Hi all, This sounds very odd. I ran the following this morning: build/ARM/gem5.opt configs/example/fs.py
This gives me a login prompt within roughly 80 seconds on a not-so-impressive workstation. Note that this is running on the atomic CPU, and using all the default options.

I am doing it for ARM. build/ARM/gem5.opt configs/example/fs.py --disk-image=/home/junaid/gem5/disks/arm-ubuntu-natty-headless.img Is there any detailed CPU model in this? Ruslan, Are you also building the system for ARM?

The gem5.opt boots in 90 minuts on my dual core machine. while gem5.fast takes 60 minutes. Why is this time so long as compared to other emulators such as Qemu.

Nevertheless, those times seem very long, unless you are using the detailed CPU model or something.

I have the same problem - FreeBSD guest boot time is about 90 minutes, while Linux kernel provided by gem5 community booting faster - 10 minutes.
