You can use a for loop and process substitution and some descriptor magic:
Code:
#!/bin/bash
for server in server1 server2
do
  ssh -x "$server" '
    echo "hello I am on `hostname`"
    sudo yum update infolist
  ' 2> >(sed "s/^/$server: /" >&3)
done 3>stderr

The stderr output goes to the file stderr, filtered by sed.
The sed prepends $server: to every stderr line. It can also prepend it once:
Code:
for server in server1 server2
do
  ssh -x "$server" '
    echo "hello I am on `hostname`"
    sudo yum update infolist
  ' 2> >(sed "1i\\
$server:" >&3)
done 3>stderr
