[libvirt] [PATCH 0/3] add disk driver metadata_cache_size option
by Nikolay Shirokovskiy 08 Nov '18

08 Nov '18

Hi, all. This is a patch series after offlist agreement on introducing metadata-cache-size option for disks. The options itself is described in 2nd patch of the series. There is a plenty of attempts to add option to set qcow2 metadata cache sizes in past, see [1] [2] to name recent that has comments I tried to address or has work I reused to some extent. I would like to address Peter's comment in [1] that this option is image's option rather then disk's here. While this makes sense if we set specific cache value that covers disk only partially, here when we have maximum policy that covers whole disk it makes sense to set same value for all images. The setted value is only upper limit on cache size and thus cache for every image will grow proportionally to image data size "visible from top" eventually I guess. And these sizes are changing during guest lifetime - thus we need set whole disk limit for every image for 'maxium' effect. On the other hand if we add policies different from 'maximum' it may require per image option. Well I can't imagine name for element for backing chain that will have cache size attribute better then 'driver'). And driver is already used for top image so I leave it this way. KNOWN ISSUES 1. when using -driver to configure disks in command line cache size does not get propagated thru backing chain 2. when making external disk snapshot cache size sneak into backing file filename and thus cache size for backing image became remembered there 3. blockcommit after such snapshot will not work because libvirt is not ready for backing file name is reported as json sometimes Looks like 1 can be addressed in qemu. The reason for behaviour in 2 I do not understand honestly. And 3 will be naturally addessed after blockjobs starts working with blockdev configuration I guess.

[libvirt] [PATCH] virNetworkDefUpdateDNSHost: Require both IP and a hostname to match
by W. Trevor King 08 Nov '18

08 Nov '18

Since fc19a0059 (network: backend functions for updating network dns host/srv/txt, 2012-11-12), the matching logic for various network components has been: 1) for HOST records, it's considered a match if the IP address or any of the hostnames of an existing record matches. 2) for SRV records, it's a match if all of domain+service+protocol+target *which have been specified* are matched. 3) for TXT records, there is only a single field to match - name (value can be the same for multiple records, and isn't considered a search term), so by definition there can be no ambiguous matches. But HOST records can have the same hostname for multiple records (similar to TXT records with the same value). The value that needs to be distinct for HOST records is the IP address. This commit updates the matching logic to only consider the IP address. Compared to the previous HOST logic: 1. You can now delete entries from an existing network like: <dns> <host ip="192.168.1.1"> <hostname>example</hostname> </host> <host ip="192.168.1.2"> <hostname>example</hostname> </host> </dns> with input like: <host ip="192.168.1.1"> </host> or: <host ip="192.168.1.1"> <hostname>example</hostname> </host> Previously, only the former would work (the latter used to raise "multiple matching DNS HOST records were found in network"). 2. You can no longer remove entries by hostname alone. Previously, you may have been able to remove an entry from an existing network like: <dns> <host ip="192.168.1.1"> <hostname>example-1</hostname> </host> <host ip="192.168.1.2"> <hostname>example-2</hostname> </host> </dns> with input like: <host name="example"> <hostname>example-1</hostname> </host> using the 'name' property to get through the partialOkay check in virNetworkDHCPHostDefParseXML. Now that input will raise "Missing IP address in network '%s' DNS HOST record". 3. You can now add multiple entries with a common hostname (as long as they have distinct IP addresses). Previously, adding: <host ip="192.168.1.1"> <hostname>example</hostname> </host> to an existing: <host ip="192.168.1.2"> <hostname>example</hostname> </host> would have raised "there is already at least one DNS HOST record with a matching field in network". --- I'm actually not clear on whether the 'ip' attribute is required to be unique or not. If not, maybe the logic should be: * Deletes with just an IP remove all <host> entries that match that IP. * Deletes with just a hostname remove all <hostname> entries that match that hostname. * Deletes with an IP and a hostname remove matching <hostname> entries from <host> entries which match the IP. * If <hostname> removal completely empties a <host>, the <host> is also removed.

[libvirt] Parsing of memory.stat in libvirt
by Peter.Chubb＠data61.csiro.au 08 Nov '18

08 Nov '18

Hi Folks, libvirt currently spams the logs with error : virCgroupGetMemoryStat:2490 : internal error: Cannot parse 'memory.stat' cgroup file whenever someone does ps in a container. This is because the parser for memory/stat is incorrect: the `line' variable is never updated, so each time through the loop, the same start-of-line is compared for the token; and as all spaces are eventually replaced with NUL the error exit is taken instead of ending the loop properly. Here is a strawman patch to fix the problem. Please note, I'm not subscribed to this list; I reported the bug as https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=913023 and was asked to send the patch upstream. src/util/vircgroup.c | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) --- libvirt.orig/src/util/vircgroup.c +++ libvirt/src/util/vircgroup.c @@ -2477,7 +2477,7 @@ virCgroupGetMemoryStat(virCgroupPtr grou line = stat; - while (line) { + while (*line) { char *newLine = strchr(line, '\n'); char *valueStr = strchr(line, ' '); unsigned long long value; @@ -2507,6 +2507,11 @@ virCgroupGetMemoryStat(virCgroupPtr grou inactiveFileVal = value >> 10; else if (STREQ(line, "unevictable")) unevictableVal = value >> 10; + + if (newLine) + line = newLine + 1; + else + break; } *cache = cacheVal; -- Dr Peter Chubb Tel: +61 2 9490 5852 http://ts.data61.csiro.au/ Trustworthy Systems Group Data61 (formerly NICTA)

