[Qemu-discuss] How to let kvm not reset the Qemu guest after long debug break

[Shi, Steven]

Hello,
I meet a guest platform reset problem with --enable-kvm when I debug the Qemu 
HW model code, and I hope to know how to let kvm not reset the Qemu guest when 
I debug.
The problem is if I set breakpoints on some HW device code, e.g. dev-storage.c, 
to pause the Qemu execution and do some step executions, then later,  I resume 
the Qemu to hope Qemu guest can continue to run. But I found the Qemu guest CPU 
will reset like a new power on. I guess it is because my debug break is too 
long and let the kvm time out. This guest reset problem does not happen if I 
remove the --enable-kvm and use the software emulation, but the performance 
became very bad.
Please advise how could I better debug Qemu HW model code with kvm enabled.

Thanks!
