Subject Re: CS 3.0.2 does not report router system vm.
Date Fri, 22 Jun 2012 12:40:08 GMT
Hi,

  I'm starting over again with a new setup, taking into account what's
worked (and not) before.  So, things were actually ok with just NFS storage
and XenServer before.  Then I enabled local storage and added a KVM
cluster.  It completely broke everything, and by broke, I mean CS3 would
spit out blank errors all over the place, could not launch VM's, etc.  I
was pretty frustrated at that point and blew it away.  I've gotten pretty
good/quick and blowing away and re-installing CS (and all the hypervisors).
  One such issue I had previously:
http://cloudstack.org/forum/5-installation/11379-losing-all-hope-primary-storage-either-local-or-nfs-does-not-work.html
(with a link to a previous issue I had).

My new(ish) plan right now is this.  I installed ESXi, but reading the CS
docs regarding it, decided against using it.  I've now re-installed all my
hypervisors in such a manner that I shouldn't need to rely on local
storage.   Before, I had hacked XenServer to export it's local storage via
nfs.. that was problematic to say the least.  Here's my latest attempt
which I believe will now work:

1. KVM (Centos 6.2) hypervisor with 1TB local disks.  800GB exported as NFS
primary storage back for KVM use.
2. XenServer 6.02.  Primary on local lan NFS nas.
3. secondary storage on same NFS nas as a different mount.

Without enabling local storage, I think this would work, as I now realize
practically all of my issues came about when I enabled local storage.
 Disabling local storage once enabled is also not possible...

Thanks,
Alex
