(1) Check for 404 errors from xend and turn them into VIR_ERR_NO_DOMAIN (currently they are VIR_ERR_POST_FAILED). You'll typically see this when you have a handle to a domain, but the underlying domain is shutdown, as in this example: $ python Python 2.4.3 (#1, Dec 11 2006, 11:39:03) [GCC 4.1.1 20061130 (Red Hat 4.1.1-43)] on linux2 Type "help", "copyright", "credits" or "license" for more information. libvir: Xen Daemon error : Domain not found: No such domain fc6_6 Traceback (most recent call last): File "<stdin>", line 1, in ? File "/home/rjones/local/lib/python2.4/site-packages/libvirt.py", line 359, in suspend if ret == -1: raise libvirtError ('virDomainSuspend() failed', dom=self) libvirt.libvirtError: virDomainSuspend() failed Domain not found: No such domain fc6_6 (2) There was a case where xend was returning an error, but we didn't translate that into an error return code (-1). I'm sure this is an oversight, and the patch fixes it.
