Description of problem: SELinux is preventing qemu-system-x86 from using the 'execmem' accesses on a process. ***** Plugin catchall_boolean (89.3 confidence) suggests ****************** If you want to allow virt to use execmem Then you must tell SELinux about this by enabling the 'virt_use_execmem' boolean. Do setsebool -P virt_use_execmem 1 ***** Plugin catchall (11.6 confidence) suggests ************************** If you believe that qemu-system-x86 should be allowed execmem access on processes labeled svirt_t by default. Then you should report this as a bug. You can generate a local policy module to allow this access. Do allow this access for now by executing: # ausearch -c 'qemu-system-x86' --raw | audit2allow -M my-qemusystemx86 # semodule -X 300 -i my-qemusystemx86.pp Additional Information: Source Context unconfined_u:unconfined_r:svirt_t:s0:c115,c493 Target Context unconfined_u:unconfined_r:svirt_t:s0:c115,c493 Target Objects Unknown [ process ] Source qemu-system-x86 Source Path qemu-system-x86 Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.13.1-257.fc26.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 4.11.6-300.fc26.x86_64 #1 SMP Mon Jun 19 17:19:26 UTC 2017 x86_64 x86_64 Alert Count 1 First Seen 2017-06-21 16:08:59 CEST Last Seen 2017-06-21 16:08:59 CEST Local ID fe877ac1-3fc9-42c9-9c35-4a8381a994d8 Raw Audit Messages type=AVC msg=audit(1498054139.187:341): avc: denied { execmem } for pid=23216 comm="qemu-system-x86" scontext=unconfined_u:unconfined_r:svirt_t:s0:c115,c493 tcontext=unconfined_u:unconfined_r:svirt_t:s0:c115,c493 tclass=process permissive=0 Hash: qemu-system-x86,svirt_t,svirt_t,process,execmem Version-Release number of selected component: selinux-policy-3.13.1-257.fc26.noarch Additional info: component: selinux-policy reporter: libreport-2.9.1 hashmarkername: setroubleshoot kernel: 4.11.6-300.fc26.x86_64 type: libreport Potential duplicate: bug 1159823
