[libvirt] Release of libvirt-1.0.1
by Daniel Veillard 21 Dec '12

21 Dec '12

So as scheduled, and since we got only a few fixes on top of rc2 I made the release this morning, it is tagged in the git tree and tarball and rpms are available as usual at: ftp://libvirt.org/libvirt/ This is a balanced release with both new features, a lot of improvements and a reasonable amount of bug fixes too, overall a bit more than 350 commit, accumulated since 1.0.0.

[libvirt] [PATCH] S390: Re-enable capability probing for virtio devices.
by Viktor Mihajlovski 21 Dec '12

21 Dec '12

Since we switched to QMP probing, the object types are spelled out explicitly, i.e. virtio-net-pci. This has effectively disabled the capability detection of s390 virtio devices. The trivial fix is to add the s390 virtio types explicitly to qemuCapsObjectProps.

[libvirt] [PATCH] util: fix botched check for new netlink request filters
by Laine Stump 21 Dec '12

21 Dec '12

This is an adjustment to the fix for https://bugzilla.redhat.com/show_bug.cgi?id=889319 to account for two bonehead mistakes I made. commit ac2797cf2af2fd0e64c58a48409a8175d24d6f86 attempted to fix a problem with netlink in newer kernels requiring an extra attribute with a filter flag set in order to receive an IFLA_VFINFO_LIST from netlink. Unfortunately, the #ifdef that protected against compiling it in on systems without the new flag went a bit too far, assuring that the new code would *never* be compiled. The first problem was that, while some IFLA_* enum values are also not, so checking to see if it's #defined is not a valid method of determining whether or not to add the attribute. Fortunately, the flag that is being set (RTEXT_FILTER_VF) *is* #defined, and it is never present if IFLA_EXT_MASK isn't, so it's sufficient to just check for that flag. And to top it off, due to the code not actually compiling when I thought it did, I didn't realize that I'd been given the wrong arglist to nla_put() - you can't just send a const value to nla_put, you have to send it a pointer to memory containing what you want to add to the message, along with the length of that memory. This time I've actually sent the patch over to the other machine that's expriencing the problem, applied it to the branch being used (0.10.2) and verified that it works properly, i.e. it does fix the problem it's supposed to fix. :-/ --- src/util/virnetdev.c | 8 ++++++-- 1 file changed, 6 insertions(+), 2 deletions(-) diff --git a/src/util/virnetdev.c b/src/util/virnetdev.c index e5a0d6d..898e77a 100644 --- a/src/util/virnetdev.c +++ b/src/util/virnetdev.c @@ -1275,13 +1275,17 @@ virNetDevLinkDump(const char *ifname, int ifindex, goto buffer_too_small; } -# if defined(IFLA_EXT_MASK) && defined(RTEXT_FILTER_VF) +# if defined(RTEXT_FILTER_VF) /* if this filter exists in the kernel's netlink implementation, * we need to set it, otherwise the response message will not * contain the IFLA_VFINFO_LIST that we're looking for. */ - if (nla_put(nl_msg, IFLA_EXT_MASK, RTEXT_FILTER_VF) < 0) + { + uint32_t ifla_ext_mask = RTEXT_FILTER_VF; + + if (nla_put(nl_msg, IFLA_EXT_MASK, sizeof(ifla_ext_mask), &ifla_ext_mask) < 0) goto buffer_too_small; + } # endif if (virNetlinkCommand(nl_msg, recvbuf, &recvbuflen, -- 1.7.11.7

[libvirt] [PATCH] blockjob: fix memleak that prevented block pivot
by Eric Blake 21 Dec '12

21 Dec '12

https://bugzilla.redhat.com/show_bug.cgi?id=888426 The code for doing a block-copy was supposed to track the destination file in drive->mirror, but was set up to do all mallocs prior to starting the copy so that OOM wouldn't leave things partially started. However, the wrong variable was being written; later in the code we silently did 'disk->mirror = mirror' which was still NULL, and thus leaking memory and leaving libvirt to think that the mirror job was never started, which prevented a pivot operation after a copy. * src/qemu/qemu_driver.c (qemuDomainBlockCopy): Initialize correct variable. --- src/qemu/qemu_driver.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index 7d8dd21..184f852 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -13429,7 +13429,7 @@ qemuDomainBlockCopy(virDomainPtr dom, const char *path, } if (!format && disk->mirrorFormat > 0) format = virStorageFileFormatTypeToString(disk->mirrorFormat); - if (!(disk->mirror = strdup(dest))) { + if (!(mirror = strdup(dest))) { virReportOOMError(); goto endjob; } -- 1.7.1

[libvirt] vhost-net on ethernet interface type
by Raja Sivaramakrishnan 21 Dec '12

21 Dec '12

Hello, I would like to enable vhost-net on an interface of ethernet type. However, this doesn't work, probably due to the following code in libvirt. if (actualType == VIR_DOMAIN_NET_TYPE_NETWORK || actualType == VIR_DOMAIN_NET_TYPE_BRIDGE || actualType == VIR_DOMAIN_NET_TYPE_DIRECT) { /* Attempt to use vhost-net mode for these types of network device */ Can VIR_DOMAIN_NET_TYPE_ETHERNET also be included in the check above? Or is there some reason to disable vhost-net for this type? Thanks, Raja

[libvirt] [PATCH 0/8] Dump domain's IP addresses
by Michal Privoznik 21 Dec '12

21 Dec '12

It's been a while since I tried get this in. I've reworked the patches, the exposed API, and start new round of reviews. Moreover, during work I've come to point, where extending qemu guest agent seemed wise: http://lists.nongnu.org/archive/html/qemu-devel/2012-12/msg03264.html Therefore I am introducing 'flags' field, which can contain some boolean values we don't have yet, e.g. IFF_UP, IFF_PROMISC, etc. Re: 'dstaddr' field in struct _virDomainInterfaceIPAddress; It's basically a join of: union { char *dstaddr; /* for IFF_POINTOPOINT interface */ char *broadaddr; /* for IFF_BROADCAST interface */ } Since an interface cannot has both flags set (see man 3 getifaddrs) I've joined both into one 'char *dstaddr'. I know it is not mnemonic as the union, so I left it for discussion. I can change it if you want to.

[libvirt] [PATCH v2 0/28] Rename files in src/util to have a 'vir' prefix
by Daniel P. Berrange 21 Dec '12

21 Dec '12

Currently the files in src/util are 50/50 split between those having a 'vir' prefix and those which don't. Finish the job by remaining all remaining files to have a 'vir' prefix too, guaranteeing that they can't clash with system headers[1]. The only case which was not a plain rename, was merging processinfo.{c,h} into the virprocess.{c,h} since the functionality logically belongs together. At the end src/Makefile.am is updated to sort util files alphabetically. Left as further work - make sure all functions in these files also have a 'vir' prefix. eg dnsmasq, ebtables, iptables, usb and pci files are violators in this regard. Also left, much of virutil.c should move into virfile.c Changes in v2: - Rebased to latest GIT - Turned on rename detection to make review easier Daniel [1] Not a theoretical problem - we already hit a clsah on 'usb.h' before forcing us to use 'hostusb.h' and 'memory.h' clashes with a system header but we never noticed so far.
