[libvirt] [PATCH v4] Implement DNS SRV record into the bridge driver
by Michal Novotny 05 Dec '11

05 Dec '11

Hi, this is the fourth version of my SRV record for DNSMasq patch rebased for the current codebase to the bridge driver and libvirt XML file to include support for the SRV records in the DNS. The syntax is based on DNSMasq man page and tests for both xml2xml and xml2argv were added as well. This is basically un-reviewed version 3 of this patch rebased to the current codebase with changed version information to 0.9.9 as it's supposed to go in 0.9.9 or later because of current 0.9.8 features freeze. Also, the second part of this patch is fixing the networkxml2argv test to pass both checks, i.e. both unit tests and also syntax check.

[libvirt] [PATCH 00/14] Add a virtlockd lock manager daemon
by Daniel P. Berrange 05 Dec '11

05 Dec '11

The lock manager infrastructure we recently added to QEMU only has two possible drivers at this time, 'nop' and 'sanlock'. The former does absolutely nothing, while the latter requires a 3rd party package installed and is a little heavy on disk I/O and storage requirements. This series adds a new daemon 'virtlockd' which is intended to be enabled by default on all hosts running 'libvirtd'. This daemon provides a service for disk locking based on the traditional fcntl() lock primitives. There is a new libvirt manager plugin which talks to this daemon over RPC. The reason for doing the locks in a separate process is that we want the locks to remain active, even if libvirtd crashes, or is restarted. The virtlockd daemon has this one single job so should be pretty reliable and selfcontained. This patch series really benefits from the new RPC APIs, requiring minimal code for the new daemon / client At this time, virtlockd does not lock the actual disk files, but instead creates a lockspace & leases under /var/lib/libvirt/lockd. The lockspace we use for disks is named org.libvirt.lockd.files, and lease names are based on a SHA256 checksum of the fully qualified disk name. eg /var/lib/libvirt/lockd/org.libvirt.lockd.files/adf94fc33a24da1abff7dd7374a9919bb51efee646da8c3ac464c10cd59750bd These leases are all zero-bytes long and no I/O is ever performed on them, only fcntl() is used. So there is material overhead. Whenever creating or deleting leases, we first acquire a lock on /var/lib/libvirt/lockd/org.libvirt.lockd.files/org.libvirt.lockd.index A non-root virtlockd will instead use $HOME/.libvirt/lockd By default we gain protection out of the box against - Starting two guests on the same host with the same disk image not marked with <shareable/> - libvirtd getting confused and forgetting a guest, allowing it to be started for a 2nd time If the admin mounts a shared filesytem (eg NFS) on /var/lib/libvirt/lockd then this protection is extended across all hosts sharing that mount volume. As part of this series, I also introduce support for systemd services for libvirtd and libvir-guests.

[libvirt] Add <console> support
by Christophe Fergeau 05 Dec '11

05 Dec '11

Hi, This patch series adds support for setting <console> nodes as has been discussed in the "[PATCH libvirt-glib 02/15] Add objects for dealing with <console> devices" thread. It introduces a GVirConfigDomainChardev which derives from GVirConfigDomainDevice. The actual classes to create <console>, <serial>, <parallel> nodes will inherit from this parent class. Then we have GVirConfigDomainChardevSource which derives from GVirConfigObject (with a dummy root node name) and from which derives GVirConfigDomainChardevSourcePty. A GVirConfigDomainChardevSourcePty is associated to a GVirConfigDomainConsole object through GVirConfigDomainChardev::add_source. Maybe it should be ::set_source, I'm unsure... The code from ::add_source directly messes with the xml nodes so a careful review won't hurt :) At this point I consider this to be at least 50% RFC so we can still redesign the whole thing.

[libvirt] [PATCH 00/10] Console coruption with two or more clients series
by Peter Krempa 05 Dec '11

05 Dec '11

This series fixes anoying console corruption if two clients try to connect at same time to the console. The current state of this is, that two/more of libvirt iohelpers are spawned on the same time that compete for data from the pty. This causes that each of the consoles get scrambled and unusable. Patches fdstream: Emit stream abort callback even if poll() doesnt. virnetclientstream: Propagate stream error messages to callback daemon: Subscribe the stream event callback for error events. add the ability to abort a stream from the daemon side. fdstream: Add internal function to check if a fdstream is open This patch adds a helper function that checks internally if a fdstream is open and working. virsh: fix console stream error reporting Add flags for virDomainOpenConsole virsh: add support for VIR_DOMAIN_CONSOLE_FORCE flag This patches add instrumentation to virsh that supports the new ability to abort streams from the daemon side and adapts the console callback to handle this. These patches also add a new flag set for virDomainOpenConsole API call that allow users to control the if the existing console connection should be left in place or killed in favor of the new one qemu: Add ability to abort existing console while creating new one lxc: Add ability to abort existing console when creating a new one uml: Add ability to abort existing console when creating a new one These patches modify the hypervisor drivers so that they are aware of existing console connections and refuse to create a new one (or kill the old). The xen driver also supports console in a similar way like the previously mentioned drivers, but lacks the means to store a stream reference permanently. I'll look in if it's possible to modify this driver to support this new functionality.

by Juan Quintela 05 Dec '11

05 Dec '11

Hi Please send in any agenda items you are interested in covering. Proposal (from Anthony): > 1. A short introduction to each of the guest agents, what guests they > support, and what verbs they support. > 2. A short description of key requirements from each party (oVirt, > libvirt, QEMU) for a guest agent > 3. An open discussion about possible ways to collaborate/converge. Notice that guest integration will take more than one week (Anthony estimation also). For libvirt and ovirt folks, please contact me or Chris for details of the call. Thanks, Juan.

[libvirt] [PATCH] qemu: Rework handling of shutdown event
by Jiri Denemark 05 Dec '11

05 Dec '11

When QEMU guest finishes its shutdown sequence, qemu stops virtual CPUs and when started with -no-shutdown waits for us to kill it using SGITERM. Since QEMU is flushing its internal buffers, some time may pass before QEMU actually dies. We mistakenly used "paused" state (and events) for this which is quite confusing since users may see a domain going to pause while they expect it to shutdown. Since we already have "shutdown" state with "the domain is being shut down" semantics, we should use it for this state. However, the state didn't have a corresponding event so I created one and called its detail as VIR_DOMAIN_EVENT_SHUTDOWN_FINISHED (guest OS finished its shutdown sequence) with the intent to add VIR_DOMAIN_EVENT_SHUTDOWN_STARTED in the future if we have a sufficiently capable guest agent that can notify us when guest OS starts to shutdown. --- include/libvirt/libvirt.h.in | 10 +++ src/qemu/qemu_process.c | 126 ++++++++++++++++++++++++++++++------------ 2 files changed, 100 insertions(+), 36 deletions(-) diff --git a/include/libvirt/libvirt.h.in b/include/libvirt/libvirt.h.in index d01d1bc..8d4a049 100644 --- a/include/libvirt/libvirt.h.in +++ b/include/libvirt/libvirt.h.in @@ -2288,6 +2288,7 @@ typedef enum { VIR_DOMAIN_EVENT_SUSPENDED = 3, VIR_DOMAIN_EVENT_RESUMED = 4, VIR_DOMAIN_EVENT_STOPPED = 5, + VIR_DOMAIN_EVENT_SHUTDOWN = 6, } virDomainEventType;

[libvirt] [PATCH] Introduce gvir_set_error (and friends) & convert all code
by Daniel P. Berrange 05 Dec '11

05 Dec '11

From: "Daniel P. Berrange" <berrange(a)redhat.com> The pattern GError **error; .... *err = gvir_error_new(...) is dangerous because 'err' could be NULL, and it is tedious to expect everyone to check.

