Therefore, when the VM selects the latest hardware version 8 and 7, if this problem occurs, the solution disables the Non Maskable Interrupt (NMI) function. The steps are as follows: 1. Go to the command line interface of the Linux Virtual Machine and run the following command: # vi/boot/grub/menu. lst2. In the open file, change the value of nmi_watchdog from 1 to 0. If this parameter is not available, add it by yourself. Example: www.2cto.com title CentOS (2.6.18-308. el5) root (hd0, 0) kernel/vmlinuz-2.6.18-308.el5 ro root = LABEL =/nmi_watchdog = 0 rhgb quiet initrd/initrd-2.6.18-308.el5.img
