From: Stefano Stabellini<address@hidden> Since CS 21994 on xen-unstable.hg and CS 466608f3a32e1f9808acdf832a5843af37e5fcec on qemu-xen-unstable.git, few changes have been introduced to the PV console xenstore protocol, as described by the document docs/misc/console.txt under xen-unstable.hg. From the Qemu point of view, very few modifications are needed to correctly support the protocol: read from xenstore the "output" node that tell us what the output of the PV console is going to be. In case the output is a tty, write to xenstore the device name. Changes in v2: - fix error paths: free malloc'ed strings and close the xenstore connection before returning; - remove useless snprintf in xenstore_store_pv_console_info if i == 0. Changes in v3: - replace xs_daemon_open/xs_daemon_close with xs_open/xs_close.
