[libvirt] 0.7.5 errors in configure script
by Avi Weit 18 Jan '10

18 Jan '10

Hi, I am using Ubuntu 9.10 and downloaded and extracted libvirt.0.7.5. I have issued: ./configure --prefix=$HOME/usr --without-xen but I get: You must install device-mapper-devel/libdevmapper >= 1.0.0 to compile libvirt Below is a snippet of the final configure output: checking for showmount... no checking for pvcreate... no checking for vgcreate... no checking for lvcreate... no checking for pvremove... no checking for vgremove... no checking for lvremove... no checking for vgchange... no checking for vgscan... no checking for pvs... no checking for vgs... no checking for lvs... no checking for iscsiadm... no checking for DEVMAPPER... no checking libdevmapper.h usability... no checking libdevmapper.h presence... no checking for libdevmapper.h... no checking for dm_task_run in -ldevmapper... no configure: error: You must install device-mapper-devel/libdevmapper >= 1.0.0 to compile libvirt /dev/mapper exists on the system. Any help is appreciated. Thanks, - Avi

[libvirt] [PATCH 00/34] Add device addressing and disk controller support
by Daniel P. Berrange 18 Jan '10

18 Jan '10

This series is a merge of two previous series I posted http://www.redhat.com/archives/libvir-list/2009-December/msg00232.html http://www.redhat.com/archives/libvir-list/2009-December/msg00392.html It accomplishes quite a lot of things, having major impact on the QEMU driver, hopefully all in a postive way :-) In particular it does * Add standard XML syntax for addressing of PCI devices, and disk drives * Add support for disk controllers as a managed device in XML * Add support for disk controller hotplug/unplug * Convert everything over to use QEMU's -device flag where available * Add PCI addressing when using -device * Introduce a way to give every device a unique 'alias' name in the XML format I can't promise it works perfectly, but i've done quite alot of positive testing with it now & believe all the back comptability stuff is working right.

[libvirt] [PATCH] storage_backend_fs.c: do not ignore probe failure
by Jim Meyering 18 Jan '10

18 Jan '10

When virStorageBackendProbeTarget fails, it returns -1 or -2. The two uses below obviously intended to handle those cases differently, but due to a wrong comparison, they always treated a "real" (e.g., open) failure (-1) just like an ignorable "wrong file type" failure (-2). FYI, coverity reported that the "goto cleanup" statement was unreachable, which was true in each case, but hardly the real problem. >From c9ba79daf124afbab351741192bbaf7110a199dd Mon Sep 17 00:00:00 2001 From: Jim Meyering <meyering(a)redhat.com> Date: Mon, 18 Jan 2010 10:34:53 +0100 Subject: [PATCH] storage_backend_fs.c: do not ignore probe failure * src/storage/storage_backend_fs.c (virStorageBackendFileSystemRefresh): Correct two error-handling bugs.

[libvirt] [PATCH] secret_driver.c: remove dead cleanup code
by Jim Meyering 18 Jan '10

18 Jan '10

Here's another example of appropriate use of assert. The while loop removed below is currently guaranteed never to be executed, since "list" is always NULL at that point. However, you can argue that simply removing the loop is a little risky: what if someone changes things to "goto cleanup" before "list" reaches the final NULL? That's why I added the assertion: to catch the potential (albeit unlikely) future coding error. It would be a shame to include "real" run-time code to detect a situation like that that will probably never arise. And if you do, technically you'd have to document that the function would return some sort of error code if a developer changes its guts in a way that violates this invariant. That would be nonsensical. >From 6baa2b0b8f9963fa60ff0946afcefd57586e2720 Mon Sep 17 00:00:00 2001 From: Jim Meyering <meyering(a)redhat.com> Date: Mon, 18 Jan 2010 10:46:57 +0100 Subject: [PATCH] secret_driver.c: remove dead cleanup code * src/secret/secret_driver.c (loadSecrets): Remove dead code after "cleanup:".

[libvirt] [PATCH] Use closest CPU model when decoding from CPUID
by Jiri Denemark 18 Jan '10

18 Jan '10

Current implementation of x86Decode() used for CPUID -> model+features translation does not always select the closest CPU model. When walking through all models from cpu_map.xml the function considers a new candidate as a better choice than a previously selected candidate only if the new one is a superset of the old one. In case the new candidate is closer to host CPU but lacks some feature comparing to the old candidate, the function does not choose well. This patch changes the algorithm so that the closest model is always selected. That is, the model which requires the lowest number of additional features to describe host CPU.

Always use AC_HELP_STRING for the help text for options at ./configure, so that the output is properly aligned. Use proper quadrigraphs for outputting the brackets. Always use autoconf-style [default=$foo] output to state the default, both where it was stated before and where it wasn't.

[libvirt] [PATCH 0/4] A bit of configure clear-up
by Diego Elio Pettenò 18 Jan '10

18 Jan '10

Since on the whole it seems like the configure could see some cleanup, as it seem to use lots of older constructs and repeated code, I tried doing some basic cleaning. My changes also require autoconf-2.63… it could be something older as well, but 2.63 is new enough I'd say. If nobody has reasons for 2.59 compatibility to stick around, it would probably improve a lot. HTH! -- Diego

[libvirt] [PATCH] qemu: Use log output for pty assignment if 'info chardev' is unavailable
by Matthias Bolte 18 Jan '10

