Xensource v4 new features

quick look at the features:

New features in XenEnterprise v4 include:

  • XenMotion and Server Resource Pools:
    • Combines multiple hosts into a powerful, scalable, and dynamically manageable pool of virtual resources and leverage XenMotion to enable live migration of running virtual machines between hosts to achieve resilient, optimal resource utilization for virtual infrastructure. Automated host configuration means no per-host configuration in a resource pool, dramatically simplifying pool management. Users can simply drop virtual machines on a resource pool and the pool assigns the right resources.
  • 64-bit Hypervisor for Real-World Applications
    • Scales XenEnterprise with increasing memory density and CPU core counts, with support for up to 128GB of physical memory, and with per guest VM limits of 32GB. The new release also supports up to 8-way SMP per guest, and leverages ACPI to support dynamic hot-plugging of CPU, network and storage into running virtual machines. The powerful hypervisor feature-set allows XenEnterprise v4 to support a higher density of virtual machines per host, with increased ROI and consolidation payback.
  • XenCenter: Resilient, Integrated Virtual Infrastructure Management
    • Manages virtual infrastructure for the entire XenSource product family, offering the first enterprise virtualization management solution without a single point of failure. Management state is replicated across all hosts in a resource pool, enabling any host to assume the role of pool leader on demand, and dramatically enhancing resiliency and scalability of virtual infrastructure management. XenCenter is included as part of the core XenEnterprise v4 offering at no additional charge.
  • Open Storage Repository API:
    • Offers the industry’s broadest range of direct attached and shared storage for virtual machines including virtual disk images using NAS, iSCSI and SAN based storage infrastructure certified by XenSource through its OEM agreement with Symantec, whose Veritas Storage Foundation product suite will be included as an integrated component of a forthcoming point release of v4.
    • Delivers powerful snapshotting, cloning and thin provisioning for virtual hard disks, leveraging the integrated features of modern storage infrastructure, without requiring a proprietary cluster file system and backup technologies. Via the open Storage Repository API, customers and partners can implement additional storage repository types, integrating storage virtualization and server virtualization into a powerful virtual infrastructure.
    • Supports file-backed virtual hard disks using the Microsoft VHD format, as well as block backed raw virtual disk images.
  • XenAPI: Open APIs and Development Kits for OEMs, ISVs, and Enterprises
    • Offers the same, XML-RPC standards based management API from XenExpress to XenEnterprise. XenSource v4 offers language bindings in C, C# and Java and a powerful CLI with bindings in three popular scripting languages to empower ISV, OEM and channel partners to create a broad-range of customer-needs driven value-added solutions – protecting management investment and fostering a rich open ecosystem of value-added products.

Security: VMware Workstation 6 vulnerability

vulnerable software: VMware Workstation 6.0 for Windows, possible some other VMware products as well type of vulnerability: DoS, potential privilege escalation I found a vulnerability in VMware Workstation 6.0 which allows an unprivileged user in the host OS to crash the system and potentially run arbitrary code with kernel privileges. The issue is in the vmstor-60 driver, which is supposed to mount VMware images within the host OS. When sending the IOCTL code FsSetVoleInformation with subcode FsSetFileInformation with a large buffer and underreporting its size to at max 1024 bytes, it will underrun and potentially execute arbitrary code.

Our frozen chi's and the Workfloor

I left home when I was 20. I had studied Physics(Major) and had no idea what to do next. I took to the seas, I think looking back it was more like a refuge, an asylum. Seeking to get away from all that peer pressure, myself and what not. 1991 June 7, around midnight I arrive in Lagos, Nigeria. Company agent ships me to the nearby hotel to wait for my first “boat”. That's the first time in my life I saw a lot of people , a race totally different from ours. I was warned to be careful, protect my wallet, but they came across as just about any other regular folk. That was my “first encounter”. Funny, since then I have worked with all kinds of nationalities (Japanese, Chinese, Malaysians, Indonesians, Dutch, Scandinavians, Thai, Americans, Spanish, Argentinians,..I can go on and on). What I have learned in all that is that we are all so much alike. But on board a ship it is “ really ” different. Your job is crucial and you must work together. That makes you accept each other realistica...

Whale Fall ----------------- Dress me up in my new threads clasp my greasy palms grease my hair I'm ready for the fall Watch at all the decadence watching the avalanche I'm slipping down losing my buoyancy What's become of us where have we come this far, this close close to the doors I hear them, sublimal chants I'm on the run I race through the human sea I am the king! I'm the slave to my own undoings I'm the jester in my courtyard We jest as we run We're strolling on that thin rope we grope as we rope we're true heros we're the survivors we're the scavengers we're the friends we're the lovers we're the unbred Soon awaiting the fall we're lurking on us we're osedaxing us we're soon going to be done we'll soon be arrested *osedax(bone devourer, newly discovered marine genus) feeds on a fallen(sunken) whale carcass(which is also called a whale fall).
