Hi all, when running Windows 2008 SBS on Xen 4.0.0, it disappears after some time (longest time I had it running was 20 minutes). In /var/log/xen/qemu-dm-win1.log I find: xc_map_foreign_batch: mmap failed: Cannot allocate memory xc_map_foreign_bulk error 12 Anyone any idea how to troubleshoot this? The Hypervisor has 16 GB of RAM, currently 2 GB are allocated to Dom0. This specific DomU has 8 GB. thx, B. _______________________________________________ Xen-users mailing list Xen-us...

I built a couple new servers on SLES11 because I needed to use USB. Since SLES11 has xen 3.4 packages that seemed like the way to go. I''m questioning the stability of the two new servers compared to my SLES10SP2 servers. I''m also questioning the performance of Windows domUs. On Thanksgiving day one of my SLES11 servers running 7-8 domUs crashed and restarted three times. Being

Hi, all I''m reading the code of QEMU''s virtio infrastructure (hw/virtio.c) and Linux''s virtio driver (virtio_blk.c, virtio_net.c). Virtio drivers utilize scatter gather infrastructure in the Linux kernel. It stores the physical addresses in scatter list. In Xen''s hvm case, QEMU can access guest address space with cpu_physical_memory_map. However, in

The following dump-core patches changes its format into ELF, adds PFN-GMFN table, HVM support, and adds experimental IA64 support. - ELF format Program header and note section are adopted. - HVM domain support To know the memory area to dump, XENMEM_set_memory_map is added. XENMEM_memory_map hypercall is for current domain, so new one is created. and hvm domain builder tell xen its

The following series of 10 patches is a merge of the xenfb and xenconsoled functionality into the qemu-dm code. The general approach taken is to have qemu-dm provide two machine types - one for xen paravirt, the other for fullyvirt. For compatability the later is the default. The goals overall are to kill LibVNCServer, remove alot of code duplication and/or parallel impls of the same concepts, and
