[libvirt] [PATCH] virprocess: Introduce our own setns() wrapper
by Michal Privoznik 15 Sep '14

15 Sep '14

>From time to time weird bugreports occur on the list, e.g [1]. Even though the kernel supports setns syscall, there's an older glibc in the system that misses a wrapper over the syscall. Hence, after the configure phase we think there's no setns support in the system, which is obviously wrong. On the other hand, we can't rely on linux distributions to provide newer glibc soon. Therefore we need to introduce the wrapper on or own. 1: https://www.redhat.com/archives/libvir-list/2014-September/msg00492.html Signed-off-by: Stephan Sachse <ste.sachse(a)gmail.com> Signed-off-by: Michal Privoznik <mprivozn(a)redhat.com> --- The original patch was ACKed already, I've just rebased it to the current master, and moved the wrapper declaration into virprocess.c as we don't need to pollute the header file.

[libvirt] [PATCH] node_device_udev: Try harder to get human readable vendor:product
by Lubomir Rintel 15 Sep '14

15 Sep '14

The manufacurer and product from USB device itself are usually not particularly useful -- they tend to be missing, or ugly (all-uppercase, padded with spaces, etc.).

[libvirt] [PATCH v2 0/5] Introduce new cputune event
by Pavel Hrdina 15 Sep '14

15 Sep '14

This patch series introduce new cputune event to inform management applications about every change of cputune values for running domains. The first patch introduces a new string helper virSnprintf and the second patch cleans up the virDomanDef structure. There is missing documentation for all events so the documentation for this event will be part of the patches to document all events. Changes from v1: - new virSnprintf helper - complete cleanup of virDomainDef structure - cputune event now uses virTypedParameter Pavel Hrdina (5): introduce virSnprintf helper domain_conf: separate structures from virDomainDef event: introduce new event for cputune add an example how to use cputune event cputune_event: queue the event for cputune updates daemon/remote.c | 45 ++++++++++++++++++ examples/object-events/event-test.c | 52 +++++++++++++++++++- include/libvirt/libvirt.h.in | 19 ++++++++ src/conf/domain_conf.h | 94 ++++++++++++++++++++++--------------- src/conf/domain_event.c | 84 +++++++++++++++++++++++++++++++++ src/conf/domain_event.h | 9 ++++ src/libvirt_private.syms | 3 ++ src/qemu/qemu_cgroup.c | 18 ++++++- src/qemu/qemu_driver.c | 73 ++++++++++++++++++++++++++++ src/remote/remote_driver.c | 41 ++++++++++++++++ src/remote/remote_protocol.x | 14 +++++- src/remote_protocol-structs | 9 ++++ src/util/virstring.c | 25 ++++++++++ src/util/virstring.h | 20 ++++++++ tools/virsh-domain.c | 33 +++++++++++++ 15 files changed, 499 insertions(+), 40 deletions(-) -- 1.8.5.5

[libvirt] [PATCH V2 0/2] cpu: Handle only high order 16 bits of PVR for IBM Power processors
by Pradipta Kr. Banerjee 15 Sep '14

15 Sep '14

IBM Power processors encode PVR as CPU family in high order 16 bits and a CPU version in lower 16 bits. Since there is no significant change in behavior between versions, there is no point adding every single CPU version in cpu_map.xml. Qemu for ppc64 already have the necessary changes. V2: - Incorporate Martin comments from V1 - Rewrite the cpu_map.xml for IBM Power processors Pradipta Kr.

