2013-09-02pseries: Fix stalls on hypervisor virtual consoleAnton Blanchard1-0/+2
A number of users are reporting stalls when using the pseries hypervisor virtual console. A simple test case is to paste 15 or 17 characters at a time into the console. Pasting 15 characters at a time works fine but pasting 17 characters hangs for a random amount of time. Other activity (network, qemu monitor etc) unblocks it. If qemu-char tries to send more than 16 characters at once, vty_can_receive returns false. At this point we have to wait for the guest to consume that output. Everything is good so far. The problem occurs when the the guest does consume the output. We need to signal back to the qemu-char layer that we are ready for more input. Without this we block until something else kicks us (eg network activity). Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: Alexander Graf <agraf@suse.de>

Convert stderr messages calling error_get_pretty() to error_report(). Timestamp is prepended by -msg timstamp option with it. Per Markus's comment below, A conversion from fprintf() to error_report() is always an improvement, regardless of error_get_pretty(). http://marc.info/?l=qemu-devel&m=137513283408601&w=2 But, it is not reasonable to convert them at one time because fprintf() is used everwhere in qemu. So, it should be done step by step with avoiding regression.
