Description of problem: Trying to create a simple wrapper: $ cat /usr/libexec/qemu-kvm.foo #!/bin/sh exec /usr/libexec/qemu-kvm "$@" And setting permissions via restorecon: $ ls -Z /usr/libexec/qemu-kvm* -rwxr-xr-x. root root system_u:object_r:qemu_exec_t:s0 /usr/libexec/qemu-kvm -rwxr-xr-x. root root system_u:object_r:qemu_exec_t:s0 /usr/libexec/qemu-kvm.foo Results in exec_no_trans errors in audit.log. audit2allow resolves the problem. As the transition is safe, selinux should allow this by default. Version-Release number of selected component (if applicable): selinux-policy-3.7.19-42.el6.noarch How reproducible: 100% Steps to Reproduce: 1. See description above 2. virsh edit <guest domain> # point emulator at qemu-kvm.foo 3. virst start <guest domain> Actual results: Fail, audit.log error Expected results: Works Additional info: This is the change that seems to make it work: module qemutxtimer 1.0; require { type svirt_t; type qemu_exec_t; type qemu_t; class file execute_no_trans; } #============= qemu_t ============== #!!!! This avc is allowed in the current policy allow qemu_t qemu_exec_t:file execute_no_trans; #============= svirt_t ============== allow svirt_t qemu_exec_t:file execute_no_trans;
