I can reproduce this:
./x86_64-softmmu/qemu-system-x86_64 -nographic -M q35 -drive
id=d,file=/home/vmimages/dummy1,if=none,readonly -device virtio-
blk,id=vb1,drive=d -drive
if=pflash,format=raw,unit=0,file=/usr/share/edk2/ovmf/OVMF_CODE.secboot.fd,readonly
-drive if=pflash,format=raw,unit=1,file=vars1.fd
to:
./x86_64-softmmu/qemu-system-x86_64 -M q35 -nographic -drive
id=d,file=/home/vmimages/dummy2,if=none,readonly -device
virtio-blk,id=vb1,drive=d -drive
if=pflash,format=raw,unit=0,file=romfile,readonly -drive
if=pflash,format=raw,unit=1,file=vars2.fd -incoming tcp::4444
then
migrate -d -b tcp:0:4444
note I copied the vars file and rom file separately so it's not a
locking issue
