I was working on the Pintos project . And while I was implementing a priority donation mechanism for the proper priority scheduling , QEMU emulator just hung up (I have attached an image and the dump of the pintos is as below ) . I tried debugging and inserting printf statements , but during debugging qemu via a remote host , it again hung up as soon as it entered main . Can anybody tell me how do I troubleshoot all this . Otherwise I will have to reinstall the entire code and qemu and everything in between .
The dump from pintos:
sankalps@ubuntu:~/projects/os_projects/pintos/src$ pintos --gdb -- run alarm-zero
qemu -hda /tmp/IbpgyXzQhW.dsk -m 4 -net none -serial stdio -s -S
open /dev/kvm: No such file or directory
Could not initialize KVM, will disable KVM support