[libvirt] [PATCH 0/2] Expose virNodeGetCPUStats and virNodeGetMemoryStats in python
by Peter Krempa 05 Dec '11

05 Dec '11

These patches add two API functions to the libvirt python bindings, that were missing. The constants denoting a summary stat value instead of a separate per-node values was declared using a preprocessor macro: ... #define VIR_NODE_MEMORY_STATS_ALL_CELLS (-1) #define VIR_NODE_CPU_STATS_ALL_CPUS (-1) ... This inhibits automatic generation of these constants in the automaticaly generated python library code. If this change is too controversial, there's another option: Including these constants in the python library (using libvirt-override.py). Please let me know which of those options you prefer. Thanks Peter Peter Krempa (2): python: Expose binding for virNodeGetCPUStats() python: Expose binding for virNodeGetMemoryStats() include/libvirt/libvirt.h.in | 12 +++-- - change macro definitions to enums python/libvirt-override-api.xml | 14 ++++++ - add doc's about newly added functions python/libvirt-override.c | 95 +++++++++++++++++++++++++++++++++++++++ - add code for calling those functions and reclaiming return values. 3 files changed, 117 insertions(+), 4 deletions(-) -- 1.7.3.4

Hi, I am using the python api: domain.abortjob(), if there is no job I get exception with error code: VIR_ERR_OPERATION_INVALID with the error message: 'Requested operation is not valid: no job is active on the domain' when there is a job I get the same exception code with the same error message, in addition I get another exception: libvirtError ('virDomainMigrateToURI2() failed', dom=self) libvirtError: operation failed: migration job: canceled by client the migration thread is throwing as well: libvirtError ('virDomainMigrateToURI2() failed', dom=self) libvirtError: operation failed: migration job: canceled by client Should the same error should be for this two cases?

[libvirt] implementing locking with libvirt on ubuntu
by Upendra Moturi 05 Dec '11

05 Dec '11

Hi I am trying to implement locking i,e two vms are not started with same disk on ubuntu. Using libvirt 0.9.7 (Installed it from source) qemu-kvm 0.14.1 kernel 3.0.0-13-server Steps followed while installing from source cd libvirt-0.9.7 ./configure make make install I found that sanlock or virtlockd (fcntl) daemons can do that,but not able implement it. I dont find virtlockd daemon running. >From below link http://www.redhat.com/archives/libvir-list/2011-July/msg00337.html it is said to create lockd directory under /var/lib/libvirt I dont find this directory after installation from source Am i missing something ? Please guide me in implementing locking on ubuntu. -- Thanks and Regards, Upendra.M

[libvirt] [PATCH] build: fix build at -O2 on rawhide
by Eric Blake 02 Dec '11

02 Dec '11

I had previously tested commit 059d746 with -O intentionally omitted from my CFLAGS; but that means that I missed out on this warning from gcc 4.6.2 when optimizations are enabled: util/buf.c: In function 'virBufferGetIndent': util/buf.c:86:1: error: function might be candidate for attribute 'pure' [-Werror=suggest-attribute=pure] While it is probably a good idea to add the attributes and silence this warning, it's also invasive; 'make -k' found more than 75 such complaints. And it doesn't help that gcc 4.6.2 is still buggy (coreutils reported a case where gcc 4.6.2 incorrectly suggested marking a function pure that incremented a global variable; fixed in gcc 4.7). So the best fix for now is to disable the warning. It also doesn't help that I stumbled across another problem - gcc documents that -Wsuggest-attribute=pure only warns if you use -O, or if you use -fipa-pure-const. But in practice, when I omitted -O but added -fipa-pure-const, the warnings are fickle - I got warnings for simple compilation that disappeared when I also added -fPIC. And the way libtool compiles things is with -fPIC first, then without -fPIC but with errors sent to /dev/null - which meant that without disabling -Wsuggest-attribute=pure, I got a compile error with no message. :( See http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10197 * m4/virt-compile-warnings.m4 (LIBVIRT_COMPILE_WARNINGS): Silence -Wsuggest-attribute warnings for now. --- Pushing under the build-breaker rule. m4/virt-compile-warnings.m4 | 8 ++++++++ 1 files changed, 8 insertions(+), 0 deletions(-) diff --git a/m4/virt-compile-warnings.m4 b/m4/virt-compile-warnings.m4 index 213b3db..34a89c9 100644 --- a/m4/virt-compile-warnings.m4 +++ b/m4/virt-compile-warnings.m4 @@ -116,2 +116,2 @@ AC_DEFUN([LIBVIRT_COMPILE_WARNINGS],[ gl_WARN_ADD([-fdiagnostics-show-option]) gl_WARN_ADD([-funit-at-a-time]) + # Need -fipa-pure-const in order to make -Wsuggest-attribute=pure + # fire even without -O. + gl_WARN_ADD([-fipa-pure-const]) + # We should eventually enable this, but right now there are at + # least 75 functions triggering warnings. + gl_WARN_ADD([-Wno-suggest-attribute=pure]) + gl_WARN_ADD([-Wno-suggest-attribute=const]) + if test "$enable_compile_warnings" = "error" then gl_WARN_ADD([-Werror]) -- 1.7.7.3

[libvirt] [PATCH 1/1] apparmor: allow tunnelled migrations.
by Serge Hallyn 02 Dec '11

02 Dec '11

The pathname for the pipe for tunnelled migration is unresolvable. The libvirt apparmor driver therefore refuses access, causing migration to fail. If we can't resolve the path, the worst that can happen is that we should have given permission to the file but didn't. Otherwise (especially since this is a /proc/$$/fd/N file) the file is already open and libvirt won't be refused access by apparmor anyway. Also adjust virt-aa-helper to allow access to the *.tunnelmigrate.dest.name files. Changelog: Dec 2: per jdstrand comment, also change the Error to a VIR_WARN.

