[Qemu-devel] vhost-user-test failure

[Eduardo Habkost]

Hi,

I hit a weird vhost-user-test failure on travis-ci recently, on a
branch where I didn't touch any vhost-related code. From a quick
look at the code, it looks like the vhost-user code is unhappy to
see a disconnected socket.

I wasn't able to reproduce it. It seems to be a hard to reproduce
race between vhost-user code and socket reconnection.

The failure can be seen at:

https://travis-ci.org/ehabkost/qemu-hacks/jobs/162077239

Error output:
