  • Virtuozzo 6.0


The virtual machine and hardware node CPU usage is very high, the usage in VM picks to almost 100% regularly.

The CPU used on the Parallels Cloud Server node does not support Intel-VTx with EPT.


Without Extended Page Tables all Guest's (virtual machine's OS) page faults are processed by the Hypervisor.


Increasing amount of memory allocated to the virtual machine can help, but the performance will not improve much unless a CPU with EPT support is used on the node
