Commit96edd61dcf("xen/balloon: don't online new memory initially") introduced a regression when booting a HVM domain with memory less than mem-max: instead of ballooning down immediately the system would try to use the memory up to mem-max resulting in Xen crashing the domain. For HVM domains the current size will be reflected in Xenstore node memory/static-max instead of memory/target. Additionally we have to trigger the ballooning process at once.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
