安装libvirt

在计算节点（x86-compute和arm-compute）执行以下操作。使用的是libvirt-5.6版本。

1. 安装edk2。
   x86-compute计算节点：

   1	yum -y install OVMF

   arm-compute计算节点：

   1	yum -y install AAVMF

2. 安装依赖包。

   1	yum -y install gnutls-devel libnl-devel libxml2-devel yajl-devel device-mapper-devel libpciaccess-devel

3. 通过源码编译安装方式安装libvirt-5.6.0。
   1. 下载libvirt源码。

      1	wget https://libvirt.org/sources/libvirt-5.6.0-1.fc30.src.rpm --no-check-certificate -O /root/libvirt-5.6.0-1.fc30.src.rpm

   2. 编译libvirt源码。

      1 2 3 4 5

      cd /root/ rpm -i libvirt-5.6.0-1.fc30.src.rpm yum -y install gcc git rpm-build iscsi-initiator-utils libxml2-devel readline-devel ncurses-devel libtasn1-devel gnutls-devel libattr-devel libblkid-devel augeas systemd-devel libpciaccess-devel yajl-devel sanlock-devel libpcap-devel libnl3-devel libselinux-devel dnsmasq radvd cyrus-sasl-devel libacl-devel parted-devel device-mapper-devel xfsprogs-devel librados2-devel librbd1-devel glusterfs-api-devel glusterfs-devel numactl-devel libcap-ng-devel fuse-devel netcf-devel libcurl-devel audit-libs-devel systemtap-sdt-devel nfs-utils dbus-devel scrub numad bash-completion qemu-img cd ~/rpmbuild/SPECS/ rpmbuild -bb libvirt.spec

      

      

      如果编译过程中提示如下信息：

      "gcc ../src/libvirt_probes.o.dtrace-temp.c" failed
      Usage /usr/bin/dtrace [--help] [-h | -G] [-C [-I<Path>]] -s File.d [-o <File>]

      请修改文件“ /bin/dtrace”，找到第308行，将keep_temps = False修改为keep_temps = True。

   3. 安装libvirt。
      • ARM计算节点：

        1	yum install -y /root/rpmbuild/RPMS/aarch64/*.rpm

      • x86计算节点：

        1	yum install -y /root/rpmbuild/RPMS/x86_64/*.rpm

   4. 重启libvirt服务。

      1	systemctl restart libvirtd

4. 检验libvirt和QEMU版本。

   1	virsh version

   返回如下信息，其中libvirt版本为5.6.0，如果安装了QEMU，则QEMU应该为4.0.0，否则为默认版本2.12.0。
