Moving Hosted Engine Disk
by Charles Kozler 09 Sep '16

09 Sep '16

Hi - I followed this doc successfully https://www.ovirt.org/documentation/how-to/hosted-engine/ with no real issues In oVirt I have the hosted_storage storage domain and the one I created (Datastore_VM_NFS) to be a master domain - this is all fine My hosted_storage domain is on a SAN that is being deprecated. I am wondering what I need to do to **move** the disks for Hosted Engine VM off of that storage domain and on to another one. I can create a new volume on the new SAN where the VMs are stored but from all that I have found it doesnt look like I can actually move the hosted engines disks with out possibly rerunning the entire hosted-engine --deploy but I am not sure if this will cause any other conflicting problems Thanks

BSD Guests + oVirt
by Hanson 09 Sep '16

09 Sep '16

Hi Guys, Is there any optimizations for using FreeBSD 10.3 with ovirt? The guest OS works fine, however, the engine frequently lists the wrong status for the VM, like rebooting, booting etc. ovirt-guest-tools doesn't support freebsd from what I can find. Thanks!

--=_3818970e-fa47-4701-bb0f-ddac43ad927f Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 7bit Hi, In my server I have 4 nics I was thinking about using NIC3 and 4 for starage (ISCSI or NFS) Two (NIC1 and 2) For management and VM traffic using VLAN. But when I installed Ovirt, I had to use the firts NIC without Vlan. Native vlan did not work. So at the switch the NIC1 and 2 are in mode access. After deploying hosted-engine the ovirtmgmt network was create on first NIC. If I want redundancy I would have to add nic 2 to ovirtmgmt . And there is no more NICS for the VMs. Are there a way to configure VLAn on ovirtmgmt, moving hosted-engine to a VLAN? Any idea?

Ovirt with bad IO performance

Hi i am trying Ovirt 4.0 and i am getting some strange results when comparing with Xenserver **The host machine* Intel Core i5-4440 3.10GHz running at 3093 MHz 8 Gb of RAM (1x8) 500 Gb of Disk (seagate st500dm002 7200rpm) CentOS 7 (netinstall for the most updated and stable packages) **How i am testing:* I choose two benchmark tools, sysbench(epel-repo on centos) and novabench(for windows guest, https://novabench.com ), then i make a clean install of xenserver and create two guests(CentOS and Windows 7 SP1) **The Guest specs* 2 cores 4 Gb of RAM 60 Gb of disk (using virtIO in a NFS storage) Important note: only the testing guest are up on benchmark and i have installed the drivers in guest **The Sysbench disk test(creates 10Gb of data and do the bench):* # sysbench --test=fileio --file-total-size=10G prepare # sysbench --test=fileio --file-total-size=10G --file-test-mode=rndrw --init-rng=on --max-time=300 --max-requests=0 run Host result: 2.9843Mb/sec Ovirt result: 1.1561Mb/sec Xenserver result: 2.9006Mb/sec **The novabench test:* Ovirt result: 79Mb/s Xenserver result: 101Mb/s I do other tests, like cpu, memory and etc, ovirt wins with a small advantage(less then 1%) Adicional info: i use this command to install ovirt repo yum install http://resources.ovirt.org/pub/yum-repo/ovirt-release40.rpm i follow this steps on installation: http://jensd.be/550/linux/install-ovirt-on-centos-7
