of the host OS.

The real address is fe80::1:1, or fe80::1:1%enp0s8 with the scope identifier. Prefix length (the /64) is only used when configuring the interface and is not part of the address. It is equivalent to the "subnet mask", and you don't give the subnet mask to ping either, do you?

This is working now though I'd like to figure out a way to bridge mDNS as well (possibly as separate question). This follows this guide. Set up tap device (in my case it was done by virsh). Don't assign it any host address Set the ip forwarding and arp proxy Add route for this one specific ip only OR run a separate DHCP server for tap and add route for ...

I use VMWare most often, and I just set the guest OS's network card to be bridged to the Host network. The Guest doesn't know or care about the hardware layer in this case; VMWare handles the networking. Based on a comment above, it's going to be similar in other VM products.

Using cloud services to bolster your CPU performance is possible but bloated. To render the videos you would need an extremely fast network connection to constantly upload and download each individual file to cloud get it rendered there and then download it. Cloud computing would be more useful if you where executing simple commands on a large amount of ...

5chdn's solution is too cumbersome. Instead of Alt, use Win+Alt in guest and you're done. For example, to use Rubymine's multiple caret mode, original shortcut is Alt+click, which becomes Win+Alt+click. Easy peasy.

For number-crunching programs (very CPU-bound), there should be almost zero performance hit for the VM. The instructions run directly on the CPU, which is the same for host and VM. Even for serious compilation tasks, the performance difference is hardly noticeable. We run CentOS VMs in VMware on Windows. Since you're running Linux on the host, you might ...

There is no one single good answer to this. It depends a lot on how you use a VM and on which programs. E.g. using VMWare (a type 2 hypervisor) and a purely CPU bound program yielded almost full CPU speed. If I used the same hypervisor an a program with a lot of system calls I would get a serious slowdown. And things alos change when you use a type 1 ...

I tried @Andreas's solution but running the command didnt seem to result in anything, and I wasn't able to start my vm still. In the end my solution was to run net start vmx86 in an administrator cmd prompt.

From the FreeBSD side, it will work if you make the filesystem issue TRIM (use https://www.freebsd.org/cgi/man.cgi?tunefs for UFS; ZFS does that by default) and mount the storage over a medium that can pass TRIM requests (eg iSCSI).

You can read why in the current version of the user manual for the startvm command: Starts a VM with detachable UI (technically it is a headless VM with user interface in a separate process). This is an experimental feature as it lacks certain functionality at the moment (e.g. 3D acceleration will not work). So, yes, this is still a new few features ...

All x86 chips should work with both VMware & VirtualBox, but you'll need AMD-V (AMD name for hardware virtualization) to run 64 bit guest OS (it's possible to run it on Bochs or qemu, but far slower). For simplicity sake, you can just search the CPU series on cpuboss since AMD own site isn't too easy to navigate.

There are two things that I can think of: Your inserted SATA controller (U2.vdi) is wrong and you need to insert the correct one. Your IDE Controller is empty (which is less likely than the first solution). EDIT: To resolve the first issue you have to follow these steps: right click on the U2.vdi and remove it by Remove Attachment. click on the ...

These kind of issues will be automatically fixed by installing the VMtools. Once it is installed, it will automatically show the available network adapters in network connections manager. After that try to ping loop back ip and assign a valid ip for your VM machine.

I have the same issue and haven't found an ideal solution yet. How about mapping some key combination to the media features? I use Super+F10 for mute, Super+F11 for volume down, etc. Then you could change the system setting in the OSX Host to use all Fn keys as normal Fn keys for a two button shortcut in Ubuntu Guest (Super+F10), or leave the Fn keys as ...

I don't have a OS X system to test this with (but it works on vbox on windows, and won't hurt to try) , but if you're primarily working in the VM, turning off autocapture should do the trick - least when I tried a shortcut on windows. Go to "Input" -> "Keyboard" -> keyboard settings, then unselect "Auto Capture Keyboard". You'll need to hit right ctrl to get ...

Using multiple IP addresses You can assign the host multiple IP addresses on the same network interface. Here are some tutorials: Connect to two LAN networks with a single card or How to Quickly Add Multiple IP Addresses to Windows Servers Next, you need to check that your host is reachable from the outside on all these addresses. You could use something ...

It' s possible: Windows 7 as a HOST with VirtualBox/VMware and you virtualize a other OS (Win7, Win10, GNU/Linux ...) will be the guest. Process: Install Virtualization software at Host. (VirtualBox with VirtualBox it´s very easy). Create Virtual Machine at Host. Install OS at Virtual Machine, will be the guest.

It is possible to run any kernel version inside the virtual machine, just as it is possible to run other operating systems or even emulate other processor architectures. The virtual machine software runs on the host kernel, and the the virtual hardware executes the guest system. There may be some features (such as seamless desktop integration) that only ...

It sounds as if you have no extra disk space. You would be able to do this using the VMware converter program, recreating the virtual machine in a different place: Growing, thinning, and shrinking virtual disks for VMware ESX and ESXi (1002019) Shrinking of a thin disk can be performed only by using VMware Converter in the virtual machine and ...

A virtual machine shares the physical network card with the other virtual machines on the physical machine. So if a DDoS attack is powerful enough the overwhelm the capacity of the network card it would indeed deny access to the other virtual machines. However this assumes that there is no quality of service software in place, which might only allow the ...
