[libvirt] [PATCH v2] maint: use $(SED) instead of sed for syntax-check
by Roman Bogorodskiy 13 May '14

13 May '14

This is actually almost the same patch that I've sent back in January, decided to re-send as much time has passed. Also, now we're not blocked by the gnulib part. I've been using this patch on FreeBSD for quite some time now and had no problems with it. Also, I tested it on Linux and it doesn't seem to cause any regressions.

[libvirt] troubles creating an OVS network with xen, libxl and libvirt.
by Alvin Starr 13 May '14

13 May '14

One more quirk I can create a domain using the lx commands and a slightly modified .conf file. "virsh start kvmtest" returns a failure. I tracked the information passed to vif-openvswitch and it is being called with type_if=tap and it needs to be type_if=vif. Any help would be greatly appreciated once again. -- Alvin Starr || voice: (905)513-7688 Netvel Inc. || Cell: (416)806-0133 alvin(a)netvel.net ||

[libvirt] [PATCH] qemu: Adjust size for qcow2/qed if not on sector boundary (rewrite)
by John Ferlan 12 May '14

12 May '14

A post commit id 'e3d66229' review (and followup): http://www.redhat.com/archives/libvir-list/2014-May/msg00268.html noted some issues with the code, so I have adjusted the code accordingly. The difference between this and the commit prior to the change (commit id 'f3be5f0c') will just be the check for qcow2/qed using a non 512 block aligned size will result in a round up of size. If the size is within the last 512 bytes to ULLONG_MAX, then just set it there rather than erroring out.

[libvirt] [PATCH] util: Fix return type mismatch for nl_recv
by Wangrui (K) 12 May '14

12 May '14

1. As shown in the definition of nl_recv, its return value is of INT type. int nl_recv(struct nl_handle *handle, struct sockaddr_nl *nla, unsigned char **buf, struct ucred **creds) However, in function virNetlinkCommand, it uses an unsigned int param, respbuflen, to receive its return value. Thus, the branch "*respbuflen < 0" is unreachable, negative return values are handled incorrectly. 2. It's said in nl_recv's description that "The caller is responsible for freeing the buffer allocated * in \c *buf if a positive value is returned." which means, we needn't to free it in case it fails. Additionally, nl_recv has a BUG in handling buf: in the error branch, it frees the buf, but didn't set it to NULL. Freeing it outside in the caller function will cause double free. Thus, we set but(resp) to NULL if nl_recv fails.

[libvirt] [VHPC’14] LAST Call for Papers - Deadline in 4 weeks
by VHPC 14 12 May '14

12 May '14

================================================================= CALL FOR PAPERS 9th Workshop on Virtualization in High-Performance Cloud Computing (VHPC '14) held in conjunction with Euro-Par 2014, August 25-29, Porto, Portugal (Springer LNCS) ================================================================= Date: August 26, 2014 Workshop URL: http://vhpc.org Paper Submission Deadline: June 9, 2014 (extended) Confirmed Keynote Speakers: Ron Brightwell, Sandia National Laboratory Hobbes: Using Virtualization to Enable Exascale Applications and Helge Meinhard, CERN CALL FOR PAPERS Virtualization technologies constitute a key enabling factor for flexible resource management in modern data centers, and particularly in cloud environments. Cloud providers need to dynamically manage complex infrastructures in a seamless fashion for varying workloads and hosted applications, independently of the customers deploying software or users submitting highly dynamic and heterogeneous workloads. Thanks to virtualization, we have the ability to manage vast computing and networking resources dynamically and close to the marginal cost of providing the services, which is unprecedented in the history of scientific and commercial computing. Various virtualization technologies contribute to the overall picture in different ways: machine virtualization, with its capability to enable consolidation of multiple under-utilized servers with heterogeneous software and operating systems (OSes), and its capability to live-migrate a fully operating virtual machine (VM) with a very short downtime, enables novel and dynamic ways to manage physical servers; OS-level virtualization, with its capability to isolate multiple user-space environments and to allow for their co-existence within the same OS kernel, promises to provide many of the advantages of machine virtualization with high levels of responsiveness and performance; I/O Virtualization allows physical NICs/HBAs to take traffic from multiple VMs; network virtualization, with its capability to create logical network overlays that are independent of the underlying physical topology and IP addressing, provides the fundamental ground on top of which evolved network services can be realized with an unprecedented level of dynamicity and flexibility; the increasingly adopted paradigm of Software-Defined Networking (SDN) promises to extend this flexibility to the control and data planes of network paths. These technologies have to be inter-mixed and integrated in an intelligent way, to support workloads that are increasingly demanding in terms of absolute performance, responsiveness and interactivity, and have to respect well-specified Service- Level Agreements (SLAs), as needed for industrial-grade provided services. Indeed, among emerging and increasingly interesting application domains for virtualization, we can find big-data application workloads in cloud infrastructures, interactive and real-time multimedia services in the cloud, including real-time big-data streaming platforms such as used in real-time analytics supporting nowadays a plethora of application domains. Distributed cloud infrastructures promise to offer unprecedented responsiveness levels for hosted applications, but that is only possible if the underlying virtualization technologies can overcome most of the latency impairments typical of current virtualized infrastructures (e.g., far worse tail-latency). What is more, in data communications Network Function Virtualization (NFV) is becoming a key technology enabling a shift from supplying hardware-based network functions, to providing them in a software-based and elastic way. In conjunction with (public and private) cloud technologies, NFV may be used for constructing the foundation for cost-effective network functions that can easily and seamlessly adapt to demand, still keeping their major carrier-grade characteristics in terms of QoS and reliability. The Workshop on Virtualization in High-Performance Cloud Computing (VHPC) aims to bring together researchers and industrial practitioners facing the challenges posed by virtualization in order to foster discussion, collaboration, mutual exchange of knowledge and experience, enabling research to ultimately provide novel solutions for virtualized computing systems of tomorrow. The workshop will be one day in length, composed of 20 min paper presentations, each followed by 10 min discussion sections, and lightning talks, limited to 5 minutes. Presentations may be accompanied by interactive demonstrations.
