Hi, When using lapic as timer source the hypervisor delivers timer interrupts late. In the source xen/arch/x86/hvm/vpt.c function create_periodic_time creates a timer element with a "bonus" of 50% of the desired time until the interrupt: pt->scheduled = NOW() + period; /* * Offset LAPIC ticks from other timer ticks. Otherwise guests which use * LAPIC ticks for

Hi, on a Nehalem system with VT-d enabled we are seeing strange ACPI-Table contents, especially a corrupted DMAR entry. The hypervisor shows following data on boot: (XEN) ACPI: RSDP 000F80E0, 0024 (r2 PTLTD ) (XEN) ACPI: XSDT BF7C469E, 00D4 (r1 PTLTD XSDT 60000 LTP 0) (XEN) ACPI: FACP BF7C9CC9, 00F4 (r3 FSC TYLERBRG 60000 PTL F4240) (XEN) ACPI: DSDT BF7C4772, 54D3 (r1

Hi, we are experiencing significant performance degradation after live migration of hvm domains in Xen 4.0 (SLES11 SP1): after live migration the performance is dropping to less than 90%. I did a backport of cs 23420-23423 and the performance is okay now. I would like to request to include these changesets in 4.0 and 4.1. The backport is quite trivial, I can send patches if you are willing to

Hi, the implementation of xl cpupool-numa-split is broken. It basically deals with only one poolid, but there are two to consider: the one from the original root CPUpool, the other from the newly created one. On my machine the current output looks like: root@dosorca:/data/images# xl cpupool-numa-split libxl: error: libxl.c:2803:libxl_create_cpupool Could not create cpupool error on creating

Hello, My testing machine has 2 quad-core CPU (It supports hyperthreading, but i disable it in BIOS). I uses Xen 4.0.1 as the hypervisor. When I use 8 VMs to conduct a test, CPU affinity of the VMs is very strange. Like this: vm_name vcpu_num cpu_affinity Domain-0 8 any VM1 4 1,3,5,7 VM2 4 1,3,5,7 VM3 4 1,3,5,7 VM4 4

cpu_possible_mask and related macros are no longer used in Xen. Remove them and adjust comments accordingly.

Hi, I''ve got a strange problem with XEN: I''m testing a 64-bit HVM-domain (a little OS written by me) with XEN 3.0.4 changeset 13138 on x86_64 (Dom0 and XEN taken from SLES 10 SP1). Always at the same point I get a page fault (which is okay) in PL=3 with strange interrupt data on the stack: the EIP is okay, but the CS saved is the TSS instead of my 64-bit user CS selector. I

hello, I would like to map (Read/Write) pages owned by a HVM guest from my Dom0 Linux kernel module. I have access to the "machine frame numbers" of these pages. 1. What is the right interface to do this? kmap needs ''struct page'' ptrs which I doubt exist for pages owned by a HVM guest. Is there a hypercall to do this then? 2. Do I need to modify the HVM behavior in

Hi I need to use hypercalls from HVM domain (e.g. HYPERVISOR_add_to_physmap). However, it does not work when I am trying to invoke it from HVM Linux guest. Basically, I don''t see that anything happens on hypervisor''s side. I also grep''ed the guest code for ''vmmcall''/''vmcall'' and did not find anything. Is it possible to do it at all?

Hello list, i did a quite sucessfull net rpc vampire but one promblem remains. Everything is fine, but the user group memberships aren't restored. Only alle primary group member ships are restored. every user is in the primgrp (4126 Users). All Groups (2659) are restored including sids. but no membership is restored! I don't know why. here's my command: net rpc vampire -l -S nt4pdc

Hello everybody, i upgraded last week a samba installation from version 3.0.9 to version 3.0.14a using the rpms from ftp.sernet.de (sles9-i386 tree). I just installed the rpms as usual with the rpm -e and rpm -i and everything seems to be fine. But there was no browsing possible. due to a small timeslot i had to downgrade to 3.0.9 then which worked very fine. the problem is that i have to find

Basic x86 support [1] for running Linux as secondary Jailhouse [2] guest is currently pending in the tip tree. This builds on top and enhances the PCI support for x86 and also ARM guests (ARM[64] does not require platform patches and works already). Key elements of this series are: - detection of Jailhouse via device tree hypervisor node - function-level PCI scan if Jailhouse is detected -

Hello Folks, i'have a problem share a directory to both unix(nfs) and windows(samba). The main problem is, that the rights are associated to winbind groups. the user in question can access the files from windows correctly and locally correctly (via su -$USER). If i mount the directory via nfs and make a su - $USER i can't write to the directory. when calling getfacl $DIR i can see, that

Hello everybody, had anyone of you problems with winbind and tdbfiles, when upgrading from 3.0.14a to 3.0.20a? The Symptom was: After upgrading to 3.0.20a the idmapping was corrupt. Although 3.0.20a runs fine, none of the idmaping was resolved correctly. Downgrading to 3.0.14a "restored" the idmaps. tdbdump showed me the same idmappings, therefor i think winbind wasn't able

Reduce special casing of xen_cpuid() by using cpu capabilities instead of faked cpuid nodes. This cleanup enables us remove the hypervisor specific set_cpu_features callback as the same effect can be reached via setup_[clear|force]_cpu_cap(). Removing the rest faked nodes from xen_cpuid() requires some more work as the remaining cases (mwait leafs and extended topology info) have to be handled
