virt-manager is a popular GUI-frontend for libvirt, allowing users to create and manage guest virtual machines on libvirt-supported hypervisors such as QEMU/KVM or Xen. virt-manager can control a host-local hypervisor as well as remote host's hypervisor (over SSH), giving users a location-transparent management interface for virtual machines. For remote desktop access on guest operating systems, virt-manager offers integrated remote desktop sessions via VNC and Spice.
While virt-manager is available in the base repositories of any Red Hat based distributions, the pre-built virt-manager tends to fall behind the latest release available from the official website. For example, CentOS 7 and Fedora 22 offer virt-manager version 1.2.1, while the latest virt-manager release is already version 1.3.2, as of this writing.
If you want to try out the latest features of virt-manager, you can download its source and build it yourself. Here is how to compile virt-manager on CentOS, Fedora or RHEL. If you want to build virt-manager on Debian based system, refer to this tutorial instead.
Note that since the latest virt-manager relies on GTK3, you cannot install it on CentOS/RHEL 6 or earlier.
Before you start, you need to uninstall the existing virt-manager if you have already installed it from your distro's repositories.
$ sudo yum remove virt-manager
Here we are going to build virt-manager's RPM packages from its latest source code, and install the RPMs.
First, set up the build environment, and generate virt-manager's RPM packages as follows. On Fedora, you can replace
dnf if you prefer.
$ sudo yum install rpm-build intltool $ curl -O https://fedorahosted.org/released/virt-manager/virt-manager-1.3.2.tar.gz $ tar -xf virt-manager-1.3.2.tar.gz $ cd virt-manager-1.3.2 $ python setup.py rpm
After successful build, the RPM packages will be found in
~/rpmbuild/RPMS/noarch. Go to this directory.
$ cd ~/rpmbuild/RPMS/noarch
You will find two RPM packages for virt-manager:
virt-manager-common-XXX.rpm first, and then install
$ sudo yum install virt-manager-common-1.3.2-1.NNNNNNN.noarch.rpm $ sudo yum install virt-manager-1.3.2-1.NNNNNNN.noarch.rpm
At this point you should be able to launch virt-manager.
