Thank you for reporting this -- will take a look. Which VMbackup release version exactly are you running?

0sorkon commented 6 years ago

latest from github v3.22 2017/11/11. on 3.21 september 2017 everything working well.

NAUbackup commented 6 years ago

Might be due to a change in a library definition. That it worked on 3.21 and not on 3.22 is very helpful to know, thank you.

NAUbackup commented 6 years ago

I think the issue is that the global variables xvda_uuid and xvda_name_label are still needed under certain circumstances, but were commented out when going from 3.21 to 3.22:

# global xvda_uuid # global xvda_name_label

should be:

global xvda_uuid
global xvda_name_label

Please try to remove the "#" from the lines from VmBackup.py where those two variables are commented out and see if the script then runs correctly.

yes, after uncommenting line 560,561 global xvda_uuid global xvda_name_label it seems working, thank you

NAUbackup commented 6 years ago

OK, good, thank you. I will make that correction as well as a couple of other minor adjustments and get a new release out in the near future. Glad it's working for you again! --Tobias
