[libvirt] [PATCH] qemu: Pin the emulator when only cpuset is specified
by Martin Kletzander 22 Oct '12

22 Oct '12

According to our recent changes (clarifications), we should be pinning qemu's emulator processes using the <vcpu> 'cpuset' attribute in case there is no <emulatorpin> specified. This however doesn't work entirely as expected and this patch should resolve all the remaining issues. --- src/qemu/qemu_cgroup.c | 25 ++++++++++++++++--------- src/qemu/qemu_cgroup.h | 4 ++-- src/qemu/qemu_driver.c | 3 ++- src/qemu/qemu_process.c | 16 ++++++++-------- 4 files changed, 28 insertions(+), 20 deletions(-) diff --git a/src/qemu/qemu_cgroup.c b/src/qemu/qemu_cgroup.c index 166f9b9..6b94686 100644 --- a/src/qemu/qemu_cgroup.c +++ b/src/qemu/qemu_cgroup.c @@ -501,7 +501,7 @@ int qemuSetupCgroupVcpuPin(virCgroupPtr cgroup, for (i = 0; i < nvcpupin; i++) { if (vcpuid == vcpupin[i]->vcpuid) { - return qemuSetupCgroupEmulatorPin(cgroup, vcpupin[i]); + return qemuSetupCgroupEmulatorPin(cgroup, vcpupin[i]->cpumask); } } @@ -509,12 +509,12 @@ int qemuSetupCgroupVcpuPin(virCgroupPtr cgroup, } int qemuSetupCgroupEmulatorPin(virCgroupPtr cgroup, - virDomainVcpuPinDefPtr vcpupin) + virBitmapPtr cpumask) { int rc = 0; char *new_cpus = NULL; - new_cpus = virBitmapFormat(vcpupin->cpumask); + new_cpus = virBitmapFormat(cpumask); if (!new_cpus) { virReportError(VIR_ERR_INTERNAL_ERROR, "%s", _("failed to convert cpu mask")); @@ -643,6 +643,7 @@ cleanup: int qemuSetupCgroupForEmulator(struct qemud_driver *driver, virDomainObjPtr vm) { + virBitmapPtr cpumask = NULL; virCgroupPtr cgroup = NULL; virCgroupPtr cgroup_emulator = NULL; virDomainDefPtr def = vm->def; @@ -690,12 +691,18 @@ int qemuSetupCgroupForEmulator(struct qemud_driver *driver, } } - if (def->cputune.emulatorpin && - qemuCgroupControllerActive(driver, VIR_CGROUP_CONTROLLER_CPUSET)) { - rc = qemuSetupCgroupEmulatorPin(cgroup_emulator, - def->cputune.emulatorpin); - if (rc < 0) - goto cleanup; + if (def->cputune.emulatorpin) + cpumask = def->cputune.emulatorpin->cpumask; + else if (def->cpumask) + cpumask = def->cpumask; + + if (cpumask) { + if (qemuCgroupControllerActive(driver, VIR_CGROUP_CONTROLLER_CPUSET)) { + rc = qemuSetupCgroupEmulatorPin(cgroup_emulator, cpumask); + if (rc < 0) + goto cleanup; + } + cpumask = NULL; /* sanity */ } if (period || quota) { diff --git a/src/qemu/qemu_cgroup.h b/src/qemu/qemu_cgroup.h index b7b0211..362080a 100644 --- a/src/qemu/qemu_cgroup.h +++ b/src/qemu/qemu_cgroup.h @@ -1,7 +1,7 @@ /* * qemu_cgroup.h: QEMU cgroup management * - * Copyright (C) 2006-2007, 2009-2011 Red Hat, Inc. + * Copyright (C) 2006-2007, 2009-2012 Red Hat, Inc. * Copyright (C) 2006 Daniel P.

[libvirt] [PATCH] migrate: v2: use VIR_DOMAIN_XML_MIGRATABLE when available
by Ján Tomko 22 Oct '12

