cat <(cut -d: -f1 virtual.txt | head -n 11) <(sed 's/.*: //' virtual.txt) | xargs -d '\n' -n 11 | column -t

Explanation

1. cat <(command 1) <(command 2) - <() construction makes command output appearing like a temporary file. Therefore, cat concatenates two files and pipes it further.

   • command 1: cut -d: -f1 virtual.txt | head -n 11, gives us the future column headers. cut separates virtual.txt to two columns and print only first column. The head command takes this column and output first eleven lines from it.
   • command 2: sed 's/.*: //' virtual.txt - gives us the future column values. sed removes all unneeded text and leaves only values.

2. xargs -d '\n' -n 11 - each input item is terminated by newline. This command gets items and prints them by 11 per line.

3. column -t - is needed for pretty-printing displays. It displays our lines in a table form. Otherwise, each line will be different width.
