Hi again!
well, I'm trying to migrate all my VMs from Proxmox to oVirt. Proxmox
doesn't have libvirt and I can dump the files using vzdump <vm-id>
<directory> and the output is a *.vma file I think from Proxmox. I can't
even find the files, Proxmox create Logical Volumes for every VM.
I converted that to *.qcow2 using qemu-img convert, the conversion
worked(at least no errors) but I can't import it using a script that I
found on web* and the export storage domain(oVirt didn't found it).
I would like to know if there is a way to do that. I read a lot about and
found that one could build a conversion server and use virt-v2v to import.
But it will require a RH Enterprise for that, right? I don't have a
subscription and I would like to know if is possible without the
subscription?
And sorry for the offtopic question, if there is a "redhat" which would
like to answer me privately, if I buy a subscription for 1 Server and I
have NN CentOS Servers, it will be possible to use all benefits since I
have a valid subscription(of course, support just for the RH Server)?

If you already converted from LV to img file, in recent versions of oVirt
you can upload virtual disks from your client to the oVirt infrastructure,
while connected to the web admin gui with a browser.
Under disks --> upload:
https://drive.google.com/file/d/1DopgiOZ82Zc-W3IYGns1_QQ7JrFF_DUS/view?us...
Then you select your image on local disk (or share...):
https://drive.google.com/file/d/16HBE6VnfO_P3xsqi_16ae4yHh__7G4FS/view?us...
NOTE: I don't know why you are asked to input the size of the disk at
destination....
Please note that you have to enable the Image I/O Proxy service on engine
during engine-setup (you can re-run engine-setup also to change
configuration settings if you didn't enabled it at installation time)

and that the client where you run firefox needs to be able to connect to
port 54323 of the engine server to upload the file

Then you can create a VM and assign this imported floating disk to it.

Well, now I have a new problem...
Uploading a qcow2 gets paused and I receive an error:

Question: I saw that there is a imageio-proxy and imageio-daemon. Proxy is
installed on hosted-engine, and imageio-daemon on host.
I installed imageio-daemon on hosted-engine(and I think that was a mistake)
but there isn't a vdsmcert.pem there, just on hosts with vdsm and
hosted-engine installed.
Ports are already on firewall, 54323/tcp right?
On Host:
# systemctl status ovirt-imageio-daemon
● ovirt-imageio-daemon.service - oVirt ImageIO Daemon
Loaded: loaded (/usr/lib/systemd/system/ovirt-imageio-daemon.service;
disabled; vendor preset: disabled)
Active: active (running) since So 2017-11-26 23:26:03 CET; 4 days ago
Main PID: 21034 (ovirt-imageio-d)
CGroup: /system.slice/ovirt-imageio-daemon.service
└─21034 /usr/bin/python /usr/bin/ovirt-imageio-daemon
Am I doing something wrong? Installation from hosted-engine and host are
quite normal, no custom stuff.
Thanks!

Solved!
On Hosted Engine:
tail -f /var/log/ovirt-imageio-proxy/image-proxy.log
Look which Host is on 'no route to host' and firewall-cmd --permanent
--add-port=54322/tcp && firewall-cmd --reload
Uploading now and I will test!
Thanks!

Migration worked!
Please feel free to copy on Blogs, Wikis and so on!
There is a better way probably(Libvirt on another Server/Linux Workstation
an import through KVM), but this just works.
=> How to Migrate VMs from Proxmox:
Requirements:
- Port 54322/tcp open on oVirt Hosts
- ovirt-imageio-daemon running on Hosts
- ovirt-imageio-proxy running on (Hosted)-Engine.
-- Attention: this will move disks through different Storages from Proxmox.
--
1 - Add a Storage to Proxmox, like NFS or a local share.
2 - Click on a VM from Proxmox and choose the option "Move Disk" on the
taskbar above.
3 - Choose qcow2 as a export file and save the file on the added storage.
4 - On oVirt-Engine go to Disks and click on Upload(Taskbar above) and add
the size of disk from Proxmox( to check how big it is: on Proxmox through
"Hardware" on the left sidebar from VM).
5 - Create a new VM and attach the qcow2 disk.
6 - Check the Network Configs, if you did something with udev-rules you
will need to change the mac address.
Many Thanks to Gianluca and Nathanäel!
Best Regards,
Gabriel