[libvirt] [PATCH] client: Check if other thread claims it has the buck before claiming it.
by Peter Krempa 02 Dec '11

02 Dec '11

Originaly, the code checked if another client is the queue and infered ownership of the buck from that. Commit fa9595003d043df9f2efe95521c008 added a separate variable to track the buck. That caused, that a new call might enter claiming it has the buck, while another thread was signalled to take the buck. This ends in two threads claiming they hold the buck and entering poll().

[libvirt] [RFC v3 PATCH 0/5] PowerPC : Extend libvirt for the PowerPC-KVM platform
by Prerna Saxena 02 Dec '11

02 Dec '11

Recent development in KVM for 64-bit Power ISA Book3S machines, allows users to run multiple KVM guest instances on POWER7 and PPC970 processor based systems. Also qemu-system-ppc64 has been enhanced to support a new machine type "pseries" suitable for Power Book3S machines. This addition effectively brings the KVM+qemu combination to run multiple guest instances on a Power Book3S machine. Libvirt continues to be the key interface to configure and manage the KVM guest instances on x86. This patch set is an effort to enable libvirt to support KVM guest configuration and management on Power Book3S machines. Based on community discussion around the earlier version, this patch series augments the present 'kvm' driver to support PowerPC-KVM based guests.Since some of the supported devices vary between architectures, libvirt must be capable of choosing supported device backends and defaults for each architecture in qemu. To check if qemu supports a certain feature, libvirt at present parses the -help string which is generated by running the qemu binary with the '-h' argument. This approach is gated by QEMU's inherent limitation. When generating the list of allowed options with the '-h' flags, qemu today blindly lists all options defined for any architecture/platform instead of doing any arch-specific checking. This tricks libvirt into assuming a much bigger set of host capabilities than is actually available. Ideally, it would be good to have qemu specify a list of devices for a given architecture and platform which libvirt can parse to understand supported capabilities for that guest. As a part of this patchset, there is an attempt to cleanly bifurcate libvirt code and to remove x86-specific assumptions from generic qemu commandline code. Series Description: ------------------- This patch series consists of 5 patches : Patch 1/5 : Use sysfs to gather host topology in place of /proc/cpuinfo. Patch 2/5 : Add PowerPC CPU Driver Patch 3/5 : Add support for qemu-system-ppc64 Patch 4/5 : Clean up x86-specific assumptions from generic qemu code. Patch 5/5 : Add address family "spapr-vio" Changelog: --------- ** v1->v2 : * Patches 1,2,3 unchanged ; The hacks in Patch 4 of v1 replaced by a new patch to neatly select arch-specific features. ** v2->v3 : * Patches 1,2,3 have minor cleanups ; Patch 4 no longer has an arch-specific handler routine. It is now replaced by a much simpler patch that merely removes x86/pc-specific assumptions from libvirt. ** v3->v4 : * Patches 1,2,3,4 unchanged ; patch 5 is a new addition from Michael Ellerman that adds a new device-tree based addressing mechanism for the 'pseries' guest. -- Prerna Saxena Linux Technology Centre, IBM Systems and Technology Lab, Bangalore, India

[libvirt] [RFC v4 PATCH 0/5] PowerPC : Extend libvirt to use PowerPC-KVM platform
by Prerna Saxena 02 Dec '11

02 Dec '11

Libvirt continues to be the key interface to configure and manage the KVM guest instances on x86. This patch set is an effort to enable libvirt to support KVM guest configuration and management on Power Book3S machines. Based on community discussion around the earlier version, this patch series augments the present 'kvm' driver to support PowerPC-KVM based guests. With the CPU driver for PowerPC already merged, this patch series adds on clean-ups, and some test cases as suggested. This series mostly focuses on cleanup and addition of testcases for base- powerpc patches. The patches for enabling spapr-vio based addressing would be sent out shortly, with the right domain schema additions. Series description: ------------------- Patch 1/5 : Use sysfs to decipher cpu topology information. Patch 2/5 : Modify the tests/nodeinfotest.c to use sysfs in addition to proc/cpuinfo. Patch 3/5 : Add support for ppc64 qemu Patch 4/5 : Clean up qemuBuildCommandLine to remove x86-specific assumptions. Patch 5/5 : Add ppc64 specific definitions to domain.rng Changelog: ---------- ** v1->v2 : * Patches 1,2,3 unchanged ; The hacks in Patch 4 of v1 replaced by a new patch to neatly select arch-specific features. ** v2->v3 : * Patches 1,2,3 have minor cleanups ; Patch 4 no longer has an arch-specific handler routine.

Patch 5 is a new addition from Michael Ellerman that adds a new device-tree based addressing mechanism for the 'pseries' guest. ** v3->v4 : * Patch 1 has minor cleanups, Patch 2 is a new addition that introduces test cases for patch 1. Patch 3,4 also have minor cleanups Patch 5 is a new addition, it contains ppc64 specific definitions to domain.rng -- Prerna Saxena Linux Technology Centre, IBM Systems and Technology Lab, Bangalore, India

[libvirt] [PATCH 0/2] gnulib update
by Eric Blake 01 Dec '11

01 Dec '11

The latest gnulib update accidentally reintroduced -Wformat-nonliteral (by virtue of adding -Wformat=2, understood only by newer gcc), I almost got sucked into the rathole of fixing all our problems before I realized the real issue, but by then, I had already written patch 1. I'd like to get this in before the freeze, and then (hopefully) not touch .gnulib until after the release (we've been burned too many times by a .gnulib update after rc1).

