Failed to allocate 20000000 memory The emulator seems to hang/get stuck during booting from the CD taking out --enable-hax allows it to boot. Which version were you exactly using? Can you still reproduce the problem with the latest version of QEMU? [Expired for QEMU because there has been no activity for 60 days.]
