Cuckoo cant start virtual machines for analysis #397

Closed phant0m3 closed 7 years ago

phant0m3 commented 7 years ago

I followed the install tutorial and got cuckoo running perfectly and everything was fine, however after a reboot I cant seem to get cuckoo to start the analysis.

OS:Ubuntu 16.04 Hypervisor: Virtualbox

I checked that the vboxnet0 interface is up and running but i keep getting the following error. (As mentioned everything was working perfectly before a reboot, VM boots fine if I boot it from virtualbox, VM is installed under the same user as cuckoo is running)

Can you move '/home/cuckoo/.local/lib/python2.7/site-packages/gevent/' directory to temporary place to backup and execute cuckoo? seems gevent.subprocess used instead of subprocess module

Fixed / Solved

A quick update, first I moved gevent from /home/cuckoo/.local/lib/python2.7/site-packages/gevent/ to a backup location as suggested but still got the same error.

I then tried uninstalling gevent using pip but still got the same error.

What ended up working was moving gevent from /usr/local/lib/python2.7/dist-packages/gevent (not sure why removing it with pip did not remove this).

Cuckoo now works even after a reboot (will try and see if I can figure out how to reproduce the error and if any of my other apps need gevent)

Thanks for your help!
