i try start vagrant box on windows 8.1 (64 bit) system doesn't work. i'm using setup on 2 mashines without problems.

this get:

$ vagrant bringing machine 'default' 'virtualbox' provider... ==> default: importing base box 'puphpet/ubuntu1404-x64'... ==> default: matching mac address nat networking... ==> default: checking if box 'puphpet/ubuntu1404-x64' date... ==> default: setting name of vm: vagrant-lamp_default_1411285570202_20465 ==> default: clearing set network interfaces... ==> default: preparing network interfaces based on configuration...     default: adapter 1: nat     default: adapter 2: hostonly ==> default: forwarding ports...     default: 80 => 8080 (adapter 1)     default: 22 => 2222 (adapter 1) ==> default: running 'pre-boot' vm customizations... ==> default: booting vm... ==> default: waiting machine boot. may take few minutes...     default: ssh address: 127.0.0.1:2222     default: ssh username: vagrant     default: ssh auth method: private key     default: warning: connection timeout. retrying...     default: warning: connection timeout. retrying...     default: warning: connection timeout. retrying...     default: warning: connection timeout. retrying...     default: warning: connection timeout. retrying...     default: warning: connection timeout. retrying...     default: warning: connection timeout. retrying...     default: warning: connection timeout. retrying...     default: warning: connection timeout. retrying...     default: warning: connection timeout. retrying...     default: warning: connection timeout. retrying...     default: warning: connection timeout. retrying...     default: warning: connection timeout. retrying...     default: warning: connection timeout. retrying...     default: warning: connection timeout. retrying... 

i looked solutions nothing helped. i've virtualization enabled , tried run mashine in gui mode, no way... idea? more information needed? please ask, don't know should provide.

i solved problem disabling hyper-v since virtual box cannot run hyper-v enabled. have decide want use.

disabling hyper-v: search "windows features". there can uncheck hyper-v. after have restart machine.

i rather suggest use vagrant box provides hyper-v.
