good day to all. i still have not solved my problem with event handling. currently i have following code void libvirt_eventloop_thr_func() { while(true) //TODO: stop somehow on exit { if(virEventRunDefaultImpl() < 0) { virErrorPtr err = virGetLastError(); fprintf(stderr, "Failed to run event loop: %s\n", err && err->message ? err->message : "Unknown error"); } } } ... virSetErrorFunc(NULL, libvirt_error_handler); libvirt_connection = virConnectOpen("qemu:///system");...

https://bugzilla.redhat.com/show_bug.cgi?id=912499 (especially comments 7 & 10) This patch set is the final fix so that we can access disks in use by other guests when SELinux and sVirt are enabled. Previously such disks were inaccessible because sVirt labels the disks with a random SELinux label to prevent other instances of qemu from being able to read them. So naturally the libguestfs

Let's actually compile and test the patch this time, rather than trusting the RHEL 7.6 patch to apply directly to head ... Rich.
