Native gluster without FUSE
by J. Mikulec 22 Sep '14

22 Sep '14

Hello, at http://www.ovirt.org/Features/GlusterFS_Storage_Domain I can read oVirt allows glusterfs domains which maps to <disk type=network..>...</disk> in libvirt xml without USE overhead. My oVirt still creates and uses mount for disks at qemu as -drive file=/rhev/data-center/mnt/glusterSD.... Is possible to use GlusterFS storage domain without FUSE? Fedora 19, oVirt 3.4 (Centos 7 the same) Thanks! Jiri

Admin console - Always show advanced options
by John Gardeniers 20 Sep '14

20 Sep '14

Hi All, When viewing/editing a VM's properties in the admin console is it possible to show the advanced options by default? Quite frankly, I can't understand why that isn't the default. The standard options show nothing that isn't already visible in the properties window in the console, so what's the point of making that the default in the editing window? Regards, John

User permissions for user portal
by J. Mikulec 20 Sep '14

20 Sep '14

Hello, I can't figure out right user permissions. I can add user which can do just this through user portal: - see and change status of VM (including Power Off) - remote console - change CD (+ maybe os type) Change status and console (without power off) comes with UserRole, power off and change CD comes with UserVmManager. But UserVmManager brigns also wide options to manage network interfaces, disks etc, what is unsafe for me to delegate it to this user. Thanks, J.M.

Sealing a CentOS-7 Guest as a oVirt Template

Previously on CentOS-6 I used "sys-unconfig" or "touch /.unconfigured", but this is on CentOS-7 no longer possible. I can use on CentOS-7 the "nmtui" after the OS is loaded, but maybe someone knows a way to run it during the boot sequence.

OVIRT-3.5-TEST-DAY-3: CPU SLA for capping
by Martin Perina 19 Sep '14

19 Sep '14

Hi, I tested the support to limit CPU utilization of hosts. Setting it up in the GUI worked correctly, but for running VM settings are ignored. I used XMLRPC protocol to avoid [1]. To simulate VM CPU utilization I used stress tool [2]. Testing steps: 1. Create a VM with the same number of CPUs as Host 2. Create CPU type QoS in DC and set the limit to desired value 3. In Cluster create new CPU profile with above QoS and remove the default CPU profile 4. Start the VM and execute (N is a number of CPUs in VM) stress --cpu N 5. Connect to Host and execute sar -u 1 10 No matter what the limit was set to (1, 50, 100), host CPUs were always utilized to 100%. So I create bug to cover this [3].

[Speaking Opportunity] Central PA Open Source Conference 2014
by Brian Proffitt 19 Sep '14

19 Sep '14

If anyone in the eastern Pennsylvania/New Jersey area is interested, the oVirt community has been personally invited to have a speaker attend CPOSC on Nov. 1 in Lancaster, PA. Unfortunately I cannot attend, as I will be traveling that day. But this is a great opportunity to speak to a green-field audience about oVirt and what it can do. If you would like to give a talk about your favorite datacenter management platform, visit the CFP page at http://www.cposc.org/ and post a proposal. (Ignore the Sept. 10 deadline; oVirt is assured a slot.) If you do want to present, we can send you presentation materials to use for an overview talk, so let me know! Peace, Brian -- Brian Proffitt Community Liason oVirt Open Source and Standards, Red Hat - http://community.redhat.com Phone: +1 574 383 9BKP IRC: bkp @ OFTC
