No clue what is going on here.
I haven't touched exec migration (famous last words)

This is tested by ./tests/migration-test
It passes for me with qemu-system-x86_64 (kvm), qemu-system-i386 (kvm)
and aarch64 (tcg). What make check tests.

Dunno again.

This is something that changed on the series, so I will check with this
avocado tests. No clue why it passes with x86_64 and not with aarch64.
> not an instance of type qio-channel-rdma
Here there was an error creating the RDMA channel somehow. Somehow is
the important word on the previous sentence.

Will isolate the non RDMA changes and try to pass the RDMA ones through
avocado.
I am sorry for the noise.
Later, Juan.
