[libvirt] [PATCH go-xml] remove superfluous state & omitempty entries
by Ryan Goodfellow 05 May '17

05 May '17

This commit removes the superfluous state and omit entries from my last commit. It factors the 'state' data member into a DomainFeatureState struct and only uses that struct where necessary e.g. HyperV features as well as a few top level features such as PMU, HAP etc. The HyperV suffix has also been added to features that are specific to HyperV. --- domain.go | 62 +++++++++++++++++++++++++++++----------------------------- domain_test.go | 26 +++++++++++++----------- 2 files changed, 46 insertions(+), 42 deletions(-) diff --git a/domain.go b/domain.go index c9ffaef..b4b2256 100644 --- a/domain.go +++ b/domain.go @@ -372,61 +372,61 @@ type DomainCPU struct { } type DomainFeature struct { +} + +type DomainFeatureState struct { State string `xml:"state,attr,omitempty"` } type DomainFeatureAPIC struct { -

[libvirt] [PATCH go-xml] add support for domain features

[libvirt] [PATCH] mdev: Cleanup code after commits @daf5081b and @2739a983
by Erik Skultety 05 May '17

So, because mingw is somehow OK with dereferencing a pointer within a VIR_DEBUG macro, compared to outside of it to which it complained with a "potential NULL pointer dereference" error (still a false positive), we can make the code a tiny bit cleaner.

[libvirt] [PATCH] virPerfEventIsEnabled: Accept NULL @perf
by Michal Privoznik 04 May '17

04 May '17

After bdcf6e481 there is a crasher in libvirt. The commit assumes that priv->perf is always set. That is not true. For inactive domains, the priv->perf is not allocated as it is set in qemuProcessLaunch(). Now, usually we differentiate between accesses to inactive and active definition and it works just fine. Except for 'domstats'. There priv->perf is accessed without prior check for domain inactivity. While we could check for that, more robust solution is to make virPerfEventIsEnabled() accept NULL. How to reproduce: 1) ensure you have at least one inactive domain 2) virsh domstats Signed-off-by: Michal Privoznik <mprivozn(a)redhat.com> --- src/util/virperf.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/util/virperf.c b/src/util/virperf.c index fa5b6cc..2c832b3 100644 --- a/src/util/virperf.c +++ b/src/util/virperf.c @@ -297,7 +297,7 @@ virPerfEventDisable(virPerfPtr perf, bool virPerfEventIsEnabled(virPerfPtr perf, virPerfEventType type) { - return perf->events[type].enabled; + return perf && perf->events[type].enabled; } int -- 2.10.2

As planned, I tagged RC1 in git and pushed signed tarball and rpms to the usual place: ftp://libvirt.org/libvirt/ Seems to work in my limited testing, https://ci.centos.org/view/libvirt/ seems mostly clean and happy, but please give it some testing ! Assuming things go well, I think I will make RC2 on Tuesday (Monday being closed in most of Europe we should have one day of worktime to test) and that would imply a release on Thursday 3rd, assuming nothing critical is found, thanks in advance for your testing and reports :-) Daniel -- Daniel Veillard | Red Hat Developers Tools http://developer.redhat.com/ veillard(a)redhat.com | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ http://veillard.com/ | virtualization library http://libvirt.org/

[libvirt] Raising limits for our RPC messages
by Michal Privoznik 04 May '17

04 May '17

Dear list, maybe you've seen us raising limit for various parts of RPC messages (for eaxmple: d15b29be, 66bfc7cc61ca0, e914dcfd, etc.). It usually happens when we receive a report that current limits are not enough. Well, we just did: https://bugzilla.redhat.com/show_bug.cgi?id=1440683 The thing is, virConnectGetAllDomainStats() is unable to encode RPC message because there's so much domains & stats to send that the limit is reached. Now, I was thinking how to approach this problem. Yes, we can raise the limits again. But we also have another approach: split data into multiple messages. The current limit for an RPC message is 4MB. Say you have 9MB of data you want to send to the other side. We could construct 3 messages (4 + 4 + 1) and send them to the other side where the data would be reconstructed. At RPC level, we could use @status header file to represent intermediate messages. That is, for the example above messages with the following headers would be constructed: {.len = 4MB, prog, vers, proc, .type = VIR_NET_REPLY, .serial, .status = VIR_NET_CONTINUE} {.len = 4MB, prog, vers, proc, .type = VIR_NET_REPLY, .serial, .status = VIR_NET_CONTINUE} {.len = 1MB, prog, vers, proc, .type = VIR_NET_REPLY, .serial, .status = VIR_NET_OK} (the actual @len accounts for message header too, so the message would be split into <nearly 4MB + nearly 4MB + slightly over 1MB> chunks, but that is not important right now) Just like we have in streams, VIR_NET_CONTINUE tells that there is more data yet to come, VIR_NET_OK could then mark the last packet in the stream. Cool you say, this could work. But not really. The problem with this approach is: a) we just transform problem to a different one (the limit of number of messages data can be split into) b) increased overhead (message header is sent multiple times) c) I don't expect we will ever support cherry-picking of messages (caller picks just the message that contains data they are interested in and discards the rest). So after all, we will effectively have the limit of message size increased to $limit_of_split_messages * $current_limit_of_message_size. Instead of introducing complex code that splits data into messages and reconstructs back, we might as well increase the current limit of message size. Michal

[libvirt] [PATCH 0/2] news: Update for v3.3.0
by Andrea Bolognani 04 May '17

04 May '17

The release notes have been almost completely neglected this cycle, so I've spent some time going through the git log and trying to include what to me looked like relevant changes. Summaries and descriptions are going to be worse that they would be if they were written by the people implementing the changes, but I reckon it's still better than nothing :) Reviews are much appreciated, but if I won't get any feedback I will push this anyway before release just so that v3.3.0 doesn't end up including such sorry excuse for release notes in the final tarball.
