Hi, we''re running 4 xen servers on our network with multiple network cards. During HighLoad we experince degeneration of inbound network traffic through our loadbalancer. I might found a reason for it, in Dom0 dmesg output looks as follows: [1157421.975910] eth0: received packet with own address as source address [1157421.975957] eth0: received packet with own address as source

I have a centos 4 i386 machine that works like a router (iptables filter, NAT) with two NIC''s. One NIC is connected to my ISP (100 Mbit FTTH), I get a DHCP assigned public IP that changes "sometimes". Most incoming ports are blocked by my ISP. In order to get a fixed IP and open ports, I have to set up a PPTP tunnel to the ISP. The default gw and the NAT''ing goes to

Hi all, On my Suse 9.3 prof. server I had two NIC’s: Eth0 IP 192.168.1.1 Eth1 IP 192.168.2.1 Now I added new NIC (eth2) Eth0 IP 192.168.1.1 Eth1 IP 192.168.2.1 Eth2 IP 192.168.1.2 Now I erased eth0 config and turned off this NIC in motherboard bios Eth1 IP 192.168.2.1 Eth2 IP 192.168.1.2 I renamed eth2 to eth0 Eth1 IP 192.168.2.1 Eth0 IP 192.168.1.2 And, finally I

Hey :) I have recently set up VPN links between 3 subnets. I can ping back and forth between all of the computers just fine, and samba works on all but one subnet. The problem is that I am unable to use the VPN to browse computers on the office network. I can browse them locally from the office, and I can browse other subnets from them (ie. at home, etc), but when I get on another subnet and try

Hello, I have been reading through the documentation and trying to set up a very small VPN as a test for a larger rollout that I would like to complete in the future but cannot get this working. The configuration seems like it should be relatively simple, so I'm most likely missing something basic but I just cannot see what I'm doing wrong. At the moment I am trying to get this working

Hi, I have an existing fedora14 system with two interfaces and several virtual interfaces (as in eth0:0, etc). They are currently configured to not be controlled by NetworkManager, but just standard network services. I've recently started working with libvirtd, so I also have a virbr0 interface as well that has its own network and is masquerading the networking for the single KVM instance I

Hello All, ?I installed Centos 6.5 64 bit on a Dell Vostro 1550 laptop with i3 core. The kernel installed was 2.6.32-431.el6.x86_64. I was not able to compile kernel modules, even after installing the kernel headers, kernel source rpms. ?So I downloaded the kernel linux-3.10.31.tar.xz, extracted it, and did the following: make defconfig change CONFIG_USB_USBNET=y, in the .config. make ?

Hi All, We have a single Centos 5.11 server running a xen hypervisor that went down hard after an extended power outage this weekend. I'm mostly familiar for KVM as that is the majority of what our guests run under and have tried getting up to speed on xen bridging to no avail. The problem is that after the xen server spun back up, the previously defined xen bridges were lost. I've

I''ve setup Xen 3.0.2-2 (binary install) on Ubuntu 6.06, got my domUs up and running, got them connected to the Internet but I can''t even ping to any of these VMs. Now I''m not linux/xen genious but could the problem be that xen-br0 doesn''t have an IPv4 address? (it''s got an IPv6 address) Since I don''t use IPv6 on my network this seems a

CentOS 5.5 Xen "standard" Xen Installation. I have two nics. I just put the second one to DHCP and modified the ifcfg-et01 and so far I am holding, but I am not confident. Prior they were sequential IP Addrs on same subnet. arpwatch has indicated flip flips. I can find no rhyme or reason to predict them. I know I missed I must have missed a step somewhere. I want to keep the

I have a server running Centos 5.2 as a Xen host. A problem that's shown up recently is that at boot, the dom0 interface eth0 doesn't come up properly, with the result that the host is only accessible via remote console. If I execute 'service network restart', eth0 comes up normally, with an IP address and the correct routing. Three guests have been created via virt-manager

Hi I'm very new with Xen (/Debian) I have 2 VMs running Windows: "Arch" and "Sql" -- static IPs VM Arch: is ok, accessible thru VNC, Remote Desktop, see the network, etc VM Sql : - just accessible thru VNC             - once I log in, I don't see the network             - pings don't reach peer             - appear 4 network ports on Windows the server has 4

Hi all, Has anyone seen this before? I''m running a CentOS 5.3 with xen 3.0 and the server has been running fine for a long time. In fact, it was up for 186 days before I had to reboot after the "network died", and I couldn''t fix it. The server has multiple domU''s on it, which all still works when the host node (dom0)''s network dies with these

Hello, A bit of history ================ 1) I''ve got a normal 2.6.20 x64 Fedora 6 Linux server running several things 2) I''ve downloaded and installed the XenSource Administrator Console for Windows 3) I''ve added 2.6.20-1.2962.fc6xen kernel, xen and vnc packages on my Linux server 4) I rebooted the Linux server, and started xend as per user guide Configuration

Dear Xen-Users, I use Xen 3.1.0_15042 on my OpenSuSE-10.3-computer. Without starting the xen-kernel I can connect my second computer via my native computer to the internet. After starting the xen-kernel the xen-bridge came automatically up. How can I configure the xen-bridge or the xen-devices?
