[libvirt] [PATCH 0/5] Make sure internal blkiotune values are in sync
by Martin Kletzander 19 Aug '15

19 Aug '15

We were blindly setting blkiotune values for devices, but kernel can throw some of them away. This series reworks the logic the same wayother tuning values are updated. That is, after the value gets set, it is read back again to make sure internal structures are in sync and we can return the values from them. Little example should clear up everything.

[libvirt] [PATCH 0/3] Some minor IOThread API adjustments/checks
by John Ferlan 18 Aug '15

18 Aug '15

As a result of the review of a related issue for virDomainAddIOThread it was noted that it's only our implementation for qemu that doesn't want an iothread_id == 0, see: http://www.redhat.com/archives/libvir-list/2015-August/msg00310.html Continued IRC chats with the submittor of that patch discovered some inconsistencies which are dealt with in this patch series... Patch 1 - Remove the iothread_id arg check in virDomainPinIOThread. Since 0 was allowed by the API anyway and left up to the hypervisor. The argument is unsigned - so in reality all that was being checked was 0 - other similar callers work on 'int' values not 'unsigned int'. Patch 2 - Adjust the description in virDomainAddIOThread to remove the "positive non-zero value" and then rework the text to be clearer that it's up to the hypervisor to decide what values are legal and how to handle possible duplication. Patch 3 - Add check in qemu_driver Add/Del IOThread API for the invalid 0 value for iothread_id NOTE: It's not necessary to add a specific illegal argument check for iothread_id = 0 in qemuDomainPinIOThread since both the live and config paths will first search for the iothread_id value and fail if not found in the iothreadid list. I'm not opposed to adding a specific error message if so desired...

[libvirt] [PATCH] qemuDomainRename: Report error if adding domain to domainObj list fails
by Michal Privoznik 18 Aug '15

18 Aug '15

[libvirt] [PATCH 0/7] qemu: Make it possible to run domains with dirrefent seclabels
by Martin Kletzander 14 Aug '15

14 Aug '15

We offer setting seclabel for the whole domain, but we never fixed the fact that the domain will not be able to even create its monitor socket because the directory is owned by the default preconfigured user and group. Moreover the selinux context can be off as well. So this patch series fixes few preliminary problems and then changes autogenerating so that it creates path per-domain. That way we can start do mains with any seclabels we want without that annoying error message (or similar ones, depends on your configuration): error: Failed to start domain dummy error: internal error: process exited while connecting to monitor: 2015-08-13T15:26:01.474941Z qemu-system-x86_64: -chardev socket,id=charmonitor,path=/var/lib/libvirt/qemu/dummy.monitor,server,nowait: Failed to unlink socket /var/lib/libvirt/qemu/dummy.monitor: Permission denied The idea is mentioned in this thread in which I tried fixing it pretty badly without thinking it through (feel free to read the patch for your amusement): https://www.redhat.com/archives/libvir-list/2015-February/msg01051.htmlA One thing to note here is that tests for patch 5/7 are in a separate patch 6/7 and only minimal. We can also use qemuxml2argvtest to test for the same thing and indeed that is patch 7/7 that I haven't sent. I will send it if anyone wants to have that been done as well, but I believe the qemuxml2argvtest can be left as it currently is because the patch itself has around 350KiB. It's also enough if you just tell me in the review that I should squash it in the previous commit (which I don't suppose anyone will do). Or another idea, I made it available on my github: https://github.com/nertpinx/libvirt.git (branch bz1146886) Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1146886 Martin Kletzander (7):

[libvirt] [PATCH] Inherit namespace feature 2
by ik.nitk 14 Aug '15

14 Aug '15

This patch adds feature for lxc containers to inherit namespaces. This is very similar to what lxc-tools or docker provides. Look for "man lxc-start" and you will find that you can pass command args as [ --share-[net|ipc|uts] name|pid ]. Or check out docker networking option in which you can give --net=container:NAME_or_ID as an option for sharing namespace. >From this patch you can add extra libvirt option to share namespace in following way. <lxc:namespace> <lxc:sharenet type='netns' value='red'/> <lxc:shareipc type='pid' value='12345'/> <lxc:shareuts type='name' value='container1'/> </lxc:namespace> The netns option is specific to sharenet. It can be used to inherit from existing network namespace.w --- docs/drvlxc.html.in | 21 +++++ docs/schemas/domaincommon.rng | 42 +++++++++ src/Makefile.am | 2 +- src/lxc/lxc_conf.c | 2 +- src/lxc/lxc_conf.h | 15 ++++ src/lxc/lxc_container.c | 145 ++++++++++++++++++++++++++++-- src/lxc/lxc_container.h | 1 + src/lxc/lxc_controller.c | 42 ++++++++- src/lxc/lxc_domain.c | 164 +++++++++++++++++++++++++++++++++- src/lxc/lxc_domain.h | 1 + src/lxc/lxc_process.c | 111 +++++++++++++++++++++++ tests/lxcxml2xmldata/lxc-sharenet.xml | 33 +++++++ tests/lxcxml2xmltest.c | 1 + 13 files changed, 570 insertions(+), 10 deletions(-) create mode 100644 tests/lxcxml2xmldata/lxc-sharenet.xml diff --git a/docs/drvlxc.html.in b/docs/drvlxc.html.in index a094bd9..d6c57c4 100644 --- a/docs/drvlxc.html.in +++ b/docs/drvlxc.html.in @@ -590,6 +590,27 @@ Note that allowing capabilities that are normally dropped by default can serious affect the security of the container and the host. </p> +<h2><a name="share">Inherit namespaces</a></h2> + +<p> +Libvirt allows you to inherit the namespace from container/process just like lxc tools +or docker provides to share the network namespace.

