I've also experienced a bunch of similar failures with travis, like:

https://travis-ci.org/gkurz/qemu/jobs/466994463

The KVM error messages aren't directly related to the failure IMHO.

In both cases, the cause of the failure seems to be:

No output has been received in the last XXm0s, this potentially indicates a
stalled build or something wrong with the build itself.
Check the details on how to adjust your build configuration on:
https://docs.travis-ci.com/user/common-build-problems/#Build-times-out-because-no-output-was-received
The build has been terminated

and the last GTESTER line is for tests/test-qht-par:

https://travis-ci.org/aik/qemu/jobs/470796318#L8219

https://travis-ci.org/gkurz/qemu/jobs/466994463#L4454

This has been recently discussed on qemu-devel:

https://lists.gnu.org/archive/html/qemu-devel/2018-12/msg01638.html

But I haven't seen anything come out that yet.
