Suggestion for configuration with only 2 nics and equallogic ISCSI
by Gianluca Cecchi 15 Mar '17

15 Mar '17

Hello, I'm going to configure an environment where I would have: - 2 x 1Gbit/s nics that I have to dedicate to ovirt mgmt network only, due to design constraints - 2 x 10Gbit/s nics where I have to configure all other VLANS In particular I have to define: 1) a couple of VLANs for VMs 2) VLAN for live migration (can I defined more that 1 of this kind?) 3) VLAN for iSCSI against an EQL system EQL guys keep saying that the only supported way to connect is through 2 different adapters and using multipath then. The iSCSI lan is on VLAN100 and I have to use it. This brings in a problem in the way I can configure logical networks in oVirt and a scenario where I create bond on top of vlan and not the reverse as I normally do.... The desiderata would be something like this, having the two 10Gbit nics the names eth2 and eth3 and vlan100 the one for iSCSI and vlan65 the one for VMs, for example: eth2 --- eth2.100 -- iSCSI IP 1 \ eth2.65 ------------------- \ __ bond65 -- IP eth3 --- eth3.100 -- iSCSI IP 2 / \ eth3.65 ------------------- Questions: - does this work at all in Linux in general? I saw something with bonding option use_carrier=1.... - in that case, can I then configure oVirt to use this configuration for networks? - is LACP supporto on switch an enabler or a stopper...? Other suggestions? Thanks in advance, Gianluca

Hello everybody, I have a 3.5.0.1-1.el6 ovirt infrastructure installed and with many ISO uploaded in my ISO storage. Is there some way to delete unusable ISOs from my ISO storage?, Many thanks in advanced, Juanjo.

oVIRT 3.5 / Virtual Machine / 10GB possible?
by Devin Acosta 15 Mar '17

15 Mar '17

We are running oVIRT 3.5, until one of vendors supports us moving to 4.0. Our RHV hosts have 20GB aggregated NICs on the box, however our VM's I notice only have 1GB NICs available. I do see that the Virtual machine is using the "virtio-net-pci" device, is there a way to get this Virtual Machine to have a 10GB NIC? When i run 'atop' on the RHV host I notice that it claims the virtual NIC is hitting 100% utilization at times. What methods do I have available to increase the 1GB NIC to something higher hopefully to 10GB ? -- Devin Acosta Red Hat Certified Architect, LinuxStack 602-354-1220 || devin(a)linuxguru.co

hosted engine without the appliance?
by Devin A. Bougie 15 Mar '17

15 Mar '17

Hi, All. Is it still possible or supported to run a hosted engine without using the oVirt Engine Appliance? In other words, to install our own OS on a VM and have it act as a hosted engine? "hosted-engine --deploy" now seems to insist on using the oVirt Engine Appliance, but if it's possible and not a mistake we'd prefer to run and manage our own OS. Thanks! Devin

Scheduled major outage for several centos services and impact on oVirt project
by Simone Tiraboschi 14 Mar '17

14 Mar '17

Hi, as announced and scheduled, several centos services are going to be out of service for about 48 hours since March 14th, 13:00 UTC: https://seven.centos.org/2017/03/infra-scheduled-major-outage-for-several-s… The list of involved services includes https://cbs.centos.org (Koji). Our stable release tracker rpm ( http://resources.ovirt.org/pub/yum-repo/ovirt-release41.rpm ) requires packages from there and so oVirt from stable release is currently not installable as well on Centos based systems. [centos-ovirt41-candidate] name=CentOS-7 - oVirt 4.1 baseurl=http://cbs.centos.org/repos/virt7-ovirt-41-candidate/$basearch/os/ gpgcheck=0 enabled=1 [centos-ovirt-common-candidate] name=CentOS-7 - oVirt common baseurl= http://cbs.centos.org/repos/virt7-ovirt-common-candidate/$basearch/os/ gpgcheck=0 enabled=1 We are trying to find a recovery solution.

oVirt 4 and 10GbE NICs
by Davide Ferrari 14 Mar '17

14 Mar '17

Hello the oVirt hosts in my cluster have all 10GbE interfaces (bonded 2 by 2), and I was wondering if a single Linux VM with a virtio interface can reach for example 8Gbps. I'm asking because I'm seeing a 100% network usage in some VMs in ovirt VM dashboard but the real traffic in that VM is between 1-2Gbps. Thanks -- Davide Ferrari Senior Systems Engineer

Hello! Thanks - try to remember put cc More information: Our server has separated management Network interfaces (nic) - in HP server i use ILO web managem interface to access server remote console. (HP iLO Integrated Remote Console) I used this renote console to access this freezed node and i was no abel to ping or access ohter host in the same network. Then open this remote console i saw many "vcpu unhandled rdmsr" messages. My node had GbE nic interface with ip address that was not used by ovirtmagmt interface. I was no tabel ping or access this interfiace then node freezed.

After that i was no tabel to Access node over ssh Whole node freezed. Only after reboot i was abel to access thise host again over ssh. You said you saw something on the console. I thought you meant you managed to login. If you didn't, then indeed the problem wasn't (probably) only in networking, but something deeper, in the kernel probably.

iscsi data domain when engine is down
by Devin A. Bougie 14 Mar '17

14 Mar '17

We have an ovirt 4.1 cluster with an iSCSI data domain. If I shut down the entire cluster and just boot the hosts, none of the hosts login to their iSCSI sessions until the engine comes up. Without logging into the sessions, sanlock doesn't obtain any leases and obviously none of the VMs start. I'm sure there's something I'm missing, as it looks like it should be possible to run a hosted engine on a cluster using an iSCSI data domain. Any pointers or suggestions would be greatly appreciated. Many thanks, Devin
