[libvirt] [PATCH 2/2] qemu_conf: Allow overriding of path for managed-save

This patch allows users to set different path for managed-save images than under /var/lib/libvirt/qemu/save; Some sysadmins do have small / and thus /var but don't want to compile libvirt on their own just to override this path. --- src/qemu/qemu.conf | 7 +++++++ src/qemu/qemu_conf.c | 15 ++++++++++++--- 2 files changed, 19 insertions(+), 3 deletions(-) diff --git a/src/qemu/qemu.conf b/src/qemu/qemu.conf index 95428c1..ae634ef 100644 --- a/src/qemu/qemu.conf +++ b/src/qemu/qemu.conf @@ -350,3 +350,10 @@ # #keepalive_interval = 5 #keepalive_count = 5 + +################################################################### +# Configurable paths: +# This allows user to override some paths libvirt uses for storing +# files like managed-save, etc. +# +# managed_save_dir = "/var/lib/libvirt/qemu/save/" diff --git a/src/qemu/qemu_conf.c b/src/qemu/qemu_conf.c index a22f3c7..0b06ef2 100644 --- a/src/qemu/qemu_conf.c +++ b/src/qemu/qemu_conf.c @@ -505,9 +505,18 @@ int qemudLoadDriverConfig(struct qemud_driver *driver, if (virAsprintf(&driver->cacheDir, "%s/cache/libvirt/qemu", LOCALSTATEDIR) == -1) goto out_of_memory; - if (virAsprintf(&driver->saveDir, - "%s/lib/libvirt/qemu/save", LOCALSTATEDIR) == -1) - goto out_of_memory; + + p = virConfGetValue (conf, "managed_save_dir"); + CHECK_TYPE ("managed_save_dir", VIR_CONF_STRING); + if (p && p->str) { + if (!(driver->saveDir = strdup(p->str))) + goto out_of_memory; + } else { + if (virAsprintf(&driver->saveDir, + "%s/lib/libvirt/qemu/save", LOCALSTATEDIR) == -1) + goto out_of_memory; + } + if (virAsprintf(&driver->snapshotDir, "%s/lib/libvirt/qemu/snapshot", LOCALSTATEDIR) == -1) goto out_of_memory; -- 1.7.3.4
