I have a .cfg configuration file for a xen virtual machine.
I need to convert it in xml format to use with libvirt.
So I run virsh domxml-from-native xen-xm backupsrv.cfg but I have an error:
error: Unknown failure.
How can I investigate about the error?

Have you looked in the logs to see if any further details are present
there? Also, you may want to dial up debug verbosity, using
LIBVIRT_DEBUG and friends, as documented here:
http://libvirt.org/logging.html
Beyond that, all I can suggest is stepping through things with gdb; I'm
not familiar enough with xen myself to recognize these symptoms.

Thanks for your replay.
I've augmented debug level, run virsh domxml-from-native xen-xm
backupsrv.cfg and this is the error:
virsh: malloc.c:3097: sYSMALLOc: Assertion `(old_top == (((mbinptr)
(((char *) &((av)->bins[((1) - 1) * 2])) - __builtin_offsetof (struct
malloc_chunk, fd)))) && old_size == 0) || ((unsigned long) (old_size)
= (unsigned long)((((__builtin_offsetof (struct malloc_chunk,
fd_nextsize))+((2 * (sizeof(size_t))) - 1)) & ~((2 * (sizeof(size_t)))
- 1))) && ((old_top)->size & 0x1) && ((unsigned long)old_end &
pagemask) == 0)' failed.

That's evil :( - this is a failure from glibc, which implies we've
corrupted the heap. Try running things under valgrind to find the culprit.

Also, it might help to post your backupsrv.cfg file, to see if anyone
else can reproduce the failure.

If I do virsh domxml-to-native xen-xm prova.xml it works with no
problems but if I do
virsh domxml-from-native xen-xm backupsrv.cfg I have the error.
Here is my backupsrv.cfg:
