Hi,
When trying to connect the HyperVisor from a binary having setuid bit set , then I got following error:
Unable to perform virConnectOpenReadOnly function error(internal error: libvirt.so is not safe to use from setuid programs)
My test software config is the following :
-rwsr-xr-x. 1 root root 3374956 Feb 4 13:45 test
As this test software needs S bit to be able to access O.S. metrics counters , how may I use it to retrieve KVM metrics counters ?
You should re-write your app so that it does not need to have the setuid be present for everything it does. Create a tiny self-contained executable for *only* accessing OS metrics counters, so that bit can run setuid, and the main bulk of your app can run unprivileged.
