On systems with many pcpus, the sexpr returned by xend can be quite large for dom0 when it is configured to have #vcpus = #pcpus (default). E.g. on a 80 pcpu system, where dom0 had 80 vcpus, the sexpr details for dom0 was 73817 bytes! Increase maximum buffer size to 256k. --- src/xen/xend_internal.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/src/xen/xend_internal.c b/src/xen/xend_internal.c index 957cd17..1fdebe1 100644 --- a/src/xen/xend_internal.c +++ b/src/xen/xend_internal.c @@ -56,7 +56,7 @@ * The number of Xen scheduler parameters */ -#define XEND_RCV_BUF_MAX_LEN 65536 +#define XEND_RCV_BUF_MAX_LEN 262144 static int virDomainXMLDevID(virDomainPtr domain, -- 1.7.5.4 -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
