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.

That's evil :( - this is a failure from glibc, which implies we've

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:
