Re: [libvirt] [PATCH 1/2] support compression at virsh dump

>From 4f74c4a69785432258ad5ea5e695d1b94aaa5b30 Mon Sep 17 00:00:00 2001 From: KAMEZAWA Hiroyuki <kamezawa.hiroyu(a)jp.fujitsu.com&gt; Date: Thu, 28 Oct 2010 16:31:46 +0900 Subject: [PATCH 1/2] add compression support for "virsh dump" Add dump_image_format[] to qemu.conf and support compressed dump at virsh dump. coredump compression is important for saving disk space in an environment where multiple guests run. In general, "disk space for dump" is specially allocated and will be a dead space in the system. It's used only at emergency. So, it's better to have both of save_image_format and dump_image_format. "save" is done in scheduled manner with enough calculated disk space for it. This code reuses some of save_image_format[] and supports the same format. Changelog: - modified libvirtd_qemu.aug - modified test_libvirtd_qemu.aug - fixed error handling of qemudSaveCompressionTypeFromString() --- src/qemu/libvirtd_qemu.aug | 1 + src/qemu/qemu.conf | 4 +++ src/qemu/qemu_conf.c | 11 ++++++++++ src/qemu/qemu_conf.h | 1 + src/qemu/qemu_driver.c | 41 ++++++++++++++++++++++++++++++++------ src/qemu/test_libvirtd_qemu.aug | 2 + 6 files changed, 53 insertions(+), 7 deletions(-)
