similar to: Network Performence Scoping

I am looking to scope a server running under XEN hypervisor, from a network perspective. The virtual machines will be Linux Apache web servers with fairly high network trafic receiving small requests. My questions are: How many of these virtual machine I can/Should I bind to a single physical Gigabit NIC ? Will it be possible to fully use the gigabit interface ? Up to how many gigabits NIC XEN

Hello All, I have one CentOS 6 KVM virtualization server that I built around a year ago (best I can tell it was in October 2012) at which time I would have been installing 6.3 [0]. That particular install used the Consistent Network Device Naming [1] conventions (PCIe NICs are p1p1, p1p2). I started to build out a new KVM virt server (kickstarting a 6.4 install now as compared to 6.3 back then)

Hi, I would like to build new router with 3 Gigabit Ethernet card. Need I dual procesor system or not ? I would like to have trafic controling (htb or cbq/sfq) and firewall (iptables) on this router. Can you recommend me some good motherborad with 64-bit PCI-X ? -- `)_|_('' PSIkappa I k psi _at_ atlantis.sk

I'm running 7.0-RELEASE-i386 on Jetway's NC92-N230 mainboard. The board has one integrated RTL8168/8111 gigabit NIC as well as an expansion board with three RTL8168/8111 NICs. Why would the three NICs work while the onboard NIC does not? none2@pci0:1:0:0: class=0x020000 card=0x816810ec chip=0x816810ec rev=0x02 hdr=0x00 vendor = 'Realtek Semiconductor' device

Trey, The Compaq NC7770 PCI-X Gigabit Server Adapter supports PXE: http://www.compaq.com/products/servers/networking/NC7770/ This NIC will be available next month. Also, our strategy is to support PXE on all ProLiant server embedded NICs (10/100/1000) beginning with G2 (generation2) models. Also, most existing DL and all BL servers currently support PXE on their embedded (10/100) NICs. Let

Hello I have some problems with 3Com nics, after a upgrade from 5.5-STABLE to 6.4-STABLE. This machine has two 3com nics (one is LAN other is WAN) and i see too much "watchdog timeout" on both cards. This on/off up/down on cards, affect the interrupt to clients that are downloading from apache web server, especially on large files. --------------------------------------------

I've got a HP dv8000 laptop. Setting up the wpi driver for wireless freezes the system on boot with the following error: wpi0 requested unsupported memory range wpi0: could not allocate memory resource It lists a pcbi device (pcbi4 i think) and an actual memory range, but since I have to reboot using kernel.old the /var/run/dmesg.boot is wiped with the info. Is there anyway to grab the

Hello, I'm running Samba 4.4.5 with enabled SMB Multichannel. The Linux server has two 1GBit/s NICs and for testing purposes I've shared a tmpfs mountpoint with 2GiB and ~2GiB large test-file. My Windows 10 host has one dual-port 1GBit/s NIC, and if both interfaces are enabled, Get-SmbMultichannelConnection lists active multichannel connections to my Linux SMB server. If I disable one

I have two servers with identical hardware ... TYAN i3210w system boards with dual intel gigabit interfaces, and a PCI intel gigabit nic. I'm running Centos 5.4, x86_64, 2.6.18-164.6.1.el5 Every other time I reboot, the nics initialize in a different order. anaconda had setup /etc/modprobe.conf with alias lines for the cards: alias eth0 e1000 alias eth1 e1000e alias eth2 e1000e However,

Hello, I've been having spurrious crash troubles with this box a while now and I haven't been able to figure out why. I've ran a couple memtest passes on it and it didn't pick up anything. Here's a backtrace I've been able to obtain. The kernel config is at the end. It's the generic kernel with ULE. I'm following chapter 11 of the developers' handbook, so if

Dear Xen Users, I have a rhel5 dom0 machine with four nics, two public and two private. My goal is to run two xen instances, a fully virtualized rhel4(with a custom kernel, hence the fully virtualized) and a paravirtualized rhel5. Each instance will need one public and one private nic with gigabit connectivity. At the moment I''m simply bridging two nics to each instance. Is this the

HI, I have been stuck by this problem for the whole week. We just did a simple experiment to test the network performance in xen use the benchmark--iperf. Our NIC is Gigabit, and we got exactly correct data in hostOS--fedoral core 8 without xen running, the bandwidth of the network was 931Mbps. But the problem is, when we start guest OS--fedoral core 8, and running iperf on it, we got data only

Hi, I've set up a bridge using the 2.6.11.6 kernel. The machine is running Debian testing with three NICs in it. eth0 is a standard 100Mb Intel NIC, eth1 and eth2 are both Intel gigabit cards using the e1000 driver. I tested everything at 100Mb and it worked fine. I moved the machine into production, eth1 plugging into a dumb 100Mb D-link switch, eth2 plugging into a shiney new Cisco

Hi all, I have a machine that won't boot syslinux 4.02 but will boot syslinux 3.53. We've installed syslinux 4.02 on a number of machines but only this one has a problem. The problem is that the machine hangs entirely after printing "boot:" on the tty. The stanza being booted in /boot/extlinux.conf is: label xe # XenServer kernel mboot.c32 append /boot/xen.gz
