similar to: Xen 3.0 Dom0 Smp enable?

Just wondering if anybody managed to get SMP kernel to boot properly on an old Asus CUV4X-DLS motherboard (older dual P-III)? I had this problem only with this specific motherboard and 2.6 kernels. First time couple of years ago. And again today (I've just installed CentOS4 on a box that used to run RH7.3). Previously those machines were running Red Hat 7.3 (2.4 kernels), and with 2.4

Hi, I am using an ASUS CUV4X-E mother board with a scsi adapter Adaptec AIC-7881U, with one QUANTUM ATLAS_V_18_WLS and MAXTOR 4K040H2, ATA DISK drive connected with a VIA vt82c686a (rev 22) IDE UDMA66 controller. The instalation from original kernel 2.4.7 was ok, but when I upgrade to kernel 2.4.9-31, almost every day I got an error in many process, including apacha, qmail and many

Hello List, I have a problem with an Onborad scsci, that won't boot a isolinux-cd: anyone got a clue? Mainboard is ASUS-CUV4X-DLS with onboard LSI 35c1010-33 Controller. Board-Bios is Award Medaillion 6.0 and Controller Bios is Symbios SDMS v4.0 (4.18.02) The CDRW device to boot from is a Yamaha CRW2100S Rev1.0H I tried Isolinux 1.63 and 1.66 with similar "success": here's

Hi, Updated to current bk today, and my machine stopped booting ... I''ve tracked it down to the apic changes from end of last week. cset 1.1307 boots fine, 1.1308 doesn''t.

Hi everyone, I''m running Xen on an SMP machine. Couple of things: a) is dom0 pinned to a particular CPU? if so which? can I control the choice? b) with the 2.6.10 Xenolinux kernel, cat /proc/cpuinfo shows only a single CPU on my SMP machine. Is this a known problem/behavior? c) if I understand correctly, the BVT scheduler parameters are CPU specific -- they don''t aggregate

Hi, I have following problems compiling bristuff-0.2.0RC8m. Has anybody seen them before and can point me in the right direction? zaphfc/make all: ---------------------- /usr/src/asterisk/bristuff-0.2.0-RC8m/zaphfc/zaphfc.c: In function 'hfc_findCards': /usr/src/asterisk/bristuff-0.2.0-RC8m/zaphfc/zaphfc.c:1000: error: invalid lvalue in assignment make[2]: *** [

hi, i'm trying to get the asynchronous file transfer to work on a FC4 for the latest samba verion (3.0.20b). The things i've done: ./configure --with-aio-support ... included "aio read size = 1" and "aio write size = 1" in the smb.conf file What did i forget?? michiel ========================= uname -a Linux wired11 2.6.12-1.1398_FC4 #1 Fri Jul 15 00:52:32 EDT

Hello, I''m trying to upgrade to using the "boxed" xen supported on FC4 after having it working fine for a while on a manual installation on FC3. I upgraded the host operating system with the FC4 cdroms, and it went mostly fine (after I turned off SElinux...) Now, when I try to boot one of the provided xen kernels, namely: vmlinuz-2.6.12-1.1447_FC4xen0 I always get the warning

Hi all (and Mr. Dunlap in particular), I have a question about the credit (and ultimately credit2) scheduler that I hope you can help me with. I have read the white paper "Scheduler development update" and as much material on the credit scheduler as I can find, but I am still not completely clear on how I should think about the cap. Example scenario: Server hardware: 2

In Xen''s 3.0 documentation is stated: "f you are running IO intensive tasks, its typically better to dedicate either a hyperthread or whole core to running domain 0, and hence pin other domains so that they can''t use CPU 0." http://tx.downloads.xensource.com/downloads/docs/user/#SECTION03400000000000000000 I am mostly running web servers, so it''s IO

Hi All, I''ve been looking through the code and list archives but haven''t found this yet... From dom0, how do you cause a virtual domain to gracefully shutdown? It seems like the machinery is there somewhere, because the hypervisor can do it to dom0... For reference, in UML you do this by putting this in /etc/inittab: ca:12345:ctrlaltdel:/sbin/shutdown -h now ...and then

The unstable tree now includes support for SMP guests, i.e. domains which run on multiple cpus. SMP guests can use between 1 and 32 virtual cpus, even if the machine has fewer physical cpus. The code is highly experimental and performance will improve over time. To use SMP guests: - enable option CONFIG_SMP in the Linux 2.6 kernel config - dom0 will boot with upto the number of physical cpus in

I''ve put together two patches. The first introduces a new dom0_op, set_max_vcpus, which with an associated variable and a check in the VCPUOP handler fixes [1]bug 288. Also included is a new VCPUOP, VCPUOP_create, which handles all of the vcpu creation tasks and leaves initialization and unpausing to VCPUOP_initialize. The separation allows for build-time allocation of vcpus which

Hi, I'm currently thinking of putting more functionalities to Linux server box. Major is Asterisk, but would also like to add video surveillance, home automation and limited (for only domestic up to 4 users) web, file and mailserver apps. I know there are problems running Asterisk with other such apps on same machine - but wonder if I can take advantage of dual processor machine in this

Hi there, I'm currently using CentOS 4.3 (Server edition) in a HP DC 5100 with the IntelR 915GV chipset, powered by a PIV 3.0GHZ. Now I'm facing a problem, with memory. I got myself 4GB of memory, the system bios detects it correctly, but in Linux can only see around 3.5gb memory. With the default kernel-smp (I use hyperthread) or with kernel-hugemem , I have the same results.

Existing credit scheduler is not power aware. To achieve better power saving ability with negligible performance impact, following areas may be tweaked and listed here for comments first. Goal is not to silly save power with sacrifice of performance, e.g. we don''t want to prevent migration when there''re free cpus with some pending runqueues. But when free computing power is
