This is my current set of updates to Xen for 2.6.24. This is largely a bugfix set, and a couple of them are also relevent to 2.6.23. These are in the pre-x86 merge form; I'll update them once the merge goes into git. Quick overview: - remove some dead code in arch/i386/mm/init.c - clean up some duplicate includes - when sending an IPI, yield the vcpu if the destination doesn't have

Hello, I encountered the following bug when migrating a Linux-2.6.32.54 PV domain on Xen-3.4.3 between different hosts, whose uptime differs by several minutes (3 hosts, each ~5 minutes apart): When migrating from a host with lower uptime to a host with higher uptime, the VM looses it''s network connection for some time and then continues after some minutes (roughly equivalent to the

Hi, I believe I can post this here. I have a domU ( Redhat 6) running in Paravirt mode. When I migrate this domU to another host, looks like the domU is freezing in the other host. When I take it back to original host ,it starts to run normally and this is what can see in dmesg of domU : suspending xenstore... trying to map vcpu_info 0 at ffff88000434b020, mfn b67660, offset 32 cpu 0 using

Dear all, I have running a DOM-0 on debian squeeze with the most recent kernel: Linux 2.6.32-5-xen-amd64 #1 SMP On 30% of all reboots the system hangs and only a reset helps. acpi=off as an additional kernel parameter solves this problem, but the usb keyboard of the installed ip-kvm is not found then. with acpi=off Ican find a lot stuff like: [ 7.098747] uhci_hcd 0000:00:1d.2: UHCI Host

Package: xen-hypervisor-4.0-amd64 Version: 4.0.1-1 Severity: normal My 32Bit Dom0-crashes with error "Out of SW-IOMMU space for 65536 bytes" after doing moderate I/O on the local storage, which is a software-raid1 over 3 harddrives, connected to the builtin Perc H200 controller with ext3-fs.

Keir, below/attached patch is necessary to allow SVM partitions to boot unmodified guests with xen-unstable.hg c/s 8961. c/s 8822 and 8828 (some necessary evtchn modifications) cause SVM partitions to fail with "lost interrupt" hda error during boot. We currently do not understand why these modifications are necessary and in fact, a race occurs with one part of the patch (added

This patch cleans up some 80-odd warnings I was seeing when compiling the xenpci driver, all completely trivial. It also replaces the use of asm for calling cpuid with the __cpuid compiler intrinsic, and modifies calling code accordingly. I''m pretty sure my mailer going to mangle the inline patch (below) so I''m attaching the pristine version. (will try to fix for next time) --

This set of patches adds the support for acceleration plugins to the netfront/netback drivers. These plugins are intended to support virtualisable network hardware that can be directly accessed from the guest, bypassing dom0. This is in response to the RFC we posted to xen-devel with an outline of our approach at the end of September. To follow will be another set of patches to provide our

By default, the function add_to_physmap_one set mfn to 0. Some code paths that result to an error, continue and the map the mfn 0 (valid on ARM) to the slot given by the guest. To fix the problem, return directly an error if sanity check has failed.

Hi, I''m trying to boot up with lot more than 32 vcpus on this very large box. I overcame vcpu_info[MAX_VIRT_CPUS] by doing vcpu placement hypercall in guest, but now running into evt channel limit (lots of devices): unsigned long evtchn_pending[sizeof(unsigned long) * 8]; which limits to 512 max for my 64bit dom0. The only recourse seems to create a new struct shared_info_v2{},
