Hi , all : There is a problem on executing awk command to remote servers; The shell test script is like this : 1. #!/bin/sh 2. 3. _CMD="ssh root at localhost" 4. 5. cpu_num="$($_CMD awk '/processor/{count["proc"]++}; END{print count["proc"]}' /proc/cpuinfo)? 6. 7. echo $cpu_num My root account can entry the server without the passwd. But I found no result on the screen . Is there some error on that script ? By the way , I...

Hi All, The following patch set provides a low-overhead system for collecting kernel tracing data of guests by a host in a virtualization environment. A guest OS generally shares some devices with other guests or a host, so reasons of any problems occurring in a guest may be from other guests or a host. Then, to collect some tracing data of a number of guests and a host is needed when some
