Description Ilanit Stein 2019-07-02 09:59:02 UTC 
Description of problem:
On CFME-5.10.6.1 we are missing logging that indicate why a specific conversion host is picked for VM migration.

Adding logging can help, in investigating issues, around this area.

Version-Release number of selected component (if applicable):
CFME-5.10.6.1

Comment 4 Ilanit Stein 2019-08-11 19:10:00 UTC 
Verified on CFME-5.11.0.18.20190806180636_1dd6378/RHV-4.3.5.3-0.1.el7
+ [1] & [2] additions.

evm.log contain debug messages, that provide info on the chosen host, for conversion.
Examples:

[1] To allow conversion host enable, uUsed work around mentioned in this bug description:
Bug 1738643 - [v2v][Regression] Can not add conversion host due to playbook errors
[2] To allow successful migration, used libguestfs special packages:
libguestfs libguestfs-tools-c virt-v2v python-libguestfs
