From: ShaoHe Feng <shaohef@linux.vnet.ibm.com> V3 -> V4 update test case V2 -> V3 sort the import. V1 -> V2 use debug to log the open exception trace stack. It is complex to check the permission for qemu user. There are too many access controlling mechanisms in Linux, such as ACL, traditional ugo+-rwx, SELinux and AppArmor. It's not possible to enumerate and check every access mechanisms if it allows QEMU to access a file. So now I'm simply trying to access the file with qemu user and see if it's OK It is simple and avoid handling corner case. Also I can try to start a simple guest with the given iso. ShaoHe Feng (4): add a method to probe the permission as qemu user qemu user tests: probe the username of qemu process started by libvirt Don't allow templates to be created with ISOs that won't be usable. probe iso permission: update test case Makefile.am | 1 + src/kimchi/i18n.py | 5 ++++ src/kimchi/kvmusertests.py | 64 +++++++++++++++++++++++++++++++++++++++++++ src/kimchi/model/templates.py | 13 ++++++++- src/kimchi/utils.py | 26 ++++++++++++++++++ tests/test_model.py | 38 ++++++++++++++++--------- 6 files changed, 133 insertions(+), 14 deletions(-) create mode 100644 src/kimchi/kvmusertests.py -- 1.8.4.2