18 Jan '10

qemudFindCharDevicePTYsMonitor reports an error if 'info chardev' didn't provide information for a requested device, even if the log output parsing had found the pty path for that device. This makes pty assignment fail for older QEMU/KVM versions. For example KVM 72 on Debian doesn't support 'info chardev', so qemuMonitorTextGetPtyPaths cannot parse any useful information and the hash for device-id-to-pty-path mapping stays empty. Make qemudFindCharDevicePTYsMonitor report an error only if the log output parsing and the 'info chardev' parsing failed to provide the pty path. --- src/qemu/qemu_driver.c | 14 +++++++++++--- 1 files changed, 11 insertions(+), 3 deletions(-) diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index d13119f..783d9fc 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -1428,9 +1428,17 @@ qemudFindCharDevicePTYsMonitor(virConnectPtr conn, \ const char *path = (const char *) virHashLookup(paths, id); \ if (path == NULL) { \ - qemudReportError(conn, NULL, NULL, VIR_ERR_INTERNAL_ERROR,\ - _("no assigned pty for device %s"), id); \ - return -1; \ + if (chr->data.file.path == NULL) { \ + /* neither the log output nor 'info chardev' had a */ \ + /* pty path for this chardev, report an error */ \ + qemudReportError(conn, NULL, NULL, VIR_ERR_INTERNAL_ERROR, \ + _("no assigned pty for device %s"), id); \ + return -1; \ + } else { \ + /* 'info chardev' had no pty path for this chardev, */\ + /* but the log output had, so we're fine */ \ + continue; \ + } \ } \ \ VIR_FREE(chr->data.file.path); \ -- 1.6.3.3

[libvirt] LVM storage pool with existing mirrored volumes
by Ben Roberts 17 Jan '10

17 Jan '10

Hi, I tried to setup a lvm-backed storage pool, reusing an existing volume group which already contains a handful of mirrored logical volumes. For reference, I am using lvm 2.02.56-r3, qemu-kvm 0.12.1.2 and libvirt 0.7.5 on an up-to-date ~amd64 gentoo system. The first issue I encountered is when trying to activate the storage pool, the process fails with "internal error lvs command failed". This appears to be because the output of lvs is slightly different when using mirrored lvs, and is breaking the parser: /sbin/lvs --separator , --noheadings --units b --unbuffered --nosuffix --options lv_name,origin,uuid,devices,seg_size,vg_extent_size bigpool vms,,0PzrRS-8Ljs-SUq0-ywFH-BI3d-RI0V-aibupu,vms_mimage_0(0),vms_mimage_1(0),107374182400,4194304 backups,,Snk2NL-oJe3-GpTL-Qihs-ZjjG-xPyj-ufmwCp,backups_mimage_0(0),backups_mimage_1(0),214748364800,4194304 The device column of output would normally contain something like "/dev/sda(1234)", but here contains "vms_mimage_0(0),vms_mimage_1(0). This is causing the parser to misinterpret the output, and it believes the lv name to be suffixed with a trailing comma, eg "vms,". When trying to access "/dev/bigpool/vms,", the command errors with File or Directory not Found. When adding the --all parameter to lvs, the hidden mirroring lvs are visible, and these have the expected structure: vms,,0PzrRS-8Ljs-SUq0-ywFH-BI3d-RI0V-aibupu,vms_mimage_0(0),vms_mimage_1(0),107374182400,4194304 [vms_mlog],,vnOzg8-ynKc-kM8F-RKdM-xXC0-PJlG-qcgmFh,/dev/sda2(0),4194304,4194304 [vms_mimage_0],,2pXjHt-aARa-FOO7-ZL6N-ahpu-ebdr-P6Qxj3,/dev/sdb1(0),107374182400,4194304 [vms_mimage_1],,ITd8CT-JpKi-Y2a6-a4jc-2yDa-9VmG-gWgRd8,/dev/sdc1(51200),107374182400,4194304 Presumably, without the --all parameter and listing the internal mirroring volumes, libvirt will miscalculate sizes of LVs in the VG. This bug appears to prevent the use of any volume group which contains one or more mirrored logical volumes as a backend storage pool. -- Ben Roberts Computer Science MEng, Part IV Electronics and Computer Science, University of Southampton

>From the 'just a bit of fun' category, I've published a couple of videos visualizing the first four years of libvirt development The first, created using 'gource' [1]: http://www.youtube.com/watch?v=sEN4gxmCOuw The second, creating using 'code_swarm' [2]: http://www.youtube.com/watch?v=ptvATk1xPIw In both of these you can clearly tell when we started using GIT, since the improved patch author attribution results in an explosion of participants in the visualizations :-) Of course some of that is also due to the expanding libvirt development from the introduction of new drivers like VMWare and VirtualBox...

[libvirt] [PATCH] gnulib added a new syntax-check test: use $(VAR), not @VAR@
by Jim Meyering 15 Jan '10

15 Jan '10

Updating to newer gnulib also pulled in a new sytnax-check test that evoked new warnings. No big deal, but I addressed them. The only trick was to see that the warnings about @SCHEMADIR@ and @SYSCONFDIR@ were false positives. To allow them, I defined the variable in cfg.mk.

