From a98e5a78153644e0f13b34c69d60b7a866c4401a Mon Sep 17 00:00:00 2001 From: Peter Krempa Date: Tue, 8 Sep 2015 15:06:26 +0200 Subject: [PATCH] qemu: migration: Relax enforcement of memory hotplug support If the current live definition does not have memory hotplug enabled, but the persistent one does libvirt would reject migration if the destination does not support memory hotplug even if the user didn't want to persist the VM at the destination and thus the XML containing the memory hotplug definition would not be used. To fix this corner case the code will check for memory hotplug in the newDef only if VIR_MIGRATE_PERSIST_DEST was used. --- src/qemu/qemu_migration.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/src/qemu/qemu_migration.c b/src/qemu/qemu_migration.c index d50d3675d7..1846239b5a 100644 --- a/src/qemu/qemu_migration.c +++ b/src/qemu/qemu_migration.c @@ -2989,7 +2989,8 @@ qemuMigrationBeginPhase(virQEMUDriverPtr driver, } if (vm->def->mem.max_memory || - (vm->newDef && + ((flags & VIR_MIGRATE_PERSIST_DEST) && + vm->newDef && vm->newDef->mem.max_memory)) cookieFlags |= QEMU_MIGRATION_COOKIE_MEMORY_HOTPLUG; -- GitLab
