From 7839ff593be03a7de3c6760e0b50c565ea751d36 Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Mon, 4 Nov 2013 14:30:48 +0100 Subject: pc: get rid of builtin pvpanic for "-M pc-1.5" This causes two slight backwards-incompatibilities between "-M pc-1.5" and 1.5's "-M pc": (1) a fw_cfg file is removed with this patch. This is only a problem if migration stops the virtual machine exactly during fw_cfg enumeration. (2) after migration, a VM created without an explicit "-device pvpanic" will stop reporting panics to management. The first problem only occurs if migration is done at a very, very early point (and I'm not sure it can happen in practice for reasonable-size VMs, since it will likely take more time to send the RAM to destination, than it will take for BIOS to scan fw_cfg). The second problem only occurs if the guest panics _and_ has a guest driver _and_ management knows to look at the crash event, so it is mostly theoretical at this point in time. Thus keep the code simple, and pretend it was never broken.