[libvirt] Hyervisor Features elements
by bancfc＠openmailbox.org 15 Sep '14

15 Sep '14

Hello. Under Hypevisor Features for Domain elements, I noticed new features being added like <kvm> <hidden state='on'/> </kvm> Probably more will be added later I am guessing. -Is this a performance feature? -Can it also be applied to qemu only machine templates? (I don't use qemu only, but maintain templates for both that's the reason for asking)

[libvirt] Question : Configuring a VM with backing 1G huge pages across 2 NUMA nodes
by Vinod, Chegu 13 Sep '14

13 Sep '14

Hi Michal, 'have a kernel+qemu+libvirt setup with all recent upstream bits on a given host & was trying to configure a VM with backing 1G huge pages...spanning 2 NUMA nodes. The host had 3 1G huge pages on each of the 2 NUMA nodes : # cat /sys/devices/system/node/node0/hugepages/hugepages-1048576kB/nr_hugepages 3 # cat /sys/devices/system/node/node1/hugepages/hugepages-1048576kB/nr_hugepages 3 And I had the following in the /etc/fstab hugetlbfs /hugepages_1G hugetlbfs pagesize=1GB 0 0 I added the following entries in the xml file for the 4G/4vcpu VM <memoryBacking> <hugepages> <page size='1048576' unit='KiB' nodeset='0'/> <page size='1048576' unit='KiB' nodeset='1'/> </hugepages> </memoryBacking> <vcpu placement='static'>4</vcpu> <cputune> <vcpupin vcpu='0' cpuset='0'/> <vcpupin vcpu='1' cpuset='1'/> <vcpupin vcpu='2' cpuset='8'/> <vcpupin vcpu='3' cpuset='9'/> </cputune> .... <numatune> <memory node="strict" nodeset="0-1"/> </numatune> .... <cpu> <numa> <cell id='0' cpus='0-1' memory='2097152'/> <cell id='1' cpus='2-3' memory='2097152'/> </numa> </cpu> The resulting qemu command looked like this : /usr/local/bin/qemu-system-x86_64 -name vm1 -S -machine pc-i440fx-2.2,accel=kvm,usb=off \ -m 4096 -realtime mlock=off -smp 4,sockets=4,cores=1,threads=1 \ -object memory-backend-file,prealloc=yes,mem-path=/hugepages_1G/libvirt/qemu,size=2048M,id=ram-node0,host-nodes=0-1,policy=bind -numa node,nodeid=0,cpus=0-1,memdev=ram-node0 \ -object memory-backend-file,prealloc=yes,mem-path=/hugepages_1G/libvirt/qemu,size=2048M,id=ram-node1,host-nodes=0-1,policy=bind -numa node,nodeid=1,cpus=2-3,memdev=ram-node1 \ .... There were 3 1G pages available on each NUMA node on the host as shown above... and I noticed that the VM got backed by 3 1G pages from node0 and 1 1G page from node1. #cat /sys/devices/system/node/node0/hugepages/hugepages-1048576kB/free_hugepages 0 # cat /sys/devices/system/node/node1/hugepages/hugepages-1048576kB/free_hugepages 2 Not sure if this was expected behavior given the options I specified in the xml file ? If yes...Is there some additional option to specify (in the XML file) such that only a given number of 1Gig huge pages per node are picked to back the VM (i.e. in the above case just 2 1G from each node) ? Thanks! Vinod

[libvirt] [RFC PATCHv2] network: try to eliminate default network conflict during package install
by Laine Stump 12 Sep '14

