How do I recover the console of the first guest when itself is connected to a guest of which it is the host?
Host1:~$ virsh console Guest1
...
Connected to domain 'Guest1'
Escape character is ^] (Ctrl + ])
Guest2 login:
Guest1 has been connected to Guest2 using the virsh console Guest2 command.
Guest2 runs on Guest1 with the same KVM and LIBVIRT packages as Guest1 does on Host1.
I do not want to reboot any machine.
I possess the credentials of all machines.
Reading the documentation for virsh (see man virsh) we find,
-e,--escape stringSet alternative escape sequence forconsolecommand. By default,telnet's^]is used. Allowed characters when using hat notation are: alphabetic character,@,[,],^,_.
Using this information you can use ^] to disconnect from the first session, change the escape character to something like ^a, reconnect, and then use ^] as a pass-through this time to disconnect the second session:
virsh -e '^a' console guest1