[libvirt] [PATCH] build: fix 'make dist' without dtrace
by Eric Blake 01 Dec '11

01 Dec '11

probes.h can only be generated on Linux, and then only with dtrace installed. If it is part of the tarball, then either 'make dist' will fail if you don't have that setup, or we would have to start keeping probes.h in libvirt.git. Since we only need it to be generated when dtrace is in use, it's better to avoid shipping it in the first place, and avoid tracking it in git. Meanwhile, there is a build dependency - since the RPC code is generated, it can be built early; but when dtrace is enabled, we must ensure probes.h is built even earlier. Commit 1afcfbdd tried to fix this, but did so in a way that added probes.h into the tarball, and broke VPATH as well. Commit ecbca767 fixed VPATH, but didn't fix the more fundamental problem. This patch solves the issue by adding a dependency instead. Tested with 'make dist' in a clean VPATH builds, for both './configure --without-dtrace' and './configure --with-dtrace'; all configurations were able to correctly build a tarball, and the dtrace configuration no longer sticks probes.h in the tarball. * src/Makefile.am (REMOTE_DRIVER_GENERATED): Don't ship probes.h; rather, make it a dependency. --- Pushing under the build-breaker rule, since I reproduced a failure with './configure --without-dtrace && make dist' without this patch. src/Makefile.am | 9 +++------ 1 files changed, 3 insertions(+), 6 deletions(-) diff --git a/src/Makefile.am b/src/Makefile.am index 4c98397..93bf54c 100644 --- a/src/Makefile.am +++ b/src/Makefile.am @@ -202,11 +202,6 @@ REMOTE_DRIVER_GENERATED = \ $(srcdir)/remote/qemu_protocol.h \ $(srcdir)/remote/qemu_client_bodies.h -# The remote RPC driver needs probes.h -if WITH_DTRACE -REMOTE_DRIVER_GENERATED += probes.h -endif - REMOTE_PROTOCOL = $(srcdir)/remote/remote_protocol.x QEMU_PROTOCOL = $(srcdir)/remote/qemu_protocol.x REMOTE_DRIVER_PROTOCOL = $(REMOTE_PROTOCOL) $(QEMU_PROTOCOL) @@ -646,7 +641,6 @@ libvirt_driver_remote_la_LDFLAGS += -module -avoid-version endif libvirt_driver_remote_la_SOURCES = $(REMOTE_DRIVER_SOURCES) - $(srcdir)/remote/remote_driver.c: $(REMOTE_DRIVER_GENERATED) endif WITH_REMOTE @@ -1283,6 +1277,9 @@ if WITH_DTRACE libvirt_la_BUILT_LIBADD += probes.o libvirt_la_DEPENDENCIES += probes.o nodist_libvirt_la_SOURCES = probes.h +if WITH_REMOTE +$(REMOTE_DRIVER_GENERATED): probes.h +endif WITH_REMOTE BUILT_SOURCES += probes.h libvirt_probes.stp libvirt_functions.stp -- 1.7.7.3

Hi, I'm working on updating PHP to 5.4.0 (probably a fedora 17 feature). libvirt 0.4.5 doesn't build because function_entry have been removed See http://news.php.net/php.pecl.dev/7123 Fix is trivial : s/function_entry/zend_function_entry/ Attcached patch solves this issue and also fixes a lot of compiler warning (unused variable, unset, ...) There is still a lot of warning... (most are trivial to fix) I Hope this helps. Remi. P.S.

[libvirt] [PATCH] virsh: Allow other escape characters for console
by Michal Privoznik 01 Dec '11

01 Dec '11

Currently virsh supports only ^] as escape character for console. However, some users might want to use something else. This patch creates such ability by specifying '-e' switch on virsh command line. --- Okay, this patch is meant as RFC mainly but if it got enough ACKs I will not hesitate to push it. My biggest concern is the way of telling virsh customized sequence. I am not big fan of new switch, however we lack virsh.conf in $conf_dir. Maybe it is the right time for creating it. Another approach is to pass the sequence as parameter directly to 'console' command.

[libvirt] [PATCHv6 0/7] block io throttle via per-device block IO tuning

Here's the latest state of Lei's patch series with all my comments folded in. I may have a few more tweaks to make now that I'm at the point of testing things with both old qemu (graceful rejection) and new qemu (sensical return values), so it may be a day or two (or even a weekend, since this is a holiday weekend for me) before I actually push this, so it wouldn't hurt if anyone else wants to review in the meantime.

[libvirt] [PATCH] spec: mark directories in /var/run as ghosts
by Eric Blake 01 Dec '11

01 Dec '11

We have several directories that are created on the fly, and which only contain state relevant to a running libvirtd process (all located in /var/run). Since the directories are created as needed, and make no sense without a running libvirtd, we want them deleted if libvirt is uninstalled. And in F15 and newer, /var/run is on tmpfs (forcing us to recreate on the fly); which means that someone trying to verify a complete rpm will fail if the directory does not currently exist because libvirtd has not been started since boot. The solution, then, is to mark the directories as %ghost, so that rpm knows that we own them and will clean it up if libvirt is uninstalled, but will no longer create the directory for us at install, nor complain at verify time if the directory does not exist. See https://bugzilla.redhat.com/show_bug.cgi?id=656611. * libvirt.spec.in (%files): Add %ghost to temporary directories that we don't install, but want cleaned up on libvirt removal. --- libvirt.spec.in | 12 ++++++------ 1 files changed, 6 insertions(+), 6 deletions(-) diff --git a/libvirt.spec.in b/libvirt.spec.in index f61a243..06c949b 100644 --- a/libvirt.spec.in +++ b/libvirt.spec.in @@ -1082,7 +1082,7 @@ rm -f $RPM_BUILD_ROOT%{_sysconfdir}/sysctl.d/libvirtd %{_datadir}/libvirt/networks/default.xml %endif -%dir %{_localstatedir}/run/libvirt/ +%ghost %dir %{_localstatedir}/run/libvirt/ %dir %attr(0711, root, root) %{_localstatedir}/lib/libvirt/images/ %dir %attr(0711, root, root) %{_localstatedir}/lib/libvirt/filesystems/ @@ -1090,24 +1090,24 @@ rm -f $RPM_BUILD_ROOT%{_sysconfdir}/sysctl.d/libvirtd %dir %attr(0711, root, root) %{_localstatedir}/cache/libvirt/ %if %{with_qemu} -%dir %attr(0700, root, root) %{_localstatedir}/run/libvirt/qemu/ +%ghost %dir %attr(0700, root, root) %{_localstatedir}/run/libvirt/qemu/ %dir %attr(0750, %{qemu_user}, %{qemu_group}) %{_localstatedir}/lib/libvirt/qemu/ %dir %attr(0750, %{qemu_user}, %{qemu_group}) %{_localstatedir}/cache/libvirt/qemu/ %endif %if %{with_lxc} -%dir %{_localstatedir}/run/libvirt/lxc/ +%ghost %dir %{_localstatedir}/run/libvirt/lxc/ %dir %attr(0700, root, root) %{_localstatedir}/lib/libvirt/lxc/ %endif %if %{with_uml} -%dir %{_localstatedir}/run/libvirt/uml/ +%ghost %dir %{_localstatedir}/run/libvirt/uml/ %dir %attr(0700, root, root) %{_localstatedir}/lib/libvirt/uml/ %endif %if %{with_libxl} -%dir %{_localstatedir}/run/libvirt/libxl/ +%ghost %dir %{_localstatedir}/run/libvirt/libxl/ %dir %attr(0700, root, root) %{_localstatedir}/lib/libvirt/libxl/ %endif %if %{with_network} -%dir %{_localstatedir}/run/libvirt/network/ +%ghost %dir %{_localstatedir}/run/libvirt/network/ %dir %attr(0700, root, root) %{_localstatedir}/lib/libvirt/network/ %dir %attr(0755, root, root) %{_localstatedir}/lib/libvirt/dnsmasq/ %endif -- 1.7.7.3

