delete snapshots or create a template make a huge impact on VMs on SPM-node
by Ricky Schneberger 15 Oct '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, When we do some tasks in ovirt as delete an snapshot or clone a machine or just want to make a machine template the impact on VMs residing on the SPM node is huge. Is there a way to prevent this? This is just normal tasks and we do this all the time. - -- Ricky Schneberger - ------------------------------------ DANGER!

Re: [ovirt-users] ovirt network VLAN tagging
by Juan Pablo Lorier 15 Oct '14

15 Oct '14

Hi, It seems to me that it may be a switch configuration problem. The vms in the same host can talk to each other via the bridge, but if your switch is not configured to allow tagged traffic for vlans 50 and 60 (and all the way to the interface of the other host must allow tagged traffic for those vlans), you won't be able to get traffic. Regards,

async vm start (python)
by Giulio Casella 15 Oct '14

15 Oct '14

Hi everybody, I'm trying to start a VM (using python sdk) asynchronously, but I obtain synchronous behaviour. The engine is RHEV-M version 3.4.1-0.31.el6ev. Here a snippet of code: --------------------------------------------------------- myvm = api.vms.get(name="VMNAME") retval = myvm.start(params.Action(async=True)) print ParseHelper.toXml(retval) --------------------------------------------------------- and this is what I get (retval): --------------------------------------------------------- <action> <async>true</async> <vm href="/api/vms/5aa66e96-5fdd-4562-9c7d-ae6f88e6805d" id="5aa66e96-5fdd-4562-9c7d-ae6f88e6805d"> [...cut..] </vm> <job href="/api/jobs/5c2326c7-f25c-432f-8848-c94e80dd173b" id="5c2326c7-f25c-432f-8848-c94e80dd173b"/> <status> <state>complete</state> </status> </action> --------------------------------------------------------- status of task is always "complete" and the operation take some time, few seconds to some tens of seconds (sync behaviour). Any ideas? Thanks in advance, Giulio

Hi friends! I have just upgraded from 3.2 to 3.4 and it was very nice. Everything ok! Now I want to enable Gluster Service to my cluster in production. I think follow this steps: * Install manually vdsm-gluster * Restart supervdsm and vdsmd * Enable Gluster Service in my Cluster. Could it cause any problem or downtime? Thanks.

Vlans and subnets
by Demeter Tibor 14 Oct '14

------=_Part_650053_579042154.1413309486419 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 7bit Hello all, I've created a self-hosted ovirt engine with two node, but on the last steps the engine-setup could not attach the node to the "default" cluster. I think it was because I have different services on different vlans. I have vlan100 for glusterfs and vlan101 for vdsm hosts with different subnets. Also, I have an another connection (eth1) with different subnet for internet acces and this is the default route. I would like to separate ovirt services, networks and glusterfs to different vlans/subnets by security reasons. But I don't know what services need to be on same vlan/subnets. My questions/goals - which services need to connect to another ? - Is hosted engine's vm need to be on same network with gluster ? - Is hosted engine's vm need to be on same network with vdsm hosts? - I want to separate ovirt/gluster networks from ovirt VM-s/public internet access - I don't want to extra traffic on router Does anyone experience with this way?

Packet loss
by Kyle Gordon 14 Oct '14

14 Oct '14

Evening all, I'm having major issues with a self hosted setup (oVirt 3.4.4 & CentOS 6.5) on Hetzner, with 2 subnets allocated to the server. Routing to and from the additional IP ranges is working as expected, and I can allocate any of the IPs to a virtual interface on the host and get connectivity, so from what I can tell the network routing side of things is correct. However, when I move any of the allocated IPs to any of the guests, I get 1 ICMP response before complete packet loss. This happens at all times, even with iptables completely unloaded and an Accept policy thoughout. The structure is just a basic bridge called ovirtmgmt that all interfaces are bound to. Guests that are affected can communicate with other guests on either of the two subnets, and also with the host, so the bridge is up and running, but when it comes to any traffic trying to egress by the default route, it comes to a halt. In addition, all the hosts have unique MACs, dmesg shows that the appropriate vnets are entering forwarding states and STP is disabled on the bridge. And just to confuse matters, one guest is working just fine - yet when the settings are replicated to any other host the new host still fails to work. Even if I put the working IP onto another guest, it fails to transfer any data. All I get is constant who-has requests on the host bridge whilst the guest looks for the next-hop. Has anyone experienced this before? Where's next on the list of places to look?! Regards Kyle -- Kyle Gordon - 2M1DIQ Web: http://lodge.glasgownet.com Jabber/Email/SIP: kyle(a)lodge.glasgownet.com

ISO_DOMAIN as iscsi storage type
by ml ml 14 Oct '14

14 Oct '14

Hello List, i am very unhappy with NFS for my ISO_DOMAIN domain. Can i simply remove my ISO_DOMAIN via NFS and add a ISO_DOMAIN via isci? My Setup: http://oi60.tinypic.com/2cmu7nm.jpg I once ran into a pitfall where i was not able to add a ISO DOMAIN anymore, so i would rather ask in advance if i can remove the ISO_DOMAIN and simply add it again via iscsi. Do i need to take care of anything here? Thanks, Mario

[Request for Mentors] oVirt Outreach Program for Women
by Brian Proffitt 14 Oct '14

14 Oct '14

All: Since my Sept. 19 request for mentors for the GNOME OPW project[1], I have had no responses from anyone to lend an effort on mentoring potential applicants. The application process has been opened and I know we have had at least one potential candidate[2] interested, and I would hate to turn people away because we did not have mentor(s) to assist them. The application deadline for OPW is Oct. 22, but because potential applicants are required to get involved with the community before they formally apply, it is very important we have some mentors in place as soon as possible. oVirt has an excellent community in place, and here's another chance to show that off! Peace, Brian [1] http://lists.ovirt.org/pipermail/devel/2014-September/008829.html [2] http://lists.ovirt.org/pipermail/devel/2014-September/008896.html -- Brian Proffitt Community Liaison oVirt Open Source and Standards, Red Hat - http://community.redhat.com Phone: +1 574 383 9BKP IRC: bkp @ OFTC
