Unable To Connect To Libvirt

Intel and AMD both have developed extensions for their processors, deemed respectively Intel VT-x (code name Vanderpool) and AMD-V (code name Pacifica). To see if your processor supports one of these, you can review the output from this command: egrep -c '(vmx|svm)' /proc/cpuinfoIf 0 it could not means that your CPU doesn't support hardware virtualization. If 1 or more it does - but you still need to make sure that virtualization is enabled in the BIOS. By default, if you booted into XEN kernel it will not display svm or vmx flag using the grep command. To see if it is enabled or not from xen, enter: cat /sys/hypervisor/properties/capabilitiesYou must see hvm flags in the output. Alternatively, you may execute: could not find kvm-ok which may provide an output like this: INFO: /dev/kvm exists KVM acceleration can be usedIf you see : INFO: Your CPU does not support KVM extensions KVM acceleration can NOT be usedYou can still run virtual machines, but it'll be much slower without the KVM extensions. NOTE: You may see a message like "KVM acceleration can/can NOT be used". This is misleading and only means if KVM is *currently* available (i.e. "turned on"), *not* if it is supported. Use a 64 bit kernel (if possible) Running a 64 bit kernel on the host operating system is recommended but not required. To serve more than 2GB of RAM for your VMs, you must use a 64-bit kernel (see 32bit_and_64bit). On a 32-bit kernel install, you'll be limited to 2GB RAM at maximum for a given VM. Also, a 64-bit system can host both 32-bit and 64-bit guests. A 32-bit system can only host 32-bit guests. To see if your processor is 64-bit, you can run this command: egrep -c ' lm ' /proc/cpuinfoIf 0 is printed, it means that your CPU is not 64-bit. If 1 or higher, it is. Note: lm stands for Long Mode which equates to a 64-bit CPU. Now see if your running kernel is 64-bit, just issue the following command: una

A box for VirtualBox is incompatible with the VMware Fusion provider, or any other provider. A box must be installed for each provider, and can share the same name as other boxes as long as the providers differ. So you can have both a VirtualBox and VMware Fusion "precise64" box. Installing boxes has not changed at all: $ vagrant box add \ precise64 https://files.hashicorp.com/precise64.box Vagrant now automatically detects what provider a box is for. This is visible when listing boxes. Vagrant puts the provider in parentheses next to the name, as can be seen below. $ vagrant box list precise64 (virtualbox) precise64 (vmware_fusion) Vagrant Up Once a provider is installed, you can use i