[libvirt] [libvirt-glib] Fix potential race in GVirObjectConnection::domain_event_cb
by Christophe Fergeau 30 Nov '11

30 Nov '11

This method starts by looking up a domain in priv->domains, and later, depending on the kind of event that occurred, it may remove this domain from priv->domains. While the individual operations (lookup, removal) are protected by priv->lock, there is no guarantee that the looked up domain and even priv->domains will stay unchanged when priv->lock isn't held. In particular, gvir_connection_close will destroy priv->domains which will unreference all the domains it contains (potentially destroying them too), and gvir_connection_fetch_domains will change priv->domains value. To avoid these issues, this commit takes a reference on priv->domains so that it doesn't get away behind our back, and it takes a reference on the looked up domain too to ensure it stays alive for the duration of domain_event_cb run. --- libvirt-gobject/libvirt-gobject-connection.c | 17 +++++++++++------ 1 files changed, 11 insertions(+), 6 deletions(-) diff --git a/libvirt-gobject/libvirt-gobject-connection.c b/libvirt-gobject/libvirt-gobject-connection.c index 59b828d..786a026 100644 --- a/libvirt-gobject/libvirt-gobject-connection.c +++ b/libvirt-gobject/libvirt-gobject-connection.c @@ -257,6 +257,7 @@ static int domain_event_cb(virConnectPtr conn G_GNUC_UNUSED, void *opaque) { gchar uuid[VIR_UUID_STRING_BUFLEN]; + GHashTable *doms; GVirConnection *gconn = opaque; GVirDomain *gdom; GVirConnectionPrivate *priv = gconn->priv; @@ -269,14 +270,18 @@ static int domain_event_cb(virConnectPtr conn G_GNUC_UNUSED, g_debug("%s: %s event:%d, detail:%d", G_STRFUNC, uuid, event, detail); g_mutex_lock(priv->lock); - gdom = g_hash_table_lookup(priv->domains, uuid); + doms = g_hash_table_ref(priv->domains); + gdom = g_hash_table_lookup(doms, uuid); + if (gdom != NULL) + g_object_ref(G_OBJECT(gdom)); g_mutex_unlock(priv->lock); if (gdom == NULL) { gdom = GVIR_DOMAIN(g_object_new(GVIR_TYPE_DOMAIN, "handle", dom, NULL)); g_mutex_lock(priv->lock); - g_hash_table_insert(priv->domains, (gpointer)gvir_domain_get_uuid(gdom), gdom); + g_hash_table_insert(doms, (gpointer)gvir_domain_get_uuid(gdom), + g_object_ref(G_OBJECT(gdom))); g_mutex_unlock(priv->lock); } @@ -293,11 +298,10 @@ static int domain_event_cb(virConnectPtr conn G_GNUC_UNUSED, case VIR_DOMAIN_EVENT_UNDEFINED: if (detail == VIR_DOMAIN_EVENT_UNDEFINED_REMOVED) { g_mutex_lock(priv->lock); - g_hash_table_steal(priv->domains, uuid); + g_hash_table_remove(doms, uuid); g_mutex_unlock(priv->lock); g_signal_emit(gconn, signals[VIR_DOMAIN_REMOVED], 0, gdom); - g_object_unref(gdom); } else g_warn_if_reached(); break; @@ -365,11 +369,10 @@ static int domain_event_cb(virConnectPtr conn G_GNUC_UNUSED, if (virDomainIsPersistent(dom) != 1) { g_mutex_lock(priv->lock); - g_hash_table_steal(priv->domains, uuid); + g_hash_table_remove(doms, uuid); g_mutex_unlock(priv->lock); g_signal_emit(gconn, signals[VIR_DOMAIN_REMOVED], 0, gdom); - g_object_unref(gdom); } break; @@ -377,6 +380,8 @@ static int domain_event_cb(virConnectPtr conn G_GNUC_UNUSED, g_warn_if_reached(); } + g_object_unref(G_OBJECT(gdom)); + g_hash_table_unref(doms); return 0; } -- 1.7.7.3

[libvirt] Associate a LUN as disk with WWNN/WWPN
by Osier Yang 30 Nov '11

30 Nov '11

Hi, all This is a rough thought about how to allow the user to associate a LUN as disk with WWNN/WWPN. Never mind if some thought is complete wrong, I'm complete new to this area. :-) The initial idea was to introduce new XML for the vHBA which the LUN which be assisned to in a domain XML, just like comment #2 of RHBZ# 543037: <quote> AFAIU libvirt needs a way to: - Associate a virtual adapter WWN with a VM (in the VM xml) - Learn to start a virtual adapter when the VM is started, and destroy the adapter when the VM is stopped. - Possibly a way to associate a WWN with a scsi pool, to start / stop a virtual adapter with the pool. </quote> But afer thinking more, I'd think it might be not good idea: As far as I could understand, the requirement of the BZ wants a way to create/migrate a guest with NPIV. I'm goint to talk create first,and migration then. === Creation If we try to support this all inside libvirt, it means we need to new XML for indicates the WWNN/WWPN of the vHBA or Physical HBA, this is fine we can do it, though it's a bit annoyed where to add it. The biggest problem is there is a race here, we can't known the path of the LUN unless the storage admin assigned (zone / mask, will already use assign for brevity) a LUN to the (v)HBA, and it appears on host successfully. However, domain define/create doesn't allow the disk source path be empty, except it's CDROM, or Floppy. The works which need to be done before domain define should be: - If the user wants to create new vHBA. 1) auto-generate /or specify WWNN/WWPN (with Qumranet's OUI: 00-1A-4A) 2) allows to select fabric WWN, (to guide the choice of which FC adapter to select for the Vport creation, assuming different adapters connect to different fabrics) 3) create the vHBA with virNodeDeviceCreateXML API 4) Ask / prompt the user to ask the storage admin assigns the LUN to the vHBA. 5) Waits for the LUN shows up on host (perhaps via storage pool API) 6) Use the LUN's path (e.g. /dev/disk/by-id/scsi-3600c0ff000d7a2a5d163ff4490100000000-part1) as the disk source path. - If the user wants to select a existed (v)HBA. 1), 2) and 3) are ommited 3) and 4) might be also ommited if there is a LUN already assigned to the selected (v)HBA. As we can see, there are lots of interaction. If we simply wants to do all these work inside libvirt, we lose the user friendly interaction, and just makes our life harder. So, I would these work should be done in external / upper apps, e.g. virt-manager, or Boxes in future. What libvirt needs to do (as far as I could get): 1) support the fabric WWN in node device XML 2) may be we can do auto-generating the WWNN/WWPN inside libvirt if they are not specified. But from a user's p.o.v, I'd see it is in UI, but not in codes silently. 3) perhaps provides methods to get the (v)HBA's fabric's WWN? === Migration If we do things as explained above for domain's creation, the disk XML will be like: <disk type='disk' device='disk'> <driver name='qemu' type='raw'/> <source file='/dev/disk/by-id/scsi-3600c0ff000d7a2a5d163ff4490100000000-part1/'> <target dev='vda' bus='virtio'/> <alias name='virtio-disk0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03 function='0x0'/> </disk> It's just similiar with disk which uses a normal disk image. So we needs to something to indentify it's special, it's a LUN assigned to a (v)HBA. Ways to do that in my mind are: 1) If we could find the WWNN/WWPN/fabricwwn by the LUN's path, (I'm not sure if there is a good way yet), things will be much simpler, what we need might be just a simple flag to tell the disk source path is LUN assigned to (v)HBA. e.g. <source file='$path_of_lun' type='fc_hba'/> 2) if there is no way to get the WWNN/WWPN/fabricwwn by LUN's path, we might need the whole config of (v)HBA. e.g. <souce protocol='fc' file='$path_of_lun'> <hba> <wwnn>$wwnn</wwnn> <wwpn>$wwpn</wwpn> <fabricwwn>$fabricwwn</fabricwwn> </hba> </source> And then in virt-manager or Boxes, it needs to detect if there is disk use FC LUN, if it's it should teach dest libvirt to create another vHBA, and assign the same LUN to it. Then migration could do just as normal. But problem of doing like so is the migration won't work anyway with virsh. Hmmm, /me thinking if it will be disireable to introduce hook support for migration. Things will be much simpler if we support hooks? Thoughts and Opinions? Regards, Osier

[libvirt] [libvirt-glib] gir: use libraries from build tree, not installed ones

If we don't explicitly mention path to our uninstalled libraries to g-ir-scanner, it will use installed libvirt-* libraries instead of the ones we just built to run a binary during the generation of the gir file. However this binary will have been compiled with the uninstalled ones, This is an issue if the installed libraries are not ABI compatible with the uninstalled one, and will cause a compile failure because the binary will fail to run.

[libvirt] [PATCH 0/5] Interface pools and passthrough mode
by Shradha Shah 29 Nov '11

29 Nov '11

Interface Pools and Passthrough mode: Current Method: The passthrough mode uses a macvtap âdirectâ connection to connect each guest to the network. The physical interface to be used is picked from among those listed in <interface> sub elements of the <forward> element. The current specification for <forward> extends to allow 0 or more <interface> sub-elements: Example: <forward mode='passthrough' dev='eth10'/> <interface dev='eth10'/> <interface dev='eth12'/> <interface dev='eth18'/> <interface dev='eth20'/> </forward> However with an ethernet card with 64 VF's or more, the above method gets tedious on the system. On the other hand, just parameterizing a string (eth%d) is inadequate, eg, when there are multiple non-contiguous ranges. Proposed Method: The 5 patches provided along with this introductory e-mail i) Introduce a structure to store the state of all the virtual functions attached to each physical function ii) Find a free virtual function given the physical function. The forward specification will hence only mention the physical function as the interface sub element: Example: <forward mode='passthrough' dev='eth2'/> <interface dev='eth2'/> </forward> Shradha Shah (5): Moving the declaration of _pciDevice and _pciDeviceList to pci.h Added function pciSysfsFile to enable access to the PCI SYSFS files. Adding functions virNetDevGetVirtualFunctions and virNetDevGetNetName virNetDevGetVirtualFunctions: Gets the BDF of all the Virtual Functions given a physical function virNetDevGetNetName: Gets the interface name of the PCI Device. Addition of a new device structure to store the state of a Virtual Function Modifications to the Physical Device Structure to store state of its Virtual Functions If a system has 64 or more VF's, it is quite tedious to mention each VF in the interface pool. The following modification find a Free VF given a Physical Function when mode=passthrough. We also save the state of each VF. Hence modifications to networkAllocateActualDevice, networkNotifyActualDevice and networkReleaseActualDevice were required.

[libvirt] [PATCH 0/3] Improve async signal safety of timestamp APIs
by Daniel P. Berrange 29 Nov '11

29 Nov '11

There are rare reports of libvirt deadlocking itself which show a fork'd, but not exec'd, child process stuck in localtime_r(). This is because localtime_r() is not an async signal, so if we happened to fork() at the exact time another thread was calling localtime_r() we could get stuck with a stale lock in the child. Although we go to pains to protect the libvirt logging code by acquiring the mutex before forking, this is not sufficient, because some non-logging related code could invoke virTimestamp() which calls localtime_r() too. The only sane approach to fix this is to make our timestamp generation APIs thread safe, by doing a clean impl of gmtime() and strftime() inside libvirt using static buffers and only async safe POSIX apis.

