Fedora20 compilation and installation qemu-system

1.1. All the operations for this compilation and installation are on the Fedora 20 x86-64 with the kernel version 3.14.4-200. fc1_x86 _ 64. For compilation and installation in other systems, see other articles.

2. Installation preparation:

2.1 install the dependency and compiling environment .. /Configure does not report errors when necessary dependencies are insufficient. Therefore, the dependencies I installed below are not fully installed, but can be compiled at least. Many useless packages may be installed.

　　　　

yum install automake autoconfig clang gcc gcc-c++ cdk-devel curl-devel gtk-vnc2-devel gvnc-devel novnc xen-devel SDL2-mixer-devel  bluez-libs-devel libaio-devel brlapi-devel ccompdrbd-udev gcc-objc gcc-objc++ ghc-OpenGL-devel glib-devel glusterfs glusterfs-api glusterfs-devel glusterfs-devel  gprof2dot gtk-vnc-devel  libcap-ng-devel libfdt-devel  libiscsi libiscsi-devel libmpcdec-devel libseccomp-devel libseccopm-devel libtool  libusb-devel llvm-libs  ncurses-devel nss-softokn-freebl-devel compsparse-devel spice-glib-devel spice-gtk3-devel spice-server-devel sysprof trousers trousers-static uuid-devel vhostmd xfsprogs-devel

2.2 obtain the source code:

　　　　

yum install gitgit clone git://git.kernel.org/pub/scm/virt/kvm/qemu-kvm.git qemu-kvm.git

 

3. Compile and install:

Note that-w should be added to CFLAGS, because the source code of git treats the warning as an error. I didn't find the related options in makefile, so I had to disable it.

export CFLAGS="-w -O3 -msse -msse2 -mmmx -funroll-loops -mfpmath=sse"cd qemu-kvm.git./configure --prefix=/usr/local/qemu-systemmakemake install

 

4. test and install:

Create a 16 GB qcow2 format image file, and then start a M memory dual-core virtual machine from the CentOS-6.5-x86_64-minimal.iso.

qemu-img create -f qcow2 CentOS-6.5-x64.qcow2 16G qemu-system-x86_64 --enable-kvm -m 1024 -smp 2 -boot order=cd -hda CentOS-6.5-x64.qcow2 -cdrom /home/livenux/Public/System-cd/CentOS-6.5-x86_64-minimal.iso

After the CentOS is started, we can see the installation interface of CentOS:

5. Follow-up:

In fact, at the time of writing this article, the system has been installed and has been restarted for a period of time and then crashed. We will continue to share our future experiences.
