[libvirt] [PATCH v3] storage backend: Add sheepdog support
by Sebastian Wiedenroth 18 Jul '12

18 Jul '12

This patch brings support to manage sheepdog pools and volumes to libvirt. It uses the "collie" command-line utility that comes with sheepdog for that. A sheepdog pool in libvirt maps to a sheepdog cluster. It needs a host and port to connect to, which in most cases is just going to be the default of localhost on port 7000. A sheepdog volume in libvirt maps to a sheepdog vdi. To create one specify the pool, a name and the capacity. Volumes can also be resized later. In the volume XML the vdi name has to be put into the <target><path>. To use the volume as a disk source for virtual machines specify the vdi name as "name" attribute of the <source>. The host and port information from the pool are specified inside the host tag. <disk type='network'> ... <source protocol="sheepdog" name="vdi_name"> <host name="localhost" port="7000"/> </source> </disk> To work right this patch parses the output of collie, so it relies on the raw output option. There recently was a bug which caused size information to be reported wrong. This is fixed upstream already and will be in the next release.

[libvirt] [libvirt-glib] Fix *_new_from_xml
by Christophe Fergeau 18 Jul '12

18 Jul '12

For objects with a subtype 'type' attribute, when the _new_from_xml function was called, the 'type' attribute was forcefully set to the right value rather than checking that the passed-in value matches the type of the subclass we are trying to instantiate. This commit changes this, and returns NULL when the value of the 'type' attribute of the passed-in XML document does not match the expected type. --- libvirt-gconfig/libvirt-gconfig-domain-address-pci.c | 2 +- libvirt-gconfig/libvirt-gconfig-domain-address-usb.c | 2 +- libvirt-gconfig/libvirt-gconfig-domain-chardev-source-pty.c | 2 +- libvirt-gconfig/libvirt-gconfig-domain-chardev-source-spicevmc.c | 2 +- libvirt-gconfig/libvirt-gconfig-domain-controller-usb.c | 2 +- libvirt-gconfig/libvirt-gconfig-domain-graphics-sdl.c | 4 +--- libvirt-gconfig/libvirt-gconfig-domain-graphics-spice.c | 4 +--- libvirt-gconfig/libvirt-gconfig-domain-graphics-vnc.c | 4 +--- libvirt-gconfig/libvirt-gconfig-domain-interface-bridge.c | 4 +--- libvirt-gconfig/libvirt-gconfig-domain-interface-network.c | 4 +--- libvirt-gconfig/libvirt-gconfig-domain-interface-user.c | 4 +--- libvirt-gconfig/libvirt-gconfig-domain-timer-pit.c | 2 +- libvirt-gconfig/libvirt-gconfig-domain-timer-rtc.c | 2 +- 13 files changed, 13 insertions(+), 25 deletions(-) diff --git a/libvirt-gconfig/libvirt-gconfig-domain-address-pci.c b/libvirt-gconfig/libvirt-gconfig-domain-address-pci.c index 48e3872..5199b8a 100644 --- a/libvirt-gconfig/libvirt-gconfig-domain-address-pci.c +++ b/libvirt-gconfig/libvirt-gconfig-domain-address-pci.c @@ -67,7 +67,7 @@ GVirConfigDomainAddressPci *gvir_config_domain_address_pci_new_from_xml(const gc object = gvir_config_object_new_from_xml(GVIR_CONFIG_TYPE_DOMAIN_ADDRESS_PCI, "address", NULL, xml, error);

[libvirt] virDomainMemoryStats call
by Parakkal, Navin S 18 Jul '12

18 Jul '12

Hi, I'm using the API virDomainMemoryStats to fetch memory stats for a domain/guest on Fedora 16/RHEL 6.3 . I don't get these counters filled up VIR_DOMAIN_MEMORY_STAT_UNUSED, VIR_DOMAIN_MEMORY_STAT_ACTUAL_BALLOON,VIR_DOMAIN_MEMORY_STAT_AVAILABLE , VIR_DOMAIN_MEMORY_STAT_MAJOR_FAULT and VIR_DOMAIN_MEMORY_STAT_MINOR_FAULT. The version of libvirt 0.9.11 on Fedora 16 . How to get all the counters filled up ? Should I take a specific version of qemu or should I do some config settings so that these values are filled up ? P.S. Please copy me in reply Regards, Navin Parakkal HP Software

[libvirt] [PATCH] remote: Fix locking in stream APIs
by Jiri Denemark 18 Jul '12

18 Jul '12

Remote driver needs to make sure the driver lock is released before entering client IO loop as that may block indefinitely in poll(). As a direct consequence of not following this in stream APIs, tunneled migration to a destination host which becomes non-responding may block qemu driver. Luckily, if keepalive is turned for p2p migrations, both remote and qemu drivers will get automagically unblocked after keepalive timeout. --- src/remote/remote_driver.c | 40 ++++++++++++++++++++++++++++------------ 1 file changed, 28 insertions(+), 12 deletions(-) diff --git a/src/remote/remote_driver.c b/src/remote/remote_driver.c index 3314f80..acae5d0 100644 --- a/src/remote/remote_driver.c +++ b/src/remote/remote_driver.c @@ -3976,12 +3976,14 @@ remoteStreamSend(virStreamPtr st, VIR_DEBUG("st=%p data=%p nbytes=%zu", st, data, nbytes); struct private_data *priv = st->conn->privateData; virNetClientStreamPtr privst = st->privateData; - int rv = -1; - - remoteDriverLock(priv); + int rv; if (virNetClientStreamRaiseError(privst)) - goto cleanup; + return -1; + + remoteDriverLock(priv); + priv->localUses++; + remoteDriverUnlock(priv); rv = virNetClientStreamSendPacket(privst, priv->client, @@ -3989,9 +3991,9 @@ remoteStreamSend(virStreamPtr st, data, nbytes); -cleanup: + remoteDriverLock(priv); + priv->localUses--; remoteDriverUnlock(priv); - return rv; } @@ -4004,12 +4006,14 @@ remoteStreamRecv(virStreamPtr st, VIR_DEBUG("st=%p data=%p nbytes=%zu", st, data, nbytes); struct private_data *priv = st->conn->privateData; virNetClientStreamPtr privst = st->privateData; - int rv = -1; - - remoteDriverLock(priv); + int rv; if (virNetClientStreamRaiseError(privst)) - goto cleanup; + return -1; + + remoteDriverLock(priv); + priv->localUses++; + remoteDriverUnlock(priv); rv = virNetClientStreamRecvPacket(privst, priv->client, @@ -4019,9 +4023,9 @@ remoteStreamRecv(virStreamPtr st, VIR_DEBUG("Done %d", rv); -cleanup: + remoteDriverLock(priv); + priv->localUses--; remoteDriverUnlock(priv); - return rv; } @@ -4138,12 +4142,18 @@ remoteStreamFinish(virStreamPtr st) if (virNetClientStreamRaiseError(privst)) goto cleanup; + priv->localUses++; + remoteDriverUnlock(priv); + ret = virNetClientStreamSendPacket(privst, priv->client, VIR_NET_OK, NULL, 0); + remoteDriverLock(priv); + priv->localUses--; + cleanup: virNetClientRemoveStream(priv->client, privst); virNetClientStreamFree(privst); @@ -4167,12 +4177,18 @@ remoteStreamAbort(virStreamPtr st) if (virNetClientStreamRaiseError(privst)) goto cleanup; + priv->localUses++; + remoteDriverUnlock(priv); + ret = virNetClientStreamSendPacket(privst, priv->client, VIR_NET_ERROR, NULL, 0); + remoteDriverLock(priv); + priv->localUses--; + cleanup: virNetClientRemoveStream(priv->client, privst); virNetClientStreamFree(privst); -- 1.7.11.1

