4.5.2 Populating the Root File System
The root file system for the guest may be populated in a number of ways:

Copying the root file system of dom0
■
Installing an operating system
1.
To copy the root file system of dom0, mount the guest root partition to /mnt:
# mount -t <File system type> <Guest Root Partition> /mnt
Copy the root file system from dom0 to domU:
# rsync -avH /boot /mnt
# rsync -avH /root /mnt
# rsync -avH /dev /mnt
# rsync -avH /var /mnt
# rsync -avH /etc /mnt
# rsync -avH /usr /mnt
# rsync -avH /bin /mnt
# rsync -avH /sbin /mnt
# rsync -avH /lib /mnt
If your computer is a 64 bit computer, enter
# rsync -avH /lib64 /mnt
Then continue for all computers:
# rsync -avH /selinux /mnt
# mkdir /mnt/{proc,sys,home,tmp}
# chmod 777 /mnt/tmp
# unmount /mnt
