The Cfx.re Platform Server requires support for x86-64-v2 instructions (such as POPCNT).
Your current CPU (“Common KVM processor”) does not appear to support this. Supported CPUs include most CPUs from around 2010 or newer.
Exiting.

Can you help me ?

Fix your KVM configuration to use the right CPU model.
