My guess is that your xapi database has been corrupted, if you dont have a backup this will be a rough one.
To add some content I'll summarize what you wrote on IRC:
You got an error, it was not resolved.
You then decided to start upgrading your xcp installation
Now the database is corrupt, not sure it it was already or if it happend in step 2.
