Test 11_create_concurrent_pos of xm-test suite only creates
33 domains and then gets: Cannot allocate memory. The host has c/s 15464
of 3.1.1 and it has plenty of memory – 256GB.
Xend log shows:

Error: (12, 'Cannot allocate memory')
Xm-test default for domain size was 64M; the README
recommends increasing the domain size if there are memory errors, so I tried
128M, 256M and 512M. When I reboot the host with 192gb, leaving the
domain memory size as 512M, the test does not fail.
Any ideas why adding the extra host memory causes the test
to fail?
