How To Enable Networking In Xen Guests On Hetzner's DS Servers (Debian Etch)

Sun, 15 Nov 2009 18:35:26 +0100

How To Enable Networking In Xen Guests On Hetzner's DS Servers (Debian Etch)

This tutorial shows how you can enable networking in Xen guests (domU) on Hetzner's DS servers. With the DS servers, you can get a subnet of eight additional IPs (or more) - usually that subnet is different from the subnet that the server's main IP is from. The problem is that these additional IPs are bound to the MAC address of the host system (dom0) - Hetzner's routers will dump IP packets if they come from an unknown MAC address. This means we cannot use Xen's bridged mode, but must switch to Xen's routed mode where the host system (dom0) acts as the gateway for the guests.

How To Enable Networking In Xen Guests On Hetzner's New EQ Servers (Debian Lenny)

This tutorial shows how you can enable networking in Xen guests (domU) on Hetzner's new EQ servers. With the new EQ servers, you can get up to three additional IPs that are in the same subnet as the server's main IP. The problem is that these additional IPs are bound to the MAC address of the host system (dom0) - Hetzner's routers will dump IP packets if they come from an unknown MAC address. This means we cannot use Xen's bridged mode, but must switch to Xen's routed mode where the host system (dom0) acts as the gateway for the guests.

Installation And Setup Guide For DRBD, OpenAIS, Pacemaker + Xen On OpenSUSE 11.1

Mon, 17 Aug 2009 19:48:34 +0200

Installation And Setup Guide For DRBD, OpenAIS, Pacemaker + Xen On OpenSUSE 11.1

The following will install and configure DRBD, OpenAIS, Pacemaker and Xen on OpenSUSE 11.1 to provide highly-available virtual machines. This setup does not utilize Xen's live migration capabilities. Instead, VMs will be started on the secondary node as soon as failure of the primary is detected. Xen virtual disk images are replicated between nodes using DRBD and all services on the cluster will be managed by OpenAIS and Pacemaker. The following setup utilizes DRBD 8.3.2 and Pacemaker 1.0.4. It is important to note that DRBD 8.3.2 has come a long way since previous versions in terms of compatibility with Pacemaker. In particular, a new DRBD OCF resource agent script and new DRBD-level resource fencing features. This configuration will not work with older releases of DRBD.