[libvirt] Using ESX domain XML for V2V
by Matthew Booth 15 Jan '10

15 Jan '10

I'm trying to use the ESX driver to extract metadata from ESX in an easily digestible form for driving V2V. I've noticed the domain XML seems to be missing a few bits: <features/> <graphics/> <input/> <serial/> and <console/> are also missing, but that could well be because they aren't present. Is this intentional? Should I be assuming some of the above because it's ESX, or is this an omission? Thanks, Matt -- Matthew Booth, RHCA, RHCSS Red Hat Engineering, Virtualisation Team M: +44 (0)7977 267231 GPG ID: D33C3490 GPG FPR: 3733 612D 2D05 5458 8A8A 1600 3441 EA19 D33C 3490

[libvirt] newer gnulib: requires several header-include fixes
by Jim Meyering 15 Jan '10

15 Jan '10

A week or two ago, upstream gnulib was fixed to be more namespace friendly in how it creates replacement headers. For some of its replacements (e.g., <stdio.h>, used via gnulib/lib/stdio.h), it would unnecessarily include another header, e.g., <stdlib.h>. That would make it so that an application using gnulib's <stdio.h> could think it's fine *not* to include stdlib.h, even though it uses a function like exit whose declaration usually requires an explicit inclusion of <stdlib.h>. [the example above is made up -- in reality it was more subtle] Well, now, those excess inclusions have been removed, and when I upgraded libvirt to use the latest gnulib, I saw many compilation failures due to missing #include directives. This series fixes the problems, then adds a change-set to update to the latest gnulib. Here are the one-line summaries: util.c: include required header, no longer masked by gnulib cpu_x86_data.h: include required header vbox: include required headers esx_vi_types.c: include required headers storage_backend.h: include required headers build: update gnulib submodule to latest >From ed2e5140a5a5529ca19e730d061f6d5b3872bb7f Mon Sep 17 00:00:00 2001 From: Jim Meyering <meyering(a)redhat.com> Date: Fri, 15 Jan 2010 10:31:23 +0100 Subject: [PATCH 1/6] util.c: include required header, no longer masked by gnulib Until recently, some gnulib-generated replacement headers included *other* headers that were not strictly necessary, thus masking the need in this file for an explicit <stdlib.h>. * src/util/util.c: Include <stdlib.h> for declarations of e.g., strtol, random_r, getenv, etc. --- src/util/util.c | 3 ++- 1 files changed, 2 insertions(+), 1 deletions(-) diff --git a/src/util/util.c b/src/util/util.c index 45ca657..67fae00 100644 --- a/src/util/util.c +++ b/src/util/util.c @@ -1,7 +1,7 @@ /* * utils.c: common, generic utility functions * - * Copyright (C) 2006, 2007, 2008, 2009 Red Hat, Inc. + * Copyright (C) 2006-2010 Red Hat, Inc. * Copyright (C) 2006 Daniel P.

[libvirt] [PATCH v2] Implement path lookup for USB by vendor:product
by Cole Robinson 14 Jan '10

14 Jan '10

Based off how QEMU does it, look through /sys/bus/usb/devices/* for matching vendor:product info, and if found, use info from the surrounding files to build the device's /dev/bus/usb path. This fixes USB device assignment by vendor:product when running qemu as non-root (well, it should, but for some reason I couldn't reproduce the failure people are seeing in [1], but it appears to work properly) [1] https://bugzilla.redhat.com/show_bug.cgi?id=542450 v2: Drop 'bus.addr only' checks in security drivers Use various util helpers Signed-off-by: Cole Robinson <crobinso(a)redhat.com> --- po/POTFILES.in | 1 + src/qemu/qemu_driver.c | 9 +-- src/security/security_selinux.c | 25 ++++----- src/security/virt-aa-helper.c | 32 +++++------ src/util/hostusb.c | 110 +++++++++++++++++++++++++++++++++++++- src/util/hostusb.h | 4 +- 6 files changed, 141 insertions(+), 40 deletions(-) diff --git a/po/POTFILES.in b/po/POTFILES.in index c9c78b6..3b82a74 100644 --- a/po/POTFILES.in +++ b/po/POTFILES.in @@ -55,6 +55,7 @@ src/uml/uml_conf.c src/uml/uml_driver.c src/util/bridge.c src/util/conf.c +src/util/hostusb.c src/util/json.c src/util/logging.c src/util/pci.c diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index deb8adc..f03ce91 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -2105,14 +2105,11 @@ static int qemuDomainSetHostdevUSBOwnership(virConnectPtr conn, struct qemuFileOwner owner = { uid, gid }; int ret = -1; - /* XXX what todo for USB devs assigned based on product/vendor ?

[libvirt] attach_device incompatibility between libvirt and qemu 0.12
by Gerhard Stenzel 14 Jan '10

14 Jan '10

Hi, I have a small libvirt-tck test script, in which I create a domain without a NIC, then use attach_device to add a NIC. And then I do a ping test to the domain.

[libvirt] [PATCH] Fix event-test segfault for mixed remote/local driver usage
by Matthias Bolte 14 Jan '10

14 Jan '10

If examples/domain-events/events-c/event-test.c uses a local driver for the hyperviror and a remote driver for storage then the segfault occurs in remoteDomainEventDispatchFunc because conn->privateData is used. The problem is as follows. The doRemoteOpen function registers remoteDomainEventFired as event handle and remoteDomainEventQueueFlush as event timeout. The doRemoteOpen function is used in remoteOpen and remoteOpenSecondaryDriver. So both handlers are registered for all types of remote drivers, but remoteDomainEventQueueFlush always uses conn->privateData. That's wrong when remoteDomainEventQueueFlush is called for any other driver than the hypervisor driver, it should use conn->storagePrivateData for the storage driver for example. In the common case this doesn't result in a segfault because in the common case all drivers for a connection are either all remote or all local and conn->privateData and conn->storagePrivateData are the same. But in the local Xen case ('event-test xen:///' executed in Domain-0, with a libvirtd running in Domain-0) the hypervisor driver is local and the storage driver is remote. This results in a mismatch between conn->privateData and conn->storagePrivateData. Now the call to remoteDomainEventQueueFlush in the context of the storage driver results in a segfault, because it assumes that conn->privateData points to remote driver private data, but it points to Xen driver private data. To fix this, the pointer to the private driver data gets passed as opaque parameter instead of the connection pointer. Because some functions called by the event handler functions need the connection pointer for other purposes than error reporting the connection pointer is passed as member of the private remote driver data struct. Now remoteDomainEventFired and remoteDomainEventQueueFlush have the correct private data pointer for the respective calling context. --- src/remote/remote_driver.c | 16 ++++++++-------- 1 files changed, 8 insertions(+), 8 deletions(-) diff --git a/src/remote/remote_driver.c b/src/remote/remote_driver.c index d6f5fce..582b85c 100644 --- a/src/remote/remote_driver.c +++ b/src/remote/remote_driver.c @@ -152,6 +152,7 @@ struct private_stream_data { struct private_data { virMutex lock; + virConnectPtr conn; int sock; /* Socket. */ int watch; /* File handle watch */ @@ -893,7 +894,7 @@ doRemoteOpen (virConnectPtr conn, if ((priv->watch = virEventAddHandle(priv->sock, VIR_EVENT_HANDLE_READABLE, remoteDomainEventFired, - conn, NULL)) < 0) { + priv, NULL)) < 0) { DEBUG0("virEventAddHandle failed: No addHandleImpl defined."

