VM image for CentOS• Version 6.6• 64 bits• ftp://

ftp.cuhk.edu.hk/pub/Linux/centos/6/isos/x86_64/CentOS-6.6-x86_64-bin-DVD1.iso

• 32 bits• ftp://

ftp.cuhk.edu.hk/pub/Linux/centos/6/isos/i386/CentOS-6.6-i386-bin-DVD1.iso

• If you are not sure, just use the 32 bits• Create a New Virtual Machine > Installer disc image (iso)• Follow the wizard and wait for OS setup
