[libvirt] [PATCH] virsh: fix vcpupin info
by Pavel Hrdina 20 Feb '15

20 Feb '15

The "virDomainGetInfo" will get for running domain only live info and for offline domain only config info. There was no way how to get config info for running domain. We will use "vshCPUCountCollect" instead to get the correct cpu count that we need to pass to "virDomainGetVcpuPinInfo". Also cleanup some unnecessary variables and checks that are done by drivers.

[libvirt] [PATCH] network: allow <pf> together with <interface>/<address> in network status
by Laine Stump 20 Feb '15

20 Feb '15

The function that parses the <forward> subelement of a network used to fail/log an error if the network definition contained both a <pf> element as well as at least one <interface> or <address> element. That check was present because the configuration of a network should have either one <pf>, one or more <interface>, or one or more <address>, but never combinations of multiple kinds. This caused a problem when libvirtd was restarted with a network already active - when a network with a <pf> element is started, the referenced PF (Physical Function of an SRIOV-capable network card) is checked for VFs (Virtual Functions), and the <forward> is filled in with a list of all VFs for that PF either in the form of their PCI addresses (a list of <address>) or their netdev names (a list of <interface>); the <pf> element is not removed though. When libvirtd is restarted, it parses the network status and finds both the original <pf> from the config, as well as the list of either <address> or <interface>, fails the parse, and the network is not added to the active list. This failure is often obscured because the network is marked as autostart so libvirt immediately restarts it. It seems odd to me that <interface> and <address> are stored in the same array rather than keeping two separate arrays, and having separate arrays would have made the check much simpler. However, changing to use two separate arrays would have required changes in more places, potentially creating more conflicts and (more importantly) more possible regressions in the event of a backport, so I chose to keep the existing data structure in order to localize the change. It appears that this problem has been in the code ever since support for <pf> was added (0.9.10), but until commit 34cc3b2f106e296df5e64309620c79d16fd76c85 (first in libvirt 1.2.4) networks with interface pools were not properly marked as active on restart anyway, so there is no point in backporting this patch any further than that. --- src/conf/network_conf.c | 10 +--------- src/network/bridge_driver.c | 35 +++++++++++++++++++++++++++++++++++ 2 files changed, 36 insertions(+), 9 deletions(-) diff --git a/src/conf/network_conf.c b/src/conf/network_conf.c index f947d89..dce3360 100644 --- a/src/conf/network_conf.c +++ b/src/conf/network_conf.c @@ -1,7 +1,7 @@ /* * network_conf.c: network XML handling * - * Copyright (C) 2006-2014 Red Hat, Inc. + * Copyright (C) 2006-2015 Red Hat, Inc. * Copyright (C) 2006-2008 Daniel P.

[libvirt] dmidecode dependency
by Jason Helfman 19 Feb '15

19 Feb '15

Hello All, I was wondering if it may be possible to call sysctl, instead of requiring dmidecode to be installed for getting the uuid of a system? According to the user that filed the bug below, dmidecode needs to be installed to get the uuid, or errors will be printed in logs to get the uuid. https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=196733 I was wondering if sysctl can be called to get this information for FreeBSD? I am not sure if Linux would give similar information, but would think it might. Beyond this, I am not sure if dmidecode is used for other aspects beyond uuid where it is required where sysctl doesn't give the information needed. $ sudo dmidecode |grep -i uuid UUID: 42355DE8-C55C-E487-8E16-509A78EB5EE1 $ sysctl kern.hostuuid kern.hostuuid: 42355de8-c55c-e487-8e16-509a78eb5ee1 Thanks, Jason -- Jason Helfman | FreeBSD Committer jgh(a)FreeBSD.org | http://people.freebsd.org/~jgh | The Power to Serve

[libvirt] [RFC PATCH] Use PAUSED state for domains that are starting up
by Jiri Denemark 19 Feb '15

19 Feb '15

When libvirt is starting a domain, it reports the state as SHUTOFF until it's RUNNING. This is not ideal because domain startup may take a long time (usually because of some configuration issues, firewalls blocking access to network disks, etc.) and domain lists provided by libvirt look awkward. One can see weird shutoff domains with IDs in a list of active domains or even shutoff transient domains. In any case, it looks more like a bug in libvirt than a normal state a domain goes through. I'm not quite sure what the best way to fix this is. In this patch, I tried to use PAUSED state with STARTING_UP reason. Alternatively, we could keep using SHUTOFF state and just set STARTING_UP reason instead of UNKNOWN but it just feels wrong and wouldn't really solve the confusion when looking at virsh list. I made the change to qemu driver only in this RFC patch, I will update all drivers once we agree on the best approach.

[libvirt] [PATCH] virsh-edit: Make force editing usable
by Martin Kletzander 19 Feb '15

19 Feb '15

When editing a domain with 'virsh edit' and failing validation, the usual message pops up: Failed. Try again? [y,n,f,?]: The option 'f' (force) is pretty unusable. It tries to step into the same puddle again and again when it can at least try to force the definition. This patch adds support for relaxing definition in virsh-edit and makes 'virsh edit <domain>' more usable, mainly for testing.

[libvirt] [PATCH v2] Search for schemas and cpu_map.xml in source tree
by Jiri Denemark 19 Feb '15

19 Feb '15

Not all files we want to find using virFileFindResource{,Full} are generated when libvirt is built, some of them (such as RNG schemas) are distributed with sources. The current API was not able to find source files if libvirt was built in VPATH. Both RNG schemas and cpu_map.xml are distributed in source tarball.
