Description Frank Ch. Eigler 2010-10-07 12:27:19 UTC 
Please include key parts of systemtap-runtime in the RHEV-H image, to
permit remotely invoked systemtap probing.  As of systemtap-1.3, these
parts would be:

/usr/bin/staprun
/usr/bin/stapio

By RHEL6.1, systemtap-1.4 should be available, and may include an 
additional small binary to help smoothen the remote probing task.
Comment 1 Frank Ch. Eigler 2010-10-07 12:28:54 UTC 
Bug #634995 covers the future stap-1.4 rebase.
Comment 4 Frank Ch. Eigler 2010-10-07 14:31:26 UTC 
The way this would work with current-day code is that a development/management
machine, with all the debuginfo / compilers goo installed, would have a stap
user run 

   stap -p4 FOO.stp
   scp FOOBAR.ko root@rhev-host:FOOBAR.ko
   ssh root@rhev-host staprun FOOBAR.ko

basically according to the 'cross-compilation' pattern of operation.  There
is currently no man page that spells out this sequence, but is outlined on
our wiki:

http://sourceware.org/systemtap/wiki/TipCrossCompiling

With systemtap 1.4, these steps will be automated (with a proper man page
blurb).

Patch

Note:  bug asks for /usr/bin/stapio, but rpm adds /usr/libexec/systemtap/stapio instead

Testing:  
rpm -qa systemtap-runtime
ls /usr/bin/staprun
ls /usr/libexec/systemtap/stapio

rhevh 6.1-8

[root@intel-x5550-12-2 ~]# rpm -ql systemtap-runtime | grep staprun
/usr/bin/staprun
/usr/share/man/man8/staprun.8.gz
[root@intel-x5550-12-2 ~]# rpm -ql  systemtap-runtime | grep stapio
/usr/libexec/systemtap/stapio
[root@intel-x5550-12-2 ~]#
Comment 9 Mark Huth 2011-04-20 22:39:00 UTC 
Is it possible to get systemtap in the RHEVH 5.x as well?