[libvirt] IPs via DHCP for guest domains
by Fong Vang 17 Jul '12

17 Jul '12

I'm curious to know how you are providing IPs for your Windows VMs when connected via a bridge. Since broadcasts from the VMs are going out the bridged interface, I'm thinking about implementing ebtables to block dhcp broadcasts from going in/out the interface so that dnsmasq would only respond to dhcp requests from the local guest VMs. Before I venture down this path, I thought I might ask if there's an easier way to do this with libvirt. Thanks for any help.

[libvirt] [PATCH 0/4] qemu: configurable port boundaries for remote displays
by Martin Kletzander 17 Jul '12

17 Jul '12

This series introduces a possibility to change default minimal and maximal port numbers that are used to specify a remote display port for both VNC and SPICE. Because the code was a bit messy, PATCH 1/4 cleans up few things needed to make a clean run of PATCH 2/4, that does the main change in the code. I also noticed two things that could be changed and it made sense for me to do that, but these are nowhere near any importance, so feel free to reject them if your heart feels that way. PATCH 3/4 rewords three messages and applying it would mean that they are not translated. Even though I think it makes more sense this way, I'm not a good English speaker, so that's more like an RFC. PATCH 4/4 makes more flexible port searching available, but is used on one place and because there are so many ports, it won't be that used, I guess. P.S.: this is basically v2 for https://www.redhat.com/archives/libvir-list/2012-May/msg01081.html but it changed a lot and the name is also different, so I didn't want to create any confision.

[VIR_MAC_BUFLEN]' with virMacAddr and introduce usage of above functions where necessary. --- src/conf/capabilities.c | 4 - src/conf/capabilities.h | 4 - src/conf/domain_audit.c | 6 - src/conf/domain_conf.c | 32 ++++----- src/conf/domain_conf.h | 6 - src/conf/network_conf.c | 14 ++-- src/conf/network_conf.h | 2 src/conf/nwfilter_conf.c | 17 +--- src/conf/nwfilter_conf.h | 14 +--- src/conf/nwfilter_params.h | 1 src/libvirt_private.syms | 5 + src/libxl/libxl_conf.c | 2 src/lxc/lxc_driver.c | 6 - src/network/bridge_driver.c | 2 src/nwfilter/nwfilter_dhcpsnoop.c | 16 ++-- src/nwfilter/nwfilter_dhcpsnoop.h | 2 src/nwfilter/nwfilter_ebiptables_driver.c | 6 - src/nwfilter/nwfilter_gentech_driver.c | 8 +- src/nwfilter/nwfilter_gentech_driver.h | 2 src/nwfilter/nwfilter_learnipaddr.c | 29 +++----- src/nwfilter/nwfilter_learnipaddr.h | 4 - src/openvz/openvz_conf.c | 2 src/openvz/openvz_driver.c | 8 +- src/qemu/qemu_bridge_filter.c | 4 - src/qemu/qemu_bridge_filter.h | 4 - src/qemu/qemu_command.c | 22 +++--- src/qemu/qemu_driver.c | 16 ++-- src/qemu/qemu_hostdev.c | 8 +- src/qemu/qemu_hotplug.c | 14 ++-- src/qemu/qemu_migration.c | 6 - src/qemu/qemu_process.c | 4 - src/uml/uml_conf.c | 6 - src/util/ebtables.c | 16 ++-- src/util/ebtables.h | 6 + src/util/virmacaddr.c | 104 +++++++++++++++++++++++++----- src/util/virmacaddr.h | 25 +++++-- src/util/virnetdev.c | 61 ++++++++--------- src/util/virnetdev.h | 11 +-- src/util/virnetdevmacvlan.c | 38 +++++----- src/util/virnetdevmacvlan.h | 11 +-- src/util/virnetdevopenvswitch.c | 2 src/util/virnetdevopenvswitch.h | 2 src/util/virnetdevtap.c | 19 ++--- src/util/virnetdevtap.h | 2 src/util/virnetdevvportprofile.c | 18 ++--- src/util/virnetdevvportprofile.h | 5 - src/util/virnetlink.c | 15 ++-- src/util/virnetlink.h | 7 +- src/vbox/vbox_tmpl.c | 16 ++-- src/vmx/vmx.c | 10 +- src/xen/xend_internal.c | 6 - src/xen/xm_internal.c | 4 - src/xenxs/xen_sxpr.c | 6 - src/xenxs/xen_xm.c | 8 +- tools/virsh.c | 8 +- 55 files changed, 377 insertions(+), 299 deletions(-) Index: libvirt-acl/src/conf/domain_conf.h =================================================================== --- libvirt-acl.orig/src/conf/domain_conf.h +++ libvirt-acl/src/conf/domain_conf.h @@ -785,7 +785,7 @@ struct _virDomainActualNetDef { /* Stores the virtual network interface configuration */ struct _virDomainNetDef { enum virDomainNetType type;

[libvirt] trying to build 0.9.13 on F17: cannot find -lcrypto

In trying to build libvirt 0.9.13 on F17, I'm hitting a link error: ... CCLD libvirt_driver_nodedev.la CCLD libvirt_driver_nwfilter.la /usr/bin/ld: cannot find -lcrypto Full log here: http://kojipkgs.fedoraproject.org//work/tasks/3678/4233678/build.log I think this comes from rbd support, from configure.ac: LIBRBD_LIBS="-lrbd -lrados -lcrypto" from this commit: http://libvirt.org/git/?p=libvirt.git;a=commit;h=74951eadef85e2d100c7dc7bd9… What's missing here? RPM BuildRequires, configure change, ...? Thanks, Cole

