Luiz wondered whether this would affect x86_64 in addition to aarch64, and as it turns out it does: if your guest definition looks like <domain type='kvm'> <os> <type arch='x86_64' machine='pc-q35-rhel8.2.0'>hvm</type> <loader readonly='yes' secure='yes' type='pflash'>/usr/share/edk2/ovmf/OVMF_CODE.secboot.fd</loader> <nvram>/var/lib/libvirt/qemu/nvram/guest_VARS.fd</nvram> </os> ... which is what you'd get out of a virt-install call along the lines of $ virt-install --os-variant rhel8.0 --boot uefi ... then you'll experience the same issue on migration: $ virsh migrate guest qemu+ssh://dst/system error: operation failed: unable to find any master var store for loader: /usr/share/edk2/ovmf/OVMF_CODE.secboot.fd Verified Version: libvirt-6.0.0-30.module+el8.4.0+8705+34397d87.x86_64 qemu-kvm-4.2.0-35.module+el8.4.0+8705+34397d87.x86_64 S1: Migrate a OVMF domain 1. Prepare the migration environment with two servers(src and dst). 2. Install a ovmf guest by virt-install. # virt-install --name ovmf --memory 4096 --disk /var/lib/libvirt/images/lmn-ovmf.qcow2,size=20 --boot uefi --os-variant rhel8.0 # virsh dumpxml ovmf | grep /os -B 5 <os> <type arch='x86_64' machine='pc-q35-rhel8.2.0'>hvm</type> <loader readonly='yes' secure='yes' type='pflash'>/usr/share/edk2/ovmf/OVMF_CODE.secboot.fd</loader> <nvram>/var/lib/libvirt/qemu/nvram/ovmf_VARS.fd</nvram> <boot dev='hd'/> </os> 3. Migrate the ovmf domain. Step: # virsh migrate ovmf qemu+ssh://dst/system --live --verbose ...... Migration: [100 %] Result: Migrate successfully and the guest will run in dst host.
