Install VirtualBox in CentOS 7

Install VirtualBox in CentOS 7

Yesterday I installed VirtualBox for centos6.5, but it didn't take a day. Today I am idle. Try centos7. As a result, PS younger brother is also a beginner of linux. Many of them just found a solution, but I don't know why.

Strange O (∩ _ ∩) O ha!

1. Install centos7, which is much simpler than the old version.

2. Configure the network connection. After installing centos, use ifconfig to check that there is no IP address. solution:

Cd/etc/sysconfig/network-scripts/

Vi ifcfg-eno16777736 # note, we usually see if1__eth0, what is specific, use ifconfig to see.

ONBOOT = yes # Set onboot to yes

Restart the NIC:/etc/init. d/network restart

2. Install virtualbox:

1> download the RHEL software library configuration file of VirtualBox:

7> Installation extension:

1. VBoxManageextpackinstallOracle_VM_VirtualBox_Extension_Pack-4.3.16-95972.vbox-extpack

This is a problem.

VBoxManage: error: Details: code NS_ERROR_FAILURE (0x80004005), component ExtPackFile, interface IExtPackFile, callee nsISupports
VBoxManage: error: Context: "Install (fReplace, NULL, ptrProgress. asOutParam ()" at line 1140 of file VBoxManageMisc. cpp

However, virtualbox already exists in the system, so you can ignore this problem and continue with the next step.

1. 8>/etc/init. d/vboxdrvsetup

Here an error occurs:

Building the VirtualBox Guest Additions kernel modules [FAILED]
Your system does not seem to be set up to build kernel modules.
Look at/var/log/vboxadd-install.log to find out what went wrong.
Once you have corrected it, you can run/etc/init. d/vboxadd setup to build them.
