Description

Lguest enables the operation of several instances of a 32-bit kernel simultaneously; by using the command modprobe lg, you can initiate it by running Documentation/lguest/lguest to establish a new guest. I encourage you to experiment with it as lguest is exceedingly straightforward to set up. Its utility is significant: I can boot kernels for testing purposes in less than a second, which is approximately ten times quicker than standard qemu and a hundred times faster than a traditional boot process. Moreover, since it employs a pty for the console, you're able to perform actions such as piping the output through grep. Lguest comprises a comprehensive kernel patch, which includes the launcher and is available in versions 2.6.23-git13 and later. The primary goal of lguest is to keep the guest isolated, preventing it from accessing the host directly, aside from virtual devices provided by the host, even if the guest is acting maliciously. Nevertheless, a potentially harmful guest kernel has the capability to pin host memory, limited to the volume allocated to the guest. While most images are configured to create virtual consoles like (/dev/tty0, etc.), the console for lguest is designated as /dev/hvc0, which adds a layer of distinction to its functionality. Additionally, this makes lguest a practical tool for developers who want to test kernel changes in a rapid and efficient manner without the overhead of a full virtualization solution.

Yandex Cloud Backup provides a solution for safeguarding application data while ensuring its reliability through the use of the Cloud Backup agent installed in the guest operating system. Users can retrieve specific files from backups and place them in the correct directory of the current version of the virtual machine. Additionally, it is possible to establish backup policies for virtual machines across the entire cloud via the console, and these policies can be applied during the virtual machine configuration process. All backup tasks are executed in the cloud environment, necessitating only the setup and application of policies to the designated virtual machines. In contrast to a simple disk snapshot, this service generates copies of all virtual machine disks, which encompasses network SSDs, HDDs, non-replicated disks, and dedicated host local disks. If reverting the current virtual machine to a prior state proves unfeasible, users have the option to restore the backup to a newly created virtual machine, thus ensuring flexibility and resilience in data management. This capability makes Yandex Cloud Backup a comprehensive tool for managing not just backups but also the overall integrity of applications running in the cloud.
