To install OpenVZ from a USB storage drive, you will need a 2 GB or higher-capacity USB drive and the OpenVZ distribution ISO image.
Make a bootable USB drive by transferring the distribution image to it with dd
.
Note
Important! Be careful to specify the correct drive to transfer the image to.
For example, on Linux:
# dd if=openvz-iso-7.0.0-3469.iso of=/dev/sdb
And on Windows (with dd for Windows):
C:\>dd if=openvz-iso-7.0.0-3469.iso of=\\?\Device\Harddisk1\Partition0