[libvirt] ESX: failure while performing "CastFromAnyType"
by Ata E Husain Bohra 17 Jul '12

17 Jul '12

Hi All, I am trying to extend “iscsi” support for iSCSI driver, currently am stuck at getting iSCSI target list from the hypervisor. I am using hostSystem object (propertyNameList is set to “config.storageDevice.hostBusAdapter”) to retrieve list of “HostHostBusAdapter” from ESX, but the call fails to perform “CastFromAnyType” from ObjectContent –> HostHostBusAdapter. The esx_vi_generator.input object definition looks like this: object HostHostBusAdapter String key o String device r Int bus r String status r String model r String driver o String pci o end esx_vi_generaor.py is modified as follows: "HostHostBusAdapter" : Object.FEATURE__ANY_TYPE | Object.FEATURE__LIST, Using gdb, I see the failure occurs at: esx/esx_vi.c:esxVI_List_CastFromAnyType(..) line 1631: .. if (esxVI_AnyType_Deserialize(childNode, &childAnyType) < 0 || castFromAnyTypeFunc(childAnyType, &item) < 0 || esxVI_List_Append(list, item) < 0) { goto cleanup; } .. In one of my earlier patches (subject: Add routines to interface driver) I patched esx_vi_generator.py to deserialize “string list”; as the patch is still under review I manually applied the branch to this branch but no change (did not expect change as structure does not contain any list object). I am wondering what else is missing to make it work. Any suggestion how to debug/fix this issue is highly appreciated. Thanks! Ata

[libvirt] [ANNOUNCE] libvirt-glib 0.1.0 release
by Daniel P. Berrange 16 Jul '12

16 Jul '12

I am pleased to announce that a new release of the libvirt-glib package, version 0.1.0 is now available from ftp://libvirt.org/libvirt/glib/ The packages are GPG signed with Key fingerprint: DAF3 A6FD B26B 6291 2D0E 8E3F BE86 EBB4 1510 4FDF (4096R) New in this release: - Add setters for capabilities CPU config object - Add constructor for capabilities CPU config object - Add config object for domain CPU schema - Add bindings for domain save APIs - Add bindings for storage volume upload/download libvirt-glib comprises three distinct libraries: - libvirt-glib - Integrate with the GLib event loop and error handling - libvirt-gconfig - Representation of libvirt XML documents as GObjects - libvirt-gobject - Mapping of libvirt APIs into the GObject type system NB: While libvirt aims to be API/ABI stable forever, with libvirt-glib we are not yet guaranteeing that libvirt-glib libraries are API/ABI permanently stable. As of the 0.0.8 release, we have tentatively frozen the API/ABI with the intent of being longterm stable hereafter, but there is still a small chance we might find flaws requiring an API/ABI change. The likelihood of this is low, however, and we will strive to avoid it. Follow up comments about libvirt-glib should be directed to the regular libvir-list redhat com development list. Thanks to all the people involved in contributing to this release.

[libvirt] [PATCH] qemu: Fix probing for guest capabilities
by Jiri Denemark 16 Jul '12

16 Jul '12

Even though qemu-kvm binaries can be used in TCG mode, libvirt would only detect them if /dev/kvm was available. Thus, one would need to make a /usr/bin/qemu symlink to be able to use TCG mode with qemu-kvm in an environment without KVM support. And even though QEMU is able to make use of KVM, libvirt would not advertise KVM support unless there was a qemu-kvm symlink available. This patch fixes both issues. --- src/qemu/qemu_capabilities.c | 95 ++++++++++++++++++++++++-------------------- 1 file changed, 53 insertions(+), 42 deletions(-) diff --git a/src/qemu/qemu_capabilities.c b/src/qemu/qemu_capabilities.c index 9e4d927..cbea365 100644 --- a/src/qemu/qemu_capabilities.c +++ b/src/qemu/qemu_capabilities.c @@ -645,6 +645,7 @@ qemuCapsInitGuest(virCapsPtr caps, struct stat st; unsigned int ncpus; virBitmapPtr qemuCaps = NULL; + virBitmapPtr kvmCaps = NULL; int ret = -1; /* Check for existance of base emulator, or alternate base @@ -657,7 +658,12 @@ qemuCapsInitGuest(virCapsPtr caps, binary = virFindFileInPath(info->altbinary); } - /* Can use acceleration for KVM/KQEMU if + /* Ignore binary if extracting version info fails */ + if (binary && + qemuCapsExtractVersionInfo(binary, info->arch, NULL, &qemuCaps) < 0) + VIR_FREE(binary); + + /* qemu-kvm/kvm binaries can only be used if * - host & guest arches match * Or * - hostarch is x86_64 and guest arch is i686 @@ -665,37 +671,44 @@ qemuCapsInitGuest(virCapsPtr caps, */ if (STREQ(info->arch, hostmachine) || (STREQ(hostmachine, "x86_64") && STREQ(info->arch, "i686"))) { - if (access("/dev/kvm", F_OK) == 0) { - const char *const kvmbins[] = { "/usr/libexec/qemu-kvm", /* RHEL */ - "qemu-kvm", /* Fedora */ - "kvm" }; /* Upstream .spec */ + const char *const kvmbins[] = { "/usr/libexec/qemu-kvm", /* RHEL */ + "qemu-kvm", /* Fedora */ + "kvm" }; /* Upstream .spec */ - for (i = 0; i < ARRAY_CARDINALITY(kvmbins); ++i) { - kvmbin = virFindFileInPath(kvmbins[i]); + for (i = 0; i < ARRAY_CARDINALITY(kvmbins); ++i) { + kvmbin = virFindFileInPath(kvmbins[i]); - if (!kvmbin) - continue; + if (!kvmbin) + continue; - haskvm = 1; - if (!binary) - binary = kvmbin; + if (qemuCapsExtractVersionInfo(kvmbin, info->arch, + NULL, &kvmCaps) < 0) { + VIR_FREE(kvmbin); + continue; + } - break; + if (!binary) { + binary = kvmbin; + qemuCaps = kvmCaps; + kvmbin = NULL; + kvmCaps = NULL; } + break; } - - if (access("/dev/kqemu", F_OK) == 0) - haskqemu = 1; } if (!binary) return 0; - /* Ignore binary if extracting version info fails */ - if (qemuCapsExtractVersionInfo(binary, info->arch, NULL, &qemuCaps) < 0) { - ret = 0; - goto cleanup; - } + if (access("/dev/kvm", F_OK) == 0 && + (qemuCapsGet(qemuCaps, QEMU_CAPS_KVM) || + qemuCapsGet(qemuCaps, QEMU_CAPS_ENABLE_KVM) || + kvmbin)) + haskvm = 1; + + if (access("/dev/kqemu", F_OK) == 0 && + qemuCapsGet(qemuCaps, QEMU_CAPS_KQEMU)) + haskqemu = 1; if (stat(binary, &st) == 0) { binary_mtime = st.st_mtime; @@ -787,21 +800,23 @@ qemuCapsInitGuest(virCapsPtr caps, if (haskvm) { virCapsGuestDomainPtr dom; - if (stat(kvmbin, &st) == 0) { - binary_mtime = st.st_mtime; - } else { - char ebuf[1024]; - VIR_WARN("Failed to stat %s, most peculiar : %s", - binary, virStrerror(errno, ebuf, sizeof(ebuf))); - binary_mtime = 0; - } - - if (!STREQ(binary, kvmbin)) { + if (kvmbin) { int probe = 1; + + if (stat(kvmbin, &st) == 0) { + binary_mtime = st.st_mtime; + } else { + char ebuf[1024]; + VIR_WARN("Failed to stat %s, most peculiar : %s", + binary, virStrerror(errno, ebuf, sizeof(ebuf))); + binary_mtime = 0; + } + if (old_caps && binary_mtime) - probe = !qemuCapsGetOldMachines("hvm", info->arch, info->wordsize, - kvmbin, binary_mtime, - old_caps, &machines, &nmachines); + probe = !qemuCapsGetOldMachines("hvm", info->arch, + info->wordsize, kvmbin, + binary_mtime, old_caps, + &machines, &nmachines); if (probe && qemuCapsProbeMachineTypes(kvmbin, qemuCaps, &machines, &nmachines) < 0) @@ -810,7 +825,7 @@ qemuCapsInitGuest(virCapsPtr caps, if ((dom = virCapabilitiesAddGuestDomain(guest, "kvm", - kvmbin, + kvmbin ? kvmbin : binary, NULL, nmachines, machines)) == NULL) { @@ -845,14 +860,10 @@ qemuCapsInitGuest(virCapsPtr caps, ret = 0; cleanup: - if (binary == kvmbin) { - /* don't double free */ - VIR_FREE(binary); - } else { - VIR_FREE(binary); - VIR_FREE(kvmbin); - } + VIR_FREE(binary); + VIR_FREE(kvmbin); qemuCapsFree(qemuCaps); + qemuCapsFree(kvmCaps); return ret; -- 1.7.11.1

