virt-clone
The virt-clone application can be used to copy one virtual machine to another. For example: virt −clone −−auto−clone −−original focal Options used: * –auto-clone: to have virt-clone come up with guest names and disk paths on its own * –original: name of the virtual machine to copy Also, use -d or –debug option to help troubleshoot problems with virt-clone. Replace focal and with appropriate virtual machine names of your case. Warning: please be aware that this is a full clone, therefore any sorts of secrets, keys and for example /etc/machine-id will be shared causing e.g. issues to security and anything that needs to identify the machine like DHCP. You most likely want to edit those afterwards and de-duplicate them as needed. Resources • See the KVM home page for more details. • For more information on libvirt see the libvirt home page • The Virtual Machine Manager site has more information on virt-manager development. LXD LXD (pronounced lex-dee) is the lightervisor, or lightweight container hypervisor. LXC (lex-see) is a program which creates and administers “containers” on a local system. It also provides an API to allow higher level managers, such as LXD, to administer containers. In a sense, one could compare LXC to QEMU, while comparing LXD to libvirt. The LXC API deals with a ‘container’. The LXD API deals with ‘remotes’, which serve images and containers. This extends the LXC functionality over the network, and allows concise management of tasks like container migration and container image publishing. LXD uses LXC under the covers for some container management tasks. However, it keeps its own container configuration information and has its own conventions, so that it is best not to use classic LXC commands by hand with LXD containers. This document will focus on how to configure and administer LXD on Ubuntu systems. Download 1.27 Mb. Do'stlaringiz bilan baham: |
