[Qemu-devel] [PATCH V5 4/6] cpu_exec: Add sleeping algorithm

The goal is to sleep qemu whenever the guest clock is in advance compared to the host clock (we use the monotonic clocks). The amount of time to sleep is calculated in the execution loop in cpu_exec. At first, we tried to approximate at each for loop the real time elapsed while searching for a TB

Changing the ACPI table size causes migration to break, and the memory hotplug work opened our eyes on how horribly we were breaking things in 2.0 already. The ACPI table size is rounded to the next 4k, which one would think gives some headroom. In practice this is not the case, because the user

[Qemu-devel] [PATCH 0/8] block/qcow2: Improve (?) zero cluster expansion

2014-07-25 Thread Max Reitz
The main purpose of this series is to add a progress report to qemu-img amend. This is achieved by adding a callback function to bdrv_amend_options() - the reasons for this choice are explained in patch 1. While adapting qcow2's expand_zero_clusters_in_l1() accordingly, I noticed a way to

The only really time-consuming operation potentially performed by qcow2_amend_options() is zero cluster expansion when downgrading qcow2 images from compat=1.1 to compat=0.10, so report status of that operation and that operation only through the status CB. For this, count the number of L2 zero

Currently, we have a bitmap for keeping track of which clusters have been created during the zero cluster expansion process. This was necessary because we need to properly increase the refcount for shared L2 tables. However, now we can simply take the L2 refcount and use it for the cluster