Right on the top of http://www.centos.org/docs/5/html/5.2/Virtualization/chap-Virtualization-Ma…, it seems to imply you can load/send scripts to the vm guest using virsh. Is that possible? How and what are the limitations? Can you query the vm guest?

[libvirt] [PATCH 0/2] Avoid touching monitor when fetching guest XML or info
by Guannan Ren 14 Jul '12

14 Jul '12

The virDomainGetXMLDesc and virDomainGetInfo APIs for QEMU suffer from needing to run 'query-balloon' to update the balloon level. This has caused us performance problems and even worse caused us to lock up on a dead QEMU. The following two patches to QEMU add a BALLOON_EVENT and a query-events command to QMP. With those two parts, we can avoiding running the query-balloon command at all. https://lists.gnu.org/archive/html/qemu-devel/2012-05/msg02215.html qemu upstream commit ID: 973603a813c5d60534b4fa0313f83be40e2b9c47 https://lists.gnu.org/archive/html/qemu-devel/2012-05/msg02255.html qemu upstream commit ID: 4860853d60ecea44b65e9cdefce980de3a641dce

[libvirt] [PATCH] Clarify direct migration
by Jiri Denemark 13 Jul '12

When --direct is used when migrating a domain running on a hypervisor that does not support direct migration (such as QEMU), the caller would get the following error message: this function is not supported by the connection driver: virDomainMigrateToURI2 which is a complete nonsense since qemu driver implements virDomainMigrateToURI2. This patch would emit a more sensible error in this case: Requested operation is not valid: direct migration is not supported by the connection driver --- src/libvirt.c | 8 ++++++-- tools/virsh.pod | 3 +++ 2 files changed, 9 insertions(+), 2 deletions(-) diff --git a/src/libvirt.c b/src/libvirt.c index db6ba15..df78e8a 100644 --- a/src/libvirt.c +++ b/src/libvirt.c @@ -5562,7 +5562,9 @@ virDomainMigrateToURI (virDomainPtr domain, goto error; } else { /* Cannot do a migration with only the perform step */ - virLibConnError(VIR_ERR_NO_SUPPORT, __FUNCTION__); + virLibConnError(VIR_ERR_OPERATION_INVALID, "%s", + _("direct migration is not supported by the" + " connection driver")); goto error; } } @@ -5696,7 +5698,9 @@ virDomainMigrateToURI2(virDomainPtr domain, goto error; } else { /* Cannot do a migration with only the perform step */ - virLibConnError(VIR_ERR_NO_SUPPORT, __FUNCTION__); + virLibConnError(VIR_ERR_OPERATION_INVALID, "%s", + _("direct migration is not supported by the" + " connection driver")); goto error; } } diff --git a/tools/virsh.pod b/tools/virsh.pod index ae00622..4bddf15 100644 --- a/tools/virsh.pod +++ b/tools/virsh.pod @@ -990,6 +990,9 @@ is implicitly enabled when supported by the hypervisor, but can be explicitly used to reject the migration if the hypervisor lacks change protection support.

[libvirt] Libvirt iSCSI APIs
by Ata Bohra 13 Jul '12

13 Jul '12

Hi All, I am interested in extending libvirt APIs to support iSCSI operations such as: add/remove targets, list targets, list remote LUNs, rescan luns etc. The intention is to provide an interface that external programs can hook to manage iSCSI storage devices on a given hypervisor(I would be adding interfaces for ESX first). Looking at the libvirt.c interface for storage driver I'm unable find routines that can be overridden for specific hypervisor. Googling lead to a nice blog presentation that provisions VMs on remote LUN(s) for KVM but uses virish. (http://berrange.com/tags/iscsi/) My question is; is this as per design not to expose iSCSI related APIs? Will an extention to libvirt.c (_virStorageDriver) so that every hypervisor can implement it is acceptable? Please correct me if I am missing something serious here. Thanks! Ata

[libvirt] [PATCH] Fix daemon auto-spawning
by Christophe Fergeau 12 Jul '12

12 Jul '12

Commit 32a9aac switched libvirt to use the XDG base directories to locate most of its data/config. In particular, the per-user socket for qemu:///session is now stored in the XDG runtime directory. This directory is located by looking at the XDG_RUNTIME_DIR environment variable, with a fallback to ~/.cache/libvirt if this variable is not set. When the daemon is autospawned because a client application wants to use qemu:///session, the daemon is ran in a clean environment which does not contain XDG_RUNTIME_DIR. It will create its socket in ~/.cache/libvirt. If the client application has XDG_RUNTIME_DIR set, it will not look for the socket in the fallback place, and will fail to connect to the autospawned daemon. This patch adds XDG_RUNTIME_DIR to the daemon environment before auto-starting it. I've done this in virNetSocketForkDaemon rather than in virCommandAddEnvPassCommon as I wasn't sure we want to pass these variables to other commands libvirt spawns. XDG_CACHE_HOME and XDG_CONFIG_HOME are also added to the daemon env as it makes use of those as well. --- src/rpc/virnetsocket.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/src/rpc/virnetsocket.c b/src/rpc/virnetsocket.c index 0b32ffe..08dfbb0 100644 --- a/src/rpc/virnetsocket.c +++ b/src/rpc/virnetsocket.c @@ -97,6 +97,9 @@ static int virNetSocketForkDaemon(const char *binary) NULL); virCommandAddEnvPassCommon(cmd); + virCommandAddEnvPass(cmd, "XDG_CACHE_HOME"); + virCommandAddEnvPass(cmd, "XDG_CONFIG_HOME"); + virCommandAddEnvPass(cmd, "XDG_RUNTIME_DIR"); virCommandClearCaps(cmd); virCommandDaemonize(cmd); ret = virCommandRun(cmd, NULL); -- 1.7.10.4

[libvirt] dnsmasq SRV/TXT RR and Host xml parsing upgrade and bug fix
by Guannan Ren 12 Jul '12

12 Jul '12

The set of patches aims to three kind of jobs. First, for SRV RR, in order to strictly comform to RFC 2782, the patch changed and upgraded codes in following parts. The format of SRV RR: _Service._Proto.Name TTL Class SRV Priority Weight Port Target 1,The protocol and service labels are prepended with an underscore. e.g: _ldap._tcp.example.com 2,The range of Port,Priority,Weight is 0-65535. 3,A Target of "." means that the service is decidedly not available at this domain. Also, trying to invoke dnsmasq command line based on its manpage. --srv-host=<_service>.<_prot>.[<domain>],[<target>[,<port>[,<priority>[,<weight>]]]] _service and protocol are mandatory options. The reset of them are optional. When the target is not given in dnsmasq, it comform to the third item above. For TXT RR, we changed the text field from mandatory to optional based on dnsmasq manpage: --txt-record=<name>[[,<text>],<text>] Second, changed the way of dns element as well as its children elements parsing via virXPathNodeSet(). It has advantages when multiple children elements there is. Third, fixed related bug and unexposed bugs https://bugzilla.redhat.com/show_bug.cgi?id=836326

[libvirt] [PATCHv2] fix failure when building with --disable-debug

When building with --disable-debug, VIR_DEBUG expands to a nop. But parameters to VIR_DEBUG can be variables that are passed only to VIR_DEBUG. In the case the building system complains about unused variables. --- cfg.mk | 2 ++ src/util/logging.h | 8 +++++++- 2 files changed, 9 insertions(+), 1 deletion(-) diff --git a/cfg.mk b/cfg.mk index 7664d5d..6e036fb 100644 --- a/cfg.mk +++ b/cfg.mk @@ -750,6 +750,8 @@ $(srcdir)/src/remote/remote_client_bodies.h: $(srcdir)/src/remote/remote_protoco $(MAKE) -C src remote/remote_client_bodies.h # List all syntax-check exemptions: +exclude_file_name_regexp--sc_avoid_attribute_unused_in_header = ^src/util/logging\.h$$ + exclude_file_name_regexp--sc_avoid_strcase = ^tools/virsh\.c$$ _src1=libvirt|fdstream|qemu/qemu_monitor|util/(command|util)|xen/xend_internal|rpc/virnetsocket|lxc/lxc_controller diff --git a/src/util/logging.h b/src/util/logging.h index 70318d0..7cc5823 100644 --- a/src/util/logging.h +++ b/src/util/logging.h @@ -34,8 +34,14 @@ # define VIR_DEBUG_INT(category, f, l, ...) \ virLogMessage(category, VIR_LOG_DEBUG, f, l, 0, __VA_ARGS__) # else +/** + * virLogEatParam: + * + * Do nothing but eat parameters. + */ +static inline void virLogEatParam(void *unused ATTRIBUTE_UNUSED, ...) {} # define VIR_DEBUG_INT(category, f, l, ...) \ - do { } while (0) + virLogEatParam((void*)category, f, l, __VA_ARGS__) # endif /* !ENABLE_DEBUG */ # define VIR_INFO_INT(category, f, l, ...) \ -- 1.7.10.2

[libvirt] [PATCH 0/6] Add usb controller model="none"
by Peter Krempa 12 Jul '12

12 Jul '12

This series adds support for completely disabling USB bus for a host if a user requires this. For this to work a new USB controller model "none" was added that removes the USB bus. The controller is added in patches 2-4. Patch 1 cleans up some nits (and is not necessary) and patches 5 and 6 tweak qemuxml2argvtest and add tests to check the new controller. Peter Krempa (6): maint: Clean up coding style domain_conf: Add USB controler model "none" domain_conf: Add helpers to verify if device configuration is valid qemu: Add support for "none" USB controller tests: Add support for cathing domain XML parsing errors tests: Add tests to check the new USB "none" controller docs/schemas/domaincommon.rng | 1 + src/conf/domain_conf.c | 121 +++++- src/conf/domain_conf.h | 6 + src/libvirt_private.syms | 2 + src/qemu/qemu_command.c | 29 +- src/qemu/qemu_driver.c | 13 +- .../qemuxml2argvdata/qemuxml2argv-usb-none-hub.xml | 19 + .../qemuxml2argv-usb-none-other.xml | 19 + .../qemuxml2argv-usb-none-usbtablet.xml | 21 + tests/qemuxml2argvdata/qemuxml2argv-usb-none.args | 5 + tests/qemuxml2argvdata/qemuxml2argv-usb-none.xml | 16 + tests/qemuxml2argvtest.c | 507 ++++++++++---------- 12 files changed, 491 insertions(+), 268 deletions(-) create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-usb-none-hub.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-usb-none-other.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-usb-none-usbtablet.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-usb-none.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-usb-none.xml -- 1.7.8.6

[libvirt] CPU tuning in containers
by Sukadev Bhattiprolu 11 Jul '12

11 Jul '12

Following section indicates that CPU tuning with <period> and <quota> tags are only supported for QEMU http://libvirt.org/formatdomain.html#elementsCPUTuning I see this commit in libvirt.git: commit d9724a81b3c53a40f45bf76067a976cce73ed278 Author: Daniel P. Berrange <berrange(a)redhat.com> Date: Thu Nov 10 12:16:26 2011 +0000 Add support for CPU quota/period to LXC driver and the code seems to be included in libvirt-0.9.10-21.el6. I have not had a chance to try on latest libvirt yet, but is it just that the CPUTuning section on the above wiki needs an update ?

