Learn virtualization with KVM on a Linux host, install KVM, create and manage a CentOS virtual machine and its network, using VMware Workstation Player or native KVM utilities.
Explore KVM virtualization on Linux, enabling full virtualization for both Linux and Windows VMs, with steps to verify hardware virtualization, kernel type, and install KVM on CentOS 6.8.
Install and start libvirt and bridge utils to configure a bridged network for virtual machines. Use ifconfig and ifcfg to set eth0 dhcp and enable internet access.
Learn how to configure a bridged network for KVM virtualization by validating IP address, netmask, and gateway, editing /etc/network/interfaces, and creating a BR0 bridge with vi or nano.
Learn to create your first KVM virtual machine by configuring a bridge firewall exception, choosing between OS templates and ISO installations, and using the install command for Linux.
Learn to create the first virtual machine with KVM, configure bridged networking, troubleshoot common VM creation errors, and manage permissions for ISO images and libvirt directories.
Create and manage a KVM virtual machine on CentOS 6.8, configure the VM via its XML file, and install the word viewer package to access the display.
Set up a KVM environment by enabling libvirt, configuring a network bridge, and creating a VM. Learn to manage VM settings, edit files, and access via SSH or VNC.
Learn how to safely shut down a virtual machine, connect via SSH or PuTTY, and manage IPs, ports, and passwords to secure VM access.
Explore virsh commands for managing virtual machines, including watch list, start, destroy, suspend, and resume, with GUI tools like Virtual Machine Manager and bridge setup basics.
Explore virsh commands for managing KVM virtual machines, including configuring autostart with symlinks, inspecting CPU and memory allocations, and assigning CPUs to VMs for better performance.
Learn to pin vCPUs and configure CPU lists for KVM VMs, resolve common CPU assignment errors, and understand RAM overcommit and memory handling with swap and disk usage.
Explore how KVM virtualization manages memory with RAM and swap, including virtual RAM on disk. Learn that disk and RAM overcommitting are possible, but CPU overcommitting is not.
Use the edit command to modify a KVM virtual machine via the XML configuration, adjusting disk size, memory, and the VM name. OpenVZ reflects changes dynamically without reboot.
Learn about migration of virtual machines and backups to keep data intact in hosting environments and when servers fail.
Learn how to assign an ip address to a KVM virtual machine, compare ipv4 and ipv6 usage, and locate the vm by its mac address using virsh dumpxml and grep.
Learn how MAC addresses identify servers and how providers allocate IP blocks and MAC IPs to virtual machines, including DHCP, netmask, gateway, and the need for public IPs.
Stop and restart your KVM virtual machine to apply edits to ram, cpu, disk, and network settings, and restart libvirt services to reflect new ip configurations and restore connectivity.
Back up a running virtual machine in Linux by creating a dedicated backup directory with mkdir, securing permissions with chmod, and performing a dd backup of the VM image.
Explore using the watch command to monitor backups in real time for KVM virtualization, observe live progress, and perform simple dd backups with proper input and output file specifications.
Explore two backup methods for KVM virtual machines, including gzip-compressed backups to reduce eight gigabytes, and backing up LVM disks with img files while monitoring performance with top and watch.
Learn how to migrate a KVM virtual machine across servers, including live migration, SSH transfer, and managing storage paths, logs, and post-migration validation.
