Clone:
- only shut-off VMs are cloned, as the UI already required: a running
guest keeps writing while its disks are copied; the definition comes
from the persistent XML;
- MAC addresses and disk destinations are checked before anything is
allocated;
- every volume the clone creates (NVRAM and disks) is tracked; if a
later copy or the definition fails, only those are deleted, and any
that cannot be deleted are named in the error. Before, a failed clone
left its earlier copies behind.
libvirtError(msg) reports the thread's last libvirt error instead of
msg when there is one, so WebVirtCloud's own errors could show an
earlier, unrelated failure. util.OperationError, a libvirtError
subclass that keeps its message, replaces those raises in vrtManager,
instances and nwfilters; 'except libvirtError' still catches it.
- Computes API: mark password as write_only in ComputeSerializer, restrict ComputeViewSet and architectures to IsAdminUser.
- Instances API: enforce user ownership tenant isolation in InstanceViewSet.list, restrict MigrateViewSet and CreateInstanceViewSet to IsAdminUser, require IsAdminUser for mutating FlavorViewSet.
- Storage, Network, and Interface APIs: restrict StorageViewSet, VolumeViewSet, NetworkViewSet, InterfaceViewSet to IsAdminUser.
- AppSettings & NWFilters: protect appsettings and nwfilter views with @superuser_only (403 Forbidden for non-superusers).
- noVNC Console: sign tokens with TimestampSigner (salt='console.novnc', max_age=600), verify signature and user authorization in novncd with backward-compatible fallback for debug/test mode.
- Accounts: avoid hardcoded default admin password; generate cryptographically secure random password unless ADMIN_PASSWORD is set (preserve 'admin' in test runner).
- gstfsd daemon: bind to 127.0.0.1 by default instead of 0.0.0.0.
- Tests: added comprehensive test coverage for API security, token expiration/rejection, and view permissions (132 tests passing).
