Cockpit 250 now supports accepting live kernel patches and migrating virtual machines

Cockpit has a "limited access" mode, with reduced privileges, which requires administration rights. If someone is stuck in "restricted access" mode without knowing how to exit, it seems that Cockpit cannot perform tasks that it should be able to do. To make it more obvious how to switch modes, Cockpit now has several "attractive" changes on each page of the Cockpit and in the overview page alert.

All of the above changes only affect "limited access" mode. The normal mode of administration looks the same as before.

The menu on the top right is now called "Session" instead of displaying a user icon. This clarifies that the settings in that menu also apply to remote hosts, which eventually run as a different user.

Some operating systems (Red Hat Enterprise Linux for now) support live kernel patches ("kpatch"). The software updates page shows if kpatch is supported and if there are active patches. You can enable patches for the currently running kernel and subscribe to patches for future kernel versions.

The Cars page can now migrate a virtual machine to a different machine. Supports real-time and temporary migration. Typically, VM storage is shared storage, which avoids the need to copy data to the computer remotely and makes the migration process much faster and more robust. Because it is not possible to automatically detect if the storage is shared, the user must explicitly say whether the storage should be copied.
