similar to: outgoing domu network dies after a while

I have a situation very similar to whats in http://www.syslinux.org/archives/2013-January/019251.html The server is setup to provide info over dhcp+tftp and I'm planning on chaning that to dhcp+http so I copied gpxelinux.0 to pxelinux.0 and started failing. The client (in my case it's a hp proliant BL460c G7) manage to get gpxelinux.0 loaded but when it comes to load the config file it

Hello all, I have a Xen server with 6 network interfaces, I want a bridge on all of them. I use a personal network script like this : #!/bin/bash dir=$(dirname "$0") "$dir/network-bridge" "$@" vifnum=0 netdev=eth0 bridge=xenbr0 "$dir/network-bridge" "$@" vifnum=1 netdev=eth1 bridge=xenbr1 "$dir/network-bridge" "$@"

Hi Everyone, In order to prevent DomU from entering promiscuous mode, is it just a matter of adding these 2 rules when the vif is created? # Accept packets leaving the bridge going to the domU only if # the destination IP for that packet matches an authorized IPv4 # address for that domU. iptables -A FORWARD -m physdev --physdev-out vif1.0 \ --destination 216.146.46.43 -j ACCEPT

hi all , i use ubuntu 12.04 with xcp , all config run very well except vlan i use xe network-create and xe vlan-create to build vlan 3000 then startup a vm in this network, xapi0 fakebridge and vif1.0 all looks well, use ovs-vsctl list port i can see xapi0 and vif1.0 have beed taged with 3000 but i can not access the internent~~~ somebody can help me with this? thanks.

Hi, this is propably bridge related and not really a xen problem, but it might help someone: Some of our domUs are not able to arp. Arp -n show (incomplete), and doing a tcpdump shows, that on the dom0''s eth0 the arp request goes out, the response comes in, but on the vifX.0 interface the arp response is gone. dom0# tcpdump -ni eth0 arp who-has 10.32.2.51 tell 10.32.7.70 arp reply

Hello everyone, I''ve managed to configure and start Remus. However, it works only while the protected server is not loaded. As soon as I start a memory-intensive server application, the stream of Remus messages stops, leaving me with an error message. I think the message is not always the same, but here is what I''ve got from the last run: PROF: suspending at

All works fine on my virtual hosts, except the network. The internal interface is created (have an ip address), the external bridge is ok, with the external vif1.0 for the virtual host, but `ping virtual_host_address` dont work. Ok, I try to put on vif1.0 an ip address. When I do an `ifconfig vif1.0 127.1.2.3` the network works fine, `ping virtual_host_address` works and all machines from my

Hi, Creating a new domain is a lot easier in opensuse 11. I follow the instruction on the website and build a virtual machine which uses opensuse 11 as well (I installed it from iso image). Everything works fine except the network. I cannot access the Internet from DomU. Here is some information. P.S. the DomU id is 1. "brctl show" in Dom 0: bridge name bridge id STP

Hi, I have taken the long and winding road and indeed it lead me to your door. I need your help, please. My Xen includes 2 guests. Xen itself (10.2.0.52) gets free access to the outside world and to its guests. Both guests however (10.2.0.54/10.2.0.55) see each other but stay under house arrest! Not a single ping manages to go past the bridge (xenbr0) and get an answer from the default gateway

Hi Is there anyone who has successfully resolved the low throughput problem in Guest communication. I am using Xen3.4.1 with PV os kernel 2.6.30-rc6-tip On fedora11. While running netperf benchmark on guests throughput results are very low DomU to DomU    0.29 Mbps Why is it so? What would be the problem. Is there any issue with fc11 platform? Regards, Fasiha Ashraf Add whatever you love

Hi I cant start a hvm domU with more than 3 nic's configured... why? it is a bug? With previous versions it was possible... here the config - it is an opnsense (openbsd) hvm domU: name = "fenrir.chao5.int" uuid = "7aedcd03-54e8-4055-8d1b-37dd34194859" maxmem = 2048 memory = 2048 loader = '/usr/lib64/xen/boot/hvmloader' type = "hvm" vcpus = 2

It''s effectively a point to point link, allowing domain 0 to connect on to the bridge in the same manner that other domains do. (before, packets to domain 0 were short-cutted and came off the

Hello, I am having some routing troubles with my Xen setup. I have two domUs, one running as a firewall and another running as a dmz: The dom0 has the following: - eth0 bridge (10.0.0.3/24) The domU-firewall has the following: - Direct passthrough PCI NIC (Public Internet) - Virtual NIC connected to the eth0 bridge on dom0 (10.0.0.1/24) - Bridge called brdmz for the dmz zone (10.0.2.1/24)

This issue was brought up about a year and a half ago. So I''ll bring it up again and see if anything happens. I''ve got an infiniband network and am attempting to pass the infiniband card through the host and give it to the guest. I''m working with standard CentOS 5.2 on both guest and host with their provided xen (3.0.3 ish). I''ve also attempted to install the

So I might have been misinterpreting things here and might be way off base. I think you can ignore this thread and I'll follow up if I get anything concrete down the road =) The retranmissions I'm seeing and reproducing are probably within normal allowances and can't reproduce the issue that originally lead me down this path. - Nathan > -----Original Message----- > From:
