Re: [Libvir] PATCH: Fix compat for Xen 3.2.0

Xen 3.2.0 removed the sockets_per_node field from the nodeinfo data returned by XenD. I previously add compat for this, but got it in the wrong place so it would most likely end up in a divide-by-zero error. This patch re-arranges it to be correct. diff -rup libvirt-0.4.0.orig/src/xend_internal.c libvirt-0.4.0.new/src/xend_internal.c --- libvirt-0.4.0.orig/src/xend_internal.c 2007-12-17 18:05:27.000000000 -0500 +++ libvirt-0.4.0.new/src/xend_internal.c 2008-01-18 21:13:30.000000000 -0500 @@ -1907,6 +1907,9 @@ sexpr_to_xend_node_info(struct sexpr *ro info->mhz = sexpr_int(root, "node/cpu_mhz"); info->nodes = sexpr_int(root, "node/nr_nodes"); info->sockets = sexpr_int(root, "node/sockets_per_node"); + info->cores = sexpr_int(root, "node/cores_per_socket"); + info->threads = sexpr_int(root, "node/threads_per_core"); + /* Xen 3.2.0 replaces sockets_per_node with 'nr_cpus'. * Old Xen calculated sockets_per_node using its internal * nr_cpus / (nodes*cores*threads), so fake it ourselves @@ -1921,8 +1924,6 @@ sexpr_to_xend_node_info(struct sexpr *ro if (info->sockets == 0) info->sockets = 1; } - info->cores = sexpr_int(root, "node/cores_per_socket"); - info->threads = sexpr_int(root, "node/threads_per_core"); return (0); }
