+ qemu: Adaptive timeout for connecting to monitor
+ </summary>
+ <description>
+ When starting qemu, libvirt waits for qemu to create the monitor
+ socket which libvirt connects to. Historically, there was sharp 30
+ seconds timeout after which the qemu process was killed. This
+ approach is suboptimal as in some scenarios with huge amounts of
+ guest RAM it can take a minute or more for kernel to allocate and
+ zero out pages for qemu. The timeout is now flexible and computed by
+ libvirt at domain startup.