12 Sep '14

Sometimes libvirt is installed on a host that is already using the network 192.168.122.0/24. If the libvirt-daemon-config-network package is installed, this creates a conflict, since that package has been hard-coded to create a virtual network that also uses 192.168.122.0/24. In the past libvirt has attempted to warn of / remediate this situation by checking for conflicting routes when the network is started, but it turns out that isn't always useful (for example in the case that the *other* interface/network creating the conflict hasn't yet been started at the time libvirtd start its own networks). This patch attempts to catch the problem earlier - at install time. During the %post install script for libvirt-daemon-config-network, we use a case statement to look through the output of "ip route show" for a route that exactly matches 192.168.122.0/24, and if found we search for a similar route that *doesn't* match (e.g. 192.168.123.0/24). When we find an available route, we just replace all occurrences of "122" in the default.xml that is being created with the newly found 192.168 subnet. This could obviously be made more complicated - examine the template defaul.xml to automatically determine the existing network address and mask rather than hard coding it in the specfile, etc, but this scripting is simpler and gets the job done as long as we continue to use 192.168.122.0/24 in the template. (If anyone with mad bash skillz wants to suggest something to do that, by all means please do). This is intended to at least "further reduce" occurrence of the problems detailed in: https://bugzilla.redhat.com/show_bug.cgi?id=811967 --- Difference from V1: fixed some typos in the commit message as pointed out by Eric. Also switched from using comparison loops for route matching, to using a case statement as a low cost replacement for grep (again, as suggested by Eric). Unless there is an objection, I will push this patch later this afternoon so that we can try it out. In the off chance that it causes any disasters, we have plenty of time to revert before the next release :-) libvirt.spec.in | 31 ++++++++++++++++++++++++++++++- 1 file changed, 30 insertions(+), 1 deletion(-) diff --git a/libvirt.spec.in b/libvirt.spec.in index a6a58cf..90da0c2 100644 --- a/libvirt.spec.in +++ b/libvirt.spec.in @@ -1728,8 +1728,37 @@ fi %if %{with_network} %post daemon-config-network if test $1 -eq 1 && test ! -f %{_sysconfdir}/libvirt/qemu/networks/default.xml ; then + # see if the network used by default network creates a conflict, + # and try to resolve it + # NB: 192.168.122.0/24 is used in the default.xml template file; + # do not modify any of those values here without also modifying + # them in the template. + orig_sub=122 + sub=${orig_sub} + nl=' +' + routes="${nl}$(ip route show | cut -d' ' -f1)" + case ${routes} in + *"${nl}192.168.${orig_sub}.0/24${nl}"*) + # there was a match, so we need to look for an unused subnet + for new_sub in $(seq 123 254); do + case ${routes} in + *"${nl}192.168.${new_sub}.0/24${nl}"*) + ;; + *) + sub=$new_sub + break; + ;; + esac + done + ;; + *) + ;; + esac + UUID=`/usr/bin/uuidgen` - sed -e "s,</name>,</name>\n <uuid>$UUID</uuid>," \ + sed -e "s/${orig_sub}/${sub}/g" \ + -e "s,</name>,</name>\n <uuid>$UUID</uuid>," \ < %{_datadir}/libvirt/networks/default.xml \ > %{_sysconfdir}/libvirt/qemu/networks/default.xml ln -s ../default.xml %{_sysconfdir}/libvirt/qemu/networks/autostart/default.xml -- 1.9.3

[libvirt] Inconsistent behavior between x86_64 and ppc64 when creating guests with NUMA node placement
by Michael Turek 12 Sep '14

12 Sep '14

Hello all, I was recently trying out NUMA placement for my guests on both x86_64 and ppc64 machines. When booting a guest on the x86_64 machine, the following specs were valid (obviously, just notable excepts from the xml): <memory unit='KiB'>8388608</memory> <currentMemory unit='KiB'>8388608</currentMemory> <vcpu placement='static'>4</vcpu> ... <cpu> <topology sockets='4' cores='1' threads='1'/> <numa> <cell cpus='0-2' memory='6144'/> <cell cpus='3' memory='2048'/> </numa> </cpu> However, on ppc64 this causes the following error: error: Failed to create domain from sample_guest.xml error: internal error: early end of file from monitor: possible problem: 2014-09-11T18:44:25.502140Z qemu-system-ppc64: total memory for NUMA nodes (8388608) should equal RAM size (200000000) The 200000000 is actually 8192 MB in bytes and hexidecimal. This is apparently just an issue with the error message. The following specs work on ppc64: <cpu> <topology sockets='4' cores='1' threads='1'/> <numa> <cell cpus='0-2' memory='6291456'/> <cell cpus='3' memory='2097152'/> </numa> </cpu> Note that the memory for each cell is 6144*1024 and 2048*1024 respectively. The issue is that the memory size for each NUMA cell should be specified in KiB, not MB (http://libvirt.org/formatdomain.html#resPartition "|memory| specifies the node memory in kibibyte"). In short, it seems that specifying NUMA cell memory in MB works on x86_64 but not on ppc64. Does anyone have any insight to what's causing this, or if I'm misunderstanding something? Any help is appreciated, thank you! Regards, Mike Turek

