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…

Relatively high sustained rates detected along I-405
$ scp moonunit.colliertech.org:/mnt/downloads/sh1-disk-20140420T070034.xz . cjac@moonunit.colliertech.org’s password: sh1-disk-20140420T070034.xz 76% 534MB 11.1MB/s 00:14 ETA Come on little internet! You can do it! You can push 100Mbit! I remember when this was the fastest I could send data across my LAN. Not bad for a 20 mile shot up I-405. Sorry if I caused any congestion there, folks.…

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…

Windows is *still* loading files
I’m moving the active directory server off of hardware on to the hypervisor. I think if I boot the drive as USB I can install the virtio disk drivers on the system. Fingers crossed! Only thing is that this first boot off of a USB device takes *sooooo* long!

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.

UW Hypervisor looks stable
The new hardware looks like it’s reliable. The one I swapped out 10 days ago crashed every 3 days or so for reasons I couldn’t discern. I changed that one for a spare I had laying around and have been hosting my blog on the machine to exercise it. So far, no crashes, and a…

Migrating VMs from pure paravirt hypervisor to hvm-capable hypervisor
I’m also changing all of my disk layouts from being block devices per each guest partition to one block device hypervisor side per each /dev/xvd* guest side. The block devices all live on a single storage server and are being served via iSCSI. One of the guests is making use of AoE, but I’m thinking…
