Hi Fi,

cmdline: console=hvc0 systemd.wants=getty at hvc0

Connect via virt-manager - View / Text Consoles / Text Console no.:

Fedora 24 (Rawhide)

It obviously works.


Connect via virsh:

# virsh console <domain> console1
Connected to domain <domain>
Escape character is ^]
error: operation failed: Active console session exists for this domain

# virsh console --devname console1 <domain>
Connected to domain <domain>
Escape character is ^]
error: operation failed: Active console session exists for this domain

Obviously does not work.

Is it possible to connect hvc via virsh, if domain/guest is started with the virt-manager?
Is it possible at all, to connect hypervisor virtual console via virsh?
