[libvirt] [PATCH] qemuBuildNicDevStr: Add mq=on for multiqueue networking
by Michal Privoznik 22 Aug '13

22 Aug '13

If user requested multiqueue networking, beside multiple /dev/tap and /dev/vhost-net openings, we forgot to pass mq=on onto the -device virtio-net-pci command line. This is advised at: http://www.linux-kvm.org/page/Multiqueue#Enable_MQ_feature --- Notes: Maybe worth backporting to maintainer branches too.

[libvirt] [PATCH] LXC: mount a fresh /run directory for container
by Gao feng 22 Aug '13

22 Aug '13

The unix socket file /run/systemd/private is used to send reboot/shutdown messages. and since this type of unix sockets are not per net namespace , they are global resources. systemctl in container can use this unix socket to send shutdown message to the systemd-shutdownd running on host. finally the host will be poweroff. this problem occurs when container shares the same root directory with host. this patch umount host's /run directory and mount the /run directory of container as tmpfs.

[libvirt] Is it a problem that "a vm has been shutdown, but its pidfile has not been removed"
by Wangyufei (A) 22 Aug '13

22 Aug '13

Hello, when do steps as follows: 1. start a vm 2. restart libvirtd service 3. shutdown the vm I found the pidfile associated with the vm has not been removed. Analyzing related piece of code, I found when libvirtd service restarted, the vm's _virDomainObj structure(named dom here) in libvirtd will be re-established according to the vm's state-file or config-file, but its member of privateData.pidfile will not be reassigned value. By the way, qemudriver is used in my libvirt. So when the vm is shutdown, its pidfile will not be removed, because the member of privateData.pidfile is NULL. My questions are : 1. Do you think it is a problem when a vm has been shutdown, but its pidfile has not been removed ? 2. Do you think it is expected that the member of privateData.pidfile's value missed after libvirtd restart? If it's a bug then I'll submit the patch to fix it. Also list the related piece of code about removing the vm's pidfile in libvirt for your information: if (priv->pidfile && unlink(priv->pidfile) < 0 && errno != ENOENT) VIR_WARN("Failed to remove PID file for %s: %s", vm->def->name, virStrerror(errno, ebuf, sizeof(ebuf))); Best Regards, -WangYufei

[libvirt] [PATCH] Fix URI connect precedence
by Martin Kletzander 22 Aug '13

22 Aug '13

Commit abfff210 changed the order of vshParseArgv() and vshInit() in order to make fix debugging of parameter parsing. However, vshInit() did a vshReconnect() even though ctl->name wasn't set according to the '-c' parameter yet. In order to keep both issues fixed, I've split the vshInit() into vshInitDebug() and vshInit(). One simple memleak of ctl->name is fixed as a part of this patch, since it is related to the issue it's fixing.

[libvirt] [PATCH 0/5] RFC: VMX parsing improvements
by Doug Goldstein 22 Aug '13

22 Aug '13

A user came into #virt the other day and was trying to get libvirtd to work with VMWare Fusion 5, which is basically the Mac OS X version of VMWare Workstation. In helping him out I noticed a few limitations of our VMX parser so I've added support through this patchset. However I came across the fact that we only support 2 types of CD-ROMs instead of the 3 types that VMWare has which leads me to believe we need to extend our XML syntax to define VMWare VMs so I'm asking for feedback and input. CD-ROM types: - cdrom-image = Provides the ISO to the domain - atapi-cdrom = Provides a NEC emulated ATAPI CD-ROM - cdrom-raw = Passthru for a host CD-ROM drive Currently we model 'atapi-cdrom' as (example uses IDE): <disk type='block' device='cdrom'> <source dev='/dev/scd0'/> <target dev='hda' bus='ide'/> <address type='drive' controller='0' bus='0' target='0' unit='0'/> </disk> I was thinking of making that: <disk type='block' device='cdrom'> <driver name='vmware' type='atapi'/> <source dev='/dev/scd0'/> <target dev='hda' bus='ide'/> <address type='drive' controller='0' bus='0' target='0' unit='0'/> </disk> And making 'cdrom-raw' as: <disk type='block' device='cdrom'> <driver name='vmware' type='raw'/> <source dev='/dev/scd0'/> <target dev='hda' bus='ide'/> <address type='drive' controller='0' bus='0' target='0' unit='0'/> </disk> The documentation is a bit ambiguous if I should instead do: <driver name='atapi'/> and <driver name='raw'/> Which is why the request for input. The other reason I'm asking for input is I'm not quite sure what we want to do about CD-ROMs marked as 'auto detect', which is what VMWare Workstation and VMWare Fusion according to their documentation use as the default for 'cdrom-raw' device type. It will either at boot time connect your CD-ROM drive to the VM or dynamically when the user requests it. In this patchset I've modeled it as an opened CD-ROM drive and expect that VMWare will give us a tray closed event or CD-ROM attached event when it gets attached. I unfortunately don't have VMWare and have not used their products in many years so I can't test this myself.

[libvirt] [PATCHv2 0/5] Introduce API to query IP addresses for given domain
by nehaljwani 22 Aug '13

22 Aug '13

This feature has been requested for a very long time. Since qemu guest agent gives us reliable results, now the wait is over. The RFC was first proposed by Michal Privoznik: http://www.mail-archive.com/libvir-list@redhat.com/msg51857.html A patch was submitted, using structs: http://www.mail-archive.com/libvir-list@redhat.com/msg57141.html Another patch was submitted, using XML: http://www.mail-archive.com/libvir-list@redhat.com/msg57829.html Neither of the patches were accepted, probably due to lack of extensibility and usability. Hence, we thought of using virTypedParameters for reporting list of interfaces along with their MAC address and IP addresses. The RFC can be found here: http://www.mail-archive.com/libvir-list@redhat.com/msg79793.html The idea of extensibility was rejected and rendered out of scope of libvirt. Hence, we were back to structs. This API is called virDomainInterfacesAddresses which returns a dynamically allocated array of virDomainInterface struct. The great disadvantage is once this gets released, it's written in stone and we cannot change or add an item into it. The API supports two methods: * Return information (list of all associated interfaces with MAC address and IP addresses) of all of the domain interfaces by default (if no interface name is provided) * Return information for the specified interface (if an interface name is provided) nehaljwani (5): domifaddr: Implement the public API domifaddr: Implement the remote protocol domifaddr: Implement the API for qemu domifaddr: Add virsh support domifaddr: Expose python binding daemon/remote.c | 122 ++++++++++++++++++++++++++++++++ examples/python/Makefile.am | 2 +- examples/python/README | 1 + examples/python/domipaddrs.py | 50 +++++++++++++ include/libvirt/libvirt.h.in | 32 +++++++++ python/generator.py | 1 + python/libvirt-override-api.xml | 8 ++- python/libvirt-override.c | 117 +++++++++++++++++++++++++++++++ src/driver.h | 7 ++ src/libvirt.c | 99 ++++++++++++++++++++++++++ src/libvirt_public.syms | 5 ++ src/qemu/qemu_agent.c | 151 ++++++++++++++++++++++++++++++++++++++++ src/qemu/qemu_agent.h | 4 ++ src/qemu/qemu_driver.c | 56 +++++++++++++++ src/remote/remote_driver.c | 88 +++++++++++++++++++++++ src/remote/remote_protocol.x | 30 +++++++- src/remote_protocol-structs | 24 +++++++ tools/virsh-domain-monitor.c | 102 +++++++++++++++++++++++++++ tools/virsh.pod | 10 +++ 19 files changed, 906 insertions(+), 3 deletions(-) create mode 100755 examples/python/domipaddrs.py -- 1.7.11.7
