Hi,
How can I debug the Qemu source code?
Thanks,

Hi,
I found that many Armadillo-packed programs fail to work on Qemu (but
is OK to run on KVM). Something must be wrong on the way we emulate
some instructions.
Anybody experiences this problem, and know where the issue is?
Thanks,
Jun

The LSI controller was lacking any system reset handler. This is an
attempt to fix it.

Hi,
I am trying to inject NMIs to a guest running in QEMU by using
cpu_interrupt(). I notice that QEMU slows down significantly when NMIs
are being injected.
The injected NMIs per second is around 10. QEMU is pined to one core.
A computation intensive application runs in the guest. When no NMIs

The tool can trace the functions directly without any exra options.

Regarding to the que
qemu-img rebase must always give clusters in the COW file priority over those
in the backing file. As it failed to use number of non-allocated clusters but
assumed the maximum, it was possible that allocated clusters were taken from
the backing file instead, leading to a corrupted output image.

The old test didn't consider cases in which the COW files contains some
unallocated clusters and after them allocated ones again.

Hi,
This patch series adds VirtFS to QEMU. VirtFS is code named for a 9P filesystem
server in QEMU enabling paravirtual filesystem pass-trhough between KVM host
and guest.
VirtFS is intended to offer an alternative to using NFS/CIFS to share host
filesystems on
guest and provides better perform

This adds the wr_highest_sector blockstat which implements what is generally
known as the high watermark. It is the highest offset of a sector written to
the respective BlockDriverState since it has been opened.
The query-blockstat QMP command is extended to add this value to the result,
