[libvirt] Some questions about virConnectAuthCallbackPtr
by Richard W.M. Jones 15 Oct '12

15 Oct '12

Some questions which seem to be left ambigious by the documentation for virConnectAuthCallbackPtr: http://libvirt.org/html/libvirt-libvirt.html#virConnectAuthCallbackPtr (1) For a single open, can this be called multiple times? I'm thinking, some authentication methods might give the user N attempts at typing the password, which might result in N callbacks here. (2) The documentation says: "Returns: 0 if all interactions were filled, or -1 upon error". However it also says "If an interaction cannot be filled, fill in NULL and 0". Does that mean it's OK (not an error, return 0) if a result field is set to NULL?

[libvirt] [PATCH 0/3] Add option to selectively enable IPv4/v6 forwarding
by Benjamin Cama 15 Oct '12

15 Oct '12

Hi, Currently, when IP forwarding is enabled in a network element, libvirt enables forwarding for IPv4/v6 on the OS if the bridge has some IP address of that family. In some circumstances, one could only want forwarding for one family and not the other, even if both address families are present; for example, forwarding only IPv6 but still have some RFC1918 addresses on the “local” network as a backup stack, or playing with IPv6 using (not forwarded) ULA addresses, having some IPv4 NATed forwarding, without loosing IPv6 connectivity because enabling it will disable auto-configuration (my case). This patch adds a new optional "family" attribute to the "forward" element, allowing selective forwarding: it can be set to "ipv4" or "ipv6". If not present, the usual behavior of libvirt is kept, forwarding trafic for whichever family there is an address on the bridge. The first patch also remove libvirt's ability to set forwarding; I think it should only check for it, letting the administrator enable it the usual way (/etc/sysctl.conf or wathever) if he really wants it. In my case, this behavior caused me to loose IPv6 connectivity when adding some ULA addresse to my VMs bridge, because IPv6 forwarding was enabled in my back. Regards, Benjamin Cama (3): Only check for IP forwarding, do not enable it Add a "forward family" option Take the forwarding family into account src/conf/network_conf.c | 58 ++++++++++++++++++++++++++++++- src/conf/network_conf.h | 1 + src/network/bridge_driver.c | 81 +++++++++++++++++++++++++++++++++--------- 3 files changed, 121 insertions(+), 19 deletions(-) -- 1.7.2.5

[libvirt] [PATCHv3] Add support for SUSPEND_DISK event
by Martin Kletzander 15 Oct '12

15 Oct '12

This patch adds support for SUSPEND_DISK event; both lifecycle and separated. The support is added for QEMU, machines are changed to PMSUSPENDED, but as QEMU sends SHUTDOWN afterwards, the state changes to shut-off. This and much more needs to be done in order for libvirt to work with transient devices, wake-ups etc. This patch is not aiming for that functionality. --- daemon/remote.c | 25 +++++++++++ examples/domain-events/events-c/event-test.c | 22 +++++++++- examples/domain-events/events-python/event-test.py | 3 +- include/libvirt/libvirt.h.in | 29 +++++++++++++ python/libvirt-override-virConnect.py | 9 ++++ python/libvirt-override.c | 50 ++++++++++++++++++++++ src/conf/domain_event.c | 30 ++++++++++++- src/conf/domain_event.h | 4 ++ src/libvirt_private.syms | 2 + src/qemu/qemu_monitor.c | 10 +++++ src/qemu/qemu_monitor.h | 3 ++ src/qemu/qemu_monitor_json.c | 9 ++++ src/qemu/qemu_process.c | 47 ++++++++++++++++++++ src/remote/remote_driver.c | 31 ++++++++++++++ src/remote/remote_protocol.x | 7 ++- src/remote_protocol-structs | 4 ++ 16 files changed, 281 insertions(+), 4 deletions(-) diff --git a/daemon/remote.c b/daemon/remote.c index e7fe128..2d3f401 100644 --- a/daemon/remote.c +++ b/daemon/remote.c @@ -608,6 +608,30 @@ remoteRelayDomainEventBalloonChange(virConnectPtr conn ATTRIBUTE_UNUSED, } +static int remoteRelayDomainEventPMSuspendDisk(virConnectPtr conn ATTRIBUTE_UNUSED, + virDomainPtr dom, + int reason ATTRIBUTE_UNUSED, + void *opaque) { + virNetServerClientPtr client = opaque;

[libvirt] [PATCH] Add support for SUSPEND_DISK event
by Martin Kletzander 15 Oct '12

