Migration from Proxmox
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)? * https://rwmj.wordpress.com/2015/09/18/importing-kvm- guests-to-ovirt-or-rhev/ Thanks in Advance!

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?usp=s... Then you select your image on local disk (or share...): https://drive.google.com/file/d/16HBE6VnfO_P3xsqi_16ae4yHh__7G4FS/view?usp=s... 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) # engine-setup [ INFO ] Stage: Initializing [ INFO ] Stage: Environment setup Configuration files: ['/etc/ovirt-engine-setup.conf.d/10-packaging-jboss.conf', '/etc/ovirt-engine-setup.conf.d/10-packaging.conf', '/etc/ovirt-engine-setup.conf.d/20-setup-ovirt-post.conf'] Log file: /var/log/ovirt-engine/setup/ovirt-engine-setup-20171114112028-cyi1ot.log Version: otopi-1.6.2 (otopi-1.6.2-1.el7.centos) [ INFO ] Stage: Environment packages setup [ INFO ] Stage: Programs detection [ INFO ] Stage: Environment setup [ INFO ] Stage: Environment customization --== PRODUCT OPTIONS ==-- . . . --== CONFIGURATION PREVIEW ==-- . . . Configure Image I/O Proxy : True . . . 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 On engine: $ sudo systemctl status ovirt-imageio-proxy.service -l ● ovirt-imageio-proxy.service - oVirt ImageIO Proxy Loaded: loaded (/usr/lib/systemd/system/ovirt-imageio-proxy.service; enabled; vendor preset: disabled) Active: active (running) since Tue 2017-11-14 11:36:30 CET; 2 weeks 3 days ago Main PID: 664 (ovirt-imageio-p) CGroup: /system.slice/ovirt-imageio-proxy.service └─664 /usr/bin/python /usr/bin/ovirt-imageio-proxy Nov 14 11:36:29 engine.mydomain.it systemd[1]: Starting oVirt ImageIO Proxy...

Well, now I have a new problem... Uploading a qcow2 gets paused and I receive an error: *Unable to upload image to disk 11112a70-4cbe-4612-a5e2-101717cb08a3 due to a network error.

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)?

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!

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!
