There appears to be some type of apparmor profile issue between libvirt and xenner. Xenner is expected to be a valid emulator callable by libvirt.
Here's what I see even after unloading apparmor: + apparmor_status apparmor module is loaded. 0 profiles are loaded. 0 profiles are in enforce mode. 0 profiles are in complain mode. 0 processes have profiles defined. 0 processes are in enforce mode : 0 processes are in complain mode. 0 processes are unconfined but have a profile defined. + virsh start Ubuntu-domU-x86-1 Connecting to uri: qemu:///system error: Failed to start domain Ubuntu-domU-x86-1 error: internal error unable to start guest: libvir: error : cannot execute binary /usr/bin/xenner: Permission denied + tail /var/log/kern.log Dec 15 13:18:54 grp-01-23-02 kernel: [ 5147.595329] type=1505 audit(1260901134.725:32): operation="profile_load" pid=13204 name=libvirt-74367128-9bd6-3264-3833-f661c47b464e Dec 15 13:18:54 grp-01-23-02 kernel: [ 5147.598647] device vnet0 entered promiscuous mode Dec 15 13:18:54 grp-01-23-02 kernel: [ 5147.599664] br0: port 2(vnet0) entering learning state Dec 15 13:18:54 grp-01-23-02 kernel: [ 5147.600812] type=1503 audit(1260901134.735:33): operation="exec" pid=13208 parent=13207 profile="libvirt-74367128-9bd6-3264-3833-f661c47b464e" requested_mask="x::" denied_mask="x::" fsuid=0 ouid=0 name="/usr/bin/xenner" Dec 15 13:18:54 grp-01-23-02 kernel: [ 5147.644365] br0: port 2(vnet0) entering disabled state Dec 15 13:18:54 grp-01-23-02 kernel: [ 5147.683450] device vnet0 left promiscuous mode Dec 15 13:18:54 grp-01-23-02 kernel: [ 5147.683454] br0: port 2(vnet0) entering disabled state Dec 15 13:18:54 grp-01-23-02 kernel: [ 5147.828181] type=1505 audit(1260901134.957:34): operation="profile_remove" pid=13210 name=libvirt-74367128-9bd6-3264-3833-f661c47b464e namespace=default Even with apparmor unloaded the kernel still loads a profile, denies access and then removes the profile. Maybe this is some type of apparmor bug or a kernel bug. Or maybe there needs to be an apparmor profile setting in the xenner package. -- Ubuntu Server 9.10 (karmic): xenner: depends on non-existent library https://bugs.launchpad.net/bugs/496654 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