22 Oct '12

In v2 migration protocol, XML is obtained by calling domainGetXMLDesc. This includes the default USB controller in XML, which breaks migration to older libvirt (before 0.9.2). Commit 409b5f549530e7b3a33f4505f2cad2e26896107c qemu: Emit compatible XML when migrating a domain only fixed this for v3 migration. This patch uses the new VIR_DOMAIN_XML_MIGRATABLE flag (detected by VIR_DRV_FEATURE_XML_MIGRATABLE) to obtain XML without the default controller, enabling backward v2 migration. --- src/libvirt.c | 13 ++++++++++--- src/libvirt_internal.h | 5 +++++ src/qemu/qemu_driver.c | 1 + 3 files changed, 16 insertions(+), 3 deletions(-) diff --git a/src/libvirt.c b/src/libvirt.c index e3ddf27..f6f5b91 100644 --- a/src/libvirt.c +++ b/src/libvirt.c @@ -4620,6 +4620,7 @@ virDomainMigrateVersion2 (virDomainPtr domain, int cookielen = 0, ret; virDomainInfo info; virErrorPtr orig_err = NULL; + unsigned int getxml_flags = 0; int cancelled; VIR_DOMAIN_DEBUG(domain, "dconn=%p, flags=%lx, dname=%s, uri=%s, bandwidth=%lu", @@ -4646,9 +4647,15 @@ virDomainMigrateVersion2 (virDomainPtr domain, virDispatchError(domain->conn); return NULL; } - dom_xml = domain->conn->driver->domainGetXMLDesc(domain, - VIR_DOMAIN_XML_SECURE | - VIR_DOMAIN_XML_UPDATE_CPU); + + if (VIR_DRV_SUPPORTS_FEATURE(domain->conn->driver, domain->conn, + VIR_DRV_FEATURE_XML_MIGRATABLE)) { + getxml_flags |= VIR_DOMAIN_XML_MIGRATABLE; + } else { + getxml_flags |= VIR_DOMAIN_XML_SECURE | VIR_DOMAIN_XML_UPDATE_CPU; + } + + dom_xml = domain->conn->driver->domainGetXMLDesc(domain, getxml_flags); if (!dom_xml) return NULL; diff --git a/src/libvirt_internal.h b/src/libvirt_internal.h index 23e7153..71483e4 100644 --- a/src/libvirt_internal.h +++ b/src/libvirt_internal.h @@ -95,6 +95,11 @@ enum { * messages). */ VIR_DRV_FEATURE_PROGRAM_KEEPALIVE = 10, + + /* + * Support for VIR_DOMAIN_XML_MIGRATABLE flag in domainGetXMLDesc + */ + VIR_DRV_FEATURE_XML_MIGRATABLE = 11, }; diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index 76730c6..0c35dad 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -1130,6 +1130,7 @@ qemudSupportsFeature (virConnectPtr conn ATTRIBUTE_UNUSED, int feature) case VIR_DRV_FEATURE_MIGRATE_CHANGE_PROTECTION: case VIR_DRV_FEATURE_FD_PASSING: case VIR_DRV_FEATURE_TYPED_PARAM_STRING: + case VIR_DRV_FEATURE_XML_MIGRATABLE: return 1; default: return 0; -- 1.7.8.6

[libvirt] [PATCH] network: always create dnsmasq hosts and addnhosts files, even if empty
by Laine Stump 21 Oct '12

21 Oct '12

This fixes the problem reported in: https://bugzilla.redhat.com/show_bug.cgi?id=868389 Previously, the dnsmasq hosts file (used for static dhcp entries, and addnhosts file (used for additional dns host entries) were only created/referenced on the dnsmasq commandline if there was something to put in them at the time the network was started. Once we can update a network definition while it's active (which is now possible with virNetworkUpdate), this is no longer a valid strategy - if there were 0 dhcp static hosts (resulting in no reference to the hosts file on the commandline), then one was later added, the commandline wouldn't have linked dnsmasq up to the file, so even though we create it, dnsmasq doesn't pay any attention. The solution is to just always create these files and reference them on the dnsmasq commandline (almost always, anyway). That way dnsmasq can notice when a new entry is added at runtime (a SIGHUP is sent to dnsmasq by virNetworkUdpate whenever a host entry is added or removed) The exception to this is that the dhcp static hosts file isn't created if there are no lease ranges *and* no static hosts. This is because in this case dnsmasq won't be setup to listen for dhcp requests anyway - in that case, if the count of dhcp hosts goes from 0 to 1, dnsmasq will need to be restarted anyway (to get it listening on the dhcp port). Likewise, if the dhcp hosts count goes from 1 to 0 (and there are no dhcp ranges) we need to restart dnsmasq so that it will stop listening on port 67. These special situations are handled in the bridge driver's networkUpdate() by checking for ((bool) nranges||nhosts) both before and after the update, and triggering a dnsmasq restart if the before and after don't match. --- src/network/bridge_driver.c | 56 +++++++++++++++++++--- src/util/dnsmasq.c | 12 +++-- tests/networkxml2argvdata/isolated-network.argv | 4 +- .../nat-network-dns-srv-record-minimal.argv | 3 +- .../nat-network-dns-srv-record.argv | 3 +- .../nat-network-dns-txt-record.argv | 3 +- tests/networkxml2argvdata/nat-network.argv | 3 +- tests/networkxml2argvdata/netboot-network.argv | 5 +- .../networkxml2argvdata/netboot-proxy-network.argv | 2 + tests/networkxml2argvdata/routed-network.argv | 3 +- 10 files changed, 75 insertions(+), 19 deletions(-) diff --git a/src/network/bridge_driver.c b/src/network/bridge_driver.c index fa909a1..1c97f29 100644 --- a/src/network/bridge_driver.c +++ b/src/network/bridge_driver.c @@ -751,12 +751,19 @@ networkBuildDnsmasqArgv(virNetworkObjPtr network, if (networkBuildDnsmasqHostsfile(dctx, ipdef, network->def->dns) < 0) goto cleanup;

[libvirt] [PATCH] Fix disabling of apparmor security driver
by Christophe Fergeau 21 Oct '12
