Hi, I''ve installed xen 3.0.3 from packages (xen-linux-system) on a debian etch, and i''ve configured it with network-bridge script in the default way (netdev=eth0, bridge=xenbr0, etc...) which is ok for me. the problem I have: I cannot ping any outer machine from dom0 (nor any outer machine can ping me). It gives me a "Destination Host Unreachable" message that

I'm looking into some network "weirdness", and I noticed that a CentOS 6 system with multiple IP addresses (load balancer running keepalived) is sending ARP requests from apparently random source IPs. I would have thought that ARP requests would always come from the interface's "primary" IP (especially since keepalived adds all the virtual IPs with a /32 mask). This

Okay, so I''m trying to setup my multiple ISP setup that I described earlier. I have: # ip addr 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: em1: <BROADCAST,MULTICAST,UP,LOWER_UP>

Hi All, Having an issue with xen-4.0-unstable where after completing a live migration, an arp is never sent out to update the switch with the new location of the mac address. Network is configured as per libvirt''s instructions with the xen network-script disabled and the bridge (xenbr0) always up.

I am having a problem compiling R on an HP-UX 10.20 system using gcc/g77 compiler.

Hello, I''ve read the FAQ and searched the mailing list but have been unable to resolve my issue with networking in DomUs. The following things I CAN do: +SSH from within DomU to Dom0 +SSH from within DomU to all other DomUs on the same machine +SSH to other machines from within Dom0 +SSH from within DomU to other machines +SSH from other machines to Dom0 (and use the xm commands to

Hi, For my experiment on live migration of Xen VMs, I want the MAC address of the migrated VM (domU) to change soon after migration, but just before the Gratuitous ARP reply is sent. Do you know where in the code/scripts I can add this feature? Thanks, Vikram _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com

Hi Laine What you have suggested sounds eminently reasonable. Thanks for your advice. I'm going to give it a shot and report back.

Hi all, I''m searching for a tutorial how to setup multiple network cards with xen network bridge setup in debian lenny. My problem is, bridges seams only to work if i put an ip adress in dom0 to them.

Basically I''m not using a network script from xen. I define a

Hi list. I started with Xen yesterday, but I am facing a bit of a problem. My system had always configure eth0 with 10.0.0.4/8 I am using Xen unstable source (on Debian sid) Now I installed Xen, rebooted the machine, and first the usual network is coming up and then the xend will be started. I''ll end up with this, but I am wondering if this should be the way of things to be

Hi, I have spent a fair amount of time trying to solve this problem and tried things like disabling checksums etc. The problem is like this: 1. I boot my dom0 without xend running and I can resolve and ping google. 2. I start xend (without and domU domains up) and after a while I can no longer resolve domain names, but I can ping the public IP addresses. 3. I start up a domU (xm create -c xyz)

Even more puzzling, I reverted back to the old configuration to confirm what I had seen and found that it works in one direction but not the other: i.e. from 192.168.0.110 to 192.168.0.120, but not the other way around. Must be something with my configuration....which I can follow up on. So, thanks again for your help. Richard On 12/3/19 11:36 AM, Richard Achmatowicz wrote: > Laine >