This patch won't be any good without defining proper fine-grained log domains though. http://blogs.gnome.org/mclasen/2011/11/09/better-logging/ --- examples/event-test.c | 4 +-- libvirt-gconfig/libvirt-gconfig-capabilities.c | 6 +---- libvirt-gconfig/libvirt-gconfig-domain-clock.c | 6 +---- libvirt-gconfig/libvirt-gconfig-domain-device.c | 6 +---- libvirt-gconfig/libvirt-gconfig-domain-disk.c | 6 +---- .../libvirt-gconfig-domain-graphics-spice.c | 6 +---- libvirt-gconfig/libvirt-gconfig-domain-graphics.c | 6 +---- libvirt-gconfig/libvirt-gconfig-domain-input.c | 6 +---- .../libvirt-gconfig-domain-interface-network.c | 6 +---- libvirt-gconfig/libvirt-gconfig-domain-interface.c | 6 +---- libvirt-gconfig/libvirt-gconfig-domain-os.c | 6 +---- libvirt-gconfig/libvirt-gconfig-domain-snapshot.c | 6 +---- libvirt-gconfig/libvirt-gconfig-domain-timer.c | 6 +---- libvirt-gconfig/libvirt-gconfig-domain-video.c | 6 +---- libvirt-gconfig/libvirt-gconfig-domain.c | 6 +---- libvirt-gconfig/libvirt-gconfig-interface.c | 6 +---- libvirt-gconfig/libvirt-gconfig-network-filter.c | 6 +---- libvirt-gconfig/libvirt-gconfig-network.c | 6 +---- libvirt-gconfig/libvirt-gconfig-node-device.c | 6 +---- libvirt-gconfig/libvirt-gconfig-object.c | 10 +------ libvirt-gconfig/libvirt-gconfig-secret.c | 6 +---- libvirt-gconfig/libvirt-gconfig-storage-pool.c | 6 +---- libvirt-gconfig/libvirt-gconfig-storage-vol.c | 6 +---- libvirt-glib/libvirt-glib-event.c | 26 ++++++++----------- libvirt-glib/libvirt-glib-main.c | 10 +------- libvirt-gobject/libvirt-gobject-connection.c | 12 +++------ libvirt-gobject/libvirt-gobject-domain-device.c | 8 +---- libvirt-gobject/libvirt-gobject-domain-disk.c | 8 +---- libvirt-gobject/libvirt-gobject-domain-interface.c | 8 +---- libvirt-gobject/libvirt-gobject-domain-snapshot.c | 8 +---- libvirt-gobject/libvirt-gobject-domain.c | 8 +---- libvirt-gobject/libvirt-gobject-input-stream.c | 6 +---- libvirt-gobject/libvirt-gobject-interface.c | 8 +---- libvirt-gobject/libvirt-gobject-main.c | 8 ------ libvirt-gobject/libvirt-gobject-manager.c | 8 +---- libvirt-gobject/libvirt-gobject-network-filter.c | 8 +---- libvirt-gobject/libvirt-gobject-network.c | 8 +---- libvirt-gobject/libvirt-gobject-node-device.c | 8 +---- libvirt-gobject/libvirt-gobject-output-stream.c | 6 +---- libvirt-gobject/libvirt-gobject-secret.c | 8 +---- libvirt-gobject/libvirt-gobject-storage-pool.c | 8 +---- libvirt-gobject/libvirt-gobject-storage-vol.c | 8 +---- libvirt-gobject/libvirt-gobject-stream.c | 6 +---- 43 files changed, 69 insertions(+), 249 deletions(-) diff --git a/examples/event-test.c b/examples/event-test.c index fdd70bf..4fb000e 100644 --- a/examples/event-test.c +++ b/examples/event-test.c @@ -6,8 +6,6 @@ #include <libvirt/libvirt.h> #include <libvirt-glib/libvirt-glib.h> -#define DEBUG0(fmt) printf("%s:%d :: " fmt "\n", __FUNCTION__, __LINE__) -#define DEBUG(fmt, ...) printf("%s:%d: " fmt "\n", __FUNCTION__, __LINE__, __VA_ARGS__) #define STREQ(a,b) (strcmp((a),(b)) == 0) #ifndef ATTRIBUTE_UNUSED @@ -171,7 +169,7 @@ int main(int argc, char **argv) return -1;

[libvirt] [ PATCH v5 0/4] API to invoke S3/S4 on a host and also resume from within libvirt
by Srivatsa S. Bhat 29 Nov '11

29 Nov '11

This patchset adds a new API to put a host to a suspended state (Suspend-to-RAM, Suspend-to-Disk or Hybrid-Suspend) and setup a timed resume to get the host back online, from within libvirt. This uses the RTC wakeup mechanism to set up a timer alarm before suspending the host, so that in-band resume is facilitated by the firing of the RTC alarm, which wakes up the host. This patch applies on top of the Hybrid-Suspend patch posted in [1]. v5: * Added MIN_TIME_REQ_FOR_SUSPEND. * Incorporated the review comments in [3]. v4: * Applies on top of the Hybrid-Suspend patch posted in [1]. * Incorporated the review comments in [2]. v3: * Rebased to libvirt 0.9.7 * Added a check to see if alarmTime (suspend duration) is within an acceptable range. v2: * Added an init function which finds out if S3/S4 is supported by the host, upon the first request to suspend/hibernate. * Added synchronization/locking to ensure that only one suspend operation is active at a time. v1: http://www.redhat.com/archives/libvir-list/2011-September/msg00830.html v2: http://comments.gmane.org/gmane.comp.emulators.libvirt/46729 References: [1]. http://www.redhat.com/archives/libvir-list/2011-November/msg01407.html [2]. http://thread.gmane.org/gmane.comp.emulators.libvirt/47950 [3]. http://thread.gmane.org/gmane.comp.emulators.libvirt/49054 Srivatsa S.

[libvirt] [PATCH] Add 'Hybrid-Suspend' power management discovery for the host
by Srivatsa S. Bhat 29 Nov '11

29 Nov '11

Some systems support a feature known as 'Hybrid-Suspend', apart from the usual system-wide sleep states such as Suspend-to-RAM (S3) or Suspend-to-Disk (S4). Add the functionality to discover this power management feature and export it in the capabilities XML under the <power_management> tag. This addition was suggested in [1].

[libvirt] [RFC PATCH 0/5] Support online resizing of block devices.
by Osier Yang 28 Nov '11

28 Nov '11

This patch series introduce new API "virDomainBlockResize" to expose qemu monitor command "block_size", which is for resizing the a block device while the domain is running. The prototype for the new API is: int virDomainBlockResize (virDomainPtr dom, const char *path, unsigned long long size, unsigned int flags) * "@path" is the absolute path of the block device, which can be extraced from domain xml. * The units for "@size" is kilobytes, which might be not quite properly. (qemu HMP uses Megabytes as the default units, QMP uses Bytes as the default units, so it means we need to divice "@size" by 1024 for HMP, and multiply "@size" by 1024 for QMP. On the other hand, we need to check the overflowing). Any ideas on this is welcomed. * "@flags" is unused currently. [PATCH 1/5] block_resize: Define the new API [PATCH 2/5] block_resize: Wire up the remote protocol [PATCH 3/5] block_resize: Implement qemu monitor functions [PATCH 4/5] block_resize: Implement qemu driver method [PATCH 5/5] block_resize: Expose the new API to virsh

[libvirt] [ PATCH v4 0/4] API to invoke S3/S4 on a host and also resume from within libvirt
by Srivatsa S. Bhat 28 Nov '11

28 Nov '11

This patchset adds a new API to put a host to a suspended state (Suspend-to-RAM, Suspend-to-Disk or Hybrid-Suspend) and setup a timed resume to get the host back online, from within libvirt. This uses the RTC wakeup mechanism to set up a timer alarm before suspending the host, so that in-band resume is facilitated by the firing of the RTC alarm, which wakes up the host. The decision to use the RTC Wakeup mechanism to resume the host from sleep was taken in [1]. An initial API was discussed in [2]. Some design ideas for the asynchronous mechanism implementation was discussed in [3]. v4: * Applies on top of the Hybrid-Suspend patch posted in [4]. * Incorporated the review comments in [5]. v3: * Rebased to libvirt 0.9.7 * Added a check to see if alarmTime (suspend duration) is within an acceptable range. v2: * Added an init function which finds out if S3/S4 is supported by the host, upon the first request to suspend/hibernate. * Added synchronization/locking to ensure that only one suspend operation is active at a time. v1: http://www.redhat.com/archives/libvir-list/2011-September/msg00830.html v2: http://comments.gmane.org/gmane.comp.emulators.libvirt/46729 References: [1]. http://www.redhat.com/archives/libvir-list/2011-August/msg00327.html [2]. http://www.redhat.com/archives/libvir-list/2011-August/msg00248.html [3]. http://www.redhat.com/archives/libvir-list/2011-September/msg00438.html [4]. http://www.redhat.com/archives/libvir-list/2011-November/msg01407.html [5]. http://thread.gmane.org/gmane.comp.emulators.libvirt/47950 Srivatsa S.

