When using a para-virtualized guest, which network type should be used? -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.centos.org/pipermail/centos-virt/attachments/20090725/77b15c3a/attachment-0006.html>

Me again. The ASUS P5N32-SLI motherboard in my new machine has dual NICs but CentOS has only detected one of them. I've tried rebooting with the network plugged in only to the second one, but kudzu still doesn't find it. Any suggestions?

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 don't have ifcfg-eth1 in my /etc/sysconfig/network-scripts. But when I do ifconfig eth1 I can see output as below. If I do ifconfig eth12 , I don't see anything which i am assume is normal. eth1 Link encap:Ethernet HWaddr 00:24:E8:44:DB:CC BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0

Hi , I would like to assign a Network Interface card to Physical Slot X in the virtual machine, I have gone through the XML file definition[Now i have some idea on how to position the Network Interface in Logical PCI Slot.] I am NOT interested in using a PCI Pass-through from the Host. currently running Fedora 19 with libvirt 1.2.0 I would like to create an network interface card on

I went to the site to subscribe again and ended up watching some of Jeremy's Google interviews. I particularly enjoyed the interview with James and the bow tie lesson at the end. :) So anyway, I recently upgraded my home network to end-to-end GbE. My clients are Windows XP SP3 w/hot fixes, and my Samba server is 3.5.6 atop vanilla kernel.org Linux 3.2.6 and Debian 6.0.6. With FDX fast

I have a hardware here with 9 NICs (8 of them on-board) and I want to set up 8 NICs as real network interfaces, one for each xen domain. The 9th NIC should be Domain-0 which is working well. Currently I have only set up one domain which is running in bridged mode at the moment. I am currently trying to set up a second domain which uses eth2 but I didn''t succeed. I want to get the

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

Hi Yum has just updated 5 of my Linux boxes running CentOS 4.3 to the 2.6.9-42 kernel. All is well on four of the boxes, but on the fifth the network card (eth0) will not work. I've downgraded the kernel to the previous version and the network card works fine again. I've tried removing and re-installing the new kernel, but the network card won't work with it. The details of the

I''m playing around with VLAN''s and I have a VLAN capable (layer 2) smart switch. I see a steady stream of martians in the logfile if I have the routefilter option set on the loc zone interfaces in /etc/shorewall/interfaces. I have two interfaces in the loc zone, eth1 and vlan2 respectively. vlan2 is an 802.1q trunk going towards the switch. Is this the expected behavior in

Hi, I have a transition matrix T for which I want to find the steady state matrix for. This could be approximated by taking T^n , for large n. T= [ 0.8797 0.0382 0.0527 0.0008 0.0212 0.8002 0.0041 0.0143 0.0981 0.0273 0.8802 0.0527 0.0010 0.1343 0.0630 0.9322] According to a text book I have T^200 should have reached the steady state L L

Hi, I have a 64bit Debian Lenny server with two physical network interfaces, one is connected to a switch without VLANs (eth0), the other (eth1) is connected to a switch with tagged VLANs (eth1). I''m running a couple of paravirtualized VMs that have no problem using the eth0 interface (bridged). I''m also running a couple of fully virtualized VMs, one being a Linux box (with a

May be a little bit off topic, but this gave me hard laugh: http://www.theregister.co.uk/2010/09/24/sysadmin_file_tools/ Windows admins use a virtualized CentOS machine to copy files because their own tools are not able to handle copying a bigger amount of data. :) Cheers, Timo

Hey folks, I had some general questions and when reading through the list archives I came across an iSCSI discussion back in February where a couple of individuals were going back and forth about drafting up a "best practices" doc and putting it into a wiki. Did that ever happen? And if so, where is it? Now my questions : We are not using iSCIS yet at work but I see a few places

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

Is there anyway to get gigabit networking for a fully virtualized guest? I''ve tried searching for this one, but all I get are results about gigabit networking for the host / dom0, nothing for domU.

Here's a weird one that may have nothing to do with Samba and more to do with network frame sizes. I have recently upgraded the network infrastructure to support gigabit speeds. - OSX Tiger to OSX Tiger file transfers operate at gigabit speeds. - Samba 3.0.23C (Suse 10) to OSX Tiger file transfers operate at gigabit speeds. - BUT OSX Tiger to Samba 3.0.23C (Suse 10) file transfers

Everyone, Most of the time I am over my head in trying to troubleshoot problems. However, after reading manuals, man pages, and getting advice from this list I have been able to work my way through difficulties, and at the end, I usually have a better understanding of what 'is going on'. I can only hope this method will work on this problem too. I have been chasing a problem with a

We have an application that has many processing threads writing more than a billion files ranging from 2KB ? 50KB, with 50% under 8KB (currently there are 700 million files). The files are never deleted or modified ? they are written once, and read infrequently. The files are hashed so that they are evenly distributed across ~1,000,000 subdirectories up to 3 levels deep, with up to 1000 files
