I just hit the abort case, narrowing it down to the /i386/migration/multifd/tcp/zlib case, which can hit this without any other tests being run: $ QTEST_QEMU_BINARY=./qemu-system-i386 ./tests/qtest/migration-test -tap -k -p /i386/migration/multifd/tcp/zlib # random seed: R02S37eab07b59417f6cd7e26d94df0d3908 # Start of i386 tests # Start of migration tests # Start of multifd tests # Start of tcp tests # starting QEMU: exec ./qemu-system-i386 -qtest unix:/tmp/qtest-782502.sock -qtest-log /dev/null -chardev socket,path=/tmp/qtest-782502.qmp,id=char0 -mon chardev=char0,mode=control -display none -accel kvm -accel tcg -name source,debug-threads=on -m 150M -serial file:/tmp/migration-test-H8Ggsm/src_serial -drive file=/tmp/migration-test-H8Ggsm/bootsect,format=raw -accel qtest # starting QEMU: exec ./qemu-system-i386 -qtest unix:/tmp/qtest-782502.sock -qtest-log /dev/null -chardev socket,path=/tmp/qtest-782502.qmp,id=char0 -mon chardev=char0,mode=control -display none -accel kvm -accel tcg -name target,debug-threads=on -m 150M -serial file:/tmp/migration-test-H8Ggsm/dest_serial -incoming defer -drive file=/tmp/migration-test-H8Ggsm/bootsect,format=raw -accel qtest Memory content inconsistency at 5f76000 first_byte = 2 last_byte = 1 current = 2 hit_edge = 1 Memory content inconsistency at 5f77000 first_byte = 2 last_byte = 1 current = 2 hit_edge = 1 Memory content inconsistency at 5f78000 first_byte = 2 last_byte = 1 current = 2 hit_edge = 1 Memory content inconsistency at 5f79000 first_byte = 2 last_byte = 1 current = 2 hit_edge = 1 Memory content inconsistency at 5f7a000 first_byte = 2 last_byte = 1 current = 2 hit_edge = 1 Memory content inconsistency at 5f7b000 first_byte = 2 last_byte = 1 current = 2 hit_edge = 1 Memory content inconsistency at 5f7c000 first_byte = 2 last_byte = 1 current = 2 hit_edge = 1 Memory content inconsistency at 5f7d000 first_byte = 2 last_byte = 1 current = 2 hit_edge = 1 Memory content inconsistency at 5f7e000 first_byte = 2 last_byte = 1 current = 2 hit_edge = 1 Memory content inconsistency at 5f7f000 first_byte = 2 last_byte = 1 current = 2 hit_edge = 1 and in another 17 pages** ERROR:../../tests/qtest/migration-test.c:276:check_guests_ram: assertion failed: (bad == 0) Bail out!
