vzreboot

vzreboot is used to update Parallels Cloud Server without rebooting the physical server.

Syntax

vzreboot [ kernel_version ]

When run without options, the command checks the GRUB configuration file to determine the default kernel, loads this kernel into memory, and then boots the new kernel. You can also specify the kernel version manually (e.g., vzreboot 2.6.32-042stab054.2 ) to load and boot to the indicated kernel instead of the one set as default in the GRUB configuration file.
