The terminal has two kinds of character dumb terminal and

KVM-Generated virtual machines if you want to perform virtual machine console operations via the character interface, you will need to modify the relevant configuration file to implement it.

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/securet
