Could you try it with #semodule -B re-test and #ausearch -m avc,user_avc -ts recent SELinux is preventing qemu-system-x86 from ioctl access on the chr_file /dev/net/tun. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that qemu-system-x86 should be allowed ioctl access on the tun chr_file 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: # grep qemu-system-x86 /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context unconfined_u:unconfined_r:svirt_t:s0:c393,c538 Target Context system_u:object_r:svirt_image_t:s0:c295,c359 Target Objects /dev/net/tun [ chr_file ] Source qemu-system-x86 Source Path qemu-system-x86 Port <Unknown> Host localhost.localdomain Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.13.1-79.fc21.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Permissive Host Name localhost.localdomain Platform Linux localhost.localdomain 3.16.1-301.fc21.x86_64 #1 SMP Mon Aug 25 13:06:39 UTC 2014 x86_64 x86_64 Alert Count 1 First Seen 2014-09-11 08:06:10 EDT Last Seen 2014-09-11 08:06:10 EDT Local ID ec18c60c-bcf2-49c8-a4fb-91ff660bdc29 Raw Audit Messages type=AVC msg=audit(1410437170.925:604): avc: denied { ioctl } for pid=22476 comm="qemu-system-x86" path="/dev/net/tun" dev="devtmpfs" ino=12606 scontext=unconfined_u:unconfined_r:svirt_t:s0:c393,c538 tcontext=system_u:object_r:svirt_image_t:s0:c295,c359 tclass=chr_file permissive=1 Hash: qemu-system-x86,svirt_t,svirt_image_t,chr_file,ioctl Yes, we know about this issue. It is caused by libvirtd fixes. We probably will need to allow virtd_t to access tun_socket for svirt_t for F21 until we get a libvirt solution. I also have issues starting VM in boxes on f21, not sure how to check is it the same issue? When I 'setenforce 0' it "works" starts VM, but I think there are other boxes issues.
