Virtual box has a nice feature of running a remote desktop server. This allows one to connect to the virtual machine remotely. However, I cannot find how to make the connection to several desktops of the same machine.
I have several physical screens attached to the PC and, therefore, there are several desktops available in the virtual machine. Whenever I connect to this virtual machine via the remote desktop service of virtual box, it always connects to desktop 1. While using TeamViewer, for example, I can see all the desktops.
Question: Is there a possibility to remotely access all the desktops of the virtual machine? I could not find any information neither in the docs nor in the posts.
Use different Remote Desktop Server Ports in the vm's config.
Then you can connect to several instances.

I am working on a application which cloned virtual machines from a running machine on a specific event in poweredon state. The machines later communicate each other based on event and I have to fetch out (sniff) the network packets through netmon virtual machine which is routed between them but I can't do so directly, I have to reboot the guest on virtual machines manually and then I can access the network reports.
I also tried to rebootguest of vm using pyvmomi but the machine guest will take too much time to be in initial state after boot, I also do poll in loop to check virtual machine guest tool status and network status as well but nothing work, I got the empty network reports.
I did some research and found this is the right place to post this question, please let me know I am in wrong direction.
I want to create a simple VPN like with User application. I went though different VPN application software. I can see most of them uses a Miniport Virtual adapter for example: OpenVPN use Windows TAP driver. Another VPN software uses both miniport and a filter driver. Note : Filter driver sends and receives data from the real physical Miniport. Isn't?
Now I am beginner in driver development process. I have some doubts regrading that VPN drivers. If I want to create a simple VPN application in ะก++ on windows environment,
Why most of the VPN software uses a Virtual adapter and filter
driver (optional)?
Is it mandatory to create a Virtual miniport adapter for VPN
application?
Can i create a VPN application with only filter
driver? (reading / writing packets )
If I create a new virtual driver, should I undergo the HLK/HCK driver signing test for windows 10 and onward?
In general unless an operating system exposes APIs through inbuilt filter drivers you do need to create your own. You will further see 2 basic types of usage.
Virtual Miniport/Nic - A VPN connection creates a virtual interface that can then also be referenced in other decisions like the routing table
Inline - These just sit between your the protocol stack and the physical interface and based on its own logic encrypts and redirects them.
That said atleast on Windows you have a few ways to create a VPN app which is user mode based. The newest and most active development is in the UWP api space of Windows.networking.vpn <

I have a Windows Server 2012 with only one ethernet card, and a VMWare workstation 11 installed on this server box.
I need to run multiple VMWares on this server box and connect to these VMWares from other machines within the same network of the server box. Thus, I need to assign an individual IP address to each VMWare.
I tried to make the network setting in each VMWare be bridged, but I can't ping the VMWares from the host system (the server box).
Is there any missing configuration?
Do I need to have more than one ethernet card? Or can more than one VMWare take different IPs shared with the host?
I have a virtual machine created from an linux image (and powered on). I want to be able to access its console in VCenter, but right now I am getting this error:
"A secure connection to the host could not be established"
The console is a black screen with nothing on it and no interaction. This happens for any VM in VSphere. Bizarrely I can telnet in to the console port 902, but there doesn't even appear to be any attempt to connect to the console (checking tcp/ip traffic in Task Manager).
SSHing in is not possible because the reason I wanted console access to begin with was to run commands to set up an IP address for this machine.
Some facts: Opening an external console window does nothing (same error). I'm running Windows XP Professional (out of VirtualBox if it matters). My colleague on the exact same setup (same version of XP, same version of VCenter) can connect to the console just fine.
Does this problem happen when you connect directly to the ESX/ESXi ?
if not you have connection problem beetween esx and vcenter.
you can find here a list of common ports :

Turns out that when connecting to vcenter I needed to use https instead of http. Boy howdy, do I feel smart now.
I've been using VMWare for a while and am very happy with it, but I would like to compare it with VirtualBox. Apparently the disk images are compatible, and I have successfully booted my Fedora based VM created by VMWare in VirtualBox... but the network is completely unavailable. How do you port a virtual machine from VMWare to VirtualBox and keep all the capabilities intact?
have you tried going into the options in virtual box and changing the network adapter to the VB one? VB is a bit different in it's virtual adapters, you might have to create a new one attached to the nic and then specify that one as the primary nic.
Are you sure that network is completly unavailable? VirtualBox is known to have a problem with ICMP support so you won't be able to ping any host from the guest OS. I ran into the same problem yesterday and the network was actually working.
If the network is unavailable, you may want to check your VirtualBox configuration and make sure you have a network card configured. If you do, then the next stop would be the OS running in the virtual machine. An unfortunate fact of some operating systems is that they don't always appreciate hardware changes. If the OS is not auto-detecting the change to the network card, you may need to reconfigure it to support the new card.
Another possibility is that you were using a fixed IP address. VirtualBox uses a couple of schemes for networking that are a bit different than VMWare. You may need to change the IP inside the VM to match the expected subnet.
Outside the VM, you need to use either a bridged networking device or configure ports virtual ports through the NAT system if you want to gain access to your Virtual Machine.
