Network Interface order changed after reboot

Hi List, I have two nodes (running CentOS 7) and the network interface order changed for some interfaces after every reboot. The configurations are done through the oVirt GUI. So the ifcfg-ethX scripts are configured automatically by VDSM. Is there any option to get this configured to be stable? Best regards and thank you Christoph

InClusterUpgrade Scheduling Policy
by Scott 27 Jun '16

27 Jun '16

Hello list, I'm trying to upgrade a self-hosted engine RHEV environment running 3.5/el6 to 3.6/el7. I'm following the process outlined in these two documents: https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Virtualiza… https://access.redhat.com/solutions/2300331 The problem I'm having is I don't seem to be able to apply the "InClusterUpgrade" policy (procedure 5.5, step 4). I get the following error: Can not start cluster upgrade mode, see below for details: VM HostedEngine with id 5ca9cb38-82e5-4eea-8ff6-e2bc33598211 is configured to be not migratable. But the HostedEngine VM is not one I can edit due to being mid-upgrade. And even if I could, the setting its complaining about can't be managed by the engine (I tried in another RHEV instance). Is this a bug? What am I missing to be able to move on? As it seems now, the InClusterUpgrade scheduling policy is useless and can't actually be used. Thanks for any suggestions/help, Scott

oVirt 3.6 to 4.0 Upgrade
by Brett I. Holcomb 27 Jun '16

27 Jun '16

In order to not hijack another thread I wanted to separate this from the "latest CentOS libvirt updates safe?" thread since this is different than what the OP on that thread wants to do. I've been digging through the 4.0 documentation since I'd like to upgrade in the not to distant future so I'm doing research and I'm confused. I'm running 3.6.6 in a hosted Engine environment. My engine runs in a vm on the host. The host is a physical box and the VMs are stored on a NAS accessed by an iSCSI LUN, I have no other hosts running so I can not migrate. According to this link, https://www.ovirt.org/release/4.0.0/, I'm told to simply run yum update ovirt-engine-setup and then engine-setup but I assume that's for a non hosted-engine environment. I then go to the link for Hosted_Engine_HOwto#Upgrade_Hosted_Engine guide and am told to do this. Set hosted-engine maintenance mode to global and other stuff that is written assuming I have some place to migrate my VMs to. I do not have another host. So how do I properly move to oVirt 4.0 from 3.6.6 on a single physical host running a hosted Engine VM? Thanks.

oVirt/RHEV and HP Blades and HP iSCSI SAN
by Colin Coe 26 Jun '16

26 Jun '16

Hi all We run four RHEV datacenters, two PROD, one DEV and one TEST/Training. They are all working OK but I'd like a definitive answer on how I should be configuring the networking side as I'm pretty sure we're getting sub-optimal networking performance. All datacenters are housed in HP C7000 Blade enclosures. The PROD datacenters use HP 4730 iSCSI SAN clusters, each datacenter has a cluster of two 4730s. These are configured RAID5 internally with NRAID1. The DEV and TEST datacenters are using P4500 iSCSI SANs and each datacenter has a cluster of three P4500s configured with RAID10 internally and NRAID5. The HP C7000 each have two Flex10/10D interconnect modules configured in a redundant ring so that we can upgrade the interconnects without dropping network connectivity to the infrastructure. We use fat RHEL-H 7.2 hypervisors (HP BL460) and these are all configured with six network interfaces: - eno1 and eno2 are bond0 which is the rhevm interface - eno3 and eno4 are bond1 and all the VM VLANs are trunked over this bond using 802.1q - eno5 and eno6 are bond2 and dedicated to iSCSI traffic Is this the "correct" way to do this? If not, what should I be doing instead? Thanks CC

Should and can I change the hosted_storage entry-point globally to i.e. "microcloud21.rxmgmt.databay.de" or wouldn't it be better globally that VDSM uses "-t glusterfs" to try to mount the gluster-Volume regardless which DNS Name for the gluster-service is used ?

Setup new enviroment
by Andy Michielsen 25 Jun '16

25 Jun '16

Hello all, I was just wondering what your opinions would be in setting up a new oVirt enviroment. I have 4 old servers, 3 with 64 Gigs of ram and 2 tera's of disk space an one with 32 Gigs of ram and 1,2 Gb. Each has 2 hexcore cpu's. Each server has at least 2 nic's. I would like to use each server in a seperate cluster with there own local storage as this would all only be used as a test enviroment but still would like to manage them from one interface. Deploy new vm's from templates etc. Can I still use the all in one installation for engine and node ? Or can I install the engine on a seperate host, physical or virtual. What would be a good way to use the network ? Any advice would be greatly appriciated. Thanks in advance.
