    v2 v3  
    11In the VirtualBox forums, this problem has been reported by at least 8 users in the last weeks and months. I've analyzed those cases and from my POV the following conditions apply: 
    22 
    3 1. The host CPU is always a '''10th/11th generation Intel CPU''', so far i7-1065G7, i5-1135G7 or i5-1185G7. Using older Intel CPUs or AMD CPUs does not exhibit the problem. VirtualBox does not know up to 20 new and previously '''reserved bits in the CPUID leaf 7'''. 
     31. The host CPU is always a '''10th/11th generation Intel CPU''', so far i7-1065G7, i5-1135G7 or i5-1185G7. Using older Intel CPUs or AMD CPUs does not exhibit the problem. VirtualBox does not know up to '''20 new and previously reserved bits in the CPUID leaf 7'''. 
    44 
    552. On the host, a Linux kernel 5.8 or later is always running. Using a Linux kernel 5.4 does not exhibit the problem.
