NAME<\/a> systemd-machined.service, systemd-machined \u2212 Virtual machine and container registration manager<\/p>\n systemd\u2212machined.service<\/p>\n \/usr\/lib\/systemd\/systemd\u2212machined<\/p>\n systemd\u2212machined<\/b> is a system service that keeps track of locally running virtual machines and containers.<\/p>\n systemd\u2212machined<\/b> is useful for registering and keeping track of both OS containers (containers that share the host kernel but run a full init system of their own and behave in most regards like a full virtual operating system rather than just one virtualized app) and full virtual machines (virtualized hardware running normal operating systems and possibly different kernels).<\/p>\n systemd\u2212machined<\/b> should not<\/i> be used for registering\/keeping track of application sandbox containers. A machine<\/i> in the context of systemd\u2212machined<\/b> is supposed to be an abstract term covering both OS containers and full virtual machines, but not application sandboxes.<\/p>\n Machines registered with machined are exposed in various ways in the system. For example:<\/p>\n \u2022 Tools like ps<\/b>(1) will show to which machine a specific process belongs in a column of its own, and so will gnome\u2212system\u2212monitor<\/font><\/b> [1]<\/font><\/small> or systemd-cgls<\/b>(1).<\/font><\/p>\n \u2022 systemd’s various tools (systemctl<\/b>(1), journalctl<\/b>(1), loginctl<\/b>(1), hostnamectl<\/b>(1), timedatectl<\/b>(1), localectl<\/b>(1), machinectl<\/b>(1), …) support the \u2212M<\/b> switch to operate on local containers instead of the host system.<\/font><\/p>\n \u2022 systemctl list\u2212machines<\/b> will show the system state of all local containers, connecting to the container’s init system for that.<\/font><\/p>\n \u2022 systemctl’s \u2212\u2212recursive<\/b> switch has the effect of not only showing the locally running services, but recursively showing the services of all registered containers.<\/font><\/p>\n \u2022 The machinectl<\/b> command provides access to a number of useful operations on registered containers, such as introspecting them, rebooting, shutting them down, and getting a login prompt on them.<\/font><\/p>\n \u2022 The sd-bus<\/b>(3) library exposes the sd_bus_open_system_machine<\/b>(3) call to connect to the system bus of any registered container.<\/font><\/p>\n \u2022 The nss-mymachines<\/b>(8) module makes sure all registered containers can be resolved via normal glibc gethostbyname<\/b>(3) or getaddrinfo<\/b>(3) calls.<\/font><\/p>\n See systemd-nspawn<\/b>(1) for some examples on how to run containers with OS tools.<\/font><\/p>\n If you are interested in writing a VM or container manager that makes use of machined, please have look at<\/font> Writing Virtual Machine or Container Managers<\/font><\/b> [2]<\/font><\/small> . Also see the<\/font> New Control Group Interfaces<\/font><\/b> [3]<\/font><\/small> .<\/font><\/p>\n The daemon provides both a C library interface (which is shared with systemd-logind.service<\/b>(8)) as well as a D\u2212Bus interface. The library interface may be used to introspect and watch the state of virtual machines\/containers. The bus interface provides the same but in addition may also be used to register or terminate machines. For more information please consult sd-login<\/b>(3) and org.freedesktop.machine1<\/b>(5). and org.freedesktop.LogControl1<\/b>(5)<\/font><\/p>\n A small companion daemon systemd-importd.service<\/b>(8) is also available, which implements importing, exporting, and downloading of container and VM images.<\/font><\/p>\n For each container registered with systemd\u2212machined.service that employs user namespacing, users\/groups are synthesized for the used UIDs\/GIDs. These are made available to the system using the<\/font> User\/Group Record Lookup API via Varlink<\/font><\/b> [4]<\/font><\/small> , and thus may be resolved with userdbctl<\/b>(1) or the usual glibc NSS calls.<\/font><\/p>\n systemd<\/b>(1), machinectl<\/b>(1), systemd-nspawn<\/b>(1), nss-mymachines<\/b>(8), systemd.special<\/b>(7)<\/font><\/p>\n 1.<\/font><\/p>\n<\/td>\n gnome-system-monitor<\/font><\/p>\n<\/td>\n https:\/\/help.gnome.org\/users\/gnome-system-monitor\/<\/font><\/p>\n 2.<\/font><\/p>\n<\/td>\n Writing Virtual Machine or Container Managers<\/font><\/p>\n<\/td>\n https:\/\/www.freedesktop.org\/wiki\/Software\/systemd\/writing-vm-managers<\/font><\/p>\n 3.<\/font><\/p>\n<\/td>\n New Control Group Interfaces<\/font><\/p>\n<\/td>\n https:\/\/www.freedesktop.org\/wiki\/Software\/systemd\/ControlGroupInterface\/<\/font><\/p>\n 4.<\/font><\/p>\n<\/td>\n User\/Group Record Lookup API via Varlink<\/font><\/p>\n<\/td>\n https:\/\/systemd.io\/USER_GROUP_API<\/font><\/p>\n systemd-machined.service, systemd-machined \u2212 Virtual machine and container registration manager <\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[2],"tags":[5,52,4,956],"class_list":["post-3863","post","type-post","status-publish","format-standard","hentry","category-8-administracion-del-sistema","tag-5","tag-administracion","tag-man8","tag-systemd-machined"],"gutentor_comment":0,"_links":{"self":[{"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/posts\/3863","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/comments?post=3863"}],"version-history":[{"count":0,"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/posts\/3863\/revisions"}],"wp:attachment":[{"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/media?parent=3863"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/categories?post=3863"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/tags?post=3863"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
