qemu-kvm chardev pty id charserial0 Failed to create chardev

If you are trying to install a virtual machine and you get these errors:

Create virtual machine error

Create virtual machine error in console

Then you need to modify an entry in /etc/fstab and change the devpts line to this one:

devpts /dev/pts devpts gid=5,mode=620 0 0

Then run:

mount -o remount /dev/pts
