From efe6c8021146d046846ead5b5efc9828d97c1ceb Mon Sep 17 00:00:00 2001 From: Christophe Fergeau Date: Thu, 12 Jul 2012 13:52:36 +0200 Subject: [PATCH] Fix daemon auto-spawning Commit 32a9aac switched libvirt to use the XDG base directories to locate most of its data/config. In particular, the per-user socket for qemu:///session is now stored in the XDG runtime directory. This directory is located by looking at the XDG_RUNTIME_DIR environment variable, with a fallback to ~/.cache/libvirt if this variable is not set. When the daemon is autospawned because a client application wants to use qemu:///session, the daemon is ran in a clean environment which does not contain XDG_RUNTIME_DIR. It will create its socket in ~/.cache/libvirt. If the client application has XDG_RUNTIME_DIR set, it will not look for the socket in the fallback place, and will fail to connect to the autospawned daemon. This patch adds XDG_RUNTIME_DIR to the daemon environment before auto-starting it. I've done this in virNetSocketForkDaemon rather than in virCommandAddEnvPassCommon as I wasn't sure we want to pass these variables to other commands libvirt spawns. XDG_CACHE_HOME and XDG_CONFIG_HOME are also added to the daemon env as it makes use of those as well. --- src/rpc/virnetsocket.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/src/rpc/virnetsocket.c b/src/rpc/virnetsocket.c index 0b32ffe..08dfbb0 100644 --- a/src/rpc/virnetsocket.c +++ b/src/rpc/virnetsocket.c @@ -97,6 +97,9 @@ static int virNetSocketForkDaemon(const char *binary) NULL); virCommandAddEnvPassCommon(cmd); + virCommandAddEnvPass(cmd, "XDG_CACHE_HOME"); + virCommandAddEnvPass(cmd, "XDG_CONFIG_HOME"); + virCommandAddEnvPass(cmd, "XDG_RUNTIME_DIR"); virCommandClearCaps(cmd); virCommandDaemonize(cmd); ret = virCommandRun(cmd, NULL); -- 1.7.10.4
