Hello, I recently had to reinstall my operating system on my computer. I made a backup of the entire partition beforehand onto an external drive. Now I am trying to import a VM from that backup onto the newly installed system. What I've done so far: * copied over the qcow2 disk image * copied over the XML config file * copied over the OVMF files under /usr/share/edk2.git/ovmf-x64/ I am getting this error whenever I try to boot the VM: Error starting domain: operation failed: unable to find any master var store for loader: /usr/share/edk2.git/ovmf-x64/OVMF_CODE-pure-efi.fd The file /usr/share/edk2.git/ovmf-x64/OVMF_CODE-pure-efi.fd does exist. Where would the "master var store" be located?

Anyway, Aleksei is right that you should copy over the variable store (vm_VARS.fd) along with the disk image and the XML configuration: some guest operating systems are able to cope with its absence and recreate the correct EFI variables automatically, but that's not always the case. Moreover, you should make sure your /etc/libvirt/qemu.conf file contains something along the lines of nvram = [ "/usr/share/edk2.git/ovmf-x64/OVMF_CODE-pure-efi.fd:/ usr/share/edk2.git/ovmf-x64/OVMF_CODE-pure-efi.fd/OVMF_VARS-pure-efi.fd" ] so that, in case the variable store for the guest is missing or your simply creating a new guest, libvirt will be able to create a new one by copying over the template (the "master var store" the error was referring to). By the way, edk2-ovmf is included in Fedora proper these days, you don't need to use edk2.git-ovmf-x64 any longer ;) -- Andrea Bolognani / Red Hat / Virtualization