[libvirt] Set MAC address for host virtual interface?
by Neil Aggarwal 14 Jan '10

14 Jan '10

Hello: Is there a way to set the MAC address for the virtual interface on the host? I have this in my guests's XML file: <interface type='bridge'> <mac address='54:52:00:7d:f8:fc'/> <source bridge='br0'/> <target dev='tkl-joomla'/> </interface> the mac address line controls the guest interface but the host interface seems to get a random MAC address. This is causing a problem for me since I use Cacti to monitor the bandwidth usage of the guest machines. Every time I stop and start a guest, Cacti creates a new interface and I have to reset the graphs to use the new interfaces.

[libvirt] [BUG?] "no domain with matching uuid" error, when vm restarts
by su disheng 14 Jan '10

14 Jan '10

Hi, In the following libvirt API calling sequence, I always get an error "no domain with matching uuid" Connect _conn = new Connect("qemu:///system", false); _conn.domainDefineXML(kvm_guest_xml); Domain dm = _conn.domainLookupByName(kvm_guest_name); dm.create(); /* stop, undefine, and re-start the vm*/ dm.shutdown(); dm.undefine(); dm.domainDefineXML(kvm_guest_xml); /****A****/ Domain dm = _conn.domainLookupByName(kvm_guest_name); dm.create() /********Error!!!!**/ if I close the connection, and re-connect qemu at the end of /****A****/, then everything is OK. From the log, seems that uuid is not updated immediately, for this connection, the uuid is in the stale state? I am using libvirt 0.6.3, if it's a bug, does it fixed in the latest code? or Have I need to close the connection for each vm shutdown/re-define? I am a newbie in this API, any help are appreciated.

[libvirt] [PATCH] virterror: Don't invoke error callback for ERR_OK
by Cole Robinson 13 Jan '10

13 Jan '10

Since virDispatchError is now responsible for invoking the error callback, give it the same semantics as ReportError, which will skip VIR_ERR_OK (which is encountered when no error was raised). This fixes invoking the error callback after every non-erroring API call.

[libvirt] [PATCH 0/2] Some new utility functions
by Laine Stump 13 Jan '10

13 Jan '10

I'm planning to use these to fix the problems with creating storage volumes on root-squashing NFS servers, but since they may be of general utility I thought I'd throw them out for comments beforehand - it something different would make them more generally useful, better to change it now than after I've already finished code to use them. My plan is to use virRunWithHook() to call setuid (or possibly some sort of capng calisthenics) prior to execing qemu-img and qcow-create. virFileCreate and virDirCreate will be used when creating raw volumes. I have written test code to verify that virFileCreate works in several different scenarios. Haven't done so with virRun yet, but it's a fairly simple change, just exposing __virExec arguments that were already there. (I'd previously written test code (yes, it worked ;-)) that used a virRun with uid/gid args added on, but have decided against that approach, since this seems more flexible)

[libvirt] [PATCH] node_device: udev: Use base 16 for product/vendor
by Cole Robinson 13 Jan '10

udev doesn't prefix USB product/vendor info with '0x', so the strtol conversions were wrong for the product field (vendor already set the correct base).

[libvirt] VMware vCenter support
by Fulop, Balazs 13 Jan '10

13 Jan '10

Dear List, I find the ESX driver in libvirt quite useful to perform powercycle operations on a VM. However, I need to connect to an ESX server even when the VM is managed on the VMware 4.0 platform. Reading this mail: http://www.mail-archive.com/libvir-list@redhat.com/msg18259.html makes me think that support to connect directly to a vCenter using the scheme vpx:// is not far from becoming a reality. Could you please provide an estimated timeline for this and notes on possible further enhancements in the ESX driver code? Thank you very much in advance.

[libvirt] [PATCH] Implement path lookup for USB by vendor:product
by Cole Robinson 13 Jan '10

13 Jan '10

Based off how QEMU does it, look through /sys/bus/usb/devices/* for matching vendor:product info, and if found, use info from the surrounding files to build the device's /dev/bus/usb path.

