Refer to: https://www.howtogeek.com/117635/how-to-install-kvm-and-create-virtual-machines-on-ubuntu/ Summary: Determine whether your CPU support hardware virtualization egrep -c '(svm|vmx)' /proc/cpuinfo A 0 indicates that your CPU doesn't support hardware virtualization, while a 1 or more indicates that it does. You still have to enable hardware virtualization support in your computer's BIOS, even if this command returns a 1 or more. Otherwise you will get a warning later on: KVM is not available. This may mean the KVM package is not installed,  or the KVM kernel modules are not loaded.  Your virtual machines may perform poorly.

Refer: https://linux.die.net/man/3/pthread_mutex_init The pthread_mutex_destroy() function shall destroy the mutex object referenced by mutex; the mutex object becomes, in effect, uninitialized. An implementation may cause pthread_mutex_destroy() to set the object referenced by mutex to an invalid value. A destroyed mutex object can be reinitialized using pthread_mutex_init(); the results of otherwise referencing the object after it has been destroyed are undefined. What is the undefined behavior ? Let's us wirte sample codes to verify it. #include <pthread.h> #include <iostream> #include <unistd.h> using namespace std; static pthread_mutex_t foo_mutex; static void * thread1(void *arg) { while(1) { pthread_mutex_lock(&foo_mutex); cout << "thread 1 running" << endl; sleep(2); } } static void * thread2(void *arg) { while(1) { pthread_mutex_lock(&foo_mutex); cout << "thread...