This patch attempts to catch the problem earlier - at install time. During the %post install for libvirt-daemon-config-network, we look through the output of "ip route show" for a route that exactly matches 192.1 68.122.0/24, and if found we search for a similar route that *doesn't* match (e.g. 192.168.123.0/24). When we find an available route, we just replace all occurences of "122" in the default.xml that is being created with ${new_sub}. This could obviously be made more complicated - automatically determine the existing network address and mask from examining the template default.xml, etc, but this scripting is simpler and gets the job done as long as we continue to use 192.168.122.0/24 in the template.

This is intended to at least "further reduce" the problems detailed in: https://bugzilla.redhat.com/show_bug.cgi?id=811967 I acknowledge that it doesn't help for cases of pre-built cloud images (or live images that are created on real hardware and then run in a virtual machine), but it should at least eliminate the troubles encountered by individuals doing one-off installs (and could be used to stifle complaints for live images, as long as libvirtd was running on the system where the live image compose took place (or the compose was itself done in a virtual machine that had a 192.168.122.0/24 interface address). --- The question here is: "Will this help some people's situation without causing new problems for anyone else?" I wouldn't mind pushing this patch, but also wouldn't mind if it was just the catalyst for discussion that leads to a better solution.

[libvirt] [PATCHv4 0/8] bulk stats: QEMU implementation
by Francesco Romani 12 Sep '14

12 Sep '14

This patchset enhances the QEMU support for the new bulk stats API to include equivalents of these APIs: virDomainBlockInfo virDomainGetInfo - for balloon stats virDomainGetCPUStats virDomainBlockStatsFlags virDomainInterfaceStats virDomainGetVcpusFlags virDomainGetVcpus This subset of API is the one oVirt relies on. Scale/stress test on an oVirt test environment is in progress. The patchset is organized as follows: - the first patch enhances the internal stats gathering API to accomodate the needs of the groups which extract information using QEMU monitor jobs. - the next five patches implement the bulk stats groups, extracting helpers where do refactoring to extract internal helpers every time it is feasible and convenient. - the seventh patch enhances the virsh domstats command with options to use the new bulk stats. - the last patch enhances the block stats group adding the wr_highest_offset information, needed by oVirt for thin provisioned disks. ChangeLog v4: fixes and cleanups - addressed reviewers comments (Peter, Wang Rui). - pushed domain check into group stats functions. This follows the strategy to gather and report as much data as possible, silently skipping errors along the way. - moved the block allocation patch to the end of the series. v3: more polishing and fixes after first review - addressed Eric's comments. - squashed patches which extracts helpers with patches which use them. - changed gathering strategy: now code tries to reap as much information as possible instead to give up and bail out with error. Only critical errors cause the bulk stats to fail. - moved away from the transfer semantics. I find it error-prone and not flexible enough, I'd like to avoid as much as possible. - rearranged helpers to have one single QEMU query job with many monitor jobs nested inside. - fixed docs. - implemented missing virsh domstats bits. in v2: polishing and optimizations. - incorporated feedback from Li Wei (thanks). - added documentation. - optimized block group to gather all the information with just one call to QEMU monitor. - stripped to bare bones merged the 'block info' group into the 'block' group - oVirt actually needs just one stat from there. - reorganized the keys to be more consistent and shorter.

