Hi
Thanks for your help. I will provide all log files a little bit later, but
so far I have noticed some pattern when migration fails. Those particular
VMs, which fails to migrate, were installed from ISO image, usual
installation. So, I believe you can reproduce the issue by this:
1. Upload ISO image to ISO domain
2. Install new OS by booting from ISO image and check Attach CD in Boot
Options
3. Delete ISO image from ISO domain
4. Try to migrate VM to another host.
I have not tried this yet, but I have noticed that only those VMs fails
which had been install from ISO image which is not in ISO domain anymore. I
have also VMs created from templates and those VMs I can migrate just fine.
I will provide more log files later.
BR
Edgars
