Changing version to '9' as part of upcoming Fedora 9 GA. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping This message is a reminder that Fedora 9 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 9. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '9'. 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 prior to Fedora 9's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 9 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 please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. 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. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping This is fixed in the current release. |
On rawhide, doing: $> ./virsh list libvir: Remote error : remoteDispatchClientRequest: internal error: library function returned error but did not set virterror libvir: warning : Failed to find the network: Is the daemon running ? Id Name State ---------------------------------- 0 Domain-0 running the warning goes away with SELinux in permissive mode Denial details: SELinux is preventing libvirtd (virtd_t) "dac_override" to <Unknown> (virtd_t). host=zig type=AVC msg=audit(1203074426.175:139): avc: denied { dac_override } for pid=2437 comm="libvirtd" capability=1 scontext=system_u:system_r:virtd_t:s0 tcontext=system_u:system_r:virtd_t:s0 tclass=capability host=zig type=SYSCALL msg=audit(1203074426.175:139): arch=40000003 syscall=5 success=no exit=-13 a0=71161c a1=2 a2=20bc0 a3=91fb5c0 items=0 ppid=1 pid=2437 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) comm="libvirtd" exe="/usr/sbin/libvirtd" subj=system_u:system_r:virtd_t:s0 key=(null) If I allow that, then I get: SELinux is preventing libvirtd (virtd_t) "read" to ./privcmd (proc_xen_t). host=zig type=AVC msg=audit(1203075507.240:186): avc: denied { read } for pid=2437 comm="libvirtd" name="privcmd" dev=proc ino=-268434280 scontext=system_u:system_r:virtd_t:s0 tcontext=system_u:object_r:proc_xen_t:s0 tclass=file host=zig type=SYSCALL msg=audit(1203075507.240:186): arch=40000003 syscall=5 success=no exit=-13 a0=71161c a1=2 a2=20bc0 a3=91fb5d0 items=0 ppid=1 pid=2437 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) comm="libvirtd" exe="/usr/sbin/libvirtd" subj=system_u:system_r:virtd_t:s0 key=(null) Allowing that makes the warning go away Both denials result in: open("/proc/xen/privcmd", O_RDWR) = -1 EACCES (Permission denied)
