Hi Yifan. The status right now is that we are moving to ARMv6 for the performance updates as it was deemed necessary for acceptable performance. The current system seems to be somewhat unstable and relies on the timing of your host CPU amongst other things. The specific error that you're seeing I suspect is connected to using incompatible versions of the host kernel tree and the guest qemu tree. Let's make sure that these are in sync. Which branches do you use for the two repositories? The goal is to within weeks provide a full ARMv6 development environment based on an emulator (and contributions thereafter are very very welcome) and for developers with ARMv6 hardware access to develop on those. We will not spend too much time on the Goldfish platform. -Christoffer 2010/9/13 Yifan Zhang <ivan.zhang.iv at gmail.com>: > Hello everyone, > > I was trying to compile and run AndroidVirt according to the > "AndroidVirt:Guides:Development Environment" page in the project wiki.
