Hello, I''m getting many "Error getting mfn" on a xen4.1.3 with dom0 3.4.11 x86_32. I thought it could be related to xen/mmu: Release just the MFN list, not MFN list and part of pagetables. http://git.kernel.org/?p=linux/kernel/git/konrad/xen.git;a=commit;h=785f62314984ea3af9dd830b020289ba2509ae69 (XEN) Freed 212kB init memory.

This fixes various problems that cropped up with the vdso patches. - Patch 1 fixes an information leak to userspace. - Patches 2 and 3 fix the kernel build on gold. - Patches 4 and 5 fix Xen (I hope). - Patch 6 (optional) adds a trace event to vsyscall emulation. It will make it easier to handle performance regression reports :) [1]

I''ve just had my first attempt at getting VGA passthrough to work, and it crashed the machine. I''m trying to understand whether this is a problem with my hardware, configuration or a software problem. I''m running Xen 4.1.2 with Linux 3.1.2 The CPU is an Intel Core i5-650 http://ark.intel.com/products/43546/Intel-Core-i5-650-Processor-%284M-Cache-3_20-GHz%29 The Video

Hi, I''m doing some testing on Ubuntu 12.04 Alpha. All sounds comes out as static on the Dom0 system. (I can PCI passthrough the audio card to a DomU and that works). Native sound works fine.

With the traditional qemu tree fixed to not use PROT_WRITE anymore in the mmap() call for this region, and with the upstream qemu tree not being capable of handling passthrough, yet, there''s no need to treat Dom specially here anymore. This continues to leave unaddressed the case where PV guests map the MSI-X table page(s) before setting up the first MSI-X interrupt (see the original c/s

Hello, Recently many advanced memory mechanisms are introduced into Xen. One problem we found is the conflict between p2m query and setting. For example, backend drivers always map domU’s page to its own space, during the mapping procedure, situations as follow may happen, when mfn is obtained by gfn_to_mfn(), this mfn is likely to be paged out. first case: grant mapping

I found that I''m able to provoke undefined behaviour with 2.6.38 with extent defragmenting + recompression, eg: mkfs.btrfs /dev/sdb mount /dev/sdb /mnt cp -xa / /mnt find /mnt -print0 | xargs -0 btrfs filesystem defragment -vc After a short time, I was seeing what looked like a secondary effect [1]. Reproducing with lock instrumentation reported recursive spinlock acquisition, probably

Hi, Since a week or two I can''t create two of my three WinXP DomU''s anymore, the third one starts just fine.

Hi All, I am not very familiar with xen details. Now I am thinking of building two privilged domain(domain 0 not driver domain) at boot time. The other question is that wether it is possible to create another domain 0 by domain-builder running in domain0? Does it make sense when domain 0 is shut down unexpectedly another domain 0 can run at once. Maybe it is absurd. I am looking forwards
