Created attachment 813516 [details] Descrition of cross-vm feature and testing ideas A new feature was recently added to the systemtap master branch which will allow users to perform cross-vm instrumentation using a virtio-serial channel. (Related commits 59bbd46 to 765a5d6). It would be great if we could rebase to include this feature. I've attached a document providing more details on the feature and how it could be tested. Thanks, Jonathan
As a test, I successfully ran check.exp with all the examples modified to run on my virtual machine. I used the following one-liner (from the testsuite/systemtap.examples directory): find . -iname '*.meta' | xargs -n 1 sed -i '/^test_installcheck: stap/ s/$/ --remote libvirt:TestVM/' Hope this helps!
The last_100_frees example seems to be failing because of: WARNING: cannot find module /usr/lib64/libc-2.17.so debuginfo: No DWARF information found [man warning::debuginfo] semantic error: while resolving probe point: identifier 'process' at last_100_frees.stp:5:7 source: probe process("/lib*/libc.so.*").function("free") [...] IOW glibc-debuginfo not installed. The testsuite does not rpm-prereq it, but this test case needs it.
