2.check dmesg in guest
# dmesg --level=err,warn 
OR
# dmesg -T -l 0,1,2,3,4 | grep .

Actual results:
After step2, found the following message: 
# dmesg --level=err,warn
[    0.161379]   #2
[    0.163582]   #3
[    0.165382]   #4

[    2.165834] sd 0:0:0:0: Power-on or device reset occurred

Expected results:
After step2, There should not have warn and fail in dmesg

Additional info:
1) boot a guest with max memory, also hit the same issue.
2) There is a similar error:
