[libvirt] [PATCH] conf: Generate agent socket path if missing
by Michal Privoznik 16 Feb '13

16 Feb '13

It's not desired to force users imagine path for a socket they are not even supposed to connect to. On the other hand, we already have a release where the qemu agent socket path is exposed to XML, so we cannot silently drop it from there. The new path is generated in form: $LOCALSTATEDIR/lib/libvirt/qemu/$domain.agent --- This makes the qemu agent to be generated at domain startup phase. So until that, we generate XML without any path, e.g.: <channel type='unix'> <source mode='connect'/> <target type='virtio' name='org.qemu.guest_agent.0'/> <address type='virtio-serial' controller='0' bus='0' port='1'/> </channel> The other possibility is to generate path during XML parse phase, however this expose something we are lacking for years - callbacks to fill in default values for not configured ones. The aim so to make libvirt accept this snippet as valid qemu agent config: <channel type='unix'> <target type='virtio' name='org.qemu.guest_agent.0'/> </channel> src/conf/domain_conf.c | 37 ++++++++++++++++++++----------------- src/qemu/qemu_process.c | 30 ++++++++++++++++++++++++++++-- 2 files changed, 48 insertions(+), 19 deletions(-) diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index 7a2b012..6245fec 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -6038,7 +6038,10 @@ virDomainChrSourceDefParseXML(virDomainChrSourceDefPtr def, break; case VIR_DOMAIN_CHR_TYPE_UNIX: - if (path == NULL) { + /* path is not required in special case of qemu guest agent */ + if (path == NULL && + chr_def->targetType != VIR_DOMAIN_CHR_CHANNEL_TARGET_TYPE_VIRTIO && + STRNEQ(chr_def->target.name, "org.qemu.guest_agent.0")) { virReportError(VIR_ERR_INTERNAL_ERROR, "%s", _("Missing source path attribute for char device")); goto error; @@ -6135,7 +6138,6 @@ virDomainChrDefParseXML(virCapsPtr caps, char *type = NULL; const char *nodeName; virDomainChrDefPtr def; - int remaining; bool seenTarget = false; if (!(def = virDomainChrDefNew())) @@ -6159,29 +6161,28 @@ virDomainChrDefParseXML(virCapsPtr caps, } cur = node->children; - remaining = virDomainChrSourceDefParseXML(&def->source, cur, flags, - def, ctxt, - vmSeclabels, nvmSeclabels); - if (remaining < 0) - goto error; - if (remaining) { - while (cur != NULL) { - if (cur->type == XML_ELEMENT_NODE) { - if (xmlStrEqual(cur->name, BAD_CAST "target")) { - seenTarget = true; - if (virDomainChrDefParseTargetXML(caps, vmdef, def, cur) < 0) { - goto error; - } + while (cur != NULL) { + if (cur->type == XML_ELEMENT_NODE) { + if (xmlStrEqual(cur->name, BAD_CAST "target")) { + seenTarget = true; + if (virDomainChrDefParseTargetXML(caps, vmdef, def, cur) < 0) { + goto error; } + break; } - cur = cur->next; } + cur = cur->next; } if (!seenTarget && ((def->targetType = virDomainChrDefaultTargetType(caps, vmdef, def->deviceType)) < 0)) goto cleanup; + if (virDomainChrSourceDefParseXML(&def->source, node->children, + flags, def, ctxt, + vmSeclabels, nvmSeclabels) < 0) + goto error; + if (def->source.type == VIR_DOMAIN_CHR_TYPE_SPICEVMC) { if (def->targetType != VIR_DOMAIN_CHR_CHANNEL_TARGET_TYPE_VIRTIO) { virReportError(VIR_ERR_CONFIG_UNSUPPORTED, "%s", @@ -13307,10 +13308,12 @@ virDomainChrSourceDefFormat(virBufferPtr buf, break; case VIR_DOMAIN_CHR_TYPE_UNIX: + virBufferAsprintf(buf, " <source mode='%s'", def->data.nix.listen ?

[libvirt] [hyperv]: Connection failure
by Ata Bohra 16 Feb '13

16 Feb '13

Hi Everyone, I installed a HyperV server and trying to connect to it using libvirt. As suggested by libvirt driver wiki (http://libvirt.org/drvhyperv.html) I've enabled Basic authentication on the server (and also enabled HTTP connection request for debugging purpose). Even after all this configuration, on connection I get error as: ---------------Enter Administrator's password for 10.y.y.y: xxxxxx 2013-02-14 00:02:25.122+0000: 6825: info : libvirt version: 1.0.2 2013-02-14 00:02:25.122+0000: 6825: error : hypervDebugHandler:1444 : openwsman error: NULL response libvir: Hyper-V Driver error : internal error Transport error during enumeration: Could not connect (7) Failed to open connection libvir: error : invalid connection pointer in virConnectGetHostname Host name: (null) libvir: error : invalid connection pointer in virConnectClose ------------------------------ Hyper-V server configuration looks like:xxx> winrm get winrm/config/serviceServiceROOTSDDL = <long string>MaxConnectionOperations = 4294967295MaxConnectionOperationsPerUser = 1500MaxConnectionTimeoutms = 240000MaxConnections = 300MaxPacketRetrievalTimeSeconds = 120AllowUnencrypted = trueAuth Basic = true ........AllowRemoteAccess = true ------------------------------ I'm have libvirt on ubuntu (3.2.0-37-generic) and openwsman is 2.2.3-oubuntu4 version.

[libvirt] [PATCH] qemu: handle not supported writable devices
by Philipp Hahn 15 Feb '13

15 Feb '13

If the running VM contains a writable raw image, creating snapshot fails internally in QEMU, but the error is not detected by libvirt. Success is still reported to the user, who will see the snapshot in libvirt, even they are NOT created by qemu. virsh # qemu-monitor-command --hmp winxp-1 savevm \"test\" Device 'drive-fdc0-0-0' is writable but does not support snapshots. virsh # snapshot-create-as winxp-1 test Domain snapshot test created Since there is no QMP command in QEMU, libvirtd sends a HMP command to the running QEMU and parses the returned text. There only the following 4 strings are detected as errors: src/qemu/qemu_monitor_text.c:2822 # qemuMonitorTextCreateSnapshot() > "Error while creating snapshot" > "No block device can accept snapshots" > "Could not open VM state file" > "Error" + "while writing VM" Since none of them match the above message, libvirt thinks the command succeeded. Add "does not support snapshots" as an additional error condition.
