Genymotion emulator won't start. Stays still forever in the "android" black bg screen

Question

It's a fresh install, first time trying to use it, and it just doesn't work. This is all i get to see, with the CPU fan spinning fast all the time:

I wanted to see that little black monitor preview big to read the letters, it's all like this:

These are some of the errors I can see in the logs:

In Google Galaxy Nexus - 4.3 - API 18 - 720x1280-genymotion-player.log I have some of these as well:

I've uploaded here at pastebin the results of searching the word "error" in all log files generated by genymotion (456 hits in 16 files).

Everybody on the internet praises this emulator so much that i don't want to give up so fast, but I certainly don't know how to fix it. I've googled these different errors, nothing of use.

Answer 1

I had the same issue and I tried many things for days then I noticed this answer. It was mentioned that they had a network problem and I remembered in my general-genymotion.log file I saw this line:

[Genymotion] [Error] Output command: "VBoxManage: error: DHCP server does not exist" My problem was solved after I removed DHCP's from my network also I cleared all catches from genymotion

Also used my local ADB instead of genymotion's default:

Genymotion->Settings->ADB->Use custome Android SDK tools

After that:

Genymotion->Settings->Misc->Clear cache