12 Sep '14

There are two repeats from the last series (1 & 2). For patch 1, I went with my suggestion - I'm open to others For patch 2, Coverity was complaining more about the way nparams would be overwritten - fix that by adding a new variable New patches 3 & 4 -> eblake helped out with these - especially the mgetgroups oddity 5 -> Fallout from fixing 4 6 -> virTimeFieldsThen() and the "offset = 0". I'd be OK with deleting the code, but it just feels like someone had it on a todo list to come back to some day 7 & 8 -> Fairly straightforward 9 -> This was an interesting case - it seems from what was being done that I have the right "answer". I did go all the way back to the initial submission of the code and it did the same thing, except it was using an unsigned long instead of int and well thus wouldn't ever hit the condition since we're grabbing the big endian int value This gets me down to 5 issues John Ferlan (9): remote_driver: Resolve Coverity RESOURCE_LEAK virsh: Resolve Coverity NEGATIVE_RETURNS daemon: Resolve Coverity RESOURCE_LEAK virutil: Resolve Coverity RESOURCE_LEAK virfile: Resolve Coverity RESOURCE_LEAK virtime: Resolve Coverity DEADCODE qemu: Resolve Coverity FORWARD_NULL libxl: Resolve Coverity CHECKED_RETURN virstoragefile: Resolve Coverity DEADCODE daemon/libvirtd.c | 8 ++++---- src/libxl/libxl_driver.c | 3 ++- src/qemu/qemu_capabilities.c | 2 +- src/remote/remote_driver.c | 20 +++++++++++++++++++- src/util/virfile.c | 7 +++++-- src/util/virstoragefile.c | 2 +- src/util/virtime.c | 2 ++ src/util/virutil.c | 1 + tools/virsh-domain.c | 7 ++++--- 9 files changed, 39 insertions(+), 13 deletions(-) -- 1.9.3

[libvirt] [PATCHv3 0/8] bulk stats: QEMU implementation
by Francesco Romani 12 Sep '14

12 Sep '14

This patchset enhances the QEMU support for the new bulk stats API to include equivalents of these APIs: virDomainBlockInfo virDomainGetInfo - for balloon stats virDomainGetCPUStats virDomainBlockStatsFlags virDomainInterfaceStats virDomainGetVcpusFlags virDomainGetVcpus This subset of API is the one oVirt relies on. Scale/stress test on an oVirt test environment is in progress. changes in v3: more polishing and fixes after first review - addressed Eric's comments. - squashed patches which extracts helpers with patches which use them. - changed gathering strategy: now code tries to reap as much information as possible instead to give up and bail out with error. Only critical errors cause the bulk stats to fail. - moved away from the transfer semantics. I find it error-prone and not flexible enough, I'd like to avoid as much as possible. - rearranged helpers to have one single QEMU query job with many monitor jobs nested inside. - fixed docs. - implemented missing virsh domstats bits. changes in v2: polishing and optimizations. - incorporated feedback from Li Wei (thanks). - added documentation. - optimized block group to gather all the information with just one call to QEMU monitor. - stripped to bare bones merged the 'block info' group into the 'block' group - oVirt actually needs just one stat from there. - reorganized the keys to be more consistent and shorter. The patchset is organized as follows: - the first patch enhance the internal stats gathering API to accomodate the needs of the groups which extract information using QEMU monitor jobs. - the next 6 patches implement the bulk stats groups, extracting helpers where do refactoring to extract internal helpers every time it is feasible and convenient. - the last patch enhance the virsh domstats command with options to use the new bulk stats. *** BLURB HERE *** Francesco Romani (8): qemu: bulk stats: extend internal collection API qemu: bulk stats: implement CPU stats group qemu: bulk stats: implement balloon group qemu: bulk stats: implement VCPU group qemu: bulk stats: implement interface group qemu: bulk stats: implement block group qemu: bulk stats: add block allocation information virsh: add options to query bulk stats group include/libvirt/libvirt.h.in | 5 + src/libvirt.c | 61 +++++ src/qemu/qemu_driver.c | 577 +++++++++++++++++++++++++++++++++++++------ src/qemu/qemu_monitor.c | 22 ++ src/qemu/qemu_monitor.h | 21 ++ src/qemu/qemu_monitor_json.c | 211 +++++++++++----- src/qemu/qemu_monitor_json.h | 4 + src/qemu/qemu_monitor_text.c | 13 + src/qemu/qemu_monitor_text.h | 4 + tools/virsh-domain-monitor.c | 35 +++ tools/virsh.pod | 4 +- 11 files changed, 823 insertions(+), 134 deletions(-) -- 1.9.3

