Bringing the VMs back online
okay. New hypervisor hardware. Switching from xen to KVM. I took a snapshot of the xen partitions and moved them to a holding location during migration. I am now imaging these partitions to the LVM block devices: calcifer:/home/cjac# for guest in `ls /usr/src/moonunit-guests/ | grep -v -e etc | awk -F- ‘{print $1}’` ; do […]

This is getting serious.
I might have to visit the HP on which I recently upgraded the iLO firmware… Maybe it would be good if the family visited Seattle. cjac@foxtrot:~$ ps auwx | grep ‘ping ad0.colliertech.o’ cjac 8411 0.0 0.0 10692 920 pts/8 S+ Apr25 0:32 ping ad0.colliertech.org cjac@foxtrot:~$ ping ad0.colliertech.org PING ad0.colliertech.org (208.115.126.68) 56(84) bytes of data. 64 […]

AD Physical to Virtual conversion… Continued!
So I wasn’t able to complete the earlier attempt to boot the VM. Something to do with the SATA backplane not having enough juice to keep both my 6-disk array and the w2k8 disk online at the same time. I had to dd the contents off of the w2k8 disk and send it to the […]

Ohai! It looks like I’m back online!
I’m working on my disk array today. The plan is to take the data off of a 6-disk RAID-6 and put it onto three 4-disk RAID-4s.

AoE root for KVM guests
Intro So. I’m trying to get familiar with libvirt and friends. To this end, I’ve set up a Lucid virtual machine booting from PXE into an initrd environment which does a pivot_root to an AoE block device. The #virt channel on irc.oftc.net told me that in order to have libvirt provide PXE capability, I would […]

Sorry for the downtime
One of my servers (and co-incidentally, the one on which this blog is hosted) was down for the last week. I ran out of space on / and created a new lv to store the contents of /usr. I named the lv dom0-usr but referred to it as amd0-usr in /etc/fstab. It didn’t boot so […]
