by KVM Forum 2012 Program Committee 21 Jun '12

21 Jun '12

KVM is an industry leading open source hypervisor that provides an ideal platform for datacenter virtualization, virtual desktop infrastructure, and cloud computing. Once again, it's time to bring together the community of developers and users that define the KVM ecosystem for our annual technical conference. We will discuss the current state of affairs and plan for the future of KVM, its surrounding infrastructure, and management tools. We are also excited to announce the oVirt Workshop will run in parallel with the KVM Forum, bringing in a community focused on enterprise datacenter virtualization management built on KVM. So mark your calendar and join us in advancing KVM. Once again we are colocated with The Linux Foundation's LinuxCon, Based on feedback from last year, this time it's LinuxCon Europe! Conference: November 7 - 9, 2012 Location: Hotel Fira Palace - Barcelona, Spain Details regarding registration and proposal submission are forthcoming. thanks, your KVM Forum 2012 Program Commitee

[libvirt] [PATCH 3/5] S390: Add support for virtio-s390 devices.
by Viktor Mihajlovski 21 Jun '12

21 Jun '12

The s390(x) architecture doesn't feature a PCI bus. For the purpose of supporting virtio devices a virtual bus called virtio-s390 is used. A new address type VIR_DOMAIN_DEVICE_ADDRESS_TYPE_VIRTIO_S390 is used to distinguish the virtio devices on s390 from PCI-based virtio devices.

[libvirt] [PATCH 1/5] S390: Extended qemuDomainAssignAddresses to be callable from everywhere
by Viktor Mihajlovski 21 Jun '12

21 Jun '12

This is in preparation of the enablement of s390 guests with virtio devices. The assignment of device addresses happens in different places, i.e. the qemu driver and process modules as well as in the unit tests in slightly different flavors. Currently, these are PPC spapr-vio and PCI devices, virtio-s390 (not PCI based) will follow. By optionally passing to qemuDomainAssignAddresses the domain object and the capabilities it is now possible to call the function from most of the places (except for hotplug) where address assignment is done.
