I updated the awk script also so that it now outputs in csv format instead of ssv...so give it a try.
Code:
awk -F, '{
   v = $2
   gsub(/[aA-zZ ]/, "", v)
   if (!x[$1])
      x[$1] = $1
   n = split(x[$1], a, " ")
   a[v+2] = $NF+0
   x[$1] = ""
   v = (v < n ? n : v+2)
   for (i=1; i<=v; i++)
      x[$1] = sprintf("%s%s%s", x[$1] ? x[$1] : "", a[i] ? a[i] : 0, i < v ? " " : "")
} END {
   for (i in x) {
      gsub(" ", ",", x[i])
      sub(",", " ", x[i])
      print x[i]
   }
}' file

processcsv.py

PROCESSCSV.PY(1)					      Virtualization Support						  PROCESSCSV.PY(1)

NAME

       processcsv.py - process virt-top CSV files

SUMMARY

	virt-top --csv data.csv
	processcsv.py < data.csv

DESCRIPTION

       virt-top is a top(1)-like utility for showing stats of virtualized domains.

       processcsv.py is a simple Python script that post-processes the output of "virt-top --csv".

       It is used like this:

	virt-top --csv data.csv
	processcsv.py < data.csv

       The second command will overwrite the following files in the current directory:

       "global.csv"
	   This contains the global (host) statistics columns from the CSV file.

       "domainNN.csv" (multiple files)
	   For each libvirt domain ID NN, a file is created containing the per-domain statistics from the CSV file.
