| |
− |
| |
− |
| |
− | QEMU (Quick Emulator) this does the disk format of image files.
| |
− |
| |
− |
| |
− | It offers an infrastructural server that consists of multiple hypervisor nodes
| |
− |
| |
− | that are managed from a central RHEV Manager node, on which a web user interface
| |
− |
| |
− | makes managing a complex environment easy.
| |
− |
| |
− |
| |
− | To access VMs that are offered through KVM, you use libvirtd. Libvirtd is a process
| |
− |
| |
− | that sits between the virtualization layer and the application that an administrator
| |
− |
| |
− | is using to access the VMs. Without libvirtd, you cannot manage VMs. Virtual
| |
− |
| |
− | machine management options also are configured through the libvirtd configuration
| |
− |
| |
− | file /etc/libvirt/libvirtd.conf.
| |
− |
| |
− |
| |
− | Although the method to connect remotely directly to '''libvirtd '''works well and is convenient
| |
− |
| |
− | for hypervisors that have a minimal number of software packages installed,
| |
− |
| |
− | alternatively you can use Secure Shell (SSH) from virt-manager to connect to
| |
− |
| |
− | remote libvirtd processes.
| |
− |
| |
− | If you are experiencing problems accessing VMs, libvirtd is the primary suspect,
| |
− |
| |
− | and you should at least ensure that it is running, by using the systemctl status -l
| |
− |
| |
− | libvirtd command. In Listing 10.1 , you can see how this command shows that libvirtd
| |
− |
| |
− | is running; the command also shows information about recent activity on the
| |
− |
| |
− | process .
| |
− |
| |
− |
| |
− | systemctl status -l libvirtd
| |

− | '''Making your server a KVM host.'''
| |
− |
| |
− |
| |
− | cat /proc/cpuinfo - '''vmx '''on an intel CPU, and '''svm '''on an AMD CPU.
| |
− |
| |
− |
| |
− | cat /proc/cpuinfo | egrep ‘<span style="background-color:#ffff00;">svm|vmx</span>’
| |
− |
| |
− |
| |
− | yum groupinstall “Virtualization Host â€.
| |
− |
| |
− | /var/lib/libvirt/images. - check space
| |
− |
| |
− |
| |
− | '''NOTE''' As an alternative to working with disk image files, you may prefer working
| |
− |
| |
− | with LVM logical volumes as the storage backend. This offers some advantages,
| |
− |
| |
− | such as the possibility to easily create backups by using the LVM snapshot feature.
| |
− |
| |
− | For this reason, LVM is often used as a storage backend in production KVM
| |
− |
| |
− | servers.
