James -
TX so much for your reply. I had done some research into ganeti, but
hadn't see that presentation - I found it very helpful.
I have posted some questions to a ganeti group, because first &
foremost, I don't want to move my VM's out of vmware. So I would need
vmware to run on the 'ganeti system', and don't know if that can
happen, or if it makes sense to do it that way...
Also - as you've already indicated, ganeti seems to want a 3rd pc to
manage everything. In the future, this may start to make more sense,
but for now, I really want a 2-pc solution.
For me, it's not necessary to have a dual-homed system after 1
failure. It's simply enough to have 1 fully running system. I'd like
the VM's to continue without reboot if 1 fails, but if the 2nd system
should fail during the downtime of the 1st failed system, I can live
with that. (for now ;-)
Would you happen to be able to address any of those questions?
TIA - Bob
