The theory includes discussions about types of hypervisors (first, second, not the first anymore but not yet the second, or not a hypervisor at all, and so on), and their impact on performance. An example of such an article is \u2014 <noindex><a rel=\"nofollow\" href=\"https:\/\/habr.com\/ru\/post\/467801\/\">here<\/a><\/noindex>, and in the article about one topic, they forgot to mention (Xen, Virtual PC), and completely overlooked (Protection ring). <\/p>\n<p>However, practice is quite far from this part of the theory and primarily requires the verification of completely different aspects.<\/p>\n<p>So, if you find yourself in a job where:<\/p>\n<ul>\n<li>there is VMware ESXi, vCenter, and many other scary terms<\/li>\n<li>there is no documentation, logins, passwords, backups, or anything at all<\/li>\n<li>you couldn't find a unique article <noindex><a rel=\"nofollow\" href=\"https:\/\/habr.com\/ru\/post\/333910\/\">Actions upon starting the job \u2014 taking over duties, updating, documenting, auditing<\/a><\/noindex><\/li>\n<\/ul>\n<p>\nThen you have just one week to prepare the work, and one weekend to check the following things regarding VMware (not considering backups, the condition of the servers, disks, and so on \u2014 as described in the recent wonderful <noindex><a rel=\"nofollow\" href=\"https:\/\/vmind.ru\/2019\/10\/11\/epic-fail-story\/\">article<\/a><\/noindex>.
