What am I doing wrong with the virsh attach-device command or XML?
There is no support for hotplug of any character device (that covers serial, parallel, console, channnel elements in the XML)
Although that's about to change in libvirt 1.1.1: https://www.redhat.com/archives/libvir-list/2013-July/msg00125.html
Yes & no. Yes, libvirt will support hotplug, but that's only actually going to work for devices which are PCI based. eg virtio-serial and virtio-console. You can't hotplug <serial> or <paralle> devices which use the ISA bus, which is what Chris was trying todo here.
But that's just a QEMU limitation. If QEMU learns to hotplug a device onto ISA bus, libvirt will allow it.
Did real ISA buses ever support hotplug ? I thought hotplug only came along when PCI buses arrived. I'm rather doubting anyone is going to do work for ISA device hotplug in QEMU Daniel -- |: http://berrange.com -o- http://www.flickr.com/photos/dberrange/ :| |: http://libvirt.org -o- http://virt-manager.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: http://entangle-photo.org -o- http://live.gnome.org/gtk-vnc :|