[libvirt] [PATCH] Fix migration in xend driver
by Jim Fehlig 12 Jan '10

12 Jan '10

Upstream xen has changed parameters to the migration operation several times over the past 18 months. Changeset 17553 removed the resouce parameter, Changesets 17709, 17753, and 20326 added ssl, node, and change_home_server parameters respectively. Fortunately, testing has revealed that xend will fail the operation if a parameter is missing but happily honor it if unknown parameters are provided. Thus all currently supported parameters can be provided, satisfying current xend but not regressing older versions. --- src/xen/xend_internal.c | 14 ++++++++++---- 1 files changed, 10 insertions(+), 4 deletions(-) diff --git a/src/xen/xend_internal.c b/src/xen/xend_internal.c index be033f5..d9bfa15 100644 --- a/src/xen/xend_internal.c +++ b/src/xen/xend_internal.c @@ -4553,15 +4553,21 @@ xenDaemonDomainMigratePerform (virDomainPtr domain, DEBUG("hostname = %s, port = %s", hostname, port); - /* Make the call. */ + /* Make the call. + * NB: xend will fail the operation if any parameters are + * missing but happily accept unknown parameters.

[libvirt] Start external programm on network-setup
by Dominik Bruhn 12 Jan '10

12 Jan '10

Hy, im using libvirt-bin on debian and configured the network of libvirt to be a standalone bridge. Is there a possibility to run a program after the bridge has successfully and completly set up by libvirtd? I would like to restart shorewall (a firewall) when the bridge is set up to activate MASQ and DNAT and other policies which I need. I would also like to start my own configured dnsmasq when the interface is up (can't start it realier because it has to bind to the interface). I hope thats the right place to ask such a question, if not, please direct me. Thanks for the help -- Dominik mailto: dominik(a)dbruhn.de

[libvirt] [PATCH 0/5] Fix various error squashing issues
by Cole Robinson 12 Jan '10

12 Jan '10

The following series adds internal APIs that help prevent legitimate errors from being overwritten by other errors (for example in cleanup routines). The majority of this series is a patch from Dan[1] which makes error callbacks explictly triggered when exiting an API call, rather than when an error is raised (I've updated this to cover the current codebase) [1] http://gitorious.org/~berrange/libvirt/staging/commits/error-callbacks Cole Robinson (4): virterror: Add virSetError qemu: migrate: Save MigratePerform error in MigrateFinish. libvirt.c: Preserve MigratePerform failure qemu: Disable errors in qemudShutdownVMDaemon Daniel P.

I'm curious to know why when using the UIR xen:/// multiple myEventAddHandleFunc() calls occurred. Are there and fields I could use to identify and ignore the spurious calls? I'd like to use the event monitoring for several remote Xen hosts. I assume I'll have to modify the code to connect remotely to each host and hope for just one myEventAddHandleFunc() call per host. Thanks for your assistance it's much apprecied, Regards, Pete

[libvirt] [PATCH] remote_driver.c: fix a NULL dereference in remoteDomainEventQueueFlush().
by kakuma 12 Jan '10

12 Jan '10

Hi, all. There is a case of a NULL dereference in function remoteDomainEventQueueFlush() in remote_driver.c In the case of local connection conn->privateData->domainEvents isn't reserved. In this case it will occurs segment fault. (for example examples/domain-events/events-c/event-test.c) I think the following patch will be available. Thanks. --- src/remote/remote_driver.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/src/remote/remote_driver.c b/src/remote/remote_driver.c index d6f5fce..b112fd3 100644 --- a/src/remote/remote_driver.c +++ b/src/remote/remote_driver.c @@ -8709,7 +8709,7 @@ void remoteDomainEventQueueFlush(int timer ATTRIBUTE_UNUSED, void *opaque) { virConnectPtr conn = opaque; - struct private_data *priv = conn->privateData; + struct private_data *priv = conn->networkPrivateData; virDomainEventQueue tempQueue; remoteDriverLock(priv); -- 1.5.6.1 -- kakuma <f-kak(a)ksh.biglobe.ne.jp>

qemudWaitForMonitor calls qemudReadLogOutput with qemudFindCharDevicePTYs as callback. qemudFindCharDevicePTYs calls qemudExtractTTYPath to assign a string to chr->data.file.path. Afterwards qemudWaitForMonitor may call qemudFindCharDevicePTYsMonitor that overwrites chr->data.file.path without freeing the old value. This results in leaking the memory allocated by qemudExtractTTYPath.

To make sure I understand the API. If I have a domain defined, but not started.. it will show up in the list returned by: virConnectListDefinedDomains but not in the list virConnectListDomains Conversely, if it is started... it will only be in the list: virConnectListDomains not in the list virConnectListDefinedDomains Is that correct? -- bk

[libvirt] LXC: init problem
by Robin Green 11 Jan '10

11 Jan '10

I'm trying to install Exherbo Linux in an LXC container using libvirt. I've basically succeeded, in that I can "virsh console" in and start sshd, but I haven't managed to boot it starting from /sbin/init rather than /bin/bash. If I have the following (I probably should have modified the uuid and the mac address from the standard example, but that's not relevant): <domain type='lxc'> <name>exherbo</name> <uuid>a4047015-171c-ae56-bc1e-57102d4b86bf</uuid> <memory>1000000</memory> <currentMemory>1000000</currentMemory> <vcpu>2</vcpu> <os> <type arch='i686'>exe</type> <init>/sbin/init</init> </os> <clock offset='utc'/> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>destroy</on_crash> <devices> <emulator>/usr/libexec/libvirt_lxc</emulator> <filesystem type='mount'> <source dir='/home/greenrd/exherbo'/> <target dir='/'/> </filesystem> <interface type='network'> <mac address='52:54:00:56:64:42'/> <source network='default'/> <target dev='veth0'/> </interface> <console type='pty'> <target port='0'/> </console> </devices> </domain> and do virsh --connect lxc:/// start exherbo && virsh --connect lxc:/// console exherbo nothing appears - then if I press Enter, the container dies. In pstree all I see that's relevant is: ├─libvirt_lxc───libvirt_lxc so it looks like init dies. If I run init in gdb in the container I just get: Starting program: /sbin/init Usage: init 0123456SsQqAaBbCcUu Program exited with code 01. so I suppose it could be wanting a runlevel as argument. I'm guessing though that /sbin/init is running in a different mode - telinit mode - as its PID is not 1. Is there any way to get an instant console from the virsh start command, so I can see what's going on? -- Robin

Ah, are you using the version of libvirt that comes with RHEL 5.4? That version has been patched to only look for the qemu-kvm binary in one spot: /usr/libexec/qemu-kvm IIRC. You could try to work with that, but since you are already building upstream KVM, virt-manager, and virtinst, might not be a bad idea to pull upstream libvirt as well. >>> Once i tried to compile the virt-manager-0.8.0, but when i make check, >>> it returns: >>> >>> PYTHONPATH=./..:../graphWidgets/.libs python addhardware.py && touch >>> .tstamp.addhardware.py >>> Traceback (mos! t recent call last): >>> File "addhardware.py", line 32, in ? >>> from virtinst import VirtualCharDevice, VirtualDevice, >>> VirtualVideoDevice >>> >>> when i rpm -ivh virt-manager-0.6.1-8.el5.ia64.rpm, it could work. >>> >>> I don't know why this error occur.

'make check' doesn't work in the virt-manager code base, never taken the time to fix it. You should just be able to 'make && make install', or 'make' and python src/virt-manager.py to run from the source dir. If running virt-manager then throws an error, report here and Ill try to help. - Cole

[libvirt] [PATCH] avoid another "make distcheck" failure
by Jim Meyering 09 Jan '10

"make uninstall" would fail rm: cannot remove `/home/j/w/co/libvirt/libvirt-0.7.5/_inst/share/gtk-doc/html\ /libvirtdevhelp/libvirt.devhelp': No such file or directory rm: cannot remove `/home/j/w/co/libvirt/libvirt-0.7.5/_inst/share/gtk-doc/html\ /libvirtdevhelp/index.html': No such file or directory There are two problems: first, "libvirtdevhelp" is not a valid dir name.

[libvirt] Some questions about the libvirt ESX driver
by Richard W.M. Jones 08 Jan '10

08 Jan '10

I'm playing with VMWare ESX 4.0 and I decided to try driving it from libvirt [git version]. Here are some random questions and issues I encountered, in no particular order. Listing domains works fine, but: (a) I have to specify ?no_verify=1 to get it to ignore the lack of valid https certificate. Is there some documentation on how to set up certificates correctly? [vSphere gives exactly the same error] (b) I have to type the root password (of the ESX server) each time. Can I avoid that? $ sudo ./tools/virsh -c 'esx://192.168.2.121/?no_verify=1' list --all Enter username for 192.168.2.121 [root]: Enter root password for 192.168.2.121: Id Name State ---------------------------------- - TestLinux shut off - TestWin shut off (c) Starting domains doesn't seem to work, and the error message is obscure: $ sudo ./tools/virsh -c 'esx://192.168.2.121/?no_verify=1' start TestLinux Enter username for 192.168.2.121 [root]: Enter root password for 192.168.2.121: error: Failed to start domain TestLinux error: internal error HTTP response code 500 for call to 'PowerOnVM_Task'. Fault: ServerFaultCode - The operation is not allowed in the current state. Is this to do with the "ask questions" API that was discussed on this list before? Specifying auto_answer=0 or auto_answer=1 didn't make any difference. (d) dumpxml XML output looks very good, and consistent with the other drivers. However it produces an odd <source file> attribute: <disk type='file' device='disk'> <driver name='lsilogic'/> <source file='[Storage1] TestLinux/TestLinux.vmdk'/> <target dev='sda' bus='scsi'/> </disk> <disk type='file' device='cdrom'> <source file='[Storage1] Fedora-12-x86_64-Live.iso'/> <target dev='hdc' bus='ide'/> </disk> (e) pool-list, net-list are not supported by the driver. That's a particular problem for me because I was really hoping to use the storage APIs from libvirt to access the VMDK files that contain domains (eg. [Storage1] TestLinux/TestLinux.vmdk in the example above). Is support for storage (particularly) and/or networks on the horizon for this driver?

[libvirt] RFC: Create a separate libvirt users mailing list ?
by Daniel P. Berrange 08 Jan '10

08 Jan '10

Hi Folks, We've been brainstorming ways to improve/broaden the libvirt community and one (of many) ideas is to create a separate libvirt users mailing list. The rationale is that this list is 95% patch submission from developers, often very high traffic and thus it may not be appealing for ordinary users to subscribe just to ask a question about libvirt usage. Although there is the virt-tools mailing list, that is really focused on the virt-manager family of apps, not a general purpose libvirt users community. Thus we're considering creating a new list libvirt-users(a)redhat.com To serve as a home for discussions relating to - Administrators/users of libvirt / libvirtd / virsh - Developers building applications on top of libvirt - Anyone else wishing to ask/talk about libvirt architecture / concepts / etc in real world deployment While the current list libvir-list(a)redhat.com To serve as continued home for most current traffic, specifically - Development of libvirt itself (libvirtd, hypervisor drivers, etc) - Development of libvirt language bindings (perl, python, java, etc) - Patch submission for libvirt & language bindings Essentially all libvirt code patches would be on libvir-list, while libvirt-users would be for app developer / end user admin discussions. For this to work of course, a significant number developers of libvirt currently on this list would also have to join libvirt-users, so we have people on the new list who are able to answer questions :-) Before we create a new list we'd like to hear from people on this list as to wether they think this would be beneficial. In particular we'd like your opinion if you are someone who's likely to switch to be exclusively on the libvirt-users list.

