- + + + QEMU: Use adaptive timeout for connecting to monitor + + + When starting qemu, libvirt waits for qemu to create the monitor + socket which libvirt connects to. Historically, there was sharp 30 + second 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. + +
