If I symlink
ln -s /usr/bin/qemu-kvm /usr/libexec/qemu-kvm
then libguestfs-test-tool finishes successfully. Trying to launch instance...

Looks like it didn't help...

But that at least moved me further, so likely there are 2 bugs in one:
a) resize doesn't work
b) instance is not being laucnhed for other reason

Looks too similar to 1288352, so closing as duplicate.
