Check that your CPU supports hardware virtualization

egrep -c '(vmx|svm)' /proc/cpuinfo <===> 0 it means that your CPU doesn't support hardware virtualization. / If 1 or more it does - but you still need to make sure that virtualization is enabled in the BIOS.

egrep -c ' lm ' /proc/cpuinfo <===> 0 is printed, it means that your CPU is not 64-bit/ If 1 or higher, it is. Note: lm stands for Long Mode which equates to a 64-bit CPU.

grep -o 'vmx\|svm' /proc/cpuinfo <===> testuje zda vase CPU muze pouzivat virtualizaci - nekolikrat vypise vmx /svm kolik ma CPU vlaken

## pokud se v techto vystupech neobevi nic nebo 0 - je potreba v biosu zapnout virtualizaci VT-d (Intel Virtualization Technology ENABLED) + Inteů VT for Directed I/O (VT-d) ENABLED

LC_ALL=C lscpu | grep Virtualization <===> napise VT-x
