[libvirt] [PATCH 1/3] Fix apparmor issues for Xen

In order for apparmor to work properly in Xen environments, the following access rights need to be allowed: - Allow CAP_SYS_PACCT, which is required when resetting some multi-port Broadcom cards by writting to the PCI config space - Allow CAP_IPC_LOCK, which is required to lock/unlock memory. Without this setting, an error 'Resource temporarily unavailable' can be seen while attempting to mmap memory. At the same time, the following apparmor message is seen: apparmor="DENIED" operation="capable" parent=1 profile="/usr/sbin/libvirtd" pid=2097 comm="libvirtd" pid=2097 comm="libvirtd" capability=14 capname="ipc_lock" - Allow access to distribution specific directories: /usr/{lib,lib64}/xen/bin --- examples/apparmor/usr.sbin.libvirtd | 3 +++ 1 file changed, 3 insertions(+) diff --git a/examples/apparmor/usr.sbin.libvirtd b/examples/apparmor/usr.sbin.libvirtd index 7151052..9917836 100644 --- a/examples/apparmor/usr.sbin.libvirtd +++ b/examples/apparmor/usr.sbin.libvirtd @@ -13,6 +13,7 @@ capability sys_admin, capability sys_module, capability sys_ptrace, + capability sys_pacct, capability sys_nice, capability sys_chroot, capability setuid, @@ -24,6 +25,7 @@ capability mknod, capability fsetid, capability audit_write, + capability ipc_lock, # Needed for vfio capability sys_resource, @@ -45,6 +47,7 @@ /usr/sbin/* PUx, /lib/udev/scsi_id PUx, /usr/{lib,lib64}/xen-common/bin/xen-toolstack PUx, + /usr/{lib,lib64}/xen/bin/* Ux, # force the use of virt-aa-helper audit deny /sbin/apparmor_parser rwxl, -- 1.8.4.5