[libvirt] [PATCH v4 0/7] file descriptor passing using pass-fd
by Corey Bryant 11 Jul '12

11 Jul '12

libvirt's sVirt security driver provides SELinux MAC isolation for Qemu guest processes and their corresponding image files. In other words, sVirt uses SELinux to prevent a QEMU process from opening files that do not belong to it. sVirt provides this support by labeling guests and resources with security labels that are stored in file system extended attributes. Some file systems, such as NFS, do not support the extended attribute security namespace, and therefore cannot support sVirt isolation. A solution to this problem is to provide fd passing support, where libvirt opens files and passes file descriptors to QEMU. This, along with SELinux policy to prevent QEMU from opening files, can provide image file isolation for NFS files stored on the same NFS mount. This patch series adds the pass-fd QMP monitor command, which allows an fd to be passed via SCM_RIGHTS, and returns the received file descriptor. Support is also added to the block layer to allow QEMU to dup the fd when the filename is of the /dev/fd/X format. This is useful if MAC policy prevents QEMU from opening specific types of files. One nice thing about this approach is that no new SELinux policy is required to prevent open of NFS files (files with type nfs_t). The virt_use_nfs boolean type simply needs to be set to false, and open will be prevented (and dup will be allowed). For example: # setsebool virt_use_nfs 0 # getsebool virt_use_nfs virt_use_nfs --> off Corey Bryant (7): qemu-char: Add MSG_CMSG_CLOEXEC flag to recvmsg qapi: Convert getfd and closefd qapi: Add pass-fd QMP command qapi: Re-arrange monitor.c functions block: Prevent /dev/fd/X filename from being detected as floppy block: Convert open calls to qemu_open osdep: Enable qemu_open to dup pre-opened fd block/raw-posix.c | 22 +++++----- block/raw-win32.c | 4 +- block/vdi.c | 5 ++- block/vmdk.c | 21 ++++------ block/vpc.c | 2 +- block/vvfat.c | 21 +++++----- cutils.c | 26 +++++++++--- dump.c | 3 +- hmp-commands.hx | 6 +-- hmp.c | 18 ++++++++ hmp.h | 2 + main-loop.c | 6 +-- migration-fd.c | 2 +- monitor.c | 120 ++++++++++++++++++++++++++++++++--------------------- monitor.h | 2 +- net.c | 6 ++- osdep.c | 91 ++++++++++++++++++++++++++++++++++++++++ qapi-schema.json | 71 +++++++++++++++++++++++++++++++ qemu-char.c | 2 +- qemu-common.h | 2 +- qmp-commands.hx | 56 ++++++++++++++++++++++--- 21 files changed, 378 insertions(+), 110 deletions(-) -- 1.7.10.2

[libvirt] [PATCH] Support creation of sparse LVM volumes
by Daniel P. Berrange 11 Jul '12

11 Jul '12

From: "Daniel P. Berrange" <berrange(a)redhat.com> When calling 'lvcreate' if specifying both the '-L' and '--virtualsize' options, the latter will be treated as the capacity and the former as the allocation. This can be used to support sparse volume creation.

[libvirt] Problem setting CPU topology
by Zeeshan Ali (Khattak) 11 Jul '12

11 Jul '12

Hi, I'm trying to set exact CPU topology to qemu-kvm domains to match host's topology. In my case, host topology is: 1 socket, 2 cores and 2 threads. If I set the XML like this: <domain type='kvm'> .. <vcpu placement='static'>4</vcpu> <os> <type arch='i686' machine='pc-0.15'>hvm</type> <boot dev='hd'/> </os> <cpu mode='host-model'> <model fallback='allow'/> <topology sockets='1' cores='2' threads='2'/> </cpu> .. The qemu commandline launched for this domain looks like this: /usr/bin/qemu-kvm -name fedora17-2 -S -M pc-0.15 -cpu core2duo,+lahf_lm,+rdtscp,+aes,+popcnt,+sse4.2,+sse4.1,+pdcm,+xtpr,+cx16,+tm2,+est,+smx,+vmx,+ds_cpl,+dtes64,+pclmuldq,+pbe,+tm,+ht,+ss,+acpi,+ds -enable-kvm -m 1152 -smp 4,sockets=1,cores=2,threads=2 -uuid c573342b-2876-05b8-098e-6d5314cab062 -nodefconfig -nodefaults -chardev socket,id=charmonitor,path=/home/zeenix/.config/libvirt/qemu/lib/fedora17-2.monitor,server,nowait -mon chardev=charmonitor,id=monitor,mode=control -rtc base=utc,driftfix=slew -no-kvm-pit-reinjection -no-shutdown -no-acpi -device piix3-usb-uhci,id=usb,bus=pci.0,addr=0x1.0x2 -device virtio-serial-pci,id=virtio-serial0,bus=pci.0,addr=0x5 -drive file=/home/zeenix/.local/share/gnome-boxes/images/fedora17-2,if=none,id=drive-virtio-disk0,format=qcow2,cache=none -device virtio-blk-pci,scsi=off,bus=pci.0,addr=0x6,drive=drive-virtio-disk0,id=virtio-disk0,bootindex=1 -drive file=/extra-data/ISOs/Fedora-17-i686-Live-Desktop.iso,if=none,id=drive-ide0-1-0,readonly=on,format=raw -device ide-cd,bus=ide.1,unit=0,drive=drive-ide0-1-0,id=ide0-1-0 -netdev user,id=hostnet0 -device rtl8139,netdev=hostnet0,id=net0,mac=52:54:00:21:6f:6e,bus=pci.0,addr=0x3 -chardev pty,id=charserial0 -device isa-serial,chardev=charserial0,id=serial0 -chardev spicevmc,id=charchannel0,name=vdagent -device virtserialport,bus=virtio-serial0.0,nr=1,chardev=charchannel0,id=channel0,name=com.redhat.spice.0 -device usb-tablet,id=input0 -spice port=5900,addr=127.0.0.1,disable-ticketing -vga qxl -global qxl-vga.vram_size=67108864 -device AC97,id=sound0,bus=pci.0,addr=0x4 -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x7 Despite the '-smp 4,sockets=1,cores=2,threads=2', I see only 1 CPU reported by '/proc/cpuinfo' in the guest F17 live.

