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

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.
