[libvirt] [jenkins@libvirt.sigxcpu.org: Build failed in Jenkins: libvirt-check #419]
by Guido Günther 25 Dec '12

25 Dec '12

Hi, it seems one of these commits 5411e7e176dcbb65591cb97ec128b5fd0f365805 473011334ccd93e8efbb67f2561f1d4e54d212ae 392c192240566d9e167d2b5a1022092d8f7e045c broke "make check" as seen on http://honk.sigxcpu.org:8001/job/libvirt-check/417/console output attached. I can't look into this in more right now though. Cheers, -- Guido P.S.: the libvirt-tck check is also currently broken but that's probably a fallout of the above.

[libvirt] libvirt will wait 20 minutes or hang when the network interface down
by Benjamin Wang (gendwang) 24 Dec '12

24 Dec '12

Hi, I find that when the network interface is down. In most scenarios, the libvirt will wait 20 minutes and report the exception. In seldom scenarios, the polling thread will hang even if the network is recovered. The following is the formal description from libcurl website: http://curl.haxx.se/docs/faq.html (Section "4.19 Why doesn't cURL return an error when the network cable is unplugged?") The following is the similar case about thread hand: http://curl.haxx.se/mail/lib-2010-07/0108.html For "wait 20 minutes", although this is the TCP normal mechanism, but if a server manages tons of thousands of devices by libvirt. When 1000 devices are down, This could cause thread leak for a long period. For thread hang, this could cause thread leak forever. I tried to add the following codes in esx_vi.c. It seems that these code can avoid the above issues. Would you give your comments? if (curl->headers == NULL) { virReportError(VIR_ERR_INTERNAL_ERROR, "%s", _("Could not build CURL header list")); return -1; } + curl_easy_setopt(curl->handle, CURLOPT_LOW_SPEED_LIMIT, 10); + curl_easy_setopt(curl->handle, CURLOPT_LOW_SPEED_TIME, 120); curl_easy_setopt(curl->handle, CURLOPT_USERAGENT, "libvirt-esx"); curl_easy_setopt(curl->handle, CURLOPT_HEADER, 0); curl_easy_setopt(curl->handle, CURLOPT_FOLLOWLOCATION, 0); curl_easy_setopt(curl->handle, CURLOPT_SSL_VERIFYPEER, B.R.

[libvirt] [PATCH 0/8] Fix PowerPC CPU driver
by Jiri Denemark 22 Dec '12

22 Dec '12

Current PowerPC driver is too complicated and mostly wrong as it was apparently created from x86 driver and not properly addapted for PowerPC architecture. More details about the issues are described in individual patches. Jiri Denemark (8): cpu: Introduce cpuModelIsAllowed internal API cpu: Make comparing PowerPC CPUs easier to read cpu: Fix PowerPCNodeData cpu: Fix loading PowerPC vendor from cpu_map.xml cpu: Reimplement PowerPCBaseline cpu: Reimplement PowerPCDecode cpu: Remove hardcoded list of PowerPC models cpu: Rename PowerPCUpdate and PowerPCDataFree functions src/cpu/cpu.c | 17 ++ src/cpu/cpu.h | 5 + src/cpu/cpu_generic.c | 19 +-- src/cpu/cpu_map.xml | 12 +- src/cpu/cpu_powerpc.c | 462 +++++++++++++++++--------------------------------- src/cpu/cpu_x86.c | 11 +- 6 files changed, 193 insertions(+), 333 deletions(-) -- 1.8.0.2

[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
