Connect via virt-manager - View / Text Consoles / Text Console 1: Fedora 24 (Rawhide) Kernel 4.3.0-0.rc3.git2.4.fc24.x86_64 on an x86_64 (hvc0) localhost login: root # tty /dev/hvc0 # cat /proc/cmdline BOOT_IMAGE=vmlinuz0 initrd=initrd0.img root=live:CDLABEL=Rawhide-Xfce-Live-1001 rootfstype=auto ro rd.live.image console=hvc0 systemd.wants=getty@hvc0 console=hvc1 systemd.wants=getty@hvc1 Connect via virsh to "Text Console 2": # virsh console <domain> console0 Connected to domain <domain> Escape character is ^] error: operation failed: Active console session exists for this domain - This console is obviously busy! # virsh console <domain> console1 Connected to domain <domain> Escape character is ^] Fedora 24 (Rawhide) Kernel 4.3.0-0.rc3.git2.4.fc24.x86_64 on an x86_64 (hvc1) localhost login: root Last login: Fri Oct 2 18:41:46 on hvc0 # tty /dev/hvc1 Conclusion: It is necessary to shutdown domain/guest and disconnect from hypervisor, after the connection established via virt-manager, to free up a slot for next connection, via virsh. And vice versa. Even better is if defined more "Text Consoles" i.e. hypervisor virtual consoles, as shown here. _______________________________________________ libvirt-users mailing list libvirt-users@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvirt-users