When you use virt-manager it has libvirtd fork/exec qemu-kvm. libvirtd will drop privileges and run qemu-kvm as user qemu (or perhaps root if you've edited qemu.conf). Regardless of the user, it clears capabilities. Reading PCI config space beyond just the header requires CAP_SYS_ADMIN. The above is reading the first 4 bytes of device dependent config space, and the kernel is returning 0 because qemu doesn't have CAP_SYS_ADMIN. Basically, this means that device assignment w/ libvirt will break MSI/MSI-X because qemu will never be able to see that the host device has those PCI capabilities. This, in turn, renders VF device assignment useless (since a VF is required to support MSI and/or MSI-X). Granting CAP_SYS_ADMIN for each qemu instance that does device assignment would render the privilege reduction useless (CAP_SYS_ADMIN is the kitchen sink catchall of the Linux capability system). Hmmph...

[libvirt] [PATCH] Qemu: ask for memory preallocation with large pages
by Daniel Veillard 08 Jan '10

[libvirt] DNAT, bridge, iptables and network
by Mihamina Rakotomandimby 08 Jan '10

08 Jan '10

Manao ahoana, Hello, Bonjour, My server has 3 public IPs: IP1, IP2, IP3. I intend to create 3 bridges: virbr1, virbr2, virbr3. Each bridge will NAT from 3 to 5 KVM guests. About IP1: I would like incoming connexion on IP1 to: - IP1:80 to be DNAT'd to one virbr1 VM, specialized on HTTP - IP1:3306 to be DNAT'd to another virbr1 VM, specialized on MySQL - IP1:53 to be DNAT'd to another virbr1 VM, specialized on DNS Same about IP2 and IP3. Should I assign a public IP address to each brdige? I think "no" because there will be a problem of network segment: --> What range will I give to the guests? I think my only solution is to give private IPs (192.168.X.X) to the brigdes (3 separate subnets), and use iptables with something like: iptables -t nat -A PREROUTING -p tcp -m tcp -d $IP1 --dport 80 \ -j DNAT --to-destination $VIRBR1_HTTP_GUEST iptables -t nat -A PREROUTING -p tcp -m tcp -d $IP1 --dport 3306 \ -j DNAT --to-destination $VIRBR1_MySQL_GUEST iptables -t nat -A PREROUTING -p udp -d $IP1 --dport 53 \ -j DNAT --to-destination $VIRBR1_DNS_GUEST Should be alright?

[libvirt] [Patch v0.5] iSCSI Multi-IQN (Libvirt Support)
by Shyam Iyer 08 Jan '10

08 Jan '10

This patch set realizes the multi-IQN concept discussed in an earlier thread http://www.mail-archive.com/libvir-list@redhat.com/msg16706.html And here .. http://www.mail-archive.com/libvir-list@redhat.com/msg17499.html The patch realizes an XML schema like the one below and allows libvirt to read through it to create storage pools. These XMLs when created using a virtualization manager realize unique VM to storage LUN mappings through a single console and thus opening up possibilities for the following scenarios - * possibility of multiple IQNs for a single Guest * option for hypervisor's initiator to use these IQNs on behalf of the guest Change Log from v0.4: 1) Set default tab space to 4(Hopefully this is corrected this time ;) ) 2) Review comments from Dave Allan a) Use output of "iscsiadm -m iface" to search for existing iqn names in the iface files. 3) Create new unique iface file names for user provided iqn names if the iqns are not present in the existing iface files. Change Log from v0.3: 1) Set default tab space to 4 2) Use Case Description for Commit Log 3) Review comments from Dave Allan a) No initiator iqn in the xml would mean use of the default initiator iqn name b) Initiator iqn provided would mean a unique session to be created using the provided iqn name. c) Single iSCSI session per pool 4) Added syntax in doc/schemas/storagepool.rng There are no new errors introduced by this patch with "make check" and "make syntax-check" tests.

[libvirt] [PATCH] [RFC] xen domctl version 6
by Jim Fehlig 07 Jan '10

07 Jan '10

xen-unstable c/s 20685 changed the domctl interface, adding a field to xen_domctl_getdomaininfo structure. This additional field causes stack corruption in libvirt. xen-unstable c/s 20711 rightly bumped the domctl interface version so it is at least possible to handle the new field. The attached patch accounts for shr_pages field added to xen_domctl_getdomaininfo structure. I'm not thrilled about the changes to all the macros - suggestions for improvement welcomed. Tested with domctl version 5 and 6. Regards, Jim

The update from qemu 0.11.0 to qemu 0.12.1 in the virt-preview repository seems to have broken things.

[libvirt] [PATCH] xend_internal: don't let invalid input provoke NULL dereference
by Jim Meyering 06 Jan '10

06 Jan '10

If there's a good reason to test for NULL "conn", then we certainly must not dereference "conn" before that point. This assumes we do want to retain the NULL test. Note that many other functions perform this same test. >From 2c7b628728efcb5a59c1e7aa1cba763f5ef0045a Mon Sep 17 00:00:00 2001 From: Jim Meyering <meyering(a)redhat.com> Date: Wed, 6 Jan 2010 12:59:21 +0100 Subject: [PATCH] xend_internal: don't let invalid input provoke NULL dereference * src/xen/xend_internal.c (xenDaemonOpen_unix): Do not dereference a NULL "conn".

