First of all, which specific version of VmBackup is this, or I cannot try to connect the errors with the line numbers?

My guess is that the password contains characters being misinterpreted somehow as part of the command line. You can try enclosing the password in single quotes or creating a password that doesn't contain a "!" or "$"character. The "Authentication failure" error is of course indicating that the attempt to log onto root failed. I get the same error with this password, which of course won't work on my servers.

Did you already edit the configuration file to match your environment?

[melvin0124]

I change the Password ， get the same Authentication Error

[NAUbackup]

I have never seen this happen for the standard root password on a server, so I'm not sure what to suggest. Does test.cfg have any entries in it that might be confusing things? Again, I need to ask which version of VmBackup are you running: 3.21, 3.22, etc. ?

[melvin0124]

NAUbackup Version is v3.22 ， and my xenserver version is 7.1 uc1

[NAUbackup]

Could you perhaps post your entire test.cfg file (sanitized, as necessary)?

[NAUbackup]

There are no VMs or VDIs specified either on the command line or in the file. Could you add one in and try again, please, like:

vm-export=Tocloud-ERP-220

You might also try adding onto the end of the command line:
ignore_extra_keys=True

[melvin0124]

Sorry ， I have already added

[NAUbackup]

I cannot reproduce the error with the same configuration file with the only difference being that I am using one of my own VMs. I'm not sure what else to suggest!

[melvin0124]

Think's I will try other xenserver version

[rtrevino70]

Hellol,, I have the same issue, im running v.3.25
my current password is aaaaaaaaaaaaaa (just lowercase letters (14) )

I made one small change just the other day, changing one dangling https back to http. Try and see if that might help, please.

[rtrevino70]

the only two occurrences in the script are already http. I forgot to mention I am using xcp-ng v8 sorry for this

[NAUbackup]

Hmmm... I'd be curious if a different, perhaps shorter, password works?

[rtrevino70]

Hi,

just changed the password to 5 lowercase letters.. same result

[NAUbackup]

I really have no way to test under XCP-ng, unfortunately, so I'm not sure if its a compatibility issue or what. It seems to work fine under various versions of XenServer. I assume putting the password in double quotes makes no difference, either?

[rtrevino70]

got it to work.!!!

I sent in the clear password instead of the encrypted file. and it is working

./VmBackup.py 'mycurrentlongpassword' config.cfg

cheers!

[NAUbackup]

Ah, great to hear! Maybe the encryption algorithm isn't working right? Could someone else test this on XenServer/CitrixHypervisor with V3.25?

[sfitzpsp]

Hi there,

im trying this on Citrix Hypervisor 8.0 standard fully patched and getting the same error. If i provide the password as argument it works but not when using password file.

I was also using the latest SDK XenAPI which might be the issue?
