Commit 60f7303c151cccdbe214b9f9ac59ecaf95cbf24b introduced the error message but it's unclear whether the persistent config or the live config tripped the message. Later the LXC driver copied the same code. Separate the message which will also clarify the code. --- Notes: Version 2: - reworded error message src/lxc/lxc_driver.c | 22 +++++++++++++--------- src/qemu/qemu_driver.c | 24 ++++++++++++++---------- 2 files changed, 27 insertions(+), 19 deletions(-) diff --git a/src/lxc/lxc_driver.c b/src/lxc/lxc_driver.c index 3adb21d..fea9599 100644 --- a/src/lxc/lxc_driver.c +++ b/src/lxc/lxc_driver.c @@ -742,18 +742,22 @@ static int lxcDomainSetMemoryFlags(virDomainPtr dom, unsigned long newmem, goto cleanup; } } else { - unsigned long oldmax = 0; - - if (flags & VIR_DOMAIN_AFFECT_LIVE) - oldmax = vm->def->mem.max_balloon; - if (flags & VIR_DOMAIN_AFFECT_CONFIG) { - if (!oldmax || oldmax > persistentDef->mem.max_balloon) - oldmax = persistentDef->mem.max_balloon; + if (flags & VIR_DOMAIN_AFFECT_LIVE && + newmem > vm->def->mem.max_balloon) { + virReportError(VIR_ERR_INVALID_ARG, + _("new memory value '%lu' cannot be greater than " + "the maximum value '%llu' for the live instance"), + newmem, vm->def->mem.max_balloon); + goto cleanup; } - if (newmem > oldmax) { + if (flags & VIR_DOMAIN_AFFECT_CONFIG && + newmem > persistentDef->mem.max_balloon) { virReportError(VIR_ERR_INVALID_ARG, - "%s", _("Cannot set memory higher than max memory")); + _("new memory value '%lu' cannot be greater than " + "the maximum value '%llu' for the persistent " + "configuration"), + newmem, persistentDef->mem.max_balloon); goto cleanup; } diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index 27cb3bf..bf19de8 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -2326,18 +2326,22 @@ static int qemuDomainSetMemoryFlags(virDomainPtr dom, unsigned long newmem, } else { /* resize the current memory */ - unsigned long oldmax = 0; - - if (flags & VIR_DOMAIN_AFFECT_LIVE) - oldmax = vm->def->mem.max_balloon; - if (flags & VIR_DOMAIN_AFFECT_CONFIG) { - if (!oldmax || oldmax > persistentDef->mem.max_balloon) - oldmax = persistentDef->mem.max_balloon; + if (flags & VIR_DOMAIN_AFFECT_LIVE && + newmem > vm->def->mem.max_balloon) { + virReportError(VIR_ERR_INVALID_ARG, + _("new memory value '%lu' cannot be greater than " + "the maximum value '%llu' for the live instance"), + newmem, vm->def->mem.max_balloon); + goto endjob; } - if (newmem > oldmax) { - virReportError(VIR_ERR_INVALID_ARG, "%s", - _("cannot set memory higher than max memory")); + if (flags & VIR_DOMAIN_AFFECT_CONFIG && + newmem > persistentDef->mem.max_balloon) { + virReportError(VIR_ERR_INVALID_ARG, + _("new memory value '%lu' cannot be greater than " + "the maximum value '%llu' for the persistent " + "configuration"), + newmem, persistentDef->mem.max_balloon); goto endjob; } -- 2.2.2

As there are two possible approaches to define a domain's memory size - one used with legacy, non-NUMA VMs configured in the <memory> element and per-node based approach on NUMA machines - the user needs to make sure that both are specified correctly in the NUMA case. To avoid this burden on the user I'd like to replace the NUMA case with automatic totaling of the memory size. To achieve this I need to replace direct access to the virDomainMemtune's 'max_balloon' field with two separate getters depending on the desired size. The two sizes are needed as: 1) Startup memory size doesn't include memory modules in some hypervisors. 2) After startup these count as the usable memory size. Note that the comments for the functions are future aware and document state that will be present after a few later patches. --- Notes: Version 2: - renamed virDomainDefGetMemoryCurrent to virDomainDefGetMemoryActual - changed to the initial memory accessor when starting VMs in LXC, phyp and libxl src/conf/domain_conf.c | 66 ++++++++++++++++++++++++++++++++++------ src/conf/domain_conf.h | 4 +++ src/hyperv/hyperv_driver.c | 2 +- src/libvirt_private.syms | 3 ++ src/libxl/libxl_conf.c | 2 +- src/libxl/libxl_driver.c | 8 ++--- src/lxc/lxc_cgroup.c | 2 +- src/lxc/lxc_driver.c | 14 ++++----- src/lxc/lxc_fuse.c | 4 +-- src/lxc/lxc_native.c | 4 +-- src/openvz/openvz_driver.c | 2 +- src/parallels/parallels_driver.c | 2 +- src/parallels/parallels_sdk.c | 12 ++++---- src/phyp/phyp_driver.c | 11 ++++--- src/qemu/qemu_command.c | 18 +++++++---- src/qemu/qemu_driver.c | 23 +++++++------- src/qemu/qemu_hotplug.c | 8 +++-- src/qemu/qemu_process.c | 2 +- src/test/test_driver.c | 8 ++--- src/uml/uml_driver.c | 8 ++--- src/vbox/vbox_common.c | 4 +-- src/vmware/vmware_driver.c | 2 +- src/vmx/vmx.c | 12 ++++---- src/xen/xm_internal.c | 14 ++++----- src/xenapi/xenapi_driver.c | 2 +- src/xenapi/xenapi_utils.c | 4 +-- src/xenconfig/xen_common.c | 8 +++-- src/xenconfig/xen_sxpr.c | 9 +++--- 28 files changed, 164 insertions(+), 94 deletions(-) diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index d95dd3e..b41ae17 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -3174,24 +3174,26 @@ virDomainDefPostParseInternal(virDomainDefPtr def, return -1; } - if (def->mem.cur_balloon > def->mem.max_balloon) { + if (def->mem.cur_balloon > virDomainDefGetMemoryActual(def)) { /* Older libvirt could get into this situation due to * rounding; if the discrepancy is less than 4MiB, we silently * round down, otherwise we flag the issue. */ if (VIR_DIV_UP(def->mem.cur_balloon, 4096) > - VIR_DIV_UP(def->mem.max_balloon, 4096)) { + VIR_DIV_UP(virDomainDefGetMemoryActual(def), 4096)) { virReportError(VIR_ERR_XML_ERROR, _("current memory '%lluk' exceeds " "maximum '%lluk'"), - def->mem.cur_balloon, def->mem.max_balloon); + def->mem.cur_balloon, + virDomainDefGetMemoryActual(def)); return -1; } else { VIR_DEBUG("Truncating current %lluk to maximum %lluk", - def->mem.cur_balloon, def->mem.max_balloon); - def->mem.cur_balloon = def->mem.max_balloon; + def->mem.cur_balloon, + virDomainDefGetMemoryActual(def)); + def->mem.cur_balloon = virDomainDefGetMemoryActual(def); } } else if (def->mem.cur_balloon == 0) { - def->mem.cur_balloon = def->mem.max_balloon; + def->mem.cur_balloon = virDomainDefGetMemoryActual(def); } /* @@ -6891,6 +6893,51 @@ virDomainParseMemory(const char *xpath, } +/** + * virDomainDefGetMemoryInitial: + * @def: domain definition + * + * Returns the size of the initial amount of guest memory.
