[libvirt] Question about migration max downtime in domXML
by Jim Fehlig 20 Jan '15

20 Jan '15

Hi All, I've had a few user requests to add migration max downtime to the domain XML. IIRC, this was discussed on the list quite some time ago, but I'm unable to find it in the archives. My recollection is that max downtime is considered a tunable vs config and as such not included in the domXML. But domXML does contain quite a few tunables, so perhaps my memory is incorrect. Does anyone recall the details? I'd be happy to work on this if folks find it acceptable. Regards, Jim

[libvirt] [PATCH] qemu: Propagate storage errors on migration
by Michal Privoznik 20 Jan '15

20 Jan '15

There's one bug that got more visible with my patches that automatically precreate storage on migration. The problem is, if there's not enough disk space on destination, we successfully finish the migration instead of failing. Firstly, we instruct qemu to copy the storage. And as it copies the data, one write() will return -ENOSPC, eventually, to which qemu reacts by emitting BLOCK_JOB_ERROR. The event is successfully ignored by us. Then, since the block job has finished, BLOCK_JOB_COMPLETED event is emitted too. Secondly, we are not checking for the block job completion as we should. Currently, we do the check by issuing 'query-block-jobs' and then looking in the command's output for the job we are interested in. If course, we don't fail if the job is not there, in which case the number of total bytes to be transferred and bytes already transferred, well they equal both to zero. This is actually the line causing the bug as it sees both numbers equal to each other and gives green light to the actual migration. The fix consist of two parts: In the first, code handling BLOCK_JOB_ERROR is added. It's a monitor event and we should have handler for that anyway. In the second part, the code doing drive mirroring is rewritten so it waits for the events instead of querying on the monitor repeatedly.

[libvirt] [PATCH v2] network: Let domains be restricted to local DNS
by Josh Stone 20 Jan '15

20 Jan '15

This adds a new "localOnly" attribute on the domain element of the network xml. With this set to "yes", DNS requests under that domain will only be resolved by libvirt's dnsmasq, never forwarded upstream. This was how it worked before commit f69a6b987d616, and I found that functionality useful. For example, I have my host's NetworkManager dnsmasq configured to forward that domain to libvirt's dnsmasq, so I can easily resolve guest names from outside. But if libvirt's dnsmasq doesn't know a name and forwards it to the host, I'd get an endless forwarding loop. Now I can set localOnly="yes" to prevent the loop.

[libvirt] libvirt 1.2.10 and latest EL6 qemu-kvm
by liedekef＠telenet.be 19 Jan '15

19 Jan '15

Hi all, I had libvirt 1.2.10 running without issues together with the qemu package qemu-kvm-0.12.1.2-2.415.el6_5.14.x86_64.rpm Now, after updating my server, qemu-kvm became version qemu-kvm-0.12.1.2-2.448.el6_6.x86_64 And as a result, when doing 'virsh start' (virsh define worked ok), the following error occured: 2015-01-19 15:05:26.539+0000: 4347: error : qemuMonitorJSONCheckError:379 : internal error: unable to execute QEMU command 'qom-list': The command qom-list has not been The only thing I could do (even downgrading libvirt to 1.2.9 didn't work), was to downgrade qemu-kvm to the older version again ... Any hints on this? Franky

[libvirt] [PATCH] systemd: fix build without dbus
by Daniel P. Berrange 19 Jan '15

19 Jan '15

The virDBusMethodCall method has a DBusError as one of its parameters. If the caller wants to pass a non-NULL value for this, it immediately makes the calling code require DBus at build time. This has led to breakage of non-DBus builds several times. It is desirable that only the virdbus.c file should need WITH_DBUS conditionals, so we must ideally remove the DBusError parameter from the method. We can't simply raise a libvirt error, since the whole point of this parameter is to give the callers a way to check if the error is one they want to ignore, without having the logs polluted with an error message. So, we add a virErrorPtr parameter which the caller can then either ignore or raise using virSetError. Signed-off-by: Daniel P.

[libvirt] [PATCH V3] libxl: Set path to console on domain startup.
by Anthony PERARD 17 Jan '15

17 Jan '15

The path to the pty of a Xen PV console is set only in virDomainOpenConsole. But this is done too late. A call to virDomainGetXMLDesc done before OpenConsole will not have the path to the pty, but a call after OpenConsole will. e.g. of the current issue. Starting a domain with '<console type="pty"/>' Then: virDomainGetXMLDesc(): <devices> <console type='pty'> <target type='xen' port='0'/> </console> </devices> virDomainOpenConsole() virDomainGetXMLDesc(): <devices> <console type='pty' tty='/dev/pts/30'> <source path='/dev/pts/30'/> <target type='xen' port='0'/> </console> </devices> The patch intend to have the TTY path on the first call of GetXMLDesc.

