hej hej,
i've a question about the virtual time implementation in kvm/qemu.
with the monitor commands stop / continue you can stop and start the
guest system, but the system clock is still running.
i\ve done the following experiment:
* start the guest system
* display the system time by running 'date' in the guest system
* stop via the monitor
* way for a minute or so
* continue via the monitor
* display the system time with 'date' in the guest system
result: the system clock of the guest system was running the whole time
for what i need it:
i'm working on a simulation of a wireless network with at least 100
nodes (routers). each node should be represented by a kvm instance
with a minimal os and some daemons (mainyl routing deamons). because
the system gets overloaded some processes (kvm instances) are starving
and the simulation is not working any more. so i would like to stop
and start the guest system by the simulation program to keep them in
order. therefore stopping and starting must be fast and it must be a
full stop.
if i have to write a patch for qemu, that's fine for me. i just have
no idea which parts of the source-code i have to change.
thx for your help,
roman