[libvirt] [PATCHv3 0/5] Virtio support for S390

[libvirt] [PATCHv2] openvz: Handle domain obj hash map errors
by Guido Günther 11 Jul '12

This makes the driver fail with a clear error message in case of UUID collisions (for example if somebody copied a container configuration without updating the UUID) and also raises an error on other hash map failures. OpenVZ itself doesn't complain about duplicate UUIDs since this parameter is only used by libvirt. --- This version adds an extra check for hash collisions and keeps the generic failure message for all other errors in virHashAddEntry.

[libvirt] [PATCH] Fix /domain/features setting in qemuParseCommandLine
by Christophe Fergeau 11 Jul '12

11 Jul '12

Commit 5e6ce1 moved down detection of the ACPI feature in qemuParseCommandLine. However, when ACPI is detected, it clears all feature flags in def->features to only set ACPI. This used to be fine because this was the first place were def->features was set, but after the move this is no longer necessarily true because this block comes before the ACPI check: if (strstr(def->emulator, "kvm")) { def->virtType = VIR_DOMAIN_VIRT_KVM; def->features |= (1 << VIR_DOMAIN_FEATURE_PAE); } Since def is allocated in qemuParseCommandLine using VIR_ALLOC, we can always use |= when modifying def->features --- This is an issue I noticed while reading this code for other reasons, I have only compile-tested it and I'm not sure how to test it.

[libvirt] [PATCH 00/13] Support hypervisor-threads-pin in vcpupin.
by tangchen 10 Jul '12

10 Jul '12

Hi~ Users can use vcpupin command to bind a vcpu thread to a specific physical cpu. But besides vcpu threads, there are alse some other threads created by qemu (known as hypervisor threads) that could not be explicitly bound to physical cpus. The first 3 patches are from Wen Congyang, which implement Cgroup for differrent hypervisors. The other 10 patches implemented hypervisor threads binding, in two ways: 1) Use sched_setaffinity() function; 2) In cpuset cgroup. A new xml element is introduced, and vcpupin command is improved, see below. 1. Introduce new xml elements: <cputune> ...... <hypervisorpin cpuset='1'/> </cputune> 2. Improve vcpupin command to support hypervisor threads binding. For example, vm1 has the following configuration: <cputune> <vcpupin vcpu='1' cpuset='1'/> <vcpupin vcpu='0' cpuset='0'/> <hypervisorpin cpuset='1'/> </cputune> 1) query all threads pining # vcpupin vm1 VCPU: CPU Affinity ---------------------------------- 0: 0 1: 1 Hypervisor: CPU Affinity ---------------------------------- *: 1 2) query hypervisor threads pining only # vcpupin vm1 --hypervisor Hypervisor: CPU Affinity ---------------------------------- *: 1 3) change hypervisor threads pining # vcpupin vm1 --hypervisor 0-1 # vcpupin vm1 --hypervisor Hypervisor: CPU Affinity ---------------------------------- *: 0-1 # taskset -p 397 pid 397's current affinity mask: 3 Note: If users want to pin a vcpu thread to pcpu, --vcpu option could no longer be omitted. Tang Chen (10): Enable cpuset cgroup and synchronous vcpupin info to cgroup. Support hypervisorpin xml parse. Introduce qemuSetupCgroupHypervisorPin and synchronize hypervisorpin info to cgroup. Add qemuProcessSetHypervisorAffinites and set hypervisor threads affinities Introduce virDomainHypervisorPinAdd and virDomainHypervisorPinDel functions Introduce qemudDomainPinHypervisorFlags and qemudDomainGetHypervisorPinInfo in qemu driver. Introduce remoteDomainPinHypervisorFlags and remoteDomainGetHypervisorPinInfo functions in remote driver. Introduce remoteDispatchDomainPinHypervisorFlags and remoteDispatchDomainGetHypervisorPinInfo functions. Introduce virDomainPinHypervisorFlags and virDomainGetHypervisorPinInfo functions. Improve vcpupin to support hypervisorpin dynically.

[libvirt] Bug report 826704 - sanlock releases all resources on virsh detach-disk
by Frido Roose 10 Jul '12

10 Jul '12

Hello, I logged a bug about using virsh detach-disk cleaning up all sanlock resources for the domain instead of only the device in question. After a quick look into the code, I think a new method similar to virLockManagerSanlockAddResource is needed in case of detaching a disk from the domain, like e.g. virLockManagerSanlockDelResource (…). Now it looks like virLockManagerSanlockRelease is called, which releases all resources: if ((rv = sanlock_release(-1, priv->vm_pid, SANLK_REL_ALL, 0, NULL)) < 0) { virsh detach-disk should then call virLockManagerSanlockDelResource for the given resource imo. Any thoughts about this or why it is implemented like this? -- Frido Roose

[libvirt] ANNOUNCE: virt-manager 0.9.2 and virtinst 0.600.2 released
by Cole Robinson 09 Jul '12

09 Jul '12

I'm happy to announce two new releases: virt-manager 0.9.2: virt-manager is a desktop application for managing KVM and Xen virtual machines via libvirt. virtinst 0.600.2: virtinst is a collection of command line tools for provisioning libvirt virtual machines, including virt-install and virt-clone. The releases can be downloaded from: http://virt-manager.org/download.html The direct download links are: http://virt-manager.org/download/sources/virt-manager/virt-manager-0.9.2.ta… http://virt-manager.org/download/sources/virtinst/virtinst-0.600.2.tar.gz The virt-manager release includes: - Convert to gtkbuilder: UI can now be edited with modern glade tool - virt-manager no longer runs on RHEL5, but can manage a remote RHEL5 host - Option to configure spapr net and disk devices for pseries (Li Zhang) - Many bug fixes and improvements The virtinst release includes: - virt-install: New --memballoon option (Eiichi Tsukata) - virt-install: Improved qemu/kvm pseries support (Li Zhang, Qing Lin) - virt-install: Support setting BIOS path using -boot loader=PATH - Various bug fixes and improvements Also, unless there are serious snags, the next virt-manager release will have some major organizational changes: port to GTK3, virtinst will no longer be a public API, merging virtinst and virt-manager git repos, maybe even converting to python3. While this will facilitate a ton of future improvements, the downside is that a much more recent distro will be required to run virt-manager. More info forthcoming on virt-tools-list Thanks, Cole

[libvirt] [RFC 0/5] block: File descriptor passing using -open-hook-fd
by Stefan Hajnoczi 09 Jul '12

