Хост с ESXi 5.1. На нем ВМ с гостевой ос - WinXP. Проблема в том, что машина самовыключается минут через 5 после старта. В логах машины и самого гипервизора ошибка
The VMware Tools
package is not running in this virtual machine.
The package might be necessary for the guest
operating system to run at resolutions higher
than 640x480 with 16 colors. The package
provides significant performance benefits as well.
To install it, choose VM > Install VMware Tools…
after the guest operating system starts. VMware
ESX can remind you to install the VMware Tools
package when you power on the VM. Select OK
to enable the reminder.