15 Oct '12

This patch adds support for SUSPEND_DISK event; both lifecycle and separated. The support is added for QEMU, machines are changed to PMSUSPENDED, but as QEMU sends SHUTDOWN afterwards, the state changes to shut-off. This and much more needs to be done in order for libvirt to work with transient devices, wake-ups etc. This patch is not aiming for that functionality. --- daemon/remote.c | 25 +++++++++++ examples/domain-events/events-c/event-test.c | 22 +++++++++- examples/domain-events/events-python/event-test.py | 3 +- include/libvirt/libvirt.h.in | 29 +++++++++++++ python/libvirt-override-virConnect.py | 9 ++++ python/libvirt-override.c | 50 ++++++++++++++++++++++ src/conf/domain_event.c | 32 +++++++++++++- src/conf/domain_event.h | 4 ++ src/libvirt_private.syms | 2 + src/qemu/qemu_monitor.c | 10 +++++ src/qemu/qemu_monitor.h | 3 ++ src/qemu/qemu_monitor_json.c | 9 ++++ src/qemu/qemu_process.c | 47 ++++++++++++++++++++ src/remote/remote_driver.c | 31 ++++++++++++++ src/remote/remote_protocol.x | 7 ++- src/remote_protocol-structs | 4 ++ 16 files changed, 282 insertions(+), 5 deletions(-) diff --git a/daemon/remote.c b/daemon/remote.c index e7fe128..58017e5 100644 --- a/daemon/remote.c +++ b/daemon/remote.c @@ -608,6 +608,30 @@ remoteRelayDomainEventBalloonChange(virConnectPtr conn ATTRIBUTE_UNUSED, } +static int remoteRelayDomainEventSuspendDisk(virConnectPtr conn ATTRIBUTE_UNUSED, + virDomainPtr dom, + int reason ATTRIBUTE_UNUSED, + void *opaque) { + virNetServerClientPtr client = opaque;

[libvirt] [PATCH] util: switch virLogEatParams to virLogSource
by Ján Tomko 15 Oct '12

15 Oct '12

Commit e8fd8757c89abbd38571092bbb987650b7658aec changed 'const char *' category to virLogSource enum.

[libvirt] [PATCH] node_memory: Add new parameter field to tune the new sysfs knob
by Osier Yang 15 Oct '12