[libvirt] [PATCH v4 0/5] domainRename API implementation
by Tomas Meszaros 14 Aug '15

14 Aug '15

This is an effort to implement domain rename API. Presented patch series consists of the following: virDomainRename API implementation for qemu, implementation of the virsh command domrename and the additional support code. The idea behind this endeavor is to provide convenient and safe way to rename a domain. Instead of the: virsh dumpxml domain > domain.xml (change domain name in domain.xml) virsh undefine domain virsh define domain.xml user can simply type: virsh domrename foo bar or call virDomainRename() API and domain "foo" will be renamed to "bar". We currently support only renaming inactive domains without snapshots. Renaming procedure takes care of domain log, config, guest agent path and should be able to recover in case of failure. I've been working on this functionality in collaboration with Michal Privoznik who is my mentor during the GSoC 2015. If you have any questions, ideas or criticism feel free to join the discussion. v2: - removed guest agent path rename code - removed rename permission - added code for emitting undefined+renamed event for the old domain v3: - removed domain rename permission - fixed virDomainRename doc comment - added @flags parameter to the virDomainRename API v4: - removed ATTRIBUTE_UNUSED from the @flags parameter - added virCheckFlags() call - added flags to the remote_domain_rename_args Tomas Meszaros (5): Introduce virDomainRename API virsh: Implement "domrename" command domain_conf: Introducde virDomainObjListRenameAddNew() & virDomainObjListRenameRemove() Introduce new VIR_DOMAIN_EVENT_DEFINED_RENAMED event qemu: Implement virDomainRename examples/object-events/event-test.c | 4 + include/libvirt/libvirt-domain.h | 6 ++ src/conf/domain_conf.c | 35 +++++++++ src/conf/domain_conf.h | 5 ++ src/driver-hypervisor.h | 6 ++ src/libvirt-domain.c | 35 +++++++++ src/libvirt_private.syms | 2 + src/libvirt_public.syms | 5 ++ src/qemu/qemu_driver.c | 147 ++++++++++++++++++++++++++++++++++++ src/remote/remote_driver.c | 1 + src/remote/remote_protocol.x | 18 ++++- src/remote_protocol-structs | 9 +++ tools/virsh-domain.c | 63 +++++++++++++++- tools/virsh.pod | 7 ++ 14 files changed, 340 insertions(+), 3 deletions(-) -- 2.1.0

[libvirt] Entering freeze for libvirt-1.2.17
by Daniel Veillard 13 Aug '15

13 Aug '15

Following discussions on Friday, I applied the patches to deactivate the subset of Admin APIs and revert from 1.3.0 to 1.2.17. I then tagged in git and pushed signed tarballs and rpms to the usual place: ftp://libvirt.org/pub/libvirt/ I didn't run my usual tests on that one, my infra is in flux, so even more reasons for people to give it a try :-) I'm likely to make a candidate release 2 on Tuesday and if all goes well we can push 1.2.17 on Thursday, thanks, Daniel -- Daniel Veillard | Open Source and Standards, Red Hat veillard(a)redhat.com | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ http://veillard.com/ | virtualization library http://libvirt.org/

[libvirt] [patch] Add support for OVMF in virt-aa-helper [Was: [apparmor] virt-aa-helper: does not support OVMF?]
by intrigeri＠debian.org 13 Aug '15

13 Aug '15

Hi, [please Cc me any reply, I'm not subscribed to libvir-list.] it was reported [1] to Ubuntu that virt-aa-helper blocks access to the OVMF files needed to boot UEFI virtual machines in QEMU. After I've confirmed that on Debian sid, Jamie Strandboge suggested a fix. I've successfully tested in my environment (applied on top of 1.2.18) so I'm forwarding it here.
