Series [PULL,01/76] vhost-user-test: use g_cond_broadcast | expand

Commit Message

Paolo Bonzini Feb. 5, 2019, 6:14 p.m. UTC 
The virt machine cannot run the vhost-user qtests because they hardcode
the presence of memory at address 0.  Report the tests as a skip so that
they can be converted to use qgraph.
