[Qemu-devel] [Bug 855633] Re: guest boots up too slowly

[Yongjie Ren]

sorry, the right command to reproduce is 'qemu-system-x86_64 -m 1024
-smp 2 -hda /root/rhel6.img'. I missed the '-hda' in the bug
description.

Title:
  guest boots up too slowly

Status in QEMU:
  New

Bug description:
  qemu.git commit: 6cc7686696f73ae87cadef4450776a488b0e0c8b
  kvm.git commit: 7f914d61cd2156e34a7852462bb4932621f33a34

  It will costs about 180 seconds to booting up a rhel6 guest. But when
  I use qemu-kvm.git with commit a040d28b, the rhel6 guest can boot up
  in about 50 seconds.  I did the comparative test in the same box and
  using the same command line to create a guest  BTW, I tested qemu-
  kvm.git not qemu.git before kernel.org was down.

  Reproduce steps:
  ----------------
  1. to create a guest: qemu-system-x86_64  -m 1024 -smp 2 /root/rhel6.img
  (It maybe cost about 180 seconds to boot up.)
