I have three VMs.
"C:\Program Files\Oracle\VirtualBox\VBoxManage.exe" list vms
"Win7 Ultimate 32-bit" {baeda25c-9f47-4c4f-92f9-a93a747fbfa7}
"Win8.1 Pro 64-bit" {daef4bdd-22a1-4ebd-a19a-6d9701e8e767}
"Win2Go LTSB 32-bit" {bf116454-4c13-4bd0-9aa9-3ee7d29b2d63}
All three can be launched via
VBoxManage startvm "the vm name" I.e
Waiting for VM "Win7 Ultimate 32-bit" to power on...
VM "Win7 Ultimate 32-bit" has been successfully started.
Waiting for VM "Win8.1 Pro 64-bit" to power on...
VM "Win8.1 Pro 64-bit" has been successfully started.
Waiting for VM "Win2Go LTSB 32-bit" to power on...
VM "Win2Go LTSB 32-bit" has been successfully started.
The Win7 VM Only works if virtualbox.exe is running before launching it via a cmd. Otherwise you get the following error:
VBoxManage.exe: error: Could not find a registered machine named 'Win7 Ultimate 32-bit'
VBoxManage.exe: error: Details: code VBOX_E_OBJECT_NOT_FOUND (0x80bb0001), component VirtualBoxWrap, interface IVirtualBox, callee IUnknown
VBoxManage.exe: error: Context: "FindMachine(Bstr(pszVM).raw(), machine.asOutPar
am())" at line 722 of file VBoxManageMisc.cpp`
The others don't cause an error if the VBox GUI(virtualbox.exe) is not running. I have no idea why. Anyone?

Using ESXi 6.7 as the main VM host. Created a VM with the necessary hard disk, CPU and RAM requirements.
Network interface is configured as VMXNET3. However, when the installer gets to the network configuration step, it fails to get an IP address. If I choose the E1000, same result.
What do I need to do for the DHCP process to complete?
Other VM's on the same host are able to acquire IP address without any problems.

I am trying to connect to a Linux server for c++ development through Visual Studio for debugging purposes. The server is a computing cluster and works in the following way:
You have a ssh portal let's say login#website.com where I use my username and password to log in.
But then to actually run an application I need to do ssh gpu-server in the SSH terminal that I used to login. And then on this server I can run c++ applications that require the use of a gpu.
The problem I am facing with Visual Studio, is that I can set up the first server as a remote connection on the Connection Manager and it works perfectly. But I cannot Debug or compile anything on this server since it doesn't have a gpu (for my application I need a GPU). For this I need to do a second ssh. But I do not see how to do this with Visual Studio. I tried using a before build event on the configuration, but it just hanged when it does the command ssh gpu-server.
How could I do this "double" ssh on Visual Studio?
I cannot just connect directly to the second one since I am not an administrator on that cluster.
Thank you.
One way would be to setup a SSH tunnel so that visual studio can connect directly to your target machine.
For example if you are using Putty as your SSH client go to "Connection", "SSH", "Tunnels", set the "Source Port" to something like 8000 and the "Destination" to gpu-server:22 select the type as "Local". Once you have opened the ssh session visual studio should be able to connect directly to gpu-server via localhost:8000.

Here I am exploring the security features, and when I enter "firewall-cmd --panic-on" to the CLI, the system just hangs idle.
Centos 7
Kernel 3.10
I think this is not supposed to happen, b/c as I read the documentation, I see I should be able to firewall-cmd --panic-off, but I cannot even ssh through another terminal unless I restart the server.
Is the system corrupt?
Is there a bug with "firewall-cmd --panic-on"?
How can I figure out the source of the problem?
--panic-on
Enable panic mode. All incoming and outgoing packets are dropped, active connections will expire. Enable this only if there are
serious problems with your network environment. For example if the
machine is getting hacked in.
As this switch drops all incoming connections and kills established active connections, so you can not issue --panic-off using ssh. You have to run firewall-cmd --panic-off using console access. running firewall-cmd --panic-on will apply configuration in runtime level so by simply restarting the server you can access ssh session. never run firewall-cmd --panic-on --permanent you can verify panic status by running firewall-cmd --query-panic

I imported a VM from Oracle and tried to open it.
When I try to run the VM, i get the following message:
VT-x/AMD-V hardware acceleration is not available on your system. Your
64-bit guest will fail to detect a 64-bit CPU and will not be able to
boot.
As it can be seen from configuration, the VT-x is available on my machine:
Can someone tell me what else should I do in order to be able to start he VM, please?
Thank you,
You need to Enable Virtual Hardware in BIOS.
Press F2 key at startup BIOS Setup.
Switch to the Advanced Mode tab then choose CPU Configuration
option.
Scroll down to the "Intel Virtualization Technology" value, and then
change [Disabled]->[Enabled].
Save Changes and Exit.
It depends on what tool your using to run your VM,
e.g. Virtual box there is setting to enable Hardware virtualization for guest VM
Edited:
If you don't have hardware Virtualisation enable you can try with software Virtualisation this will impact performance
This is how I resolved this problem:
I restarted computer, disabled virtualization from BIOS, and started computer.
When I opened Virtualbox, nothing changed (the same error).
I restarted computer again, and enabled virtualization from BIOS, and started computer.
When I opened Virtualbox, guest OS started without problem.

I've bought a VPS, but it has been restarting on occasion. The server is meant to be running my game server 24/7, but when it restarts obviously the game goes down too.
I'm trying to setup a scheduled task to run the C++ game server EXE on start up, but it isn't working. I've already set a scheduled task to run WAMP so I know that the scheduled tasks actually work, but for the C++ EXE it just isn't.
I've even compiled a very simple program that just waits for user input before closing, and set this as a scheduled task. When I restart the server, this program doesn't even run.
Any ideas? Is this a problem specific to running an executable like this?
It's also strange, on the scheduled task manager it says the program is running, but no console is on screen...
