[libvirt] [PATCH] build: fix 32-bit build of admin
by Eric Blake 04 May '16

04 May '16

We can't guarantee which 64-bit type will be used in an RPC struct; while %lu worked on 64-bit Linux, that won't always be the type used on all 64-bit platforms; and certainly is not right for 32-bit: admin.c: In function 'adminDispatchClientGetInfo': admin.c:265:25: error: format '%lu' expects argument of type 'long unsigned int', but argument 7 has type 'uint64_t {aka long long unsigned int}' [-Werror=format=] Signed-off-by: Eric Blake <eblake(a)redhat.com> --- Pushing under the build-breaker rule daemon/admin.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/daemon/admin.c b/daemon/admin.c index 3de09ca..dbf49dd 100644 --- a/daemon/admin.c +++ b/daemon/admin.c @@ -262,8 +262,8 @@ adminDispatchClientGetInfo(virNetServerPtr server ATTRIBUTE_UNUSED, if (!(clnt = virNetServerGetClient(srv, args->clnt.id))) { virReportError(VIR_ERR_NO_CLIENT, - _("no client with matching id '%lu' found"), - args->clnt.id); + _("no client with matching id '%llu' found"), + (unsigned long long) args->clnt.id); goto cleanup; } -- 2.5.5

[libvirt] [PATCH] libvirt.spec.in: remove all changelog entries
by Daniel P. Berrange 04 May '16

04 May '16

The %changelog entries in the RPM are just a poor immitation of the release notes, which is not what %changelog section is for. It should be reflecting changes in the RPM packaging, not changes in the application releases. Further, this bogus list of changes has to be manually deleted every time we sync the RPM with Fedora. Remove them, since they serve no useful purpose. Signed-off-by: Daniel P.

[libvirt] [PATCH 0/2] virsh: Properly handle detach-interface --live --config.
by Nitesh Konkar 04 May '16

04 May '16

The virsh attach virsh detach interface command fails when both live and config are set and when the interface gets attached to different pci slots on live and config xml respectively. When we attach an interface with both --live and --config, the first time they get the same PCI slots, but the second time onwards it differs and hence the virsh detach-interface --live --config command fails. This patch makes sure that when both --live --config are set , qemuDomainDetachDeviceFlags is called twice, once with config xml and once with live xml. Steps to see the issue: virsh attach-interface --domain DomainName --type network --source default --mac 52:54:00:4b:76:5f --live --config virsh detach-interface --domain DomainName --type network --mac 52:54:00:4b:76:5f --live --config virsh attach-interface --domain DomainName --type network --source default --mac 52:54:00:4b:76:5f --live --config virsh detach-interface --domain DomainName --type network --mac 52:54:00:4b:76:5f --live --config Nitesh Konkar (2): virsh: Introduce virshDomainDetachInterface function virsh: Pass the correct live/config xml to virshDomainDetachInterface tools/virsh-domain.c | 128 +++++++++++++++++++++++++++++---------------------- 1 file changed, 73 insertions(+), 55 deletions(-) -- 1.8.3.1

[libvirt] [PATCH v2] bhyve: implement domainShutdown
by Roman Bogorodskiy 04 May '16

04 May '16

Bhyve supports ACPI shutdown by issuing SIGTERM signal to the bhyve process. Add the bhyveDomainShutdown() function and virBhyveProcessShutdown() helper function that just sends SIGTERM to VM's bhyve process. If a guest supports ACPI shutdown then process will be terminated and this event will be noticed by the bhyve monitor code that will handle setting proper status and clean up VM's resources. Also, remove usage of virProcessKillPainfully() from domainDestroy. First, it sends SIGTERM to the process that actually triggers ACPI reset and that's not we want to do. Second, we're doing bhyvectl --destroy later and it kills bhyve process, so there's no need to manually kill it. --- Changes from v1: - Sending SIGKILL dropped completely for destroy due to reasons described in the commit message.

[libvirt] [PATCH] admin: Add a check to reject negative argument for number of typed params
by Erik Skultety 04 May '16

04 May '16

Since nparams can be technically negative, it is a good practice throughout our code to check if nparams actually has a non-negative value. The same effect would be achieved by converting our internal typed params serializer argument to 'unsigned' type, but it definitely would not be the path of least resistance.

[libvirt] RFC: migration with temporary external snapshot design considerations
by Nikolay Shirokovskiy 04 May '16

04 May '16

Hi, all. The result of "[RFC] live migration of VMs with internal snapshots" discussion is that it is nice to have ability to migrate images with internal snapshots while keeping intact their internal snaphot structure. Current qemu drive mirror functionality drops this structure and it is possible to workaround the issue with the help of taking extenal snapshot on source and then blockcommiting it back on destination after migration. The technique of creating temporary external snapshot could be useful in other cases too. For example in case of migration with disks on non cache coherent shared filesystem AFAIU. Thus I want to consider (and in case it is reasonable implement too) this functionality aside from migration with internal snapshots task where we have another issue of moving snapshot metadata to destination. The whole topic of design comes from the fact that blockcommit can fail. The fail itself is not a problem as AFAIK commiting active image does not invalidate it and can be restarted later. So the question is to when and how handle it. This can happen on source when we rollback after unsuccessfull migration or on destination as on finish phase in case of blockcommit fail we can't fail the migration anymore. I see two options. 1. Leave this situation to the mgmt. Thus we need to expose the fact of external snapshot in domain config and somehow signal that mgmt need to take care of situation. Well the fact that we expose this technical snapshot to upper level doubts the whole idea of making the workaround in libvirt itself. 2. Have some kind of background task in libvirt that will try to blockcomit with some policy. Well again, we introduce a policy which is considered to reside in mgmt and introduce background task which makes libvirt mgmt-like too. In anyway we will need to take special care while we have uncommited temporary snapshot. For example if we take internal snapshot at this time then it will be in temporary snapshot and be melted away after temporary snapshot is committed. Other block operations are probably are be affected too in this or another way. We can disable such operations for uncommited temporary snapshot. In case of mgmt managment this is job of mgmt and in case of libvirt managment this should be done in libvirt. All that said I guess the first approach is not the way to go as it fails to archive the goal - hide the details from mgmt layer. As to the second one I'd be glad to hear opinions of the community.
