I come across some problem when using xen-4.1.1-rc1-pre from xen-4.1-testing tree and 2.6.32.36xen linux kernel from git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git. when I use ''xend restart'' , it hangs when kernel dmesg printing ''Bridge firewalling registered'' and the console show below messages: localhost# xend restart Nothing to flush. Cannot

We've just moved one a new server from our sever room, where I built it, to the datacenter. We want to force autoneg off, and tell it gigabit and full duplex. Using ethtool, I get no errors setting the speed or duplex. HOWEVER, autoneg on works... and autoneg off utterly refuses to work, and gives: ethtool -s eth0 autoneg off Cannot set new settings: Invalid argument not setting autoneg

Greetings, I recently installed CentOS 5 on Dell PE 1750 server. I have noticed that the speed and duplex settings are 100 Half Duplex. I tried to change the duplex settings to full, but no success. I got the error message "Cannot get current device settings: Operation not supported". Does anyone else experience this issue?. Below is the error message and some more details about my box.

Two problems I hope to solve: 1. The switch being used has autoneg off and has port set to 100 full duplex. 2. Many times NIC fails to come up properly during PXE boot: r8169: eth0: link down ADDRCONF(NETDEV_UP): eth0: link is not ready I can't use ethtool to disable autoneg because the nic driver is built into a bzImage. The root fs is currently being mounted via nfs during pxeboot at

I have no output in the logs, but /etc/init.d/network restart fixes the issue. I am rsync/scp (10GB) data from one 100MB Full duplex host to an ASUS M3A78-EM (RTL8111B/C). It locks up around the 1.5GB Tx mark. If I ethtool -s eth0 autoneg off speed 100 duplex full it does not happen again. Ideas? -- -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- -

I've got a Dell Precision Workstation 490 with 64-bit Centos 5, fully updated, with an on-board Broadcom 57xx gigabit Ethernet controller, updated BIOS, 1 GB switch, and /var/log/messages and dmesg both claim the link is 100 Mb, not 1 GB. I tried setting eth0 to mtu 9000 but got an error in going so. What do I need to do to have the card see 1 gb? Thanks. Scott

I can't explain why 700 msecs aren't enough to avoid timeouts in 100 Mbps networks, but my tests verify it, so I'm writing to the list to request that you increase the default timeo to at least 30, or to 600 which is the default for `mount -t nfs`. How to reproduce: 1) Cabling: server <=> 100 Mbps switch <=> client Alternatively, one can use a 1000 Mbps switch and

I just kickstarted a new machine with the latest CentOS 6.2 files, including kernel 2.6.32-220.13.1.el6.x86_64.

Hi Michael: Sorry to brother. But I''ve been suffered this issue quite a long time. My test environment is 2.6.32.36 + xen 4.0.1 + bnx2, 2.3. Also cpu idle is disabled in grub. Grub info: title Red Hat Enterprise Linux Server (2.6.32.36xen) kernel /xen-4.0.1.gz iommu=off x2apic=off console=com1,vga com1=115200,8n1 noreboot cpuidle=0 cpufreq=none

Hi, i test a xen-patched kernel 2.6.31.10 (kernel from kernel.org with the suse patches) on a system with a boradcom net extreme II (5709) nic using the module bnx2. The nic does not run with this kernel. I get: bnx2 0000:01:00.0: map irq failed Any experiences? Best Regards - Michael Schmidt _______________________________________________ Xen-users mailing list

Hello list, I have two differents installation Xen Hypervisor on two identical physical server, on the same switch : The problem is on my new server (Xen 4.0.1 with pvops kernel 2.6.32.24), I have bad performance on bandwidth I have test with a files copy and "iperf". Result iperf average: Transfert Bandwidth XEN-A -> Windows

I have a broadcom bcm5722 and a dual intel pro/1000 pt nic in a dell t110. The setup sees the cards and i put them into automatic mode. After the install no cards are detected at all. Astaro 8.01 detects and utilizes all of these cards just fine. I have also tried ubuntu server 10.04 lts and they work fine. I'm curious if this is a bug with Centos 6?

Hi folks on debian stable I've a default samba file sharing config. Everything works perfectly (almost...) - samba version 3.6.6 >From linux and windows clients (wired and wifi too) when I (i.e. listen musics) often (one time every 4/5 minutes) networks suddenly collapse (for less one second) and immediately goes up. So I've an interrupt of broadcast (this happens also if I use rsync

Hi list ! A memory upgrade (from 2 to 4Gb) on a bunch of IBM LS21 blades has triggered a very weird behavior. I really can't say if this could be PXE related or not - apologies if it isn't. These machines start via PXE and then NFS-mount their root. Following the upgrade, none of them would boot. I've played with the "mem=" kernel option, and the result is : - if mem <

Hi all, I have a problem when from domU I need to configure a network interface. My system configuration is the next: dom0: xen 3.4.3 with 2.6.18-238.9.1.el5xen kernel, making pci back from a network card. All ok. This is the result from "lspci -v -s 09:00.0" 09:00.0 Ethernet controller: Broadcom Corporation NetXtreme II BCM5708 Gigabit Ethernet (rev 12) Subsystem: Broadcom

Hoping someone else has seen this before. I have a few dozen Dell R610 systems with CentOS 5.2 that are using kernels from 5.3 and 5.4 (2.6.18-128.1.10.el5 & 2.6.18-164.6.1.el5), that at random lose layer 2 network connectivity either partially or totally. Running tcpdump on the interface reveals only ARP broadcasts, no responses. Switch reports no packets being received on the interface.

I totally agree with Luc Boudreau about this problem. On modern branded server they ALL use Broadcom chipset... I must admit that: a) lot of people are experiencing the problem but can tolerate it or b) someone already experienced this problem and solved it Lets'' approach the problem pragmatically... just start with a survey on the list. ... hope we solve this issue soon.

Additional question: I noticed on the HP Website that the latest version of "CPQPOWER.MIB" (1.76, dated Sept. 19, 2013) was more recent than the related file (./drivers/compaq-mib.c) in the NUT driver. Is the MIB structure as implemented on the management card perhaps no longer in line with the NUT driver ? The latest MIB file can be downloaded from the following URL:
