We has studied on virtualization for years. And we want to share some interesting information on virtualization nowadays. And we also want to have communicate with others who are also interesting in virtualization. The following article is a summary from the Xen-ARM's website and related public documents.
Section 1: Brief introduction to Xen-ARM
Xen-ARM is a hypervisor which is based on ARM architecture. It means that you can run different operating system at the same time when you are using hypervisor. In the category of hypervisor, Xen-ARM is categorized as Type-1 hypervisor[1] . Besides, it's necessary to patch guest OS when you want to use it running on Xen-ARM.
i.e. Xen-ARM is using para-virtualization.
Xen-ARM is based on Xen[2] which is a hypervisor running on x86-platform. Most of developers of Xen-ARM are come from Samsung instead of XenSource which is main maintainer of Xen.
In the early stage of developing time of Xen-ARM, they had only supported FreeScale develop board. However, Xen-ARM has support several develop boards, such as XScale PXA310, Versatile, Realview-PB, Cortex-A9, etc. Meanwhile, Xen-ARM also supports Goldfish which is a QEMU emulator patched for Android. Otherwise, in software part, Xen-ARM had only supported for Linux 2.6.11 as guest OS in the early stage of developing time of Xen-ARM. But, Xen-ARM has supported for Linux 2.6.11, 2.6.18, 2.6.21, 2.6.24, 2.6.27 as guest OS nowadays.
