Commit Message

Yanan Wang Sept. 28, 2021, 3:57 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 testing if we
have strong dependency on the parsing results.

pc_dynamic_cpu_cfg currently assumes/needs that there will be 2 CPU
sockets with "-smp 2". To avoid breaking the test because of parsing
logic change, now explicitly use "-smp 2,sockets=2".