[libvirt] libvirt-python: memory leak after GetXMLDesc?
by Junichi Nomura 12 Sep '14

12 Sep '14

Hello, I've observed memory leak in long-running python program and suspects a bug in libvirt-python. libvirt-python contains auto-generated code like this: libvirt_virDomainGetXMLDesc(...) { ... LIBVIRT_BEGIN_ALLOW_THREADS; c_retval = virDomainGetXMLDesc(domain, flags); LIBVIRT_END_ALLOW_THREADS; py_retval = libvirt_charPtrWrap((char *) c_retval); return py_retval; } virDomainGetXMLDesc() expects the caller to free c_retval. Though it used to be freed in libvirt_charPtrWrap(), commit bb3301ba ("Don't free passed in args in libvirt_charPtrWrap / libvirt_charPtrSizeWrap") has moved the responsibility to the outside. So, it seems either GetXMLDesc should not depend on auto-generation or the generator should be fixed. Any comments? -- Jun'ichi Nomura, NEC Corporation

[libvirt] QEMU migration with non-shared storage
by Michael Chapman 12 Sep '14

12 Sep '14

Hello, I am trying to understand libvirt's logic for checking whether migration of a VM is safe, and how it determines which disks should be mirrored by QEMU. My particular use case involves VMs that may have disks backed onto LVM or onto Ceph RBD, or both. As far as I can tell, the qemuMigrationIsSafe check is there to ensure that all disks are readonly, or have cache=none, or their backends can guarantee cache coherence. As far as I can tell, however, QEMU flushes *all* block devices when it pauses a VM's CPUs (just before the final part of migration, for instance), so I'm wondering why this check is needed. Is there any possible situation for the source VM to be paused, for its block devices to be flushed, and yet the destination VM can't see all completed writes? Why is RBD is handled specially in this function? The current logic is that an RBD-backed disk is safe to be migrated even if it's got caching enabled, but I'm not sure how RBD is different from other backends in this regard. If VIR_MIGRATE_NON_SHARED_DISK or _INC is specified, should these safety checks be relaxed? It seems to me that if any non-shared disk is going to be *explicitly* copied from the source to the destination VM, then cache coherence in the backend is irrelevant. At the moment, the set of non-shared block devices copied by VIR_MIGRATE_NON_SHARED_* differs depending on whether NBD is being used in the migration: - If NBD can't be used (e.g. with a tunnelled migration), then QEMU will copy *all* non-readonly block devices; - If NBD is being used, then QEMU will only mirror "shareable", "readonly" or "sourceless" disks. A problem arises with RBD disks that have caching enabled. According to qemuMigrationIsSafe, these disks are "safe" to be migrated. However in either the NBD or the non-NBD case, the RBD disk will be copied. This is clearly not desirable. If RBD is a special case in qemuMigrationIsSafe, does it also need to be a special case when configuring the NBD server? Or, if an NBD server is not going to be used, should the migration be considered "unsafe" if an RBD disk is present? I'd very much appreciate some help in understanding all of this. At the moment, I think my only option is to run RBD without caching at all. However, not only does that result in very poor performance, it also doesn't seem to match the qemuMigrationIsSafe check. Regards, Michael
