Original GitHub issue: https://github.com/retspen/webvirtcloud/issues/372

Hi:
I am trying migrate the VM 'cirros' from node1 to node2 with 'unsafe' option recently. The VM migration was successfully completed. But when I check instances status from the browser, I found there were two VM 'cirros' on the list with the same settings. The results was captured as the attachment picture.
question

Is there any solution for this situation?
Thanks for your helping.

Is there any special situation for using unsafe migration?
After migration completed, it is an option undefining source or not.

I am testing block migration on Ubuntu server. I found WebVirtCloud is so easy to install, configure and use. So I tested all function of WebVirtCloud in my environment. Because there is no shared storage in the environment, so I test VM migration with 'unsafe' option. Then the strange situation. migrated VM displayed in Instances page twice, was appeared.
I even tried to remove the duplicate VM record from the table of 'instances_instance'. But that wasn't work, the record would insert into database again.
BTW, thanks for your response.

hi, i tested it again. there is not any problem with it. you should always check "Delete Original"="undefine source", if you do not have special purpose.

Hi, catborise:
I enable the options of 'Unsafe live migration', 'Delete original', and the 'Instances' listing is ok now.
Thanks for your helping.
