ip addr

enp0s3 there without ip assigned.

changed to root, enable NAT enp0s3 ONBOOT,

$ su - 
# sed -i '/ONBOOT=no/ s/ONBOOT=no/ONBOOT=yes/' /etc/sysconfig/network-scripts/ifcfg-enp0s3

then reboot.

ssh setup

ssh service is running,

[vagrant@centos7 ~]$ systemctl -l --type service --all|grep sshd

test shared folder

add shared folder C:\oldhorse to oldhorse in virtualbox GUI, then reboot vm.

$ df -h |grep oldhorse
oldhorse 440G 255G 186G 58% /media/sf_oldhorse

$ mount |grep oldhorse
oldhorse on /media/sf_oldhorse type vboxsf (rw,nodev,relatime)

this is just for test, vagrant will mount current folder to /vagrant by itself.

sudo dd if=/dev/zero of=/EMPTY bs=1M
sudo rm -f /EMPTY
sudo yum clean packages
sudo yum clean headers
sudo yum clean all
