When running all the tests with taskset -c 0-3 ./run_tests.sh on a rockpro64 (on
the Cortex-a53 cores) the its-migration test hangs. In the log file I see:
run_migration timeout -k 1s --foreground 90s /usr/bin/qemu-system-aarch64

Now migrate the VM, then press a key to continue...

If I run the test manually:
$ taskset -c 0-3 ./arm-run arm/gic.flat -smp 4 -machine gic-version=3 -append
'its-migration'
/usr/bin/qemu-system-aarch64 -nodefaults -machine virt,gic-version=host,accel=kvm

Now migrate the VM, then press a key to continue...
And the test hangs here after I press a key.
