After done with make world and make install, I did mkinitrd and placing it in /boot changing the grub and reboot.. succeded I do not install libvirt and the domUs from the previous xen 3.0 (built-in Centos 5.2) are NOT able to start : [root@wing

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

Has anyone ran into this issue before? 2 physical nics: eth0 hooked up to 10.175.8.0/21 eth1 hooked up to 10.150.8.0/24 Ifconfig -a looks like this: [root@mgixen1 ~]# ifconfig -a eth0 Link encap:Ethernet HWaddr 00:19:B9:F2:1B:C3 inet addr:10.175.8.158 Bcast:10.175.15.255 Mask:255.255.248.0 inet6 addr: fe80::219:b9ff:fef2:1bc3/64 Scope:Link UP

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

I just did a fresh install of centos 5.0 from cd, followed by yum update which installed 399 packages. No failures or errors that I can see. I have three nics in the box, but am only setting up one at the moment. The box can ping others in my network, but if I try ssh, telnet, ftp, etc I get this: [root at cm network-scripts]# ftp watchdog ftp: connect: No route to host ftp> [root at cm

Well where do I start...I have a domU (ubuntu) booting and appears well but I don''t have an eth0 listed at all, dom) looks good.

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

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

Hi all, my dom0 is centos5.2 and domU paravirtualized is centos5.1 I can play sound on dom0 but not in domU (name: gasphar), moreover I use wifi as my inet connection and on installing domU cento5.1, I used virt-manager. I know that libvirtd made virbr0 and when changing to xenbr0, I cannot connect to internet but ssh to dom0 is fine! so how do I enable sound device on domU and changing to

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? I get routing problems: Feb 20 18:31:36 intel6550 kernel: martian source 217.237.149.142 from

Hi, I have Xen 3.0.3 installed on CentOS 5.5 with 2 paravirtualized domU''s configured to use the default bridge networking and am having networking issues. If I boot the computer fresh I am able to ping dom0 and can SSH into it and start the domU''s. The following ping snippet demonstrates the problem. The first group of "Destination Host Unreachable" is while 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

Hello, I have the following Xen 3.0.2-2 related problem: A host system with Centos 4.4 in the dom0, guest systems are Fedora Core 5 (images from jailtime.org) mounted on LVM. Networking on the domUs is not working, Iptables in the guests are not working either. Each Guest system should have at least 1 dedicated public IP assigned to it, but should have the capability to have more than 1

Hallo @all, i can ping my domU maschine from dom0, but ssh/dns between dom0 and domU dosn''t work :-( here any tests: blackhat2 = dom0 (192.168.1.1) blackhat2web = domU (192.168.1.2) (ping from dom0 to dom0) blackhat2:~# ping -c1 192.168.1.1 PING 192.168.1.1 (192.168.1.1) 56(84) bytes of data. 64 bytes from 192.168.1.1: icmp_seq=1 ttl=64 time=0.074 ms (ping dom0 to domU)

Hi, I tried this post on the Xen list first with no answer. I have 4 machines and 3 of which (all different) have no network access when booted into Xen. I tried using Fedora Core 8 and it produced the same results. Is it normal for the virbr0 interface to take an arbitrary IP? How does it decide what to use? An ifconfig when booted into Xen shows the following: eth0 Link encap:Ethernet

Hi, We''re trying to run Xen on a Debian "Etch" base system (kernel 2.6.18-6-xen-amd64), but have come across a strange networking error whenever bridging (vif-bridge/network-bridge) is in operation. The symptom is that the dom0 base system loses all network connectivity to the outside world while the two guest instances function perfectly well. As far as we can tell, we

Hi Folks: I have a strange problem with multiple (2) NICs on a CentOS 5.5 dom0 setup running xen 3.4.3 and have been struggling to fix it for some time. I could not find anything by googling or searching through this list but that is probably because I couldn''t figure out the correct search terms. After I configure my bridges the command "system network restart" fails for eth1
