[PATCH] spec: Restart sockets even when libvirtd is inactive

by Jim Fehlig

By default libvirtd will terminate itself after 120 seconds, so it is likely that the daemon will not be running at package upgrade. Try restarting sockets even if the daemon is inactive.

[libvirt PATCH] qemu_migration: Delete vDPA check

by Eugenio Pérez

Currently, the migration code denies migration as long as the VM has a vhost-vDPA device. While it's true that vhost-vDPA devices cannot be migrated at the moment, there are plans to be able to migrate them soon. Libvirt must treat it equal to vhost-kernel devices: Not all of them can be migrated (the ones that do not expose the feature VHOST_F_LOG_ALL cannot be migrated). So checks like this one should work for all vhost devices equally. A more accurate solution is to ask qemu if it has an active migration blocker at that moment. Hoever, that require synchronization to avoid qemu to add one between the query and the actual migration command.

[libvirt PATCH 0/9] [RFC] Dynamic CPU models

by Tim Wiederhake

libvirt and qemu cpu models are out of sync. libvirt cpu models are considered static and never changing, whereas qemu cpu models have changed over time. This leads to problems and confusion for users, as the cpu models they specify may have different features than what they expect. This series introduces two new APIs to enumerate and retrieve cpu models dynamically from the hypervisor at runtime, allowing the user to make use of cpu models from newer hypervisor versions even if libvirt is not aware of them. These two new functions are intended as building blocks onto which higher-level functionality can be build, e.g. the ability to specify a hypervisor cpu model directly in a domain xml. With these two functions alone this has to be done manually for now, i.e. enumerate the available cpu models, retrieve the cpu description and manually insert it into the domain xml accordingly: $ virsh hypervisor-cpu-models --arch x86_64 Name Alias ---------------------------------------------------- max host base qemu64-v1 qemu64 qemu64-v1 qemu32-v1 qemu32 qemu32-v1 phenom-v1 phenom phenom-v1 (...) $ virsh hypervisor-cpu-definition --machine pc --arch x86_64 qemu64 <cpu> <model>qemu64</model> <feature name='cmov'/> <feature name='mmx'/> <feature name='xd'/> <feature name='x-intel-pt-auto-level'/> <feature name='kvm_asyncpf'/> <feature name='kvm-asyncpf'/> <feature name='legacy-cache'/> <feature name='vmware-cpuid-freq'/> <feature name='mce'/> <feature name='mca'/> <feature name='msr'/> <feature name='fxsr'/> <feature name='cpuid-0xb'/> <feature name='kvm_pv_eoi'/> <feature name='pni'/> <feature name='x2apic'/> <feature name='i64'/> <feature name='pae'/> <feature name='pat'/> <feature name='sse'/> <feature name='kvm_nopiodelay'/> <feature name='kvm-nopiodelay'/> <feature name='kvmclock-stable-bit'/> <feature name='hypervisor'/> <feature name='syscall'/> <feature name='x-migrate-smi-count'/> <feature name='full-cpuid-auto-level'/> <feature name='sse3'/> <feature name='sse2'/> <feature name='kvm-pv-eoi'/> <feature name='cx8'/> <feature name='pge'/> <feature name='fill-mtrr-mask'/> <feature name='cx16'/> <feature name='de'/> <feature name='clflush'/> <feature name='tsc'/> <feature name='fpu'/> <feature name='check'/> <feature name='apic'/> <feature name='kvm-steal-time'/> <feature name='kvm_steal_time'/> <feature name='kvmclock'/> <feature name='l3-cache'/> <feature name='nx'/> <feature name='tcg-cpuid'/> <feature name='lm'/> <feature name='pse'/> <feature name='sep'/> <feature name='kvm'/> <feature name='lahf-lm'/> <feature name='lahf_lm'/> <feature name='mtrr'/> <feature name='pse36'/> </cpu> The returned cpu description is currently completely unfiltered, as can be seen by the duplicate entries differing only in "-" vs. "_" usage, inclusion of experimental feature flags and generally, flags that are not recognized by libvirt. One possibility to adress this would be to extend virQEMUCapsCPUFeatureTranslate. Before I continue with this, I would love to hear other people's thoughts, comments and potential use cases.
