Hi, i have a problem with selinux enforced. When i tried to live remove a snapshot the operation failed . After some headache i found the problem source : selinux. When i "setenfore 0" the removal task work, when i "setenforce 1" removal task failed. log from audit.log: vc: denied {write} for pid = 28360 tmptext = system_u: object_r : fixed_disk_device_t: s0 tclass = blk_file I'm with RHEL 7.4 and ovirt 4.1, is it some specific configuration to do?. Thanks for help.
