Please help: domU becomes unresponsive
Hi all, sorry to intrude on xen-devel, but I think I need direction from the expertise here. I''ve admin''d Xen servers of various flavors for a couple years, but never seen this before. After a period ranging from several hours to several days, my primary database and development DomU completely locks up. Net disconnects, but CPU(sec) continues to tick in xentop. No errors, and

Xen-unstable kernel panics on boot
I have compiled xen-unstable from source and I am unable to boot the kernel that this creates. It appears to not be able to find my logical volumes to mount the root volume. Shortly after this, the kernel panics and the machine reboots. Is there any option I can use when building the kernel to stop this reboot after the panic so that I can find out what is causing it? I know about

Bare Metal Installation of Xen
Is there a documented approach somewhere for performing an unattended ''bare metal'' install of Xen? The Xen Users'' Manual describes an installation flow that requires a host OS on the target machine. This host OS is used for installation of Xen, but Xen does not execute "on top of" this OS (rather Xen executes directly "on top of" the hardware

non-bootable dvd image
Hi all; I downloaded the centos 4.3 image onto my linux box and used k3b to burn a DVD iso image. It seemed to work fine. I have an SuSE laptop and I want to setup a CentOS VM via Vmware 5.5 If I insert the dvd and boot the new vm I get 'no operating system found' It seems to be a non-bootable dvd. Is there something additional I need to do when burning the dvd image to make it

recommend benchmarking SW
Hey folks, We've got some new hardware and are trying to figure out what best to do with it. Either run CentOS right on the bare metal, or virtualize, or several combination options. Mainly looking at : - CentOS on bare metal - CentOS on ESXi 4.0 with local disk - CentOS on ESXi with 1 VM running Openfiler to serve disk to other VMs And want to benchmark these 3 scenarios So far all we

Cacti-based monitoring
Hi, I maintain several dom0 hosts, and I would like to monitor the following with Cacti: * the overall hypervisor CPU usage * available hypervisor memory (e.g. memory that can be allocated to new domUs) and maybe: * domU CPU usage But the latter is not as important to me right now. Anyone have any pointers on how I might do this? My knowledge of Cacti is very basic. Basically: has anyone

How to detect whether running on VMware?
Does anyone know how a program, script or shell user can best determine whether the machine is running on bare metal or is a VMware guest? Cheers Tony -- Tony Mountifield Work: tony at softins.co.uk - http://www.softins.co.uk Play: tony at mountifield.org - http://tony.mountifield.org

[PATCH v3 0/2] guard virt_spin_lock() with a static key
With virt_spin_lock() being guarded by a static key the bare metal case can be optimized by patching the call away completely. In case a kernel running as a guest it can decide whether to use paravitualized spinlocks, the current fallback to the unfair test-and-set scheme, or to mimic the bare metal behavior. V3: - remove test for hypervisor environment from virt_spin_lock(9 as suggested by

Kickstart GUI?

bare-metal backup before update--options?
Hi all! I'm a "nervous nellie", I have not yet updated my 7.5 desktop to 7.6 because (1) it has an Nvidia card, and (2) I've heard of problems upgrading on top of software RAID (using RAID1 with 2 drives). I need to upgrade it to stay secure, and I want to do a bare-metal backup first (so I can put it all back as it now is, in case it explodes in my face), so I'm trying to

Linux DomU vs Bare Metal performance issues
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I''m trying to diagnose a reasonably large performance drop between two ostensibly similar servers; one running CentOS 5.5 on bare metal, the other running Fedora 14 as a Xen DomU under CentOS 5.5 (Xen 3.1.2-194.26.1.el5) I have a pair of older Dell PowerEdge 1750 servers, each with 4GB ram and 2x 2.4GHz Xeon CPU''s with

Need kernel-debuginfo-2.6.9-67.0.20.EL.x86_64.rpm
Short story: Would it be possible to get kernel-debuginfo-2.6.9-67.0.20.EL.x86_64.rpm on di.c.o? I have a need to run crash on a 2.6.9-67.0.20.ELxenU xm dump-core. Long story: Two Dell 6950 (now called R905, 4 Dual-Core AMD Opteron 8200 series) heartbeat/drbd nodes running the stock CentOS 5.2 Dom0. The domU's are the only resources in heartbeat.

Enable Safe Stack for Baremetal?
Hello, I'm assessing the work required to enable Safe Stack for a bare metal target. Looking at compiler-rt/lib/safestack/, the current implementation depends on thread support for mutex & storing unsafe stack pointer. It also need several system calls: gettid, tgkill, mmap, munmap, mprotect. Our target doesn't has all underlying support it needs. My question is: what's the

LLVM on bare-metal
Hi Peter Thank you for your helpful comments, especially on the RPI.  Since my use case is lot simpler than compiling all of Clang, I hopefully can take your experience as a good sign. The RTOS that TI provides for the AM335x actually has pretty complete posix layer and other standard libraries.  However, I am working without any virtual memory subsystem, so no mmap.  However, I was under

Bare Metal vs virtualization
Hello to all: I know this list is generally Linux-only, but I figured I'd try to gain wisdom from those with hard-core Windows needs, too. I was recently pricing out a high-end desktop system for a user who will doing a lot of CAD, Matlab, SolidWorks, and other apps that will utilize a lot of number crunching and video. The quote for the desktop (64-bit Vista is likely), which included 12

[PATCH 0/6] x86: reduce paravirtualized spinlock overhead
Paravirtualized spinlocks produce some overhead even if the kernel is running on bare metal. The main reason are the more complex locking and unlocking functions. Especially unlocking is no longer just one instruction but so complex that it is no longer inlined. This patch series addresses this issue by adding two more pvops functions to reduce the size of the inlined spinlock functions. When