15 Oct '12

Upstream kernel introduced new sysfs knob "merge_across_nodes" to specify if pages from different numa nodes can be merged. When set to 0, only pages which physically reside in the memory area of same NUMA node can be merged. When set to 1, pages from all nodes can be merged. This patch supports the tuning by adding new param field "shm-merge-across-nodes". --- Perhaps two bool options like "--disable-shm-merge-across-nodes", and "--enable-shm-merge-across-nodes" are good, but could the kernel sysfs knob have other values beyond 0 and 1 in future? --- include/libvirt/libvirt.h.in | 10 ++++++++++ src/nodeinfo.c | 26 +++++++++++++++++++++++--- tools/virsh-host.c | 20 ++++++++++++++++++++ tools/virsh.pod | 5 ++++- 4 files changed, 57 insertions(+), 4 deletions(-) diff --git a/include/libvirt/libvirt.h.in b/include/libvirt/libvirt.h.in index 81f12a4..56ee2f5 100644 --- a/include/libvirt/libvirt.h.in +++ b/include/libvirt/libvirt.h.in @@ -4489,6 +4489,16 @@ typedef virMemoryParameter *virMemoryParameterPtr; */ # define VIR_NODE_MEMORY_SHARED_FULL_SCANS "shm_full_scans" +/* VIR_NODE_MEMORY_SHARED_MERGE_ACROSS_NODES: + * + * Macro for typed parameter that represents whether pages from + * different NUMA nodes can be merged, when its value is 0, only + * pages which physically reside in the memory area of same NUMA + * node are merged, otherwise pages from all nodes can be merged. + */ +# define VIR_NODE_MEMORY_SHARED_MERGE_ACROSS_NODES "shm_merge_across_nodes" + + int virNodeGetMemoryParameters(virConnectPtr conn, virTypedParameterPtr params, int *nparams, diff --git a/src/nodeinfo.c b/src/nodeinfo.c index 021eb05..6002789 100644 --- a/src/nodeinfo.c +++ b/src/nodeinfo.c @@ -1004,6 +1004,13 @@ nodeSetMemoryParameters(virConnectPtr conn ATTRIBUTE_UNUSED, /* Out of memory */ if (ret == -2) return -1; + } else if (STREQ(param->field, + VIR_NODE_MEMORY_SHARED_MERGE_ACROSS_NODES)) { + ret = nodeSetMemoryParameterValue("merge_across_nodes", param); + + /* Out of memory */ + if (ret == -2) + return -1; } } @@ -1039,8 +1046,9 @@ nodeGetMemoryParameterValue(const char *field, if ((tmp = strchr(buf, '\n'))) *tmp = '\0'; - if (STREQ(field, "pages_to_scan") || - STREQ(field, "sleep_millisecs")) + if (STREQ(field, "pages_to_scan") || + STREQ(field, "sleep_millisecs") || + STREQ(field, "merge_across_nodes")) rc = virStrToLong_ui(buf, NULL, 10, (unsigned int *)value); else if (STREQ(field, "pages_shared") || STREQ(field, "pages_sharing") || @@ -1063,7 +1071,7 @@ cleanup: } #endif -#define NODE_MEMORY_PARAMETERS_NUM 7 +#define NODE_MEMORY_PARAMETERS_NUM 8 int nodeGetMemoryParameters(virConnectPtr conn ATTRIBUTE_UNUSED, virTypedParameterPtr params ATTRIBUTE_UNUSED, @@ -1075,6 +1083,7 @@ nodeGetMemoryParameters(virConnectPtr conn ATTRIBUTE_UNUSED, #ifdef __linux__ unsigned int pages_to_scan; unsigned int sleep_millisecs; + unsigned int merge_across_nodes; unsigned long long pages_shared; unsigned long long pages_sharing; unsigned long long pages_unshared; @@ -1168,6 +1177,17 @@ nodeGetMemoryParameters(virConnectPtr conn ATTRIBUTE_UNUSED, break; + case 7: + if (nodeGetMemoryParameterValue("merge_across_nodes", + &merge_across_nodes) < 0) + return -1; + + if (virTypedParameterAssign(param, VIR_NODE_MEMORY_SHARED_MERGE_ACROSS_NODES, + VIR_TYPED_PARAM_UINT, merge_across_nodes) < 0) + return -1; + + break; + default: break; } diff --git a/tools/virsh-host.c b/tools/virsh-host.c index 2c46336..62ecafc 100644 --- a/tools/virsh-host.c +++ b/tools/virsh-host.c @@ -900,6 +900,8 @@ static const vshCmdOptDef opts_node_memory_tune[] = { {"shm-sleep-millisecs", VSH_OT_INT, VSH_OFLAG_NONE, N_("number of millisecs the shared memory service should " "sleep before next scan")}, + {"shm-merge-across-nodes", VSH_OT_INT, VSH_OFLAG_NONE, + N_("Specifies if pages from different numa nodes can be merged")}, {NULL, 0, 0, NULL} }; @@ -911,6 +913,7 @@ cmdNodeMemoryTune(vshControl *ctl, const vshCmd *cmd) unsigned int flags = 0; unsigned int shm_pages_to_scan = 0; unsigned int shm_sleep_millisecs = 0; + unsigned int shm_merge_across_nodes = 0; bool ret = false; int i = 0; @@ -926,12 +929,21 @@ cmdNodeMemoryTune(vshControl *ctl, const vshCmd *cmd) return false; } + if (vshCommandOptUInt(cmd, "shm-merge-across-nodes", + &shm_merge_across_nodes) < 0) { + vshError(ctl, "%s", _("invalid shm-merge-across-nodes number")); + return false; + } + if (shm_pages_to_scan) nparams++; if (shm_sleep_millisecs) nparams++; + if (shm_merge_across_nodes) + nparams++; + if (nparams == 0) { /* Get the number of memory parameters */ if (virNodeGetMemoryParameters(ctl->conn, NULL, &nparams, flags) != 0) { @@ -983,6 +995,14 @@ cmdNodeMemoryTune(vshControl *ctl, const vshCmd *cmd) goto error; } + if (i < nparams && shm_merge_across_nodes) { + if (virTypedParameterAssign(&params[i++], + VIR_NODE_MEMORY_SHARED_MERGE_ACROSS_NODES, + VIR_TYPED_PARAM_UINT, + shm_merge_across_nodes) < 0) + goto error; + } + if (virNodeSetMemoryParameters(ctl->conn, params, nparams, flags) != 0) goto error; else diff --git a/tools/virsh.pod b/tools/virsh.pod index 2120429..d975f06 100644 --- a/tools/virsh.pod +++ b/tools/virsh.pod @@ -299,7 +299,10 @@ Allows you to display or set the node memory parameters.
