The current timeout is set to only three seconds - and considering that vring_wait_reply() or rather get_second() is not doing any rounding, the real timeout is likely rather 2 seconds in most cases. When the host is really badly loaded, it's possible that we hit this timeout by mistake; it's even more likely if we run the guest in TCG mode instead of KVM. So let's increase the timeout to 30 seconds instead to ease this situation (30 seconds is also the timeout that is used by the Linux SCSI subsystem for example, so this seems to be a sane value for block IO timeout).
