This message is a notice that Fedora 19 is now at end of life. Fedora has stopped maintaining and issuing updates for Fedora 19. It is Fedora's policy to close all bug reports from releases that are no longer maintained. Approximately 4 (four) weeks from now this bug will be closed as EOL if it remains open with a Fedora 'version' of '19'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 19 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. Fedora 19 changed to end-of-life (EOL) status on 2015-01-06. Fedora 19 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed. |
Description of problem: Trying to use backing files in a chain with three KVM virtual machines. The structure is: -> server1.example.com.img backing.img -> tester1.backing.img -> tester1.example.com.img -> outsider1.backing.img -> outsider1.example.org.img The SELinux denial came when trying to start tester1.example.com, presumably it doesn't like chains of backing files. SELinux is preventing /usr/bin/qemu-system-x86_64 from 'read' accesses on the file /var/lib/libvirt/images/backing.img. ***** Plugin catchall (100. confidence) suggests *************************** If you believe that qemu-system-x86_64 should be allowed read access on the backing.img 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 system_u:system_r:svirt_t:s0:c163,c593 Target Context system_u:object_r:svirt_image_t:s0:c784,c907 Target Objects /var/lib/libvirt/images/backing.img [ file ] Source qemu-system-x86 Source Path /usr/bin/qemu-system-x86_64 Port <Unknown> Host (removed) Source RPM Packages qemu-system-x86-1.4.2-4.fc19.x86_64 Target RPM Packages Policy RPM selinux-policy-3.12.1-66.fc19.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 3.10.3-300.fc19.x86_64 #1 SMP Fri Jul 26 00:00:58 UTC 2013 x86_64 x86_64 Alert Count 1 First Seen 2013-08-04 16:13:22 BST Last Seen 2013-08-04 16:13:22 BST Local ID 72579721-dcf0-4161-8183-a9ce8c48463e Raw Audit Messages type=AVC msg=audit(1375629202.944:580): avc: denied { read } for pid=4074 comm="qemu-system-x86" name="backing.img" dev="sda1" ino=271159 scontext=system_u:system_r:svirt_t:s0:c163,c593 tcontext=system_u:object_r:svirt_image_t:s0:c784,c907 tclass=file type=SYSCALL msg=audit(1375629202.944:580): arch=x86_64 syscall=open success=no exit=EACCES a0=7fffcf1fb220 a1=80000 a2=0 a3=1 items=0 ppid=1 pid=4074 auid=4294967295 uid=107 gid=107 euid=107 suid=107 fsuid=107 egid=107 sgid=107 fsgid=107 ses=4294967295 tty=(none) comm=qemu-system-x86 exe=/usr/bin/qemu-system-x86_64 subj=system_u:system_r:svirt_t:s0:c163,c593 key=(null) Hash: qemu-system-x86,svirt_t,svirt_image_t,file,read Additional info: reporter: libreport-2.1.5 hashmarkername: setroubleshoot kernel: 3.10.3-300.fc19.x86_64 type: libreport
