Windows XP displays black screen when smp option is used
When I use Windows XP with the -smp option, the screen goes black. The only thing I can see is a cursor. I have tried -smp 2, -smp cores=4, and -smp cores=2.
My info:
Host:
M1 Mac
Mac OS 11.1
QEMU 5.2 at cf7ca7d5b9faca13f1f8e3ea92cfb2f741eb0c0e.
Guest:
32-bit Windows XP SP3 build 2600.
Command line to reproduce this issue:
qemu-system-i386 -m 700 -hda <Windows XP HD image file> -smp 2
Last commit tested with this problem: 1214d55d1c41fbab3a9973a05085b8760647e411
I restarted QEMU without the '-smp 2' option and Windows XP started working again. The only problem is the host CPU usage will stay at 100% even with the guest CPU load being close to 0%. The only way to fix this problem that I know currently is to reinstall Windows XP.
To fix this problem open Windows XP's System Restore and restore from a point before using the smp option.
The QEMU project is currently moving its bug tracking to another system.
For this we need to know which bugs are still valid and which could be
closed already. Thus we are setting the bug state to "Incomplete" now.
If the bug has already been fixed in the latest upstream version of QEMU,
then please close this ticket as "Fix released".
If it is not fixed yet and you think that this bug report here is still
valid, then you have two options:
1) If you already have an account on gitlab.com, please open a new ticket
for this problem in our new tracker here:
https://gitlab.com/qemu-project/qemu/-/issues
and then close this ticket here on Launchpad (or let it expire auto-
matically after 60 days). Please mention the URL of this bug ticket on
Launchpad in the new ticket on GitLab.
2) If you don't have an account on gitlab.com and don't intend to get
one, but still would like to keep this ticket opened, then please switch
the state back to "New" or "Confirmed" within the next 60 days (other-
wise it will get closed as "Expired"). We will then eventually migrate
the ticket automatically to the new system (but you won't be the reporter
of the bug in the new system and thus you won't get notified on changes
anymore).
Thank you and sorry for the inconvenience.
[Expired for QEMU because there has been no activity for 60 days.]
