下文提及内容均是基于源码编译升级。已经安装了qemu,libvirt和virt-manager
qemu升级：
yum -y install gcc gcc-c++ automake libtool zlib-devel glib2-devel bzip2-devel libuuid-devel spice-protocol spice-server-devel usbredir-devel libaio-devel ceph-devel pixman-devel
yum install libaio-devel #和lvm做后端存储有关
#关于spice
wget https://www.spice-space.org/download/releases/spice-protocol-0.12.9.tar.bz2
tar -jxvf spice-protocol-0.12.9.tar.bz2
cd spice-protocol-0.12.9
./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var --libdir=/usr/lib64
make -j30
make install
yum install celt051-devel
wget https://www.spice-space.org/download/releases/spice-0.14.0.tar.bz2
tar -jxvf spice-0.14.0.tar.bz2
cd spice-0.14.0
./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var --libdir=/usr/lib64
make -j30
make install
# root用户下 # wget https://download.qemu.org/qemu-2.10.2.tar.xz xz -d qemu-2.10.2.tar.xz tar -xvf qemu-2.10.2.tar cd qemu-2.10.2 ./configure --prefix=/usr --localstatedir=/var --sysconfdir=/etc --enable-kvm --enable-rbd --target-list=aarch64-softmmu --enable-spice # 使用ceph时enable-rdb make -j30 make install
编译完成之后 做链接, 替换qemu-kvm:
ln -s /usr/bin/qemu-system-aarch64 /usr/bin/qemu-kvm
ln -s /usr/bin/qemu-system-aarch64 /usr/libexec/qemu-kvm
libvirt升级：
yum install gcc libnl-devel libxml2-devel yajl-devel device-mapper-devel libpciaccess-devel libnl3-devel netcf-devel numactl-devel
wget https://libvirt.org/sources/libvirt-4.0.0.tar.xz xz -d libvirt-4.0.0.tar.xz tar -xvf libvirt-4.0.0.tar cd libvirt-4.0.0 ./configure --prefix=/usr --localstatedir=/var --sysconfdir=/etc --with-numactl make make install
ldconfig #更新动态链接库
重启libvirtd，执行virsh version验证，如下：
root@ubuntu:/usr/lib/x86_64-linux-gnu# virsh version Compiled against library: libvirt 4.0.0 Using library: libvirt 4.0.0 Using API: QEMU 4.0.0 Running hypervisor: QEMU 2.10.0
virt-manager不需升级，直接使用即可。如果使用apt install virt-manager升级会造成libvirt被重新安装回旧版本。
VM Fireware替换：
安装edk2包：
# 这个edk2包可以启动cirros yum install http://rpmfind.net/linux/fedora-secondary/releases/27/Everything/aarch64/os/Packages/e/edk2-aarch64-20170209git296153c5-5.fc27.noarch.rpm
# 比较新的edk2包，不支持cirros yum install https://www.kraxel.org/repos/jenkins/edk2/edk2.git-aarch64-0-20180612.154.gc25d390552.noarch.rpm
替换AAVMF文件：
rm /usr/share/AAVMF/* -rf ln /usr/share/edk2/aarch64/QEMU_EFI-pflash.raw /usr/share/AAVMF/AAVMF_CODE.fd ln /usr/share/edk2/aarch64/vars-template-pflash.raw /usr/share/AAVMF/AAVMF_VARS.fd
即可完成，注意edk2有时是edk2.git
