We have found a critical problem with the XEN 3.1 release (for those who are running 15-20 VMs on a single server). We are using the official XEN 3.1 release on a rackable server (Dual-Core AMD Opteron, 8GB RAM). The problem we are seeing is that intermittently vifs fail to work properly in VMs after we create around 15-17 VMs on our server (all running at the same time, created one by

Hi Xiph.org Team. We are using opusfile library <https://github.com/xiph/opusfile> for streaming *.opus* audio in our projects. But now we have a problem with building opusfile library for android with *ndk-build*. In particular, with arm64-v8a platform: Google removed <sys/timeb.h> from android. And now building opusfile with nkd-build crashes with error "fatal error:

This patch implements persistent grants for the xen-blk{front,back} mechanism. The effect of this change is to reduce the number of unmap operations performed, since they cause a (costly) TLB shootdown. This allows the I/O performance to scale better when a large number of VMs are performing I/O. Previously, the blkfront driver was supplied a bvec[] from the request queue. This was granted to
