Installing libvirt

Only libvirt 10.0.0 and later versions support data compression and decompression using the zlib library during VM live migration.

• The feature installation involves system file modification. By default, all operations during the installation are performed by the root user. If you are a non-root user, ensure that you have corresponding permissions.
• If the libvirt of an earlier version exists, a shared library conflict may occur when the libvirt of a later version is directly installed. Therefore, uninstall the libvirt of the earlier version first.
• Configure the Yum repository in advance.

1. Install the libvirt 10.0.0 dependencies.

   1	yum install -y meson gnutls-devel yajl-devel libtirpc-devel libxslt glib2-devel libxml2-devel glusterfs-api dnsmasq git gcc patch make autoconf automake libtool

2. Perform the compilation and installation.

   1 2	meson setup build -Dsystem=true -Ddriver_qemu=enabled -Ddriver_lxc=enabled -Ddocs=disabled ninja -C build install

3. Set the library search path of the dynamic linker.
   Configure /etc/ld.so.conf and add the path for searching for the link to the compilation and installation library.

   1	/usr/local/lib64

4. Save the file and update the dynamic linker cache.
   Run the following command to update the dynamic linker cache:

   1

   ldconfig
