Not sure I did the xen log correctly. I have this in /etc/default/grub now: GRUB_CMDLINE_XEN_DEFAULT="loglvl=all" And now here is xen dmesg: root at xen-3:~# xl dmesg (XEN) Xen version 4.3.0 (Debian 4.3.0-3+b1) (buildd-binet at buildd.debian.org) (gcc (Debian 4.8.2-8) 4.8.2) debug=n Wed Dec 4 07:43:54 UTC 2013 (XEN) Bootloader: GRUB 2.00-22 (XEN) Command line: placeholder

Hi Folks: I run into a problem when enabling Xen in next generation server platforms with Xen c/s is 21380. Xen reported "CPU Not responding" when booting up 32 CPUs( 2 sockets with 8 cores/16threads total). The log files belonging showed something wrong with APCI. So I added x2apic=0 in the xen grub line, but the symptom remained. However, Native RHEL5.5 can

This issue I am encountering seems to only happen on multi-socket machines. It also does not help that the only multi-socket box I have is an Romley-EP (so two socket SandyBridge CPUs). The other SandyBridge boxes I''ve (one socket) are not showing this. Granted they are also a different model (42). The problem is that when I run ''perf top'' within an SMP PVHVM guest,

During boot of dom0, I get the following. Box is remote, so I''m now waiting for proxy power button pusher ;-) tg3 init fails doing dma_alloc_coherent (I assume this is from tg3_init_one -> tg3_test_dma -> pci_alloc_consistent -> dma_alloc_coherent). Looks like an issue with the amount of memory in dom0. Is this known? thanks, -chris root (hd0,0) Filesystem type is ext2fs,

Hi Konrad, I just tried to boot a 3.8.0-rc0 kernel (last commit: 7313264b899bbf3988841296265a6e0e8a7b6521) as dom0 on my machine with current xen-unstable. The boot stalls: [ 0.000000] ACPI: PM-Timer IO Port: 0x808 [ 0.000000] ACPI: Local APIC address 0xfee00000 [ 0.000000] ACPI: LAPIC (acpi_id[0x01] lapic_id[0x00] enabled) [ 0.000000] ACPI: LAPIC (acpi_id[0x02] lapic_id[0x01]

Dom0 uses this hypercall to pass ACPI information to Xen. It is not very uncommon for more cpus to be listed in the ACPI tables than are present on the system, particularly on systems with a common BIOS for a 2 and 4 socket server varients. As Dom0 does not control the number of entries in the ACPI tables, and is required to pass everything it finds to Xen, reduce the ERR to an INFO.

Remove unused and pointless bits from mpparse.c (and other files where they are related to it). Of what remains, move whatever possible into .init.*, and some data items into .data.read_mostly.

Hi there! I tried installing Xen 3.0.2 on my Intel Core Duo notebook, but when i boot Xen i got this bad message: Panic on CPU 0 IOAPI[1] unable to change apic_id Resetting in 5 seconds Unknown interrupt What is the cause? Is that fixed? How can i fix it? Many thanx who can help... Bye bye, Paolo Scaffardi http://www.arsenio.net http://www.sognilucidi.it http://www.artigianidelsughero.it

From: Suravee Suthikulpanit <suravee.suthikulpanit@amd.com> This patch add an additional logic to check for the often case when the special->handle is not initialized due to firmware bugs. but the special->usedid is correct. If users overide this using the command line option ivrs_ioapic, then it should use the value instead. --- This patch is supposed to follow the patches:

Hi, I''m using Xen 3.2.1 with 2.6.26 as Dom0 and DomU in the x86_64 Versions/Builds as provided by Debian Lenny. I noticed that when using "jiffies" as clocksource, the resolution of the timers in a DomU is 4ms, e.g. ping shows only runtimes in 4ms increments [1]. When using "xen" the resolution is fine (didn''t make exact measurements) but xen is a no-go

However, I need more RAM -- but cannot remember if all (four) RAM sockets are populated (which would mean to buy higher capacity modules) or if there are two slots left to use.

Implement a simple Xen APIC module and use it to deliver MSI/MSIX for Xen HVM guests.

All. I am running Xen on an ES7000 system with 4 procs and 4 GB memory. I am running Suse Sles-9 (32-bit) on the machine. I have compiled Xen (the tip on the unstable tree : 6552) with PAE enabled (XEN_TARGET_X86_PAE=y). The system boots fine. I started xend and when I tried to bring up a virtual machine, the system gave me the following error on the command line. On the serial port, I saw an
