Here is a puzzle. I have a network with several servers. It''s a mess. It''s a /24 and pieces and servers are all over the place inside this /24 block, on both sides of the firewall. For example, the router at 1.2.3.1 is outside the firewall and many of the servers at 1.2.3.nnn/24 are behind the firewall. (Obviously, 1.2.3.nnn is a fudged network.) eth0 points outward to

Hi, Firstly I apologise for the cross-post, however I don't expect to get as quick a response from the package maintainers as I do from the Debian community, and this issue affects a service that I've got scheduled to go live at midnight this evening. :( A recent update from xen-hypervisor-4.1-amd64 version 4.1.3-7, to version 4.1.3-8 on Debian Wheezy has caused all vm's on this host

I have been trying to figure out why my domU NIC becomes unreachable (could not even ping) at various times. (Normally when the server was trying to update clamav from the various busy mirrors at 4am). There also seemed to be some latency when connecting which I chalked up to it being a virtual machine. When I checked my logs, I found thousands of : Nov 17 04:07:52 nomad kernel: Neighbour

I would like to customize our store-bought, bootable FreeBSD CD so that it does a non-interactive (or minimally interactive ;-) install. The interim solution we've devised has our lab execution techs booting from a CD and then using the Sysinstall "Load config file" menu option to load an "install.cfg" file from a floppy. We'd like to eliminate this step by

Hi, I have a question. I have a routeable /24 netblock including a server at a colocation and I would like to use tincd to tunnel part of that netblock to an internal network on another location being connected to the internet via gateway with DSL link and a single static IP address, so I can use public routable IP addresses on the local network. I have tincd 1.0 pre7 installed on both the local

Hello! I have two problems. One is, that I cannot ping a DomU from Dom0 (or any other host in my local network) and the second one is, that I cannot ping the same site (eg. www.suse.com) from two DomU''s at the same time. I have a fresh installation of openSuse 11.0 with Kernel 2.6.25.20-0.1-xen and my box has two physical ethernet cards. As far as I have investigated, eth0 is the one

Hello I try to customize the name of my kernel. I use the rpm source on the download page for the RHEL4.4 and I would like to differenciate the domO and the domU. cd /usr/src/redhat rpmbuild -ba SPEC/myspec.spec In the spec file I tested to change ''%define kernelvariant xen'' to ''%define kernelvariant xenHAHAHA'' or other variables with no success At the

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 all, Does any one know if this is normal operating of ARP. Or where to start looking. I am seeing a lot of ARP requests for my router IP from the same IP within seconds. 21:04:41.112929 arp who-has IP tell MY ROUTERS IP 21:04:41.186354 arp who-has IP tell MY ROUTERS IP 21:04:41.372972 arp who-has IP tell MY ROUTERS IP 21:04:41.546921 arp who-has IP tell MY ROUTERS IP

Hello all, I''ve recently observed some strange behaviour on several DomU (spread over several xen setups). While I''ve found a few reports on similar issues, the discussions were fairly old and discontinued without providing a cause or solution. Every once in a while (sometimes with an interval of several months) I get a "host down" alert for a guest host. The host is

Hi, I would like to know if somebody can point me out how to configure several DomUs in a private LAN (for example 192.168.100.0/24) and one DomU with two interfaces (one - 192.168.100.0/24 and two - internet). So far I have enabled in xend-config.sxp: (network-script network-route) (vif-script vif-route) My config files have: /mnt/VM/1.cfg:vif = [''ip=192.168.1.3'']

Dear Yalang, that did the trick. If I look in the NAT table of the bridge I can see the generated rules. Probably wouldn't have though about that ever. Thanks a lot!

Hi all. I experienced a strange behaviour in the "arp" command when I use the "pub" (publishing) flag. This is the scenario (I know it''s an unusual one, but it''s just for a test): __________ | | | host C | | | |__________| | __________|________________________________

Hello, I''m facing a rather strange problem with the netback interface. My setup involves a netvm, which has some physical network interfaces assigned, and a client VM where a net front is running (exposed as eth0) and which is connected to that netvm (via vif42.0 interface, as seen in the netvm on the dumps below). Now, the netvm has two physical network interfaces assigned: 1) A

Hi all, I''m running Xen-3.2 and linux-image-2.6.18 as Dom0 kernel on a VT-x processor. The problem is that broadcast arp who-has packets are not seen in Dom0 kernel. I''ve tried both precompiled debian kernel and compiled latest one from sources as described at http://lists.xensource.com/archives/html/xen-users/2008-01/msg00699.html There is no linux bridge invoked,
