[Qemu-devel] [Bug 1723161] [NEW] Migration failing in qemu-2.10.1 but working qemu-2.9.1 and earlier with same options

[William Tambe]

Public bug reported:


Qemu-2.10.1 migration failing with the following error:
Receiving block device images
qemu-system-x86_64: error while loading section id 2(block)
qemu-system-x86_64: load of migration failed: Input/output error

Migration is setup on the destination system of the migration using:
-incoming tcp:0:4444

Migration is initiated from the source using the following commands in its qemu 
monitor:
migrate -b "tcp:localhost:4444"

The command-line used in both the source and destination is:
qemu-system-x86_64 \
        -nodefaults \
        -pidfile vm0.pid \
        -enable-kvm \
        -machine q35 \
        -cpu host -smp 2 \
        -m 4096M \
        -drive if=pflash,format=raw,unit=0,file=OVMF_CODE.fd,readonly \
        -drive if=pflash,format=raw,unit=1,file=OVMF_VARS.fd \
        -drive file=${HDRIVE},format=qcow2 \
        -drive media=cdrom \
        -usb -device usb-tablet \
        -vga std -vnc :0 \
        -net nic,macaddr=${TAPMACADDR} -net 
user,net=192.168.2.0/24,dhcpstart=192.168.2.10 \
