Android emulator hangs on start-up

view story

http://stackoverflow.com – I'm trying to use android emulator on a Linux 64 ( kernel 3.10.0 ) with kvm Android emulator version 22.3.0 (build_id OPENMASTER-887826) The problem is that most of the time the emulator hangs on startup. The screen is black (don't reach the google logo to appear) and the CPU of my PC show no activity. I have waited many minutes but nothing happen. I say "most of the times" because if I reboot the PC and restart the emulator sometimes it start well (same command line options), and android boot very fast in less than a minute. The command line I use for launch the emulator is: emulator -v (HowTos)
