RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

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?