[libvirt] [PATCH] Change security driver APIs to use virDomainDefPtr instead of virDomainObjPtr
by Daniel P. Berrange 28 Nov '11

28 Nov '11

From: "Daniel P. Berrange" <berrange(a)redhat.com> When sVirt is integrated with the LXC driver, it will be neccessary to invoke the security driver APIs using only a virDomainDefPtr since the lxc_container.c code has no virDomainObjPtr available. Aside from two functions which want obj->pid, every bit of the security driver code only touches obj->def. So we don't need to pass a virDomainObjPtr into the security drivers, a virDomainDefPtr is sufficient. Two functions also gain a 'pid_t pid' argument. * src/qemu/qemu_driver.c, src/qemu/qemu_hotplug.c, src/qemu/qemu_migration.c, src/qemu/qemu_process.c, src/security/security_apparmor.c, src/security/security_dac.c, src/security/security_driver.h, src/security/security_manager.c, src/security/security_manager.h, src/security/security_nop.c, src/security/security_selinux.c, src/security/security_stack.c: Change all security APIs to use a virDomainDefPtr instead of virDomainObjPtr --- src/qemu/qemu_driver.c | 10 +- src/qemu/qemu_hotplug.c | 28 ++-- src/qemu/qemu_migration.c | 12 +- src/qemu/qemu_process.c | 24 ++-- src/security/security_apparmor.c | 136 ++++++++++---------- src/security/security_dac.c | 91 +++++++------- src/security/security_driver.h | 36 +++--- src/security/security_manager.c | 40 +++--- src/security/security_manager.h | 36 +++--- src/security/security_nop.c | 36 +++--- src/security/security_selinux.c | 258 +++++++++++++++++++------------------- src/security/security_stack.c | 44 ++++--- 12 files changed, 384 insertions(+), 367 deletions(-) diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index 6cfdd1d..6e001ce 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -3096,7 +3096,7 @@ qemuDomainScreenshot(virDomainPtr dom, } unlink_tmp = true;

[libvirt] [PATCH] storage: Refetch file status after open
by Michal Privoznik 28 Nov '11

28 Nov '11

This partly reverts my previous patch f88de3eb. We need to get file status after open, as given path could have been symlink, so fstat() will operate on different file than lstat(). --- src/storage/storage_backend.c | 8 ++++++++ 1 files changed, 8 insertions(+), 0 deletions(-) diff --git a/src/storage/storage_backend.c b/src/storage/storage_backend.c index d30829d..d7394e0 100644 --- a/src/storage/storage_backend.c +++ b/src/storage/storage_backend.c @@ -1041,6 +1041,14 @@ virStorageBackendVolOpenCheckMode(const char *path, unsigned int flags) return -1; } + if (fstat(fd, &sb) < 0) { + virReportSystemError(errno, + _("cannot stat file '%s'"), + path); + VIR_FORCE_CLOSE(fd); + return -1; + } + if (S_ISREG(sb.st_mode)) mode = VIR_STORAGE_VOL_OPEN_REG; else if (S_ISCHR(sb.st_mode)) -- 1.7.3.4

[libvirt] VBOX driver : "An error occurred, but the cause is unknown" when trying to start a Virtualbox domain
by Jean-Christophe Guillain 28 Nov '11

28 Nov '11

Hello, I opened a bug (http://bugzilla.redhat.com/show_bug.cgi?id=757138) about this issue, but I was told to mention it to this list too. Here is my problem : when I try to start a virtualbox domain with virsh, an error occurs. (But when the domain is started using Virtualbox GUI it works, and I have no problem to stop it with virsh...) Example : virsh # start freenas1 error: Failed to start domain freenas1 error: An error occurred, but the cause is unknown I use libvirt 0.9.2-7 and virtualbox 4.0.10 on a Debian with 2.6.32-5-amd64 kernel. The XML config file of the domain : <domain type='vbox' id='1'> <name>freenas1</name> <uuid>07aadf11-2090-4690-9518-52766722c544</uuid> <memory>524288</memory> <currentMemory>524288</currentMemory>

Malloc page than realloc to smaller does not work ?

Providing a posix_memalign_free defeats the purpose - POSIX requires that plain free() will cover the memory returned by posix_memalign. The list of platforms missing posix_memalign is a bit daunting: MacOS X 10.5, FreeBSD 6.0, NetBSD 3.0, OpenBSD 3.8, Minix 3.1.8, AIX 5.1, HP-UX 11, IRIX 6.5, OSF/1 5.1, Solaris 10, Cygwin 1.5.x, mingw, MSVC 9, Interix 3.5, BeOS. but what would be interesting to know is how many of those platforms return page-aligned pointers for any malloc() request of a page or more of memory. That is, we may be able to coerce malloc into aligned results by over-allocating and over-aligning the user's request, if the system malloc() has at least one mode of returning page-aligned memory. Another alternative is to override free() at the same time as providing posix_memalign(). The gnulib malloca module provides a freea() function that can distinguish whether it is paired with an alloca() (nop) or mmalloca() (call the real free()), by over-allocating and probing for a magic header. Similar concepts could be used in writing an rpl_free() that determines whether it was allocated by posix_memalign(): if we guarantee that posix_memalign always returns something aligned to at least a page, then rpl_free() can make a quick check for whether the pointer passed in is page-aligned; if so, do a hash lookup to see if it was a page reserved by our posix_memalign (if so, we know the real address to free); if not or the hash lookup fails, it came from malloc (in which case, regular free should work). Of course, unlike freea() that probes for a magic header, we can't safely probe a header by crossing page boundaries, since that would fault if we didn't allocate the previous page at the same time. -- Eric Blake eblake(a)redhat.com +1-919-301-3266 Libvirt virtualization library http://libvirt.org

Hello, On Thursday 17 November 2011 18:39:15 Eric Blake wrote: > Is any of this worth keeping on the public libvir-list? Not much but to be careful when you upgrade any part of libvirt, qemu(-kvm) or it's (external*) dependencies like etherboot/iPXE, vgabios and seabios, because it can invalidate your snapshots and saved state. (*): As Debian does for DFSG-compliance, since it replaces the seabios / vgabios / pxe-bios as shipped with qemu by a version compiled from (different) sources.
