Solve the problem that the virsh console cannot connect to the KVM virtual machine.

As shown in this case, the link to the KVM virtual machine through the virsh console is stuck on this interface, and no operations can be performed.

You can solve this problem by using the following methods.

1. Modify/etc/securetty and add ttyS0 to the end.

Echo ttyS0>/etc/securetty

2. Modify/etc/inittab to add S0: 12345: respawn:/sbin/agetty/ttyS0 115200.

Echo "S0: 12345: respawn:/sbin/agetty/ttyS0 115200">/etc/inittab

3. Modify/etc/grub. conf, as shown in, add console = ttyS0 at the end of the kernel line

Try again after restart. The connection is normal.
