RHV is basically oVirt (open source). Once you have the qcow exported from RHV, you can import this into Openstack as an image and deploy it there. I'd suggest that you can deploy oVirt in a single machine and run some tests from there. </div><div class="gmail_default" style="font-family:verdana,sans-serif;color:rgb(102,102,102)">Most of my VMs on RHV I run with a single disk for simplicity reasons mostly. What confuses me about your mail is that you have a Windows VM with /lv and /boot and these sound like unix partitions. Maybe the /boot qcow is where the boot loader resides.. no idea. </div><div class="gmail_default" style="font-family:verdana,sans-serif;color:rgb(102,102,102)"><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;color:rgb(102,102,102)">If you can deploy ovirt then you can deploy a windows VM on a single disk then export this and import to Openstack to get familiar which is what I would do in that situation. </div><div class="gmail_default" style="font-family:verdana,sans-serif;color:rgb(102,102,102)"><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;color:rgb(102,102,102)">Tip; On any of your disk images you can use `qemu-img info filename.qcow` to get information about the disk image, such as format and size in case it helps. You can also convert this data (such as converting to VHD for Azure) (I am just mentioning this as an FYI).</div><div class="gmail_default" style="font-family:verdana,sans-serif;color:rgb(102,102,102)"><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;color:rgb(102,102,102)">You probably wont "combine" those files but instead, you would create a VM "profile" that has those three disks. I expect that the vendor was running a VM in RHV with three disks so this is what they have sent to you. </div><div class="gmail_default" style="font-family:verdana,sans-serif;color:rgb(102,102,102)"><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;color:rgb(102,102,102)">HTH</div><div class="gmail_default" style="font-family:verdana,sans-serif;color:rgb(102,102,102)"><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;color:rgb(102,102,102)">Regards,</div><div class="gmail_default" style="font-family:verdana,sans-serif;color:rgb(102,102,102)"><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;color:rgb(102,102,102)"><br></div><div><div dir="ltr" class="gmail_signature"><div dir="ltr"><div>Tony Pearce<br><br></div></div></div></div></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Mon, 19 Jul 2021 at 13:26, KK CHN <<a href="mailto:kkchn.in@gmail.com">kkchn.in@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div> </div><div>QUERY Section A:</div><div><br></div>We are in the process of migrating VMs from a Vendor to OpenStack . <div><br></div><div>The Vendor has hosted the VMs using RedHat Virtualization and HyperV around 100 VMs. Each VM size varies from 50 GB to 150 GB size. </div><div><br></div><div><br></div><div>What is the best way to migrate these VMs to New Hardware infra Installed with OpenStack Ussuri. </div><div><br></div><div>What need to be done at the existing live VMs with the Vendor and in what file format we have to ask the vendor to give the snapshot of VMs to be migrated ?</div><div><br></div><div>I am new to the migration of VMs from a live production setup ( the present Vendor deployed VMs with all aplications running on the VM with HyperV and RedeHat KVM. )</div><div><br></div><div>We are also using KVM hypervisor.</div><div><br></div><div>Kindly advise and direct me with all good practices followed to perform this migration from existing vendor to our own setup with OpenStack and KVM.</div><div><br></div><div>Pls shed some light on this. </div><div><br></div><div>QUERY SECTION B</div><div><br></div><div> Another question below</div><div><br></div><div>ffor a trail the existing vendor has given a demo VM, which is a Windows VM with an ERP application hosted on it .
