[libvirt] libvirt strange behavior possibly bug with version 0.7.2

dom.create() 0
dom.destroy() 0
dom.create() Traceback (most recent call last): File "<stdin>", line 1, in ? File "/usr/lib64/python2.4/site-packages/libvirt.py", line 287, in create if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self) libvirt.libvirtError: Unknown failure
Every call to create will raise the same exception, It only works if I do a new connection to the hypervisor. Is there an workaround??

It depends on what you are trying to do. If you have a persistent domain XML that you want to keep, define it once with defineXML and later get access to it with conn.lookupByName() or friends, create(), and finally destroy() it. Anyway, dom.destroy() makes the dom object useless as the name may suggest ;-)
