[ovirt-users] Can HA Agent control NFS Mount?
Hi, I was just wondering, within the whole complexity of hosted-engine. Would it be possible for the hosted-engine ha-agent control the mount point? I'm basing this off a few people I've been talking to who have their NFS server running on the same host that the hosted-engine servers are running. Most normally also running that on top of gluster. The main motive for this, is currently if the nfs server is running on the localhost and the server goes for a clean shutdown it will hang because the nfs mount is hard mounted and as the nfs server has gone away, we're stuck at an infinite hold waiting for it to cleanly unmount (which it never will) If it's possible for instead one of the ha components to unmount this nfs mount when it shuts down, this could potentially prevent this. There are other alternatives and I know this is not the supported scenario, but just hoping to bounce a few ideas.

Re: [ovirt-users] SLA : RAM scheduling
Hi Nathanaël, You have 2 ways to get what you're after (quick/slow): 1) install 'oVirt's external scheduling proxy', and write an extremely simple weight function that orders hosts by used memory, then add that to your cluster policy. 2) open an RFE for oVirt 3.4 to have that in (https://bugzilla.redhat.com/enter_bug.cgi?product=oVirt). let me know if you consider (1), and I'll assist. anyway I suggest you'll open an RFE for 3.5.

Re: [ovirt-users] Hosted Engine - Waiting for cluster 'Default' to become operational...
Simply starting the ha-agents manually seems to bring up the VM however it doesn't come up in the chkconfig list. The next host that gets configured works fine. What steps get configured in that final stage that perhaps I could manually run rather than rerolling for a third time?

[ovirt-users] experience with AMD Kabini (Jaguar) CPUs
Hey guys, I need a system to test oVirt and Opaque on, but I want it to be super-low power and near-silent. Therefore I am thinking of grabbing one of the new 25W AMD Kabini CPUs. Will oVirt work well on that architecture? If not, what would you recommend?
