Package: xen-utils-common Version: 3.0+hg11292-2 Severity: normal After a recent etch upgrade (2.6.17, xen-3.0.2) I was unable to "xm create" until I "modprobe netloop nloopbacks=10" Error was network-bridge couln't create vif interface (backend not found). brctl addbr ... fails because of no free netloop device. passing more nloopbacks device to the module fixed the

Hi, I want to switch my server into a Xen instance. Right now there are 10 vlans ending up at the server. For each service that the server provides, there is an alias IP address on each of the vlan interfaces to serve the clients. I want ot install xen, and divide the services into 4 virtual nodes. The dom0 machine has three network interfaces, eth0, eth1, eth2. eth0 and eth1 are bonded

Hi there, I am using xen hypervisor for analysing guest to guest communication throughput. I have Quad Core Intel Xeon server with F11 installed on it. My Dom0 and DomU specs are: Dom0: #uname -ra Linux HPCNL-SR-2 2.6.30-rc6-tip #1 SMP Tue Aug 25 12:26:16 PKST 2009 i686 i686 i386 GNU/Linux DomU: # uname -ra Linux F11-G5S2 2.6.29.4-167.fc11.i686.PAE #1 SMP Wed May 27 17:28:22 EDT 2009 i686 i686

Hi, I was hoping someone on this forums could help me out with a problem I was facing with Xen. When I compiled the kernel for Xen-3.1.3 using "make world"(I know this is an old version but I need to use it for some compatibility issues), the kernel was missing the Xen netloop module. There was no /kernel/drivers/xen/netback/netloop.ko in the newly compiled kernel. I think we would

Dear all:     I met a problem recently.     I am using Xen to build my virtual network, and vlan ID is used to seprate different virtual networks. At first I built the network bridge with a physical network device with vlan as its port directly. Then my virtual host could send and recieve normal packets while these packets are encapsulated in vlan ethernet frames once they come into physical

You are very welcome. One thing that I am working on now involves removing the step toward the beginning: xe pif-reconfigure-ip uuid=<UUID of the bond created above> mode=static gateway=<GATEWAY> IP=<IP ADDRESS> netmask=<NETMASK> DNS=<DNS SERVER ADDRESS> I do not believe that this step is necessary since we will not use the pif directly. We will use

Package: xen-utils-common Version: 4.0.0-1 Severity: normal After upgrading xen-utils-common from 3.4.2-4 to 4.0.0-1, I could not create a guest domain defined with a DRBD file type. The xm create command would fail with "Error: Device 51713 (vbd) could not be connected. Hotplug scripts not working.". After some research I realized the /etc/xen/scripts/block-drbd helper script was

Hi, I try to get networking running with xen 3.2, but it seems I fail miserably. I am on sles10sp1, with xen 3.2.0, and kernel rpm''s installed from SP2. I configured in /etc/sysconfig/network the NETWORK_LIST: NETWORK_LIST="bridge,0,default,00:DE:AD:BE:EF,192.168.8.13/24,dhcp-off" but an ifconfig xenbr0 still shows the mac address of peth0 fe:ff:ff:ff:ff:ff. Initially, I

Hi list, since release 5.3 all kernels ignore options netloop nloopbacks=<n> within /etc/modprobe.conf If <n> is smaller than four there are always four vifs created. If <n> is bigger than four the appropriate number of vifs are created. Is this expected/new/feature/bug? Henry

Hello, I have a xen server that needs to run a domU on a different vlan than xen''s. I have configured my switch (a cisco catalyst) to tag every untagged packet to the default vlan (the one in which is dom0) and to accept tagged packets (for that domU). I have xenbr0 linked with the eth0, the default network. Then I run * vconfig add eth0 101 -> To create a virtual interface with

While I am still in the process of working through this here are the steps I am taking to set up each machine. 1) Since each of my servers have multiple NIC ports I bond them together (see page 34 of the Administrators Guide) first. This is best down from the physical server and not via the remote console. If you do it remotely you will then have to reconfigure the management port before

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

Hi, I''m running Nevada 75a configured as dom0. I added a domU HVM running Nevada 75a, on a Sun X4600 with 8 ADM Dual cores. I can get the domU installed and configured, however, I can not get any network connectivity. I followed the steps accoding to documents on Open Solaris. I also followed some of the threads of the list to verify the configuration, but I can not fix the

--- In english --- Hello! I am to implement a new architecture of the network in my company but I do not know right where to start ... need help! Currently 90% of my servers are virtual machines under Xen. I have many valid IP networks and all Hypervisors are configured in bridge mode, to simplify. We have 3 VMWare ESX Hypervisor also in bridge mode. Some networks are exclusive to certain

Hi, with reference to RH BZ#567540 [0], this patch makes the netloop module permanent (like netback is currently). It reverts parts of xen-unstable c/s 9019:271cb04a4f2b [1] [2] (though that has a typo: "__init clean_loopback", so it was probably changed later too). The patch fixes the problem of "rmmod netloop" hanging, resulting in blocked tasks and inability to shut down

Hi, I''m using opensolaris 2008.05, updated to snv_94. On dom0, I have : - bnx1 connected to switch as trunk - bnx128001, vlan 128 on bnx1, allocated an IP address and serve as dom0''s primary network interface. I created a RHEL5 domU with this vif config vif = [ ''mac=00:16:XX:XX:XX:XX, bridge=bnx128001'' ] but domU startup failed with Error: Device 0 (vif)

Hello everyone, Recently I have been testing my customized Xen 4.2 networking setup. It works pretty good and I would like to share it with anyone who is interested. The relevant files can be found here: https://github.com/slacks42/xenscripts Benefit: configure the Xen related networking devices with one understandable bash script. Please note that this is all still work in progress. For

Hi, I''m playing with xen from a couple of weeks, all standard configurations work fine within my suse box. But trying to become closer to the xen philosophy I can''t understand the issues which drown developers to use netloop module instead of the tap one. thank''s in advance _______________________________________________ Xen-users mailing list

It appears that this bug is caused by the netloop kernel module not being automatically loaded. xn