09 Jul '12

Libvirt can take advantage of SELinux to restrict the QEMU process and prevent it from opening files that it should not have access to. This improves security because it prevents the attacker from escaping the QEMU process if they manage to gain control. NFS has been a pain point for SELinux because it does not support labels (which I believe are stored in extended attributes). In other words, it's not possible to use SELinux goodness on QEMU when image files are located on NFS. Today we have to allow QEMU access to any file on the NFS export rather than restricting specifically to the image files that the guest requires. File descriptor passing is a solution to this problem and might also come in handy elsewhere. Libvirt or another external process chooses files which QEMU is allowed to access and provides just those file descriptors - QEMU cannot open the files itself. This series adds the -open-hook-fd command-line option. Whenever QEMU needs to open an image file it sends a request over the given UNIX domain socket. The response includes the file descriptor or an errno on failure. Please see the patches for details on the protocol. The -open-hook-fd approach allows QEMU to support file descriptor passing without changing -drive. It also supports snapshot_blkdev and other commands that re-open image files. Anthony Liguori <aliguori(a)us.ibm.com> wrote most of these patches. I added a demo -open-hook-fd server and added some small fixes. Since Anthony is traveling right now I'm sending the RFC for discussion. Anthony Liguori (3): block: add open() wrapper that can be hooked by libvirt block: add new command line parameter that and protocol description block: plumb up open-hook-fd option Stefan Hajnoczi (2): osdep: add qemu_recvmsg() wrapper Example -open-hook-fd server block.c | 107 ++++++++++++++++++++++++++++++++++++++ block.h | 2 + block/raw-posix.c | 18 +++---- block/raw-win32.c | 2 +- block/vdi.c | 2 +- block/vmdk.c | 6 +-- block/vpc.c | 2 +- block/vvfat.c | 4 +- block_int.h | 12 +++++ osdep.c | 46 +++++++++++++++++ qemu-common.h | 2 + qemu-options.hx | 42 +++++++++++++++ test-fd-passing.c | 147 +++++++++++++++++++++++++++++++++++++++++++++++++++++ vl.c | 3 ++ 14 files changed, 378 insertions(+), 17 deletions(-) create mode 100644 test-fd-passing.c -- 1.7.10

[libvirt] FYI: CVE-2012-3386 - vulnerability of 'make distcheck'
by Eric Blake 09 Jul '12

09 Jul '12

Libvirt is vulnerable to an automake security hole; anyone that runs 'make distcheck' on any existing libvirt release tarball risks a local exploit that can take advantage of world-writable permissions to inject the operation of attacker-controlled code under the capabilities of the developer testing the package. This security hole can be mitigated by either avoiding the use of 'make distcheck', or by setting a restrictive umask (such as 022) before running 'make distcheck'. Since few people beyond developers tend to run 'make distcheck', I'm not too worried about pushing out a new libvirt tarball any sooner than the regular release cycle. But we should definitely upgrade to the latest gnulib (it adds a syntax check to validate whether the vulnerability still exists), and ensure that the release of libvirt 0.10.0, as well as the next maintenance releases of v0.9.{6,11}-maint, have been built with patched automake. -- Eric Blake eblake(a)redhat.com +1-919-301-3266 Libvirt virtualization library http://libvirt.org

[libvirt] [PATCH 0/3] fix segfault when trying to discover netfs pool sources
by Peter Krempa 09 Jul '12

09 Jul '12

https://bugzilla.redhat.com/show_bug.cgi?id=837470 There's a regression in the netfs detection code that causes a double-free error when the detection fails. After fixing the regression another one appeared connected with adding multiple pool source hosts. This series fixes both problems.

[libvirt] numa query
by kapil jain 09 Jul '12

09 Jul '12

Hi, I have a host machine which contains 4 numa nodes each with 2 GB memory and 4 cpus. I am using qem-kvm hypervisor. I am trying to create a guest with the similar topology (4 numa nodes, with only 2 vcpus and 1 GB memory) as host. Each vcpu is 1-1 pinned to physical cpus(i.e. guest{socket0 cpu0} is pinned to host{socket0 cpu0). But one critical requirement is that one guest socket should not have memory from two host sockets to avoid numa access completely. With the current constructs of numa/topology I am able to create the guest. But memory is not mapped as socket 1-1. numatune is not helping. Please suggest a possible way. Thanks, Kapil

[libvirt] [PATCH 00/15] Major refactor of LXC controller code
by Daniel P. Berrange 09 Jul '12

09 Jul '12

The LXC controller code (libvirt_lxc binary) has grown rather large and complicated over time. One of the particularly bad problems is that there is no single store of global state. The results is that methods are passing around huge lists of parameters and it becomes unclear who is responsible for cleaning up state on failure. Although they are harmless in this context, there are many FDs which are leaked in the normal shutdown path. This series refactors everything so that a virLXCControllerPtr object holds all global state. The final patch also switches over to using the virNetServer APIs for the client/server monitor socket handling. There should be no functional change in this series, but it prepares the way for the next fun bit which is to introduce a full RPC protocol between libvirtd & libvirt_lxc. This will enable us to provide a bunch of interesting new APIs that are desired for LXC. Don't be put off by the large patch series - each change is fairly small & self-contained, with primarily just renaming of variables and funtions daemon/libvirtd.c | 3 daemon/remote.c | 3 daemon/remote.h | 3 src/Makefile.am | 41 - src/libvirt_private.syms | 1 src/lxc/lxc_container.c | 10 src/lxc/lxc_container.h | 2 src/lxc/lxc_controller.c | 1250 +++++++++++++++++++++-------------------------- src/rpc/virnetserver.c | 120 ++-- src/rpc/virnetserver.h | 6 src/util/virfile.c | 138 +++++ src/util/virfile.h | 3 12 files changed, 819 insertions(+), 761 deletions(-)

[libvirt] [PATCH 0/3] esx: Storage volume up- and download
by Matthias Bolte 08 Jul '12

08 Jul '12

I started the download part and the stream driver quite a while ago but stopped and put it aside as I realized that the storage volume API up- and download functions assume one file per volume. This is a problem with ESX as a VMDK can consist of two files. To solve this now I added two new flags: METADATA and CONTENT. With this flags the user can specify which part of such a volume to transfer. See patch 3/3 for more details. Matthias

Re: [libvirt] [fedora-virt] qemu 1.1.0 in Rawhide, and planned backport to F17 (was: Re: Upgrading qemu to 1.1 in rawhide)
by Richard W.M. Jones 06 Jul '12

06 Jul '12

[On the topic of qemu 1.1.0 in Fedora 17] I'm seeing some very peculiar problems with virt-install that might be due to libvirt. Is libvirt in F17 too old for qemu 1.1.0? ------- (1) Just installing qemu-system-x86 isn't enough for libvirt to recognize any hypervisors: ERROR Host does not support any virtualization options virsh capabilities doesn't show any <guest> section at all. Of course qemu-kvm *is* installed and working. Solution: install the qemu meta-package. Unfortunately that means I have to have qemu-system-{cris,sh4,arm,mips} which I didn't want.
