I couldn't re-produce this error locally for both docker-test-quick@centos7
and this docker test. And I can't see any reason for this error to occur since
VHOST_MEMORY_MAX_NREGIONS is defined in contrib/libvhost-user/libvhost-user.h
which has been included by util/vhost-user-server.h.
Please see the recent change in commit
b650d5f4b1cd3f9f8c4fdb319838c5c1e0695e41 ("Lift max ram slots limit in
libvhost-user").
The error can be solved by replacing VHOST_MEMORY_MAX_NREGIONS with
VHOST_MEMORY_BASELINE_NREGIONS in util/vhost-user-server.c.
