From: Olaf Hering Date: Mon, 4 Jan 2021 20:58:42 +0200 Subject: libxc sr number of iterations Reduce default value of --max_iters from 5 to 1. The workload within domU will continue to produce dirty pages. It is unreasonable to expect any slowdown during migration. Now there is one initial copy of all memory, one instead of five iterations for dirty memory, and a final copy iteration prior move. --- tools/libs/light/libxl_internal.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) --- a/tools/libs/light/libxl_internal.h +++ b/tools/libs/light/libxl_internal.h @@ -125,7 +125,7 @@ #define DOMID_XS_PATH "domid" #define PVSHIM_BASENAME "xen-shim" #define PVSHIM_CMDLINE "pv-shim console=xen,pv" -#define LIBXL_XGS_POLICY_MAX_ITERATIONS 5 +#define LIBXL_XGS_POLICY_MAX_ITERATIONS 1 #define LIBXL_XGS_POLICY_TARGET_DIRTY_COUNT 50 #define DIV_ROUNDUP(n, d) (((n) + (d) - 1) / (d))
