[libvirt-users] how to convert from xen .cfg files to libvirt xml?
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. -- Eric Blake eblake@redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org
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. -- Eric Blake eblake@redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org

Also, it might help to post your backupsrv.cfg file, to see if anyone else can reproduce the failure. -- Eric Blake eblake@redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org

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: # # Configuration file for the Xen instance backupsrv, created # by xen-tools 4.2 on Mon Sep 26 13:29:57 2011. # # # Kernel + memory size # bootloader = '/usr/lib/xen-default/bin/pygrub' vcpus = '1' memory = '1024' # # Disk device(s). # root = '/dev/xvda2 ro' disk = [ 'phy:/dev/vg-xen-domUs/backupsrv-disk,xvda2,w', 'phy:/dev/vg-xen-domUs/backupsrv-swap,xvda1,w', ] # # Physical volumes # # # Hostname # name = 'backupsrv' # # Networking # vif = [ 'ip=192.168.245.10,mac=00:16:3E:65:8E:86,bridge=xenbr.119' ] # # Behaviour # on_poweroff = 'destroy' on_reboot = 'restart' on_crash = 'restart'
