Konrad, et al, I am seeing visual corruption (almost like an interlacing problem) with i915 under Xen on some platforms using linux-3.8. See attached file for an example of the visual corruption. This particular platform is an HP Elitebook 2540p The same kernel and ramdisk, when booted as native linux does not show this corruption. dmesg is attached, as well (out.txt) - but I did not see

Jan, I was given a machine to diagnose a boot problem on xen 4.3, that used to work on 4.2, and have bisected to the following changeset: commit d0d4635d034f202bb401a6efa3ba61530f3854ab Author: Jan Beulich <jbeulich@suse.com> Date: Thu Nov 22 10:47:58 2012 +0100 implement vmap() ... and use it as basis for a proper ioremap() on x86.

Hi, we are currently working on getting windows working on your xen servers. but we are facing a severe problem where dom0 and all domus hang for 1-5 seconds from time to time. we think it is probably because of disk i/o, because top sometimes says 100% wa (waiting on io) during the hang. dom0 has cpu 0 for exclusive use and the windows vms use cpu 1 to 7. should we give dom0 more than once

Hi, I have been receiving messages on a new DomU''s kern.log. I''ve done a lot of googling, but haven''t came up with anything very useful, at least not in a Xen context. I was wondering if anyone had any suggestions about what could be wrong. From everything I have read, there should be a stack trace included, but I am not seeing one. Thanks in advance, Ian. on

When booting a recently compiled Xen 4.2 on Ubuntu 12.04, dom0 crashes. I''ve included a serial console log below. I''ve used: Xen 4.2 unstable rev. 25483, compiled on the same machine. I had to apply the AT_EMPTY_PATH patch from http://lists.gnu.org/archive/html/qemu-devel/2012-02/msg03460.html to get it to compile. Linux 3.2.0-25, which is the default kernel in Ubuntu''s

Am considering a new laptop, and I wonder if anyone here can share their Xen experiences with the newest Core 2 Duo CPUs, ref http://www.intel.com/products/processor/core2duo/specifications.htm The list at http://wiki.xensource.com/xenwiki/HVM_Compatible_Processors doesn''t include any Core 2 Duos. Does that mean that people have had problems, or is the wiki just not up to date? I gather

Hello, I''m getting many "Error getting mfn" on a xen4.1.3 with dom0 3.4.11 x86_32.

x86:x2apic: Disable x2apic on x86-32 permanently x2apic initialization on x86_32 uses vcpu pointer before it is initialized. As x2apic is unlikely to be used on x86_32, this patch disables x2apic permanently on x86_32. It also asserts the sanity of vcpu pointer before dereference to prevent further misuse.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi list, I have an IBM xseries 345, running CentOS 5.3, hosting a few Xen domUs. 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. However, I'd like (and think that it's possible, but don't remember how) to

Hello, I originally posted this to xen-users, but someone suggested I post it here. I am having ACPI problems on a PenguinComputing Altus1600 system. It has 2x dual core Opteron 2210 processors. The system boots with a standard Debian or Ubuntu SMP kernel, with ACPI enabled. However the xen live cd, binary xen install, as well as my own custom compile of xen 3.0.4 from source will not boot.

It seems that VCPU system time isn''t monotonic (using 3.0.4). It seems it might be correlated to when a VCPU is switched across real CPUs but I haven''t conclusively proved that. But e.g.: { old = { time = { version = 0x4ec pad0 = 0xe8e0 tsc_timestamp = 0x22cc8398b7194 system_time =

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,
