similar to: please help with xen networking with 2 ips

Hi, the networking just drives me crazy and it seems that i am missing something. So here is my situation: i have a server with 2 public IPs (85.214.1.230 and 81.169.1.81) the dom0 is on: ip 81.169.1.81 netmask 255.255.255.255 gw 81.169.1.1 i would like to have a domU with ip 85.214.1.230. I tried everything routing, bridging.. nothing seems to work. my dom0 config; . (network-script

Hello, i see a strange behavior with timestamps of files on a samba share (4.2.6 on SLES 12 SP1 and 4.1.8 on Ubuntu 14.04) with "dos filetime resolution = yes": On older samba versions, windows properties dialogue correctly shows only even seconds, but (at least) the two indicated versions show sometimes even and sometimes odd seconds if the file has on the server filesystem a

Hello, I want to setup dovecot with two postfix servers on three machines: - dovecot - with huge amount of disk space - where all user emails will be kept, - postfix1 - with greylisting, amavisd-new (spamassassin, clamav, etc), with mysql backend, - postfix2 - same as postfix1. MX priority will be set to the same value for both postfix machines. For now I don't know how to "glue"

Hopefully I summed up the jist of the problem in the subject line. ;) I have a GFS cluster with ten Xen 3.0 dom0s sharing an iSCSI LUN. There are on average 8 domUs running on each Xen server. The dom0 on each server is hard-coded to 2 CPUs and 2GB of RAM with no ballooning, and has 2GB of partition-based swap. When creating a new domU on any of the Xen servers, just after the completion of

I present you with a function that solves a problem that has bugged me for many years. I think the problem may be general enough to at least consider adding this function, or a revamped version of it, to the 'stats' package, with the other multinomial functions reside. I'm using R to export data to text files, which are input data for an external model written in C++. Parts of the

Today I found I can not ping some of my domU''s. I logged in to dom0, did a "xm list", all domU are there. Then I did a "ifconfig" and surprised to find some of vif''s disappeared! Like for example. "xm list" show dom13 is alive, but "brctl show" shows no vif13.0. If I "xm console 13", there''s some message: WARNING:

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

Raffaele If you don't want to see much arp traffic on eth1, assuming that you have a subnet 10.190.190.0/24, with 10.190.190.1 on eth1 and the rest of the hosts on eth0, you can use for example, the following filter ebtables -N f1 ebtables -P f1 DROP ebtables -t filter -A FORWARD -i eth0 -o eth1 -p ARP -j f1 ebtables -t filter -A f1 -p ARP --arp-ip-src 10.190.190.0/24 --arp-ip-dst

Hi, I tried already a long time to enable network in my domU but I always fail with: # ifconfig eth0 192.168.0.1 up SIOCSIFADDR: No such device SIOCGIFFLAGS: No such device Do I need to load a kernel module? I use OpenSuse 10.2 with kernel 2.6.18.8-0.5-xen (for both domU and dom0). My config: kernel = "/boot/vmlinuz-xen" ramdisk = "/home/jens/initrd.gz" memory = 1024 name

Hi, there: I have installed xen(2.6.18.8-xen) and had successfully started domU guests (one or two) from dom0. However, I am not able to start the network for domU machines. Following is the information from my linux box. After the it is started: $ ifconfig eth1 Link encap:Ethernet HWaddr 00:A0:C9:D6:65:DB inet addr:XXX.XXX.10.133 Bcast:XXX.XXX.10.255 Mask:255.255.255.0
