Ovirt and power saving
by Mario Giammarco 18 Jan '15

18 Jan '15

Hello, I would like to ask if it is possible to do this use case with ovirt: 1) two servers powered on 2) operator suspend some virtual machines 3) load falls down 4) ovirt shutdown one server Then operator unpauses virtual machines and ovirt starts again the 2nd server. Thanks, Mario

Put the engine inside hosts after installation
by Mario Giammarco 18 Jan '15

18 Jan '15

Hello, I would like to try ovirt with hosted engine installation. I had so many problems (I have written them in another thread) so I will not try anymore hosted installation (up and running with ovirt 3.5 tutorial) But now I would try this approach: I install the engine on a dedicated server or as a virtual machine in another kvm based virtualizator. Now I create an ovirt cluster and use it. Can I after that install change my mind and so move the engine as a vm in the cluster? Or can I install a new engine in the cluster and powerdown the first engine? Thanks in advance for help, Mario

Low cost fencing/stonith devices
by Mario Giammarco 16 Jan '15

16 Jan '15

Hello, I ask this question again to see if there are some improvements. I am searching for a low cost stonith/fencing device for servers or hardware that has no ipmi/ilo on board. I see that there are some interesting products on the market like ubnt/mfi mpower that are controllable power outlets but there is no driver for them. In my use case WOL support will be enough (using it with ssh or shared storage fencing) but as far as I know WOL is not yet supported in ovirt. So is there some fencing device supported in 100/200$ price range? Thanks, Mario

Use dedicated I/O service domain in KVM
by Yidao Liu 16 Jan '15

16 Jan '15

Hi, I want to use a dedicated guest VM to handle I/O request just as I/O service domain used in xen. Specifically, using network I/O as an example, I should directly assign the NIC to one guest VM (using pci-assign option), after that all other guest VMs should perform network I/O through that VM rather than the host OS. Is there currently any viable approach to do this? If not, I want to implement one. Currently I'm thinking of combining nahanni shared memory and vhost architecture to implement it, is there any other suggestions? Thanks for any help.

Re: [ovirt-users] Performance issue for GlusterFS as the block storage for VMs

--_000_ED08B56256B38842A463A2A0804C5AC0326B0A4595svrcaexch1atg_ Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: quoted-printable Hi I have one question about whether GlusterFS is the suitable solution to be = used as the block storage for VMs. The failure tolerant and scalability is good for GlusterFS, but in my test,= it seems the iops is pretty bad. In some blog, it said, it is even with wo= rse performance than normal NFS. Should I use iscsi+drbd for the block storage for VMs. Can somebody give some advice for this?
