Commit Message

wangyanan (Y) Sept. 10, 2021, 7:30 a.m. UTC
Since commit 80d7835749 (qemu-options: rewrite help for -smp options),
the preference of sockets/cores in -smp parsing is considered liable
to change, and actually we are going to change it in a coming commit.
So it'll be more stable to use detailed -smp CLIs in the testcases
that have strong dependency on the parsing results.

Currently, test_def_cpu_split use "-smp 8" and will get 8 CPU sockets
based on current parsing rule. But if we change to prefer cores over
sockets we will get one CPU socket will 8 cores, and this testcase
will not get expected numa set by default on x86_64 (Ok on aarch64).

So now explicitly use "-smp 8,sockets=8" to avoid affect from parsing
logic change.
