Restricting multiple password changes in one day prevents users from cycling through password changes just to reuse an old password, thereby enforcing stronger security practices.

The load averages (8.71, 8.24, 7.71) are well above the number of CPUs (4), showing CPU saturation. Additionally, Output 2 indicates very high CPU usage (65.88% usr, 20.54% sys) with
0% idle, confirming the system is under heavy CPU load, which explains the unresponsiveness.

CPU architecture must match because live migration requires CPU compatibility to continue running the virtual machine without errors.
Disk storage path must match so the migrated VM can access its virtual disks seamlessly on the destination host.
