I am running XenServer 6.5 and I just configured High Availability. I noticed that there is the option for start order. Is there a best practice for start order when it comes to HA?
Obviously the more important VM's should be started first, but is there any harm in having all VM's with a start order of 0?
Should I set them all in incremental order for the start order:
- VM1 - 0,
- VM2 - 1,
- VM3 - 2,
- etc.
Is it okay to have a few with start order 0, a few with 1, 2, etc.?
Also, are there any recommendations when it comes to setting the 'Attempt to start vm after xxx seconds' options?
I imagine it makes sense to have a few seconds between each VM restart but want to see what is other's opinion.