[libvirt] Git repository browsing online?
by Gary R Hook 16 Jan '15

16 Jan '15

Warning: possibly rhetorical or already answered question ahead. Why is the git repository that is located here: http://libvirt.org/git/?p=libvirt-appdev-guide.git;a=summary which is pointed to by this page here: http://www.libvirt.org/downloads.html Only valid up to 13 Aug 2012? If I pull a copy down from the link on the downloads page: git clone git://libvirt.org/libvirt-appdev-guide.git I get what appears to be a current clone. I'm sure I have missed something somewhere, but shouldn't/couldn't the downloads page be up-to-date? Even if only to say, "no online browsing" ? -- Gary R Hook Senior Kernel Engineer NIMBOXX, Inc

[libvirt] [PATCH] Make ZFS storage pool XML tests optional
by Gary R Hook 16 Jan '15

16 Jan '15

From: Gary R Hook <grhookatwork(a)gmail.com> Do not run ZFS tests when ZFS is unsupported in the environment. The recent patch b4af40226d09adeaf9e33a1d6594c4e8ce7f771d adds tests to storagepoolxml2xmltest for the optional ZFS feature. When ZFS is not included in the configuration these tests should not / cannot be run. Modify Makefile.am and the test source file to check for use of the feature and compile in the tests accordingly.

[libvirt] [PATCHv2 0/7] Sharing code for domain and network routes
by Cédric Bosdonnat 16 Jan '15

16 Jan '15

Hi guys, Here are a few patches to have common route definitions for domains and networks. What has changed since v1: * Split into several patches for backportability as suggested by Laine * Moved the virNetworkRouteDef struct definition in the c file to make sure all routes are created with the virNetworkRouteDefCreate (or Parse) function. This way we can get rid of the redundant checks in the format function. * Moved the prefix computing code into a new virNetworkRouteDefGetPrefix function. * Applied and tweaked John's patches. * Fix the virSocketAddrGetIpPrefix 0.0.0.0 special case as suggested by Laine. Cédric Bosdonnat (5): Fix ipv6 regex in RNG schemas to match '::' Move network route definition to networkcommon.rng Move code related to network routes to networkcommon_conf.[ch] Use the network route definitions for domains virSocketAddrGetIpPrefix 0.0.0.0 special case John Ferlan (2): domain_conf: Resolve Coverity RESOURCE_LEAK domain_conf: Check errors from virSocketAddrFormat docs/formatdomain.html.in | 9 +- docs/schemas/basictypes.rng | 2 +- docs/schemas/domaincommon.rng | 29 +- docs/schemas/network.rng | 20 +- docs/schemas/networkcommon.rng | 22 ++ po/POTFILES.in | 1 + src/Makefile.am | 3 +- src/conf/domain_conf.c | 136 ++----- src/conf/domain_conf.h | 14 +- src/conf/network_conf.c | 297 +--------------- src/conf/network_conf.h | 22 +- src/conf/networkcommon_conf.c | 414 ++++++++++++++++++++++ src/conf/networkcommon_conf.h | 72 ++++ src/libvirt_private.syms | 11 + src/lxc/lxc_container.c | 22 +- src/lxc/lxc_native.c | 20 +- src/network/bridge_driver.c | 44 +-- src/util/virsocketaddr.c | 6 + tests/lxcconf2xmldata/lxcconf2xml-physnetwork.xml | 4 +- tests/lxcconf2xmldata/lxcconf2xml-simple.xml | 4 +- tests/lxcxml2xmldata/lxc-hostdev.xml | 4 +- tests/lxcxml2xmldata/lxc-idmap.xml | 4 +- 22 files changed, 633 insertions(+), 527 deletions(-) create mode 100644 src/conf/networkcommon_conf.c create mode 100644 src/conf/networkcommon_conf.h -- 2.1.2

[libvirt] [PATCHv3 0/3] Fix vmdef usage after ExitMonitor
by Ján Tomko 16 Jan '15

16 Jan '15

The patches 1-2, 6-8 from v2 have been pushed already Device removal and device detach are now squashed together. Both attach and detach skip audit when the domain crashed. (Left to be cleaned up by a separate series) Patches checking the return value in all other non-fatal cases were squashed together with the patch adding ATTRIBUTE_RETURN_CHECK. Rebased to master, added qemuProcessUpdateVideoRamSize, and fixed numerous wrong return values and a few missing EndJobs.

[libvirt] [PATCH] ipv6 check for :: address
by Cédric Bosdonnat 16 Jan '15

Hi John, Here is a possible fix for the coverity issue you mentioned. Since ipv6 addresses are too big to be converted to a single integer, I just looped over the array... not sure that is the most elegant way to do it.
