Description of problem:
This is extended version of BZ1588555, I tried to migrate vm with vmname `ytale-v2v-ubuntu-nfs-punycode-джум-ññ` and it failed to migrate. 

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

How reproducible:

Steps to Reproduce:
1. Try to migrate vm with punycode characters in their name
(Infra mapping was normal, for datastores I used nfs at source and nfs at target, I don't think it is matter of datastore)

Actual results:
Error while migrating vm

Expected results:
VM name with punycode characters should also be get migrated

Additional info:
Automation.log attached.

What's interesting is that virt-v2v is up and running.  It appears
that the wrapper is reading the logs from virt-v2v and the wrapper
hits the parse error noted by KK.

Does the wrapper or Python expect that the output of virt-v2v
(especially debugging output) is always going to contain valid
UTF-8?  I'm afraid that's not a valid assumption.  Debug messages
will print all kinds of internal strings, and some of these won't
be well-formed UTF-8 (or necessarily any encoding).

Comment 9 Tomáš Golembiovský 2018-07-31 14:44:22 UTC
This has been fixed in wrapper and will be available in next build

Comment 10 Tomáš Golembiovský 2018-08-01 11:23:17 UTC
Fixed in wrapper. Build: ovirt-ansible-v2v-conversion-host-1.6.0-1.el7ev

Comment 11 Brett Thurber 2018-08-08 14:24:33 UTC
@Ytale can you verify with 4.2.6 preview?

@Brett, checked on 4.6.2's appliance (assuming comment #11 as a typo).
Used vm name `ytale-v2v-طدЩыǪἀ-джум-简体中文-日本語-pê-añ-ça` with following requirements.

vcenter: 6.5
wrapper: ovirt-ansible-v2v-conversion-host-1.5.0-1.el7ev.noarch

Able to to migrate vm successfully.

> Able to to migrate vm successfully.

This is rather intersting. Fixed wrapper is in version 1.6.0.

Comment 14 Tomáš Golembiovský 2018-08-09 13:31:24 UTC
Ok, I realized why it did work. There are two different potential issues at play here.

1) the VM name contains special characters
2) the disk path of the disk in VM contains special characters

Normally, the disk paths are based on VM name so the two issues may seamingly become one issues. But they are really two different problems. To my knowledge 1) was never a problem with the wrapper, but the 2) caused the migration to fail in wrapper. Also, 2) has that fix in 1.6.0 and is tracked by bug 1581739.

I'm not sure whether this particular bug should be about 1) or 2) or both... you decide.

Comment 15 Yadnyawalk Tale 2018-10-03 12:40:13 UTC
Fixed! Vm name with internationalization characters (punycodes) works well with patch.

Verified with:
Wrapper - ovirt-ansible-v2v-conversion-host-1.6.3-1.el7ev
vSphere - 6.7.0

Comment 16 Yadnyawalk Tale 2018-10-03 13:49:47 UTC
This issue was intentionally opened for punycode thing and not for special characters. I did checked special characters thing while checking punycode and it failed.

More info related to special char will be on
