I was getting same errors after an install on Windows 10. And I tried restarting but it did not work, so I did the following (do not recommend if you have been working in docker for awhile, this was on a fresh install):
1) Find the whale in your system tray, and right click
2) Go to settings > Reset
3) Reset to factory defaults
I was then able to follow the starting docker tutorial on the website with Windows 10, and now it works like a charm.
Error Code:
Solutions:
1) For Windows 7 Command Window(cmd.exe), open cmd.exe with run as administrator and execute following command:
You will receive following output:
Copy the command below and execute on cmd:
And then execute following command to control:
2) For Windows 7 Powershell, open powershell.exe with run as administrator and execute following command:
And then execute following command to control:
3) If you reopen cmd or powershell, you should repeat the related steps again.
For me the issue was virtualization was not enabled.
On windows 10: Go to task manager -> Performance -> CPU and you should see as section as "Virtualization : Enabled"
If you do not see this option, it means that virtualization has not been enabled.
Another interesting thing to note is you must have Hyper V enabled. However as I was using parallels desktop, I had to enabled to "Nested Virtualization" for Hyper V to be "truly enabled". So if your windows is a VM, check out the settings for Parallels (or whatever you're using) that nested virtualization is enabled.
I had the same error on Windows. Turns out I was missing the Container feature.
Restart server
When up and running ensure the Docker service is running
You can start Kitematic when you get this error. It will display a button to reset the VM and will fix the issue.
