Re: Cloudstack - Monitoring

+1 for Zenoss - I¹m not directly involved like Andrew, but I did a POC a
couple years back and was impressed with features, ease of use, etc.

That is what automation is for. lol. Enabling and configuring SNMP is not a
huge task. Even on a 1000+ devices.

Re: Migration among hypervisors

[Dag Sonstebo]

Hi Mario,

you might also want to look at some of the other vendor converters -
depending on which HV you are converting to:

https://www.citrix.com/go/products/xenserver/xenserver-xenconvert-free.html
http://www.vmware.com/uk/products/converter
https://www.microsoft.com/en-gb/download/details.aspx?id=42497

Nux¹ comments still stand though - whatever migration method you use you
will have to sort HV specific drivers and tools as part of the conversion
- which sometimes involve some surgery.

Re: KVM HA is broken, let's fix it

[Özhan Rüzgar Karaman]

Hi;
This IPMI fencing is the technology where most of cloud providers like
OVirt use, so its good. How could we test this IPMI Fencing feature, where
could i find its scripts and its usage/test documents? I have some test
hardwares and i really like to try it.

Thanks
Özhan
