The s/1/-1/ fix induces no semantic change, since the sole use of virStateActive tests solely for nonzero.

* src/libvirt.c (virStateActive): Return -1 upon error, not 1, to be consistent with the other virState* functions. (virStateActive, virStateCleanup, virStateReload, virStateActive): Add per-function comments.
NACK.
+/** + * virStateActive + * + * Run each virtualization driver's "active" method. + * + * Return 0 if successful, -1 upon error. + */ int virStateActive(void) { int i, ret = 0;
for (i = 0 ; i < virStateDriverTabCount ; i++) { if (virStateDriverTab[i]->active && virStateDriverTab[i]->active()) - ret = 1; + ret = -1;
This is *not* an error condition. This method is basically asking whether the driver is 'active' - eg, does it have any domains running. It returns 0 if it isn't active, or 1 if it is active. There is no error scenario - it can never fail.
