Hi, on IA64 flushing the whole TLB is very expensive: this is a cpu tlb flush and clearing 16MB of memory (virtual tlb). However, flushing an address range is rather cheap. Flushing an address range on every processors is also cheap (no IPI). Unfortunatly Xen common code flushes the whole TLB after unmapping grant reference. Currently, this is not done on IA64 because domain_dirty_cpumask

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
