Hi All
Thomas Ellerman , Kathleen Wilsen , Karsten Nielsen and John Clark have written a book for Microsoft Press and edition by Mitch Tulloch
Microsoft System Center: Optimizing Service Manager
Its a free ebook so just in time for a early xmas gift for all your friends 🙂
http://shop.oreilly.com/product/0790145396716.do , the book is out in print for about 2 cups of coffee
Aidan Finn pointed out in a recent post that there are changes in 2012 R2 Backup of Virtual Machines
http://www.aidanfinn.com/?p=15759 , as always its a good read
One change is that we rely on snapshots on the virtual machine what this looks like from a backup point of view
Create the Backup Job
Start the Backup
We can now see that a snapshot is being created will redirect write IO to the avhdx files
We can see the avhdx files created when the backup starts
And after the backup is complete the snapshot is being merged
Creating a additional backup
Repeats the pattern , shapshot backup cleanup
For recovery we can see the snapshots created during backup and a full recovery restores both vhdx and the xvhdx file
DPM == Sucess
And when we start the recovered VM it merges the delta files , and we can start the VM again
VM was consistent and didnt show any unexepted shutdown error when restarted
We ran into a issue that was resolved with our good friends from Microsoft , (thanks Michael and Tomas)

As soon as we went beyond the first numa node memory config we had a kernel panic
PANIC: Early exception 06 rip 10:ffffffff81c451bb error 0 cr2 0″
Long story short if you suck as much using VI as i do then DONT 🙂
Stick to the GUI instead , and leave the Linux for others
Hint to find this
[[email protected] ~]# cat /proc/cmdline
ro root=/dev/sda1 rhgb quiet numa=off
When we first booted after we thought we edited the setting we couldnt see numa=off at boot
So back to GUI for me at least
go to /etc/grub.conf
add numa=off on the kernel boot parameter
shutdown
add memory to span numa nodes
and reboot
and sucess
Oracle Enterprise Linux 6.4 running in Hyper-V spanning numa nodes on memory
