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.

Title:
High cpu usage when guest is idle on qemu-system-i386
Status in QEMU:
Incomplete
Bug description:
When running Windows XP in qemu-system-i386, the cpu usage of QEMU is
about 100% even when the guest CPU usage is close to 2%. The host cpu
usage should be low when the guest cpu usage is low.
Command: qemu-system-i386 -hda <Windows XP HD image>
Using this command also shows around 100% host CPU usage:
qemu-system-i386 -m 700 -hda <Windows XP HD image> -usb -device usb-audio
-net nic,model=rtl8139 -net user -hdb mountable.img -soundhw pcspk
Using the Penryn CPU option also saw this problem:
qemu-system-i386 -hda <Windows XP HD image> -m 700 -cpu Penryn-v1
Using "-cpu pentium2" saw the same high host cpu usage.
My Info:

qemu-system-i386 version 5.2 (1ba089f2255bfdb071be3ce6ac6c3069e8012179)
