Congratulations to the whole Xen Cloud Platform team for their release of XCP 1.0 beta. One new addition that’s particularly interesting is the VastSky cluster storage system from VALinux.
Xen Cloud Platform is the open-source project that underlies Citrix XenServer, which makes XCP a great place to experiment with new and interesting technologies before they are supported by XenServer. VastSky is one of those new community collaborations, with the primary contributions coming from Hirokazu Takahashi, Yamamoto Takashi, Tomoe Sugihara and Isaku Yamahata of VA Linux.
VastSky is a distributed, replicated cluster storage system. It’s been integrated into XCP, so that VMs created on XCP can have their virtual disks stored on VastSky with no extra effort. More information can be found in this slide deck and the project’s SourceForge page.
Here are the other headline features in XCP 1.0:
- Scheduled backup of VMs via snapshot/export (VMPR – VM Protection and Recovery)
- Integration with Citrix XenCenter
- Support for local storage caching (to reduce load on shared storage)
- Support for booting from SAN with multipathing
- Support for Ubuntu and Red Hat Enterprise Linux (RHEL) 6 guest operating systems
- Inclusion of Linux kernel 2.6.32
- Inclusion of blktap (“block tap”) userspace toolkit version 2