[libvirt] [PATCH] esx: Fix 'vpx' MAC address range and allow arbitrary MAC addresses
by Matthias Bolte 06 Jan '10

06 Jan '10

The MAC addresses with 00:50:56 prefix are split into several ranges: 00:50:56:00:00:00 - 00:50:56:3f:ff:ff 'static' range (manually assigned) 00:50:56:80:00:00 - 00:50:56:bf:ff:ff 'vpx' range (assigned by a VI Client) Erroneously the 'vpx' range was assumed to be larger and to occupy the remaining addresses of the 00:50:56 prefix that are not part of the 'static' range. 00:50:56 was used as prefix for generated MAC addresses, this is not possible anymore, because there are gaps in the allowed ranges. Therefore, change the prefix to 00:0c:29 which is the prefix for auto generated MAC addresses anyway. Allow arbitrary MAC addresses to be used and set the checkMACAddress VMX option to false in case the MAC address doesn't fall into any predefined range. * docs/drvesx.html.in: update website accordingly * src/esx/esx_driver.c: set the auto generation prefix to 00:0c:29 * src/esx/esx_vmx.c: fix MAC address range handling and allow arbitrary MAC addresses * tests/vmx2xml*, tests/xml2vmx*: add some basic MAC address range tests --- docs/drvesx.html.in | 74 ++++++++++++++++++++-- src/esx/esx_driver.c | 2 +- src/esx/esx_vmx.c | 49 +++++++++------ tests/vmx2xmldata/vmx2xml-ethernet-generated.vmx | 8 +++ tests/vmx2xmldata/vmx2xml-ethernet-generated.xml | 19 ++++++ tests/vmx2xmldata/vmx2xml-ethernet-other.vmx | 8 +++ tests/vmx2xmldata/vmx2xml-ethernet-other.xml | 19 ++++++ tests/vmx2xmldata/vmx2xml-ethernet-static.vmx | 7 ++ tests/vmx2xmldata/vmx2xml-ethernet-static.xml | 19 ++++++ tests/vmx2xmldata/vmx2xml-ethernet-vpx.vmx | 7 ++ tests/vmx2xmldata/vmx2xml-ethernet-vpx.xml | 19 ++++++ tests/vmx2xmltest.c | 5 ++ tests/xml2vmxdata/xml2vmx-ethernet-generated.vmx | 13 ++++ tests/xml2vmxdata/xml2vmx-ethernet-generated.xml | 14 ++++ tests/xml2vmxdata/xml2vmx-ethernet-other.vmx | 13 ++++ tests/xml2vmxdata/xml2vmx-ethernet-other.xml | 14 ++++ tests/xml2vmxdata/xml2vmx-ethernet-static.vmx | 12 ++++ tests/xml2vmxdata/xml2vmx-ethernet-static.xml | 14 ++++ tests/xml2vmxdata/xml2vmx-ethernet-vpx.vmx | 12 ++++ tests/xml2vmxdata/xml2vmx-ethernet-vpx.xml | 14 ++++ tests/xml2vmxtest.c | 5 ++ 21 files changed, 320 insertions(+), 27 deletions(-) create mode 100644 tests/vmx2xmldata/vmx2xml-ethernet-generated.vmx create mode 100644 tests/vmx2xmldata/vmx2xml-ethernet-generated.xml create mode 100644 tests/vmx2xmldata/vmx2xml-ethernet-other.vmx create mode 100644 tests/vmx2xmldata/vmx2xml-ethernet-other.xml create mode 100644 tests/vmx2xmldata/vmx2xml-ethernet-static.vmx create mode 100644 tests/vmx2xmldata/vmx2xml-ethernet-static.xml create mode 100644 tests/vmx2xmldata/vmx2xml-ethernet-vpx.vmx create mode 100644 tests/vmx2xmldata/vmx2xml-ethernet-vpx.xml create mode 100644 tests/xml2vmxdata/xml2vmx-ethernet-generated.vmx create mode 100644 tests/xml2vmxdata/xml2vmx-ethernet-generated.xml create mode 100644 tests/xml2vmxdata/xml2vmx-ethernet-other.vmx create mode 100644 tests/xml2vmxdata/xml2vmx-ethernet-other.xml create mode 100644 tests/xml2vmxdata/xml2vmx-ethernet-static.vmx create mode 100644 tests/xml2vmxdata/xml2vmx-ethernet-static.xml create mode 100644 tests/xml2vmxdata/xml2vmx-ethernet-vpx.vmx create mode 100644 tests/xml2vmxdata/xml2vmx-ethernet-vpx.xml diff --git a/docs/drvesx.html.in b/docs/drvesx.html.in index b7909ff..44a144f 100644 --- a/docs/drvesx.html.in +++ b/docs/drvesx.html.in @@ -16,8 +16,8 @@ SOAP based <a href="http://www.vmware.com/support/developer/vc-sdk/visdk25pubs/ReferenceGuide/"> VMware Virtual Infrastructure API</a> (VI API) to communicate with the - ESX server, like the VMware Virtual Infrastructure Client does.

[libvirt] [PATCH] qemu_driver.c: remove useless, warning-provoking test
by Jim Meyering 05 Jan '10

05 Jan '10

Tools like coverity and maybe clang notice that we dereference uri_out, and then (later) test whether uri_out is NULL. Obviously one or the other must go. Presuming that we will always pass a non-NULL uri_out arg to this function, I chose to mark that parameter as ATTRIBUTE_NONNULL. I removed the unnecessary test, too. If anyone is concerned that a non-NULL (non-literal) value will be passed, I can also add an assertion. >From 6ce3a9656d978b37d866f55606bc5031ad8e6b2f Mon Sep 17 00:00:00 2001 From: Jim Meyering <meyering(a)redhat.com> Date: Tue, 5 Jan 2010 16:32:11 +0100 Subject: [PATCH] qemu_driver.c: remove useless, warning-provoking test * src/qemu/qemu_driver.c (qemudDomainMigratePrepare2): Remove useless test of always-non-NULL uri_out parameter.
