Hi Pádraig, thank you for your quick answer and suggestions.After some investigation I discovered that guestfs fails to mount the image because selinux: type=AVC msg=audit(1352816002.979:249317): avc: denied { read } for pid=2806 comm="qemu-kvm" name="disk" dev=dm-3 ino=656740 scontext=unconfined_u:system_r:qemu_t:s0-s0:c0.c1023 tcontext=unconfined_u:object_r:nova_var_lib_t:s0 tclass=file type=SYSCALL msg=audit(1352816002.979:249317): arch=c000003e syscall=2 success=no exit=-13 a0=7fae966dbc20 a1=800 a2=0 a3=65636e6174736e69 items=0 ppid=2797 pid=2806 auid=0 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=19511 comm="qemu-kvm" exe="/usr/libexec/qemu-kvm" subj=unconfined_u:system_r:qemu_t:s0-s0:c0.c1023 key=(null) type=AVC msg=audit(1352816002.980:249318): avc: denied { getattr } for pid=2806 comm="qemu-kvm" path="/var/lib/nova/instances/instance-000000a7/disk" dev=dm-3 ino=656740 scontext=unconfined_u:system_r:qemu_t:s0-s0:c0.c1023 tcontext=unconfined_u:object_r:nova_var_lib_t:s0 tclass=file type=SYSCALL msg=audit(1352816002.980:249318): arch=c000003e syscall=4 success=no exit=-13 a0=7fae966dbc20 a1=7fffedb37730 a2=7fffedb37730 a3=65636e6174736e69 items=0 ppid=2797 pid=2806 auid=0 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=19511 comm="qemu-kvm" exe="/usr/libexec/qemu-kvm" subj=unconfined_u:system_r:qemu_t:s0-s0:c0.c1023 key=(null) type=AVC msg=audit(1352816002.980:249319): avc: denied { read } for pid=2806 comm="qemu-kvm" name="disk" dev=dm-3 ino=656740 scontext=unconfined_u:system_r:qemu_t:s0-s0:c0.c1023 tcontext=unconfined_u:object_r:nova_var_lib_t:s0 tclass=file Disabling selinux it works fine. Should I open a bug for this?
Probably. Let's get details first. Can you renable SElinux, and then: setsebool -P allow_unconfined_qemu_transition 0 Does that minimal SELinux relaxation allow libguestfs to work? thanks, Pǽdraig. _______________________________________________ cloud mailing list [email protected] https://admin.fedoraproject.org/mailman/listinfo/cloud
