XEN 3.4 with ipv6 routing

Yes, there are a few postings out there about getting ipv6 routing running with XEN. But I’ll throw this online anyway since there are a few changes I had to make for it to work on my server. This text is intended for people who know their way around Linux and XEN so it will be a bit technical and won’t spell out every single step you have to make. Most of the changes are based off scripts and information from BenV and wnagele (latter is interesting for me since I am also running XEN on a hetzner server). Have a look at the two links if anything is unclear. […]

back online

The hard drive crash threw me offline a few days due to strange problems with software raids, Xen and acpi. Turns out that using the latest Xen kernel from debian testing branch on a software raid only works of you don’t set “acpi=off” as a kernel parameter. If acpi is turned off, the script “scripts/local-top/mdadm” in the initrd can’t find the devices needed to mount the software raid … causing the whole boot process to come to a grinding halt. If I find some time I’ll do some more tests, untill then my server will be running with acpi turned on btw. the hard disk replacement was easy. after the […]

XEN and Kernel update

Server is up and running again. This morning I finished the xen (3.4) and kernel (2.6.32) updates I prepared yesterday evening. The only pitfall I stumbled across, was that the kernel in the debian repository (2.6.26-xen) seemingly wasn’t compatible with the latest xen in the debian repository (system would hang while booting, I guess that’s what I get for using “testing”). Here are a few tips to make the transition a breeze ….

Serverdown

Server was down for the last 6 hours due to me updating a few stuff that really really didn’t work out too well (grub, xen and kernel at the same time). I gave up and afer a few hours of work managed to revert back to the old configuration so I can recieve mail again till I figure out what went wrong. Server may be down tomorrow a bit too while I try to figure out what exactly broke and try to at least get grub and xen updated.
