anyone out there using arch + kvm in production? i'm looking at 30+ blades and i need to get a decent number of Server 2008 instances from all of those blades. i'm not looking to pool all the resources into some sort of private cloud. rather i just want to have 3-5 instances of Server 2k8 (i need IIS 7) per blade. here are few things that i'm interested it:
1. if you do run this setup how often do you pacman -Syu your arch boxes?
2. how often does the upgrade break something (kvm)?
3. what do you use to monitor the hosts and guests?
4. any other hints/suggestions/ etc.
i only run arch in production on my monitoring servers but i can also afford to be without those for an hour or two while i fix whatever the update/new config broke. any comments on arch in production are welcomed.

For a lot of KVM machines, I would rather suggest to go with Fedora 16/centos6/rhel6... In arch you'll have to administer each VM independently and/or compile necessary tools like libvirt, etc.
Arch Linux is more than just GNU/Linux -- it's an adventure
pkill -9 systemd

1. if you do run this setup how often do you pacman -Syu your arch boxes?
Not as often as I planned, which was once a month
2. how often does the upgrade break something (kvm)?
Once an old unsupported os broke with a kvm update
3. what do you use to monitor the hosts and guests?
Zabbix
4. any other hints/suggestions/ etc.
I don't have that many servers, I keep a testing server with the sum of all applications on it and test the upgrade process on that one first. On critical servers I swap in the test server while upgrading the original.
Unfortunately I had one server crash without a trace of the cause. It can be some hardware problem though.