[libvirt] [PATCH] qemu: Don't ignore resume events
by Jiri Denemark 07 Nov '18

07 Nov '18

Since commit v4.7.0-302-ge6d77a75c4 processing RESUME event is mandatory for updating domain state. But the event handler explicitly ignored this event in some cases. Thus the state would be wrong after a fake reboot or when a domain was rebooted after it crashed. BTW, the code to ignore RESUME event after SHUTDOWN didn't make sense even before making RESUME event mandatory. Most likely it was there as a result of careless copy&paste from qemuProcessHandleStop. https://bugzilla.redhat.com/show_bug.cgi?id=1612943 Signed-off-by: Jiri Denemark <jdenemar(a)redhat.com> --- src/qemu/qemu_process.c | 8 +------- 1 file changed, 1 insertion(+), 7 deletions(-) diff --git a/src/qemu/qemu_process.c b/src/qemu/qemu_process.c index c698c3b29c..59ca7cd333 100644 --- a/src/qemu/qemu_process.c +++ b/src/qemu/qemu_process.c @@ -719,12 +719,7 @@ qemuProcessHandleResume(qemuMonitorPtr mon ATTRIBUTE_UNUSED, priv->runningReason = VIR_DOMAIN_RUNNING_UNKNOWN; } - if (virDomainObjGetState(vm, NULL) == VIR_DOMAIN_PAUSED) { - if (priv->gotShutdown) { - VIR_DEBUG("Ignoring RESUME event after SHUTDOWN"); - goto unlock; - } - + if (virDomainObjGetState(vm, NULL) != VIR_DOMAIN_RUNNING) { eventDetail = qemuDomainRunningReasonToResumeEvent(reason); VIR_DEBUG("Transitioned guest %s out of paused into resumed state, " "reason '%s', event detail %d", @@ -742,7 +737,6 @@ qemuProcessHandleResume(qemuMonitorPtr mon ATTRIBUTE_UNUSED, } } - unlock: virObjectUnlock(vm); virObjectEventStateQueue(driver->domainEventState, event); virObjectUnref(cfg); -- 2.19.1

[libvirt] [PATCH] qemu: snapshot: better error for active external readonly disk
by Nikolay Shirokovskiy 07 Nov '18

07 Nov '18

External snapshot of readonly disk of active domain is impossible but error message [1] is cryptic (it's source is qemu). Let's make error message more user friendly. The problem is libvirtd precreates snapshot image with no write permission which is not expected by qemu. [1] current error message error: internal error: unable to execute QEMU command 'transaction': Could not create file: Permission denied Signed-off-by: Nikolay Shirokovskiy <nshirokovskiy(a)virtuozzo.com> --- By the way if domain is not active then snapshot is possible. However top image will have write permissions after snapshot. We can make snapshot work for active domain I guess if we precreate writable snapshot image, but then we end up running readonly disk on writable image. Also making snapshot of readonly disk is not that practical so let's just fix error message for now. src/qemu/qemu_driver.c | 8 ++++++++ 1 file changed, 8 insertions(+) diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index a52e249..e75931e 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -14683,6 +14683,14 @@ qemuDomainSnapshotPrepare(virDomainObjPtr vm, active, reuse) < 0) goto cleanup; + if (dom_disk->src->readonly && active) { + virReportError(VIR_ERR_CONFIG_UNSUPPORTED, + _("external snapshot for readonly disk %s " + "of active domain is not supported"), + disk->name); + goto cleanup; + } + external++; break; -- 1.8.3.1

[libvirt] [PATCH v3 00/20] Incremental Backup API additions
by Eric Blake 07 Nov '18

07 Nov '18

The following is the latest version of my API proposal for incremental backups, and matches the demo I will be presenting as part of my KVM Forum 2018 talk tomorrow afternoon: https://kvmforum2018.sched.com/event/FzuB/facilitating-incremental-backup-e… The patches are also available via https://repo.or.cz/libvirt/ericb.git at the tag backup-v3. The qemu integration is still incomplete (I don't have push mode backups working, only pull mode; and there are still some things to fine-tune as I figure out how to better support external snapshots and block commit/stream), and I still haven't gotten any opinions on whether it is better to have: virDomainSnapshotCreateXML("<domainsnapshot>...") # existing virDomainBackupBegin("<domainbackup>...", "<domaincheckpoint>...") # this series virDomainSnapshotCheckpointCreateXML("<domainsnapshot>...", "<domaincheckpoint>...") # new or to make checkpoint creation part of the snapshot and backup XML, as in: virDomainSnapshotCreateXML("<domainsnapshot><domaincheckpoint>...</domainsnapshot>") # extension of existing virDomainBackupBegin("<domainbackup><domaincheckpoint>...</domainbackup>") # tweak to this series It's also obvious that we don't want to check in the qemu implementation until after Peter's blockdev work has landed AND qemu has gotten rid of the x- prefix in its QMP interactions, although the state of this series SHOULD be sufficient to prove that the proposed interface is at least flexible enough to adapt to whatever qemu tweaks land and whatever other hypervisors may support. Whether to accept the API now (to make backporting qemu support downstream across versions without rebasing to an even later date for the API) is a harder question; Jirka has already expressed distaste at the idea. There are probably still loads of things needing fixing in this version, I already know I did not address all of Peter's review comments on v2. My unit test coverage is not very complete on the XML parsing, and there are definitely some hacks in place to get things to the point of a working demo that need to be polished for robustness. Below is a diff since the v2 posting (patches 1-10 here, for later patches a comparison against the state of my tree at the time I posted v2):
