Description Shevek 2012-02-24 18:45:01 UTC

Description of problem:

libvirt deleted the XML configuration file for a VM after an edit.

Version-Release number of selected component (if applicable):

ii  libvirt-bin                     0.9.2-4ubuntu15                            ii  libvirt0                        0.9.2-4ubuntu15                            

How reproducible: 100%

Steps to Reproduce:
1. Create and define a VM, but do not start it.
2. virsh edit the VM.
3. Change the UUID
4. Save and exit the editor.
5. Error message appears:
error: operation failed: domain 'orchestra' already exists with uuid 4dd4e4bc-ec46-d7b8-5935-cbd727dd89c0
6. Observe XML file in /etc/libvirt/qemu now gone, and never called me mother.
  
Actual results:
XML file vanished, and VM config lost to posterity.

Expected results:
VM config should still exist, with an updated UUID.
libvirt should honour the updated UUID.

Hmm, I tried your steps to reproduce, but I am unable to reproduce this behavior on libvirt 0.9.6.  I see the message about domain already exists with uuid..., but the VM is unaffected following the attempt to edit it.  What version of libvirt are you using?
