Hello, I have to do a test on Oracle VM 3.4.4 that is based on Xen 4.4.4. The test aims in simulating storage migration in OVM, where I have to migrate also the so called server pool file system, that requires a special procedure. I see that some guys wrote here to ask about OVM to oVirt migrations, so there could be some expertise in this field. I'm just trying to proceed with the hypervisor steps (Oracle VM Server), that is the more difficult part, I suppose. I'm testing at the moment on a Fedora 29 system, using qemu-kvm, setting host-pass-through for the vm dedicated to the Oracle VM Hypervisor. I already tested nested virtualization (with oVirt for some vms) inside this system, so the host part should be ok. I have set disks as scsi and vnic as e1000 Installation gone ok but at reboot I see cpu stuck and no prompt yet see here: https://drive.google.com/file/d/1sAEO-W0-OLIGSugxIwSLRBx3WXXoK1yx/view?us... I have not yet understood exactly the reason of complain... Any one already able to create a Xen (or Oracle VM) nested environment inside qemu-kvm? The OS of the Xen dom0 should be based on Oracle Linux 6.x I can also test trying to install on oVirt if anyone on the list already ran through this path. Thanks in advance for any help or pointers. I'm also going and post on Oracle VM forum... Gianluca
